SMI is defined as, ‘A severe impairment of intelligence and social functioning which appears to be permanent’. This means that while people with dementia are likely to qualify for the discount, it depends on how significantly it affects them.
It also depends on who the person with dementia lives with. They will qualify for a 100% discount on Council Tax – in other words, they will pay nothing – if any other adult they live with is:
- also ‘severely mentally impaired’
- a full-time student at college or university
If any other adults who the person lives with is also defined as SMI (eg if they also have dementia) or are in the ‘disregarded’ category, they will qualify for a 50% Council Tax discount. People who are ‘disregarded’ include those who are:
- under 18
- 18 or 19 and in full-time education
- on certain apprentice schemes
- a full-time student at college or university
- under 25 and receiving funding from the Education and Skills Funding Agency
- a student nurse
- a foreign language assistant registered with the British Council
- the person’s live-in carer (unless the carer is their spouse, partner or child under 18)
- a diplomat
If you live with someone with dementia who qualifies for a Council Tax discount, you will receive a 25% discount if:
- there are no other adults in the household, or
- everyone else you live with is ‘disregarded’
To prove that the person’s dementia has a significant effect on how they function, they will need a letter from their doctor. They will also need to prove to their local council that the receive certain other benefits – this varies between areas, and you will need to contact your council to find out which benefits count.
