Council tax discounts you might already qualify for

Thousands of homes pay full council tax when they should not. Here is every discount, disregard and reduction worth asking for, and how to get it backdated.

Half the year is gone, but a discount awarded now usually cuts the instalments you have left.

If you live alone, share with students or carers, or your income has dropped, you are probably owed a council tax discount and nobody at the council will apply it for you. GOV.UK is blunt about this: "You need to apply for a Council Tax discount or an exemption, even if you're disregarded" — and once you ask, most councils will backdate it to the date you first qualified.

Half the billing year has gone. A discount awarded now is usually taken off the instalments you have left, so the monthly figure can drop sharply for the rest of the year.

Discount, reduction, exemption: what each word actually means

These four words get used interchangeably and they are not the same thing.

  • Discount — a percentage off the bill, usually 25% or 50%.
  • Disregard — a person the council does not count when working out how many adults live there. GOV.UK explains that a full bill assumes at least two adults live in the home, so removing one adult from the count creates a discount.
  • Exemption — no council tax at all on that property, for a set reason and often a set time.
  • Council Tax Reduction — a means-tested scheme run by your own council, based on your income and savings.

One more thing worth knowing: your council decides discounts and reductions, but your band is set by the Valuation Office Agency. Different bodies, different appeal routes. In Northern Ireland there is no council tax at all — households pay domestic rates, with separate schemes such as Rate Relief and Lone Pensioner Allowance through nidirect.

The single person discount, and who counts as living there

GOV.UK says you get 25% off if you pay the council tax and either you live on your own, or everyone else in your home is disregarded. That is the single person discount council tax rule in one line.

A few points that trip people up:

  • It applies to your only or main home, not a second home.
  • Someone working away or on a long holiday still counts as living there.
  • If a partner or housemate has moved out, Citizens Advice says you are entitled to the discount from the date they moved out, even if you told the council later.
  • If everyone in the property is disregarded, Citizens Advice says there is still a bill, but with a 50% discount.

Councils are required to review single person discounts and many use an outside contractor to write to households and check. Always reply to those letters. Knowingly giving false information is an offence under the Local Government Finance Act 1992 and can mean a fine.

The people who are disregarded, including carers and students

GOV.UK lists the adults who are not counted. They include someone under 18; some apprentices; anyone 18 or 19 in full-time education; full-time students at college or university; under-25s funded by the Education and Skills Funding Agency; student nurses; foreign language assistants registered with the British Council; people who are severely mentally impaired; a live-in carer looking after someone who is not their partner, spouse or child under 18; and diplomats.

Council lists go further and often add hospital patients and care home residents, people in prison, hostel residents, members of religious communities, a foreign student's spouse or dependant, and Homes for Ukraine guests.

Two situations worth checking carefully:

  • Carers. The live-in carer disregard is easy to miss, and at least one council has publicly admitted its own website left out some of the qualifying criteria. If you have cared for a relative in your home for years, ask about past years too.
  • Students sharing with workers. Citizens Advice warns that if students share with two or more employed non-students, those workers are likely liable for the whole bill, and the council can only chase them.

Some councils also give care leavers a full reduction up to their 25th birthday, but that is local discretion, not a national rule.

Council Tax Reduction: means-tested, and different in every council

Council Tax Reduction is help based on what you have coming in. Citizens Advice explains there are two rule sets: "working age" rules if you are under State Pension age, and "pension age" rules once you reach it, and the pension age rules are usually more generous.

Age UK points out that every council uses the same scheme for people over State Pension age, but the working-age scheme varies between councils. Some cap working-age support at 80% of the bill unless there are young children in the house.

Age UK also says that if you get the Guarantee Credit part of Pension Credit, your council tax may be paid in full.

The practical bit: many councils only start your reduction from the date they receive the application. So apply today rather than waiting until you have gathered every document — you can send evidence afterwards. Citizens Advice can also tell you whether Second Adult Rebate is a better claim in your case.

The severe mental impairment discount, and why backdating matters

This is the one that returns the largest sums. The severe mental impairment council tax discount comes from Schedule 1 of the Local Government Finance Act 1992, which requires "a severe impairment of intelligence and social functioning, however caused", and Citizens Advice explains that a claim for a qualifying benefit must also have been made.

It can cover people living with dementia, a stroke, a severe learning disability, Parkinson's or a serious brain injury. You will normally need a doctor to certify it plus proof of the qualifying benefit, on your council's own form. Some councils accept clear photos or screenshots of documents as long as everything is legible.

Citizens Advice advisers state that this discount can be backdated to the date the qualifying benefit was first claimed, with no time limit, even if that is many years earlier. Citizens Advice also notes that if everyone in the home is a student or is severely mentally impaired, there is no council tax to pay at all.

Empty homes, annexes and homes adapted for disability

  • Annexes. Citizens Advice says a 50% discount applies to an annexe used by people in the main property or their immediate family, there is no council tax on the annexe if a dependent relative lives there (which can mean aged 65 or over, or with a physical or mental disability), and an empty annexe is not charged.
  • Disabled band reduction. If a home has extra space needed because of someone's disability, the bill is charged one band lower — and for band A properties the reduction is one ninth of the bill. Scope stresses this is not a benefit and is not means-tested, so savings do not rule you out. You can get this and Council Tax Reduction.
  • Second and empty homes. The House of Commons Library explains that from 1 April 2025, councils in England can charge a premium of up to 100% on a second home — a furnished property with no resident — so double the normal bill. Long-term empty homes can attract far more, rising with the years empty. Wales and Scotland set their own premium rules. If your "empty" home is on the market or you have evidence it is not a second home, ask for the premium to be removed.

How to ask your council, and what to send

  1. Find your council through GOV.UK's council tax pages and use its own discount form where there is one.
  2. Say which discount, disregard or exemption you want, and the date you first qualified. Ask in writing for it to be applied from that date.
  3. Send evidence: student certificate, benefit award letter, tenancy end date, doctor's certification, or proof a property is being marketed.
  4. Keep a copy and note the date you asked.
  5. If you are refused, complain to the council first, then appeal to the Valuation Tribunal. The tribunal says the service is free and it cannot award costs, and a decision with reasons follows within a month of the hearing. Cumberland Council sets out the usual limit: appeal within two months of the council's decision, or two months from your appeal if the council does not decide. Appealing does not let you stop paying, but a win is refunded or credited.

Band challenges are separate — they go to the Valuation Office Agency's Listing Officer first, and you can start that from our council tax band check page.

Questions people ask

Can a council tax discount be backdated?

Usually yes, and Citizens Advice says a single person discount runs from the date the other adult moved out, even if you reported it late. The severe mental impairment discount can go back to the date the qualifying benefit was first claimed, with no time limit.

Does a lodger stop my single person discount?

Normally yes, because a second adult is living there, unless that person is disregarded — a full-time student, for example. Tell the council the facts and let them work out the count.

Is Council Tax Reduction the same everywhere in the UK?

No. Every council in England uses the same rules for people over State Pension age, but working-age schemes differ council by council, and Scotland and Wales run their own schemes; Northern Ireland has domestic rates instead.

I have savings. Can I still get help?

You may not qualify for means-tested Council Tax Reduction, but Scope points out the disabled band reduction is not means-tested, so savings do not disqualify you. Disregards for students and carers are not means-tested either.

If you are already behind, know your rights

Citizens Advice sets out the sequence: if you do not pay within seven days of a reminder, or it is your third late payment that year, the council sends a final notice demanding the rest of the year's council tax within seven days, then usually applies to court for a liability order.

Before that, Citizens Advice says the council should look at all other options first — including an affordable repayment plan or giving you time to apply for Council Tax Reduction. Ask for that in writing.

After a liability order, National Debtline says a council can only use one type of enforcement at a time for each order in your name, and a bailiff can only take goods belonging to the person named on the order — not goods belonging to other people or rented goods. Enforcement works differently in Scotland, where sheriff officers act on a summary warrant.

Prison is very rare and only where a court decides you deliberately did not pay and bailiffs could not recover the debt. Do not let fear stop you ringing the council. For free, independent help, contact Citizens Advice, National Debtline or StepChange — never a fee-charging firm.
