TL;DR: You must register for Council Tax at your new address as soon as you move in. The "liable person" is determined by a statutory hierarchy: owner-occupiers first, then tenants, then sub-tenants. Registration is through your local council's website or phone line. Councils backdate liability to your move-in date but do not impose penalties for honest delays. New builds must first be banded by the Valuation Office before a bill can issue.

Who Has to Register: The Liable Person Hierarchy
Council Tax liability does not automatically attach to whoever moves into a property. The Local Government Finance Act 1992, section 6, establishes a hierarchy of liable persons. The person highest in the hierarchy who is resident at the property is the liable person.
The hierarchy, from most to least liable, is:
1. Resident owner-occupier (a person who both owns and lives in the property)
2. Resident tenant (a person who lives in the property under a tenancy agreement)
3. Resident sub-tenant (a person who lives in the property under a sub-tenancy)
4. Resident licensee (a person with a licence to occupy but no tenancy)
5. Non-resident owner (where none of the above applies and the property is empty, the owner becomes liable)
In most private rental situations, the tenant (or tenants) is the liable person. The landlord is not liable while the property is occupied by tenants, unless the tenancy agreement makes specific provisions - but those provisions cannot override the statutory hierarchy.
Joint and several liability: Where two or more people occupy a property and are at the same level of the hierarchy (for example, two joint tenants), they are jointly and severally liable. This means the council can pursue any one of them for the full amount. It is then a matter for the liable persons to apportion payment between themselves. The council does not split the bill between joint tenants unless specifically asked to, and even then it may decline.
Co-tenants and lodgers: If you take in a lodger (a licensee), you as the tenant remain the primarily liable person. The lodger's presence does not transfer liability to them. However, having a non-disregarded adult lodger may affect your entitlement to the single person discount.
Step 1: Find Your Billing Council
Your billing council is the local authority responsible for collecting Council Tax at your new address. In England, this is either a district/borough council (in two-tier areas) or a unitary authority. In Wales and Scotland, it is your unitary authority or council.
The easiest way to find your billing council: go to gov.uk/find-local-council and enter your postcode. The result shows your billing authority and links to their website.
Be aware that in some two-tier English areas, the billing authority (district council) is different from the county council that provides many services. You register with the billing authority (district council), not the county council.
Step 2: Access the Council's Registration Form
From your billing council's website, navigate to the Council Tax section. Look for links labelled "Tell us you've moved in," "New resident," "Register for Council Tax," or "Moving home."
Most councils have a dedicated online form for new registrations. If you cannot find it on the website, look for "Contact us" and use the council's Council Tax enquiries email or phone number. Some councils accept registration by phone without an online form.
You will typically be asked to provide:
- Your full name (and all other adults in the household)
- Your date of birth (for identity verification)
- Your National Insurance number (in many cases)
- The address of the property you are registering at
- Your move-in date
- Your forwarding address from your previous property (so the council can close your previous account if it was in the same billing area)
- Contact details: email address and phone number
Step 3: Provide Evidence of Your Move-In Date
Some councils require evidence of when you moved in. Others accept your declaration without documentary evidence for initial registration. Common documents used as evidence include:
- Tenancy agreement: Shows the tenancy start date, which is typically the move-in date. If you moved in before the tenancy start date (for example, on a preparation day), make clear which date is the actual occupation date.
- Completion statement (for purchases): The legal completion date on the solicitor's completion statement is the date from which you are liable as an owner.
- Mortgage offer or completion letter: Can support the completion date.
- Utility connection letter: A gas, electricity, or water connection letter showing the date services were connected in your name supports the move-in date.
Keep these documents for at least one year after moving in, in case the council later queries the liability start date.
Step 4: Declare Other Adults in the Household
When registering, you must declare all adults aged 18 and over who live at the property. The council uses this information to determine whether any discounts apply:
- If you are the only adult, you may be eligible for the 25% single person discount.
- If any other adults are "disregarded" for Council Tax purposes (students, severely mentally impaired persons, apprentices, certain carers), they may not affect the discount - but you must still declare them and explain their status.
- If there are two or more non-disregarded adults, no single person discount applies.
Failing to declare other adults is a civil offence that can result in a penalty and recovery of any incorrectly applied discount.
How New Builds Get Registered for Council Tax
New-build properties enter the Council Tax system differently from existing properties. Before your billing council can issue a bill, the Valuation Office (formerly VOA, now part of HMRC since 1 April 2026) must assign a Council Tax band to the property.
The process typically works as follows:
The developer or your solicitor (on completion) notifies the billing council that the property has been completed and occupied. The billing council notifies the Valuation Office. The Valuation Office assigns a band based on the property's estimated April 1991 value, using comparable evidence (the "tone of the list" methodology for new properties).
The band assignment can take weeks to months. During this period, your billing council may issue an interim bill at an estimated band, or hold the bill until the band is confirmed. Once confirmed, the final bill is issued and any difference between the interim estimate and the confirmed bill is settled as a credit or charge.
If you are buying a new build, ask the developer whether the band has been confirmed before completion. Many developers provide an estimate, but this is not the same as a confirmed Valuation Office band.
What Happens If You Forget to Register
Failing to register for Council Tax does not absolve you of liability. The council can backdate your liability to the date you moved in once they become aware of the occupation - whether through electoral roll registration, utility company data sharing, or other means.
When a backdated bill is issued, you owe the full amount from your move-in date, including any months already elapsed. No penalty is applied for honest failure to register promptly, but you will be expected to pay the backdated amount.
This is not a criminal offence if the delay was accidental. However, if you deliberately avoided registering to avoid Council Tax liability, this can be treated as Council Tax fraud under the Fraud Act 2006.
The practical advice: register as soon as possible after moving in, ideally on your first day or within the same week. Council Tax is a statutory liability that applies from move-in regardless of registration.
The Tenant Deposit Scheme: Council Tax Is Not Covered
A common misconception among renters is that their tenancy deposit covers any outstanding Council Tax. It does not. The tenancy deposit scheme, administered by government-approved schemes (Tenancy Deposit Scheme, MyDeposits, Deposit Protection Service), protects deposits against damage to the property and unpaid rent as defined in the tenancy agreement. Council Tax is a statutory liability owed to the billing council - it is not a landlord debt that the deposit covers.
If you leave a property with unpaid Council Tax, the council pursues you personally through the statutory enforcement process. The landlord is not liable for your Council Tax (unless they are the liable person under the hierarchy because you have vacated and they are the non-resident owner of an empty property).
What If You Are a Student or in Shared Accommodation?
Full-time students are disregarded for Council Tax purposes and do not count as liable adults. A property occupied entirely by full-time students is exempt from Council Tax (Class N exemption). When registering for Council Tax at a student address, each student should provide their Council Tax Exemption Certificate from their educational institution.
In shared houses where some residents are students and some are not, the non-student residents are liable. The students are disregarded. If only one non-student lives there, that person qualifies for the single person discount.
Students living in university-managed halls of residence typically do not need to register personally - halls of residence are often Class M exempt and administered collectively by the university with the billing council.
Frequently Asked Questions
I moved into shared accommodation - am I liable for the full Council Tax bill?
If you are a joint tenant, you and your co-tenants are jointly and severally liable for the full bill. The council can pursue any one of you for the total. Between yourselves, you may agree to split the bill, but this arrangement does not bind the council. If one co-tenant does not pay their share, the council can pursue the others for the full amount.
My landlord says they will pay the Council Tax - do I still need to register?
You should still verify who is liable under the statutory hierarchy. If you are the resident tenant, you are the primarily liable person regardless of what your tenancy agreement says about the landlord paying. Some landlords do pay Council Tax as part of an all-inclusive rent arrangement, but if the landlord fails to pay, the council will pursue you as the liable person. Ensure any landlord-pays arrangement is covered by your tenancy agreement and consider independent confirmation that the council recognises the landlord arrangement.
How long does registration take to process?
Most councils process new registrations within 5 to 14 working days. During this period, you may not have access to the online portal or receive a formal bill. If you need a Council Tax bill urgently (for example, as proof of address), contact the revenues team to request an expedited letter confirming your registration.
I moved from one part of the country to another - do I need to contact both councils?
Yes. Contact the old billing council to close your account from your move-out date (and arrange any refund of overpaid amounts). Contact the new billing council to register from your move-in date. These are separate actions with separate councils and should both be done promptly.
What if I move into a property that already has someone else's Council Tax registered at the address?
If you are a new occupier and the previous resident has not notified the council of their move-out, the previous resident's name may still appear on the council's records. Register as a new occupier with your move-in date and the council will update the record. You are not liable for any Council Tax owed by the previous occupier.
How we verified this
The liable person hierarchy is sourced from the Local Government Finance Act 1992, section 6. Joint and several liability provisions are from the same Act.
