Why it matters
What Council Tax means for a landlord
Council tax is a running cost that landlords often forget to budget for. While the property is let, the tenant usually pays. But the bill falls back on you during every void, so a slow re-let costs lost rent plus council tax. Since 1 December 2023, most HMOs count as a single dwelling. That means the landlord pays for the whole house, not the individual tenants. Many councils also add an empty-homes premium of up to 100% once a property has been empty for a year. Longer voids cost even more, so a slow refurbishment can carry a real tax penalty.
Worked example
How it plays out
Priya lets a 2-bed flat in council tax Band C (about £1,750 a year). Her tenant moves out on 1 March and the flat sits empty for a six-week refurbishment. From the day the tenancy ends, the liability switches back to Priya, so she pays roughly £200 of Band C council tax on top of the lost rent for that void. She also runs a 4-bed HMO let room by room: since 1 December 2023 it is banded as a single dwelling, so Priya, not her five tenants, pays its £2,100 annual bill. If the flat stayed empty beyond 12 months, the council could add an empty-homes premium and roughly double the charge.
Common mistakes
Where landlords go wrong
- 01Assuming the tenant is always liable: during any void the landlord pays from the day the tenancy ends.
- 02Forgetting that since 1 December 2023 most HMOs are billed as one dwelling, so the landlord pays, not the individual tenants.
- 03Not telling the council the exact move-in and move-out dates, which causes mis-billed periods and chase letters.
- 04Overlooking the empty-homes premium: a property empty over 12 months can attract up to 100% extra, and more for longer voids.
What to do
A short checklist
- Tell the council the exact tenancy start and end dates for every let.
- Budget council tax into your void costs, not just the lost rent.
- Check whether each HMO is billed as a single dwelling and confirm who the council holds liable.
- For any long-term empty property, ask the council about the empty-homes premium and any exemptions before work starts.
