Minimum wage parameters have no 2023-24 rates, so 2023 uses the 2022-23 rates #2044
Description
policyengine_uk/parameters/gov/hmrc/minimum_wage/non_apprentice.yaml and apprentice.yaml jump from 2022-04-01 to 2024-04-01 in every band. The parameters have no 1 April 2023 entry. convert_to_fiscal_year_parameters (policyengine_uk/utils/parameters.py) reads each parameter at 30 April, so 2023 reads the April 2022 rates.
On main (15de0ca), minimum_wage for 2023 gives:
| Band | Model, 2023 | Law from 1 April 2023 (S.I. 2023/354) |
|---|---|---|
| 23 and over (national living wage) | 9.50 | 10.42 |
| 21 to 22 | 9.18 | 10.18 |
| 18 to 20 | 6.83 | 7.49 |
| Under 18 | 4.81 | 5.28 |
| Apprentice | 4.81 | 5.28 |
Source: The National Minimum Wage (Amendment) Regulations 2023, reg. 2(2) and 2(3), in force 1 April 2023.
Every other year from 2015 to 2026 matches the statutory instruments. The age thresholds (0, 18, 21, 23, 25) are constant. That is correct as long as a band shares the rate of the band above it while the law groups them: the national living wage applied from 25 (April 2016), from 23 (April 2021, S.I. 2021/329) and from 21 (April 2024, S.I. 2024/432).
minimum_wage feeds uc_minimum_income_floor, tax_free_childcare_meets_income_requirements and extended_childcare_entitlement_meets_income_requirements, so their 2023 values use the 2022 rates too.
Found while adding ESA exempt-work tests (#2031). #1999 (draft) also adds the 2023 rates as part of a larger change.
