Council Tax for HMO Properties 2026/27
Who pays council tax on an HMO
Since December 2023, an HMO as defined under section 254 of the Housing Act 2004 is treated as a single dwelling for council tax purposes — one property, one band, one bill. Crucially, that bill falls on the owner or landlord, not the individual tenants, whenever the property is let room-by-room rather than as a whole unit on a single tenancy. This reversed years of inconsistent local billing where some councils charged tenants directly for their room.
The distinction that matters is how the tenancy is structured. If you let an entire property to one household on a single assured shorthold tenancy, the tenant is liable for council tax for the duration of that tenancy — including through their notice period, following the Renters’ Rights Act changes that took effect from 1 May 2026. The landlord only becomes liable again once the tenancy has formally ended. But where a property is let by the room to multiple unrelated tenants (the standard HMO arrangement), the landlord remains liable throughout.
How this affects your numbers as a landlord
- Most HMO landlords build the council tax cost into the room rent, since tenants aren’t billed separately
- Converting a property into an HMO can push it into a higher council tax band, so the total annual bill needs re-checking after conversion, not assumed to stay the same as before
- Because you’re paying council tax as a landlord expense rather than passing it through, it’s a genuine deductible cost against your rental income when calculating tax
- Empty HMO rooms between tenants don’t reduce your liability — the bill is for the whole dwelling, occupied or not
Checking your actual banding
Council tax bands vary significantly by local authority and by how a property was assessed before and after HMO conversion. The fastest way to confirm your current band, rather than guess from a neighbouring property, is to look it up directly.
