How to Get Council Tax Exemption When Disabled

Applies to: England, Scotland and Wales. Northern Ireland uses domestic rates instead of Council Tax.
Written by: Georgina, Founder of Purpl

You could reduce, discount or even remove your Council Tax bill if you are disabled, live with someone who is disabled, have a severe mental impairment, care for someone, or live on a low income.

Disability does not automatically give you full Council Tax exemption, but several schemes could lower your bill.

The main types of Council Tax help for disabled people include the Disabled Band Reduction Scheme, Severe Mental Impairment discount, Council Tax Reduction, carer discounts, disregards and local discretionary support. These schemes can feel confusing because councils use different words, including “discount”, “exemption”, “reduction”, “disregard” and “support”. The key is to check which route fits your household.

At Purpl, we know Council Tax can be one of the hardest bills to manage, especially when disability already brings extra costs such as heating, transport, mobility equipment, delivery fees, care, specialist food or adaptations. If your disability or long-term health condition affects how you use your home, who supports you, or what you can afford, it is worth checking whether your Council Tax bill can be reduced.

In summary

Council Tax exemption vs discount vs reduction

Before you apply, it helps to understand the wording.

A Council Tax exemption usually means the household does not need to pay Council Tax because of the property or household situation. For example, some homes can qualify for exemption if specific rules disregard everyone living there, such as the Severe Mental Impairment rules.

A Council Tax discount usually takes a percentage off your bill. This could reduce your bill by 25%, 50% or 100%, depending on who lives in the home and who the council counts for Council Tax purposes.

A Council Tax reduction usually lowers your bill because of your income, savings, benefits or household circumstances. Citizens Advice explains that people on a low income can apply for Council Tax Reduction, but working-age rules can vary because each local council runs its own scheme (https://www.citizensadvice.org.uk/housing/council-tax/check-if-you-can-pay-less-council-tax/).

The Disabled Band Reduction Scheme is different again. It does not usually remove your whole bill. It reduces the Council Tax charged on your home to the next lowest band if the property has extra space or facilities needed by a disabled person living there.

Purpl Tip: Do not only search for “Council Tax exemption”. You may miss help if your council calls it Council Tax Support, Disabled Band Reduction, disabled person’s reduction, Severe Mental Impairment discount, Significant Cognitive Impairment discount or a disregard.

Step 1: Check if you can get the Disabled Band Reduction

The Disabled Band Reduction Scheme can help if a disabled person lives in the property and the home has extra space or facilities because of their disability.

You may qualify if your home has:

an extra bathroom needed by the disabled person
an extra kitchen needed by the disabled person
another room needed by the disabled person, not just a normal bathroom, kitchen or toilet
enough extra indoor space for wheelchair use inside the home

If you qualify, your bill is reduced to the next lowest Council Tax band. For example, if your home is in Band D, you pay the Band C rate. If your home is already in Band A, GOV.UK says you can receive a 17% discount instead (https://www.gov.uk/council-tax/discounts-for-disabled-people).

The disabled person can be an adult or child, and they do not have to be the person responsible for paying the Council Tax bill. What matters is that the property has disability-related space or facilities that are needed because of their condition.

This can apply in situations such as:

a child needing a dedicated room for therapy, medical equipment or sensory regulation
a wheelchair user needing extra indoor space to move around safely
someone needing an extra bathroom because of continence, washing or care needs
someone needing a separate room for dialysis, medical equipment, treatment or disability-related support

In Wales, official guidance says the adaptation or extra space must be essential or of major importance to the disabled person’s wellbeing. It also confirms that outdoor adaptations alone do not qualify for this Council Tax reduction (https://www.gov.wales/council-tax-discounts-disregards-exemptions-and-reductions).

Purpl Insight: The Disabled Band Reduction Scheme is about how the home is used because of disability. Explain why the space or facility is needed, not just the name of the condition.

Step 2: Check if Severe Mental Impairment rules apply

Some people can get a Council Tax discount or exemption if they are classed as having a Severe Mental Impairment, often shortened to SMI. In Wales, the official wording may also refer to Significant Cognitive Impairment, or SCI.

This rule can apply where someone has a permanent impairment of intelligence and social functioning, and they meet the relevant benefit rules. MoneySavingExpert explains that SMI is a medical diagnosis in its own right and may apply to people affected by conditions such as dementia, Alzheimer’s, Parkinson’s, severe learning difficulties, multiple sclerosis, complications from cerebral palsy or strokes, depending on the person’s circumstances (https://www.moneysavingexpert.com/reclaim/severe-mental-impairment-dementia-council-tax-rebate/).

In Wales, a person can qualify for SCI-related Council Tax support if a doctor or medical practitioner certifies their condition and they receive at least one qualifying benefit. The Welsh Government lists qualifying benefits including Attendance Allowance, certain Disability Living Allowance rates, Personal Independence Payment, Armed Forces Independence Payment and Universal Credit in some limited capability for work cases (https://www.gov.wales/council-tax-discounts-disregards-exemptions-and-reductions).

The SMI discount depends on who else lives in the home:

100% discount may apply if the person with SMI lives alone.
50% discount may apply if the person with SMI lives only with people who are also disregarded.
25% discount may apply if the person with SMI lives with one counted adult.
No discount may apply if the person with SMI lives with two or more counted adults.

The exact outcome depends on who is counted, who is disregarded and who lives in the property.

Purpl Tip: If someone in your home has dementia, a severe learning disability, brain injury, Parkinson’s, stroke-related impairment or another condition affecting thinking and social functioning, check the SMI or SCI rules even if no one has ever mentioned them to you.

Step 3: Check if you can get Council Tax Reduction on a low income

Council Tax Reduction, sometimes called Council Tax Support, can reduce your bill if you are on a low income. This is separate from Disabled Band Reduction and SMI rules.

Your council may look at:

your income
your savings
your benefits
whether you have reached State Pension age
whether you live with a partner
whether other adults live with you
whether you receive Universal Credit, ESA, Income Support, JSA or Pension Credit
your local council’s rules

If you claim Universal Credit, do not assume Council Tax Reduction is included. You usually still need to apply separately through your local council. GOV.UK has a postcode checker that sends you to your local council’s Council Tax Reduction application page (https://www.gov.uk/apply-council-tax-reduction).

This matters because many people miss out simply because they think Universal Credit automatically includes help with Council Tax. It usually does not work that way.

Purpl Insight: Universal Credit does not automatically sort out your Council Tax bill. If you are on a low income, check Council Tax Reduction directly with your council.

Step 4: Check if anyone in your home should be disregarded

Council Tax usually assumes there are two adults in a property. If someone is “disregarded”, they are not counted as an adult for Council Tax purposes.

Someone may be disregarded if they are:

severely mentally impaired
a full-time student
a live-in carer in certain circumstances
under 18
in some training or apprenticeship situations
living permanently in hospital or a care home
part of another disregarded category

Carer rules can also matter. In Wales, carers may qualify for a Council Tax discount if they provide care for at least 35 hours a week, live in the same property as the person they care for, and care for someone receiving a qualifying benefit. The Welsh Government also explains that carers do not need to receive Carer’s Allowance for this discount, and their income and savings do not affect eligibility (https://www.gov.wales/council-tax-discounts-disregards-exemptions-and-reductions).

This is especially important for disabled households where there may be carers, adult children, students, or someone who has moved into residential care or hospital.

Purpl Tip: Look at your Council Tax bill and check how many adults the council is counting. If someone should be disregarded, your household may be paying too much.

Step 5: Gather the evidence before you apply

The evidence you need depends on which Council Tax scheme you are applying for.

For the Disabled Band Reduction Scheme, useful evidence may include:

proof that the disabled person lives in the property
medical evidence or a care plan
occupational therapy reports
social care documents
photos or descriptions of the extra room, bathroom, kitchen or wheelchair space
an explanation of how the space is used because of disability

For Severe Mental Impairment or Significant Cognitive Impairment, useful evidence may include:

a doctor’s certificate or medical practitioner confirmation
proof of a qualifying benefit
the date the person met the medical criteria
the date the person became entitled to the qualifying benefit
details of who else lives in the home

For Council Tax Reduction, useful evidence may include:

income details
savings and capital
benefit letters
rent or housing costs
household details
National Insurance numbers
bank statements or payslips

Date evidence is especially important for SMI or SCI claims because it can affect backdating. The Welsh Government previously confirmed that Wales introduced a standard SMI process with MoneySavingExpert and local authorities so eligible people could receive consistent support across Wales (https://www.gov.wales/wales-leads-the-way-in-helping-most-vulnerable-access-crucial-council-tax-discount).

Purpl Insight: The strongest applications usually explain the practical need, not just the diagnosis. “This room stores medical equipment and is used for daily therapy” is clearer than “we need a spare room because of disability.”

Step 6: Apply through your local council

You usually apply through your local council.

A simple step-by-step process is:

Search your council’s website for Council Tax discounts and exemptions.
Look for the right scheme, such as Disabled Band Reduction, Severe Mental Impairment discount, Significant Cognitive Impairment discount, Council Tax Reduction or discretionary reduction.
Complete the online form or request a paper form if the online form is not accessible.
Upload or send your evidence.
Ask for reasonable adjustments if you need support with communication, forms or phone calls.
Keep a copy of everything you send.
Ask whether the discount, exemption or reduction can be backdated.
Check your new bill carefully if your application is accepted.

If you live in Wales and apply for SMI or SCI, use the standardised application form. Every Welsh council backdates eligible claims.

If you cannot manage the application alone, ask for help from Citizens Advice, a welfare rights adviser, a carer organisation, Age UK, a disability charity, a housing association adviser or your council’s support team.

Purpl Tip: If the form is not accessible, ask your council for a reasonable adjustment. You can request a paper form, phone support, large print, email support, a named contact or extra time.

Step 7: Ask for backdating or challenge the decision if needed

Backdating matters because some people could claim back hundreds or even thousands of pounds.

For SMI backdating in England and Scotland, councils set their own policies and do not have to backdate claims in the same way. Some may not backdate, some may go back several years, and some may backdate to when the person started receiving a qualifying benefit.

For SMI or SCI backdating in Wales, the position is stronger. Wales uses a standardised SMI application form and every Welsh council backdates eligible claims. This means Welsh readers have stronger grounds to push back if their council refuses to backdate a valid claim.

If you are applying in Wales, include:

the date the person was medically certified or diagnosed as having SMI or SCI
proof of qualifying benefit entitlement
evidence showing when both the medical and benefit criteria were met
a clear written request for backdating under the Welsh standardised process

The key point is that both parts matter: the medical criteria and the qualifying benefit entitlement. If the council refuses to backdate or only backdates part of the claim, ask for the decision in writing and challenge it.

If your council refuses your SMI application, or accepts it but will not backdate it as far as you think it should, you can appeal. MoneySavingExpert explains that this applies where a claim is rejected or where you disagree with the backdating decision (https://www.moneysavingexpert.com/reclaim/severe-mental-impairment-dementia-council-tax-rebate/).

If you are struggling to pay your bill now, ask your council about Council Tax Reduction, discretionary reduction, affordable payment plans and any disability-related discounts you may have missed. Scope explains that Council Tax is a priority bill, and missed payments can lead to the council asking for the full year’s bill at once or taking court action (https://www.scope.org.uk/advice-and-support/help-with-council-tax-reduction-discount).

Purpl Insight: Backdating can be where the biggest refund sits, especially for SMI or SCI claims. Do not only ask for future discounts. Ask whether you are owed money from the date the person met both the medical and benefit rules.

What about Scotland and Northern Ireland?

Council Tax applies in England, Scotland and Wales, but local rules and application routes can vary.

In Scotland, Council Tax Reduction can reduce your bill depending on income, savings and household circumstances. SMI backdating can depend on your council’s policy, so ask your local council how far back they will consider a claim.

In Wales, the system is more consistent for SMI or SCI claims because the Welsh Government worked with MoneySavingExpert and local authorities to create a standard application process. The Welsh Government created this standard process so eligible people receive consistent support wherever they live in Wales.

Northern Ireland uses domestic rates instead of Council Tax. Disabled Persons Allowance offers the closest equivalent support and can reduce domestic rates by 25% when a property has adaptations that meet a disabled person’s needs (https://www.nidirect.gov.uk/articles/disabled-persons-allowance).

Purpl Tip: Use the right wording for where you live. In England, Scotland and Wales, search “Council Tax disabled reduction” or “SMI Council Tax discount”. In Northern Ireland, search “Disabled Persons Allowance rates”.

Frequently asked questions (FAQs) about Council Tax exemption when disabled

Can you get Council Tax exemption if you are disabled?

Not automatically. Being disabled does not usually remove your Council Tax bill by itself, but you may qualify for a discount, reduction or exemption depending on your circumstances. The main routes include Disabled Band Reduction, Severe Mental Impairment discount, Council Tax Reduction and carer-related disregards.

What is the Disabled Band Reduction Scheme?

The Disabled Band Reduction Scheme reduces your Council Tax bill to the next lowest band if your home has extra space or facilities needed by a disabled person. This could include an extra bathroom, extra kitchen, another room used because of disability, or enough indoor space for wheelchair use.

Who qualifies for Disabled Band Reduction?

You may qualify if a disabled person lives in the property and the home has an extra bathroom, extra kitchen, another room used because of disability, or enough indoor space for wheelchair use. The disabled person can be an adult or child, and they do not need to be the person named on the Council Tax bill.

Can I get Council Tax reduced if my child is disabled?

Yes, you may be able to apply for Disabled Band Reduction if your child is disabled and your home has extra space or facilities needed because of their disability. For example, this may include a room used for therapy, medical equipment, sensory regulation or care needs.

Can I get Council Tax exemption for autism, ADHD, dementia or a learning disability?

A diagnosis alone does not automatically give Council Tax exemption. However, some people may qualify under Severe Mental Impairment or Significant Cognitive Impairment rules if they have medical certification and meet the qualifying benefit rules.

What is Severe Mental Impairment Council Tax discount?

Severe Mental Impairment Council Tax discount applies when someone is medically certified as having SMI and meets the relevant benefit rules. People who qualify are disregarded for Council Tax, which can reduce or remove the bill depending on who else lives in the home.

Can Council Tax be reduced if I receive PIP?

Receiving PIP does not automatically remove your Council Tax bill. However, PIP may be a qualifying benefit for SMI or SCI in some cases, and it may support evidence for other disability-related Council Tax help. You may also qualify for Disabled Band Reduction or Council Tax Reduction depending on your home, income and household circumstances.

Is Council Tax Reduction the same as Disabled Band Reduction?

No. Council Tax Reduction is usually based on low income and household circumstances. Disabled Band Reduction is based on whether your home has extra space or facilities needed because someone living there is disabled.

Can SMI Council Tax discount be backdated?

Yes, but the rules differ depending on where you live. In England and Scotland, councils can set their own backdating policies. In Wales, the SMI process is standardised and every Welsh council backdates eligible claims.

What should Welsh readers do if the council refuses to backdate SMI or SCI discount?

Ask for the decision in writing and refer to the Welsh standardised process. Wales uses a standardised SMI application process and every Welsh council backdates eligible claims. You should include evidence showing when the person met both the medical criteria and the qualifying benefit rules.

Can Council Tax Reduction reduce my bill to zero?

It can in some cases, but it depends on where you live, your income, savings, benefits, age and household circumstances. You need to apply through your local council and check the local rules.

Can I get help if I am struggling to pay Council Tax arrears?

Yes. Contact your council quickly and ask about Council Tax Reduction, discretionary reduction, affordable payment plans and any discounts you may have missed. Council Tax is a priority bill, so it is better to act before arrears build up.

Can I appeal if my council refuses my Council Tax discount?

Yes. If your council refuses a discount or you disagree with how far an SMI claim has been backdated, ask for the decision in writing and check the appeals process.

What help exists in Northern Ireland if disabled people do not pay Council Tax?

Northern Ireland uses domestic rates instead of Council Tax. Disabled Person’s Allowance may reduce rates by 25% if the property has been adapted to meet the needs of a disabled person living there.

In summary

You could reduce your Council Tax bill if you are disabled, live with someone who is disabled, have a severe mental impairment, care for someone, or live on a low income.

Check the Disabled Band Reduction Scheme if your home has extra space or facilities because of disability. Check whether your council should disregard someone in your home if they have a Severe Mental Impairment or, in Wales, a Significant Cognitive Impairment. Apply for Council Tax Reduction through your local council if you are on a low income.

The biggest point to remember is backdating. In England and Scotland, SMI backdating depends on council policy. In Wales, every council backdates eligible SMI claims through the standardised process, which can give Welsh applicants stronger grounds to challenge if a council pushes back.

The most important step is to apply. Councils do not always add these discounts automatically, and many disabled people miss out simply because no one tells them they can ask.
