Offer private healthcare tax relief: calculation note
Assumptions behind the Offer private healthcare tax relief scenario. Implementation detail is incomplete, so uncertainty is explicit.
Central fiscal result
+GBP 3.5bn - Net fiscal impact in 2027-28
Low case: +GBP 1.0bn. High case: +GBP 8.0bn. Positive numbers are fiscal costs or borrowing pressure. Negative numbers are Exchequer savings or receipts.
Scenario and baseline
- Eligible private healthcare and insurance receives 20% tax relief.
- Relief applies to households and possibly employer schemes.
- No automatic NHS budget saving is assumed.
- Supply constraints are included in the uncertainty range.
Affected population
- Affected units are insured households, employers, insurers and providers.
- ABI reports rising private health claims and workplace cover.
- Higher-income households are more likely to benefit.
- NHS patients are affected only if capacity shifts.
Gross impact
- Central cost assumes GBP 17.5bn eligible spend times 20%.
- Low case assumes narrow eligibility and some NHS offset.
- High case assumes employer schemes and price growth.
- Deadweight spending is included in the central cost.
Fiscal build-up, central case
- Tax relief on private spending: +GBP 3.8bn
- NHS substitution savings: -GBP 0.4bn
- Administration: +GBP 0.1bn
- Administration and uncertainty: +GBP 0.0bn
Central net impact: +GBP 3.5bn in 2027-28.
Behaviour and pass-through
- Low case assumes relief induces some genuine NHS substitution.
- Central case assumes substantial deadweight subsidy.
- High case assumes premiums rise and employer schemes qualify widely.
- Private-sector staff demand may worsen NHS labour constraints.
Phasing
- 2026-27: +GBP 0.8bn. Preparation or partial implementation.
- 2027-28: +GBP 3.5bn. Main scenario year.
- 2028-29: +GBP 4.0bn. Behaviour and pass-through develop.
- 2029-30: +GBP 4.5bn. Steady-state uncertainty persists.
