Working from Home Tax Relief – what you need to know

Homeworking has become the norm for millions of people following the pandemic. But the rules on claiming tax relief for additional household costs you incur when working from home have changed. So read on to find out if you’re still eligible to claim up to £140 per year and whether can you still backdate your claim.

What is the Working from Home Allowance?

The government introduced working from home tax relief in 2003 to allow for anyone working from home to claim back some tax to help cover the increased household costs associated. This used to add up to a £4 a week tax-free sum.

However, because the pandemic forced millions more people to work from home, the government upped the amount to £6 a week. And the rules were also temporarily changed so you didn’t need to prove that you worked from home regularly. Instead, it meant you could claim up to £140 per year even if you only worked from home for one day.

But with all covid-related financial measures now removed, millions of workers are now back in the office either full time or part time. And in response, HMRC has updated its guidance for the 2022-23 tax year and introduced criteria that makes it harder to get a tax rebate for working from home.

Working from home tax relief: What has changed?

The eligibility criteria for the working from home tax rebate is different depending on which tax year you are claiming for.

For the 2020-2021 and 2021-2022 tax years you’ll need to meet the following criteria to be eligible for working from home tax relief. You can claim for these tax years if:

• Your employer told you to work from home.
• Your household costs increased because of working from home.
• And your employer did not pay you expenses to cover the extra costs associated with working from home.

You can backdate claims for the working from home allowance, so there is still time to claim for both the 2020-21 tax year and the 2021-22 tax year.

However for the 2022 – 2023 tax year the working from home tax relief eligibility rules have changed. The new rules state you can’t claim tax relief if you ‘choose to work from home’. This includes if your contract lets you work from home some or all of the time, if you work from home because of Covid or if your employer has an office, but you cannot go there sometimes because it’s full.

But some people will still be able to make a claim with the HMRC working from home allowance applying if your job requires you to live far away from your office. Or if your employer doesn’t have an office.

You can’t claim working from home tax relief if you are self-employed. Instead, though you can include some expenses on your tax return.

How to apply for the working from home allowance

HMRC have set up a specific online portal where you can claim working from home tax relief. You can find it at www.gov.uk/tax-relief-for-employees/working-at-home.

The portal starts off by asking you a series of question to check you are eligible for the working from home allowance. And it states clearly that different eligibility criteria apply to different tax years.

After that you will need your Government Gateway user ID and password to make your claim. If you don’t already have a user ID, it takes a few minutes to create one.

Once you’ve logged in, you need to give the date of when you started working from home. If this was the start of the first lockdown back in 2020, the date will be 23 March 2020. You can then claim the working from home tax allowance for the entire 2020-21 tax year plus the two weeks before. This is because the new tax year starts on 6 April, but lockdown started on 23 March. You can also claim for the 2021-22 tax year at the same time and the 2022-2023 tax year if applicable.

If you pay your tax via self-assessment, you can’t claim the working from home allowance through the portal. Instead, you’ll need to apply via your tax return.

How much tax relief can I claim?

The working from home allowance is designed to cover the extra costs you incur when you work from home rather than heading off to the office. It can be tricky working out exactly how much of your heating or electricity bill is associated with the time you were at your desk so there is essentially a flat rate of £6 a week you can claim.

You can get this payment in two ways:

• Your employer can pay it: You can get an extra £6 a week tax-free through your salary.
• You can claim tax relief on it from HMRC: If your employer won’t pay you the allowance, but you have or had extra unavoidable costs due to working from home, you can deduct the amount from your taxable income. You then claim tax relief on it from HMRC.

Tax relief on £6 a week adds up to:

• £1.20 a week for basic rate taxpayers, or £62.40 a year
• £2.40 a week for higher rate taxpayers, or £124.80 a year
• £2.70 a week for additional rate taxpayers, or £140.40 a year

If your home working costs add up to more than £6 a week you can claim tax relief for a larger amount. However, you will have to provide evidence to the taxman of what your costs were, such as receipts, bills or contracts. You must also prove these costs were directly connected to your employer’s requirement for you to work from home.

Can I still make a backdated claim?

HMRC says it will continue to accept backdated claims for people who have not yet claimed stating that taxpayers will receive a ‘lump sum payment’ for any successful backdated claims. It also stated that taxpayers have until the 5 April 2025 to make claims for 2020-21 tax year, and until 5 April 2026 make claims for 2021-22.

If you want to make a backdated claim you can do this via HMRC’s Working from Home Allowance portal.

How will I get the money?

If you are claiming for 2022-2023 tax year HMRC will adjust your tax code, and you’ll receive the tax relief through your salary.

And tax experts are urging employees who have previously made a claim to check their PAYE tax codes because if HMRC has included the relief and you are no longer eligible then you could get a surprise tax bill.
