Thousands of UK households could face automatic £100 fines from HMRC if they fail to meet the fast-approaching deadline for paper self-assessment tax returns. The cut-off, set for midnight on October 31, is fixed and applies even if the form arrives just a single day late.
While many taxpayers now file online, a significant number still submit paper forms—and risk being penalized under HMRC’s strict enforcement policy. The tax agency’s rules are clear: missing the paper deadline triggers an immediate fine, regardless of circumstances.
Thousands Penalized Each Year For Minor Delays
Data released by HMRC for the 2022/23 tax year revealed that 20,000 individuals received an automatic £100 fine for submitting their return just one day after the deadline. According to Birmingham Mail, many of these taxpayers were caught off guard, assuming the timeline was more flexible.
Even more concerning, 8,000 of those individuals saw their fines increase drastically over time—accumulating penalties of £10 per day, up to a maximum of £900. This financial burden is applied on top of any tax owed, creating serious consequences for late filers who may already be struggling.
Andrew Bartlett, chief executive of Advice Direct Scotland, issued a strong warning:
For those who still fill out a paper tax return, it’s important not to miss this key end-of-October deadline set by HMRC.
If you do, you risk incurring a fine on top of any tax that you might owe from the 2024/25 tax year.
The gap between the paper and digital submission windows is not always clear to taxpayers. The paper return deadline of October 31 is several months earlier than the digital self-assessment deadline, which falls on January 31, 2026. Bartlett emphasized this discrepancy, urging people to act early.
The deadline for paper returns is several months earlier than the cut-off date for the online version, so we want to help people get their returns in on time and avoid unnecessary fines.

Labour Government Under Pressure Over Rigid Penalty System
The current penalty structure comes under the administration of the Labour Party government’s tax arm, with HMRC acting as the enforcement authority. Despite mounting criticism from financial experts and taxpayers’ groups, there are no signs that HMRC plans to soften its approach.
Critics argue that the rigidity of the paper deadline disproportionately affects older individuals or those without reliable internet access. Meanwhile, HMRC maintains the early cut-off is essential to ensure enough time to process paper forms before the online deadline hits.
