SMI Qualifying Benefits for Council Tax Exemption

The Qualifying Benefit Rule

Having a doctor certify severe mental impairment is only half of the eligibility test. The other half is benefit entitlement. Under Article 3 of The Council Tax (Discount Disregards) Order 1992 (S.I. 1992/548, as amended), the person must be entitled to at least one qualifying benefit on the day the disregard applies.

The word "entitled" matters. If a benefit payment is temporarily suspended — for example, because the person has been in hospital for more than 28 days — the underlying entitlement continues. The SMI disregard stays intact.

Full List of Qualifying Benefits (2026/27)

Attendance Allowance (AA) — either the lower rate (£76.70/week) or higher rate (£114.60/week). This is the most common qualifying benefit for older adults with dementia.

Personal Independence Payment (PIP) — Daily Living Component — standard rate (£76.70/week) or enhanced rate (£114.60/week). The mobility component alone does not qualify; the Daily Living Component specifically is required.

Disability Living Allowance (DLA) — Care Component — middle or highest rate. The lowest rate of the DLA care component does not satisfy the threshold. DLA is being phased out for working-age adults through managed migration to PIP, but existing awards remain qualifying benefits until they end.

Universal Credit with a Limited Capability for Work (LCW) or Limited Capability for Work and Work-Related Activity (LCWRA) element — the UC calculation must include an amount under Regulation 27(1) of the Universal Credit Regulations 2013 in respect of LCW or LCWRA, or would include such an amount but for Regulation 27(4) or 29(4). A basic UC award, a fit note, or a GP sickness declaration without the relevant determination is not sufficient.

Employment and Support Allowance (ESA) — main-phase ESA incorporating either the support component or the work-related activity component. Assessment-phase ESA does not qualify.

Severe Disablement Allowance (SDA) — under Section 68 of the Social Security Contributions and Benefits Act 1992. This legacy benefit has been closed to new claimants for years, but existing recipients qualify.

Incapacity Benefit — short-term at higher rate or long-term. Another legacy benefit largely replaced by ESA and UC.

Constant Attendance Allowance (CAA) — paid as an increase to a Disablement Pension or under military and civilian injury compensation schemes.

Armed Forces Independence Payment (AFIP) — under the Armed Forces and Reserve Forces Compensation Scheme Order 2011.

Unemployability Supplement/Allowance — under Part I of Schedule 7 to the SSCBA 1992 or War Pensions schemes.

Income Support with Disability Premium — where the applicable amount includes (or included) a disability premium or severe disability premium.

Common Stumbling Blocks

PIP Mobility-Only awards. Someone who receives PIP Mobility Component but was refused the Daily Living Component does not have a qualifying benefit for SMI purposes. If their cognitive impairment affects daily living tasks, a mandatory reconsideration or appeal of the PIP decision may add the Daily Living Component — and if successful, the award is typically backdated to the claim date.

Universal Credit without an LCW or LCWRA determination. A basic UC award or a fit note without a formal Work Capability Assessment determination is not sufficient. A person found to have LCW only can qualify; check whether the UC calculation includes the relevant LCW or LCWRA amount, or would include it but for the statutory exceptions. The UC statement (from the online journal) can help show the determination and applicable element.

Pending benefit applications. A person waiting for a PIP or Attendance Allowance decision does not yet have the qualifying benefit entitlement. The SMI claim can be submitted once the benefit is awarded. If the benefit award is backdated by the DWP, the council tax disregard can also be backdated to match the benefit start date.

Retrospective awards after appeal. If the DWP refuses a benefit and the person wins on appeal at the First-tier Tribunal, the award is usually backdated to the original claim date. This retrospective entitlement supports an SMI backdating claim to the same date.

Cross-Border Benefits

Adults who have moved to England from Scotland may hold Adult Disability Payment (ADP) or Pension Age Disability Payment (PADP) — Scotland's devolved equivalents of PIP and Attendance Allowance. English billing authorities generally accept these awards where they correspond to the equivalent English benefit, though the council tax rules applied are still those of the LGFA 1992.

What to Do Next

Check the DWP award letter for the person who may qualify. It shows the benefit name, the rate, and the start date. That start date — combined with the GP's certified onset date for the impairment — determines how far back the council tax discount can be applied. If no qualifying benefit is currently in place, applying for one is the first step before contacting the council about SMI.
