Do HMRC still accept paper tax returns.

Yes, HMRC still accepts paper tax returns, but they strongly prefer and actively encourage digital filing.   

Here is what you need to know if you're deciding between paper and online:

Key Differences & Deadlines

• Strict Paper tax return Deadline (31 October): The deadline for submitting a paper Self Assessment return is 31 October following the end of the tax year a full three months earlier than the online filing deadline of 31 January.   

• No Automatic Paper Forms: HMRC no longer routinely sends out paper return forms (SA100) by post. If you need a paper copy, you must download it from GOV.UK or request one by calling HMRC.   

• Longer Processing Times: Paper returns require manual processing and data entry, which typically takes 6 to 10 weeks (or longer during peak periods), compared to 1 to 2 weeks for online submissions.   

• Making Tax Digital (MTD): Under HMRC's ongoing digital transformation, businesses and sole traders above certain income thresholds are gradually being required to keep digital records and submit updates digitally via compatible software rather than on paper.

Who must File a Paper tax return (or Use Special Software)?

While most individual taxpayers can choose between paper and HMRC’s standard online service, a few complex scenarios cannot be submitted using standard HMRC online services (they require specialized commercial software or paper forms):

• Trust and estate returns (unless using third-party software)   

• Ministers of religion   

• Lloyd’s underwriters   

If you do send a paper return, it is best to post it via a tracked service or obtain proof of postage at the Post Office to ensure you can prove it arrived before the 31 October deadline.
