Council Tax Scotland: Who Is Liable and How Joint Liability Works

The Liability Hierarchy

Section 75 of the Local Government Finance Act 1992 sets out a strict hierarchy to determine who pays council tax on a Scottish property. The council works down the list and stops at the first person who fits:

1. Resident owner-occupier — someone who owns or holds a liferent in the property and lives there
2. Resident tenant — someone who holds a lease, tenancy, or statutory tenancy and lives there
3. Resident sub-tenant or lodger — someone with a lawful sub-lease or licence to occupy
4. Ordinary resident — someone living in the property as their sole or main residence without a property interest
5. Non-resident owner — the owner when no one lives in the property at all

This hierarchy matters because it determines who the council can chase for payment. If you own the property and live in it, you're liable at step 1 regardless of who else lives there. If you're a tenant and the landlord doesn't live in the property, you're liable at step 2.

Joint and Several Liability

When two or more people occupy the same tier in the hierarchy — say, joint tenants whose names are both on the lease — they're jointly and severally liable for the full bill. That means the council can pursue either person for 100% of the debt, not just their "share." If your flatmate doesn't pay their half, the council can come to you for the lot.

Crucially, spouses, civil partners, and couples living together as if married are automatically jointly and severally liable under Section 75(3), even if only one name appears on the tenancy agreement or title deed. The council doesn't need to prove who earns what or who agreed to pay — both partners are liable by default.

Owner-Liable Properties (HMOs)

In most shared houses, tenants are individually liable. But if a property qualifies as a House in Multiple Occupation for council tax purposes — meaning the residents don't form a single household and each has a separate tenancy or pays individual rent — liability shifts to the property owner.

The council tax definition of an HMO is broader than the licensing definition under the Housing (Scotland) Act 2006. A property can be owner-liable for council tax even if it doesn't need an HMO licence. If you're a tenant in an owner-liable property, the landlord pays the council tax — though they may build the cost into your rent.

What "Sole or Main Residence" Means

The phrase "sole or main residence" determines whether someone counts as a resident at a particular address. It's a factual question — where is the centre of your personal, domestic, and civic life? A tenancy agreement or property ownership may be relevant evidence, but neither proves by itself that the property is your sole or main residence.

If you're an offshore worker who spends months on a platform but your family stays at the house, the house is still your main residence. If you've separated from a partner and moved out, the property stops being your main residence when you establish a new one elsewhere.

This matters for discounts: the 25% single person discount requires only one counted adult whose sole or main residence is the property. Everyone else who lives there must be disregarded (students, care leavers, carers) or not count as residents.

When You're Not Liable

You're not liable for council tax on a property if you don't live there and don't own it. Guests and visitors don't become liable — though if a stay extends beyond several months without a permanent residence maintained elsewhere, the council may treat the guest as a resident.

Children under 18 are never liable for council tax and are automatically disregarded when counting adults in the household.
