Question to the HM Treasury:

To ask His Majesty's Government how many UK adults are not liable to pay income tax because their total income is less than the tax-free personal allowance.

Data on the number of UK adults who are not liable to pay income tax are not currently held or published.

HMRC publishes projections for the total number of Income taxpayers per year in table 2.1 of the Income Tax liability statistics. Current projections show there to be 37.4 million Income taxpayers in the UK in 2024-25.

The Office for National Statistics publishes projections for the total number of adults in the UK by age in their population projections. They currently estimate there to be 55.2 million individuals aged over 18 in the UK in 2024-25.
