💡 Tips
⚠️You must register for Self Assessment by 5 October after the tax year ends. Register on gov.uk →
⚠️Because eBay has reported your sales to HMRC, filing a Self Assessment return (even if you owe nothing) is the safest move to avoid an investigation.
✅Keep records of every sale: date, amount, what you sold, and original purchase price. HMRC can investigate up to 4 years back.
