So, Can I Submit a Late Tax Return Without a Fine?
Tax deadlines can be stressful, especially if you are juggling business responsibilities or personal commitments. Missing the submission date is a common worry for both sole traders and individuals with additional income. Many people ask the same question: Can I submit a late tax return without a fine?
The answer depends on how late you are, your circumstances, and whether HMRC accepts your reason for the delay. This guide explains what happens if you file late, when penalties apply, and how you can avoid unnecessary fines.
HMRC Deadlines You Need to Know
HMRC sets strict deadlines for Self Assessment tax returns:
- 31 October – deadline for paper returns
- 31 January – deadline for online returns and tax payment
If you miss either date, HMRC automatically issues a penalty. However, there are situations where you may not need to pay a fine, which we will explain below. More detail is available in the HMRC manuals.
What Happens If You File Late?
If you miss the deadline, HMRC usually applies the following charges:
- £100 fixed penalty – if your return is up to three months late
- Daily penalties – £10 per day after three months, up to 90 days (£900 maximum)
- Further fines – £300 or 5% of the tax due if more than six months late
- Additional penalties – another £300 or 5% of tax due if over 12 months late
These fines apply whether or not you owe tax.
Can You Avoid a Fine?
The key to answering “Can I submit a late tax return without a fine?” lies in HMRC’s concept of reasonable excuse. HMRC may cancel or reduce penalties if you can show you had a genuine reason for missing the deadline.
Examples of acceptable reasons include:
- Serious illness or hospitalisation around the deadline
- Unexpected bereavement of a close relative
- Issues with HMRC’s online service preventing submission
- Fire, flood, or other unexpected events affecting records
You must file your return as soon as possible after the issue is resolved. Evidence, such as hospital notes or correspondence with HMRC, is usually required.
Reasons that HMRC generally does not accept include:
- Forgetting the deadline
- Not having the money to pay your bill
- Relying on someone else to file on your behalf
Full guidance is available through HMRC income tax resources.
Interest and Late Payment Charges
Even if HMRC cancels your filing penalty, interest still applies if you pay your tax late. Interest starts accruing from 1 February. In addition, if your payment is more than 30 days late, HMRC can add further penalties of 5% of the unpaid tax.
This means it is always better to file and pay as soon as possible, even if you have missed the official deadline.
Avoiding Penalties in the Future
Filing late once can be stressful, but building better habits ensures you avoid repeating the mistake. Steps you can take include:
- Using digital systems to keep records organised
- Filing early rather than waiting until January
- Setting calendar reminders for deadlines
- Working with professional accounting services for ongoing support
For many individuals and sole traders, professional help not only reduces the risk of fines but also ensures all allowable expenses are included, lowering the final tax bill.
