Council tax discounts - persons with severe mental impairment

Anyone who is medically certified as being Severely Mentally Impaired (SMI) may be eligible for a Council Tax exemption or discount. This means that the person will have a severe impairment of their intellectual and social functioning that appears to be permanent.

Conditions that can lead to severe mental impairment (SMI) include:

  • Alzheimer’s disease and other forms of dementia
  • Parkinson’s disease
  • Severe learning difficulties, or
  • A stroke

Many other conditions may apply.

To be eligible, the person must be diagnosed as SMI by a doctor and must also be entitled to a qualifying benefit.

How much discount can you get?

Your full council tax bill is based on at least two adults (people over 18) living in a property.

People certified as Severely Mentally Impaired do not count towards the number of adults considered to be living in a property.

This means if 2 adults live in a property and 1 of them is a person with severe mental impairment, the bill will be worked out as if only 1 adult lives there. This would reduce the bill by 25%.

If the only person or all persons living in the property have severe mental impairment, they will be fully exempt from council tax.
