April 15 is built for humans. AI agents don't get a 1040 — but the sales tax, capital gains, and 1099-DA obligations they trigger throughout the year still belong to someone.
Most operators have no idea what their agents owe. AgentTax shows you the exposure before the IRS does.
The entire infrastructure of April 15 — annual filing, withholding, W-2s, refunds — assumes a human taxpayer with an employer relationship. AI agents have none of that. And yet they create real obligations every day.
When millions of agent transactions accumulate without anyone filing, the obligations don't disappear — they sit on the operator's balance sheet, invisible until an audit. We call this the phantom tax gap.
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.
Three months of state and federal tax changes — most agent operators missed all of them.
If your AI agents transacted with anyone in the United States this year, these are the seven things you need to know before April 15.
