Self Assessment taxpayers who do not make their 2021-22 balancing payment by 3 March 2023, face a 5% late payment penalty. A penalty may be avoided by setting up a Time to Pay agreement before the penalty deadline.

  • The balance of any tax due for 2021-22 is payable by 31 January 2023. Late payment penalties do not apply if the payment is made within 30 days of the normal due date
  • If you make your tax payment or set up a Monthly payment plan set up by midnight 3 March 2023 no 5% late payment penalty will be charged.  
    • Interest will be charged from 1 February 2021.  
  • Late filing penalty also applies if you failed to file your tax return by 31 January 2023.
  • For help and support about paying tax liabilities, HMRC can be contacted on 0300 200 3822.
