Don't miss today's self-assessment online tax return deadline

31 January 2017

If you’re filing your tax return online, you have until the end of today (31 January) to get everything sorted or face severe fines.

Those who need to submit a tax return for the 2015/16 tax year are generally the self-employed and anybody who earns extra income on the side that isn’t paid through a company pay as you earn (PAYE) scheme.

You may also need to submit a return if:

  • You’ve received more than £2,500 in untaxed income in the last year.
  • You get more than £10,000 from savings or investment income (excluding Isas).
  • You’ve sold investments that are liable for capital gains tax, for example, a buy to let property, or investments that don’t sit within an Isa or pension.
  • You’ve received income from outside the UK.
  • You’ve lived abroad while receiving an income from the UK.
  • You’ve been notified by HMRC that you’ve underpaid your taxes in previous years.
  • You’re a parent with an income over £50,000 and you’re also receiving child tax credits.
  • You’re a higher-rate taxpayer with a pension – as some employers only claim basic tax relief for you, you’ll need to claim higher rate relief yourself.


You can’t file for the 2015/16 tax year by paper as the deadline has long passed - it was 31 October 2016. However, it’s also worth keeping in mind that from 2020, all tax returns will need completing online.
