Plymouth Council Tax Reduction Change of Circumstances

The 21-Day Reporting Deadline

When your circumstances change in a way that could affect your Council Tax Support, you have 21 days to notify Plymouth City Council. Miss this window and you risk an overpayment demand — the council will recalculate your award back to the date the change actually happened, and the shortfall gets added to your bill.

Telling the DWP or HMRC about a change does not count. Plymouth City Council runs its own scheme independently. Even if you've updated your Universal Credit journal, you still need to report separately to the council.

What You Must Report

Any change that could shift your income band or alter your household composition:

• Income changes — a pay rise, reduced hours, starting or stopping overtime, losing a job, starting a new one
• Capital changes — savings crossing near or over £6,000, receiving an inheritance or redundancy payment, selling an asset
• Household changes — a partner moving in or out, a child turning 18, a non-dependant adult moving into your home, someone leaving
• Moving address — whether within Plymouth or out of the area entirely
• Starting or stopping self-employment
• Changes to benefits — new PIP or DLA award, ESA reassessment, sanctions

How to Report

Report changes online through Plymouth City Council's notification portal at plymouth.gov.uk/council-tax-support. You'll need your National Insurance Number and your 9-digit benefit reference number (the one starting with 5 or 6 from your Decision Notice).

How Overpayments Are Handled

If you report a change late and it means your CTS should have been lower, the council recalculates your award back to when the change occurred. The difference between what you received and what you should have received is an "excess award."

Plymouth doesn't chase this as a separate debt. Instead, the revoked discount is added back to your Council Tax account, increasing your balance for the year. The council then issues a revised demand notice spreading the higher amount across your remaining monthly instalments.

If you can't absorb the increased payments, the unpaid balance can trigger the standard enforcement sequence: reminders, a court summons (with costs added), a liability order, and eventually bailiff action.

When Changes Work in Your Favour

Not every change is bad news. If your income drops — reduced hours, job loss, a benefit increase — reporting it promptly can move you into a higher discount band. The council recalculates from the date of the change, potentially reducing your bill for the rest of the year.

Plymouth's banded system means small income fluctuations often make no difference — your discount only changes when income actually crosses a band boundary. A small amount of overtime may not shift your award if your assessed income stays within the same band. A significant change, such as starting or losing a job, can move you into a different band.

Protecting Yourself

Report changes as soon as they happen — don't wait for the 21-day deadline. If a change takes your combined capital to £6,000 or above, even temporarily, report it and explain the context. Plymouth's working-age scheme treats capital at or above that threshold as disqualifying.

Keep a record of every change you report — date, method, and what you told them. If a dispute arises later about whether you reported on time, that record protects you.
