Spotted a wage base or bracket that does not match this year's IRS or SSA release, or a withholding number that does not match your own math? Start here.

Most of what lands in this inbox is a number gone stale, an IRS or Social Security release we have not caught up to yet, or a calculator total that a reader's own arithmetic disagrees with. Send the calculator name, the gross pay, pay frequency, and filing status you entered, the state rate if you used one, what the tool showed you, and what you worked out by hand instead. That is enough for a same-day recheck against the source table, and if the reader turns out to be right, the fix ships with a dated note on the page rather than a quiet edit.
We cannot review your actual pay stub, W-4, or tax return, or tell you what to put on either. That is a payroll or tax professional's job, not this form's. What we can do is check a calculator's math against the source table it is built on and correct it if it is wrong.
