Non-Dependant Deductions and Council Tax Reduction in Hounslow

What a Non-Dependant Deduction Actually Is

When another adult lives in your home and they're not your partner or a paying lodger, the council treats them as a "non-dependant." That typically means an adult son, daughter, elderly parent or other relative sharing your property. For working-age claims, Hounslow applies a fixed weekly deduction for each qualifying non-dependant; the amount depends on whether they are in remunerative work, not their income. Pension-age claims use income tiers.

The deduction reduces the amount of support you receive, not the council tax bill itself. So if you qualify for 75% support under Band 1, a non-dependant deduction chips away at that 75% figure.

How Deduction Rates Work

For working-age claims in Hounslow, Part 7, Paragraph 27 of the adopted scheme sets the deduction at £10 per week for a non-dependant aged 18 or over who is in remunerative work, and £5 per week otherwise. Hounslow defines remunerative work as averaging at least 16 hours a week. This working-age deduction is not tiered by earnings. For pension-age claims, the prescribed rules use gross weekly income tiers, so higher income can mean a higher deduction.

The council applies one deduction per qualifying non-dependant, but only one deduction for a non-dependant couple. If two adult children live with you, that's two separate deductions from your award. The combined effect can significantly reduce — or in some cases eliminate — your Council Tax Reduction entitlement.

When the Deduction Is Waived Entirely

The exemptions differ between pension-age and working-age claims:

• For pension-age claims, no deduction is made if the claimant or their partner is blind or receives PIP daily living component, Attendance Allowance or DLA care component.
• Under the pension-age rules, no deduction is made for a full-time student or a non-dependant receiving Income Support, State Pension Credit, income-based Jobseeker's Allowance, income-related Employment and Support Allowance, or Universal Credit calculated with no earned income.
• A non-dependant's PIP, Attendance Allowance or DLA is disregarded when calculating a pension-age income-tier deduction; receiving one of these benefits does not by itself remove a deduction if they have other income.
• No deduction applies to someone under 18; Hounslow's working-age deduction rates apply to qualifying non-dependants aged 18 or over.

If a non-dependant's income or benefit status, or your own circumstances, change, report it so the council can reassess the deduction under the rules for your claim.

Adult Children Moving Home

This is the most common scenario. An adult child returns from university or moves back after a relationship breakdown. The council doesn't care about the reason — what matters is whether they're now a non-dependant under the scheme rules.

If your adult child is not in remunerative work, the working-age deduction is £5 per week; if they are in remunerative work, it is £10 per week regardless of their salary. Pension-age claims use the prescribed income tiers.

What catches people out: the deduction applies from the date the non-dependant moves in, not from the date you report it. Delayed reporting doesn't buy you extra support — the council will backdate the deduction and you could face an overpayment.

The same logic works in reverse. When an adult child moves out, report it immediately. The deduction should be removed from the date they left, which may increase your support.

Reporting Changes and Protecting Your Award

Any change in household composition must be reported to Hounslow Council promptly. The main triggers:

• A non-dependant moves in or out
• A non-dependant's income changes significantly (new job, job loss, benefit award)
• A non-dependant starts or stops receiving a qualifying disability benefit

Report changes through the online revenues portal or by contacting the council at 020 8583 2211. Late reporting risks overpayment recovery — the council can claw back support you weren't entitled to receive.

The Bigger Picture

Non-dependant deductions are one of the most complained-about features of Council Tax Reduction schemes nationwide. The deduction assumes the non-dependant contributes to household costs, but plenty of adult children living at home are saving for a deposit or paying off student debt, not handing over cash for bills.

You can't opt out of the deduction — it's applied by formula. But you can make sure the council has accurate information about every non-dependant's income and disability status, because getting the deduction rate wrong in either direction creates problems. An overstated deduction costs you money; an understated one creates an overpayment the council will eventually recover.
