Recovery of tax free allowance

Hello, in the last financial year I mistakingly crossed the 100k threshold and this year my tax code has changed to reflect my reduced tax free allowance. Is there any means of retrospectively making a 1 off payment into my pension to recover the full tax free allowance and tax code?

Hi,
The tax code may have reduced allowances if we have your estimated income as over £100,000, the PA is reduced by 1 for every £2 earned over £100,000.
Check your PTA to ensure we have the correct estimated income for yourself for this tax year.
If it has been reduced due to an underpayment of tax from the previous year, you could make a voluntary payment for this.
Thank you.
