About
Column Tax is the first IRS-authorized API-first tax filing product, purpose-built for banks, mobile banking apps, brokerages, and fintech platforms that want to offer seamless, embedded tax filing experiences to their end users. Rather than redirecting customers to third-party tax software, Column Tax lets financial companies embed a fully branded, end-to-end tax filing workflow within their own apps or websites. The platform supports every filer type — from W-2 employees to investors and self-employed freelancers — through two core products: DIY Filing (self-guided) and Expert Review (CPA-assisted). Column Tax pre-fills known customer data to dramatically reduce friction, and its platform collects any remaining information needed to complete an accurate return. For financial businesses, Column Tax delivers measurable ROI: 99% of tax refunds are deposited to embedded partners, 10–25% of users switch their direct deposits after filing, and platforms see 20–35% higher customer retention. Integration is fast — their APIs are designed to get partners from zero to accepted returns in one week or less. Column Tax is SOC 2 certified, uses bank-grade encryption, and boasts 99.999%+ historical uptime. It also handles customer support on behalf of its partners, removing operational burden. Trusted by companies like MoneyLion and Varo, Column Tax turns tax filing into a competitive differentiator for modern financial products.
