REPORTS TO SHAREOWNERS. ------------------------------------------------------------------------------- PIONEER ----------- TAX ADVANTAGED BALANCED TRUST Semiannual Report 5/31/07 [LOGO] PIONEER Investments Table of Contents ------------------------------------------------------------------------------- Letter to Shareowners 2 Portfolio Summary 4 Prices and Distributions 5 Performance Update 6 Portfolio Management Discussion 7 Schedule of Investments 12 Financial Statements 27 Notes to Financial Statements 32 Trustees, Officers and Service Providers 43 President's Dear Shareowner, -------------------------------------------------------------------------------- Staying diversified and keeping your portfolio invested in the markets are two general investment principles that have served investors well over time. Those were particularly useful guides during the past year, as U.S. and global stock and bond markets grew strongly during the period. In the 12 months ending May 31, 2007, global stock markets were supported by relatively low short-term interest rates and generally strong economies. The U.S. stock market, as measured by the Standard & Poor's 500 Stock Index, gained approximately 23% over the 12-month period. International developed and emerging markets equities performed even better, with MSCI's indexes of those regions rising approximately 27% and 39%, respectively. The general U.S. bond market, as measured by the Lehman Brothers Aggregate Bond Index, returned roughly 7%. The high yield market, as measured by the Merrill Lynch High Yield Bond Master II Index, returned approximately 13% during the same period. While still strong, the rate of U.S. economic growth has slowed over the past year. That was due in large part to a slowdown in new home construction and in part to the lagging effects of rising energy and commodity prices as well as rising short-term interest rates. But slowing economic activity is also due in part to the natural maturation of the cyclical expansion as U.S. factories approach full utilization and the labor markets approach full employment. We have enjoyed a cyclical recovery with strong economic growth, and while U.S. economic growth has slowed, we believe that continuing growth at a slower rate appears to be more likely than a recession. The Federal Reserve Board has indicated a reduced likelihood of future rate hikes, but continues to highlight its commitment to keeping inflationary pressures contained. This is in keeping with "best practices" among the world's central banks: low and stable inflation is believed to be the best backdrop for stable economic growth and low average unemployment. In Europe, healthy labor markets are supporting growing consumption and solid GDP growth, helped by productivity gains and a positive operating environment for European companies that are finding strong export markets for their goods and services around the globe. European inflationary pressures appear to be largely under control, with 2 Letter the European Central bank remaining strongly vigilant. Japanese economic growth continues to make progress, and the country has become a more attractive market as deflationary problems recede. Economic growth in emerging market countries remains faster than in the developed world as they continue to "catch up." Leading the way is China, which continues its rise as a world economic power. Looking forward, we believe that the overall climate for investors generally will continue to be positive, although valuations are less attractive than they were a year ago and a correction after a period of strong performance is possible. Sudden swings in the markets are always to be expected. Just as staying diversified and invested are important investment principles, it is also important to pay attention to asset allocation. As always, we encourage shareholders to work closely with their financial advisor to find the mix of stocks, bonds and money market assets that is aligned to their particular risk tolerance and investment objective.

Current performance may be lower or higher than the performance data quoted. Performance data shown represents past performance. Past performance is no guarantee of future results. Investment return and market price will fluctuate, and your shares may trade below net asset value ("NAV"), due to such factors as interest rate changes, and the perceived credit quality of borrowers. Total investment return does not reflect broker sales charges or commissions. All performance is for common shares of the Trust. Closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and once issued, shares of closed-end funds are sold in the open market through a stock exchange and frequently trade at prices lower than their NAV. NAV is total assets less total liabilities, which includes preferred shares, divided by the number of common shares outstanding. When NAV is lower than market price, dividends are assumed to be reinvested at the greater of NAV or 95% of the market price. When NAV is higher, dividends are assumed to be reinvested at prices obtained under the Trust's dividend reinvestment plan. The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Trust distributions or the redemption of Trust shares. Index comparisons begin January 31, 2004. The Lehman Brothers Municipal Bond Index is a broad measure of the municipal bond market. The Standard & Poor's 500 Stock Index (the S&P 500) is a commonly used measure of the broad U.S. stock market. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Trust returns, do not reflect any fees, expenses or charges. You cannot invest directly in an Index. 6 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 5/31/07 ------------------------------------------------------------------------------- During the six months ended May 31, 2007, shareowners in Pioneer Tax Advantaged Balanced Trust benefited from the performance of two high-quality asset classes - municipal bonds and dividend-paying stocks. Over the period, the Trust's well-diversified portfolio provided a dividend yield that was greater than those of the S&P 500 Index and the Dow Jones Industrial Average. In most instances, the dividends received from the bonds in the portfolio are exempt from federal taxes; and the dividends derived from the portfolio's equities are likely to qualify for the more favorable federal income tax rate of 15%. In the following interview, David Eurkus, who is responsible for the Trust's fixed-income portion, and Walter Hunnewell, Jr., who is responsible for the Trust's equity portion, discuss the Trust's investment strategy and outlook. Q: How did the Trust perform during the period? A: For the six months ended May 31, 2007, Pioneer Tax Advantaged Balanced Trust returned 4.71% at net asset value and 11.63% at market price. As of May 31, 2007, the Trust was selling at a discount of market price to net asset value of 7.70%, compared with a discount of 16.20% on May 31, 2006. For the same period, the Lehman Brothers Municipal Bond Index returned 0.30%, and the S&P 500 Index returned 10.29%. Unlike open-end funds, a closed-end fund's share price goes up and down based on supply and demand, independent of a fund's net asset value, or NAV, per share. It isn't unusual to find closed-end funds trading at a discount. At the end of the period, closed-end funds on average were trading at a discount to their actual net asset value.

The performance data quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, and shares, when redeemed, may be worth more or less than their original cost. Information regarding the Trust's principal investment risks is contained in the Trust's prospectus. Please refer to those documents when considering the Trust's risks. 7 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 5/31/07 (continued) ------------------------------------------------------------------------------- There can be no assurance as to the portion of the Trust's dividends that will be tax-exempt or tax-qualified. A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any are subject to a capital gains tax. When interest rates rise, the prices of fixed-income securities in the Trust will generally fall. Conversely, when interest rates fall the prices of fixed-income securities in the Trust will generally rise. By concentrating in municipal securities, the portfolio is more susceptible to adverse economic, political or regulatory developments than is a portfolio that invests more broadly. Investments in the Trust are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. The Trust may invest in derivative securities, which may include futures and options. These types of instruments can increase price fluctuation. The Trust may use leverage through the issuance of preferred shares with an aggregate liquidation preference of up to 331/3% of the Trust's total assets after such issuance. Leverage creates significant risks, including the risk that the Trust's income or capital appreciation will not be sufficient to cover the cost of leverage, which may adversely affect the return for the holders of common shares. Q: What strategies did you use in managing the Trust? A: We continued to focus on providing income with about a 55%/45% mix of municipal bonds and dividend-paying equity securities. In the fixed-income portion of the Trust, we maintained our emphasis on sectors that are vital components of the U.S. economy. The biggest positions were in health care, education and various other revenue bonds on which the payment of interest and principal depends on revenues generated from the particular asset that the bond was issued to finance. About 23% of the municipal bonds in the portfolio were insured, which means that the interest and principal of these AAA-rated securities are guaranteed by private insurance companies. About 11.5% of the Trust's fixed-income assets were invested in below investment-grade bonds, which outperformed other types of fixed-income assets. On May 31, 2007, the Trust had 121 fixed-income issues in 36 states, territories and the 8 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- District of Columbia. The average credit quality of the fixed-income holdings was A-, compared with A six months ago. In the equity portion of the Trust, we inevitably gravitate to sectors that tend to pay the biggest dividends. When selecting individual securities, we focus on well-established corporations that offer attractive current dividend yields and the best potential for future dividend growth and price appreciation. In addition to owning common equities, we balance our dividend income mandate by owning higher-yielding preferred stocks. This resulted in an approximately equal split between common and preferred stocks. Because of the favorable interest-rate environment, several of our preferred stocks were called; and we invested the proceeds from the called securities in select common and preferred equities with the potential for high current dividend yields and improving creditworthiness. During the reporting period, we made adjustments to the Fund's portfolio. Among equities, we eliminated our position in Ameren, a large regulated electricity and natural gas utility, on concerns about adverse regulatory developments in its important Chicago market. After a strong run-up, we trimmed our overweight in AT&T and used the proceeds to add to Verizon, which we believe may now be in a better position for longer-term earnings growth. We sold ServiceMaster, a provider of cleaning, lawn and pest control services to commercial and consumer customers, when it became the target of a leveraged takeover bid. We took gains in smokeless tobacco manufacturer UST when it reached our target price, and we purchased Altria Group, before it spun off its Kraft Foods subsidiary. We added to Washington Mutual, a position that we had trimmed on price strength last year but now view as attractively priced given the market's strong adverse reaction to sub-prime mortgage woes. On May 31, 2007, 27% of the Trust was leveraged, which means that we borrowed funds at lower rates and invested those funds in high-yielding securities. Our leveraging strategy has aided return for several years. Over the first half of the fiscal year, short-term rates showed little volatility; however, a rise in short-term rates in the future would add to the Trust's borrowing costs, and the ability to sustain present dividend levels could be affected. Should short-term rates decline, the cost of borrowing would go down, providing the Trust with a modest amount of additional income. 9 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- PORTFOLIO MANAGEMENT DISCUSSION 5/31/07 (continued) ------------------------------------------------------------------------------- Q: What contributed to performance? A: Being fully invested and maintaining a longer duration than our fixed-income benchmark, the Lehman Brothers Municipal Bond Index, contributed to both the Trust's tax-free income and principal appreciation. (Duration measures a bond's price sensitivity to interest-rate movements.) In addition, demand for municipal securities was robust, boosting the value of the portfolio's securities. Our holdings in below investment-grade bonds also aided return. Stock investments in the telecommunications, consumer staples and health care sectors were the largest contributors to total return. In telecommunications, AT&T and Verizon were standout performers, returning 24% and 27%, respectively, during the reporting period as the market cheered industry consolidation and the potential for growth from telecommunications and residential video products. Other companies with notable performance included Carolina Group (+26%), the tobacco tracking stock of Lowes, Bristol-Myers Squibb (+25%) and Merck & Co. (+20%). Q: What detracted from performance? A: Among our municipal bond investments, there were no notable detractors from performance; however, the higher quality bonds in the portfolio underperformed the lower quality securities, which accounted for only about 10% of the Trust's assets. Adverse stock selection in the marginally weighted energy sector was negative for return. For example, Duke Energy's natural gas spin-off, Spectra Energy, declined almost 7.0% during the reporting period. Other holdings that were disappointing included: Kimball International, a manufacturer of office and health care furniture; TrustCo Bank, which was adversely affected by the flat yield-curve environment; and our SLM preferred holding, which was volatile in the wake of its announced leveraged acquisition. 10 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- Q: What is your outlook? A: We believe the trend of the economy may be stronger than previously thought; and while the Federal Reserve has kept interest rates at 5.25%, the central bank continues to express concerns about the potential for accelerating inflation. Over the last few weeks, we have seen intermediate and long-term market interest rates rise. If this trend continues, there would be more opportunity to increase the portfolio's yield. As always, we will continue to seek relatively high levels of current income from fixed-income and dividend-producing preferred and common stocks, while maintaining our strong emphasis on quality.

Organization and Significant Accounting Policies Pioneer Tax Advantaged Balanced Trust (the "Trust") was organized as a Delaware statutory trust on October 16, 2003. Prior to commencing operations on January 30, 2004, the Trust had no operations other than matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended. The Trust's investment objective is to provide a high level of total after-tax return, including attractive tax-advantaged income. The Trust may invest in municipal securities with a broad range of maturities and credit ratings, including both investment grade and below investment grade municipal securities. By concentrating in municipal securities, the portfolio is more susceptible to adverse economic, political or regulatory developments than is a portfolio that invests more broadly. Investments in the Trust are subject to possible loss due to the financial failure of underlying securities and their inability to meet their debt obligations. The Trust may also invest in common stocks and preferred securities that pay tax-qualified dividends. In addition, the Trust may invest in other securities, including debt instruments, real estate investment trusts ("REITS") and equity securities, that generate income taxable at ordinary income rates, rather than long-term capital gain rates. There can be no assurance as to the portion of the Trust's dividends that will be tax-exempt or tax-qualified. A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. When interest rates rise, the prices of fixed-income securities in the Trust will generally fall. Conversely, when interest rates fall the prices of fixed-income securities in the Trust will generally rise. The Trust may invest in derivative securities, which may include futures and options. These types of instruments can increase price fluctuation. Information regarding the Trust's principal risks is contained in the Trust's original offering prospectus, with additional information included in the Trust's shareowner reports. Please refer to those documents when considering the Trust's risks. At times, the Trust's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any 32 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- economic, political, or regulatory developments or other risks affecting those industries and sectors. The Trust's financial statements have been prepared in conformity with U.S. generally accepted accounting principles that require the management of the Trust to, among other things, make estimates and assumptions that affect the reported amounts of assets and liabilities, and the reported amounts of income, expenses and gains and losses on investments during the reporting period. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Trust in preparation of its financial statements, which are consistent with those policies generally accepted in the investment company industry: A. Security Valuation Security transactions are recorded as of trade date. Debt securities are valued at prices supplied by independent pricing services, which consider such factors as Treasury spreads, yields, maturities and ratings. Valuations may be supplemented by dealers and other sources, as required. Equity securities are valued at the last sale price on the principal exchange where they are traded. The values of interest rate swaps are determined by obtaining dealer quotations. Securities for which market quotations are not readily available are valued at their fair values as determined by, or under the direction of, the Board of Trustees. The Trust may also use the fair value of a security, including a non U.S. security, when the closing market price on the principal exchange where the security is traded no longer accurately reflects the value of the security as of the close of the exchange. As of May 31, 2007, there were no securities fair valued. Temporary cash investments are valued at net asset value. Dividend income is recorded on the ex-dividend date, except that certain dividends from foreign securities where the ex-dividend date may have passed are recorded as soon as the Trust becomes aware of the ex-dividend data in the exercise of reasonable diligence. Discount and premium on debt securities are accreted or amortized, respectively, daily, on an effective yield to maturity basis and are included in interest income. Interest income, including 33 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/07 (unaudited) (continued) ------------------------------------------------------------------------------- income on interest bearing cash accounts, is recorded on an accrual basis. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes. B. Federal Income Taxes It is the Trust's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable income and net realized capital gains, if any, to its shareowners. Therefore, no federal income tax provision is required. The amounts and characterizations of distributions to shareowners for financial reporting purposes are determined in accordance with federal income tax rules. Therefore, the source of the Trust's distributions may be shown in the accompanying financial statements as either from or in excess of net investment income or net realized gain on investment transactions, or from paid-in capital, depending on the type of book/tax differences that may exist. The tax character of current year distributions paid to common and preferred shareowners will be determined at the end of the current fiscal year. Distributions during the year ended November 30, 2006 were as follows: ------------------------------------------------------------------------------- 2006 ------------------------------------------------------------------------------- Distributions paid from: Tax-Exempt income $13,521,779 Ordinary income 13,026,310 Long-term capital gain 2,887,176 ----------- $29,435,265 =========== ------------------------------------------------------------------------------- 34 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- The following shows the components of distributable earnings on a federal income tax basis at November 30, 2006. ------------------------------------------------------------------------------- 2006 ------------------------------------------------------------------------------- Undistributed tax-exempt income $ 590,795 Undistributed ordinary income 555,079 Undistributed long-term gain 446,744 Dividends payable (93,771) Unrealized appreciation 54,432,253 ----------- Total $55,931,100 =========== ------------------------------------------------------------------------------- The difference between book basis and tax basis unrealized appreciation is primarily attributable to the difference between book and tax amortization methods for premiums and discounts on fixed income securities, the accounting treatment for swap agreements and the deferral of Post-October losses for tax purposes. C. Automatic Dividend Reinvestment Plan All common shareowners automatically participate in the Automatic Dividend Reinvestment Plan (the "Plan"), under which participants receive all dividends and capital gain distributions (collectively, "dividends") in full and fractional common shares of the Trust in lieu of cash. Shareowners may elect not to participate in the Plan. Shareowners not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notifying American Stock Transfer & Trust Company, the agent for shareowners in administering the Plan (the "Plan Agent"), in writing prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution. Whenever the Trust declares a dividend on common shares payable in cash, participants in the Plan will receive the equivalent in common shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized common shares from the Trust or (ii) by purchase of outstanding common shares on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend, the net asset value per common share is equal to or less than the market price per share plus estimated brokerage 35 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/07 (unaudited) (continued) ------------------------------------------------------------------------------- trading fees ("market premium"), the Plan Agent will invest the dividend amount in newly issued common shares. The number of newly issued common shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per common share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per common share is greater than the market value ("market discount"), the Plan Agent will invest the dividend amount in common shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued common shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent's open-market purchases. Participating in the Plan does not relieve shareowners from any federal, state or local taxes which may be due on dividends paid in any taxable year. Shareowners holding Plan shares in a brokerage account may not be able to transfer the shares to another broker and continue to participate in the Plan. 2. Management Agreement Pioneer Investment Management, Inc. ("PIM"), a wholly owned indirect subsidiary of Unicredito Italiano S.p.A. ("Unicredito Italiano") manages the Trust's portfolio. Management fees payable under the Trust's Advisory Agreement with PIM are calculated daily at the annual rate of 0.60% of the Trust's average daily managed assets. "Managed assets" is the average daily value of the Trust's total assets minus the sum of the Trust's liabilities, which liabilities exclude debt related to leverage, short-term debt and the aggregate liquidation preference of any outstanding preferred shares. Also, PIM has agreed for the first three years of the Trust's investment operations to limit the Trust's total annual expenses excluding offering costs for common and preferred shares, interest expense, the cost of defending or prosecuting any claim or litigation to which the Trust is a party (together with any amount in judgment or settlement), indemnification expenses or taxes incurred due to the failure of the Trust to qualify as a regulated investment company under the Code or any other non-recurring or non-operating expenses to 0.80% of the Trust's average daily managed assets. The dividend on any preferred shares is not an expense for this purpose. As of February 2, 2007, the expense limitation was no longer in effect. For the six months ended May 31, 2007, the 36 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- Trust's expenses were not reduced under such arrangements. For the six months ended, May 31, 2007, the net management fee was equivalent to 0.60% of the Trust's average daily managed assets, which was equivalent to 0.83% of the Trust's average daily net assets attributable to common shareowners. In addition, under PIM's management and administration agreements, certain other services and costs are paid by PIM and reimbursed by the Trust. For the six months ended May 31, 2007, $341,557 was payable to PIM related to management costs, administrative costs and certain other services and is included in due to affiliates. The Trust has retained Princeton Administrators, LLC, ("Princeton") to provide certain administrative services to the Trust on its behalf. The Trust pays Princeton a monthly fee at an annual rate of 0.07% of the average daily value of the Trust's managed assets up to $500 million and 0.03% for average daily managed assets in excess of $500 million, subject to a minimum monthly fee of $10,000. 3. Transfer Agents Pioneer Investment Management Shareholder Services, Inc. ("PIMSS"), a wholly owned indirect subsidiary of UniCredito Italiano, through a sub-transfer agency agreement with American Stock Transfer & Trust Company, provides substantially all transfer agent and shareowner services related to the Trust's common shares at negotiated rates. Deutsche Bank Trust Company Americas ("Deutsche Bank") is the transfer agent, registrar, dividend paying agent and redemption agent with respect to the Trust's Auction Market Preferred Shares ("AMPS"). The Trust pays Deutsche Bank an annual fee, as is agreed to from time to time by the Trust and Deutsche Bank, for providing such services. 4. Interest Rate Swaps The Trust may enter into interest rate swap transactions to attempt to protect itself from increasing dividend or interest expense on its leverage resulting from increasing short-term interest rates. The cost of leverage may rise with an increase in interest rates, generally having the effect of lower yields and potentially lower dividends to common shareowners. Interest rate swaps can be used to "lock in" the cost of leverage and reduce the negative impact that rising short-term interest rates would have on the Trust's leveraging costs. 37 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/07 (unaudited) (continued) ------------------------------------------------------------------------------- An interest rate swap is an agreement between two parties, which involves exchanging a floating rate and fixed rate interest payments for a specified period of time. Interest rate swaps involve the accrual of the net interest payments between the parties on a daily basis, with the net amount recorded within the unrealized appreciation/ depreciation of interest rate swaps on the Statement of Assets and Liabilities. Once the interim payments are settled in cash, at the pre-determined dates specified in the agreement, the net amount is recorded as realized gain or loss from interest rate swaps on the Statement of Operations. During the term of the swap, changes in the value of the swap are recognized as unrealized gains and losses by "marking-to market" the market value of the swap based on values obtained from dealer quotations. When the swap is terminated, the Trust will record a realized gain or loss equal to the difference, if any, between the proceeds from (or cost of) closing the contract and the cost basis of the contract. The Trust is exposed to credit risk in the event of non-performance by the other party to the interest rate swap. However, at May 31, 2007 the Trust does not anticipate non-performance by any counterparty. Risk may also arise with regard to market movements in the value of the swap arrangement that do not exactly offset the changes in the related dividend requirement or interest expense on the Trust's leverage. Under the terms of the agreement entered into by the Trust, the Trust receives a floating rate of interest and pays a fixed rate of interest for the term. Details of the swap agreement outstanding as of May 31, 2007 were as follows: ------------------------------------------------------------------------------- Termination Notional Unrealized Counterparty Date Amount (000) Fixed Rate Floating Rate Appreciation ------------- ---- ------------ ---------- ------------- ------------- UBS AG Sept. 1, 2009 $106,000 2.855% 1 month BMA $1,734,541 5. Trust Shares There are an unlimited number of common shares of beneficial interest authorized. Of the 28,706,981 common shares of beneficial interest outstanding at May 31, 2007, PIM owned 6,981 shares. During the six months ended May 31, 2007 and year ended November 30, 2006, there were no share transactions by the Trust. All reinvested distributions were satisfied with previously issued shares 38 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- purchased in the open market and by the Plan Agent and credited to shareowner accounts. The Trust may classify and reclassify any unissued common shares of beneficial interest into one or more series of preferred shares of beneficial interest. As of May 31, 2007, there were 7,050 AMPS as follows: Series T7-2,350, Series F7-2,350 and Series TH28-2,350. Dividends on Series T7 and Series F7 are cumulative at a rate which is reset every seven days based on the results of an auction. Dividends on Series TH28 are also cumulative at a rate reset every 28 days based on the results of an auction. Dividend rates ranged from 4.00% to 5.30% during the six months ended May 31, 2007. The Trust may not declare dividends or make other distributions on its common shares or purchase any such shares if, at the time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred shares would be less than 200%. The AMPS are redeemable at the option of the Trust, in whole or in part, on any dividend payment date at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared. The AMPS are also subject to mandatory redemption at $25,000 per share plus any accumulated or unpaid dividends, whether or not declared, if certain requirements relating to the composition of the assets and liabilities of the Trust as set forth in the Agreement and Declaration of Trust are not satisfied. The holders of AMPS have voting rights equal to the holders of the Trust's common shares (one vote per share) and will vote together with holders of the common shares as a single class. However, holders of AMPS are also entitled to elect two of the Trust's Trustees. In addition, the Investment Company Act of 1940, as amended, requires that along with approval by shareowners that might otherwise be required, the approval of the holders of a majority of any outstanding preferred shares, voting separately as a class, would be required to (a) adopt any plan of reorganization that would adversely affect the preferred shares and (b) take any action requiring a vote of security holders, including, among other things, changes in the Trust's subclassification as a closed-end investment company or changes in its fundamental investment restrictions. 39 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/07 (continued) ------------------------------------------------------------------------------- 6. New Pronouncements On July 13, 2006, the Financial Accounting Standards Board ("FASB") released FASB Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" ("FIN 48"). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Trust's tax returns to determine whether the tax positions have a "more-likely-than-not" probability of being sustained by the applicable tax authority. Tax positions deemed to not meet the more-likely-than-not threshold would be recorded as a tax benefit or expense in the reporting period in which they are realized. Adoption of FIN 48 is required for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years no later than November 30, 2007. At this time, management is evaluating the implications of FIN 48 and any impact in the financial statements has not been determined. In addition, in September 2006, Statement of Financial Accounting Standards No. 157 Fair Value Measurements ("SFAS 157") was issued and is effective for fiscal years beginning after November 15, 2007. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. At this time, management is currently evaluating the implications of SFAS 157 and its impact on the Trust's financial statement disclosures, if any, has not yet been determined. 7. Subsequent Events Subsequent to May 31, 2007, the Board of Trustees of the Trust declared a dividend from undistributed net investment income of $0.061 per common share payable June 29, 2007 to common shareowners of record on June 15, 2007. Subsequent to May 31, 2007, dividends declared and paid on preferred shares totaled $700,371 in aggregate for the three outstanding preferred share series through July 9, 2007. On June 19, 2007, the Trustees of the Trust voted to adopt a new level distribution policy. The Trust's new level distribution policy is meant to provide investors with a relatively stable monthly distribution out of a combination of current net investment income and paid-in capital beginning with the July 2007 payment. The Trust expects to distribute its long term capital gains in November 2007. The Trust is 40 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- ------------------------------------------------------------------------------- applying to the Securities and Exchange Commission for exemptive relief to allow the Trust to include long-term capital gains in its monthly distributions. The exact amount of the level monthly distributions may be adjusted from time to time by the Trustees to reflect current conditions. However, under the Investment Company Act of 1940, the Trust is required to estimate and indicate the source of each monthly distribution to its shareowners. This estimated source may vary from month to month because it may be materially affected by changes in the cumulative level and composition of the Trust's actual earnings from its investment activities and the level of expenses. Shareowners should understand that distributions from paid-in capital (i.e. return of capital) are not from earnings of the Trust. Such return of capital components of the Trust's monthly distributions do not necessarily reflect the Trust's investment performance and should not be confused with "yield" or "income" of the Trust. At the Trust's fiscal year end (November 30) the Trust will determine if any portion of the reported distributions from paid-in capital need to be re-characterized for tax purposes as taxable ordinary income and reportable to shareowners and the IRS on Form 1099 DIV. In January 2008, shareowners will receive a Form 1099 DIV, which will show the amount and composition of all 2007 distributions paid to them from the Trust. That form will provide shareowners with information as to the appropriate tax treatment of each component. The annual meeting of shareholders of the Trust was held on Friday, June 8, 2007. Shareholders of the common shares and the preferred shares, voting as a single class, elected Arthur D. Lipson and Robert Ferguson as Trustees. The election of the Trustee designated to be elected by the holders of the Trust's preferred shares was adjourned due to a lack of a quorum. The Trust will disclose detailed voting results in its annual report. 41 Pioneer Tax Advantaged Balanced Trust ------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS 5/31/07 (continued) ------------------------------------------------------------------------------- ADDITIONAL INFORMATION (unaudited) During the period, there were no material changes in the Trust's investment objective or fundamental policies that were not approved by the shareowners.

PIONEER FUNDS APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES PROVIDED BY THE INDEPENDENT AUDITOR SECTION I - POLICY PURPOSE AND APPLICABILITY The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Pioneer Investment Management, Inc ("PIM"), the audit committee and the independent auditors. The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence. Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii). In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived. Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
