People who work from home could get as much as £700 a year back from HMRC if they backdate a tax allowance they are owed for the past four years as well as this year.

The self-assessment tax return deadline from HMRC means that today is the last chance to submit a claim for working from home for the 2023-2024 tax year if you normally file a tax return.

And within that, there is a way to claim back £6 a week if you have to work from home, which you claim as part of your

But if you miss today's deadline, don't worry, as you can still make a claim in future and backdate the claim for another four financial years.

The allowance helps meet the cost of , heating, or broadband incurred by working from home.

If you don't submit a self-assessment , you can still claim the money back directly from via the gov.uk website, .

But the catch is that you're only eligible if you have to work from home, such as if your employer makes you work from home or you live too far from the office to be able to commute in.

If you choose to work from home, you won't be eligible for the tax relief.

The Government explains: "You may be able to claim tax relief for additional household costs if you have to work at home for all or part of the week.

"You can claim tax relief if you have to work from home, for example, because your job requires you to live far away from your office; your employer does not have an office.

"You cannot claim tax relief if you choose to work from home. This includes if your employment contract lets you work from home some or all of the time; your employer has an office, but you cannot go there sometimes because it's full."

So, you wouldn't be eligible for the money if you have a permanent working-from-home contract.

The taxman will let you claim either the exact amount you spent on phone calls, gas, and electricity for work or a flat £6 a week rate, which would equal £312 across a full year. Your tax would then be taken off at your income tax rate up to £140. If you claim for the current tax year and the four past years, that's £700 in tax relief you could get.

The Government adds: "You can only claim for things to do with your work, such as business phone calls, gas and electricity for your work area. You cannot claim for things that you use for both private and business use, such as rent or broadband access.

"You can claim for this tax year and the four previous tax years."

You will then get tax relief based on your current income tax rate.
