Millions of people have just ten days to act, or risk a £100 fine of HMRC which could later become a considerably higher sum.
The government department said around 5.7 million people are due to file a tax return by January 31. Anyone who doesn't do so by this time risks being hit with a £100 penalty, even if they don't owe any tax.
Myrtle Lloyd, HMRC’s Director General for Customer Services, said: "My message to those yet to start is: don’t delay, do it online. HMRC provides lots of useful information to help you get started. Visit GOV.UK and search ‘Self Assessment’."

Gov.uk advice adds: "HMRC is warning customers that the deadline to submit a paper return has passed and tax returns can only be submitted online. Anyone who files after 31 January may face a penalty."
Who needs to complete a tax return?
You must send a tax return if, in the last tax year (6 April to 5 April), any of the following applied:
- you were self-employed as a ‘sole trader’ and earned more than £1,000 (before taking off anything you can claim tax relief on)
- you were a partner in a business partnership
- you earned £100,000 or more
You may also need to send a tax return if you have any untaxed income, such as:
- some Covid-19 grant or support payments
- money from renting out a property
- tips and commission
- income from savings, investments and dividends
- foreign income
After the initial £100 penalty, people can expect to be charged a further £10 for every day their tax return is late.
