The Council Tax Protocol for Wales Explained

Council tax in Wales is a property-based charge that raises over £2.8 billion a year towards the £11 billion cost of local services, and it is collected by your local council rather than by the Welsh Government¹. Each home sits in one of nine bands, A to I, based on what it was worth on 1 April 2003, the date used for Welsh valuations, while England and Scotland still use April 1991 values². The system itself began across Wales, England and Scotland on 1 April 1993³.

The Council Tax Protocol for Wales is the part of this that matters most when money is tight. It was launched in 2019, all councils in Wales have committed to following the standards it sets out, and all 22 Welsh authorities endorse it¹. It is best practice guidance on how councils should treat people who fall behind, including pausing bailiff action where someone is vulnerable or has a benefit claim outstanding. It is not a law that a court enforces, so it shapes how a council should behave rather than giving you an automatic right.

This page covers how the bill is worked out, how instalments work, what happens from the first missed payment to the whole year's bill falling due, why council tax is treated as a priority debt, and what can follow if arrears build up.

How council tax is worked out and billed

Three things decide what you pay: the valuation band for your home, how much your local council charges for that band, and whether you qualify for a discount or exemption from the full bill⁸. In Wales the band comes from the property's value on 1 April 2003, the last time Welsh properties were revalued, and the rules assume two or more adults are liable, which is why 50% of the basic bill is based on the band and 50% on household circumstances³. There are exceptions to the duty to pay, which is where discounts, exemptions and reduction schemes come in⁹.

Your council sends a bill in March showing what you owe for the coming financial year, which starts in April¹⁰. If the bill reaches you later than April, perhaps because you have moved house, you have less time to pay and may have to clear it in full before the end of the financial year in March¹⁰.

If you cannot pay, the first thing to do is tell the council rather than wait. Councils can let you pay in smaller amounts, and there is a separate Council Tax Reduction Scheme through which Welsh local authorities support low-income households with their bill⁷. An overpayment of Council Tax Reduction is treated as council tax arrears, so a change in circumstances that creates an overpayment can turn into a debt¹².

Paying in instalments: 10 or 12 months

Council tax is normally billed over 10 monthly instalments, which leaves a two-month break in February and March each year¹³. Councils may also accept weekly payments, and some accept weekly or fortnightly payments¹⁴. The annual bill is the same either way; spreading it changes the size of each payment, not the total.

You can ask to spread the same bill over 12 months instead of 10, which reduces what each instalment costs and removes the February and March break⁶. In England, councils must allow a 12-month spread if you prefer it; in Wales, councils may agree it¹⁵. Carers UK and Scope both describe the 12-month option as something you can ask for, and Macmillan's guidance for people dealing with debt says the same¹⁶.

If your bill arrives later than April, the 10-month pattern does not apply in the usual way, because there are fewer months left in the financial year to fit the payments into¹⁰.

Missing a payment: from reminder to the whole year's bill

Under the current Welsh rules, if you miss an instalment the council sends a reminder notice giving you 7 days to pay⁵. If you do not pay within those 7 days, you can become liable for the whole year's council tax instead of just the missed amount⁶. The Welsh Government has consulted on extending the minimum period to 62 days from one missed instalment to liability for the remaining annual balance, and confirmed in September 2025 that it would support that extension, so the 7-day rule reflects the position as it stands rather than a settled long-term one⁵.

Councils only need to send reminder notices for the first two missed payments in a financial year, which runs from 1 April to 31 March¹. Miss a third payment and you get a final notice instead, telling you to pay the full remaining balance in one go⁷. A missed payment after 31 December also triggers a final notice and the full remaining balance⁷. From 1 April 2026, if you miss a council tax payment in Wales, the council will send you a reminder notice²⁰.

Council tax is a priority debt

Council tax is a priority debt, whether it is your current bill or arrears from an earlier year⁷. That classification matters because it tells you the order to deal with things in: priority debts carry serious consequences if ignored, so they are usually handled before credit cards, overdrafts and other unsecured borrowing²². Council tax is a priority debt because the council has strong powers to make you pay²³.

The practical effect is that the ongoing bill and any arrears sit at the front of the queue. Where a council is chasing arrears, it will want the current year's council tax paid plus an extra amount to clear the older debt²⁴. If you are dealing with several debts at once, free and impartial help is available from MoneyHelper, from debt advice charities such as StepChange and National Debtline, and from Citizens Advice, and it costs nothing to ask²².

Arrears, bailiffs and IVAs: what can happen next

If arrears are not cleared, the council has a range of powers. It can take money from your pay or benefits, and it may send bailiffs to take things you own¹⁸. The debt can be secured against your home, the council can apply to make you bankrupt, and there is a risk of prison in England but not in Wales²². After bankruptcy, a council or HMRC might still use bailiffs to recover certain debts, and you will not be able to set up a payment arrangement with those bailiffs²⁶.

The Protocol is what sits between you and the sharpest end of that process. Where an enforcement agent suspects vulnerability, they should pause action and provide a report and any available evidence to the local authority, which then decides on next steps³. A pause in enforcement agent recovery should also take place where you have a legitimate and relevant outstanding claim for Council Tax Reduction, Universal Credit or Housing Benefit, or other relevant state benefits, that would clear or significantly reduce the balance³.

An Individual Voluntary Arrangement can include council tax arrears from previous years, and current-year arrears may also be included, with your IVA payments adjusted to reflect the change²⁷. Because the ongoing bill is a priority debt, an insolvency practitioner will look at how it is being paid as well as at the arrears going into the arrangement²⁷.

If you rent, council tax can be included in your rent where the tenancy agreement says so, but a landlord cannot require you to make a separate, additional payment to them for council tax²⁸. If you are a landlord in Wales, separate rules on energy efficiency carry a fine of up to £5,000 for renting out a property with a low energy rating or failing to comply with EPC duties, and a risk of losing your Rent Smart Wales licence³⁰.

If you are specifically asking whether non-payment can lead to prison in Wales, that is covered in Can you go to prison for not paying council tax in Wales?, and help for people in financial hardship is set out under debt.
