Nurses, hairdressers and construction workers are among millions of employees being urged by HM Revenue and Customs (HMRC) to go online and directly check if they can claim extra cash back.

Employees could be missing out on their full tax relief entitlement for work-related expenses, by using agencies rather than claiming online.

Some 85 per cent of eligible taxpayers currently pay agents to claim their money. But those who are paid through Pay As You Earn (PAYE) could claim the full amount of tax relief they are owed directly from HMRC. A simple Check if You Can Claim tool is available at: https://www.gov.uk/tax-relief-for-employees 

If eligible, customers can log in to their Personal Tax Account to claim for their tax relief online and, if their claim is approved, be paid within three weeks.

Angela MacDonald, director general of customer services, said: "This is the easiest and quickest way to claim back tax relief on expenses and I'm delighted more and more workers are doing it directly online with HMRC at GOV.UK

"Tax relief isn't available for all employment expenses, which is why the online Check If You Can Claim tool is so handy - you can be reassured your claim will be approved and your full tax relief will be paid directly in to your bank account.

"We know what a difference tax relief can make to hard working customers, which is why we're keen to make sure they get all the relief they're entitled to by using our online service."

The majority of claims are for repairing or replacing tools and branded uniforms, professional subscriptions and mileage. Healthcare workers, people in food and retail and those in the construction industry are among the top professions to claim from HMRC.

Customers may be able to claim tax relief on the cost of:

• repairing or replacing small tools needed to do their job (for example, scissors or an electric drill)
• cleaning, repairing or replacing specialist clothing (for example, a branded uniform or safety boots)
• business mileage (not commuting)
• travel and overnight expenses
• professional fees and subscriptions
