Working from home portal for employed staff

HMRC have launched their portal for employees who have to work from home and can claim the £6 per week tax allowance.  For employees to be able to do this, the employer must confirm the employee has to work from home and there is no choice in the venue for the employee.  To access this portal please click here and follow the green ‘check if you can claim’  https://www.gov.uk/tax-relief-for-employees/working-at-home
