Council tax intake could soar 43% by 2030 – ‘adding £500 to the average bill’
Treasury forecasts indicate that council tax receipts could rise by 43% to £58.8bn by 2030/31, prompting Conservative claims that average band D bills could increase by about £556. The figures have intensified political disagreement over local taxation and planned devolution, though the government says no future council tax rates have been set.
Councils collected £41.2bn in council tax in 2024/25; the forecast implies a £17bn increase over five years. Sir James Cleverly argued Labour had effectively built rises into its plans and warned that greater fiscal powers for mayors could increase bills, while Louise Haigh dismissed this as “nonsense” and ministers stressed that councils set their own rates. The government’s proposals would let mayors retain shares of locally raised income tax and business rates without changing taxpayers’ income-tax rates, alongside an equalisation system for lower-revenue areas.
In short
- Council tax receipts are forecast to reach £58.8bn by 2030/31.
- Conservatives estimate average band D bills could rise by £556.
- Ministers say councils have not set rates beyond this year.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The Conservative argument identifies a genuine structural concern: whilst councils formally set their own rates, devolution combined with fiscal pressure creates strong incentives making council tax rises effectively inevitable rather than truly optional. If councils lack sufficient alternative revenue and face service demands, raising bills becomes the path of least resistance, suggesting the government's fiscal architecture produces this outcome even if councils technically choose it. The structure shapes the outcome as surely as explicit policy.
The case against
Labour correctly emphasises that councils are genuinely independent and set their own rates—governments cannot force increases whatever structural pressures exist. The Treasury forecast reflects technical inflation and property adjustments, not policy choices, and the government's devolution of income tax and business rates actually expands councils' fiscal flexibility. Taking the Conservative argument seriously would argue against any meaningful devolution, since local autonomy inevitably means councils sometimes make choices governments dislike; democratic localism requires accepting councils' genuine independence.
Explained simply
Council tax is a local charge paid by households in England, with bills based partly on the value band of a home. Councils use the money to fund local services such as rubbish collection and social care, and each council sets its own rate.
The Treasury’s forecast is about the total amount councils may collect, rather than a decision to raise individual bills. The Conservatives say the projected increase could mean higher bills, while ministers say no future rates have been set. Mayors are also due to gain powers to keep some locally raised income tax and business rates, with a system intended to support areas that raise less revenue.
