How the check works

Updated 30 July 2026. Figures checked against the GOV.UK pages linked below.

The free check gives you two answers: whether a platform would normally have reported your selling to HMRC, and whether tax would normally come into it. This page sets out exactly how those answers are produced, what the check deliberately does not do, and how to tell us if we have something wrong.

What the check applies

Every figure the check uses is a published GOV.UK figure. There are only three moving parts.

Before any of that arithmetic, the check asks what kind of selling this was, because the tax test is intention: buying or making things in order to sell them is trading, and selling your own possessions generally is not, whatever the item count. If you skip those questions, the check assumes trading activity and tells you it made that assumption.

What it does not do

How the answer is produced

The answer is computed, not composed. Three design rules keep it honest.

Not sure where you stand? The free check asks a few questions about your selling and gives you a straight answer: were you reported, would tax normally be due, and what to do next. Every figure links to its GOV.UK source. Nothing is sent to HMRC.

Anonymity and what is stored

The check needs no signup, no email and no name. What we store from an anonymous check is the answers you entered, the verdict, and the rule set version that produced it, kept under a random identifier so that you can attach the result to an account later if you choose to create one. Nothing identifies you unless you do. Standard acquisition data (which link brought you here) may be recorded for reporting. Nothing is ever sent to HMRC.

Corrections

If you think a figure, threshold or source on this site is wrong or out of date, email hello@amireported.co.uk. We check every report against the GOV.UK source, correct anything that fails that check, and update the dated stamp on the affected page.

Quick answers

Does the check look up my data with HMRC?

No. It has no access to HMRC systems and cannot see whether a report about you was actually sent. It applies the published GOV.UK thresholds to the numbers you enter and tells you what would normally happen.

Is the answer generated by AI?

No. The verdict is computed by a deterministic rules engine: the same inputs always produce the same answer, every figure comes from a versioned rule set checked against GOV.UK, and every sentence comes from a reviewed phrase list with its source attached.

Do I need an account to run the check?

No. The free check asks for no signup, email or name. It stores the answers you entered, the verdict and the rule version under a random identifier, so you can attach the result to an account later if you want to.

What if a figure on this site is wrong?

Email hello@amireported.co.uk. Reports are checked against the GOV.UK source, corrections are made where the check fails, and the dated stamp on the affected page is updated.
