Jot down a few questions to make the most of your conversation.
Can you file taxes online after the deadline?
Yes, in many cases you can still file your Self Assessment tax return online after the deadline in the UK. HMRC’s online service usually remains open after 31 January, so you can submit a late return even if you have missed the cut-off date.
However, filing late does not mean you avoid the consequences. HMRC can charge penalties and interest, so it is best to file as soon as possible once you realise you are behind.
What happens if you miss the deadline?
If you miss the online filing deadline, HMRC may issue an automatic late filing penalty. The first penalty is usually £100, even if you do not owe any tax. This can apply whether you are one day late or several months late.
Further penalties can build up if the return remains outstanding for longer. Interest may also be charged on any tax you owe, so the longer you wait, the more the total cost can increase.
Can you still pay online?
Yes, you can usually still pay your tax bill online after the deadline. HMRC offers several payment methods, including bank transfer, debit card, Direct Debit, and through your online account.
If you cannot pay the full amount straight away, it may still be worth filing the return on time, or as soon as possible, and then contacting HMRC. In some cases, you may be able to set up a Time to Pay arrangement to spread the cost.
How to file late online
To file late, log in to your HMRC Self Assessment account and complete the return as normal. The online system will still allow you to submit it, even if the deadline has passed.
Make sure all figures are accurate and that you include any income, expenses, and reliefs that apply to you. If you are missing information, use reasonable estimates where necessary and correct them later if needed.
What should you do next?
If you have missed the deadline, do not ignore it. File the return as soon as you can, check whether you owe tax, and arrange payment if needed.
It is also sensible to keep records of your submission and any communication with HMRC. If you think you have a reasonable excuse for filing late, you may be able to appeal a penalty, but this is not guaranteed.
