Martin Lewis urged people to fill in their tax self assessment form as soon as possible.
The consumer champion issued the advice on last night's edition of Money Show Live. The first episode of the year was an annual bill-busting special as he provided financial tips amid the ongoing cost-of-living crisis.
The final segment of the show tackled news you can use and Martin urged people to be aware of the upcoming tax self assessment deadline on January 31. He said: "If you miss it, you get a £100 fine and if you don't pay on time then you can also be charged interest on late payments."
