About USTaxTools

USTaxTools provides free, accurate tax calculators designed for US taxpayers. Whether you're estimating your federal income tax, planning for capital gains, or evaluating retirement contributions, our tools give you fast, reliable results without the hassle.

All calculators support the 2024 and 2025 tax years and all five filing statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Surviving Spouse.

No signup required. No personal data stored. Every calculation runs entirely in your browser — nothing is sent to a server.

How pages are maintained

We review calculator assumptions and supporting copy against official IRS, SSA, and state tax agency materials. When thresholds or rules change, we update the underlying calculation logic and revise the page copy that depends on those values.

For a fuller description of our workflow, see the Editorial Policy.
