HMRC gives taxpayers major 100-day warning | Personal Finance | Finance

HM Revenue and Customs (HMRC) has warned members of the public who file their tax returns through Self Assessment only have 100 days left to do it. The deadline is 31 January next year, with the UK’s tax authority urging people to send off the return early.

It says those who file early know how much tax is owed sooner, meaning they get more time to prepare to pay their bill by the deadline.

Myrtle Lloyd, HMRC’s chief customer officer, said: “With 100 days to the Self Assessment deadline, now is the time to get started. Completing your return now means you know how much tax you need to pay ahead of the deadline.

“We are here to help with lots of help and advice, just search ‘file a tax return’ on GOV.UK to find out more.”

Those who start their return early can go back to it as many times as they need to before submitting it, HMRC added.

So far, 3.5 million people have filed their Self Assessment tax return for the 2024 to 2025 tax year.

HMRC is encouraging those unsure whether they need to fill in a tax return for the period to use the Self Assessment Checker tool on Gov.uk. People can also register and notify HMRC if they no longer need to complete one through the website.

More than 97% of tax returns last year were filed online. Self Assessment is a system HMRC uses to collect income tax.

On its website, HMRC says people must send a Self Assessment 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 had to pay Capital Gains Tax when you sold or ‘disposed of’ something that increased in value

• You had to pay the High Income Child Benefit Charge and do not pay it through PAYE
