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.
We publish corrections with the date they were made, and we update the "last verified" stamp on the affected page. See our corrections policy.
