Quick answer
Yes, Whatnot sales are taxable in the UK when you buy or make stock to sell for profit. Tax applies to trading profit, not the amount paid out by the app. Whatnot may report seller information to HMRC, while tips, paid breaks and promotional giveaways each need accurate records and their own tax treatment.

How Whatnot seller tax UK works
Yes, if your Whatnot activity is a trade. Buying cards, collectables or other stock for resale normally creates taxable trading income; selling a few possessions you already owned usually does not. The £1,000 trading allowance applies to gross trading income across all of your small trades, not separately to each Whatnot account.
It may. Whatnot is the kind of digital marketplace covered by UK platform-reporting rules, so it can collect seller identity and transaction data and report relevant sellers. Reporting is not the event that creates tax: your activity can be taxable even below a platform reporting exclusion. Compare your annual statement with your own bank and inventory records.
Usually, yes, where they form part of the business. Free giveaway stock is normally an advertising or promotion cost rather than sales income, provided the cost is wholly for the trade. Money received for card or box break places is trading turnover. Record the full customer receipts, stock used, refunds and platform deductions separately.
They can raise regulatory questions where customers pay for a chance-based allocation, although the exact answer depends on how the break is designed. Tax treatment does not make a promotion legally compliant. Take specialist gambling-law advice before running chance-based paid breaks, and do not assume a platform feature removes UK legal obligations.
Record bulk purchases as stock and allocate a reasonable cost to the items sold. Under the cash basis, stock costs are generally recognised when paid, subject to the detailed rules, but good unit-level records still show whether a stream was profitable. Keep supplier invoices, break sheets, grading fees and evidence for mixed lots.
Usually, to the extent it is used for the Whatnot trade. Cameras, lights, microphones, mounts and dedicated streaming software can be allowable. Where equipment also has personal use, claim only a reasonable business proportion. Expensive or long-lasting assets can need different tax treatment depending on the accounting method used.
The starting point for Whatnot seller tax UK is the difference between gross receipts and taxable profit. Gross receipts include money and non-cash value earned through the activity. Profit deducts qualifying business costs. Platform reporting is an information rule; it does not replace this calculation.
Use the figures in the 2026/27 tax tools only after income and costs have been classified correctly. The £1,000 trading allowance, £90,000 VAT registration threshold and Making Tax Digital entry points apply across the relevant business, not once for every app.

Expenses
Whatnot seller tax UK: allowable costs
A cost must relate to the trade, and mixed personal use needs a fair restriction. Keep the invoice and note the business purpose.
Usually claimable
- Cards and collectables bought for resale
- Whatnot platform and payment fees
- Postage, sleeves, cases and labels
- Business-use cameras, lighting and microphones
- Grading and authentication directly linked to stock
- Giveaway stock used wholly to promote streams
Usually not claimable
- Personal collection items without evidence of business transfer
- Private gaming or hobby purchases
- The personal share of dual-use equipment
- Fines or penalties
- Customer payments omitted because the platform retained fees
Use the creator expenses checklist to organise evidence before filing.
How HMRC’s rules apply to whatnot sellers
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
- Stock bought for resale, packaging and marketplace selling fees
- Business postage, payment processing and product photography costs
- The business share of storage and equipment, subject to the accounting basis
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.

Structure
Sole trader or limited company?
Start with the simplest structure that reflects ownership and risk. A limited company is not automatically more tax-efficient; compare ongoing profit, cash needs, administration and commercial exposure.
