Frequently asked questions
- Which tax year is this for?
- Currently uses tax year 2025 federal brackets (IRS Rev. Proc. 2024-40) and 2025 state rates. Filed in early 2026.
- What is included in the calculation?
- Federal income tax (after standard deduction), state income tax, Social Security (6.2% up to $176,100), Medicare (1.45%), and Additional Medicare (0.9% above $200k single / $250k joint).
- Is my data saved anywhere?
- No. Everything runs in your browser. No server-side storage, no logs, no tracking of your income data.
- Does it handle itemized deductions or credits?
- No — this is a straightforward standard-deduction estimator. For itemized deductions, dependents credits, retirement contributions, or tax credits, use IRS Form 1040 or a licensed tax professional.
- Why does my paycheck look different?
- Employer withholding uses IRS tables plus your W-4 allowances, which can differ from annual liability. This tool estimates annual tax owed, not per-paycheck withholding.
- Are these numbers official?
- No. Estimates only. Bracket data follows publicly published IRS and state sources but may be rounded or updated. Always verify with the IRS and your state department of revenue before filing.
