Get Ahead of the 31st January Tax Deadline
14 October 2025
Reminder: 31st January Self-Assessment Deadline
As the 31st January self-assessment deadline approaches, we are reminding all our clients to provide their personal tax information to us as early as possible. Submitting your details in good time means we can prepare and file your return without the last-minute rush, ensuring complete accuracy and giving you peace of mind.
Why leaving it late can be costly
HMRC impose strict penalties for late filing:
-
A £100 fixed penalty applies immediately if your return is late, even if you have no tax to pay.
-
After three months, you face additional daily penalties of £10 per day (up to £900).
-
At six months, a further £300 or 5% of the tax due (whichever is higher) is added.
-
At twelve months, another £300 or 5% of the tax due can be charged, with even harsher penalties in serious cases.
Autumn Budget — possible changes
With the Autumn Budget around the corner, we may also see changes that affect allowances, reliefs, and liabilities. Getting your return sorted now means you can plan ahead with clarity, rather than being caught off guard by any adjustments announced later in the year.
Advantages of providing your information early
Providing your information early has other advantages too:
-
Smoother process – No rushing, no stress, and more time for us to check every detail.
-
Cashflow planning – You’ll know your tax liability well in advance, allowing you to budget for January.
-
Peace of mind – You can enjoy the holiday season without the looming worry of an unfinished tax return.
Our message
Our message is simple: don’t wait. The earlier we receive your paperwork, the sooner we can ensure your return is filed accurately and on time, protecting you from unnecessary penalties.
