Tell us what to fix

PayReckon is only as good as its figures. If something looks wrong, is broken, or is missing, this is the place to say so.

What is this about?

Your message

If a figure looks wrong, the inputs you used and the number you expected help most.

No contact details are collected, so we cannot reply directly.

Corrections come first

If a number looks wrong, that is the most useful thing you can send. Include the inputs you used and the figure you expected, and it can be checked against the published HMRC rates directly.

Every rate is cited

Before reporting a rate as incorrect, it may be worth checking the guides — each tax year's figures are taken from gov.uk and gov.scot, and the source is cited alongside the calculation.

Not a substitute for advice

PayReckon cannot answer questions about your own tax position or contract. For that, speak to a qualified accountant who can see the full picture.
