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.
