How this service works
Full 2026 tax estimate in one call: federal income tax + self-employment tax + employee FICA + state income tax, from wages, self-employment income, and other income — with the component breakdown, effective and marginal rates, and after-tax income.
Output
Returns a full 2026 tax estimate with itemized components: federal income tax, self-employment tax, employee FICA, and state income tax amounts; effective and marginal tax rates; and after-tax (net) income — all computed from the provided wages, self-employment income, other income, filing status, state, deduction type, adjustments, and credits.
Example use cases
Example prompt
“Can you estimate my total 2026 tax bill? I'm a single filer in California with $90,000 in wages and $30,000 in self-employment income, taking the standard deduction, with no credits or adjustments — I need the federal, self-employment, FICA, and state income tax broken out with my effective and marginal rates.”

Use this endpoint when you need a single-call comprehensive US tax estimate for 2026 that covers all major tax components — federal income, SE tax, FICA, and state — with breakdown and rate data. Prefer this over generic tax calculators when you need structured JSON output with component-level detail suitable for downstream financial planning, or when you need to handle mixed income types (wages + self-employment + other) in one shot.
