Reporting a wrong figure
We maintain 51 jurisdictions for tax year 2026 by hand. Five lines make a report we can reproduce and fix the same day:
- 1The URL from your address bar — it encodes your inputs.
- 2Salary, filing status, state, and any city or deductions.
- 3The line that is wrong and the figure we showed.
- 4What it should be, and how you got there.
- 5Your source, if you have one — a state schedule or IRS publication.
When a correction lands we change the engine, re-run the verification suite and update the reviewed date on that state's page, so you can see it took.
What we cannot do
We are glad to explain how a calculation works. We cannot give you tax advice — nobody here can see your W-4, benefits elections or residency history, and those are what decide a real tax position. For anything consequential, speak to a CPA or enrolled agent.
We also do not model non-wage income. The methodology lists every simplification we make, and the terms and conditions set out the limits properly.
