P60 & Salary Mismatch

I have a P60 from my employer that states that a certain amount of tax & NI contributions have been deducted from my gross pay for 2022-2023 leaving me with a certain net pay. Unfortunately, my employer appears to be in the process of going insolvent and some salary payments from that tax year have been reduced or missed. The final total for the salary that arrived in my bank account is significantly less than the amount suggested by the P60. I also assume that I will not see those missing salary payments at any point in the future. How should I declare this on my self-assessment tax return? At the moment, I have put in the details from the P60. I have also added a note in the section of my earnings due to the employer stating that I haven’t been paid the full amount. Is that correct, or should I do something else?

Hi

If the figures on your P60 do not match the payments you received, you will need to conrtact the employer to review.
If the P60 is incorrect the employer would need to submit the amended details to HMRC and yourself. If incorrect, once reviewed then you will need to amend the Self Assessment with the correct figures.
Please see If you need to change your return

Thank you
