Corrections Policy
Last updated: 13 November 2026
We work hard to keep every figure correct, but tax bands change, rates move and mistakes happen. When we get something wrong, we fix it and say so.
How to report an error
Send us the details through our Contact page or by email to contact@sumkittool.com. Please include:
- The address (URL) of the page with the error.
- The figure that looks wrong, and what you think it should be.
- The source for the correct figure, if you have one.
What happens next
We check every report against the official source for that figure — for example, the IRS, GOV.UK or Freddie Mac. If the figure is wrong, we correct the tool. If the error is material, we note the correction on the affected page, with the date it was fixed. If the figure is right, we explain why, and add the explanation to the page when it helps other readers.
What counts as a material error
A wrong tax band, rate, formula or result is material. A typo that does not change any result is fixed without a note.
Where corrections are shown
Significant corrections are noted on the page they affect, with the date of the fix, so readers can see what changed and when. Our Editorial Process explains how we check figures before they are published.
