Before you write
Many answers live in the FAQ on the homepage: which tax year the calculator uses, how pre-2020 and post-2020 W-4s differ, and how precise state estimates are.
If a number looks off against your pay stub, check the three most common causes first: pre-tax deductions (401(k) and insurance premiums), your state's standard deduction, and local county or city taxes, which apply only when you select a locality.
Found a data issue?
Tax schedules change. If you spot a rate that looks wrong for 2026, email us the state (and locality, if relevant), the figure you expected, and a link to the official source — we prioritize verified corrections.
