UK Council Tax Hub › Council Tax Exemptions Uk
Council tax has a long list of exemptions, discounts and disregards. Many households are entitled to reductions but do not claim them. This upgraded guide covers the most important categories: the 25 per cent single occupant discount, full exemptions for unoccupied or student-only properties, the severe mental impairment disregard, and the disabled band reduction. The claims process is set out clearly so households can identify what they are entitled to.
The 25 Per Cent Single Occupant Discount
Where only one adult lives in a property, the household gets a 25 per cent discount on the full council tax bill. The discount is not means-tested; it is purely based on the number of adults occupying the property.
Adult means a person aged 18 or over who is not disregarded for council tax purposes. Disregarded persons (students, severely mentally impaired people, etc.) are not counted as adults for the purpose of the discount. So a property occupied by one adult and one student gets the 25 per cent discount.
The discount is claimed through the council council tax service. Most councils have an online form. Once claimed, the discount continues until circumstances change. Households must report changes (another adult moving in, etc.) promptly to avoid overpayment recovery.
Full Exemptions - Unoccupied and Other Categories
Some properties are fully exempt from council tax under the Council Tax (Exempt Dwellings) Order 1992. The main exempt categories are: Class B (properties owned by a charity for a charitable purpose), Class C (unoccupied and unfurnished for up to 6 months in some councils), Class E (properties left empty by a person now in residential care or hospital).
Class F applies where the council taxpayer has died, exempting the property for up to 6 months from the date probate is granted. Class G applies to properties where occupation is prohibited by law. Class K applies to properties owned by a student where the student is the only person who would otherwise be liable.
Class N is the student exemption: properties occupied only by full-time students are exempt. A property occupied by students and one non-student adult is not exempt but qualifies for the 25 per cent single person discount because the students are disregarded.
Severe Mental Impairment Disregard
People who have a severe mental impairment can be disregarded for council tax purposes. The qualifying criteria are set out in the Council Tax (Discount Disregards) Order 1992. The person must have a permanent severe impairment of intellectual and social functioning, and must be entitled to certain qualifying benefits.
The disregard can result in a 25 per cent or 50 per cent discount on the council tax bill, depending on who else lives in the property. Where a severely mentally impaired person lives alone, they may be entitled to a full exemption rather than a discount.
Applications need a doctor confirmation that the criteria are met. The council provides a form for the doctor to complete. The disregard is significantly under-claimed; Alzheimer Society and similar charities campaign for greater awareness of the entitlement.
Disabled Band Reduction
Where a property has been adapted to meet the needs of a disabled occupant, the household may qualify for a reduction in the council tax band. The reduction moves the band down by one (so a Band D property pays at Band C rates).
Qualifying adaptations include an additional bathroom, an additional kitchen, an extra room used to meet the disabled occupant needs, or sufficient floor space to allow use of a wheelchair indoors.
Band A properties cannot move down a band, so they receive a notional reduction based on the lower of the Band A rate or a 1/9 reduction. The reduction applies as long as the property remains adapted and the disabled person remains in occupation.
Council Tax Reduction (Support Scheme)
In addition to the discounts and disregards, low income households can apply for Council Tax Reduction (also called Council Tax Support). This is a means-tested scheme administered by each council. It can reduce the council tax bill by up to 100 per cent for pension-age households on Pension Credit.
Working-age Council Tax Reduction is set by each council under powers in the Local Government Finance Act 2012. Schemes vary significantly by council. Most cap support at 75 to 85 per cent of the council tax bill for working-age households, with no support at all in a few councils.
Applications are made to the council. The form asks for income, savings and household details. Universal Credit recipients are often passported through to Council Tax Reduction with minimal additional information.
Less Well-Known Exemptions Worth Checking
Empty property between owners. A property that is unoccupied and unfurnished between owners can be exempt for a short period under Class C. The exemption length varies by council; many limit it to between two weeks and six months.
Annexes. A self-contained annexe occupied by a dependent relative can be exempt from council tax under Class W. The relative must be elderly, severely disabled, or dependent in another defined way. The exemption applies to the annexe only, not the main property.
Properties of armed forces personnel. Forces personnel stationed away from home may be entitled to specific reductions. Each council scheme treats this differently. The Armed Forces Covenant requires councils to ensure forces personnel are not disadvantaged.
Granny annexes occupied by a family member. Under Class T, a granny annexe occupied by a family member receives a 50 per cent reduction. The classes are technical but together they provide significant relief for many family living arrangements.
Where to Get Free Independent Help
Citizens Advice provides free guidance on council tax exemption, including council tax discounts, exemptions, support schemes and band challenges. Local Citizens Advice offices can also help with form-filling, evidence-gathering and challenges to council decisions where needed.
The council own council tax service is the entry point for most issues. Most councils have an online portal where customers can manage their account, claim discounts, report changes and pay bills. The council customer service team handles enquiries that cannot be resolved online.
The Valuation Office Agency (VOA) sets council tax bands and handles band challenges. The gov.uk Check your council tax band and Challenge your council tax band services are the official routes. The VOA Council Tax service is free to use.
The Valuation Tribunal for England handles appeals against VOA decisions on council tax bands and against council decisions on Council Tax Reduction. The tribunal is free, accessible to litigants in person, and decides by reference to the same evidence as the VOA and council.
For Wales, the Valuation Tribunal for Wales handles equivalent appeals. The Welsh Government council tax pages explain the Welsh system, which has nine bands based on 2003 values. The Welsh Government is consulting on a further revaluation that would update the bands to a more recent reference date.
For council tax debt, StepChange and National Debtline provide free debt advice that includes council tax arrears. Council tax debt is collected by the council through court summons and bailiff enforcement, but the council also has a duty to offer affordable repayment arrangements before resorting to enforcement.
Putting It All Together
The rules above set out the legal framework, the practical steps and the support routes available. Where the situation is straightforward, the gov.uk pages and the official tools should be enough to act on. Where the situation is more complex, the free advice services listed in the previous section can usually clarify the position and identify the right next step. Many issues that look intractable at first turn out to be resolvable once the right service is engaged.
Keeping written records of communications and decisions throughout is good practice. Where a decision needs to be challenged later - through an internal complaint, an ombudsman, a tribunal or a court - the quality of the contemporaneous record often decides the outcome. Dates, names, reference numbers and copies of correspondence are the building blocks of any later dispute. The gov.uk advice pages and the relevant ombudsman or tribunal websites all set out the evidence they consider when reviewing decisions, and gathering that evidence from the start is one of the most effective protections available.
Frequently Asked Questions
Can I get a discount if I live alone?
Yes. A 25 per cent discount applies where only one adult lives in the property. The discount is not means-tested. It must be claimed through the council council tax service.
Are students exempt from council tax?
Properties occupied only by students are exempt. Properties with students and one non-student adult pay the council tax with a 25 per cent discount because the students are disregarded.
What is the severe mental impairment discount?
A disregard for council tax purposes for people with permanent severe intellectual or social functioning impairment, entitled to certain qualifying benefits. It can result in a 25 to 100 per cent discount.
Can my band be reduced if I am disabled?
Possibly. Where a property has been adapted to meet the needs of a disabled occupant - extra bathroom, additional space for wheelchair use - the band is reduced by one band.
How do I apply for these discounts?
Through the council council tax service. Most councils have online application forms. Supporting evidence such as student certificates, doctor letters or photos of adaptations may be required.
Will the discount be backdated?
Most discounts are backdated to the date the qualifying circumstances arose, provided the council is told within a reasonable time. Long delays may limit backdating.
Can I get a discount and an exemption at the same time?
Some exemptions and discounts can be combined; others cannot. The council assesses the household and applies the most beneficial combination of discounts and exemptions allowable under the local scheme.
What is a Class T exemption?
A 50 per cent reduction for granny annexes occupied by a family member of the main property occupant. The annexe must be self-contained but used as part of the family living arrangements.
Are discount and disregards backdated?
Yes, most are backdated to the date the qualifying circumstances arose. Long delays in reporting can limit backdating. The council scheme document sets out specific backdating rules.
Can I get a single person discount if I share with a lodger?
It depends. If the lodger is a separate adult occupier, the discount does not apply. Specific tests look at whether the lodger pays for a separate self-contained part of the property.
