What Happens to Council Tax When You Move House?

Moving house triggers a number of admin tasks — and council tax is one of the most important, and most frequently handled incorrectly. Many people either forget to notify their old council, fail to register at the new address promptly, or move into a new property without ever checking whether the band is correct. This guide covers exactly what you need to do, and when, to avoid unexpected bills or missed refunds.

Notifying Your Old Council

As soon as you have a confirmed moving date, contact your current local council to tell them you are leaving. Most councils have an online form for this — search for “[your council] council tax moving out” or use the council's website.

You will need to provide:

• Your current address and account reference number (on your council tax bill)
• Your moving out date
• Your forwarding address (so they can send any final bill or refund)

Your council tax liability at your old address ends on the day you vacate the property — not on completion day if those differ. If you are a tenant and your tenancy ends on a specific date, that is typically your last day of liability.

If you have been paying by direct debit, cancel it only after you receive your final bill and confirm any balance. Cancelling too early can leave arrears.

Registering at Your New Address

Contact your new local council as soon as you move in — ideally on moving day or within a few days. If you delay, your liability still starts from the day you moved in, so delaying registration just means a larger backdated bill when you eventually register.

Most councils have an online form for moving in. You will need:

• Your new address
• Your moving in date
• The names of all adults living in the property
• Whether any discounts apply (single person discount, student exemption, etc.)

If you have moved to a new council area, you will be dealing with a different council from your old one — you need to contact both separately. They do not automatically share information.

Check Your New Band Before You Pay

This is the step most people skip — and it can be expensive.

Before you set up your direct debit at the new property, check the council tax band against neighbouring properties. Your new home may have been in the wrong band for years, and the previous owner either never noticed or never challenged it. That is not your problem — except that once you are paying the bill, the overpayment becomes yours.

Use TaxBandCheck to check your new address. Enter the postcode and compare your band against similar properties on the same street. If you see Band E on your property and several Band D properties of the same type and size nearby, you have a potential case worth investigating.

If you challenge the band successfully after moving in, your refund runs from your move-in date — not from when the original error was made. The previous owner would need to make their own claim for the years they overpaid. So the sooner you check and challenge, the more you can recover. For typical refund figures, see our guide on how much council tax refund you can get.

What Happens If There's an Overlap?

If you own both properties simultaneously — for example during a period between exchange and completion, or if you are buying before your old property has sold — you may be liable for council tax on both.

Most councils offer a short empty property discount (often 100% for the first month) on a property that is genuinely empty. Contact your old council to apply as soon as the property is vacant.

If the overlap period is longer, there is no automatic relief — you pay on both properties unless an exemption or discount applies.

What About Completion Day vs Moving Day?

For buyers, council tax liability at the new property starts on completion day — the day you legally become the owner — even if you do not physically move in until later. This catches some buyers by surprise.

If there is a gap between completion and moving in, contact the new council immediately after completion to register, and ask about an empty property discount for the gap period.

For renters, liability starts on the first day of your tenancy — again, even if you do not physically move in immediately.

Council Tax Refunds When Moving Out

If you have been paying by direct debit and move out partway through the month, you will likely have overpaid. Your council will calculate the exact amount owed up to your moving out date and refund the difference — either by cheque or bank transfer to the account on file.

This is separate from any band challenge refund. The moving-out refund is simply a reconciliation of payments made vs liability incurred. It is automatic — you do not need to claim it, but you do need to provide a forwarding address so the council can reach you.

Moving house is one of the most common triggers for discovering a council tax anomaly. You are looking at a new property with fresh eyes, comparing it to neighbours you have just met, and often researching the area thoroughly before buying. If something looks off about the band — check it. The cost is nothing, the process is straightforward, and the potential refund can be substantial.
