Daily penalties for late self-assessment returns
If you miss the deadline for submitting a self-assessment tax return or for paying outstanding tax, HMRC can charge ongoing interest and financial penalties.
About 1.1 million people failed to submit their 2022–2023 self-assessment returns on time before the deadline of 31st January 2024, and now face daily penalty charges.
From 1st May, HMRC has been applying a £10 daily penalty for late submissions. This can run for up to 90 days, potentially reaching the maximum late fine of £900.
This penalty applies for late tax return submissions even if no tax is owed. For those with outstanding tax payments, HMRC can also charge up to 7.75% late payment interest, on top of a penalty of up to 5% of the outstanding balance.
The longer it takes to file your self-assessment tax return and pay any tax you owe, the more you’ll end up paying – so what should you do if you receive a penalty notice?
