If you’re trying to decide where to put your money, the property versus stocks debate in the UK often comes down to a single number that most people get wrong. Since 30 October 2024, capital gains tax (CGT) on both asset classes has been charged at the same rates — 18% and 24%. The old assumption that shares are taxed more lightly on gains no longer holds. What actually separates the two is everything else: how income is taxed, what you can deduct, the entry costs, and — most importantly — whether you can hold the investment inside a tax wrapper like an ISA or a pension.

Property has historically returned around 8% a year when you add rent and capital growth together, while UK stocks have delivered roughly 7–9% annually over the long run. Those headline numbers look similar, but the net amount you keep after tax, costs, and management differs dramatically depending on how you invest. The wrapper you use — or don’t use — matters more than the asset class itself. Here’s what you actually need to know.
Four Things That Actually Separate Property and Stocks
The central concept that ties all of this together is the tax wrapper.
What I tend to notice is that most comparisons skip straight to historical returns without asking the question that actually changes the outcome: how much of that return will you keep after tax and costs? The wrapper answer usually decides it.
Rates, Thresholds, and What They Actually Cost You
The tax treatment of property income is about to change. From 6 April 2027, rental profit will be taxed at separate rates of 22% (basic rate), 42% (higher rate), and 47% (additional rate) under the Finance Act 2026. For the 2026/27 tax year, rental income is still taxed at your marginal income tax rates — 20%, 40%, or 45% — with mortgage interest restricted under Section 24 to a basic-rate tax credit of 20% (rising to 22% from 2027).
Dividends from shares are taxed on a separate scale: 10.75% for basic-rate taxpayers, 35.75% for higher-rate, and 39.35% for additional-rate, with a £500 dividend allowance. Interest from bonds and savings is taxed at your marginal income tax rates, softened by the personal savings allowance (£1,000 for basic-rate, £500 for higher-rate, nil for additional-rate).
Here is how the two asset classes compare on the key tax and cost metrics:

| Factor | Direct Property | Shares (outside ISA) | Shares (inside ISA) |
|---|---|---|---|
| Income tax rate | Marginal rates (20/40/45%) until Apr 2027, then 22/42/47% | Dividend rates (10.75/35.75/39.35%) | 0% |
| CGT rate | 18% / 24% | 18% / 24% | 0% |
| Annual allowance | £3,000 CGT exempt amount | £3,000 CGT exempt amount | No limit on gains |
| Purchase cost | SDLT + 5% surcharge (up to ~15% total) | 0.5% SDRT | 0.5% SDRT |
| Mortgage interest relief | Restricted to 20% tax credit (22% from 2027) | N/A | N/A |
Take a higher-rate taxpayer earning £60,000 who owns a rental property with £15,000 in annual rent and £10,000 in mortgage interest. Under Section 24, they cannot deduct that £10,000 interest. Instead they pay tax on the full £15,000 at 40% — £6,000 — then receive a 20% tax credit of £2,000, leaving a net tax bill of £4,000. Their actual rental profit after tax is £1,000 on £15,000 of rent. The same £15,000 in dividends outside an ISA would be taxed at 35.75% on the amount above the £500 allowance, leaving roughly £9,800 after tax. Inside an ISA, the full £15,000 is tax-free.
Where People Get This Wrong
The CGT rate myth that refuses to die
Many investors still believe property gains are taxed more heavily than share gains. That stopped being true on 30 October 2024. Both are now charged at 18% and 24%. The real difference is that shares can be held inside an ISA where CGT doesn’t apply at all, while property gains always face the tax. If you’re comparing gains outside a wrapper, the rates are identical — the old argument no longer holds.
Ignoring Section 24 when calculating rental returns
The most common mistake I see is someone running the numbers on a buy-to-let using gross rent minus mortgage interest, then concluding the yield looks attractive. Section 24 means that for a higher-rate taxpayer, every £1 of mortgage interest effectively costs 40p in lost tax relief compared to the old system. A property yielding 5% gross can easily become 2% or less after tax for a geared landlord. The fix is to run the calculation using the tax-credit method, not the old deduction method. If the numbers don’t work under Section 24, they don’t work.
Overlooking the entry cost gap
Buying a £200,000 second property in England means stamp duty of £1,500 on the first £250,000 (0% up to £250,000 for residential, but the 5% surcharge applies on the full amount) — actually, let me be precise: for a £200,000 second home, SDLT is 0% on the first £250,000, but the 5% surcharge adds £10,000, plus 5% on the portion above £250,000 if applicable. For a £200,000 property, that’s £10,000 in surcharge alone, plus legal fees and survey costs. Buying £200,000 in shares costs £1,000 in Stamp Duty Reserve Tax and a few pounds in broker fees. That £9,000 difference is money that never gets invested.
Forgetting that property is in your IHT estate
UK residential property is within your estate for inheritance tax purposes. For non-domiciled investors, the non-dom regime was abolished from 6 April 2025, meaning worldwide assets including UK property are now within the IHT net. Shares held in an ISA or pension are generally outside your estate for IHT, or benefit from different treatment. This is a long-term cost that many people don’t factor into their decision.
How to Actually Compare Property and Stocks for Your Situation
Start with the wrapper question
If you have ISA or pension allowance available, shares inside those wrappers have a structural tax advantage that property cannot match. The £20,000 annual ISA allowance means you can shelter a significant amount of share investments from income tax and CGT entirely. Property cannot go inside an ISA. If you haven’t used your full ISA allowance, the first question to ask is whether you’re better off maxing that out before considering direct property. For many people, the answer is yes.
Run the Section 24 calculation for geared property
If you’re considering a buy-to-let with a mortgage, you need to calculate your net return after the Section 24 restriction. Take your gross rent, deduct allowable expenses (not mortgage interest), apply your marginal tax rate, then add back the 20% tax credit on the interest. What’s left is your actual profit. For a higher-rate taxpayer with significant borrowing, the net yield can be less than 2%. At that point, even a basic savings account may outperform property on a risk-adjusted basis.
Consider incorporation for serious property investors
Holding property through a limited company changes the tax treatment of finance costs — mortgage interest becomes a deductible expense rather than a restricted tax credit. Corporation tax rates (19–25%) are lower than higher-rate income tax. But incorporation comes with its own costs: annual filing, potential CGT on transferring property into the company, and higher tax on extracting profits. This route makes sense only if you’re building a portfolio large enough to justify the overhead. For a single property, it rarely works out.
Factor in the operational burden
Property requires tenant management, maintenance, compliance with rental regulations, insurance, and — if your gross rents cross the threshold — Making Tax Digital for income tax. Shares require none of that. The time cost of managing a property is real, and it reduces your effective hourly return. If you value your time, that tilts the scales toward stocks, especially if you use low-cost index funds.
Upcoming rule changes to watch
From 6 April 2027, property income will be taxed at the new separate rates of 22%, 42%, and 47%, and the Section 24 tax credit rises to 22%. That slightly improves the position for basic-rate landlords but doesn’t change the fundamental disadvantage for higher-rate taxpayers. No equivalent change is on the horizon for share taxation. If you’re planning a property purchase, run your numbers under both the current and 2027 rules to see how much the shift affects you.

The Wrapper Decides More Than the Asset
The single most consequential difference between property and stocks isn’t historical returns or even the CGT rate — it’s whether the investment can sit inside a tax wrapper. Shares inside an ISA or pension grow free of income tax, dividend tax, and CGT. Property cannot. That structural advantage compounds over time and, for most investors, makes stocks the more tax-efficient choice unless you have specific reasons to prefer property — like the ability to use leverage or the desire for a tangible asset you can control. Run the numbers on your own tax position before you decide, because the wrapper question changes the answer for every income level.
