Missed the Tax Return Deadline? What Happens Now?

[Updated 1 February 2026]: If you missed the 31 January deadline to submit your self-assessment tax return, you are now into the penalty stage. HMRC applies an automatic £100 penalty to those who are anywhere from 1 day to 3 months late. Further penalties are then added if you take even longer to comply. It’s even worse if you haven’t paid the tax owed to HMRC by 31 January because you’ll then owe interest on that too. Here’s our professional advice of what to do if you’re late…

We’re Open on Sunday 25 January 2026 — Beat the Tax Return Deadline!

/in , , , , , , , /by

Taxfile is open this Sunday 25 January 2026 as well as Mondays to Saturdays throughout the month.

With the self-assessment tax return deadline almost upon us, we are opening our Tulse Hill office* this Sunday, 25 January 2026, from 10 am to 5 pm by appointment. That’s in addition to Saturdays, which will remain open, by appointment, for the remainder of January (9 am-5 pm on 24 January) and, of course, weekdays opening hours as usual (see footer). A weekend appointment may be the perfect opportunity to discuss your tax return with us or bring in figures and records without having to disturb your working week. Weekend time slots are limited, though, so please book a free 20-minute appointment as soon as possible if you’d like to visit.
