The 6-year rule — what it actually says
Under the Limitation Act 1980, a council in England or Wales has six years from the date council tax fell due to apply for a liability order at the magistrates' court. If six years pass without the council obtaining one, the debt becomes "statute-barred" — the council can no longer get the order it needs to enforce, so the debt is effectively uncollectable.
Sounds promising. Here's the catch.
Why the rule rarely helps: liability orders
Councils are quick to obtain liability orders — usually within months of a missed bill, not years. And crucially: once a liability order has been granted, there is no time limit on enforcing it. A council can instruct bailiffs, deduct from wages or benefits, or take further action on a liability order that's 10 or 15 years old.
So when old council tax debt resurfaces — often after a credit file check, a house move, or a data-matching exercise — the first question isn't "how old is it?" but "did the council get a liability order at the time?" In most cases, they did.
What to do when old council tax debt resurfaces
- Don't ignore it — but don't pay in a panic either. Paying or acknowledging a debt can restart limitation clocks in some situations, so establish the facts first.
- Ask the council for details in writing: which property and billing years the debt relates to, when the liability order was obtained (with the court and date), and a full breakdown of the balance including any fees.
- Check the debt is actually yours. Old debts are prone to errors — wrong occupancy dates, joint liability with an ex-partner, discounts (like single person discount) never applied, or periods when you'd already moved out. Any of these can reduce or wipe the balance.
- If no liability order exists and 6+ years have passed, write to the council stating the debt is statute-barred under the Limitation Act 1980 and request they close the account.
- If a liability order exists, the debt is enforceable — but everything in the rest of this site still applies: affordable payment plans, write-off routes, and protections from bailiff action.
Scotland: a 20-year rule
In Scotland, council tax enforcement works through summary warrants rather than liability orders, and the limitation period is 20 years. Very old Scottish council tax debt is therefore usually still enforceable — but Scottish solutions (the Debt Arrangement Scheme, Protected Trust Deeds, sequestration) can deal with it.
Old debt, current pressure: your options now
If the resurfaced debt is enforceable and you can't clear it, you're in the same position as anyone with council tax arrears — with the same solutions:
- Affordable payment arrangement — councils can and do accept instalments on old liability orders; see payment plans;
- Section 13A hardship application — particularly relevant where the debt dates from a period of illness, abuse, or crisis; see write-off routes;
- A debt solution — old council tax arrears can be included in an IVA or DRO along with your other debts, stopping enforcement and writing off what you can't afford.
