Do I Owe Tax?

See a sample report

This is what your report looks like, filled in for a made-up seller. Yours uses your own answers.

Meet Sam Example: sells on eBay and Vinted, buys stock to resell, and trades regularly enough that HMRC counts it as a business. The two pages below are the actual PDF Sam Example would get — the only thing changed is the watermark, so it can't be passed off as a real one.

Page 1 of the sample report: the verdict "You need to register and file a Self Assessment return", the reasons for it, the SA103S box-by-box figures, and the estimated Income Tax and Class 4 National Insurance due — all for Sam Example's made-up figures, watermarked "SAMPLE".Page 2 of the sample report: the key filing deadlines and a step-by-step walkthrough of registering for Self Assessment and getting a UTR, watermarked "SAMPLE".
