Andy Burnham's Tax and Property Proposals: What Homeowners and Taxpayers Should Know

TAX & REGULATION

What has actually changed in government

Keir Starmer remains Prime Minister as of early July 2026, but announced on 22 June that he would resign once a successor is chosen. Andy Burnham, the former Mayor of Greater Manchester who returned to Parliament via a by-election on 18 June and was sworn in as an MP on the same day Starmer's resignation was announced, is so far the only declared candidate in the resulting Labour leadership contest. Because he is unopposed, Burnham is widely expected to become Prime Minister without a formal leadership vote, with commentary suggesting this could happen by around 20 July 2026. He has not published a tax manifesto, and no government policy document setting out his tax plans exists. What is available is a series of speeches and interviews, including his first major policy speech in Manchester on 29 June, which give an indication of his general direction rather than a confirmed programme for government. Everything in this article describes reported positions and past statements, not enacted policy, and none of it currently changes what any taxpayer owes.

What Burnham has said about property taxation

The area where Burnham's thinking is most developed concerns property. He has described council tax as highly regressive, pointing out that a household in a Band D property in Greater Manchester can pay more council tax in cash terms than a household in one of the most expensive parts of London, because council tax bands are still based on 1991 property valuations that have never been updated. He has said he has long been persuaded of the case for a land value tax, an annual charge based on the value of land itself rather than any building on it, which supporters argue encourages land to be used productively rather than held vacant. Burnham has previously suggested such a tax could be used to replace stamp duty land tax entirely, removing the upfront cost that currently applies when a property changes hands.

Council tax, stamp duty and the proportional property tax idea

Burnham has also expressed support for the Fairer Share campaign's proposed proportional property tax, which would replace both council tax and stamp duty with a single annual charge of 0.48% of a property's assessed value, rising to 0.96% for second homes, empty properties and overseas-owned property. Under the standard rate, a property valued at £3 million would attract an annual charge of approximately £14,400, a significant increase for owners currently paying council tax at a fixed band-based amount. The campaign's model includes a cap for existing owners, so bills would not rise sharply overnight, with the cap only lifting once a property is sold, meaning the largest impact would fall on future buyers rather than current owners. No version of this proposal has been legislated, and property experts quoted in trade coverage broadly expect any implementation, if it happens, to be timed for the period following the next general election, expected in 2029 at the latest.

Capital gains tax, income tax and the wider fiscal picture

Beyond property, Burnham's broader fiscal position has focused on shifting taxation from income toward wealth and assets, though the specifics remain less developed than his property proposals. He has previously argued there is definitely a case for reintroducing a 50p top rate of income tax, while more recently signalling adherence to Labour's existing manifesto commitment not to raise income tax, employee national insurance or the main rate of VAT on working people. In September 2025, while still Mayor, he proposed a 10% starting rate of income tax for lower earners, which would tax part of the band currently charged at 20% at a lower rate instead, amounting to a tax cut rather than a rise for that group. Some figures reportedly close to his transition team have also floated aligning capital gains tax more closely with income tax rates and ending a specific relief that currently reduces CGT on inherited assets, though Burnham himself has not confirmed either as his own policy.

What is confirmed policy versus reported proposal

One measure is worth separating from the reported proposals because it is already enacted policy rather than a Burnham idea: the November 2025 Budget introduced a high-value council tax surcharge, sometimes described as a mansion tax, charging an extra £2,500 to £7,500 a year on homes worth £2 million or more from April 2028. That surcharge was legislated under the Starmer government before the June 2026 leadership change and is separate from any land value tax or proportional property tax that Burnham has spoken about, though independent analysts have noted it raises a comparatively modest amount, estimated at around £400 million a year, against the far larger sums Burnham's wider property tax ideas could theoretically generate if implemented in full.

What this could mean for taxpayers, and the timeline involved

For taxpayers, the practical position in July 2026 is that nothing has changed yet. No land value tax, proportional property tax, or capital gains tax realignment has been put before Parliament, and any of these would require primary legislation, a process that typically takes months even once a government formally commits to a policy. Property analysts have suggested that owners of higher-value homes and second properties may wish to review their long-term exposure given the clear direction of travel in Burnham's public statements, without necessarily expecting any near-term change to their bills. HMRC's most recent estimate puts the UK tax gap, the difference between tax collected and tax that should theoretically be due, at £59.2 billion, or 6.4% of total tax liabilities, a figure some economists in the tax policy debate have suggested could be a lower-controversy way to raise revenue compared with new taxes, though closing it in practice depends on HMRC enforcement capacity rather than a change in tax rates.

Is Andy Burnham the Prime Minister yet?

No. Keir Starmer remains Prime Minister as of early July 2026, continuing in office until a successor is chosen. Andy Burnham is the only declared candidate in the Labour leadership contest and is expected to take over, most likely without a formal vote, by around 20 July 2026.

What is a land value tax and has Burnham proposed one?

A land value tax is an annual charge based on the value of land alone, excluding buildings. Burnham has said he has long supported the idea, and has suggested it could replace stamp duty, though no legislation has been tabled.

Is the council tax mansion tax surcharge part of Burnham's proposals?

No. The surcharge on homes worth £2 million or more from April 2028 was introduced in the November 2025 Budget under the Starmer government, separate from any Burnham property tax proposal.

Will capital gains tax rise under a Burnham government?

Some figures reportedly close to Burnham's transition team have floated aligning CGT more closely with income tax, but Burnham has not confirmed this as his own policy, and no legislation exists.

When could any of these tax changes actually take effect?

None have been legislated. Property experts broadly expect any major reform, if pursued, to be targeted at the period after the next general election, expected by 2029 at the latest.
