Council Tax
Council Tax is collected by local councils to pay for local services.
If you let a whole flat or house on an ordinary tenancy, the tenant will usually be the one who pays. The main exceptions tend to be empty properties and room-by-room lets. That matters because councils do not bill whoever feels most responsible. They bill whoever falls highest in the legal order.
It is also worth telling the council as soon as a tenancy starts, ends, or a property becomes empty. Most billing decisions are made based on the occupation details already in the council’s system.
Who pays Council Tax?
Liability is determined using the statutory hierarchy set out in section 6 of the Local Government Finance Act 1992.
The council checks each level in turn. The first person who qualifies is liable. Someone living in the property as their home will usually take precedence over the owner. The owner becomes most important when nobody lives there.
If two or more people fall within the same level, for example, joint tenants, they are normally jointly and severally liable.
Key terms
Resident
A resident is a person aged 18 or over who lives in the dwelling as their sole or main residence.
So if your tenant actually lives there as their main home, they will usually be liable.
Owner
For Council Tax, “owner” does not just mean the freeholder.
It means the person who has the relevant material interest in the property, provided nobody else has a lower material interest.
Owner liability usually comes up in two situations:
- the property is empty, so there is no resident
- the property falls into a category where the owner is liable even though someone is living there, which can happen with some HMOs
Material interest
Material interest is the concept that links liability to the kind of tenancy involved.
From 1 May 2026, it includes:
- a freehold interest
- a leasehold interest granted for at least six months
- a tenancy that is, or was, an assured tenancy under the Housing Act 1988
That last change is the one most landlords are likely to notice.
The change from 1 May 2026
From 1 May 2026, fixed terms are banned for assured tenancies. The default position is an assured periodic tenancy.
Before then, material interest often depended on whether the tenancy had been granted for at least six months. That created a problem with weekly and monthly periodic tenancies. Even if they followed a longer fixed term as a statutory periodic tenancy, they could still fail the test. If the property was empty, councils sometimes used that to shift liability back to the landlord.
From 1 May 2026, that gap should disappear. An assured tenancy, including an assured periodic tenancy, counts as a material interest even if the rent is paid weekly or monthly.
What this means in practice
If an assured tenancy is still running but nobody is actually living there, the tenant will usually still have the relevant material interest for Council Tax purposes. A common example is where the tenant has moved out, but the tenancy has not legally ended.
Liability should only move back down the hierarchy once the tenancy has really ended. For example:
- the tenant’s notice has expired
- the landlord has accepted a surrender
- possession has been recovered, and the tenancy is over
The awkward cases are the ones where the tenant leaves early. Taking back keys, re-letting, or doing something else that shows you accepted the tenancy had ended may amount to accepting a surrender, whether you meant to or not.
Empty properties and unoccupied periods
An empty property still has to sit somewhere in the hierarchy. In practice, that usually turns into a dispute about who counts as the owner.
Discounts and premiums for empty homes vary from one council to another. The points that tend to catch landlords are these:
- a council may give a discount for an empty home, but it does not have to
- an empty homes premium can be charged once the property has been empty for long enough, and the amount can rise the longer it stays empty
- some second homes can also attract a premium if they are furnished, but nobody lives there as their main home
- if the property is genuinely uninhabitable and needs major works, you may be able to apply for a discount, an exemption, or, in some cases, removal from the Council Tax list, but that depends on the facts and the council’s own process
If there is an argument about liability, expect the council to rely heavily on its own records. You may need to produce tenancy dates, the date the occupier left, and proof that the tenancy was still running if that is your case.
When the tenant has moved out but the tenancy has not ended
This is where many Council Tax disputes start.
Usually, the tenant has left without proper notice or has simply abandoned the property, but the landlord cannot simply declare the tenancy over without following the proper legal process.
From 1 May 2026, where the tenancy is an assured periodic tenancy, the tenant should still be counted as having a material interest, even if the tenancy runs week to week or month to month. That makes it harder for a council to say the landlord has become liable just because the tenancy is periodic.
For non-assured tenancies, though, the six-month rule can still be decisive.
Non-assured tenancies
The wider definition of material interest, effective from 1 May 2026, only applies to assured tenancies.
With other arrangements, the old question may still matter: was the tenancy granted for at least six months?
That can still come up with:
- common law tenancies that are not assured
- company lets
- licences and other non-assured arrangements, depending on the facts
This is where the detail of the tenancy starts to matter. A statutory periodic tenancy that arises after a fixed term often counts as a new tenancy for the length of each period. A contractual periodic tenancy that continues under the original agreement may be treated as a single continuing tenancy. It depends on the wording and the facts.
That distinction has mattered because a new weekly or monthly periodic tenancy usually does not count as one granted for six months or more, even if it follows a longer fixed term.
Council Tax in HMOs
Billing and banding
In England, from 1 December 2023, most HMOs should be treated as a single dwelling for Council Tax purposes. That is still the case even if individual rooms or bedsits have features that once made them look self-contained, such as an en suite or a small kitchenette.
The point of the change was to prevent a single HMO from being split into several internal units, each with its own band and Council Tax bill.
Section 257 HMOs are excluded.
Liability in HMOs
Even when an HMO is billed as a single dwelling, some shared houses still fall into owner-liable categories under the Council Tax (Liability for Owners) rules, including Class C.
Class C broadly covers properties that:
- were built or later adapted for occupation by people who do not form a single household
- are occupied by people who rent or occupy only part of the dwelling rather than the whole
- count as HMOs for the purpose of these rules
The word “adapted” matters, but it is not the whole story. The question that usually decides liability is much simpler:
Does anyone hold a tenancy or lease of the whole dwelling?
- If the whole property is let on one tenancy, such as a joint tenancy for sharers or a family tenancy, the tenant or tenants will usually be liable.
- If separate occupiers rent separate rooms, nobody has the whole dwelling, so the owner will usually be liable.
- If the whole house is let to a company and the company then sublets rooms, the company will usually be liable because it holds the tenancy of the whole dwelling.
So yes, a house can be physically set up for multiple occupiers, for example, with locks on bedroom doors, and the tenants can still be liable if the legal letting is of the whole property on one tenancy.
A common trap
Watch the wording of the tenancy agreement. If parts of the property are carved out for the landlord’s use, such as a loft, garage, locked basement, storage room, or even a cupboard, some councils will argue that the tenant does not have the whole dwelling. That can push liability back onto the owner, even though everyone thought it was a whole-house let.
Student households
A property can be exempt if it is occupied entirely by full-time students.
In practice:
- the students usually need to apply and provide proof from their college or university
- if the tenancy runs through the summer, the exemption can often continue during the vacation, but the paperwork still needs to be done properly
If you are the person being billed, you may need the students’ evidence to support the exemption.
Discounts, disregards and the single person discount
Council Tax usually assumes at least two adults live in a property.
If only one adult counts, a 25% single-person discount usually applies.
Some people are not eligible for discounts, including many full-time students. If everybody in the property is disregarded, the bill may fall sharply, and in some cases, there may be an exemption, but you still normally have to apply for it.
What landlords should do
Tell the council quickly
When something changes, tell the council straight away. That includes:
- tenancy start and end dates
- the tenants’ full names
- a forwarding address, if you have one
- the date the property became empty, if it is empty
Keep evidence
If liability is disputed, especially where the tenant has gone, but you say the tenancy is still running, keep hold of:
- the tenancy agreement
- copies of notices served or received
- evidence that you did not accept a surrender, if that point matters
- rent records and correspondence showing the tenancy was treated as continuing
- evidence that the dwelling was still occupied, such as the tenant’s furniture
If the bill is wrong
Councils do get this wrong, particularly when the tenant has left, but the tenancy has not ended.
Challenge the bill quickly. Use the council’s review process first and, if necessary, appeal to the Valuation Tribunal.
