Self Assessment filing and tax payment deadline

Self Assessment filing and tax payment deadline

Update 29.1.21

On 25 January HMRC announced that Self Assessment customers will not receive a late filing penalty for their late tax return if they file online by 28‌‌ ‌February.

This easement is for late filing penalties only. It does not affect any other tax obligations. A return received in February will be treated in the same way as a return filed in February in a ‘normal’ year where there is a reasonable excuse – the penalty will not be charged but the return is treated as late for the purposes of enquiry windows, etc.

Tax still needs to be paid by 31‌‌ ‌January. Interest will be charged from 1‌‌ ‌February on any outstanding liabilities. If any tax remains outstanding on 3‌‌ ‌March, customers will be charged a late payment penalty of 5% of the amount still due.

Customers that do not pay in full by 31‌‌ ‌January will be able to use a Self Serve Time to Pay service on GOV.UK to set up an affordable plan where they can pay over time in instalments. Interest will still be charged but if they set up the payment plan before 3‌‌ ‌March, they won’t be charged a late payment penalty as long as they keep to the terms of the payment plan.

The easement for late filing penalties will be applied to SA700s and SA970s filed in February. These returns can only be filed on paper.

For SA800 and SA900 we will apply the easement if customers file online by the end of February. Their paper deadline was 31‌‌ ‌October so if customers file on paper in February they will not get the easement.

Those customers affected by HMRC Exclusions, who had until 31‌‌ ‌January to file on paper, will avoid a late filing penalty provided they file their return by 28‌‌ ‌February.
