TL;DR: Council Tax follows occupation, not tenancy dates. You are liable at a property from the day you move in and until the day you move out. In most moves, there is a clean switch date. In cases where tenancy dates don't align, the test is your actual main residence on any given day. Notify both councils of the exact move dates - if you overpay at either, request a refund. Double liability for the same period is not intended by the legislation.

The Fundamental Rule: Council Tax Follows Occupation
The starting point is section 6 of the Local Government Finance Act 1992, which determines who is the liable person for Council Tax based on who resides at or owns a property. The key principle is factual residence - where you actually live, not necessarily what dates your contracts say.
This means:
- You become liable at the new property from the day it becomes your main home.
- Your liability at the old property ends on the day it ceases to be your main home.
In most moves, these two dates coincide - you hand back keys at the old place and receive keys at the new place on the same day. The liability switches cleanly.
The Tenancy Date Alignment Problem
Many home movers face overlapping or gapped tenancy dates:
Overlapping tenancy scenario: Your old tenancy officially ends on 31 July. Your new tenancy starts on 1 July. Both tenancies run for the same 31-day period. Are you liable at both?
Answer: No. You can only have one main residence. During this overlap month, your main residence is the property you are actually living in. If you move your possessions and live at the new property from 1 July while your old tenancy technically continues, the new property is your main residence from 1 July. Your Council Tax at the old property should end on 1 July (or whenever you actually stopped occupying it as your main home). Notify both councils of the actual move date.
Gapped tenancy scenario: Your old tenancy ends on 31 July. Your new tenancy starts on 5 August. You spend 4 nights in a hotel or with family. Who is liable for Council Tax during the gap?
Answer: If your old property is vacant from 1 August, the landlord is typically liable from 1 August (as the non-resident owner) for the empty period. Your Council Tax liability at the old property ended on your actual move-out date (31 July). At the new property, your liability begins on 5 August when your tenancy starts and you move in.
Exchange and Completion: The Property Purchase Cutover
For property buyers and sellers, the cutover date is completion:
The seller's Council Tax: Ends on the completion date. From completion, the seller has no further Council Tax liability at the sold property.
The buyer's Council Tax: Begins on the completion date. The buyer is the owner from completion and therefore the liable person for Council Tax at that address from completion day.
Between exchange and completion: After contracts are exchanged but before completion, the property is still owned by the seller. The seller remains liable for Council Tax (if they are still living there or if it is vacant and they are the non-resident owner). The buyer has no Council Tax liability until completion even if they have paid their deposit and are legally committed to purchase.
Chain delays: If completion is delayed (a common occurrence in property chains), the existing liable person (seller, landlord, or previous occupant) remains liable until completion. The buyer cannot take possession early and cannot be liable for Council Tax at the property before completion.
The Landlord Liability Gap Between Tenancies
When a tenant moves out and the property is temporarily vacant before a new tenant moves in, the landlord becomes the liable person for the empty period.
Most billing councils do not charge Council Tax for vacant properties during the first period of vacancy (the empty property discount or 0% charge varies by council policy post-Local Government Finance Act 2012). Some councils charge from day one of vacancy; others grant a short exemption period.
Landlord planning for void periods: A landlord between tenants should:
1. Notify the billing council of the tenancy end date.
2. Ask about the council's empty property policy (0%, discount, or full charge from day one).
3. Ensure the new tenancy start date is notified promptly to end the landlord's void period liability.
The Double-Payment Risk
A common problem in moves is double payment:
Scenario 1: Old council keeps charging by Direct Debit after move-out because the tenant forgot to notify them. New council charges from move-in. Tenant pays both.
Resolution: Notify the old council of move-out date immediately. Claim refund of any overpayment after the move-out date. Most billing councils process refunds within 4 to 6 weeks.
Scenario 2: Landlord charges "Council Tax is included in rent" but the billing council has registered the tenant as liable. Tenant pays rent (which includes CT) and separately pays the CT demand.
Resolution: Determine who is registered as the liable person with the billing council. If the landlord has agreed to pay Council Tax as part of the rent, the landlord should be managing the billing directly. The tenant should not be paying separately to the billing council.
The Legal Test for "Main Residence" During Overlaps
When there is genuine uncertainty about which of two properties is the main residence during an overlap period, the test under the Local Government Finance Act 1992 (section 6) is factual:
- Where do you sleep most nights?
- Where are your possessions?
- Where do you receive post?
- Where are you registered?
The billing council makes a factual determination if there is a dispute. In practice, if you notify both councils clearly with the exact move date and explain that you physically moved on that date, both councils will accept the move date as the switch point.
What To Do In Practice
1. Decide on your actual move date - the day you physically move from old to new.
2. Notify the old billing council of your move-out date within 21 days.
3. Notify the new billing council of your move-in date within 21 days.
4. Provide both dates to both councils - the old council needs the move-out; the new council needs the move-in.
5. Cancel the old Direct Debit once you receive the final account statement from the old council.
6. Set up a new Direct Debit with the new billing council.
If you find after the move that you have been charged at both addresses for the same period, contact the council that has charged incorrectly (the one where you did not actually reside during the overlap) and request a refund with evidence of your actual move date.
Temporary Storage and Moving Day Complexity
One practical complication for many movers is that physical removal takes time - furniture may be moved over several days, and boxes may be stored temporarily. For Council Tax, the relevant question is when you legally established your new main home, not when every box was unpacked.
The move-in date is the day you take up residence - typically the first day you sleep at the new property. It does not require everything to be unpacked or all belongings to have arrived. Most billing councils accept the first day of occupation (when you take possession of the keys and start using the property as your home) as the move-in date.
Storage units: If you use a storage unit between homes, this does not affect Council Tax. Storage units are not residential properties and do not create any Council Tax liability.
New builds with delays: When a new build has a delayed completion, the buyer's Council Tax liability at the new property does not start until completion. If the buyer is also selling and has vacated the old property before the new one is complete, there may be a short period where neither property is the buyer's main residence - the billing council at the old address should be notified of the vacancy and standard empty property rules apply.
Frequently Asked Questions
My old tenancy runs until 31 August but I moved out on 1 August - am I liable for August at the old address?
No. If you moved out on 1 August and it ceased to be your main residence from that date, your Council Tax liability at the old address ends on 1 August. The fact that your tenancy continues until 31 August does not extend your Council Tax liability if you are not occupying it as your main home. Notify the billing council of your actual move-out date (1 August) and they should adjust your bill accordingly.
I'm selling my house and buying simultaneously - what happens on completion day?
Your seller liability at your current home ends on completion day. Your buyer liability at the new home begins on completion day. Most billing councils treat completion day as belonging to the buyer for Council Tax purposes - you pay at the new address from completion day and the seller stops paying from completion day. The exact day allocation (whether it is the seller's or buyer's day) can vary slightly by council practice.
My completion keeps being delayed due to a chain issue - am I still liable at the old address?
Yes. Until completion, you remain the liable person at your current property (as either the occupant or the non-resident owner if you have already moved out). The buyer has no liability until completion. Budget for the continuing Council Tax cost during chain delays.
I've been charged by both the old and new councils for the same month - what do I do?
This is a double-billing error. Contact both councils with your exact move date and request that one of them correct their bill. If you moved mid-month, the old council should charge for days 1 to move date and the new council for move date to end of month. If both are billing for the full month, one is wrong. Ask the councils to resolve between them or provide your move date evidence to both.
The estate agent says I can move in early before completion - who pays Council Tax?
If you move in before completion (which is legally problematic and unusual), the position is uncertain. You are not legally the owner yet, but you may be treated as a licensee (which is near the bottom of the liability hierarchy). The safest approach is to wait for completion. If an early move-in is genuinely agreed, seek clarity from the billing council on liability during that pre-completion period.
How we verified this
The Council Tax liability hierarchy and the main residence test are from section 6 of the Local Government Finance Act 1992. The 21-day notification requirement is from the Council Tax (Administration and Enforcement) Regulations 1992. The completion date as the transfer of liability for property purchases is from standard MHCLG guidance on Council Tax and property transactions. The IRRV provides professional guidance on overlap liability situations in practice.
