Plymouth Council Tax Reduction Overpayment: What to Do When You Owe Money Back

An overpayment demand for Council Tax Reduction means Plymouth City Council recalculated your award and decided you were paid too much. The difference gets added back onto your Council Tax account as a debt — and the council can recover it through the same enforcement route as unpaid Council Tax, including court summonses and bailiffs.

Why Overpayments Happen

The most common cause is a change of circumstances that was not reported in time. Plymouth's Council Tax Support scheme recalculates your award whenever your income, household composition, or capital changes. If your wages increased, a non-dependant moved in, your savings crossed the £6,000 capital limit, or your Universal Credit award changed — and the council was not told promptly — the period between the change and the reassessment creates an overpayment.

Other causes include:

• Universal Credit changes — your monthly UC assessment and DWP-reported net earnings can affect the income used to calculate CTS. Report relevant changes directly to Plymouth City Council; do not assume the DWP has notified the council.
• Duplicate discounts — if you received both a CTS award and another discount you were not entitled to simultaneously, the council may claw back the overlap.
• Administrative errors — if you think the council made a mistake in the original assessment, raise it in a formal written grievance and ask for an explanation of the revised calculation.

Your Rights When You Receive an Overpayment Demand

The demand notice should tell you the period covered, the amount overpaid, and the reason. Read it carefully — if the reason is wrong or the dates do not match your circumstances, you have grounds to challenge it.

You can submit a formal written grievance. Send it directly to Plymouth City Council under Section 16 of the Local Government Finance Act 1992. Explain why you believe the calculation is wrong and include evidence that supports your case — payslips, UC statements, or proof of when you reported the change.

You can appeal to the Valuation Tribunal. If the council rejects your grievance or does not respond within two calendar months, you can appeal to the Valuation Tribunal for England (VTE). The tribunal is free and independent. It can consider whether the council applied the local scheme correctly and calculated your entitlement accurately.

Plymouth adds a past reduction back to your Council Tax liability, issues a revised demand notice, and redistributes the balance across the remaining monthly instalments. If you cannot afford the revised instalments, contact the council promptly about your account.

If You Think the Council Made an Error

If you think a council error caused the overpayment, include that in your written grievance and ask the council to explain how it calculated the revised Council Tax balance.

Preventing Overpayments

Report any change that could alter your Council Tax Support entitlement directly to Plymouth City Council within 21 days. Common examples include:

• Any change in your wages or hours
• Starting or stopping a job
• A new Universal Credit assessment showing different figures
• Someone moving in or out of your property
• Savings crossing the £6,000 threshold
• A change in disability benefit awards

The faster you report, the smaller any overpayment will be. If you are on Universal Credit, report relevant changes directly to the council rather than assuming that telling the DWP has fulfilled your reporting duty.

If you are dealing with an overpayment demand and are struggling financially, speak to a free debt advice service before ignoring it. StepChange, National Debtline, and Citizens Advice Plymouth can all help you understand your options.
