Council Tax Reduction calculator.
Council Tax Reduction (CTR) is a discount on your council tax, set by each local authority using their own scheme. Our calculator gives you an indicative figure to know what to aim for — for the exact amount, you have to apply through your council.

Why "council tax reduction" varies by council
In 2013, the government scrapped the old national Council Tax Benefit and gave each English local authority the power to design its own scheme. The result is 300+ different schemes, with very different generosity levels:
- Some councils still offer a maximum 100% reduction for the poorest households.
- Some require a minimum contribution from working-age claimants — 10%, 20%, or even more.
- Scotland and Wales kept national schemes, which are more generous and consistent.
- Pensioners are protected by a national scheme that mirrors the old Council Tax Benefit rules — pensioner CTR is therefore much more consistent across the UK.
Our calculator estimates a generic figure based on income and household. To get the real number, find your council on gov.uk/find-local-council and apply for "Council Tax Support" (some councils call it CTS rather than CTR).
Other council tax discounts to check
CTR isn't the only way to lower your council tax bill. Most people miss at least one of these:
- Single Person Discount (25%): If you live alone, or are the only adult living with under-18s.
- Disabled Band Reduction: If your home has been adapted for a disabled person, your bill drops to the band below your property's actual band.
- Severe Mental Impairment: If you (or someone you live with) is medically certified as severely mentally impaired and receives a qualifying benefit (e.g. PIP daily living), they are "disregarded" — and if everyone else in the household is also disregarded, the bill drops by 50% or to zero.
- Student exemptions: A property occupied only by full-time students pays no council tax.
- Carer Discount: Live-in carers (not for a partner or a child under 18) can be disregarded.
- Hardship: Councils can write off bills in cases of severe hardship — under Section 13A of the Local Government Finance Act 1992. Rarely advertised; always worth asking.
How to apply
Apply directly to your council. You'll usually need:
- Your council tax account number (on any recent bill).
- Proof of identity for everyone in the household.
- Proof of income — payslips, UC statement, pension statements.
- Proof of savings — bank statements covering the last 2 months.
- Tenancy or ownership details.
You can usually apply the same time as you apply for Universal Credit — and CTR can be backdated up to 6 months if you can show "good cause" for the delay (3 months for working-age claims in some councils).
Frequently asked questions.
How is Council Tax Reduction calculated?
Each local authority designs its own scheme for working-age claimants, so the exact maths varies. Most schemes compare your income to a notional "applicable amount" and reduce your council tax by a percentage of the gap — capped, sometimes, at less than 100%.
Can I get CTR and UC at the same time?
Yes. CTR is a separate scheme run by your council, not by DWP. You apply for them separately, but receiving UC often qualifies you automatically for CTR — your council will use the UC data with your permission.
Will CTR cover my whole council tax bill?
Sometimes. Pensioners on Guarantee Pension Credit usually get 100% reduction. Working-age claimants on a maximum award depend on their local scheme — in some councils they pay nothing, in others they have to pay at least 20%.
What if I miss the application deadline?
CTR can usually be backdated up to 3 months automatically — and longer if you can show good cause (illness, bereavement, given wrong advice). Apply as soon as you can and explain the delay in your application.
Are pensioners treated differently?
Yes. Pensioner CTR is governed by a national set of rules that closely mirrors the old Council Tax Benefit. It's much more generous than most working-age local schemes, and broadly the same wherever you live in the UK.
