What happens if you are late with self assessment tax return?
If your payment is made after the due date, or if you settle your tax bill late, please be aware that additional charges will apply. Late payments incur interest charges. For Self Assessment tax returns that are overdue by more than 3 months, and for any late payments, you can use our online tool to estimate your penalty.
In certain circumstances, if you have a valid and reasonable excuse for the delay, you have the option to appeal against the penalty.
How much does HMRC charge for late tax return?
Within 3 months after the filing date: £100 penalty.
More than 3 months after the filing date: £200 penalty, which supersedes the initial £100 charge.
Will HMRC waive late filing penalty?
If HM Revenue and Customs (HMRC) or the Tribunal acknowledges that you have a “reasonable excuse” for your late filing, the entire penalty will be waived. It is important to note that the ‘reasonable excuse’ must be applicable for the entire duration from the missed filing deadline up to just before the actual submission of the return.
