Rules and ethics
UK VAT rules for review incentives and UGC rewards explained
Ecommerce UGC rewards are a VAT question: HMRC treats vouchers, discounts and freebies given for reviews as supplies, so UK retailers must keep records.
What to take away
- Ecommerce UGC incentives are a VAT question because HMRC treats a reward for a review as payment for a supply, not a marketing cost.
- Single purpose vouchers are taxed at issue; multi purpose vouchers are taxed at redemption. That is the key trap.
- A voucher is a supply of its own; a discount reduces the taxable value; a freebie is a supply at open market value.
- Worked examples show the output tax a UK retailer owes on UGC and incentivised reviews.
- Keep the incentive terms, the reward value, the reviewer identity and the VAT calculation for each campaign.
- Review software should timestamp every incentive so the audit trail matches the VAT return.
Why HMRC treats review incentives as a VAT question
HMRC sees a barter: the reviewer supplies a service, the retailer supplies a reward. Both are supplies for VAT purposes when the retailer is VAT registered.
That matters because VAT is charged on the value of what the retailer gives up, not on the cash it spends.
The current VAT registration threshold is 90,000 pounds. The current standard rate is 20 per cent.
Business and self-employed guidance on GOV.UK points VAT registered traders to the rules for online businesses, including digital and distance selling. The starting point for any review scheme is whether the retailer is VAT registered and whether the incentive is consideration for a supply.
HMRC's own manual on business income and VAT is the reference behind that guidance. The principle is old: a supply for consideration includes non-cash consideration. A voucher, a discount code or a freebie all count.
Consumer law sits alongside the tax question. The Department for Business and Trade sets e-commerce and consumer policy, and that policy shapes what an incentive scheme may promise. A scheme that breaks consumer law can still create a VAT liability.
The Competition and Markets Authority (CMA) enforces consumer protection, including rules on incentivised reviews. The Advertising Standards Authority (ASA) covers endorsements. Neither replaces HMRC, but both affect how a scheme is documented.
VAT records matter because HMRC can check a scheme years later. If the reviewer was rewarded and the reward was not accounted for, the retailer owes the output tax plus interest.
A UK retailer running ecommerce UGC faces one set of VAT rules. VAT is UK-wide, so location changes the customer, not the liability.
Vouchers, discounts and freebies: the VAT treatment of each
The three common rewards behave differently for VAT. Getting the category right decides the output tax.
VAT treatment by reward type
Voucher (single purpose)
- VAT treatment
- Supply of voucher; VAT due when issued
- Who accounts for output tax
- Retailer issuing the voucher
Voucher (multi purpose)
- VAT treatment
- VAT due when voucher is redeemed
- Who accounts for output tax
- Retailer accepting the voucher
Discount code
- VAT treatment
- Reduces taxable value of later sale
- Who accounts for output tax
- Retailer making the sale
Free product
- VAT treatment
- Supply at open market value; output tax due
- Who accounts for output tax
- Retailer giving the freebie
Cash payment
- VAT treatment
- Consideration for a service; output tax due
- Who accounts for output tax
- Retailer paying the cash
Vouchers, discounts and freebies
| Reward | VAT treatment | Who accounts for output tax |
|---|---|---|
| Voucher (single purpose) | Supply of the voucher itself; VAT due when issued | Retailer issuing the voucher |
| Voucher (multi purpose) | VAT due when the voucher is redeemed | Retailer accepting the voucher |
| Discount code | Reduces the taxable value of the later sale | Retailer making the sale |
| Free product | Supply at open market value; output tax due | Retailer giving the freebie |
| Cash payment | Consideration for a service; output tax due | Retailer paying the cash |
VAT treatment of vouchers
A voucher is a supply in its own right. Many review rewards are multi purpose gift cards. The retailer issuing the card does not account for VAT at issue. The retailer accepting it accounts for VAT on the sale, and the card is treated as a means of payment.
A voucher given to a reviewer is consideration for the review. The retailer owes output tax on the value it gave up.
VAT treatment of discounts
A discount code is not a supply. It changes the price of a later sale. If a reviewer gets 20 per cent off, the taxable value of that sale is the discounted price, and VAT is due on that lower amount.
That is simple when the discount applies to a normal sale. It becomes a record-keeping question when the code is issued only in exchange for a review. The discount is still a reduction in consideration, not a separate reward.
The risk is treating a discount as a freebie. A discount reduces output tax; a freebie creates it. The two must be logged separately.
VAT treatment of freebies
A free product given for a review is a supply for no cash consideration. HMRC requires output tax on the open market value of that supply. The retailer cannot deduct the cost as if it were a pure marketing expense and ignore the output side.
Open market value is what a similar customer would pay. For an own-brand product, that is usually the normal selling price. For a third-party product bought for the campaign, it is the price the retailer would charge.
Freebie VAT rules also apply to services, such as a free subscription or a free listing.
A retailer that gives 500 free units at 20 pounds each has made supplies worth 10,000 pounds. At 20 per cent VAT, the output tax is 2,000 pounds, subject to the exact rate and any zero rating on the goods.
Worked example: a UK retailer paying for ecommerce UGC
A Manchester retailer sells homeware online and is VAT registered. It runs a UGC campaign: 40 customers each receive a 25 pound gift card for a photo and a short video. The gift card is multi purpose and can be used on any product.
The retailer issues 1,000 pounds of gift cards. No VAT is due at issue. When a customer redeems a card, the retailer accounts for VAT on the sale in the normal way.
If the customer buys a 30 pound item with a 25 pound card and pays 5 pounds cash, the taxable value is 30 pounds. VAT at 20 per cent is 6 pounds. The card is payment, not a discount.
Now change the reward to a free product. The retailer sends 40 units with a normal selling price of 25 pounds each. That is 1,000 pounds of supplies at open market value. Output tax at 20 per cent is 200 pounds, reported on the return for the period in which the goods were given.
The retailer must also decide whether the UGC is used in paid media. If the content is used in ads, the campaign cost is a separate marketing expense with its own input tax rules. The reward and the media spend are two different VAT events.
A finance team budgeting for this should separate the reward cost from the platform cost. The commerce reviews hidden costs article covers the budget lines that sit outside the reward itself.
The same logic applies to cash payments. If the retailer pays 25 pounds per review, that is 1,000 pounds of consideration for services. If the reviewer is not VAT registered, the retailer cannot reclaim input tax, but output tax is not usually due on a service bought from a non-registered supplier.
Worked example: incentivised reviews and the value of supply
A London cosmetics brand runs an incentivised review scheme. Customers who leave a verified review receive a 10 pound voucher for a single product line. The voucher is single purpose, so VAT is due when it is issued.
Gift card vs free product VAT
- 40customers rewarded
- 25pound gift card each
- 1,000pounds total gift cards
- 30pound item bought with card
- 6pounds VAT on sale
- 200pounds output tax on freebies
The brand issues 2,000 vouchers, each worth 10 pounds. The total value is 20,000 pounds. If the product line is standard rated at 20 per cent, the VAT on issue is 4,000 pounds. The brand accounts for that in the period of issue, even if no voucher is ever redeemed.
A scheme that assumes redemption will understate the liability.
Now consider a mixed scheme. The brand gives 1,000 multi purpose vouchers worth 10 pounds and 1,000 free products worth 10 pounds. The multi purpose vouchers create no VAT at issue. The free products create output tax on 10,000 pounds at open market value, so 2,000 pounds at 20 per cent.
The value of supply for an incentivised review is the reward, not the review text. HMRC does not tax the opinion. It taxes the consideration the retailer gives for the service of leaving a review.
That distinction matters when the review is negative. A retailer that rewards honest reviews, including negative ones, has still made a supply. The VAT treatment does not depend on the sentiment of the review.
The Digital Markets, Competition and Consumers Act 2024 bans fake reviews and makes incentivised reviews subject to transparency rules. A scheme that hides the incentive can breach consumer law and still owe VAT. The tax and the consumer rules run in parallel.
GOV.UK guidance on incentivised online reviews and endorsements tells businesses to disclose incentives clearly. That disclosure also helps the VAT record, because it identifies which reviews were rewarded.
Records a UK retailer should keep for HMRC
HMRC expects records that show what was given, to whom, when and why. A marketing spreadsheet is not enough. The records should tie to the VAT return.
- The incentive termswhat the reviewer was offered and what they had to do.
- The reward typevoucher, discount, freebie or cash, with the VAT category.
- The value of each reward, at open market value where no cash was paid.
- The reviewer identity or account reference, so the supply can be traced.
- The date of issue or supply, which sets the tax point.
- The VAT calculation and the period it was reported in.
- The disclosure wording used, to show the review was incentivised.
Keep the records for at least six years from the end of the accounting period. HMRC can open a compliance check later, and the burden is on the retailer to show the treatment was right.
A VAT account should reconcile the reward log to the return. If the log shows 1,000 pounds of freebies in a quarter, the return should show the corresponding output tax. A gap is the first thing a compliance officer will ask about.
UK GDPR and Data Protection Act 2018 rules apply to the reviewer data in the log. Keep the identity reference, but do not keep more personal data than the VAT record needs.
The Consumer Rights Act 2015 and the CMA's powers sit alongside the tax records. A retailer that can show a clean incentive log is better placed in both a VAT check and a consumer investigation.
Where review software should log incentives for VAT evidence
Review software sits between the customer and the finance system. If it captures the incentive at the point of collection, the VAT record is almost automatic. If it does not, the finance team rebuilds it later.
A good platform should record the reward type, the reward value, the date and the campaign reference on the same record as the review. That gives HMRC a single audit trail from review to VAT return.
It should also flag single purpose vouchers separately from multi purpose vouchers. The tax point differs, and the software should not treat them as one category.
For freebies, the software should store the open market value used, not just the cost price. The cost price is an input figure; the open market value is the output figure HMRC taxes.
For discounts, the software should link the code to the later sale so the reduced taxable value is visible. A discount that is never linked to a sale is a record-keeping gap.
When comparing platforms, the VAT logging matters as much as the review collection. The commerce reviews pricing models article sets out how vendors charge for that functionality.
A finance team should ask three questions of any vendor. Does the platform timestamp the incentive? Can it export the reward log by VAT period? Does it separate vouchers, discounts and freebies?
If the answer is no, the finance team will keep a parallel log. That is workable, but it adds cost and risk. The commerce reviews costs and pricing article covers the budget effect of those manual controls.
HMRC does not require a specific software format. It requires records that are accurate, complete and retrievable. A review platform that produces that export is doing VAT work, whether or not it is sold as a VAT tool.
The practical test is simple. If HMRC asked for the reward log for a quarter, could the retailer produce it in an hour? If not, the software is not yet doing its job.
