Question to the HM Treasury:

To ask Her Majesty's Government what projections they have made for expenditure on the Marriage Allowance in 2019–20, following changes to the basic and higher rates of personal tax allowance.

The estimated cost of Marriage Allowance is shown annually in the HMRC publication ‘Estimated costs of principal tax reliefs’ up to the current tax year and will be available for 2018-19 in the next publication (in early 2019). An estimate of future years cost is not provided as there is still uncertainty around the increase in take-up by the end of 2019-20.
