The Severe Mental Impairment (SMI) Statutory Exemption
Under Paragraph 2 of Schedule 1 to the Local Government Finance Act 1992, a person is legally disregarded for Council Tax if they have a severe mental impairment. This provision is vital for families coping with Alzheimer's, dementia, and severe brain conditions.
The Two Criteria You Must Fulfill
- Doctor's Certification: A signed statement from a GP or consultant confirming that the individual has a permanent impairment of intelligence and social functioning.
- Qualifying Disability Benefit: The individual must be entitled to (or receiving) one of the following benefits:
- Attendance Allowance
- Personal Independence Payment (PIP) Daily Living Component
- Disability Living Allowance (DLA) Higher or Middle Care Component
- Employment and Support Allowance (ESA)
Discount Levels According to Household Composition
- Person with SMI lives alone: 100% exemption (Class U) • Zero Council Tax payable.
- Person with SMI lives with 1 adult: 25% Single Person Discount applied.
- Person with SMI lives with a live-in non-spouse carer: Both are disregarded • 50% discount applied.
Claiming Backdated Rebates
Because many families are never informed of this exemption at diagnosis, millions in overpaid Council Tax go unclaimed. Write to your council's revenues service with the doctor's certificate and benefit entitlement letter, requesting a full retrospective refund.

Frequently Asked Questions
What conditions qualify for Severe Mental Impairment (SMI)?
Common qualifying conditions include advanced dementia (Alzheimer's), severe Parkinson's disease, severe strokes, significant learning difficulties, or profound brain injuries. The condition must involve a permanent, severe impairment of intelligence and social functioning.
What are the two mandatory criteria for the SMI disregard?
1) A medical certificate signed by a registered medical practitioner (such as your GP) confirming severe mental impairment; and 2) Entitlement to at least one qualifying disability benefit (such as Attendance Allowance, PIP daily living component at standard/enhanced rate, or Disability Living Allowance higher/middle rate care).
Can an SMI discount be backdated?
Yes! If your family member was diagnosed with dementia and was entitled to Attendance Allowance for several years without claiming the Council Tax disregard, councils can backdate the refund to the exact date the qualifying benefit began. Families frequently receive refunds of £2,000 to £8,000.
Can a spouse qualify for the Live-In Carer disregard?
No. Under statutory carer disregard rules, you cannot claim the carer disregard if you are caring for your spouse, civil partner, or a child under 18. However, you CAN claim the carer disregard if caring for an elderly parent, sibling, or adult child.
