RGD at 40% Plus Corporation Tax at 25%: Modelling the True UK Operator Tax Burden

From 1 April 2026, remote gaming operators serving UK-resident players account for Remote Gaming Duty at 40% of gross gaming yield, administered by HMRC under the Finance Act 2014, Part 3 Chapter 3. Corporation Tax at the 25% main rate then applies to the taxable trading profit that remains. Because RGD is a deductible trading expense for the purposes of Corporation Tax, in line with the general principle under the Corporation Tax Act 2009 that excise duties incurred wholly and exclusively for the purposes of a trade are deductible, the two charges do not simply add together arithmetically. What they do is produce a combined effective burden on gross gaming yield that is substantially higher than either headline rate suggests in isolation, and that burden must be modelled correctly before any UK-facing remote gaming business can produce credible P&L projections.

This article builds that model step by step, explains the structural mechanics that determine the outcome, addresses group registration obligations under HMRC’s RGD regime, and positions the current regime against the pre-April 2026 economics that most operators’ legacy models still reflect.

What Does RGD Actually Tax?

RGD is charged on a licensee’s gaming provider profits from remote gaming played by UK-resident customers. Profits are calculated as stakes received from UK persons, less winnings paid out to UK persons. The tax applies on a place-of-consumption basis: it is irrelevant whether the operator is based in the UK, Malta, Gibraltar, or anywhere else. Any business providing remote gaming to a person who usually lives in the UK must register with HMRC, file quarterly returns via the Gambling Tax Service, and account for duty at 40% on the resulting figure.

That figure, stakes minus winnings, is, for most operators, broadly equivalent to gross gaming yield (GGY) for the relevant UK customer segment. It is not revenue in the accounting sense, and it is not net revenue after bonuses, although the treatment of free plays has specific rules under the RGD regime. Free plays offered by a gaming provider are included in the taxable profits calculation at their nominal stake value on first use. The HMRC policy paper published on 26 November 2025 confirmed that the government would not materially alter the existing taxable profits methodology when increasing the rate.

“The rate of Remote Gaming Duty will be increased from 21% to 40% from 1 April 2026 … the new duty rate will apply for accounting periods that begin on or after 1 April 2026 and will be chargeable on profits on remote gaming from that date onwards.”

The Deductibility Mechanism: How RGD Reduces the CIT Base

RGD is an excise duty. It is incurred in the course of carrying on a remote gaming trade and, absent any specific statutory exclusion, it qualifies as a deductible trading expense for Corporation Tax purposes under the general principles of the Corporation Tax Act 2009. HMRC has not published a specific statutory provision disapplying deductibility for gambling excise duties, and the treatment in practice, confirmed by the way major listed operators report their effective tax rates, reflects full deductibility.

The practical consequence is that RGD reduces taxable profit before CIT is computed. A business paying £4 million of RGD on £10 million of UK GGY does not then pay 25% CIT on £10 million, it pays 25% CIT on the remaining profit after RGD and all other deductible expenses. The statutory levy, introduced at 1.1% of GGY from April 2025 under the Gambling Act 2005 as amended, is similarly deductible for CIT purposes. The net effect is that every pound of RGD reduces the CIT charge by 25 pence, partially offsetting the headline duty cost, but only to the extent the operator is in a CIT-paying position.

Building the Combined Burden Model

The model below works with a stylised remote gaming operator generating £10 million of UK GGY, carrying operating costs (staff, technology, marketing, compliance, professional fees) of £3 million, and paying the statutory levy at 1.1% of GGY. This is a simplified illustration and operators should model their own cost structures with qualified tax advisers.

Line item	Pre-April 2026 (21% RGD)	Post-April 2026 (40% RGD)
UK GGY (taxable profits base)	£10,000,000	£10,000,000
Remote Gaming Duty	£2,100,000 (21%)	£4,000,000 (40%)
Statutory levy (1.1% of GGY)	N/A (pre-April 2025)	£110,000
Operating costs	£3,000,000	£3,000,000
Taxable profit before CIT	£4,900,000	£2,890,000
Corporation Tax at 25%	£1,225,000	£722,500
Total tax and levy charge	£3,325,000	£4,832,500
Effective rate on GGY	33.3%	48.3%
Post-tax profit	£3,675,000	£2,167,500

The CIT relief on RGD, 25% of £4 million, or £1 million, is real but modest relative to the gross duty increase of £1.9 million. The net cash cost of the RGD increase, after CIT relief, is approximately £1.425 million on this profile, not £1.9 million. That is the critical distinction for P&L modelling: the headline rate increase of 19 percentage points on GGY translates to a net cost increase of approximately 14.25 percentage points once CIT interaction is factored in, assuming the operator is fully profitable and CIT-paying at the main rate.

The effective combined rate on GGY of 48.3% in the post-April 2026 scenario rises to 53-55% for operators with thinner operating cost deductions, for example, leaner direct-to-consumer brands without significant UK-based workforce costs that generate additional CIT deductions. Conversely, operators with higher UK-deductible cost bases (substantial UK headcount, significant UK marketing spend, UK-based technology infrastructure) see a lower effective combined rate because the CIT base is further compressed.

What Changes if the Operator Is Loss-Making?

The deductibility argument only works for CIT-paying entities. An operator running at a taxable loss after RGD and operating costs accrues a deferred tax asset, not immediate relief. For groups operating through a single UK legal entity that is loss-making at the CIT level, common among newer entrants still investing in customer acquisition, the full 40% RGD charge falls on GGY with no concurrent CIT offset. The effective rate on GGY in that scenario equals 40% (RGD) plus 1.1% (statutory levy) on a cash basis, before any carried-forward loss relief crystallises.

This creates a meaningful asymmetry: profitable scale operators receive the CIT offset in the same accounting period as the RGD charge, while loss-making operators bear the full 41.1% cash burden on GGY and must wait for future profitability to receive relief. For operators forecasting a UK breakeven in years two or three of market entry, this timing difference has a material impact on cash flow modelling and funding requirements.

Group Registration: Structure and Risk

HMRC’s RGD regime permits corporate bodies under common control to form a group for duty purposes. The group must appoint a Group Lead Member (GLM) responsible for all transactions with HMRC, including returns and payments. All members of the group are jointly and severally liable for one another’s duty. The GLM must have a principal place of business in the UK, offshore-headquartered groups operating through a UK entity can satisfy this requirement through that entity, but the structural implication is that the UK entity’s solvency and HMRC relationship become critical for the entire group’s RGD compliance position.

HMRC may require a security deposit where an operator needs to appoint a UK representative (for businesses not based in the UK or in jurisdictions with tax enforcement agreements, which include Gibraltar, the Isle of Man, and the Crown Dependencies of Guernsey and Alderney). The security amount is set at six months of estimated duty liability, payable as a cash deposit, bank guarantee, performance bond, or joint account arrangement. At a 40% RGD rate, six months of estimated duty on a £10 million annualised GGY business equals approximately £2 million, a material liquidity consideration for mid-tier operators.

“A group can be formed by corporate bodies under common control and must appoint a Group Lead Member (GLM). The GLM is responsible for all transactions with HMRC and must have a principal place of business in the UK. All members of a group are jointly and severally liable for all other group members.”

For groups with multiple UK-licensed entities, for instance, a group holding separate remote casino and remote betting licences through different legal entities, the decision whether to combine those entities into a single RGD group, or maintain separate registrations, has both administrative and structural implications. A single group registration consolidates the returns and centralises the GLM liability. Separate registrations preserve entity-level ring-fencing of any duty default. Neither approach eliminates the underlying duty liability, but the risk allocation within the group differs materially.

CIT Group Relief: Does It Help?

UK Corporation Tax group relief, available under Part 5 of the Corporation Tax Act 2010, allows a company to surrender trading losses to another group company in the same period. For a gambling group where one UK entity generates taxable losses (for instance, a customer-acquisition-heavy sportsbook entity) and another is CIT-profitable (for instance, an established online casino entity), the loss surrender can reduce the profitable entity’s CIT charge, indirectly accelerating the relief on RGD paid by the loss-making entity.

The key constraint is that group relief operates only within the same accounting period for current-year losses (or within specific rules for carried-back claims). Cross-border group relief is generally unavailable following post-Brexit changes to the rules on European Economic Area surrendors. Groups structured with holding companies in Malta, Gibraltar, or the Isle of Man cannot route those offshore losses into UK group relief claims. The UKGC requires remote operating licensees to be fit and proper and to demonstrate adequate financial resources, but the licensing regime does not itself prescribe corporate structure for tax purposes, that determination rests entirely on HMRC guidance and CTA 2010 provisions.

In practice, operators should treat group relief planning and RGD group registration as two independent but interacting decisions. A UK RGD group does not automatically constitute a CIT group for group relief purposes, and vice versa. Compliance teams coordinating the two structures should ensure that each is formally constituted under the applicable HMRC requirements and documented in the group’s transfer pricing and governance records.

The Pre-2026 Benchmark: How Much Has Changed?

Using the same modelling approach, the pre-April 2026 combined effective rate on GGY for the same operator profile (£10m GGY, £3m operating costs, 21% RGD) was approximately 33.3%. The post-April 2026 combined effective rate on the same profile reaches 48.3% with the statutory levy included. That is a 15-percentage-point increase in the effective rate on GGY, not a simple 19-point increase (the headline RGD change) because the CIT interaction partially absorbs the increase.

Period	RGD Rate	Statutory Levy	Effective Rate on GGY (illustrative)	Net Post-tax Margin on GGY
Pre-April 2019	15%	Nil	~23%	~41%
April 2019, March 2025	21%	Nil	~30%	~37%
April 2025, March 2026	21%	1.1%	~31%	~36%
From April 2026	40%	1.1%	~48%	~22%

The table uses the same illustrative cost structure throughout. The step between the April 2025 position and the April 2026 position, a 17-percentage-point deterioration in effective rate, reflects the scale of the change. Post-tax margin on GGY roughly halves for an operator with this cost profile. For a pure-play online casino operator with lower operating costs relative to GGY, the compression is more severe still because the CIT deduction base is thinner.

Flutter Entertainment, reporting in November 2025 immediately after the Autumn Budget, estimated an adjusted EBITDA impact of approximately $320 million in 2026 and $540 million in 2027 before mitigation. Evoke, which owns William Hill, Ladbrokes, and Coral, projected £125 million to £135 million in additional annual duty costs, with approximately £80 million hitting financial year 2026. Both figures reflect gross RGD exposure before CIT offset, which is how operators typically communicate duty impact to investors, the CIT relief materialises in the deferred tax and current tax lines, not in the adjusted EBITDA figure that most market participants focus on. Compliance and finance teams modelling business cases for the board must be explicit about whether their RGD exposure figures are gross or net of CIT relief.

The Statutory Levy: A Third Layer in the Model

The statutory levy on gambling operators came into force on 6 April 2025 under Section 123 of the Gambling Act 2005 (as amended). It replaced the previous voluntary system of operator contributions to research, prevention, and treatment of gambling harm. The levy is assessed on GGY, with the rate varying by operator size, the headline rate for most licensed operators is 1.1% of GGY. It is collected by HMRC as part of the gambling duty regime and is deductible for CIT purposes on the same basis as RGD.

The levy’s interaction with the combined burden model is straightforward: it adds 1.1 percentage points to the GGY charge, partially offset by a CIT saving of 0.275 percentage points (25% of 1.1%), producing a net effective addition of approximately 0.825 percentage points to the combined effective rate. On a £10 million GGY business, that translates to approximately £82,500 of additional net annual cost. The levy is not trivial for smaller licensees, but it does not materially change the structure of the combined burden analysis, the RGD change is the dominant variable by a factor of roughly twenty.

How UK Gaming Tax Compares to European Peers

A PricewaterhouseCoopers study prepared for the Betting and Gaming Council in October 2025 compared the weighted average effective gambling tax rate across 17 European jurisdictions. At 21% RGD, the UK was broadly in line with the European average. At 40% RGD, the UK’s effective gambling tax rate, when measured as a proportion of GGY, moves materially above the European central tendency, though the comparison is complicated by the fact that most European jurisdictions apply their gambling tax at the operator level rather than distinguishing between gaming and betting as the UK post-2026 regime does.

Spain taxes online gambling at 20% of GGY under the DGOJ regime. Italy applies rates of 25% on online casino and 22% on sports betting. France taxes online sports betting and poker on stakes rather than GGY, producing effective GGY-equivalent rates that are lower for profitable operators. Germany’s interstate treaty regime applies 5.3% tax on stakes for online slots, which at typical hold rates translates to a GGY-equivalent rate substantially below 40%. The UK’s post-2026 RGD rate is, by any reasonable metric, among the highest statutory gambling excise rates in Western Europe for online casino-style products.

What Happens in April 2027?

The Autumn Budget 2025 introduced a further change that takes effect from 1 April 2027: a new remote betting rate within General Betting Duty at 25%, applying to all remote bets except those on UK horse racing (which remain at 15%) and bets placed via self-service betting terminals on licensed premises (also remaining at 15%). For operators running integrated sportsbook and casino products, the majority of major UK licensees, the April 2027 change compounds the April 2026 change.

An integrated operator’s UK GGY from betting was previously taxed at 15% GBD. From April 2027, it will be taxed at 25% GBD. The CIT interaction applies in the same way: GBD is also a deductible trading expense, so the net cost increase per pound of UK betting GGY is approximately 10% (the gross rate increase of 10 percentage points) multiplied by 0.75 (the CIT relief factor at the 25% main rate) = 7.5 percentage points net. HM Treasury projects the full package to raise over £1 billion per year in additional revenue by 2029 to 2030, with the OBR’s forecast underpinning that figure.

HM Treasury consulted during spring 2025 on a single Remote Betting and Gaming Duty (RBGD) that would harmonise RGD, GBD, and Pool Betting Duty into one levy with one registration and quarterly returns. The government’s November 2025 response to that consultation confirmed it would not proceed with RBGD, retaining separate duty streams. The consultation remains relevant to long-term planning because the government reserved the right to revisit harmonisation in future Budget cycles. Operators building five-year tax models for UK operations should include a scenario in which a harmonised rate is set at or above the current 40% RGD rate.

Practical Consequences for Compliance and Finance Teams

The combined burden model has several direct implications for how compliance and finance functions should structure their work.

Quarterly RGD accounting periods must now be reconciled against the CIT computation at the entity level. Where the RGD accounting period does not align with the CIT accounting period, common for operators with non-December year-ends, timing differences arise that affect deferred tax balances. The RGD return is due one calendar month after the end of each quarterly accounting period, the CIT payment schedule for large companies operates on a different instalment timetable. Finance teams must maintain a parallel tracking system that maps RGD quarterly liability to the appropriate CIT period deduction.

Record-keeping obligations under HMRC’s RGD regime require operators to retain records for four years, covering all UK-person stake and payout data used to compute taxable profits. This overlaps with UKGC data retention requirements under the Licence Conditions and Codes of Practice, which impose their own record-keeping obligations on licensees. Compliance teams should confirm that their data architecture satisfies both sets of requirements from a single data source rather than maintaining duplicate record sets that risk divergence.

Transfer pricing is a live issue for groups that route UK GGY through intercompany arrangements, for instance, where a UK-licensed entity pays a royalty or service fee to an offshore IP holding company. Such payments reduce the UK entity’s CIT base and may also reduce the UK entity’s RGD base in certain configurations. HMRC will scrutinise intercompany arrangements that have the effect of reducing UK taxable profits where the economic substance of the gaming activity is UK-facing. Operators should ensure that transfer pricing documentation for any UK gambling entity reflects arm’s-length pricing and is updated to reflect the post-April 2026 duty regime, as the economic analysis underpinning the pricing will have changed materially.

Finally, operators holding UKGC remote operating licences are required to demonstrate financial resources adequate to carry on their licensed activities. The LCCP imposes an ongoing fit-and-proper and financial adequacy standard. A business whose post-tax margin on UK GGY has compressed from 37% to 22%, the illustrative shift in the modelling above, may need to revisit its financial adequacy representations if that compression threatens its regulatory capital position. This is not a hypothetical concern: Playtech stated publicly in March 2026 that the RGD increase would make its Sun Bingo business unprofitable, and Evoke announced the closure of over 200 William Hill retail shops in part as a response to the duty change. Compliance officers at affected businesses should flag the tax impact to senior management in the context of their UKGC licence conditions, not only in the context of investor communications.

Operators should consult qualified UK tax counsel and regulatory legal advisers before making structural decisions, including group reorganisations, entity consolidations, or market exits, in response to the new duty regime. The interaction between RGD, CIT, group relief, transfer pricing, and UKGC licensing conditions is multidimensional, and the tax consequences of structural changes can be irreversible.
