eBay Dropshipping Tax UK 2026: VAT, Income Tax & What You Owe
Tax is where a lot of new sellers get caught out. Here is a plain-English overview of the rules that apply to UK eBay sellers in 2026 — what you can earn before declaring, when VAT kicks in, and what HMRC already knows.
This is general information, not financial or tax advice. Rules and thresholds change — always confirm current figures on GOV.UK and speak to a qualified accountant about your situation.
The £1,000 Trading Allowance
You can earn up to £1,000 in gross trading income per tax year without registering for Self Assessment. This is the trading allowance. The moment your total sales (not profit) cross £1,000 in a tax year, you need to register with HMRC and declare. For anyone running eBay as a business, you will pass this almost immediately.
Income Tax & Self Assessment
Once over the allowance, you register for Self Assessment and pay income tax on your profit — sales minus allowable costs (stock, eBay fees, postage, packaging, software, a portion of home and internet use). You pay tax at your normal income tax band on that profit, plus Class 4 National Insurance once profits pass the relevant threshold.
Keep every figure. Good records are the difference between paying tax on profit and accidentally paying tax on turnover. Our fees guide and margins guide help you track the numbers that feed your return.
The £90,000 VAT Threshold
If your taxable turnover passes £90,000 in any rolling 12-month period, you must register for VAT with HMRC within 30 days. This is turnover, not profit, and it rolls forward every month — so check the last 12 months at the end of each month, not just at year end. The deregistration threshold sits at £88,000. These figures have applied since April 2024.
VAT registration is a big step for a dropshipper because you then charge 20% VAT on sales, which either eats your margin or raises your prices. Plan for it before you get there.
Making Tax Digital (From April 2026)
From April 2026, sellers with combined self-employment and property income above £50,000 must follow Making Tax Digital for Income Tax — keeping digital records and submitting quarterly updates to HMRC using compatible software, instead of one annual return. The threshold steps down to lower income levels in later years, so it is worth getting digital records in place early.
HMRC Already Sees Your Sales
This is the part many sellers miss: online marketplaces including eBay now report seller data to HMRC under digital platform reporting rules. If you sell above the reporting limits, HMRC receives your sales figures directly. "They will never know" is no longer a strategy — the data is shared automatically. Declaring properly is the only safe route.
Selling to the EU & Other Markets
Expanding to Germany, France, or other markets brings extra rules — notably EU VAT and the €10,000 cross-border B2C threshold, plus import VAT and IOSS. Cross-border tax is complex; get specialist advice before you scale into new countries.
