Corrections
If a figure on this site is wrong, we want to know. We read every report and fix confirmed errors as a priority.
How to report an error
Use the form below. The most useful reports say which page you were on, what you entered, what the page showed and what you expected. If you have an official source that shows a different figure, please include the link.
You do not need to send your real salary. Any figure that shows the problem is enough.
Report a mistake
That did not send. Please try again in a moment.
Thank you. We check every report against the official source.
What we do with a report
We check the figure against its official source and against our second, independent calculation. If the page is wrong, we fix it, add a test so the same error cannot come back, and list the fix below with the date. If the page is right but the wording caused confusion, we make it clearer.
For a reply, use the contact form and include an email address.
How we keep figures up to date
Tax rates change each April, and sometimes during the year. When they do, we check each new figure against its official source, update our sources list, rerun all our tests and rebuild every page that uses the figure. Pages show the tax year they apply to.

26 October 2026: teacher pension tiers and tax bands
Some sentences on the England, inner London and outer London teacher pay pages still described pension tiers and tax bands from the 2025 pay scale after the pages moved to the 2026 award on 3 October. For example, the outer London page said U3 was the first classroom point with higher rate tax, when U2 is. The pay tables and calculator figures were correct. Those sentences are now worked out from the same calculation as the tables. The Wales page now uses the Wales 2026-27 pay document published on 22 October.
25 October 2026: NHS Scotland part-time pay
The NHS pay calculator worked out part-time pay in Scotland from a 37.5-hour week. NHS Scotland's standard week has been 36 hours since 1 April 2026. Part-time results for Scotland were too low: for a Band 5 entry-point worker on 30 hours, gross pay showed £27,635.20 a year instead of £28,786.67. The calculator now uses 36 hours for Scotland and 37.5 hours for England and Wales. Full-time results did not change.
16 October 2026: old answers after invalid inputs
On the pro rata calculator and pension tax relief calculator, an old answer could stay visible after an input became invalid. No wrong figure was calculated, but the old answer could look current. The fix was prepared on 15 October and released on 16 October. Invalid inputs now hide all old answers and Calculate focuses the field that needs correction.
10 October 2026: pension contribution and relief labels
The pension tax relief calculator described the contribution percentage as what you pay, although it includes provider relief for relief at source. It now says gross contribution. Salary sacrifice results now name tax and National Insurance savings separately. We also corrected the claim that low earners in net pay schemes get no relief: the estimate excludes a separate annual HMRC payment for eligible members. The calculations did not change.
4 October 2026: employer NI sharing unit
On the salary sacrifice calculator, the employer National Insurance sharing field showed a pound sign although it takes a percentage. We changed the field to show a percent sign. The calculation did not change.
1 October 2026: ADS minimum purchase price
The LBTT calculator previously added the Additional Dwelling Supplement to purchases below £40,000 when the additional dwelling option was selected. This is fixed: the calculator now excludes ADS below that price, in line with Revenue Scotland's ADS guidance.
27 September 2026: Scottish pension relief at source
The take-home pay calculator and pension tax relief calculator did not include extra Scottish relief at source above the basic rate. We corrected the income tax band extension and the resulting relief and take-home estimates. The methodology now describes the Scottish calculation.
26 September 2026: Scottish extra relief display
The pension tax relief calculator could show no extra relief to claim for Scottish taxpayers while that relief was not yet included in the calculation. We hid that claim until the calculation was corrected on 27 September.
23 September 2026: tax-code tax-free pay
The take-home pay calculator used the personal allowance directly instead of the tax-free pay applied through a PAYE tax code. We corrected this, which changed income tax and take-home estimates on pages that use the same calculation. The methodology explains the distinction.
23 September 2026: property tax results did not update
The Stamp Duty, LBTT and LTT pages did not load their calculator scripts. Their starting examples could stay visible when inputs changed. The scripts now load and update the results.
22 September 2026: salary page claims
We corrected wording on the salary after tax pages about student loan thresholds, the Scottish tax crossover and pension relief at source. Some pages placed the start of repayments or a tax boundary at the wrong salary. Others did not say that extra relief at source must be claimed from HMRC. The displayed calculations did not change.
