Why you are taxed on profit not Stripe payouts, supplier and advertising costs, the trading allowance, import VAT and the GBP 90k threshold, and MTD explained for UK dropshippers.
Dropshipping has a tax problem that almost no other trade shares: the money flowing through your payment processor bears almost no relationship to your taxable profit. A store can run GBP 120,000 through Stripe in a year, hand most of it straight back to AliExpress suppliers and the Facebook ad auction, and end up with GBP 9,000 of actual profit. The single most common, and most expensive, mistake new dropshippers make is confusing that Stripe balance with what they owe HMRC. You are taxed on profit, and profit in dropshipping is a thin slice of a very large gross.
The second defining feature is that you never touch the goods. Your supplier ships directly to the customer, which keeps your costs simple (no warehouse, no stock to value) but introduces a VAT wrinkle that does not exist for an ordinary reseller: because the goods are usually imported, you can be liable to charge UK VAT on low-value consignments from your very first sale. Get those two ideas right, profit not turnover, and the import-VAT trap, and dropshipping tax becomes manageable.
Some online sellers genuinely sit in a grey zone between hobby and trade. Dropshippers do not. By definition you have set up a store, sourced products, and run paid advertising with the intention of making a profit. That is unambiguous trading under HMRC's badges of trade: a clear profit motive, organised and repeated activity, and goods acquired specifically to sell on. There is no "I was just clearing out my loft" defence here. From the moment your gross sales pass the GBP 1,000 trading allowance, you must register for Self Assessment.
As a sole trader you pay Income Tax and National Insurance on profit. For 2025/26 the personal allowance covers the first GBP 12,570, then it is 20% to GBP 50,270, 40% to GBP 125,140 and 45% above. Class 4 NIC is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above, with Class 2 NIC collected through the return.
Scottish dropshippers pay Scottish Income Tax on their profit, across six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, while National Insurance remains UK-wide. Welsh taxpayers have a C-prefixed code at rates that currently match England and Northern Ireland. The location of your customers does not change which rates apply to you; your own residence does.
Many dropshippers run the store alongside a full-time job, so the profit stacks on top of employment income and is taxed at the marginal rate. The multiple income calculator shows the combined position, and the sole trader tax calculator handles the store in isolation from a profit figure.
An expense is allowable when incurred wholly and exclusively for the business. The dropshipper's list is short on physical items and heavy on platform and advertising costs.
| Expense | What qualifies | Notes |
|---|---|---|
| Cost of goods sold | What you actually pay suppliers (AliExpress, CJ, Zendrop, agents) for orders fulfilled | Your principal direct cost; matches each order to a supplier charge |
| Advertising | Facebook, TikTok, Google and Snapchat ad spend, influencer fees, UGC creators | Usually the single largest expense; keep every ad-platform invoice |
| Platform and store fees | Shopify or WooCommerce subscription, themes, domain | Recurring deductible costs of running the store |
| Transaction fees | Stripe, PayPal, Shopify Payments and currency-conversion charges | Deducted by the processor; declare gross sales and claim fees separately |
| Apps and software | Product importers, AutoDS, order trackers, email and SMS tools, analytics | Monthly SaaS costs, fully deductible |
| Product samples | Test orders you buy to vet suppliers and shoot content | Allowable where genuinely for the business |
| Home-working costs | Flat-rate working-from-home allowance, or a fair proportion of broadband, heat and light | Most dropshippers run the store from home |
| Professional fees | Accountancy, bookkeeping, MTD-compatible software | Fully deductible |
For most stores, advertising is 30% to 60% of gross sales. It is also the expense HMRC is most likely to want evidenced if it ever queries a return, precisely because it is large. The ad platforms produce monthly billing summaries; download and keep them. A dropshipper who declares GBP 80,000 of sales but cannot evidence the ad spend behind it risks being taxed as though most of that GBP 80,000 were profit. Connect your ad accounts and Shopify to your bookkeeping from day one rather than reconstructing the year from card statements.
This is where dropshipping diverges sharply from selling your own stock. When goods are imported into the UK in a consignment with an intrinsic value of GBP 135 or less, and they are sold to a UK consumer, the seller is generally required to charge UK VAT at the point of sale and account for it to HMRC, regardless of whether the seller is over the GBP 90,000 registration threshold. In practice this means a dropshipper sending GBP 20 phone cases from China to UK buyers can have a VAT obligation from the first order.
Where the goods are sold through an online marketplace (rather than your own Shopify store), the marketplace is often made responsible for that VAT instead. But a dropshipper selling direct from their own domain cannot assume someone else is handling it. This is a genuinely complicated area, and the rules differ for consignments above GBP 135, where import VAT and potentially duty arise at the border instead. If a meaningful share of your sales are low-value imports to UK customers, take advice early; getting it wrong accrues quietly and is expensive to unwind.
Separately from the import rules, you must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period. The test is on gross sales, not profit, so a thin-margin store hits it on revenue long before it feels "big". Once registered you charge 20% VAT on standard-rated UK sales, can reclaim VAT on UK costs, and file VAT returns digitally under MTD for VAT. Model the margin impact with the VAT calculator before you reach the threshold, because adding 20% to your prices or absorbing it from a slim margin both hurt.
Take a sole-trader dropshipper running a single Shopify store with GBP 70,000 of gross sales in 2025/26, run from home alongside other income that has used the personal allowance.
Gross sales: GBP 70,000
Allowable expenses:
Taxable profit: GBP 70,000 minus GBP 58,700 = GBP 11,300
Income Tax (personal allowance used by other income): GBP 11,300 at 20% = GBP 2,260
Class 4 NIC: GBP 11,300 at 6% = GBP 678
Total tax and NIC: GBP 2,938. The lesson is stark: GBP 70,000 ran through the store, but the tax bill is built on GBP 11,300 of real profit. The same store with no evidence for its GBP 24,000 of ad spend could be argued into a far higher assessment. Run your own figures through the sole trader tax calculator before you file.
In dropshipping, your Stripe balance is not your income and your turnover is not your profit. Tax follows the thin margin left after suppliers and ads, so the discipline is simply evidencing every cost.
Making Tax Digital for Income Tax Self Assessment replaces the annual return with quarterly digital submissions and a year-end finalisation:
The threshold uses gross sales, not profit, which is brutal for dropshippers: a store turning over GBP 60,000 on a 12% margin takes home around GBP 7,000 but is squarely in the first MTD wave. For you, MTD means keeping digital records of sales, supplier costs and ad spend throughout the year and connecting Shopify, Stripe and your ad accounts to MTD-compatible software, rather than rebuilding everything from a spreadsheet each January. The MTD for sole traders guide walks through the quarterly process.
Treating the Stripe balance as income. You are taxed on profit after suppliers, ads and fees, not on money that merely passed through your account.
Not evidencing ad spend. Advertising is your biggest deduction and the most likely to be queried. Save every ad-platform invoice.
Ignoring import VAT on low-value goods. Selling imported items of GBP 135 or less to UK consumers from your own store can create a VAT obligation from the first sale.
Confusing turnover with the MTD test. The GBP 50,000 threshold is gross sales, so thin-margin stores are caught earlier than their take-home suggests.
Forgetting payments on account. A first balancing bill over GBP 1,000 triggers two advance payments toward next year, half in January and half in July.
