Launched on October 1, the online portal is simple to use and has been set up to process tax relief on additional expenses for employed workers who have been told to work from home by their employer to help stop the spread of coronavirus.

From 6 April 2020, employers have been able to pay employees up to £6 a week tax-free to cover additional costs if they have had to work from home.

Employees who have not received the working from home expenses payment direct from their employer can apply to receive the tax relief from HMRC.

Eligible taxpayers can claim tax relief based on the rate at which they pay tax. For example, if an employed worker pays the 21% intermediate rate of tax and claims tax relief on £6 a week, they would receive £1.26 a week in tax relief (21% of £6 a week) towards the cost of their household bills.

Higher rate taxpayers would therefore receive £2.46 a week (41% of £6 a week). Over the course of the year, this could mean taxpayers can reduce the tax they pay by £65.52 or £127.92 respectively.

Karl Khan, HMRC’s interim director general of customer services, said: “We want everyone to get the money that they are entitled to, so we’ve made the online service as easy to use as we can – it takes just a few minutes to make a claim.”

Once the application has been approved, the online portal will adjust an individual’s tax code for the 2020 to 2021 tax year. The employee will receive the tax relief directly through their salary and will continue to receive the adjustment until March 2021.

HMRC is also reminding employed workers, for example healthcare workers and care home staff, that they can also claim tax relief on work-related expenses, including cleaning their work uniforms.

The extra money can help thousands of critical workers whose efforts are helping save lives during the coronavirus pandemic.

Employees who clean, replace or repair uniform or tools, or pay fees and subscriptions for their work can apply online directly to HMRC and see instantly if they are eligible for tax relief on work expenses.
