Reporting a data error
This is the most useful thing you can send us. To let us reproduce the problem quickly, please include:
- The state you selected.
- Your filing status and pay frequency.
- The gross income you entered (a round approximation is fine — please do not send us your real salary if you would rather not).
- The figure our calculator produced and the figure you believe is correct.
- If you have one, a link to the official source that supports the correct figure.

What happens after you write
Every message is read by a person, not a queue. We aim to reply within three business days, and corrections usually move faster than that because they affect what everyone else sees.
If you report a figure we agree is wrong, three things happen: we fix the underlying data, we regenerate every page that used it, and we update the last-verified date on those pages so readers can see the correction is fresh. We do not quietly edit numbers and pretend they were always right.
If we disagree with a report, we will tell you why and point at the source we relied on. Sometimes two official publications genuinely conflict, particularly when a state changes its rates mid-year, and in that case we say so on the page rather than pick a side silently.
What we cannot help with
We are not tax advisers and cannot answer questions about your personal tax position. Whether you should claim a particular credit, how to correct a filed return, or what your employer should have withheld all need a qualified professional who can see your full situation. The IRS also runs a free helpline and in-person assistance centers for questions about your own account.
We also cannot process payroll, produce payslips, or act for you with any tax authority. This site is a reference tool and nothing more. If you need a filing done, an enrolled agent or a CPA is the right call.
