Know exactly where you stand with HMRC.
Answer seven quick questions about your sales. Get a personal timeline of every rule that applies to you — Self Assessment, platform reporting, Making Tax Digital and VAT — with the dates that matter.
Making Tax Digital counts your sales, not your profit.
£35,000 of sales on £5,000 of profit still puts a sole trader into Making Tax Digital from 6 April 2027. Low-margin sellers are often in sooner than they think.
Six rules, one timeline
The check tells you which of these apply to you, which are coming, and which you can ignore.
Trading allowance
Whether your sales are small enough that you don't need to tell HMRC at all.
Self Assessment
Whether you need to register and file, and your next return and payment dates.
Platform reporting
Which marketplaces send your sales figures to HMRC, and what that does and doesn't mean.
Making Tax Digital
Your start date, when to sign up, and your first quarterly update deadline.
VAT registration
How close your last 12 months are to the threshold. For exact dates, run the VAT check.
Selling to the EU
A flag if EU orders bring extra rules, with the official guidance to read next.
How it works
Answer seven questions
How you trade, what you sold, where you sell. Rough figures are fine.
