The consequences of missing the self assessment deadline
When you miss the self-assessment deadline, HMRC doesn’t waste time in issuing penalties. Here’s a breakdown of what you can expect if you miss the deadline:
1. Immediate £100 penalty
As soon as the clock strikes midnight on 31st January, HMRC will automatically issue a £100 penalty for late submission. This penalty applies even if you don’t owe any tax or are due a refund.
2. Daily penalties
If your tax return is more than three months late, you’ll be charged an additional £10 per day for up to 90 days, which can total up to £900. This is on top of the initial £100 penalty.
3. Six-month penalty
If you still haven’t filed your return after six months, HMRC will impose further penalties. This could be either £300 or 5% of the tax due, whichever is higher. This penalty is in addition to the daily penalties.
4. Twelve-Month Penalty
If your tax return is more than 12 months late, HMRC may impose yet another penalty of £300 or 5% of the tax due, depending on the circumstances. In severe cases where HMRC believes you are deliberately withholding information, the penalty can increase to 100% of the tax due.
5. Late Payment Penalties
In addition to late filing penalties, if you fail to pay the tax you owe by the 31st January deadline, you’ll incur further penalties. These include:
5% of the unpaid tax if it’s 30 days late.
An additional 5% if it’s six months late.
Another 5% if it’s 12 months late.
6. Interest on late payments
HMRC will also charge interest on any unpaid tax from the day after the payment is due. The interest rate is set by HMRC and can change, so it’s important to settle your bill as soon as possible.
How to minimise the impact of missing the deadline
If you’ve missed the self-assessment deadline, there are steps you can take to minimise the penalties and get back on track:
1. File your return as soon as possible
The sooner you file your tax return, the better. Each day you delay can increase the penalties you face, so make it a priority to submit your return immediately.
2. Pay any tax owed
If you owe tax, pay it as soon as possible to avoid further penalties and interest. Even if you can’t afford to pay the full amount, paying what you can and contacting HMRC to arrange a payment plan can help reduce additional charges.
3. Appeal the penalty
If you have a reasonable excuse for missing the deadline—such as a serious illness, bereavement, or technical issues—you may be able to appeal the penalty. HMRC considers appeals on a case-by-case basis, so be prepared to provide evidence to support your claim.
4. Seek professional help
If you’re unsure how to proceed or need help navigating the appeals process, it’s wise to seek professional advice. This can help you avoid further penalties and ensure you’re on the right track going forward.
How to avoid missing the deadline in the future
Missing the self-assessment deadline can be stressful and expensive, but it’s avoidable with the right planning and tools. Here’s how you can ensure you don’t miss the deadline again:
1. Register for self assessment early
If you’re new to self-assessment, make sure you register with HMRC well in advance of the deadline. The registration process can take up to 10 working days, so don’t leave it until the last minute.
2. Keep accurate records
Throughout the year, keep detailed records of your income and expenses. This will make it easier to complete your tax return and reduce the risk of errors that could lead to delays.
3. Set reminders
Use calendar reminders or apps to notify you of important dates, such as the self-assessment deadline and payment deadlines. Setting multiple reminders leading up to the deadline can help keep you on track.
