Local accountants and tax advisers, Trueman Brown, advise taxpayers that if they owe no more than £3,000 in tax for 2023/24, they may be able to pay their tax bill through PAYE if you file your tax return by 30 December 2024.

If you need to file a self-assessment tax return for 2023/24, you must do this online by 31 January 2025 if you want to avoid a late filing penalty.

However, if you received your notice to file a tax return after 31 October 2024, a later deadline applies; you must file the return within three months of the date of the notice to file.

You must also pay any remaining tax that you owe for 2023/24 by 31 January 2025.

If you are self-employed, this is also the deadline for paying Class 2 and Class 4 National Insurance for 2023/24.

Where your tax and Class 4 National Insurance liability for 2023/24 is at least £1,000, you must also make your first payment on account for 2024/25 by the same date, unless at least 80% of your tax liability for the year is collected at source, for example, under PAYE.

The need to pay any remaining tax and National Insurance for 2023/24 plus the first payment on account for 2024/25 by 31 January may present something of a financial challenge, particularly given the cost-of-living crisis.

However, if you have a source of income that is taxed under PAYE, there is a way to spread the cost without the need to agree to a Time to Pay arrangement — by opting to pay your self-assessment bill through PAYE.

Am I eligible?

You can pay your self-assessment tax bill for 2023/24 through PAYE if:

  • you owe less £3,000 on your tax bill.
  • you already pay tax through PAYE (for example, on employment or on a pension).
  • you submitted your 2023/24 tax return online by 30 December 2024 or you filed a paper tax return by 31 October 2024.

However, you will not be able to choose this route if:

  • your PAYE income is insufficient to collect the tax that you owe (in addition to the tax on that income).
  • as a result of the adjustment, you would pay more than 50% of your PAYE income in tax.
  • collecting self-assessment tax through PAYE would more than double the tax paid in this way; or
  • your tax bill was more than £3,000 but was reduced below this amount as a result of payments on account.

If you owe more than £3,000, you cannot use this option – it is not possible for £3,000 to be collected under PAYE and the balance to be paid by 31 January.

However, if you are struggling to pay, you could consider setting up a Time to Pay arrangement to spread the cost.

Where you elect to pay your 2023/24 self-assessment tax bill through PAYE, your 2024/25 tax code will be adjusted to collect the tax throughout the 2024/25 tax year.

This effectively allows you to spread the cost over 12 months and pay in interest-free instalments. In a climate of rising interest rates, this is an attractive option (although on the downside, it will reduce your take-home pay each month).
