Money Saving Expert Martin Lewis has issued a warning to millions of people across the UK that they could be facing a £100 fine for one simple mistake.
When discussing the deadline for tax self-assessment forms on his ITV show on Tuesday, the money expert shared that people could be fined £100 if they miss the January 31 cut-off date.
Martin urged people not to leave the form till the last minute, due to the risk that it could be clogged into the HM Revenue and Customs (HMRC) backlog.

Bracknell News reports that the warning affects those who are self-employed, with an income of more than £1,000 - or if HMRC have said you underpaid on tax last year.
It also includes people who are high earners, earned income from abroad, or earned money on savings and investments.
People could receive a £100 late filing penalty if the tax return is up to three months late - regardless of if you have any tax to pay back or not.
You will then receive a further £10 each day it is late over three months - adding up to £900. This means that the total fine could reach up to £1,000.
Martin said: "If you have been sent one, even if you don't think you should have, you have to fill it in and ask them not to send you once again next year.
“Do not leave these to the last minute. There are reports from MPs that the HMRC helpline is clogged and taking a long time to answer.
“The later you leave it, the more at risk you won't be able to get your questions answered and the more you're going to miss that deadline."
