Correcting Wrong Tax Code

MG1960

I would appreciate advice on how I might get my  tax code corrected. I applied the marriage allowance and then cancelled it some 2 weeks later. The inland revenue are now suggesting that I owe £1500 in underpaid tax and adjusted my code to collect! I have spoken to them via the phone twice ( 50 minute wait). Apparently they are unable to correct this until they receive my end of year p60 information. So any suggestions or advice on how I can get this corrected or how I can contact them would be useful.. Thanks Marcus

What has happened to the MA refund money ?  If that is still being processed then you do likely owe tax, if not then it will be corrected back in due course.

So I contacted the revenue again today and the caller handler believes that the cancellation of the marriage allowance has taken place? However apparently I still owe under paid tax by £300 which I didn't before the 25th March when I initially applied for the allowance. The caller handler wasn't able to give any explanation. Does anyone know how you get an explanation?

If you provide sufficient information it should be possible to work out what has happened.

Which tax years have you received P800 calculations for?

What was the cumulative amount owed on the the final calculation?

Did you get a new tax code for 2020:21 and if so what did this show the tax underpaid for 2020:21 to be?

What is the amount of tax underpayment* included in your 2021:22 tax code?
*not the underpayment deduction in your code, the amount of tax the deduction is to collect

Has your spouse received any calculations showing receipt of the Marriage Allowance tax credit?
