HMRC Self Assessment Penalties | How to Avoid Them?

Table of Contents

Filing your Self Assessment tax return can be overwhelming and can make the tax year stressful. You have to gather receipts, log expenses, and calculate your earnings. During all this, you may miss the self-assessment deadlines. But this is not good; missing these deadlines is a costly mistake as it results in HMRC Self Assessment penalties.

In the UK, HM Revenue and Customs (HMRC) enforces strict financial penalties for late submissions and overdue payments. So, it is important to stay ahead of these deadlines to avoid these fines.

Let’s understand how these penalties work and how the system is changing so you can save hundreds of pounds.

What are HMRC Self Assessment Deadlines?

Before getting started with HMRC Self Assessment penalties, you must know the self-assessment deadlines. The UK tax return period runs from 6 April to 5 April the following year. You must meet the key deadlines of self-assessment to avoid penalties.

The deadline for paper tax returns is 31 October. Additionally, the deadline for online tax returns and paying your tax bill is 31 January. Missing these deadlines will automatically trigger HMRC penalties.

What is a Self-Assessment Late Payment Penalty in the UK?

An HMRC Self Assessment late payment penalty is a financial fine that the UK government charges if a taxpayer misses their tax bill on time. People often confuse the late filing penalty with the late payment penalty.

Remember, the HMRC late filing penalty punishes you for missing the paperwork deadline. On the other hand, late payment penalties punish you for missing the 31 January deadline to transfer the tax bill you owe.

What are HMRC Self Assessment Penalties?

Basically, HMRC Self Assessment penalties are fines that the UK government charges when you do not meet your tax obligations on time. You may receive a penalty if:

  • You submit your Self Assessment tax return late
  • Pay your tax bill after the deadline
  • Provide incorrect information

The amount of the penalty you pay depends on the type of penalty and how long the issue remains unresolved.

What are the Late Filing Penalties?

The late filing penalty is one of the HMRC Self Assessment penalties. When you file your tax return late, it results in an automatic fine. These fines apply even if you have no tax to pay, or if you have already paid the tax you owe. This means that if HMRC requires you to submit a Self Assessment tax return, you must file it by the deadline.

Here are the details of late filing penalties:

  • As soon as the deadline passes, you get an immediate £100 fixed penalty. This penalty applies even if you do not have to pay a tax bill.
  • If you are 3 months late, you get daily fines of £10 per day for 90 days. This adds up to an extra £900.
  • If you are 6 months late, an additional fine of £300 or 5% of the tax due (whichever is greater) is charged.
  • If you are 12 months late, another £300 or 5% of the tax due (whichever is greater) is charged.

Note: your late payment penalty depends on when your tax was due and which HMRC’s penalty rules apply for that tax year.

What are the Late Payment Penalties?

When it comes to HMRC Self Assessment penalties, the late payment penalty is charged if your tax bills are unpaid. Filing tax returns on time is only half the battle. If you clear your filing work but miss the payment deadline, HMRC applies a separate set of percentage-based penalties.

Here are the details of late payment penalties:

  • If you are 30 days late, a penalty equal to 5% of the unpaid tax is charged.
  • If you are 6 months late for paying your tax bills, a further 5% penalty will be imposed on the remaining unpaid balance.
  • And, if you are a year late, a final 5% penalty is imposed on the outstanding amount.

What is the Daily Interest on the Amount?

In addition to the fixed percentage penalties, there is a hidden cost: daily interest. HMRC charges daily interest on all outstanding tax, and it is collected from 1 February until the day you pay the bill in full.

Why Does HMRC Issue Late Payment Penalties?

HMRC introduces a late filing penalty to encourage taxpayers to pay their tax bills on time. Missing a deadline leads to penalties, but HMRC may cancel them if you have a valid excuse. You may have to inform HMRC as soon as possible to cancel your HMRC Self Assessment penalties.

Common reasons you receive a late payment penalty include:

  • Failing to pay by the due date
  • Not setting aside enough money to pay taxes
  • Misunderstanding Self Assessment payment obligations
  • Unexpected financial problems
  • Assuming accountants will handle taxes

Note: You can receive a late payment penalty even if you submitted your tax return on time but did not pay the tax due by the deadline.

Can HMRC Cancel Self Assessment Penalties?

Yes, HMRC can cancel Self Assessment penalties if you have a valid excuse or if HMRC made an administrative mistake.

What Counts As a Reasonable Excuse?

Luckily, you can remove HMRC Self Assessment penalties if your situation qualifies as a reasonable excuse.

For HMRC, a reasonable excuse is an unusual or unexpected event that was outside your control and prevented you from paying your tax bills on time. HMRC views these excuses carefully.

Your excuse must have existed at the exact time the payment was due. Also, you must have paid the tax bill as soon as possible after the excuse ended.

What HMRC accepts to remove HMRC Self Assessment penalties:

  • An unexpected life-threatening medical emergency or hospital stay that prevented you from managing expenses.
  • Death of a close family member or partner.
  • A serious illness or unexpected medical emergency prevented you from dealing with your tax affairs.
  • System failures at the time of payment. You must have proof of the error message.

What HMRC does not accept:

  • Not having enough money is not accepted
  • Forgetting the deadline
  • Difficulty using HMRC’s online services
  • Relying on accountants to make payments automatically

How to Appeal HMRC Self Assessment Penalties?

If you think the penalty is wrong, or have a reasonable excuse, you will have to explain it to HMRC. You must submit your appeal within 30 days of your penalty notice to appeal an HMRC Self-Assessment late payment penalty. You can appeal the penalty online,  by letter, through your HMRC account, or by tribunal appeal if rejected.

Appeal Online

If you have a Government Gateway user ID, you can appeal against a Self Assessment penalty directly through your tax portal. Log in to your HMRC personal tax account and appeal a tax penalty.

By Letter

You can send a signed letter to the HMRC office if you don’t have an appeal form. In the letter, you need to explain why your payment was late. Moreover, you must include your name and reference number, such as UTR.

What Happens After Appealing for A Penalty?

Once you send your appeal against HMRC Self Assessment penalties, you will get a penalty decision letter from HMRC that will offer you a review. Moreover, if you have already paid the fine, HMRC will refund it to your bank account.

Tribunal Appeal

If HMRC rejects your appeal, you can appeal further to an independent First-tier Tribunal. Within 30 days, you will have to accept the offer of a review or appeal to the tax tribunal.

How to Avoid HMRC Self Assessment Penalties?

You can avoid self-assessment penalties, and the most effective way is to ensure you pay your tax to HMRC by midnight on 31 January. If you cannot afford to pay, you should take action before the deadline to protect yourself from HMRC penalties.

Here are the effective steps to take to avoid the late Self Assessment Penalty:

  • Stay ahead of the self-assessment deadlines
  • If you cannot afford your tax bill, contact HMRC. HMRC can help you prevent late payment penalties by setting up a Time to Pay arrangement (TTP).
  • You can use HMRC’s Budget Payment Plan if you struggle with cash flow at the end of January.
  • Another way to prevent HMRC Self Assessment penalties is to file your tax returns early. Don’t wait until January to file your paperwork.
  • If your tax bill is more than £1,000, HMRC may require you to make payments on account. These are the advance payments towards your next year’s tax due on 31 January and 31 July.
  • Track income and expenses regularly and keep accurate records to avoid last-minute hassle.

What Happens If You File Your Tax Return But Cannot Pay?

If you file your tax return on time but cannot pay the bill, you avoid the expensive late-filing penalty. However, you will face late-payment interest and potential penalties on the unpaid amount. Filing your return on time is important even if you cannot pay immediately.
