K1x, the fintech company behind the industry-leading 990 Tracker ®, today announced a strategic partnership with Labyrinth Inc., the nation’s leader in nonprofit compliance services with more than 35 years of experience supporting mission-driven organizations.

The partnership expands the capabilities of K1x’s 990 Tracker®, the industry-standard platform for IRS-certified Form 990 e-filings. Through this collaboration, nonprofits can now fundraise confidently knowing they are in compliance with charitable registration, annual report, fundraising disclosure, and registered agent requirements directly within 990 Tracker®. By uniting federal and state compliance in one seamless workflow, the integration eliminates redundant manual processes and reduces the need for multiple vendors.

“For years, our 990 Tracker® clients have asked for support with state filings, including charitable registrations and renewals,” said John LaMancuso, CEO of K1x Inc. “By partnering with Labyrinth, we’re able to deliver exactly what they’ve been asking for: a seamless, efficient way to manage both federal and state compliance in one place. This collaboration helps nonprofit leaders and their advisors to save time, reduce risk, and focus their energy where it matters most: advancing their mission.”

“Partnering with K1x brings the power of Labyrinth’s state compliance services directly into 990 Tracker®, combining federal and state filing workflows. For enterprise nonprofits, this means they can automate regulatory tasks to maintain focus on their most pressing causes. Leading accounting firms will now have a simple, scalable way to support clients’ nationwide charitable registration needs—expanding the value they already deliver in tax and attest services,” said Mike Montali, CEO of Harbor Compliance.

Together, K1x and Labyrinth bring unmatched expertise and scale to the nonprofit sector. Labyrinth has guided thousands of organizations through regulatory requirements for decades, serving more than 60% of nonprofits registered to raise funds nationwide. K1x, with its 990 Tracker ® software, streamlines workflows including data collection, analysis, reporting, integration, and IRS-approved e-filing for tax-exempt organizations, including universities, endowments, health systems, and the accounting firms that serve them. By combining forces, the two organizations are delivering a comprehensive solution designed to achieve compliance and help nonprofits operate more efficiently.

The partnership is effective immediately, and current 990 Tracker® customers can now access these expanded services as part of their existing platform.
