Council Tax Reduction Non-Dependant Deductions in Wigan: Who Counts and How Much

What Non-Dependant Deductions Are

A non-dependant is an adult who lives with you but isn't your partner and isn't financially dependent on you — typically an adult child, a sibling, a parent, or a friend sharing the house. When a non-dependant lives in your home, Wigan Council assumes they contribute toward the Council Tax, whether they actually do or not.

The council subtracts a fixed weekly amount from your gross CTR award before paying it. This deduction is based on the non-dependant's income and employment status, not on whether they hand you any money. If your 25-year-old son works full-time and earns £450 a week but doesn't contribute a penny to household bills, the council still deducts the full amount from your award.

How Much Gets Deducted

Non-dependant deductions depend on the non-dependant's gross weekly income and employment status:

• On income-based JSA, ESA (income-related), or Universal Credit without earnings: Lowest deduction band
• Earning below the first threshold: A modest weekly deduction
• Earning above higher thresholds: Progressively larger deductions, up to the maximum band

Check Wigan Council's current information for the amount that applies to your household.

Each non-dependant triggers a separate deduction. Two adult children living with you means two deductions from your award — which can significantly erode or eliminate your CTR.

When No Deduction Applies

Several circumstances exempt you from non-dependant deductions entirely:

• You receive PIP daily living component or Attendance Allowance. This is the most common exemption. If the main claimant (or their partner) receives either benefit, no deductions are made for any non-dependant in the household, regardless of their income.
• The non-dependant is under 18
• The non-dependant is a full-time student

The PIP exemption is important because many disabled residents don't realise they're protected. If you receive PIP daily living and have working adult children at home, your CTR should not be reduced for their presence.

The Practical Problem

Non-dependant deductions create a specific tension in multi-generational households. An adult child who earns a reasonable wage triggers a deduction from your CTR, but they may not actually give you money for bills. The council doesn't care whether the non-dependant contributes — the deduction happens automatically based on their income.

If the non-dependant refuses to contribute, you absorb the loss. The Council Tax Reduction deduction applies regardless of whether they give you money; any household contribution arrangement is separate.

The practical responses are limited: ask the non-dependant to contribute at least the deduction amount, check whether any exemptions apply, or accept the reduced CTR and budget around it.

Reporting Non-Dependant Changes

You must report to Wigan Council when a non-dependant moves in or out, or when their income changes significantly. A non-dependant moving out means your deduction disappears and your CTR should increase. A non-dependant starting a higher-paid job means a larger deduction from your next assessment.

Report changes directly through wigan.gov.uk — telling the DWP or any other department doesn't count. Delays in reporting can result in overpayments being added back to your Council Tax account.
