Council tax is the only major British tax based on a valuation that is more than three decades old. Bands in England and Scotland reflect what a property was worth on 1 April 1991. Wales revalued in 2003 and has not done so since. Nothing about the system has been indexed, adjusted or reassessed in the interim, and almost every complaint about council tax being unfair traces back to that one decision.
How the bill is built
Three things determine what you pay. First, the band your property sits in, which is fixed. Second, the amount your local authority sets for a band D property, which changes annually. Third, the ratio between bands, which is set nationally and does not change.
That ratio is the source of the system’s regressive character. Band A pays six ninths of band D. Band H pays eighteen ninths, or exactly twice band D. So a property valued at forty thousand pounds in 1991 and one valued at several million pay amounts that differ by a factor of three, even though the underlying values differ by a factor of fifty or more. Analysis by the Institute for Fiscal Studies has repeatedly shown that council tax is, as a proportion of property value, substantially higher on cheap homes than expensive ones.
The bands themselves
In England the eight bands run from A, up to forty thousand pounds in 1991 values, to H, above three hundred and twenty thousand pounds. Scotland uses the same 1991 date with slightly different thresholds and reformed its higher-band multipliers in 2017 to make them steeper. Wales has nine bands based on 2003 values. Northern Ireland does not use council tax at all: it charges domestic rates based on individual capital values assessed in 2005, a genuinely different system.
You can check your band, and your neighbours’ bands, through the Valuation Office Agency band search. Neighbouring identical properties in different bands is common and is a legitimate ground for challenge.
Challenging a band
Band challenges are free and more often successful than people assume, but the grounds are narrow. You can challenge if the property has been demolished in part, if its use has changed, if the local area has changed materially, or if you believe the original 1991 assessment was simply wrong, which is usually evidenced by comparison with similar neighbouring properties. There is no charge and no need to use a paid reclaim company, most of which take a substantial percentage of any refund for filling in a form you could complete yourself.
Two cautions. A successful challenge can move a band down or up, and revaluation applies to the whole street pattern of evidence you cite. And a challenge based on the current market value of the property is automatically invalid, because the relevant date is 1991.
Discounts almost nobody claims
The single person discount of twenty-five per cent is well known. Several others are not. A property occupied only by full-time students is exempt. So is one occupied only by people under eighteen. Severe mental impairment, evidenced by a doctor and receipt of a qualifying benefit, can make an occupant disregarded for council tax purposes, and if that leaves one countable adult the discount applies. Annexes occupied by dependent relatives can be exempt. Properties undergoing major structural work may qualify for a reduction at the council’s discretion.
Separately, Council Tax Reduction is a means-tested scheme run locally rather than nationally, which means eligibility rules differ between authorities. The Citizens Advice council tax guidance is the most reliable place to check what applies where you live, and it also covers the disabled band reduction, which moves a property down one band where a room or facility is required for a disabled resident.
Why nobody revalues
Revaluation is technically straightforward and politically radioactive. Any revaluation creates losers whose bills rise sharply, concentrated in areas where property values have grown fastest, and those losers vote. Wales revalued in 2003 and the political experience discouraged repetition. Successive governments have commissioned analysis, including work published through the Local Government Association, and then declined to act.
What happens if you cannot pay
Council tax arrears are a priority debt, and the enforcement route is unusually fast: a missed instalment can lead to the full annual balance becoming due, followed by a liability order from the magistrates court and then enforcement agents. Contacting the council early almost always produces a payment arrangement, and requesting to pay over twelve months rather than the default ten reduces each instalment by twenty per cent at no cost. That option exists by right and is rarely advertised.
