Remove basic tax for NHS staff: calculation note
Assumptions behind the Remove basic tax for NHS staff scenario. Implementation detail is incomplete, so uncertainty is explicit.
Central fiscal result
+GBP 8.0bn - Net fiscal impact in 2027-28
Low case: +GBP 4.0bn. High case: +GBP 14.0bn. Positive numbers are fiscal costs or borrowing pressure. Negative numbers are Exchequer savings or receipts.
Scenario and baseline

- The relief lasts three years.
- Higher-rate tax above the basic band remains.
- Eligibility is narrower than all health and care employment.
Affected population
- Affected units are employee taxpayers in NHS and social care.
- NHS England HCHS headcount is about 1.54m.
- Adult social care has about 1.60m filled posts in England.
- Low-paid workers below tax thresholds gain less.
Gross impact
- Central case assumes about 2m eligible taxpayers after exclusions.
- Average tax relief is around GBP 4,000 per eligible worker.

Fiscal build-up, central case
- Income tax receipts lost: +GBP 8.2bn

- Administration and payroll changes: +GBP 0.1bn

- High case includes agency staff, devolved spillovers and classification pressure.
- Tax relief does not train new workers quickly.
