30 December: Self Assessment Deadline!

1st December 2023

Don’t forget the 30 December Self Assessment Deadline!


If you want HMRC to automatically collect tax you owe from your wages and pension you need to submit your tax return online by 30 December and if so you are able to pay your Self Assessment bill through your PAYE tax code as long as all these apply:


  • you owe less than £3,000 on your tax bill (you cannot make a part payment to meet this threshold)
  • you already pay tax through PAYE, for example you’re an employee or you get a company pension
  • you submit your online tax return online by 30 December



When you cannot pay through your tax code
You will not be able to pay your tax bill through your PAYE tax code if:
  • you do not have enough PAYE income for HMRC to collect it
  • you’d pay more than 50% of your PAYE income in tax
  • you’d end up paying more than twice as much tax as you normally do
  • you owed £3,000 or more but made a part payment to reduce the amount you owe to less than £3,000


The tax you owe will be taken from your salary or pension in equal instalments over 12 months, along with your usual tax deductions.


If you’re self-employed you cannot pay Class 2 National Insurance through your tax code, unless it’s been due since before 6 April 2015. You must use one of the other ways to pay by the deadline instead.
