Especially welcome:

Corrections. Tax figures age and change — if a bracket, threshold, rate or deadline on this site has gone stale or was wrong, tell us, ideally with a link to the IRS source. Keeping the numbers page accurate and honestly dated is the most useful thing this site does.
Calculation bugs. Math that surprised you, a result that disagrees with your tax software, a browser where something misbehaves. Describe the inputs in round numbers — please don’t email your real financial details; a mocked-up example shows the bug just as well.
Missing situations. A kind of income, deduction or filing wrinkle the estimator handles badly or the guides don’t cover? Tell us what you expected to find.

Two things we can’t do: recover your saved numbers (they live in your browser, not with us — we never had them), and give tax advice for your personal situation (we publish general information; a credentialed preparer is the right person for your specifics).
