THE PROPERTY FILTER TAKE

  • Keir Starmer resigned as PM on 22 June 2026; Andy Burnham became Prime Minister on 20 July, placing annual property tax reform at the top of the policy agenda.

  • The numbers are pointing to a significant structural shift: the Fairer Share model Burnham backs would charge £4,800 per year on a £500,000 buy-to-let property at the 0.96% investor rate, turning house price appreciation into a permanent, recurring liability rather than an unrealised gain.

  • You may wish to stress-test your portfolio against a value-based annual charge before the policy picture settles, and consider speaking to a qualified tax adviser about your capital gains exposure given the renewed debate over CGT alignment with income tax rates.

Keir Starmer resigned as Prime Minister on 22 June 2026. Andy Burnham took office on 20 July. The transition is not merely a political event. It represents a material shift in the tax risk landscape for property investors, brought by a new PM who has publicly backed replacing stamp duty and council tax with an annual levy tied to property values.

From One-Off Cost to Recurring Charge

The structural difference matters more than it might first appear. Under the current system, stamp duty land tax (SDLT - the government tax levied when buying property in England and Northern Ireland) is a one-off transaction cost. Investors absorb it at acquisition, factor it into their initial yield calculation, and move on.

The reform Burnham has endorsed works very differently. The Fairer Share campaign's model, which Burnham has repeatedly backed, would replace both SDLT and council tax with an annual levy. This is a recurring charge paid each year, based on the current market value of the property. Most residential properties would face a rate of 0.48% per year. Second homes, buy-to-let assets, and overseas-owned properties would pay 0.96%.

That distinction is significant. Under the current system, a buy-to-let investor pays SDLT once on entry and then holds the asset without further transaction-based taxation. Under the Fairer Share model, the same investor pays a charge that rises in line with the property's value every year. House price growth - which investors typically treat as unrealised capital appreciation - becomes a recurring tax event, not a deferred gain.

Knight Frank's head of UK residential research Tom Bill stated the risk plainly. "Annual revaluations will turn house price growth into an ongoing tax liability, which would inevitably affect decision-making." The psychological gap between a one-off SDLT bill and a permanent annual charge is significant, particularly in higher-value markets where the cost scales most sharply with appreciation.

What the Numbers Show

Fairer Share's own modelling puts the annual bills in concrete terms. A primary residence valued at £500,000 would face an annual charge of £2,400 under the 0.48% rate. A buy-to-let property at the same value would face £4,800 per year at the 0.96% investor rate. At £1 million, those figures reach £4,800 and £9,600 respectively.

The regional picture is uneven. Fairer Share's analysis shows a typical home in Newcastle facing approximately £860 per year at the standard rate. The same calculation produces roughly £1,300 in Manchester and almost £2,700 in London. In markets where values sit furthest above the national average, the annual cost becomes a material line in any yield calculation.

The Fairer Share model does include protections for lower-value homeowners. Their figures show 77% of households - approximately 18 million - would pay less than under the current council tax and SDLT system, with an average annual saving of £556. Any increase is capped at £1,200 per year. These safeguards offer limited comfort to investors holding portfolios of higher-value properties, where the 0.96% rate applies to the full asset value without that cap.

The stress test calculator can model how a fixed annual charge at different percentages affects net yield across your portfolio.

Capital Gains Tax: A Second Risk to Track

The proportional property tax is not the only policy uncertainty. Capital gains tax (CGT - the tax payable on profit when selling an asset) on residential property currently sits at 18% for basic-rate taxpayers and 24% for higher-rate taxpayers under HMRC's current rules.

A consistent thread in Burnham's stated economic thinking is that the UK over-taxes labour and under-taxes assets. Labour MP Louise Haigh, closely involved in organising the Burnham government's transition, has publicly called for CGT to be more closely aligned with income tax rates. Under full alignment, higher-rate taxpayers would face 40% on property gains - a 16 percentage point increase on the current position.

Burnham has not yet publicly committed to aligning CGT bands with income tax. His rival for the Labour leadership, Wes Streeting, made that proposal more explicitly. But the direction of travel matters for investors weighing exit timing. Our property investment strategies hub sets out how hold-period decisions interact with CGT rates under current and plausible future scenarios.

Positioning Your Portfolio in an Uncertain Environment

The UK house price data adds further context. Halifax reported year-on-year growth of 0.5% to May 2026. Nationwide's figure for the same period was 1.7% year-on-year. Both figures sit below the 2% to 4% growth range that Nationwide forecast at the start of 2026. Modest appreciation does not make property a poor investment. But it narrows the yield buffer available to absorb a new annual charge.

The risk with any leadership transition is an extended period of policy positioning. Both the proportional property tax and CGT alignment remain proposals rather than legislation. No transition timetable for either measure has been confirmed. However, the market has already spent the better part of two years in a holding pattern driven by elections, budget speculation, and policy leaks. A further period of uncertainty is the base case.

The stamp duty calculator remains the relevant tool for acquisition costs under current rules. For portfolio-level strategy, the deal sourcing software can identify assets where yield headroom provides more buffer against potential future charges. The negotiation and finance hub covers structuring options under changing tax conditions.

Key takeaways

- Andy Burnham became Prime Minister on 20 July 2026, bringing active backing for the Fairer Share proportional property tax - an annual levy of 0.48% on most residential properties, rising to 0.96% for second homes and buy-to-let assets. - A £500,000 buy-to-let property would face £4,800 per year at the 0.96% investor rate under the Fairer Share model, compared with a one-off SDLT charge under the current system. - UK house prices grew just 0.5% year-on-year to May 2026 (Halifax), narrowing the yield buffer that could offset a recurring annual charge. - CGT alignment with income tax rates is back on the policy agenda, with the higher rate potentially rising from 24% to 40% on residential property gains - a 16 percentage point increase. - Neither measure is confirmed legislation as of 21 July 2026, but investors holding high-value portfolios face the largest exposure and have the most to gain from modelling scenarios now.
