Land value tax, council tax reform and your financial plan

UK property tax reform is back in the spotlight. The debate has sharpened because Andy Burnham is being discussed as a possible future Labour leader and prime minister, and he has previously supported reform of council tax, stamp duty and land taxation. But this is not one settled policy. It is a collection of overlapping ideas, campaign proposals and existing government changes.

The phrase land tax is often used loosely. In practice, the current debate includes at least four different things: a land value tax based on the land itself, a proportional property tax based on the value of the whole property, council tax revaluation or band reform, and changes to stamp duty.

The right response is not to assume that one particular tax will definitely arrive. The better response is to understand the possible directions of travel and model the impact on your own financial plan.

Council tax in England is still based on what homes were worth on 1 April 1991. Wales uses 1 April 2003 values. This means English council tax bands are based on property values that are now more than three decades old. In England, Band H starts at more than £320,000 in 1991 values, even though many homes now worth far more than that remain within the same top band.

The Institute for Fiscal Studies has described council tax in England as out of date, arbitrary and highly regressive with respect to property values. One key problem is that Band H properties pay only three times as much tax as Band A properties, even though Band H properties were worth at least eight times as much even in 1991, and often much more today.

Council tax is also a major funding source for local government. That makes reform politically difficult. Any replacement would need to decide who pays, who gains, who loses, how local services are funded, and how households are protected during the transition.

Stamp Duty Land Tax is charged when property is bought in England and Northern Ireland. It is charged in slices, and additional charges usually apply when buying additional residential property or when a non-UK resident buys residential property.

Stamp duty raises money, but it can also discourage people from moving. It can affect downsizing, relocating for work, divorce and separation, buying a larger home for a growing family, moving closer to relatives, or buying a more suitable home in later life.

That is why some reform proposals try to reduce or replace stamp duty with an annual property-based charge. This would change the balance between upfront costs and ongoing costs.

A land value tax is an annual tax on the underlying value of land, rather than the building on it. The argument is that land value often rises because of location, infrastructure, planning permission and wider economic growth, not only because of the owner's effort.

A proportional property tax is simpler to understand. It taxes the current value of the residential property, usually at a set percentage. This is not the same as a true land value tax because it is based on the value of the whole property, not just the land underneath it.

Council tax reform could be less radical. Instead of replacing council tax entirely, government could update property valuations, add new bands, change rates for higher bands, or increase charges on second homes and empty homes.

Stamp duty reform would focus on the cost of moving. It could reduce transaction taxes and replace some of the revenue with an annual property charge.

The campaign group Fairer Share has proposed replacing council tax and stamp duty with a Proportional Property Tax of 0.48% of property value. Its proposal also includes a higher 0.96% rate for second homes, empty homes and non-resident-owned homes, shifting payment responsibility from tenants to property owners, and allowing deferral for owners unable to pay immediately. Source: https://committees.parliament.uk/writtenevidence/10314/pdf/

At 0.48%, a £250,000 property would face an annual charge of £1,200, a £500,000 property would face £2,400, a £1 million property would face £4,800, and a £2 million property would face £9,600.

At 0.96%, which has been proposed for second homes, empty homes and non-resident-owned homes, those annual charges would double. A £500,000 second home would face an illustrative annual charge of £4,800, and a £1 million second home would face £9,600.

Another route is to keep council tax but make it more progressive. The IPPR has proposed increasing council tax rates for higher bands while reducing bills for households in lower bands. This would be an adjustment to the current system rather than a full land tax or full proportional property tax. Source: https://www.ippr.org/articles/towards-a-fair-and-proportional-property-tax

This type of reform would still matter for planning. Households in higher-value bands could face higher recurring costs, while households in lower bands could see modest reductions.

Government has also announced a planned High Value Council Tax Surcharge from April 2028 for owners of residential property in England worth £2 million or more. This is separate from current council tax bands and shows that higher-value homes are already in scope for targeted reform.

Second homes and empty homes are already being treated differently in parts of the tax system. In England, councils have stronger powers to charge premiums on long-term empty homes, and from April 2025 councils have been able to charge a premium of up to 100% additional council tax on second homes. Source: https://www.gov.uk/government/publications/long-term-empty-homes-and-second-homes-council-tax-premiums-and-exceptions/guidance-on-the-implementation-of-the-council-tax-premiums-on-long-term-empty-homes-and-second-homes

For council tax purposes, a second home is generally a substantially furnished dwelling with no resident. Homes let out or occupied by someone as their main home are not normally treated as second homes for this premium.

The direction of travel is clear: second homes, empty homes and non-resident-owned homes are likely to remain politically visible. Owners should model higher annual holding costs, not just purchase costs and maintenance.

Renters may not pay property tax directly, but they can still be affected. If a future system shifts legal responsibility from occupiers to owners, tenants may no longer receive the bill directly. But that does not mean renters are unaffected.

Landlords may try to recover higher costs through rents where the market allows. In other cases, higher recurring property costs could affect property prices, rental yields, landlord behaviour and the supply of rental homes.

For renters planning to buy, the key question is whether lower upfront transaction costs are offset by higher annual ownership costs.

But lower stamp duty does not automatically mean buying becomes easier. Sellers may capture some of the benefit through higher prices, and any annual property charge would become part of the buyer's long-term affordability calculation.

First-time buyers should model both the upfront cost and the recurring annual cost. A lower purchase tax can help with the deposit and completion stage, but a higher annual property charge affects affordability every year.

For people moving because of children, schools, work, divorce, separation or caring responsibilities, stamp duty can be a major friction. Replacing some stamp duty with an annual charge could make moving easier.

The impact depends heavily on the property value and how long the household expects to stay. A family upsizing from a £350,000 home to a £650,000 home may save upfront tax under some reform models, but pay a higher annual property tax thereafter.

A household planning to move again in five years may prefer lower transaction taxes. A household expecting to stay for twenty-five years may care more about recurring annual charges.

For established homeowners, the key risk is complacency. A property that feels ordinary locally may still be high-value nationally. Under a proportional system, the bill is driven by current property value, not by an old council tax band.

Households in London, the South East and expensive commuter areas could be more exposed than households with similar incomes in lower-value regions.

The planning question is simple: what would happen if annual property costs rose by £500, £1,000, £2,000 or more? That matters for mortgage affordability, school fees, care responsibilities, retirement saving, emergency funds and decisions about whether to move.

Retirees are central to this debate. Many older homeowners have valuable homes but modest taxable income. A higher annual property charge could create a cashflow problem even where net wealth is high.

That is why some reform proposals include deferral mechanisms. Deferral means the tax is not paid immediately but is instead rolled up and paid later, often on sale or death. This protects short-term cashflow but reduces future estate value.

For retirees, property tax reform should be modelled alongside pension withdrawals, State Pension income, investment income, care costs, inheritance plans and downsizing choices.

Downsizers could be winners or losers depending on the design. If stamp duty is reduced, moving to a smaller or more suitable home could become easier. That could help people release equity, reduce maintenance costs and move closer to family.

But if a new annual charge is based on property value, downsizers need to compare the ongoing cost of the old home and the new home, not just the one-off transaction cost.

The important question is not only how much tax is saved when moving. It is how the move changes lifetime cashflow, housing costs and final estate value.

Second-home owners are already under more scrutiny. Councils in England can apply up to a 100% council tax premium on second homes from April 2025, and some proportional property tax proposals suggest higher annual rates for second homes.

A second home worth £400,000 would face an illustrative annual charge of £3,840 at 0.96%. A £750,000 second home would face £7,200. That would sit alongside maintenance, insurance, mortgage costs, utilities and any local restrictions or licensing rules.

For second-home owners, the financial planning question is blunt: does the property still work if annual ownership costs rise materially?

Landlords are affected on several fronts. Buying an additional residential property in England or Northern Ireland usually attracts the SDLT surcharge on top of standard rates. Source: https://www.gov.uk/stamp-duty-land-tax/residential-property-rates

Some reform proposals would shift property tax responsibility from occupiers to owners. That would make the landlord's cashflow model more explicit: rent received, mortgage costs, maintenance, insurance, agent fees, income tax, potential capital gains tax and annual property tax.

A higher recurring property tax could affect yields, rent-setting, portfolio decisions and selling decisions. Some landlords may absorb the cost, some may try to increase rents, and some may sell lower-yielding properties.

Landlords should model property tax reform per property, not just at portfolio level. A low-yield property in a high-value area may be affected very differently from a higher-yield property in a lower-value area.

Non-resident ownership is also in scope. Current SDLT rules usually add a surcharge for non-UK residents buying residential property in England or Northern Ireland. Source: https://www.gov.uk/stamp-duty-land-tax/residential-property-rates

Some reform proposals suggest higher recurring annual rates for non-resident-owned homes, while other proposals focus on increasing purchase surcharges.

For non-resident owners, the risk is that both purchase taxes and annual holding taxes rise.

Do not build a financial plan around one assumed political outcome. Build scenarios.

Useful scenarios include current rules, council tax band reform, proportional property tax, higher-rate models for second homes and non-resident owners, stamp duty replacement, and deferral models for asset-rich but cash-poor households.

The practical calculation is straightforward. Annual property tax equals property value multiplied by the tax rate. Net annual impact equals the new annual property tax minus current council tax. Cumulative impact depends on how long the property is held, how property values grow, and whether the tax rate is fixed or changes over time.

For moving decisions, compare current council tax plus stamp duty on purchase with a reform scenario that may involve lower upfront tax but higher recurring annual property tax.

Property tax reform is not yet settled policy, but the direction of travel is clear enough to plan around.

Council tax is widely viewed as outdated. Stamp duty is widely criticised for discouraging movement. Higher-value homes, second homes, empty homes, landlords and non-resident owners are increasingly visible targets.

At the same time, any major reform would need transition rules, local government funding rules, valuation rules and protections for asset-rich but cash-poor households.

The right response is not to assume the worst. It is to understand your exposure. If you own property, ask what your current council tax is, what your property is realistically worth, what a 0.4%, 0.5% or 1.0% annual property charge would mean for cashflow, and whether that would change your decision to buy, sell, downsize, let, keep or pass on property.

For many households, the impact may be manageable. For others, especially high-value homeowners, second-home owners and landlords with tight cashflow, the numbers could be material.

Planiva helps you compare scenarios before making long-term financial decisions. Property tax reform is exactly the kind of uncertainty that should be modelled, not guessed.
