“the tax year 2019-20 before the period of furlough began”
“To work out 80% of the average monthly wages for the last tax year: 1. Start with the amount they earned in the tax year up to the day before they were furloughed. 2. Divide it by the number of days from the start of the tax year – including non-working days (up to the day before they were furloughed, or5 April 2020 – whichever is earlier) 3. Multiply by the number of furlough days in this pay period. 4. Multiply by 80%.”
