Question to the HM Treasury:
To ask Mr Chancellor of the Exchequer, what assessment he has made of the cost to the public purse of raising the income tax allowance to £12,500.
The cost of raising the income tax Personal Allowance may be approximated using the “Direct effects of illustrative tax changes” table as published at the following address:
https://www.gov.uk/government/statistics/direct-effects-of-illustrative-tax-changes
The table shows the cost of a £100 increase and a 10% increase in the Personal Allowance in 2018-19 through to 2020-21. This can be used to scale the proportionate cost to raise the Personal Allowance to £12,500.
