Filed is an AI tax platform for accounting firms and tax professionals. It reads source documents (W-2s, 1099s, K-1s, brokerage statements, prior-year returns), compares them line by line against the draft return to catch errors and find optimizations, performs actual data entry into professional tax software (Drake, ProConnect, UltraTax, CCH Axcess, Lacerte, ProSeries), and evaluates 120+ tax strategies to produce client-ready tax plans with citations. Firms keep the tax software they already use; Filed sits inside the existing workflow via three products — Filed Reviewer, Filed Prep, and Filed Tax Planner. Filed exposes a GraphQL API (router.apps.filed.com/graphql), a remote MCP server, and an embeddable binder UI. Backed by Northzone, Day One Ventures, and Neo.
