The Tax Policy Changes document, which was published as part of Budget 2024, set out both the first and full year cost of tax policy measures. Carryover is calculated as the difference between the impact of a measure on a full year and on 2024.
The impact of carryover will be reviewed as part of the normal budgetary process, as there are several moving parts to be considered, such as the take-up of measures and specific tax-relevant factors, which could impact on the expected yield or cost of a given measure.
The budgetary stance for Budget 2025 will be set out in the Summer Economic Statement, which will be published in the coming period.
The net carryover impact into next year of expenditure measures will be considered as part of the estimates process.
