[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...

[Updated November 2025]: If you're self-employed in the UK and earn more than £1,000 after allowable deductions, you need to file a self-assessment tax return each year. It's not only the self-employed, though. If you are on a higher income* or receive untaxed income from things like property rental, tips, commission, savings, investments, dividends, or foreign income, you also have to submit a return. Partners in business partnerships and those who made a capital gain resulting in Capital Gains Tax (CGT) also need to submit a return.

If you do have to fill in a self-assessment tax return, getting all the tax return fields filled in properly and the figures right can sometimes be difficult. That's where professional help from companies like Taxfile is worth its weight in gold. But what information will your accountant or tax advisor need from you? In today's guide, we'll explain exactly what you'll need to supply.
