Quick answer

Affiliate marketing tax UK rules treat commission from Amazon Associates, Awin, LTK and every other network as trading income, declared gross with network fees claimed as costs. Ad spend, tracking software, hosting, tools and outsourced content are deductible, and overseas networks can change the VAT treatment once you register.

Tax explained

How affiliate marketing tax UK works

Affiliate marketing is a trade for tax purposes, whether the commission comes from Amazon Associates, Awin, LTK or a direct merchant deal. Commission is taxable when earned, and you declare the gross amount the network reports, claiming network fees, payment platform charges and currency conversion as costs rather than netting them off.

The deductible side is usually substantial: advertising spend, hosting and domains, tracking and analytics software, landing page builders, email platforms, outsourced content and link building, freelancers, and the business share of a home office.

Reconciliation is the real work. Networks report on their own cycles, hold payments until a threshold clears, and reverse commission after refunds. We match network reports to bank receipts monthly so the annual figure is defensible and you can see true margin by campaign.

Sole trader profits are taxed at Income Tax rates with Class 4 National Insurance on top. Because affiliate income is volatile, we set a reserve as a percentage of each payout and review it quarterly rather than guessing annually.

VAT deserves early thought. Gross commission counts towards the registration threshold, and high-turnover media buyers can pass it quickly. Registration lets you reclaim VAT on advertising and software, and commission from overseas business merchants such as many US networks is often outside the scope of UK VAT.

US-based platforms and networks will usually ask for a W-8BEN before paying you, which stops US withholding tax being deducted under the UK-US treaty — it does not change what you owe HMRC. LTK, ShopMy and similar storefront platforms pay out on their own schedules, and their commission is taxed exactly like any other affiliate income.

Finally, keep the business tidy: a separate bank account, a card used only for ad spend, downloaded network statements each month, disclosure records for ASA compliance, and supplier invoices filed. That is what turns a messy multi-network year into a straightforward return.

Expenses

Affiliate marketer expenses: website, hosting and ad spend that count

Allowable expenses for affiliate marketers UK are usually dominated by advertising spend, tracking software and outsourced content, all claimable in full alongside network and payment processing fees. Yes, website and hosting costs are fully deductible, along with domains, themes and landing page tools, since they are the infrastructure the whole trade runs on. What can't be claimed is anything bought through your own affiliate links for personal use. Because gross commission counts towards VAT registration, tracking spend accurately also protects your threshold monitoring and your Self Assessment for creators filing.

Usually claimable

  • Website, hosting, domains and landing page tools
  • Advertising and media buying spend
  • Tracking, analytics and attribution software
  • Outsourced content, writers and link building
  • Email marketing platforms
  • Laptop and equipment (business share)
  • Business share of home office and broadband
  • Payment platform and conversion fees
  • Accountancy, insurance and legal review
  • Industry events and training relevant to the trade

Usually not claimable

  • Personal purchases made through your own links
  • Entertaining network or merchant contacts
  • Everyday clothing
  • Personal share of household bills
  • Fines and penalties
  • Speculative investments unrelated to the trade

Log ad spend and network fees campaign by campaign using the creator expenses checklist, so margin by offer is always visible.

How HMRC’s rules apply to affiliate marketers

If you are self-employed

Self-employed costs must be incurred wholly and exclusively for your trade. If you use the £1,000 trading allowance, you cannot also deduct actual expenses against that same income. Equipment treatment depends on cash basis or traditional accounting.

If you run a limited company

A limited company deducts costs incurred wholly and exclusively for its business. Equipment may need capital allowances rather than an immediate expense deduction. Personal use or company-paid private costs can create a taxable benefit or director’s loan entry; company ownership is not a blanket deduction.

For separable mixed-use costs, such as a phone bill, claim only the identifiable business proportion and keep evidence. This does not make ordinary clothing or every dual-purpose purchase deductible. A receipt alone does not prove a business purpose: retain the brief, invoice or usage record too.

Costs to review for your work

  • Business-use cameras, lighting, audio equipment and editing software
  • Editors, thumbnail designers, virtual assistants and licensed music
  • Travel to business shoots and the evidenced business share of home-working costs

Everyday clothing, ordinary grooming, personal meals, private gaming and fines are generally not deductible. Qualifying costumes or protective clothing and business-travel subsistence have different rules. Client entertaining is generally disallowed. Receiving a product from a brand does not automatically create an expense: record the income treatment separately and deduct only an allowable business cost.

Keep records alongside our creator expenses checklist, or discuss your costs with our bookkeeping team.

Structure

Sole trader or limited company?

Content affiliates with modest profit usually stay sole traders. Media buyers with large spend, or affiliates holding several sites, often prefer a limited company: it separates ad account liabilities from personal finances, retains working capital for spend, and makes a future site sale cleaner to structure.

VAT & MTD

VAT and Making Tax Digital

VAT

Gross commission counts towards the VAT registration threshold, so turnover can pass it long before profit looks big. Registration is frequently a net gain for media buyers because VAT on advertising and software becomes reclaimable, and commission billed to overseas business merchants is generally outside the scope of UK VAT.

Registration threshold: £90,000 · Deregistration: £88,000

Making Tax Digital

Making Tax Digital qualifying income is gross commission, not profit after ad spend. Affiliates with thin margins and high turnover are therefore often in scope from the earliest threshold date, so check April 2026 and 2027 against gross figures.

  • April 2026: qualifying income above £50,000
  • April 2027: qualifying income above £30,000
  • April 2028: qualifying income above £20,000
