Hi Christopher Warenius,
Your Personal Allowance is £12570 in 2022 to 2023 tax year.
If you are a higher rate taxpayer, who pays into a pension scheme and is seeking to claim higher rate relief, your Personal Allowance does not change.
Instead, the basic rate band which is naturally between £12570 and £50270, changes.
You deduct the Personal Allowance from all of your taxable income, to find the amount that you will pay tax on.
Any amount above £50270 will be taxed at 40%.
If you are claiming higher rate pension relief for a pension payment of 3062, you add this figure to the basic rate band £50270 to become £53332 in this example, thus increasing the income taxable at 20% by 3062 and reducing the income taxable at 40% by 3062.

Thank you.
