One gambling app can contain a slot game and a football bet. On the tax return, they are not the same product. Britain increased Remote Gaming Duty from 21% to 40% on 1 April 2026, primarily affecting online casino gaming. The new 25% remote-betting rate within General Betting Duty starts on 1 April 2027. In September 2026, the first change is already in force; the second is enacted but not yet operative. Neither percentage is a levy on every pound a player stakes. Both concern defined operator profits. HMRC's gambling-duty changes · current duty-rate table
For a business that sells both casino games and sports bets to UK customers, that creates two clocks in the same cashier. The rate depends on the activity, the relevant accounting period and, for some bets, where and how the wager is made. A single headline about “the gambling tax” flattens those distinctions just when finance, trading and product teams need them most.
Casino changed first; remote betting waits another year
The 40% Remote Gaming Duty rate applies to a provider's remote-gaming profits from UK customers from 1 April 2026. HMRC's current notice says the earlier rate was 21%. The Finance Act 2026 also deals with an accounting period that straddles the change: profits are apportioned so the higher rate applies to the post-1-April portion, not retroactively to an entire earlier period. This is a rate on the operator's statutory duty base, not a 40% surcharge added to a customer's slot spin. HMRC Remote Gaming Duty notice · HMRC operative-date explanation
For ordinary remote sports bets, the higher General Betting Duty rate is still ahead. HMRC's 2026–27 rates table shows 15% on the relevant net stake receipts for fixed-odds bets, while the policy document sets 25% on profits from qualifying remote betting from 1 April 2027. The new rate sits *inside* General Betting Duty; it does not turn every wager into Remote Gaming Duty or create a single tax for all gambling on a phone.

The distinction also follows customers rather than the headquarters sign. HMRC says its remote gambling duties operate on a place-of-consumption basis: an operator serving UK customers can be liable even if it is based elsewhere. This tax boundary is related to, but not identical with, the licensing question in our guide to supplier and operator licences. A licence identifies permission for an activity; the duty calculation asks what taxable activity and customers the operator has. HMRC's tax scope
The 40% and 25% are not percentages of turnover
A bookmaker can accept £100 in stakes and pay out £90 in winnings. The customer has moved £100, but the simple difference is £10 before the operator's other costs. HMRC describes General Betting Duty for ordinary general bets through stake money due to the bookmaker less winnings actually paid out in the accounting period, with detailed timing and adjustment rules. Remote Gaming Duty has its own calculation, broadly gaming payments due from UK customers less qualifying prizes or amounts assigned to prize pools. Neither is a flat percentage of gross deposits, handle or the number displayed as total wagers on a dashboard. HMRC General Betting Duty notice · HMRC Remote Gaming Duty calculations
If a qualifying product line had £100 of correctly calculated dutiable profit, 40% would be £40 of Remote Gaming Duty on the gaming line. A qualifying remote-betting line with the same taxable-profit figure would produce £15 of General Betting Duty under the current general rate and £25 under the future remote rate. That is an illustration of rates, not a tax estimate for any operator: the two profit definitions, permitted adjustments, bet mix and accounting-period treatment still have to be worked through. Our GGR versus NGR explainer shows why an operator's commercial revenue labels cannot simply be swapped for a statutory tax base.
The tax rise is not a new price on the screen
A higher duty rate cannot be translated mechanically into a particular player's loss. A casino game may have a disclosed theoretical return, but that is a mathematical property of a game version, not an automatic tax pass-through. We explain the distinction in casino RTP explained. The rate change affects the operator's economics; any later change to odds, pricing or game configuration would be a separate business and product decision.
HMRC's impact note says individuals *could* be affected if a business passes the increase on through less favourable odds or game returns. That conditional wording matters. It does not document a universal change in sportsbook margins, a mandated slot setting or a measured movement of players to unlicensed sites. Those would require operator-level decisions and evidence after the tax change. HMRC assessment of possible consumer effects
The exceptions are part of the story, not footnotes
From April 2027, remote bets wholly on horse racing taking place in the UK remain outside the new 25% rate and are described by HMRC as staying at 15%. The government's stated reason is that operators already contribute to the statutory Horserace Betting Levy, which it characterises as an additional 10% contribution and an existing *de facto* combined burden of 25%. That comparison is the government's rationale, not a statement that the levy and duty are one identical charge calculated on every bet the same way. HMRC policy explanation · Finance Act 2026, section 87
The place of a terminal matters too. A self-service betting terminal on licensed betting premises is not treated as a remote bet for this new rate, even though a customer touches a screen; the general-betting rate remains 15% for that class. The change also leaves pool betting and spread-betting rates outside the new remote-betting band. A digital interface is therefore not enough to classify a wager. The legislation and HMRC's description look at the bet type and channel, not just whether electricity is involved. HMRC exceptions · Finance Act definition of a remote bet
There is a third April 2026 change that can be lost in a casino-versus-sportsbook headline: Bingo Duty was abolished. That was presented as support for bingo clubs and simplification, not as an exemption from all gambling taxes for anything called bingo. Operators selling more than one product still need to classify their activities under the relevant rules. HMRC policy note
Why the Treasury kept the two categories apart
The government originally consulted on a single Remote Betting and Gaming Duty. It did not adopt that model. In its response to 143 consultation submissions, it reported substantial opposition to merging casino gaming and betting into one rate. The stated distinction was that betting on real-world events has different cost and risk characteristics from online games of chance. That is the policy argument behind the two rates; it is not an independent finding that every casino product is more harmful than every bet or that every bookmaker has the same margin. Treasury consultation response
The government explicitly wanted the biggest rise on remote gaming, saying it viewed that category as generally lower-cost and associated with more harm. At the same time it recognised costs linked to betting and chose a smaller, later rise for remote wagers. Industry respondents had argued that a uniform rate might reward companies for pushing customers towards cheaper-to-operate casino products. The Treasury's answer was not to freeze betting duty forever: it separated the products and raised both rates on different dates. HMRC policy objective · consultation arguments and response
Its fiscal estimate is also easy to misread. HMRC's impact note projects an £810 million increase in receipts for 2026–27 and £1.065 billion for 2027–28 from the package. Those are government forecast effects across the measures, not money already collected, not revenue from one operator and not proof of how customer behaviour will change. The note says any consumer effect depends on whether businesses pass the increase through in odds or game returns. It leaves the response to the companies. HMRC impact assessment
The live question for a mixed casino-and-sportsbook operator is therefore not whether “UK online gambling” has one new tax rate. It is whether its books, product classifications and pricing decisions can keep pace with a casino rate already at 40%, a qualifying remote-betting rate moving to 25% in 2027, and activities that remain at different rates. A newspaper headline can merge the products; a tax return cannot.
