Council Tax Discount and Instalment Planner
Plan council tax payments using the annual charge from your council. Apply a confirmed discount, account for the days you are liable and see how the balance could be spread across remaining instalments.
Calculation breakdown
How to use this tool
- Enter the full annual charge and bill year.
- Add only discounts you have confirmed or clearly label a scenario.
- Enter liability dates and payments already made.
How the result is calculated
The planner applies the selected discount to the charge, adjusts for the supported liability period and subtracts payments before splitting the balance.
Worked example
A £2,000 annual bill with a confirmed 25% discount becomes £1,500. Spread over ten equal instalments, that is £150 per instalment.
What this result does not cover
Your council determines eligibility, billing dates and the final bill. This version does not calculate Council Tax Reduction benefits or support Scottish and Northern Irish billing.
