Second Adult Rebate and Council Tax Disability Relief in Scotland

What the Second Adult Rebate Is

The Second Adult Rebate is a route within Scotland's Council Tax Reduction scheme under the Council Tax Reduction (Scotland) Regulations 2021 (SSI 2021/249). It can apply when a person liable for council tax lives with another resident whose income or benefit status meets the CTR rules, subject to the scheme's other conditions.

The assessment is based on the second adult's benefit status or gross income, rather than the liable person's income. For 2026/27 (from 1 April 2026), Schedule 2 sets a 25% rebate if the second adult receives a qualifying income-related benefit or State Pension Credit, or Universal Credit with no earned income. Based on gross income, after the specified benefit payments are disregarded, the rate is 15% below £282 a week and 7.5% from £282 to under £383 a week. A 100% rebate can apply in the special case where the dwelling would be wholly occupied by students but for second adult(s) receiving qualifying income-related benefits, State Pension Credit, or Universal Credit with no earned income. Other eligibility conditions apply.

This is distinct from the single person discount, which applies when only one chargeable adult lives in the property. SMI eligibility by itself does not determine whether a second-adult CTR route is available.

How It Interacts with Disability Disregards

Here's where it gets complicated. If the second adult in your household qualifies for an SMI disregard, they're removed from the headcount. If only one chargeable adult remains, the household qualifies for the 25% discount.

If both standard CTR and second-adult conditions are met, the council generally awards whichever calculation gives the greater reduction. The qualifying income-related benefit rules have a separate calculation.

If the second adult has a low income but doesn't qualify for an SMI disregard, ask the council whether the applicable CTR rules provide a second-adult route.

The Disabled Band Reduction Stacks

Regardless of whether you receive a second adult rebate or a single person discount through the SMI disregard, the disabled band reduction operates independently. If your property qualifies — because it has an additional bathroom, a room used predominantly by a disabled resident, or floor space for indoor wheelchair use — the band reduction is applied first, before any discount or rebate is calculated.

This means the second adult rebate (or single person discount) is calculated on the already-reduced band amount, compounding the savings.

Council Tax Reduction (CTR) as an Alternative

Scotland's means-tested Council Tax Reduction scheme is calculated against the remaining net liability. The council can confirm whether standard CTR or a second-adult assessment applies to the household.

You can receive CTR alongside an SMI disregard — CTR is calculated against the net bill after the disregard discount has been applied. Where both standard CTR and a second-adult rebate calculation are available, the council generally uses whichever is greater rather than adding the two calculations together.

Disability status alone does not establish a CTR award; the council assesses income and other circumstances under CTR rules.

Which Combination Works Best?

For most disability-affected households in Scotland, the optimal combination is:

1. Disabled band reduction (if the property qualifies) — applied first to reduce the baseline bill
2. SMI disregard (if applicable) — removes the impaired person from the headcount
3. Single person discount (if applicable), then CTR — CTR is calculated against the remaining liability

Apply for each relief that may fit your circumstances and provide the requested evidence. The council calculates each award under its own rules; a disability band reduction will not be included unless the council has assessed that entitlement.
