Your taxes, filed by AI.

Tell your AI agent to file your taxes. It calls our API. Done in 60 seconds.

How it works

Three steps. Zero forms.

📄

Upload your tax docs

Drop your W-2s, 1099s, and other docs into your AI agent — Claude, GPT, or any MCP-compatible assistant.

Agent calls the API

Your agent extracts the data, structures it, and sends it to the filedby.ai API with a single call.

We e-file with the IRS
