Early access waitlist · IRS credentialing in progress

Tax filing, as a tool call.

We are building MCP and API infrastructure so software and AI agents can prepare and transmit U.S. federal tax returns to the IRS. The service is not live yet. Join the waitlist and we will email you when access opens.

Get early access

Validate before you file

Planned pre-submission checks against published IRS business rules, so common errors are caught early.

Built for agents and firms

Planned MCP tools and a REST API for AI agents, accounting platforms and payroll systems.

Employment tax first

We plan to start with Forms 940, 941 and 944, then expand. Timelines depend on IRS approvals.

What it could look like

// Illustrative example only. This is not a live service.
const result = await mcp.submit_return({
  form: "941",
  quarter: "2026-Q2",
  ein: "XX-XXXXXXX"
});

Planned interface. Names, parameters and responses will change. Pricing will be announced at launch.

Where we are

Filing returns electronically with the IRS requires authorization and software testing. We are applying for the required IRS e-file credentials and have not yet been approved. Until we are, we cannot file returns for anyone.
