Your AI Agents Will File Zero Returns This Tax Day

AI agents have no taxpayer identification number, no filing requirement, and no annual return. The operator who deployed them is the taxpayer — and most operators have never reconciled what their agents bought.

When an agent purchases compute, data, or API access across state lines, sales tax applies. The agent doesn't know it. The operator usually doesn't know it. Nobody files. Nobody pays. Until an audit.

Agents trading crypto or digital assets at micropayment scale create thousands of taxable lots a year. FIFO/LIFO matching across millions of trades is not something a spreadsheet handles.

The IRS Form 1099-DA reporting requirement for digital asset brokers takes effect for the 2025 tax year. Agents that route trades through a broker now generate reporting obligations.

// List this year's recorded transactions into one state
const res = await fetch(
  "https://agenttax.io/api/v1/transactions?state=TX&since=2026-01-01&limit=1000",
  { headers: { "X-API-Key": "atx_live_..." } }
);

// Returns the matching rows (newest first, up to limit) and a
// summary of sales tax collected and use tax owed across them.
// Run it once per state to build a per-state picture.
