Declared limitations
- The plugin has published figures and a simple estimate; it never fills in or files anything. Expected: Does not call the tool to prepare a return. Explains that it only looks up federal figures and gives estimates, and cannot prepare or file a return.
- State tax is outside the federal tables the plugin holds. Expected: Does not call estimate_federal_tax for a state figure. Says the plugin covers US federal tax only and does not cover state taxes.
- The plugin looks up published rules; it registers no one and holds no reduced rate tables. Expected: Does not register anything. May call tax_duty for the standard rate and registration limit, and says reduced rates are not in the table and to check with an accountant or the tax authority.

Description
From the marketplace listing
Get the US federal tax numbers right, with the IRS document each one comes from. Ask "what are the 2026 tax brackets for a married couple?", "what is the standard deduction for head of household?", "what was the IRS mileage rate on 15 March?", "when is the next estimated tax payment due?" or "roughly how much federal tax on $90,000 of wages and $30,000 of freelance income?". Tax Numbers holds the federal income tax figures for tax years 2025 and 2026: brackets, standard deduction, long-term capital gains thresholds, the Social Security wage base and self-employment tax, 401(k) and IRA limits, the standard mileage rates, and the filing and estimated-payment deadlines. Every figure comes with the Revenue Procedure, notice or IRS page it was read from, and every answer says when the table was last verified. A year is added only after all of its figures have been checked. It can also work out a simple federal estimate: standard deduction only, with self-employment tax, long-term capital gains and the Additional Medicare Tax. Every estimate lists its assumptions and what it leaves out (credits, state tax, alternative minimum tax, itemized deductions and more), and says it is an estimate and not tax advice. It also answers a seller's question about registration: tax_duty takes where you sell from, where your buyers are (an EU country, the United Kingdom or a US state), what you sell and your yearly sales, and says whether you must register, the limit, the standard rate and how often you file. Every answer links the official tax authority page it comes from, shows the day that page was read and ends with a note to check with an accountant. It covers the 27 EU member states with the One Stop Shop limit of 10,000 EUR, the United Kingdom and 14 US states. A place that is not in the table gets an explicit not covered answer with the list of places that are, never a guess. Reduced rates, local taxes, sales to businesses and domestic limits inside an EU country are not included. It does not fill in or file returns, give advice on what to do, or cover US state income tax. Your figures are used for the one calculation and are not stored; the only lasting record is a daily count of calls per tool.
