A bonus can move through marketing, a supplier’s wallet and several games before it reaches the tax return. With Remote Gaming Duty already at 40% and new rules proposed for April 2027, operators need to test whether the evidence survives every handover.

Can finance follow one free spin all the way from the campaign code to the tax return? If the answer depends on a developer remembering how the wallet worked, the audit trail is already too fragile.

The UK government’s 28 October proposal gives operators a deadline to work towards. HMRC wants to replace the existing freeplay provisions with rules for “restricted play” from 1 April 2027. Its stated aims include reducing disputes and protecting revenue; it forecasts no additional Exchequer yield from the measure. ¹

There is now draft legislation to test against: clause 82 of the Finance Bill introduced on 4 November. It covers operator-funded money restricted to remote gaming, waived gaming payments, prizes and tournaments. These remain proposed rules, not law already in force. ²

The CFO’s problem: a data error can become a cash cost

Remote Gaming Duty is already 40%, following the increase from 21% on 1 April 2026. The proposed 2027 measure concerns what enters the calculation, rather than another increase in that rate. ³

That makes classification expensive to get wrong. If a data error adds £100,000 to an operator’s positive taxable profit, the additional duty at 40% is £40,000, all else equal. This is an illustration of exposure, not an estimate of industry overpayment.

But a promotional stake does not become tax-free simply because no cash changed hands. HMRC’s current guidance counts qualifying initial freeplay at its undiscounted value when used. It excludes qualifying re-wagered winnings and allows eligible prize deductions when the relevant conditions are met. ⁴

Counting excluded re-wagers as fresh taxable stakes, or missing an eligible prize deduction, can inflate the bill. The opposite mistakes can understate liability. A campaign’s headline “bonus cost” or gross gaming revenue (GGR) figure cannot settle those classifications. Finance needs a reconciliation from the commercial report to the RGD computation.

A judgment shows why the actual offer matters

In Jumpman Gaming Ltd v HMRC, decided on 25 September 2026, the Upper Tribunal examined a welcome promotion with an initial Mega Reel spin and further free spins won on other games. It left undisturbed the finding that the initial spin did not waive a payment otherwise required, and held that the further spins fell within the statutory exclusion. The assessments under appeal therefore fell to nil. ⁵

The result turned on the arrangements and legislation before the tribunal. It was no blanket exemption for free spins. A displayed spin value and an accounting entry could not, by themselves, establish a price the customer would otherwise have paid.

The operational lesson is straightforward: preserve the offer the player actually received. A judgment about an earlier period, HMRC guidance and a future legislative change cannot simply be substituted for one another.

Three outputs need one explainable history

HMRC Notice 455a requires records supporting duty returns, including promotional offers, their uptake and use, and the value had full payment been required. Its retention requirements vary by record type. ⁴

The Gambling Commission’s account-information standard serves a different audience. Customers must have access to at least three months of gambling and account history without contacting the operator, and at least 12 months on request, with appropriate bonus and product-transfer information. ⁶

The Competition and Markets Authority’s promotions guidance also says customers should be able to distinguish their own money from bonus funds and leave a promotion with their remaining deposit and winnings from play with it. ⁷

The tax return, customer statement and promotional terms are different outputs. An operator should be able to explain how the same events produced all three, including any differences in classification.

Can your platform supplier produce the evidence?

If a third-party player account management (PAM) platform controls the wallet and bonus engine, finance depends on the records that supplier captures and makes available. The operator’s integrations and tax classifications matter too. A dashboard total is not a transaction history.

Outsourcing leaves the operator responsible for its licensing obligations. Gambling Commission code 1.1.2 requires relevant third-party contracts to secure information reasonably needed to meet the licensee’s obligations to the Commission. That is a licensing requirement, separate from HMRC’s tax rules. ⁸

Before April 2027, review the PAM agreement alongside a real data export. The useful questions are concrete:

• Can the records be joined? Connect campaign, account, wallet and game-round identifiers, including the source of funds and changes to withdrawal restrictions.
• Can an exception be reconstructed? Preserve reversals, manual adjustments and the terms and rules in force at the time. Assign an owner and deadline for missing events.
• Will the evidence remain accessible? Check usable exports, access for independent review, appropriate retention and continued access after a supplier change.

These are practical contract checks, not newly prescribed statutory clauses. A supplier’s promise to “support compliance” should become a demonstrable export that finance can reconcile.

The journey of a free spin

Consider a promotion whose winnings remain restricted until its wagering conditions are met. This five-step illustration shows the evidence to connect; it is not a prescribed reporting format or a conclusion that every bonus receives the same tax treatment.

The key handover is between steps three and four: a win appearing on screen does not necessarily mean the customer can withdraw it. Finance needs the event that changes the customer’s rights, as well as the amount.

Stress-test the difficult transactions

A clean example proves little about exceptions. Use the following hypothetical cases to test whether the records can support a decision.

1. Restricted play wins more restricted play

The draft Bill ties an exclusion to the origin and permitted use of the winnings, including whether the player was entitled to an alternative benefit usable outside remote gaming. A generic “bonus” label cannot answer that question. ²

Compare the originating game event, reward options, accepted terms and subsequent use. Recording only the option the player selected can lose evidence of an alternative they were entitled to choose.

2. Cash and restricted winnings share a wallet

Existing section 159A(6) of the Finance Act 2014 gives mixed funds a specific ordering rule. A payment is treated as coming from excluded winnings only to the extent it exceeds the other funds. It is not a simple proportional split. ⁹

Finance therefore needs the relevant balances before the payment and the basis for classifying the winnings. Check that the wallet export preserves both. A customer-facing allocation and a tax classification may differ; the reconciliation should explain why.

3. An interrupted game produces a credit

A reversed stake, a contractual prize and a goodwill payment can all look like a “refund” in a service log. Keep their meanings separate.

Clause 82 proposes conditions for prize treatment, including published game rules and specified circumstances for returned gaming payments following interruption or termination. It does not make every customer credit deductible. ²

The Gambling Commission’s interrupted-gambling standard separately addresses fair treatment and recovery, distinguishing completed outcomes, interrupted single-stage games and games that should be restored. ¹⁰

Join the original debit, interruption log, game state, applicable rules and eventual credit. Customer service can then explain the remedy while finance assesses its tax treatment. Tournament promotions need a separate check against the Bill’s participation and prize provisions.

A tax classification cannot approve the offer

The promotion must also satisfy the rules governing what customers may be offered. The Gambling Commission’s current rewards-and-bonuses code caps wagering requirements at ten times the bonus amount and prohibits mixing gambling product types within an incentive. ¹¹

Its guidance distinguishes that prohibition from an incentive giving customers unrestricted choice of product category for bonus credit. The qualifying activity and reward still need to be examined together. ¹²

CAP guidance requires significant promotional conditions to be clear and prominent where omission could mislead, with full terms readily accessible. An accurate back-office record cannot repair a misleading customer promise. ¹³

Keep the tax, licensing and advertising assessments distinct, but attach them to the same version of the offer. One “compliant bonus” flag is too blunt to explain all three.

Run the reconciliation now

Choose a completed campaign and bring together marketing, finance and the person responsible for the PAM, involving the supplier where needed. Start with marketing’s campaign code. Match it to wallet and game events, then to finance’s GGR report and the adjustments feeding the RGD calculation.

Include a mixed-funds payment, a release of restricted winnings, an expired bonus and an interrupted game where those events occur. Ask someone outside the campaign team to reconstruct each case from the retained records.

Every unexplained difference needs an owner, a correction and a repeat test. If the missing evidence sits with a supplier, turn that gap into a contractual deliverable with an agreed date. Add the final legislation to the test once enacted.

Do not wait for April 2027 to discover that the campaign code disappears before the tax report. Trace it now. A matching monthly total is useful; an explainable transaction history is what lets the CFO defend the number.
