Change of employment status

I was self-employed in 2022/23 and changed to employee from April 2023. 1. Do I still need to pay First Payment on Account for 2023/24? 2. If I have to, will I be repaid by HMRC? How do HMRC repay me? Do I need to apply for repayment? 3. Do I need to complete my self assessment tax return for 2023/24 even my salary is the only source of income?

Hi Firsttime Payer,
If your self employment ceased 2022/23 and you no longer meet the Self Assessment criteria for 2023/24 we can close your record which will cancel the payments on account.
You can check if you meet the criteria at Check if you need to send a Self Assessment tax return and if no longer meet the criteria can send a referral to close your record and cancel the payments on account. 
Thank you.
