How Is Council Tax Reduction Calculated in Scotland?

The Six-Step Calculation

Every Scottish council follows the same calculation pipeline when assessing your CTR. Understanding these steps reveals how much you'll actually get — and whether a full 100% reduction is possible.

Step 1 — Establish your weekly council tax liability. The council takes your gross annual council tax bill (after any status discounts like the 25% Single Person Discount), divides by 52, and arrives at your net eligible weekly liability (L).

Step 2 — Calculate your applicable amount. This is the government's figure for what you need to live on. It combines your personal allowance with any disability premiums, carer premiums, family premiums, or work capability components that apply to your household.

Step 3 — Add up your countable weekly income. Net earned income (after tax, National Insurance, 50% of pension contributions, and earnings disregards) plus unearned income plus any tariff income from capital above the lower threshold.

Step 4 — Compare income against needs. If your total countable income is equal to or less than your applicable amount, you get maximum CTR — 100% of your net council tax liability (minus any non-dependant deductions).

Step 5 — Apply the taper. If your income exceeds your applicable amount, the excess is multiplied by 20%. This amount is deducted from your maximum CTR.

Step 6 — Subtract non-dependant deductions. Fixed deductions for any non-exempt adults living in the household come off the final figure.

What Counts as Income

Earned income includes wages, salary, overtime, bonuses, and self-employment profits. Before counting it, the council applies earnings disregards:

• £5 per week for a single person
• £10 per week for a couple
• £25 per week for a lone parent
• £20 per week if you or your partner receive a disability premium, carer premium, or work capability component
• An additional £17.10 per week if you work 16 or 30+ hours and qualify for the additional earnings disregard

Unearned income includes State Pension, private pension, tax credits, maintenance payments, and most other regular income. Universal Credit is assessed through a separate means-test pathway using DWP data feeds — the council takes your UC maximum amount and deducts your earned and unearned income under Part 6 of the regulations.

Disregarded income — not counted at all — includes Disability Living Allowance, Adult Disability Payment, Child Disability Payment, Pension Age Disability Payment, Child Benefit, the housing element of Universal Credit, and War Disablement Pensions.

The Applicable Amount (2026/27)

Your applicable amount is built from components. For a working-age single person, the base personal allowance is £92.80 per week. From there, premiums stack:

A disabled lone parent with one child and the Support Component would have an applicable amount of £92.80 + £83.24 + £22.00 + £50.35 = £248.39 per week. Their income would need to exceed that figure before the 20% taper starts reducing their CTR.

Worked Example: Partial Award

A single worker in a Band C property with net weekly liability of £30. Earnings: £210 per week net. Savings: £4,000 (below £6,000, so no tariff income).

1. Applicable amount: £92.80
2. Earnings disregard: £5 (single)
3. Countable income: £210 − £5 = £205
4. Excess income: £205 − £92.80 = £112.20
5. Taper: £112.20 × 20% = £22.44
6. CTR award: £30 − £22.44 = £7.56 per week

Worked Example: Maximum Award

A single UC claimant in a Band B property, no earnings, under £6,000 savings. Weekly liability: £25.

Their countable income through the UC assessment is below their applicable amount. No taper applies, no non-dependants present. CTR = £25 per week — 100% of the bill.

Why Scotland's Calculation Is Different

Unlike many English councils that cap working-age support at 75% or 80% of the bill, Scotland provides up to 100% across every band from A to H. There's no band cap. The taper rate is 20% nationwide. These aren't local council decisions — they're set in legislation by Scottish Ministers.

Running Your Own Numbers

Our Council Tax Reduction in Scotland guide walks through the full calculation for both working-age and pension-age households, with more worked examples covering couples, households with non-dependants, and disability premium stacking. It also explains how UC claimants are assessed differently from legacy benefit recipients, and how the Water Charges Reduction Scheme formula flows from your CTR award.
