What is Column Tax?
Column Tax provides embedded tax filing and expert review for financial apps, banks, and fintech platforms. The company supports more than 1 million filed returns and operates as part of Aiwyn.
Column Tax is an embedded tax engine rather than a standalone consumer tax website. A partner places its white-label interface inside an app or website, pre-fills information the partner already holds, collects remaining data, and connects the completed filing back to the partner product. Its APIs and included UI cover the journey from taxpayer intake through federal and state submission, while Column Tax supplies taxpayer support and handles the regulated filing infrastructure.
The product spans do-it-yourself filing, professional Expert Review, bank solutions, and tools for freelancers and small businesses. It supports individual federal and state returns, including small-business income that flows into a 1040, and offers maximum-refund, accuracy, and audit-assistance guarantees. The trade-off is distribution: filing and support are available through participating partner apps, not as a conventional direct-to-consumer product, and public platform pricing is not listed.
Column Tax is aimed at product, partnerships, and tax teams at banks, fintechs, financial institutions, and vertical software companies that want tax filing inside an existing customer experience. Its partner materials emphasize deposits, acquisition, and retention, while Expert Review adds access to tax professionals for more complex returns. Buyers book a demo and receive quote-based commercial terms; taxpayer access is generally a partner benefit rather than a separately priced consumer subscription.
