UK ecommerce and marketplace sellers (Amazon, eBay, Etsy, Shopify): tax, VAT, platform reporting and seller accounts
A marketplace seller accountant owns the tax layer that SaaS tools and generalist firms cannot credibly cover: the gross-sales VAT threshold the platform payout hides, deemed-supplier and establishment status, VAT on overseas marketplace fees, cross-border IOSS and OSS obligations, and settlement reconciliation that turns platform reports into accurate accounts. For general ecommerce accounting see hollowaydavies.co.uk; we handle the multi-platform seller layer.
Amazon FBA and FBM sellers, Shopify DTC store owners, eBay, Etsy, TikTok Shop and Vinted marketplace sellers, and dropshippers. Many clients sell across three or more platforms simultaneously. Select your model for the detail that applies.

Most sellers reach out at one of these six points. Each involves money that a generalist accountant will not handle correctly without seller-specific knowledge.
| Seller tax event | Key figure or date | Common mistake |
|---|---|---|
| VAT registration | £90,000 gross sales (rolling 12 months) | Measuring against net payout, not gross sales |
| Platform reporting | From 1 January 2024, first reports January 2025 | Treating the 30-sale/£1,700 reporting exclusion as a tax threshold |
| MTD ITSA (sole traders) | £50,000 from 6 April 2026; £30,000 from 6 April 2027 | Assuming it applies only to landlords or larger businesses |
The £90,000 VAT registration threshold is measured on gross taxable sales, not the net payout Amazon or Etsy deposits after fees. Sellers who watch their bank balance against the threshold will breach it without realising. There is also a forward-look test: registration is required if turnover is expected to exceed £90,000 in the next 30 days alone. This is the most common late-registration trap for marketplace sellers. VAT compliance service →
Where a seller is not established in the UK, the marketplace is the deemed supplier and accounts for UK VAT on those sales. UK-established sellers are outside that mechanism and remain liable themselves. Establishment status is the single most consequential VAT fact for any marketplace seller. HMRC actively challenges weak establishment claims. Deemed-supplier guide →
Marketplace, advertising and software fees billed from abroad are reverse-charge services under Notice 741A. You self-account for the VAT, and crucially that reverse-charge value counts toward the £90,000 registration threshold. A sub-threshold seller buying large volumes of overseas platform and ad fees can tip over the threshold faster than gross sales alone would suggest. Fees VAT guide →
From 1 January 2024, digital platforms must report seller income to HMRC under the OECD model rules, with first reports due in January 2025. The platform-reporting exclusion (below 30 sales and approximately £1,700 in the period) determines whether the platform reports you. It is not a tax-free threshold. Tax follows trading status. Ignoring an HMRC nudge letter is not a strategy. HMRC letter service →
An Amazon settlement report is not an accounting document. It mixes gross sales, FBA fulfilment fees, referral fees, advertising costs, reimbursements and loan repayments in a single net figure. Bookkeeping built from bank deposits misstates revenue, understates expenses and produces a VAT return that does not reconcile to actual sales. Shopify payouts add multiple gateways each settling on different cycles. Reconciliation service →
Sole-trader sellers with qualifying income above £50,000 must keep digital records and file quarterly updates from 6 April 2026. The threshold drops to £30,000 from 6 April 2027 and to £20,000 from 6 April 2028. The sole-trader seller cohort is hit first. For generic MTD mechanics and registration see hollowaydavies.co.uk; we handle the seller-specific picture.
The UK rules on selling goods to overseas buyers changed fundamentally after 2021. The deemed-supplier mechanism, the £135 import rule for direct-to-consumer dropship, IOSS for EU sales and postponed VAT accounting for importers are all live seller obligations that most content treats at surface level. Our VAT cluster covers each in the depth a working seller actually needs.
Note: IOSS and OSS cross-border figures are EU law; our guides cite the correct sources at each decision point rather than asserting figures from the wrong jurisdiction.
Scenario and compliance tools built for UK online sellers. No sign-up, no data stored. Model your take-home after platform fees and tax, track your rolling gross sales against the VAT threshold, or compare sole trader and limited company outcomes at your income level.
Data for UK marketplace sellers: how many SIC 47910 online retail companies sit on the Companies House register, how many have dissolved, quarterly formation and dissolution churn, survival by formation-year cohort, and the ONS internet share of retail sales as a demand-side anchor. It measures the incorporated layer only, since marketplace-only sole traders never reach the register. An evidence base for the seller community, not a marketing piece.
A generalist firm prepares your accounts and files your returns. They will not, by default, know that your VAT registration threshold is on gross sales before the platform takes its fees, or that marketplace fees billed from abroad count toward that threshold under the reverse charge, or that your settlement report is not an accounting document.
SaaS tools (A2X, Link My Books and similar) automate settlement reconciliation well. They sell software, not tax positions. They cannot assess your establishment status, advise on the deemed-supplier mechanism, or tell you whether your cross-border fulfilment creates a VAT registration obligation in another jurisdiction.
Seller-specialist accounting means the VAT registration decision, the scheme choice, the cross-border structure and the annual accounts are all built around how platforms and fulfilment models actually work, not a standard compliance template with an ecommerce label.
An HMRC letter about online sales
Platform reporting data goes to HMRC from January 2025. Sellers whose returns do not match the platform data receive nudge letters. Ignoring them escalates to formal checks with higher penalties.
Approaching or over the VAT threshold
The threshold is on gross sales. Sellers who discover they have been above it for months, measured correctly, need registration, a VAT scheme decision and potentially a back-dated return before HMRC finds the gap first.
Expanding to EU customers or FBA distribution
Cross-border fulfilment adds establishment-status questions, potential country-level registration obligations and the IOSS intermediary requirement for GB sellers. The consequences of getting it wrong land on the seller.
Not legally, but the seller-specific tax layer is routinely missed by generalist firms. VAT registration on gross sales (not payout), deemed-supplier and establishment status, reverse-charge fees, settlement reconciliation and cross-border obligations are all specialist territory. A generalist prepares standard accounts and returns; they do not, by default, handle these.
Gross sales. The £90,000 VAT registration threshold is measured on taxable turnover, which for marketplace sellers is the gross selling price before the platform deducts fees and pays out. Monitoring your bank balance or settlement payouts against the threshold understates your taxable turnover and causes late registration.
It depends on establishment status. Where you are not established in the UK and sell through an online marketplace to UK customers, the marketplace is the deemed supplier and accounts for UK VAT. UK-established sellers remain liable themselves and are outside the deemed-supply mechanism. Establishment status is the key fact.
Yes. Digital platform reporting rules took effect on 1 January 2024 and platforms report seller income to HMRC annually from January 2025. The exclusion for sellers below 30 transactions and approximately £1,700 is a reporting exclusion, not a tax threshold. Tax liability follows trading status regardless of whether the platform reports you.
Marketplace and advertising fees billed from abroad are reverse-charge services under Notice 741A. You self-account for the VAT on your VAT return. The reverse-charge value counts toward your £90,000 VAT registration threshold, which is the classic surprise trigger for sub-threshold sellers with high ad spend.
Yes. Most of our seller clients sell across two or more platforms. The challenge is that each platform settles differently, applies fees differently and may have different VAT implications. We work across Amazon FBA and FBM, Shopify, eBay, Etsy, TikTok Shop, Vinted and dropship models.
It depends on your income level and extraction plans. Incorporation can be tax-efficient above certain profit levels when salary and dividends are structured correctly, but adds compliance cost and complexity. Use our sole-trader-vs-Ltd calculator for a numbers comparison, and see hollowaydavies.co.uk for the generic incorporation picture. We advise on the seller-specific structuring.
