The deduction rates are set by Schedule 4 of the Council Tax (Administration and Enforcement) Regulations 1992. They are based on your net earnings and apply as fixed percentage bands. For monthly-paid employees, the current rates are:
- Net earnings up to £300 per month: 0% (no deduction)
- £300 to £550: 3%
- £550 to £740: 5%
- £740 to £900: 7%
- £900 to £1,420: 12%
- £1,420 to £2,020: 17%
- Over £2,020: 17% on the first £2,020, then 50% on any amount above that
For weekly-paid employees, the equivalent bands apply: no deduction below £75 per week, rising to 17% between £355 and £505, and 17% plus 50% on earnings above £505.
These percentages can take a serious chunk out of your take-home pay. If you earn £1,800 per month net, for example, 17% means losing £306 each month. If deductions leave you unable to cover rent, food, or other essential bills, you need to act quickly.
