Penalties for late filing of tax returns

HMRC reports over 63,000 taxpayers filed their returns over the New Year, but 5.4 million still need to act before the looming 31 January 2025 deadline. File now to avoid penalties, pay your 2023-24 tax, and set up payment plans if needed to stay compliant.

The deadline for submitting your 2023-24 self-assessment tax return online is fast approaching—31 January 2025. This date is not just for filing your return; you also need to pay any tax due by this time. This includes settling any remaining tax from the 2023-24 tax year, plus the first payment on account for the 2024-25 tax year. It’s crucial to remember this deadline to avoid penalties.

If you miss the deadline, be aware of the penalties that can arise. The first penalty is an automatic £100 charge, which you will incur even if you do not owe any tax or if you have paid on time. If your return is still late after 3 months, you will face daily penalties of £10 per day, which can add up to a maximum of £900. After 6 months, another penalty kicks in, which is either 5% of the tax you owe or £300, whichever is greater. Then, if you are still late after 12 months, you will face another penalty of 5% of the tax due or £300, whichever is greater.

On top of these filing penalties, there are also penalties for late payment. If you do not pay your tax bill on time, HMRC charges 5% of the unpaid tax at 30 days, 6 months, and again at 12 months. Interest will also be charged on any outstanding amount.

If you are struggling to pay your tax, there is an option to set up a payment plan online, where you can spread the cost of what’s due by 31 January 2025 over up to 12 months. This option is available for debts up to £30,000, but you will need to set up the plan no later than 60 days after the due date. It is a good idea to set it up sooner rather than later because if your tax is still outstanding on 1 April 2025 and you have not made arrangements, you will face an additional 5% late payment penalty.

If you owe more than £30,000 or need longer than 12 months to pay, you can still apply for a time to pay arrangement, but you will not be able to do this through the online service. Make sure to file your return and pay on time to avoid these costly penalties.
