Filed
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.
Filed is listed with 1 API on the APIs.io network. Tagged areas include Company, Tax, Accounting, Artificial Intelligence, and Document Processing.
Filed’s developer surface includes engineering blog, pricing, signup flow, support, authentication, and 18 more developer resources.
Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| RPA and Document AI (RPA marketplaces, intelligent document processing) | undeclared | - | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
