How to find your Council Tax account number and online key
Account number
You can find your account number:
- on your paper bill
- on any other letters we send to you about your account (reminder notices or final notices)
- on your bank statement or online banking, if you pay by Direct Debit or standing order
- by signing in to your existing online Council Tax account
If you live in the Chiltern or South Bucks areas your account number will have recently changed. Your new account number will be on your Council Tax bill dated March 2023.
Online key
Your online key is needed to register for an online Council Tax account for the first time.
The online key can be found on the latest bill or recovery notice that we have sent you.
You must look at the latest notice or bill issued as the key will change for security reasons until you have created an online account.
The key is case sensitive so must be entered exactly as shown.
Example: Council Tax bill
You can find your Council Tax account number and online key on any correspondence we send you.
The account number is 8 or 10 digits long and is shown at the top of your annual bill.
The online key is 10 letters long and is shown at the top right of your bill.
