Part of: UK Council Tax 2026 — Complete Guide → Council Tax Arrears 2026
TL;DR: Under section 9 of the Limitation Act 1980, Council Tax debts become time-barred and unenforceable after 6 years from the date they became payable - provided there has been no written acknowledgement of the debt and no payment within that period. Any payment or written acknowledgement restarts the 6-year clock. This is a legal defence, not an automatic write-off.

The Limitation Act 1980 and Council Tax
Section 9 of the Limitation Act 1980 states that an action to recover a sum of money cannot be brought more than 6 years from the date on which the cause of action first accrued. For Council Tax, the cause of action accrues when each instalment or balance becomes payable.
What this means in practice: A billing council cannot bring court proceedings (apply for a summons and liability order) to recover a Council Tax instalment that became due more than 6 years ago - provided the debtor has not acknowledged the debt or made any payment during the 6-year period.
This is a significant legal protection. However, it is a defence that must be actively raised - the debt does not automatically disappear when 6 years pass.
The "Becomes Payable" Calculation
The limitation clock starts from the date each Council Tax amount became payable:
For missed instalments: From the date each monthly instalment fell due. If January 2019 and February 2019 instalments were missed and never paid, the 6-year limitation on those specific instalments runs from January and February 2019 respectively.
For the annual balance: Where the full year's balance became due (after loss of instalment rights under Regulation 23 of the Council Tax (Administration and Enforcement) Regulations 1992), the limitation runs from that date.
For liability orders: The position of a liability order under the limitation period is more complex. A liability order is a court order, and the limitation period for enforcing court orders differs from the limitation period for bringing the original action. If a liability order has been granted, seek specific debt advice on the limitation position.
The Acknowledgement Restart Rule
Under section 29 of the Limitation Act 1980, the 6-year limitation period restarts from the date of the most recent acknowledgement or payment:
Written acknowledgement: Any written communication from the debtor that acknowledges the existence of the debt can restart the clock. Writing to the billing council saying "I know I owe this Council Tax but I cannot pay" may constitute an acknowledgement.
Any payment: A payment of any amount toward an old Council Tax debt restarts the clock from the payment date. Even a small payment made "to show goodwill" or "in good faith" toward a very old debt can restart the limitation period, converting a time-barred debt into an enforceable one.
Practical rule: Seek debt advice before making any payment on or written reference to a debt that may be approaching or past the 6-year mark.
How to Raise the Time-Bar Defence
At the summons stage: If you receive a summons for a debt you believe is time-barred, submit a written defence to the magistrates court before the hearing date. Cite section 9 of the Limitation Act 1980 and state the date the debt became payable and the absence of any acknowledgement or payment within 6 years.
At the liability order stage: If a liability order has already been granted and the underlying debt was time-barred, the position is more complex. There are limited routes to set aside a liability order. Seek specific legal advice.
At the bailiff stage: If enforcement agents attend in relation to an old debt, you can write to the billing council asserting the time-bar and requesting that enforcement be suspended pending review. Include evidence of when the debt became payable and the absence of acknowledgement or payment.
The High Bar for Asserting Time-Bar
Billing councils are aware of the limitation period and typically argue that the clock was restarted by some form of acknowledgement or payment. Common council arguments:
- A CTR application or discount application mentioning the debt
- A payment arrangement discussion where the debtor referenced the debt
- A partial payment (even a small one)
- Electoral roll or Council Tax registration data linked to the debt period
Before asserting the time-bar, carefully review all communications with the billing council over the relevant period. A debt advice charity can help you assess whether the time-bar applies cleanly.
How to Check Whether the 6-Year Limitation Has Run Cleanly
Before asserting the time-bar defence, you need to establish:
1. When the debt became payable: Identify the specific instalment dates or the date the full balance became due.
2. Whether any payment was made since then: Review your bank records for that period. Even a small payment toward the debt restarts the clock.
3. Whether any written acknowledgement was made: Review any correspondence you sent to the billing council in the period. Letters, emails, or online messages that reference the debt could count as acknowledgement.
4. Whether the council obtained a liability order: If so, the limitation position regarding enforcement of the order differs from the limitation for the original action.
Free debt advice charities (Citizens Advice, National Debtline) can help you work through this analysis. Do not make any payment or send any written communication acknowledging the debt until you have assessed the limitation position.
Scotland: Different Prescription Rules
Scotland has its own prescription and limitation rules under the Prescription and Limitation (Scotland) Act 1973. The prescriptive period for Council Tax in Scotland is 5 years (not 6) under the short negative prescription. If you are in Scotland, seek advice from Citizens Advice Scotland or a Scottish solicitor on the applicable rules.
The Debt Advice Charities' Role
Debt advice charities (StepChange, Citizens Advice, National Debtline) can help you assess whether the Limitation Act 1980 applies to your specific situation. They can:
- Review the timeline of the debt and any payments or acknowledgements
- Confirm whether the time-bar appears to apply
- Advise on how to communicate with the billing council
- Help you draft a letter asserting the time-bar defence if appropriate
Do not rely solely on your own analysis of the limitation position without seeking advice, particularly if the situation is complex or if the billing council disputes the limitation.
Practical Context: When This Is Most Relevant
The 6-year rule is most relevant where:
- A person moved and lost track of Council Tax at an old address
- A billing error resulted in a debt not discovered until much later
- A council has significantly delayed pursuing a debt
- A debt relates to a period of confusion about liability (for example, a disputed tenancy period)
For people managing current debts or recent arrears, the 6-year limitation is not immediately relevant. It becomes important where older debts surface unexpectedly.
Frequently Asked Questions
If my Council Tax debt is now 7 years old and I haven't paid or acknowledged it at all, is it legally gone?
Not automatically. The debt still technically exists on the billing council's records; the council simply cannot enforce it in court proceedings. You would need to actively raise the Limitation Act 1980 section 9 time-bar as a legal defence if the council attempts enforcement action. If you are unsure whether the limitation has run cleanly, seek advice from Citizens Advice or National Debtline before taking any action.
I wrote to the council about an old debt 3 years ago saying I acknowledged owing it - does this restart the clock?
A written acknowledgement of the debt under section 29 of the Limitation Act 1980 restarts the 6-year clock from the date of the acknowledgement. If you wrote acknowledging the debt 3 years ago, the new 6-year period runs from that date (expiring approximately 3 years from now). Seek advice to confirm whether your specific communication constituted a valid acknowledgement.
Can I use the 6-year rule to get a liability order set aside?
Only in very limited circumstances. If the underlying debt was already time-barred when the summons was issued (and you had a valid time-bar defence that was not raised at the hearing), you can apply to the magistrates court for a set-aside. This is complex and likely requires legal advice.
The billing council is chasing me for Council Tax debts from 2017 - is this time-barred under the Limitation Act?
If the 2017 instalments became payable in 2017 and there has been no payment or written acknowledgement since, the 6-year limitation under section 9 of the Limitation Act 1980 would have run by 2023. Seek specific debt advice to verify whether any payment or acknowledgement may have restarted the clock. Do not make any payment or written acknowledgement until you have assessed the limitation position.
Does the time-bar apply in Scotland?
Scotland has its own prescription rules under the Prescription and Limitation (Scotland) Act 1973. The prescription period for Council Tax in Scotland is different from the Limitation Act 1980 rules. If you are in Scotland, seek advice from Citizens Advice Scotland.
How we verified this
The 6-year limitation period for Council Tax debts is from section 9 of the Limitation Act 1980. The acknowledgement restart rule is from section 29 of the same Act. The Council Tax (Administration and Enforcement) Regulations 1992 governs the recovery process within which the limitation period applies. Citizens Advice and National Debtline provide practical guidance on asserting the time-bar defence. The IRRV provides professional guidance for billing council debt recovery teams. MHCLG publishes guidance on Council Tax recovery practice and the Council Tax protocol, which encourages billing councils to apply limitation principles fairly when reviewing aged debts.
