A BTL investor pays £25,000 in stamp duty on a £350,000 acquisition. A home mover pays £7,500. A first-time buyer pays £2,500. That £17,500 to £22,500 gap is not recoverable from rental income within any sensible holding period at current rates.
What Has Happened?
The Resolution Foundation, a UK economic research organisation, published a report this week calling England's two main housing taxes "badly designed" and arguing that they should both be abolished. Stamp duty land tax and council tax, the think tank says, increase regional inequality, suppress labour mobility and block an estimated 100,000 home purchases every year.
The central finding on regional inequality: Londoners collectively under-pay property tax by £3.1 billion a year compared to what a proportional system would charge. Around 80% of London households benefit from this. In the North East, 85% of households are over-paying by comparison. The analysis used 2024-25 data.
The distortion comes from how both taxes were designed. Council tax bands still use property valuations from 1991. The gap between London values and northern values has widened so dramatically in the 35 years since then that Band D in Hampstead is effectively taxed at a tiny fraction of the rate, relative to property value, that Band D in Sunderland or Hartlepool is. By the end of this decade, under the current system, someone in a home worth £100,000 will pay nearly three times more property tax relative to their property's value than someone in a £1 million home.
On stamp duty: the Foundation estimates the tax prevents around 100,000 home purchases per year, because the transaction cost deters natural downsizers, people relocating for work, and households at life stages where a move would otherwise be logical. It is not a tax on wealth in any proportional sense. It taxes the decision to move, and it does so in a way that compounds the existing rigidity in housing supply.
Residential property sales in England and Wales fell 18.4% in the year to March 2026 compared to the previous year. That compares a period including the SDLT deadline rush of March 2025, when buyers completed at elevated rates, against the quieter period that followed the threshold change. The drop is across all buyer types. For buy-to-let specifically, the investor share of purchases fell to 10.8% in 2026, the lowest since tracking began, down from an 11.8% average over the preceding decade.
The proposed reform is a single annual levy set at 0.7% of a property's current market value, replacing both stamp duty and council tax, designed to be revenue-neutral overall. A rebate for lower-income households is included. No legislative timetable is attached to the proposal, and the government has made no commitment to adopt it. The report explicitly calls on ministers to act in the autumn statement cycle.
Why This Matters to UK Property Investors
The most immediate number is the acquisition cost differential. A BTL investor buying at £350,000 in England today pays approximately £25,000 in stamp duty under the current rules. The equivalent home mover on the same property pays £7,500. A first-time buyer pays £2,500. That gap of £17,500 to £22,500 between the investor's bill and other buyer types is not recovering from rental income within a sensible holding period. On a 7% gross yield at £350,000, annual gross rent is £24,500. The stamp duty alone costs roughly one full year of gross income before you have even started letting.
On a £200,000 acquisition, the BTL stamp duty bill runs to approximately £11,000. On a £150,000 property in the North East, it is around £7,500. The surcharge was raised from 3% to 5% in October 2024, adding roughly £7,000 to the cost of a £350,000 purchase overnight. The higher the surcharge, the more pronounced the effect on shorter-term strategies.
The regional inequality finding is directly relevant to northern BTL investors, and not in the way most people assume. The report shows that northern buyers, in markets where property values are already lower, are proportionally over-taxed under the current council tax framework relative to the actual value of what they own. The 5% BTL surcharge compounds an existing unfairness. The combined effect of proportional under-valuation in council tax bands and a flat-rate stamp duty surcharge means the total tax burden on a northern BTL acquisition is higher relative to its value than the equivalent London investment. Not lower. Higher.
The 100,000 blocked moves finding matters for demand analysis. People who cannot afford to move because of stamp duty are also people who are not selling. Owner-occupied stock that would otherwise release into the market stays put. In areas with high owner-occupier concentrations and limited new build, the rental market absorbs demand from households that in an earlier era would have bought. The tenant pool is structurally broader than it would be in a lower-friction transaction environment.
The Risks Investors Need to Understand
The Resolution Foundation's report is a think-tank recommendation. It has no legislative timetable. The government has not committed to any element of it, and there is no autumn statement confirmation that property tax reform is being considered in this form. I would not make an acquisition or disposal decision based on stamp duty abolition happening on any particular schedule. Think-tank proposals for property tax reform have been circulating since 2009. Council tax revaluation has been raised by successive governments since the 1990s and has never happened. The fiscal and political costs of transition are substantial.
The more immediate risk for investors runs in the opposite direction: the October autumn statement could go further in the current direction, not reverse it. CGT treatment of property disposals remains a live policy discussion. Any holding-period model built on exit in under five years needs to price in the full 5% BTL stamp duty on entry, the legal and sourcing costs, and exit costs including a CGT calculation at current or higher rates. If the exit return only works if rates stay where they are, or if SDLT comes off, that is a bet on the policy cycle, not an income-led investment.
The 18.4% sales drop in the year to March 2026 affects lender valuations. In thinner markets, surveyors apply down-valuations more frequently because comparable evidence is sparse. If you are buying at 75% LTV and the lender's valuer comes in 5% below the agreed purchase price, you make up the difference in cash or renegotiate. Cash buyers and investors financing at 60% to 65% LTV are insulated from this. Mortgaged investors at 75% are not.
There is also a timing asymmetry with the proposed 0.7% annual levy. An investor who buys a £250,000 property today and holds it for 20 years would pay cumulative annual levies of £35,000 under the proposed system, assuming static property values. If property values rise to £350,000 over that period, cumulative levies run to £49,000, well above what stamp duty would have cost on entry. The new system would be better for short-hold strategies and worse for very long holds on appreciating assets. That is not a reason to oppose the proposal. It is a reason to model carefully what it means for specific portfolio positions.
Where the Opportunity Could Be
The 100,000 blocked moves have a specific consequence for acquisition strategy. A significant share of owner-occupied stock that would move in a lower-friction environment is sitting inert because the SDLT cost makes the economics of downsizing or upsizing poor. That means in areas with high owner-occupier concentrations, supply that would normally circulate through the sales market is delayed or absent. The consequence for landlords in those areas is that tenant demand is drawing from households that, in an earlier period, would have bought. That is structural support for rental demand that does not depend on any single economic cycle.
The stamp duty cost on cheaper northern stock is lower in absolute terms. A £100,000 property in Sunderland attracts approximately £3,000 in BTL stamp duty (5% surcharge applies on the full purchase price above the nil-rate threshold). That represents 3% of the acquisition price. On a £350,000 southern property, the £25,000 cost represents 7.1%. The proportional burden is lighter on lower-value acquisitions. For investors focused on sub-£150,000 stock in high-demand rental markets like Sunderland SR4, Middlesbrough TS1, or Hartlepool TS24, the acquisition tax cost is real but manageable.
If reform ever comes, properties acquired today under the current stamp-duty regime carry a sunk cost that will not recur under the new system. An investor who bought a £200,000 North East property and paid £11,000 in BTL stamp duty would, under the 0.7% annual levy, pay £1,400 per year going forward. After the 8 years needed to match the sunk cost in annual terms, the regime becomes cheaper. For income-focused investors with long holding periods, a switch to annual levies favours properties already acquired.
The 10.8% investor share of purchases in 2026 is the lowest on record. Fewer investors competing for properties means less competitive bidding at auction, fewer competing offers on private sales, and more motivated vendor supply from landlords choosing to exit rather than expand. For investors who remain in the market and can move with speed and certainty, the pool of competing buyers is smaller than it has been in a decade.
Arsh's Investor View
I will be direct: I am not expecting stamp duty abolition at the October autumn statement. Think tanks have been making this case, in various forms, for fifteen years. The arguments are correct. The council tax band system based on 1991 valuations is, frankly, one of the more absurd structural features of the UK property market. Wealthier Londoners are under-taxed relative to their asset values, and northern homeowners are over-taxed relative to theirs. That is not a minor technical issue. It is a chronic misallocation built into every council tax bill in the country.
But the political and fiscal cost of transition is enormous. Every winner creates a loser. The 80% of Londoners who currently benefit from under-payment would lose. They vote in disproportionate numbers and are well-organised. No government has managed council tax revaluation in 35 years. It is not going to happen in a single autumn statement.
The 100,000 blocked moves figure is the data point worth keeping. Not as a reform argument, but as context for the current acquisition environment. The transaction market is suppressed. That suppression is partly cyclical and partly structural. The structural component, the SDLT barrier to natural movers, is not going away in the short term. A market where 100,000 fewer transactions happen each year than would otherwise is a market where motivated vendor supply concentrates among the sellers who need to move regardless of the tax cost. Landlords exiting under regulatory pressure are in that category. They are not selling because the SDLT economics of the buyer are favourable. They are selling because their own circumstances require it.
On the BTL surcharge: at 5%, it costs me £25,000 to buy a £350,000 property. That is a real cost and it shapes which deals are worth doing. But it also means many other investors have simply stopped looking. The investor share of purchases is at a record low. A record-low buyer pool means fewer competing offers on properties I want to acquire. The same policy that costs me £25,000 on entry has cleared out a portion of my competition. I can live with that trade-off on an income-positive acquisition at the right price.

Key Takeaways
- Resolution Foundation's September 2026 report: stamp duty prevents an estimated 100,000 home purchases per year, by deterring natural movers, downsizers, and people relocating for work. The 100,000 figure is a structural drag on transaction volumes, not a cyclical one.
- Londoners collectively under-pay property tax by £3.1 billion a year relative to a proportional system. 85% of North East households over-pay by the same measure. Council tax still uses 1991 property valuations. By the end of this decade, someone in a £100,000 home will pay nearly three times more property tax relative to value than someone in a £1 million home.
- A BTL investor pays approximately £25,000 in stamp duty on a £350,000 acquisition in England. A home mover pays £7,500. A first-time buyer pays £2,500. The gap represents roughly 12 months of gross rental income on a 7% yield property and is the highest-priority acquisition cost for any yield model.
- Residential property sales in England and Wales fell 18.4% in the year to March 2026 following the SDLT threshold change in April 2025. BTL investors' share of purchases fell to a record-low 10.8% in 2026, down from an 11.8% average over the preceding decade. Fewer competing buyers means less competitive bidding for investors who remain active.
- The proposed reform, a 0.7% annual levy on current property values replacing both stamp duty and council tax, is revenue-neutral. It has no confirmed legislative timetable and no autumn statement commitment. No acquisition or disposal decision should be predicated on its implementation on any specific schedule.
Frequently Asked Questions
What did the Resolution Foundation say about stamp duty in September 2026?
The Resolution Foundation published a report in September 2026 arguing that stamp duty land tax and council tax are both badly designed and should be abolished together. The think tank estimated stamp duty prevents around 100,000 home purchases per year by deterring people from moving for work, downsizing, or upsizing. The report found Londoners collectively under-pay property tax by £3.1 billion a year compared to a proportional system, while 85% of households in the North East over-pay. The think tank proposed replacing both taxes with a single 0.7% annual levy on current property values, designed to be revenue-neutral, with rebates for lower-income households.
How much stamp duty does a buy-to-let investor pay in England in 2026?
Under the rules effective from October 2024, a BTL investor in England pays a 5% second-property surcharge on top of standard SDLT rates. On a £350,000 acquisition, total stamp duty comes to approximately £25,000, compared with £7,500 for a home mover and £2,500 for a first-time buyer on the same property. On a £200,000 investment property, the total BTL stamp duty bill is approximately £11,000. On a £150,000 North East property, it is around £7,500. The surcharge was raised from 3% to 5% in the October 2024 Autumn Statement.
Would abolishing stamp duty benefit buy-to-let investors?
Abolishing the BTL surcharge would transform the economics of higher-frequency acquisition strategies and shorter-hold approaches. The proposed 0.7% annual levy replacement would cost £1,750 per year on a £250,000 property, compared with an upfront stamp duty bill of roughly £12,500 on that same acquisition today. For income investors holding for 7 years or more, the cumulative annual levy would eventually exceed the sunk stamp duty cost. For investors buying and holding for income, the annual levy is a lower friction point than a large upfront acquisition cost. Reform would benefit shorter-hold strategies more directly than long-hold income portfolios.
What happened to UK property sales after the stamp duty change in April 2025?
Residential property sales in England and Wales fell 18.4% in the year to March 2026 compared to the previous year. That comparison spans the rush of completions in March 2025 before the SDLT threshold changed and the significantly quieter period that followed. The impact was broadly distributed across all buyer types. BTL investors' share of total purchases fell to 10.8% in 2026, the lowest on record and below the 11.8% average over the preceding decade. Volume recovery through the second half of 2026 has been partial, with sales still below pre-threshold-change levels in most regions.
What is the regional inequality in UK property tax the Resolution Foundation identified?
The Resolution Foundation's September 2026 report found that London households collectively pay £3.1 billion less in property tax each year than a proportional system would charge. Around 80% of London households benefit from this. In the North East, 85% of households are over-paying relative to what their property values would attract under a proportional system. The distortion originates from council tax bands still calculated using 1991 property valuations, when the price gap between London and the north was far narrower. By the end of this decade, a household in a £100,000 property will pay nearly three times more property tax relative to their property's value than a household in a £1 million home.
