Nearly 800,000 people who worked from home during the coronavirus pandemic have requested tax relief on their household-related expenses so far this tax year.
HM Revenue and Customs (HMRC), which released figures from its online complaints portal, said the saving was £ 125 per year per employee.
The relief can be backdated for four years, which is a total maximum claim of £ 500.
Eligible workers can claim the right for the entire year if they have been invited to work from home by their employer, even if it was only one day in the tax year.
The new fiscal year began on April 6, with over three million tax relief requests already received for fiscal year 2020/21.

Myrtle Lloyd, general manager of customer service at HMRC, said: “More and more people are returning to the office to work now, but it is not too late to ask for tax relief on household expenses if they have. worked from home during the pandemic. “
As of April last year, the maximum amount employers could pay tax-free without employees having to provide proof of a higher bill has been set at £ 6 per week.
Employees who have not received payment for work-at-home expenses directly from their employer may apply for HMRC tax relief.
Eligible customers can claim tax relief based on the rate at which they pay tax.

Over the course of the year, this means people can reduce the tax they pay by £ 62.40 or £ 124.80 respectively.
The HMRC said it would accept backdated requests up to four years and people could receive a lump sum payment for any successful backdated requests.
