In case your worker’s tax code has ‘W1’ or ‘M1’ on the finish
W1 (week 1) and M1 (month 1) are emergency tax codes and seem on the finish of an worker’s tax code, for instance ‘577L W1’ or ‘577L M1’. Calculate your worker’s tax solely on what they’re paid within the present pay interval, not the entire 12 months.
Tax codes with the letter ‘K’
The tax deduction for every pay interval can’t be greater than half an worker’s pre-tax pay or pension.
