Late filing penalty
A late filing penalty is a fee charged by HMRC if you file your tax return late.
What is very important for you to know:
- there is a separate fine for paying your tax bill late, and they get added up. You also need to pay interest when you pay late
- you get fined for filing late even if you owe no money in taxes – but had to file for another reason, for example, if you were already registered for Self Assessment.
The late filing penalty starts at £100 if you’re a day late and it can increase all the way to £1,600 for a whole year. Use this late tax penalty calculator to get an estimate of how much you might have to pay.
You can appeal a fine with HMRC but you better have a good reason: things like fire, flood, bereavement, and illness.
