Workers forced to work from home while they self-isolate after getting 'pinged' by the NHS Test and Trace app can claim up to £125 tax relief for 2021-22.
Rising Covid-19 cases meant more than 600,000 people were contacted by the app between 8 and 14 July, meaning thousands of people may be having to work from home during their self-isolation period.
Recent figures from HMRC revealed that more than 550,000 workers have already made their claim since the new tax year began on 6 April 2021 - but many more could be eligible as you can claim even if you have to work from home for just a day.
Here, Which? explains how to claim the tax rebate and how to get further financial help to power your home while you're working.
First, you'll need to check whether or not you're eligible to receive tax relief for working from home. To claim, you must:
If all of these apply to you, then you can head to the , where its eligibility tool will check all of the facts. You'll need a Government Gateway user ID and password to proceed, but if you don't already have one you'll be guided to the right place to make one.
Once you're logged in, you'll need to state what date you started working from home. You'll receive a rebate for the full tax year, even if you don't know what date you'll be going back to the office - and even if you've only worked from home for one day.
The tax relief you'll receive depends on your income tax band.
All taxpayers can get a flat rate of tax relief on £6 a week; basic-rate taxpayers will gain £1.20 a week (20% of £6), which equates to £60 a year.
Higher-rate taxpayers can gain £2.40 a week, which is 40% of £6 and equates to £125 a year.
The government's microsite allows you to tick boxes for the current and previous tax year, meaning it's possible to get £120 or £250 if you didn't claim last year.
Further to this, HMRC says it will accept backdated claims for up to four years - as the working from home order was first brought in towards the end of the 2019-20 tax year, you will also be able to claim for that, too.
If you have already made claims for previous tax years, you'll still have to make a new claim for 2021-22.
If the standard tax rebate doesn't cover enough of the extra things you've had to pay for to work from home, it's possible to make a claim for more, but you'll have to provide evidence of your increased outgoings.
What you can claim also differs depending on whether you're employed or self-employed.
Employed workers can only claim tax relief on expenses that are solely used for work purposes.
This can include things such as extra energy costs to power your work area, or the cost of business calls that have been added to your phone bill.
However, you can't claim for things that are used for both private and business use, such as rent or broadband.
Self-employed workers can claim for more costs when working from home, such as a proportion of the costs when lighting, heating, cleaning, insurance, mortgage interest, water rates and general maintenance are used for work.
To work out the proportion, you'll need to account for the amount of time you're using your home for work, and in some cases the size of the area within the home that's used for work purposes. For example, if you work in a study you'd only be able to claim for the costs of heating that room while you work.
Expenses incurred from working from home can be deducted from your profits, which will reduce your overall tax bill.
