Council Tax Reduction Taper Rate and Applicable Amount Explained

Two Types of Calculation

English councils use two main methods to work out how much Council Tax Reduction you receive. Traditional means-tested schemes compare your income against an "applicable amount" and taper the award down as income rises. Income-banded schemes place your household income into a bracket and assign a flat percentage discount. Your council's adopted scheme document determines which method applies to you.

The Means-Tested Method

In a means-tested scheme, the applicable amount is your household's weekly living allowance under the scheme rules. It is built from personal allowances (a fixed amount for a single person or couple), child allowances, and premiums for disability, caring responsibilities, or severe disability. Think of it as the council's measure of what your household needs to live on.

If your net weekly income is at or below the applicable amount, you receive the maximum CTR award — which may be 100% of your council tax liability, or a lower cap such as 80% or 85%, depending on the scheme.

If your income exceeds the applicable amount, the excess is multiplied by the taper rate — typically 20%. The result is subtracted from the maximum award. For example, if your excess income is £50 per week and the taper is 20%, your award drops by £10 per week.

The full formula:

Weekly CTR = Maximum Award − (Excess Income × Taper Rate) − Non-Dependant Deductions

Your "net income" for this calculation includes earnings after tax and NI, minus certain disregards (typically £5–£25 per week for a single earner, more for a lone parent or disabled worker). It also includes most benefits, pensions, and tariff income from savings above the lower capital limit.

The Income-Banded Method

Income-banded schemes avoid the complexity of applicable amounts and tapers. Instead, the council places your total household income into one of several bands — typically four or five — and each band gives a fixed percentage discount.

Rother District Council's 2026/27 scheme, for instance, uses these bands for a single person:

• Band 1 (up to £124.59/week): 100% discount
• Band 2 (£124.60–£190.18/week): 60% discount
• Band 3 (£190.19–£256.06/week): 40% discount
• Band 4 (over £256.06/week): 0%

The advantage is simplicity and stability. Small monthly fluctuations in Universal Credit do not constantly change your award unless they push you across a band boundary. The disadvantage is bluntness: if your income sits just above a boundary, you drop an entire band even though you are only pennies above the threshold.

How to Find Your Council's Method

Your council's working-age CTR scheme document — published on its website and adopted by Full Council each year before 11 March — sets out which calculation method it uses. Look for terms like "applicable amount," "taper," "percentage reduction" or "income band" in the scheme summary. If the scheme mentions applicable amounts and a 20% taper, it is means-tested. If it lists income brackets with fixed discounts, it is banded.

Some councils publish companion guides alongside the formal scheme, which are easier to read. Haringey's companion guide, for example, runs to over 100 pages but breaks the means-test calculation into step-by-step sections. Smaller councils may only publish the formal scheme document, which requires more effort to parse.

Why It Matters for Your Claim

Understanding the calculation method helps you predict your entitlement before you apply, spot errors on your decision notice, and identify the most effective challenge if your award seems too low. If you are on a means-tested scheme and your applicable amount is wrong — a missing disability premium, for instance — the entire taper calculation shifts in your favour.

If your council uses income bands and your income fluctuates monthly with Universal Credit, ask whether the council applies a de minimis rule or averaging period to prevent constant band changes. Some councils average UC income across two or three assessment periods, which smooths out the volatility.

The Council Tax Reduction in England guide walks through both calculation methods with worked examples for real council schemes, and the Local Scheme Rule Finder helps you record your own council's applicable amounts, taper rate or income bands so you can check the maths on your decision notice.
