To be eligible, you must be carrying out the duties of their employment under homeworking arrangements. This means that the employee is regularly performing some or all of their duties at home.
HMRC guidance notes that they will accept an employee is working at home regularly where it is frequent, or follows a pattern, such as working at home for two days of every week. In the example of an employee working two days a week at home, HMRC will still consider it to be regular even if the employee varies the days which they work at home each week.
Informal working at home which is not by arrangement does not count as homeworking – for example taking work home in the evenings will not qualify the employee for tax-free reimbursement of costs. There must be an arrangement to work at home and not at the employer’s premises, and it is good practice for this to be in writing.
During the COVID-19 pandemic, HMRC will accept that employees working from home because their employer’s offices have closed - or because the employee is following advice to self-isolate - meet these requirements. Newly home-based employees will be eligible to receive the allowance tax free from the date that their employer agreed they could work from home, or from when the initial government advice to work at home was announced in March 2020.
