When working out how many people live in a property, some people are not counted. These are called disregarded people. If everyone who lives in the property is disregarded, there will still be a Council Tax bill but there will be a 50% discount. The exception is when all the occupants are disregarded students then there will be 100% discount. More information is available on people who are disregarded.
If only one person who counts for council tax lives in a property they qualify for a 25% discount on their Council Tax bill. You should receive this discount automatically when you register for Council Tax. If you are the only person living in a property and are not receiving this discount then you should contact your local council.
Armed Forces personnel serving overseas also receive a discount on their Council Tax bill. The discount for service personnel deployed on specified operations overseas is 50%.
Those diagnosed as "severely mentally impaired" don't have to pay Council Tax (choose 'no CT liability' under the council tax band question). Two-person households, where one is a sufferer, qualify for a 25% discount. A person is severely mentally impaired if they have a severe impairment of intelligence and social functioning which appears to be permanent, such as dementia.
To claim for a severely mentally impaired or SMI discount, the person must have been certified as having a severe mental impairment by a doctor, and be eligible for, but not necessarily receiving, at least one disability benefit such as Attendance Allowance, Personal Independence Payment or Disability Living Allowance.
