VAT and tax basics for UK resellers

Reselling is a trade. Once you are buying stock with the intention of selling it at a profit, HMRC treats the activity as a business regardless of how small it is or whether you have registered anything.

Sole trader or limited company

Most resellers start as sole traders because registration is simple and the reporting burden is light. A limited company adds administration and filing requirements, but separates business liability from personal assets and can become more tax-efficient at higher profit levels. The switching point depends on your profits and personal circumstances, which is exactly the sort of question an accountant answers cheaply and quickly.

When VAT registration comes in

VAT registration becomes compulsory once taxable turnover passes the UK registration threshold on a rolling twelve-month basis. Turnover means sales, not profit — a point that catches out resellers who look at their margin and assume they are far below the line. Check the current threshold on GOV.UK, as it is reviewed periodically.

• Registration is based on rolling twelve-month turnover, not your financial year
• You can register voluntarily below the threshold if reclaiming input VAT is worthwhile
• Buying from VAT-registered suppliers means you receive a VAT invoice you can reclaim against once registered
• Some second-hand goods may be eligible for a margin scheme — worth asking about specifically

Records to keep from day one

1. 1Every purchase invoice, including delivery charges
2. 2A record of what each lot contained and what it sold for
3. 3Marketplace fee statements, downloaded monthly rather than reconstructed later
4. 4Mileage and vehicle costs where you collect stock yourself
5. 5Storage, packaging and postage costs

Marketplace reporting

UK digital platforms report seller information to HMRC where sellers exceed reporting thresholds. This is not a new tax — it simply means marketplace activity is visible. Sellers who have kept clean records have nothing to do differently; sellers who have not are usually the ones who find it stressful.
