Student Exemptions (Class G)

Student exemptions are among the most commonly claimed, but the rules are specific and must be followed carefully to maintain exemption status.

Who Qualifies as a Student

For council tax purposes, students include:

Full-time university students on courses lasting at least one academic year
Further education students on full-time courses lasting 3+ months
Foreign language assistants and certain overseas students
Student nurses and those on healthcare professional courses
Apprentices aged under 20 or in their first year if older

Mixed Households

When students live with non-students:

Students are ‘disregarded’ for council tax purposes
Non-student residents remain liable for council tax
Single person discounts may apply if only one non-student lives there
Council tax reduction may be available based on the non-student’s income

Common Student Exemption Mistakes

Avoid these frequent errors:

Assuming part-time students qualify for exemption
Failing to notify councils when course status changes
Not claiming exemption for graduate accommodation during thesis writing
Missing exemptions for student accommodation occupied only during holidays

Empty Property Exemptions

Several exemptions apply to empty properties, but time limits and specific conditions must be met to maintain exemption status.

Class C – Standard Empty Property Exemption

Properties empty and substantially unfurnished qualify for exemption for up to 6 months. This exemption:

Starts from the day the property becomes empty and unfurnished
Continues for exactly 6 months regardless of ownership changes
Cannot be renewed or extended under normal circumstances
Applies to rental properties between tenancies

Class A – Major Works Exemption

Properties undergoing major structural works qualify for exemption while:

Substantial structural alterations are in progress
The property is uninhabitable due to the works
Work is proceeding with reasonable progress
Proper planning permissions and building regulations are followed

Time Limits and Renewals

Understanding time limits prevents unexpected liability:

Most empty property exemptions have strict time limits
Extensions require specific circumstances and council approval
Some councils charge premiums on long-term empty properties
Documentation proving empty status may be required

Disability-Related Exemptions

Several exemptions provide support for disabled residents and their carers, recognising the additional costs and space requirements of disability.

Severely Mentally Impaired Persons (Class N)

Properties occupied only by severely mentally impaired persons are exempt from council tax. This exemption requires:

Medical certification of severe mental impairment
Entitlement to qualifying benefits (typically severe disability premium)
All adult residents to qualify as severely mentally impaired
Regular review of medical and benefit status

Disabled Person’s Discount

While not technically an exemption, the disabled person’s discount provides similar relief by:

Applying where properties have been adapted for disabled residents
Covering additional rooms or space needed for disability reasons
Including ground-floor bathroom adaptations and wheelchair access

Armed Forces and Diplomatic Exemptions

Special exemptions support military personnel and diplomatic staff, recognising their unique accommodation circumstances.

Armed Forces Accommodation (Class O)

Service personnel living in designated military accommodation are exempt from council tax. This includes:

Barracks, married quarters, and other service accommodation
Accommodation provided directly by the Ministry of Defence
Temporary accommodation during posting or deployment
Family accommodation provided for service personnel

Diplomatic Exemptions (Class S)

Diplomatic staff and international organisation employees may qualify for exemption under specific circumstances related to their official status and accommodation arrangements.

Backdating and Refunds

Appeals and Disputes

If your exemption application is refused, comprehensive appeals processes protect your rights.

Internal Review

Start with your council’s internal review process:

Request written reasons for refusal decisions
Provide additional evidence supporting your claim
Ask for senior officer review of complex cases
Use formal complaints procedures where appropriate

Valuation Tribunal Appeals

Independent appeals to the Valuation Tribunal can:

Review evidence and make binding decisions
Order councils to grant exemptions
Award backdated refunds and compensation
Provide written reasons for their decisions

Maintaining Exemption Status

Once granted, exemptions require ongoing management to ensure continued eligibility.

Reporting Changes

You must notify councils when:

Property occupation status changes
Student status or course enrollment changes
Empty property becomes occupied or furnished
Major works are completed or abandoned
Medical conditions or benefit entitlements change

Regular Reviews

Councils may review exemptions periodically, requiring:

Updated evidence of continuing eligibility
Confirmation of unchanged circumstances
New applications when exemption periods expire
Appeals if reviews result in exemption withdrawal

Council tax exemptions provide valuable protection for specific circumstances, but they require careful application and ongoing management. Understanding the rules and maintaining proper documentation ensures you receive all exemptions you’re entitled to while avoiding unexpected liability.

If you believe you qualify for any exemption, contact your council immediately to start the application process. Professional advice from Citizens Advice or similar organisations can help with complex cases or disputes.
