How Council Tax Works

Banding system: Properties are assigned to one of eight bands (A to H) in England, or nine bands (A to I) in Wales, based on their estimated value at a fixed date: 1 April 1991 for England and 1 April 2003 for Wales. England has not conducted a revaluation since the bands were established in 1993.

Fixed ratios: Tax liability varies by band according to set ratios relative to Band D. Band A pays 6/9 of the Band D amount, while Band H pays 18/9 (twice). This means the ratio between the highest and lowest bands is 3:1, regardless of actual property values. A property worth twenty times more than another can therefore pay at most three times as much Council Tax.

Local variation: Each local authority sets its own Band D rate annually to fund local services. Actual amounts payable therefore vary significantly between councils, but the relative burden across bands is fixed nationally.

Policy evaluation: The Institute for Fiscal Studies (Adam et al., 2020) has noted that the frozen 1991 valuations cause substantial divergence between Council Tax liability and current property values, particularly in areas where prices have risen faster than the national average. The Mirrlees Review (IFS, 2011) examined Council Tax within the broader context of property taxation reform and recommended moving towards an annually revalued proportional property tax.

Revenue-Neutral Proportional Rate

Each council page models what a proportional annual tax on current property values would look like for that authority, calibrated to raise the same revenue as current Council Tax. This is an analytical scenario showing how the tax burden would be redistributed across bands, not a policy proposal. The methodology is set out on each council page.

Strengths and Weaknesses

The following analysis examines Council Tax across three dimensions: administrative practicality, distributional effects, and incentive effects. It draws on the academic and institutional literature to present an evidence-based assessment.

Strengths

Administrative simplicity and revenue stability

Council Tax is operationally cheap to run. The banding model means the Valuation Office Agency need not conduct annual reassessments of the entire housing stock; band determinations are largely a one-off exercise. As a result, collection costs are very low relative to the revenue raised, and local authorities can budget confidently on the basis of a predictable and stable yield. The system has proved durable: Council Tax replaced the Community Charge in 1993 and has remained broadly unchanged since, which itself reflects a degree of practical resilience.

Targeted relief mechanisms

The system includes significant built-in protections for lower-income and vulnerable households. A 25% single-occupier discount, full exemptions for students and the severely mentally impaired, and the Council Tax Support scheme, through which local authorities can reduce or eliminate liability for households on low incomes, provide meaningful distributional mitigation. These mechanisms are administered at local level, allowing councils some flexibility to design relief structures appropriate to their population.

No disincentive to transaction

As an annual holding tax rather than a transaction tax, Council Tax does not penalise owners or occupiers for moving. Unlike Stamp Duty Land Tax, it creates no direct financial barrier to transaction and therefore does not contribute to the lock-in effects documented in the transaction-tax literature. This is an underappreciated structural advantage: the tax is recurrent and therefore reflects ongoing occupation rather than the incidental event of purchase.

Weaknesses

Regressivity of the band structure

The compression of the band ratio to 3:1 (Band A to Band H) is the most analytically significant structural feature of Council Tax. A Band H property pays at most twice the Council Tax of a Band A property, regardless of actual market values; a property worth twenty times another may pay as little as three times as much. Adam et al. (IFS, 2020) documented this regressivity systematically, showing that Council Tax as a share of current property value falls steeply with the value of the property. The burden therefore falls most heavily on owners and occupiers of lower-value properties relative to their asset; an outcome that is difficult to defend from the principles of horizontal or vertical equity.

Frozen valuations disconnected from current values

England's banding was established in 1993 on the basis of estimated 1991 property values and has never been revalued. Over thirty years of differential house price growth means that banding no longer reflects relative property values in any systematic way. Areas where prices have risen fastest, particularly London and parts of the South East, have seen the largest divergence between Council Tax liability and actual value. The IFS has noted that this divergence means the tax no longer achieves even its original, modest degree of value-proportionality. Wales conducted a revaluation in 2003 and introduced a ninth band (Band I); England's failure to follow suit is a documented structural weakness that compounds over time.

Political obstacles to reform

Although Council Tax is analytically deficient in well-understood ways, the path to reform is exceptionally difficult. Any revaluation would produce large bill increases for properties in rapidly appreciating areas, and large reductions elsewhere. Long-tenure owner-occupiers on fixed incomes in high-value properties face a genuine distributional problem if revaluation were to proceed without compensating relief. This creates a strong and enduring political barrier to reform, meaning the analytical case, well established in the Mirrlees Review and subsequent IFS work, has not translated into legislative action. The frozen base is therefore not merely a technical failure but an institutional one.
