Cornwall Council Tax Reduction for Couples — How Joint Assessment Works

When you live with a partner in Cornwall — married, civil partners, or cohabiting — Cornwall Council treats you as a single household for Council Tax Support purposes. Both your incomes, savings, and capital are combined into one assessment. This joint assessment changes how much support you get and who counts as a non-dependant versus a partner.

Partner Aggregation: What Gets Combined

Cornwall Council adds together:

• All earned income from both partners (after tax, NI, and the standard earnings disregard)
• All unearned income — benefits, pensions, maintenance, rental income from both of you
• All capital and savings — every bank account, ISA, premium bond, and non-primary property held by either of you

If your combined capital is £6,000 or more, neither of you qualifies for Council Tax Support. That threshold applies to the household total, not per person. A couple with £4,000 each in savings has £8,000 combined and gets nothing.

The Applicable Amount for Couples

Cornwall Council sets a higher personal allowance for couples than for single claimants. The couple's Applicable Amount includes a joint personal allowance plus any premiums that apply (disability, carer, severe disability).

The earnings disregard is £10 per week for a couple, compared to £5 for a single person. It is £20 for lone parents, and can be up to £25 for claimants who qualify for specific disability or carer premiums.

Because the Applicable Amount is higher for couples, having a partner doesn't automatically mean less support. A low-income couple where neither partner works may still receive the full 75% award. The taper only kicks in when combined income exceeds the combined Applicable Amount.

One Partner Working, One Not

This is where the 20% taper rate bites. If one partner earns, say, £80 per week above your joint Applicable Amount, the council reduces your award by £16 per week (20% of £80). But the couple's higher Applicable Amount partially offsets this — for the same income, a single person could have more income above the lower baseline.

If one partner claims Universal Credit while the other works, Cornwall Council takes the full UC award and the partner's earnings into the joint assessment. The UC housing element is disregarded, but the standard UC allowance counts.

Mixed-Age Couples

If one of you has reached State Pension age and the other hasn't, you're normally assessed under the working-age scheme. That means the less generous rules apply — the 75% cap, £6,000 capital limit, and zero backdating.

The exception: if you've been continuously claiming Income-based Pension Credit since before May 2019, you stay on the pension-age scheme with its 100% maximum award and £16,000 capital limit.

What Counts as a Couple

Cornwall Council treats you as a couple if you're married, in a civil partnership, or living together as if you were. If you share a home but live independently (separate finances, separate living arrangements), you can ask the council to assess you as single occupants — but you'll need to demonstrate the arrangement clearly.

The distinction matters beyond the income test. A partner isn't a non-dependant. Non-dependant deductions (£5–£15.95 per week) apply to other adults in the household — adult children, siblings, friends — not to your partner. Your partner's income goes straight into the joint assessment instead.
