About
An independent site for sole trader figures.
TraderFigures is for people in the UK who work for themselves and want to see the arithmetic before they file. It is not part of HMRC or GOV.UK.
The calculators cover take-home pay, VAT, Making Tax Digital for Income Tax, and payments on account. The guides explain the rules those calculators rely on, in plain English, and link back to the GOV.UK pages.
Rates and thresholds are stored in src/data/tax, one file for each Income Tax year, plus files for VAT and Making Tax Digital because those rules are not set on the 6 April to 5 April cycle in the same way. They were last checked on 15 November 2026. If a figure could not be confirmed, the code comment says UNVERIFIED and the relevant page says so in words.
The site can carry affiliate links to accounting and tax software. Those links live on the software comparison, they are labelled, and they are still placeholders. The calculators do not prefer a product.
TraderFigures does not offer personalised tax advice, complete a return, or act as your agent. If the result would change a decision about what you owe, use the GOV.UK guidance or a qualified adviser, and use the figures here as a way to understand the question.
