We read every message. Whether you want to request a new calculator, report a bug, or suggest an improvement, we'd love to hear from you.

Who runs PayToolkit and how we handle your message

PayToolkit is a UK tax and money calculator site founded by Rasika Gamage, who builds and maintains the calculators and guides. The logic of the key tax calculators is reviewed by J Perera (CIMA). We are a small team, so every message is read by a person, and we aim to reply within two working days.

If you report a mistake, we check it against the official source, usually GOV.UK or HMRC, and fix it across every page where the same figure appears. Significant corrections are recorded in the log on our editorial policy page. Our sources and the way we calculate Income Tax, National Insurance and council tax are explained on the tax calculation sources page and the accuracy and disclaimer page.

What helps us answer faster

For a calculator problem, tell us which calculator, what you entered and the result you expected, and attach a screenshot if you can. For a request about a rate or threshold, link to the GOV.UK or HMRC page you are relying on. For a new calculator idea, describe the situation you were trying to work out, because that helps us decide what to build.

Before You Contact

Bug reports: Please include the calculator name, the numbers you entered, and what result you expected vs. what you got. Screenshots help.

Tax advice: We cannot provide personalised tax advice via email. Our calculators are educational tools. For complex situations, please consult a qualified accountant.

Data issues: We do not store your calculator inputs. If you refresh the page, your numbers disappear. This is by design for privacy.
