When we find a mistake in a calculator or a guide, or when a tax rule changes, we fix it and record it here with the date, what was wrong, and what changed. This page exists so that you do not have to take our word that the numbers are right. You can see how often we are wrong and how quickly we fix it.
Found something that looks off? Please tell us on the Contact page and include the inputs you used. How we calculate and test is described on the Methodology page.
Change log
| Date | Where | What changed |
|---|---|---|
| Nov 7, 2026 | Paycheck calculator | New. A "Tax year" menu (2026 and 2027). The 2027 federal brackets, standard deductions and Social Security wage base ($192,300) are included from the IRS announcement of November 5, 2026 and the SSA announcement of October 14, 2026. The 401(k) limit and state tables for 2027 are not published yet, so the 2026 values are used and labelled as carried forward. The calculator switches to the new year by itself on January 1. |
| Nov 7, 2026 | Site | New. The Tax Rules and Release Calendar page, and the site name is now Paycheck Lab everywhere. |
| Nov 7, 2026 | Credit card payoff calculator | Correction. When the monthly payment was only slightly above the interest charged, the calculator stopped at 50 years and showed the payoff as "never". The limit is now 100 years, so these slow payoffs show a real payoff date and total interest. A payment at or below the monthly interest still shows that the balance will not be paid off. |
| Nov 7, 2026 | Paycheck calculator | Correction. Wyoming was missing from the state list. All 50 states and the District of Columbia are now included. Wyoming has no state tax on wages. |
| Nov 7, 2026 | All calculators | New. Share link, print, remembered inputs, and a "pin this result to compare" feature were added. |
| Nov 7, 2026 | Site | New. Search and topic filters for the guides, and the Methodology and Corrections pages. |
Our correction policy
- If a number is wrong, we fix the calculator first and then publish the entry here.
- We do not quietly change results. Anything that could change an answer you have already seen is listed above.
- Annual tax-year updates (brackets, deductions, wage bases, contribution limits) are listed here when they go live.
