Property Investment vs Stocks and Shares: The UK Tax Comparison for 2026/27

If you are a UK landlord or investor, the question of whether your money works harder in buy-to-let bricks and mortar or in a portfolio of stocks and shares often comes down to tax. The honest answer is that the comparison has changed, and a lot of what you will read online is now out of date. The single biggest myth is that shares enjoy a lower capital gains tax rate than property. That stopped being true on 30 October 2024. Since then, all individual gains, on property and on shares alike, are charged at the same 18% and 24% rates.

So if capital gains tax no longer separates the two, what actually does? Three things: the availability of a tax wrapper (the ISA and the pension), how the income is taxed (rental profit versus dividends, and the separate property income rates that arrive on 6 April 2027), and the Section 24 finance-cost restriction that hits geared individual landlords and has no equivalent for shares. This guide works through each of those, with current 2026/27 figures and worked examples, and explains where a third option, incorporation, fits in.

Property vs shares: the side-by-side tax comparison

The table below sets out how the two asset classes are taxed in 2026/27, including the third route most people overlook: shares held inside an ISA or pension, which is the closest thing to a tax shelter that exists for any kind of investment.

Tax feature	Direct buy-to-let property	Shares held directly	Shares in an ISA or pension
Income tax on income	Rental profit at marginal rates (separate 22%/42%/47% property rates from 6 Apr 2027)	Dividends at 10.75%/35.75%/39.35%, GBP500 allowance	Tax-free
Capital gains tax on disposal	18% / 24% (TCGA 1992 s.1H)	18% / 24% (same rates since 30 Oct 2024)	Tax-free
Annual CGT exempt amount	GBP3,000	GBP3,000	Not needed (no CGT)
Relief for borrowing costs	Restricted to a 20% basic-rate reducer (Section 24)	Generally none for individuals	Generally none for individuals
Tax wrapper available	None for direct property	None outside ISA/pension	ISA up to GBP20,000/yr; pension within limits
Entry tax on purchase	SDLT plus 5% additional-dwelling surcharge (LBTT+ADS in Scotland, LTT in Wales)	0.5% Stamp Duty Reserve Tax on UK shares	0.5% SDRT on UK shares (gains still sheltered)
CGT reporting deadline	60-day report and payment on residential disposal	Self Assessment	No reporting (no CGT)
Making Tax Digital	Yes, once gross rents cross the threshold	No (passive share income is not qualifying)	No

Read that table carefully and one conclusion jumps out: the wrapper, not the capital gains tax rate, is what separates the two on a pure tax basis. Below we explain each row.

How is rental income from property taxed?

Rental income from a buy-to-let is taxed as property income. For the 2026/27 tax year it is added to your other income and taxed at your marginal rate of 20% (basic), 40% (higher) or 45% (additional). You can deduct genuine running costs such as letting agent fees, repairs, insurance, service charges and ground rent before arriving at your taxable profit. Mortgage interest is the major exception, because Section 24 turns it into a basic-rate reducer rather than a deduction, which we cover below. For the full list of what you can and cannot deduct, see our guide to landlord tax deductions for 2026.

A significant change is already law, not a proposal. From 6 April 2027, property income is taxed at separate rates of 22% (basic), 42% (higher) and 47% (additional) under sections 6 and 7 of the Finance Act 2026, which received Royal Assent on 18 March 2026. These rates apply in England, Wales and Northern Ireland (Scotland sets its own non-savings, non-dividend rates). To keep the maths consistent, the Section 24 reducer rises from 20% to 22% in step, so no new basic-rate wedge opens for geared landlords. The practical effect is that, for individuals, property income stops being simply blended with salary and other earnings. We explain the mechanics in detail in our guide to the 2027 property income tax rates for landlords.

How is income from shares taxed?

Income from shares usually arrives as dividends. For 2026/27, dividends are taxed on their own scale at 10.75% (basic), 35.75% (higher) and 39.35% (additional), with a GBP500 dividend allowance that taxes the first GBP500 of dividends at 0%. Interest from bonds and savings is taxed at your marginal income tax rate, softened by the personal savings allowance (GBP1,000 for basic-rate taxpayers, GBP500 for higher-rate, nil for additional-rate).

The decisive feature is the wrapper. Investments held inside a Stocks and Shares ISA are entirely free of income tax and capital gains tax, and you can contribute up to GBP20,000 each tax year. Pensions add a second tax-advantaged home for shares, with relief on the way in. There is no equivalent shelter for a buy-to-let you own directly. This is why, for the passive portion of a portfolio, wrapped shares are usually the more tax-efficient choice, even now that the capital gains tax rates have converged.

Capital gains tax: the myth that property is taxed more heavily than shares

This is the section that most online comparisons get wrong, so it is worth being precise. Capital gains tax is charged on the profit (the gain), not the sale proceeds, when you dispose of an asset. Under section 1H of the Taxation of Chargeable Gains Act 1992, headed "The main rates of CGT", all individual chargeable gains are charged at 18% to the extent of any unused basic-rate band and 24% above it. Section 1I then decides how much of the gain falls at each rate by reference to your unused basic-rate band.

The key word is "all". The old 10% and 20% rates that used to apply to shares and other non-residential assets were abolished at the Autumn Budget 2024, with effect from 30 October 2024. Since then there has been no capital gains tax rate gap between selling a rental property and selling a share portfolio. Both are at 18% and 24%, and both enjoy the same GBP3,000 annual exempt amount for 2025/26 and 2026/27. For the property side in full, see our current CGT rates explainer and the broader capital gains tax on property guide.

Two genuine differences survive on the capital gains side. First, reporting: a UK residential property disposal must be reported and the tax paid within 60 days, whereas share gains are dealt with through Self Assessment. Second, and far more important, the ISA shelter: gains on shares inside an ISA or pension are tax-free, so a wrapped share investor pays no capital gains tax at all, while a direct property owner always faces the charge on a gain above the annual exempt amount. The capital gains advantage of shares is therefore real, but it comes entirely from the wrapper, not from a lower headline rate.

Allowances and reliefs: a true side-by-side

Each asset class has reliefs the other lacks. Property has Private Residence Relief under section 222 of the Taxation of Chargeable Gains Act 1992, which removes capital gains tax on the sale of your main home, including a part-let or formerly let home for qualifying periods. There is no shares analogue. See our guide to Private Residence Relief for landlords for how this interacts with letting.

Shares have the wrapper. The ISA allowance shelters up to GBP20,000 a year of contributions, with both income and gains free of tax for as long as the investments stay inside. Pension contributions add tax relief on the way in. Both spouses can also use no-gain, no-loss transfers between themselves to spread gains across two annual exempt amounts and two sets of basic-rate band, a planning lever that works for property and shares alike. The GBP3,000 annual exempt amount applies equally to both asset classes.

Section 24: the real reason geared property carries a higher tax cost

Section 24 of the Finance (No. 2) Act 2015, headed "Relief for finance costs related to residential property businesses", changed how individual landlords get relief for mortgage interest. You can no longer deduct the interest from rental income. Instead, you receive a basic-rate tax reducer worth 20% of the finance costs (rising to 22% from 2027/28 to match the new property basic rate). For a higher-rate or additional-rate landlord this pushes up the effective tax rate on geared property, and in tightly geared cases can tax you on more than your true economic profit. Our Section 24 mortgage-interest restriction guide walks through the mechanics, and our practical guide to claiming mortgage interest relief shows how the reducer is applied on a tax return.

There is no Section 24 for shares. An individual buying shares with borrowed money generally gets no relief for the interest at all, which is one reason most share investors simply do not gear and instead hold ungeared positions inside an ISA or pension. The upshot is important for the comparison: where people say "property is less tax-efficient than shares", the truth is that geared property held personally is less tax-efficient because of Section 24, not because of any capital gains tax difference.

The third option: holding property through a limited company

Section 24 does not apply to companies, so many landlords now hold portfolios through a limited company that deducts mortgage interest in full against rental profit. The company pays corporation tax at 19% on profits up to GBP50,000, 25% on profits above GBP250,000, and an effective 26.5% on the slice between those thresholds. That can compare favourably with a 40% or 45% individual marginal rate on geared rental income.

The catch is the second layer of tax. Extracting profit from the company as dividends is taxed again in your hands at the dividend rates above, and transferring existing personally held property into a company can crystallise capital gains tax and stamp duty land tax on the way in. Whether incorporation wins depends on gearing, your marginal rate, and whether you need to draw the income or can leave it to roll up. We compare the personal and company routes in our tax-efficient property structure guide and set out the company route in full in the buy-to-let limited company guide. Crucially, incorporation changes how you hold property; it does not give property the ISA-style wrapper that shares enjoy.

Entry costs: stamp duty on property versus shares

The tax cost of getting in differs sharply. Buying an additional residential property (which a buy-to-let almost always is) attracts stamp duty land tax plus the 5% additional-dwelling surcharge in England and Northern Ireland. Scotland charges Land and Buildings Transaction Tax with the Additional Dwelling Supplement, and Wales charges Land Transaction Tax with its own higher residential rates. Buying most UK shares electronically attracts Stamp Duty Reserve Tax at 0.5%, with no additional-dwelling style surcharge. For a meaningful portfolio, the entry tax on property is many times higher than on shares, and that drag has to be earned back before property pulls ahead.

Making Tax Digital: who has to comply?

Making Tax Digital for Income Tax is now live and phasing in by income level. It applies to self-employment and property income, not to passive investment income from shares. Dividends and savings interest are not qualifying income, so a pure share investor has no MTD obligation on that income. Landlords are brought in by gross property income: from 6 April 2026 at GBP50,000, from 6 April 2027 at GBP30,000, and from 6 April 2028 at GBP20,000. Once you cross your threshold you must keep digital records and file quarterly updates. Our MTD for landlords guide sets out exactly what changes and when.

Worked example 1: a higher-rate geared landlord

Take a higher-rate taxpayer with a buy-to-let producing GBP20,000 of rent and GBP10,000 of mortgage interest, with GBP3,000 of other deductible running costs. Under Section 24, the interest is not deducted, so the taxable property profit is GBP17,000 (rent less the GBP3,000 of non-finance costs). Tax at 40% is GBP6,800, reduced by the basic-rate finance-cost reducer of 20% of GBP10,000, which is GBP2,000. The income tax bill is therefore GBP4,800 on a real cash profit of GBP7,000 (GBP20,000 less GBP10,000 interest less GBP3,000 costs), an effective rate of roughly 69% on the cash actually earned. That high effective rate is the Section 24 effect, and it is the strongest tax argument against holding geared property personally.

Worked example 2: the same money in dividends, inside and outside an ISA

Now take an investor with GBP20,000 of dividend income from shares. Outside any wrapper, after the GBP500 dividend allowance, GBP19,500 is taxable; at the higher dividend rate of 35.75% the tax is about GBP6,971. Hold exactly the same shares inside a Stocks and Shares ISA and the tax is nil. The contrast is the whole point: the share investor can legally remove the entire income tax charge using a wrapper, whereas the landlord above cannot shelter rental income at all. This is the wrapper advantage doing the heavy lifting, not a capital gains rate difference.

Worked example 3: selling up, where the rates are now equal

Suppose each investor realises a GBP50,000 gain and is a higher-rate taxpayer. On the rental property, after the GBP3,000 annual exempt amount, GBP47,000 is taxed at 24%, giving GBP11,280, reportable and payable within 60 days. On directly held shares, the same GBP47,000 is taxed at the same 24%, giving the same GBP11,280, reported through Self Assessment. If those shares were inside an ISA, the capital gains tax is nil. The disposal stage confirms the headline: the rates are identical, and the only capital gains advantage shares hold is the ISA shelter. For the property-side calculation in detail, see our guide to working out CGT on a buy-to-let sale.

So which is more tax-efficient?

For the passive part of a portfolio, wrapped shares win on tax. The ISA and pension shelter income and gains entirely, there is no Section 24, no 60-day reporting, and no additional-dwelling surcharge on entry. For a buy-to-let you own directly, none of that shelter exists, and if you gear the property personally, Section 24 raises the effective tax rate further.

Property's counter-arguments are about return and control rather than tax. Leverage lets you control a large, inflation-linked asset with a fraction of the capital, you can add value through refurbishment or planning, and rents tend to rise with inflation. A geared property can therefore out-earn wrapped shares on total return despite a higher tax cost, but that is a return argument, not a tax-efficiency one. For higher-rate landlords, incorporation can narrow the tax gap by restoring full interest relief, at the cost of a second layer of tax on extraction. For the wider landlord-tax picture, see our property investment tax guide for 2026.

Key takeaways

• Capital gains tax is now the same for both: 18% and 24% for property and shares alike since 30 October 2024 (TCGA 1992 s.1H). The old 10%/20% shares rates are gone.
• The real tax difference is the wrapper. Shares can sit in an ISA (GBP20,000/yr) or pension, free of income tax and capital gains tax; direct buy-to-let has no equivalent shelter.
• Rental income is taxed at marginal rates now, and at separate property rates of 22%/42%/47% from 6 April 2027 (Finance Act 2026 ss.6-7, enacted, applying in England, Wales and Northern Ireland).
• Section 24 restricts mortgage-interest relief for individual landlords to a basic-rate reducer (20%, rising to 22% from 2027/28); shares have no such restriction.
• Holding property through a company avoids Section 24 but adds a second layer of tax on extraction and can trigger CGT and SDLT on the way in.
• Property carries higher entry tax (SDLT plus the 5% additional-dwelling surcharge) and a 60-day CGT reporting deadline that shares do not.

The right answer depends on whether you can use a wrapper, whether you borrow, your marginal rate and your goals. To model your own position, you can contact our team for tailored advice.
