Treasury Officials Model Revenue Options from Slot Machine Duty Adjustments

Chancellor John Healey is reviewing proposals that would raise taxes on slot machines located in adult gaming centres and casinos, and these measures form part of a broader plan to generate several billion pounds for the October budget. Treasury officials have begun modelling the potential income that could come from increases to machine games duty on Category B £2-a-spin slots along with comparable equipment, while the work builds on previous adjustments applied to online gambling operators. The current exercise takes place as September 2026 ends and departments prepare detailed figures ahead of the autumn fiscal statement. Officials focus on Category B machines because these terminals operate under a fixed stake limit and generate measurable duty payments across thousands of venues. Data from recent quarters shows steady participation levels in land-based premises, which provides a baseline for revenue projections without requiring changes to player behaviour assumptions.

Scope of the Modelling Exercise

Work at the Treasury centres on machine games duty rates that apply to both standalone slots and linked terminals found in casinos. Category B machines accept a maximum £2 stake per spin, and any duty adjustment would affect the percentage of gross gaming revenue collected by the government. Analysts compile figures from operator returns and venue performance reports to estimate how different rate scenarios might translate into additional receipts over a full financial year.

Adult gaming centres represent one key segment under review because these locations house large numbers of Category B units alongside other gaming equipment. Casinos contribute through a smaller but higher-value machine estate that also falls under the same duty framework. The modelling accounts for variations in machine utilisation rates across urban and regional sites, which helps refine the projected yield from any rate change.

Connection to Earlier Online Gambling Adjustments

This land-based review follows tax increases already applied to online gambling platforms. Those earlier changes targeted remote betting and gaming operators, and the revenue they produced contributed to overall fiscal targets. Officials now examine whether similar duty uplifts on physical machines could deliver comparable results while maintaining consistency across different gambling formats.

Coordination between online and land-based policy strands allows the Treasury to assess total sector contributions rather than isolated segments. Figures released in prior budget documents indicated that combined gambling duties already form a notable revenue stream, and the current modelling seeks to identify incremental gains available from machine games duty without overlapping existing online measures.

Budget Context and Revenue Targets

The October budget faces pressure to close funding gaps across multiple departments, and gambling duty represents one area under active consideration. Treasury teams compare historical collection data with forward projections that incorporate modest rate increases on Category B terminals. These calculations include sensitivity analysis for possible shifts in machine numbers or average revenue per terminal following any duty change.

Category B £2-a-spin slots remain a stable component of the duty base because regulatory stake caps limit volatility in player spend. Officials therefore treat revenue estimates from these machines as relatively predictable when constructing budget scenarios. The inclusion of adult gaming centres and casinos broadens the modelling sample and captures differences in operating costs and machine density between venue types.

Process and Timeline Considerations

Work on the duty modelling began several weeks before the end of September 2026 and continues alongside other revenue-raising options under review. Teams cross-reference operator-submitted returns with venue licensing records to establish a clear picture of the existing machine estate. This data set supports multiple rate scenarios that officials present to ministers for final decisions ahead of the budget announcement.

Any duty adjustment would require legislative steps after the budget, and implementation timing would depend on the scale of the change and the need for system updates by operators. Past duty modifications have taken effect at the start of the following tax year, providing a precedent that shapes current planning assumptions.

Conclusion

The Treasury continues to refine its estimates for machine games duty increases on Category B slots and related equipment in adult gaming centres and casinos. These projections feed into preparations for the October budget and sit alongside earlier adjustments applied to online gambling. Officials maintain focus on verifiable revenue data from existing machine operations as they complete the modelling work.
