Reduction overpayments and appeals

Understanding council tax overpayments and how to appeal

About overpayment

An overpayment is an amount of Council Tax Reduction you have received, but are not entitled to.

Overpayments usually happen following a change, and where we have not been notified in time to revise your benefit entitlement. For example, if your income has increased.

If you have a change in your circumstances, it's important to let us know straight away.

We will send you a new Council Tax bill which will include the overpaid Reduction. We will let you know the cost of the new instalments.
