How to Choose the Right Property Company Structure for UK Landlords in 2026

The structure you hold property in is not a paperwork choice, it is the single setting that decides how much of every year's rent you keep. Get it right and Section 24, the enacted 2027 property income rates and corporation tax all work in your favour. Get it wrong and you either overpay tax for a decade or face a five-figure bill just to switch. This guide gives you the framework a senior property tax adviser actually uses to make that call, with the 2026 numbers and the maths that matters.

Three wrappers are realistically on the table for a UK landlord: holding property personally (sole trader), a partnership, or a buy-to-let limited company. The decision turns on four things: your marginal income tax rate, your mortgage interest, whether you keep or spend the rent, and the latent gain in property you already own. Everything below is built around those four levers.

The four levers that actually decide your structure

Forget round-number rules like "incorporate above £50,000". Income level on its own is a poor guide, because a landlord with £30,000 of profit and a large interest-only mortgage can gain more from a company than one earning £80,000 with no borrowing. What genuinely moves the decision is this:

• Marginal rate. If rental profit lands in the 40% or 45% band, Section 24 is taxing you on income you never received as profit. That is where the company case opens up.
• Mortgage interest. A company deducts interest in full before corporation tax. An individual gets only a 20% credit (22% from 2027/28). The bigger the interest bill, the bigger the gap.
• Retain or extract. Companies shine when profit stays inside for the next deposit. Draw it all out and the second layer of dividend tax eats much of the saving.
• Latent gain. Moving existing property into a company is a disposal at market value, so the embedded capital gain sets the price of getting in.

Hold these four in mind as you read the structures below. The right wrapper is wherever they point in combination, not where any single one points alone.

The three structures compared

Here is how the options stack up across the points landlords actually weigh. No pricing is shown because the figures that matter are your own.

Tax on profit (2026/27)	Income tax 20% / 40% / 45%	Income tax on each partner's share	Corporation tax 19% to 25%
Tax on profit (2027/28)	Property rates 22% / 42% / 47%	Property rates on each share	Corporation tax (unchanged)
Mortgage interest relief	Restricted to basic-rate credit (Section 24)	Restricted to basic-rate credit (Section 24)	Full deduction before tax
Second layer on extraction	None	None	Dividend or salary tax on funds taken out
Income splitting	By legal ownership only	By partnership shares (flexible)	By share class and dividends
MTD for ITSA	Yes, if over threshold	Deferred, date to be confirmed	No (files CT600)
Cost to move existing property in	n/a	Limited	CGT 18%/24% + 5% SDLT surcharge
Best suited to	Small or low-geared portfolios; basic-rate; near-term sellers	Couples and family income splitting	Higher-rate, geared, growth-focused landlords

Sole trader: personal ownership

You own the property in your own name and report rents on your Self Assessment return. It is the simplest route and where almost every landlord begins. Profit is taxed at your marginal income tax rate, and you are fully exposed to Section 24, so mortgage interest only earns a 20% credit rather than a deduction. On disposal you pay Capital Gains Tax at 18% or 24% after the £3,000 annual exempt amount.

This works well if you are a basic-rate taxpayer, own one to three properties, carry little or no mortgage, or expect to sell within a few years. The administrative simplicity often outweighs any modest saving from incorporating, and personal ownership keeps open reliefs a company cannot access, including Private Residence Relief if you ever live in the property.

Partnership

A partnership lets two or more people own property together and split profit by their partnership shares rather than strictly by legal title. It can be a general partnership or a Limited Liability Partnership. The partnership files its own return; each partner then reports their share on their own Self Assessment.

Its real value is income splitting. A couple where one spouse has unused personal allowance or sits in a lower band can allocate more profit to that partner and cut the household bill. But a partnership is still inside Section 24, so it does not fix the interest-relief problem, and it adds a partnership return to the paperwork. A genuine, pre-existing letting partnership can also be a route to a more SDLT-efficient incorporation later under the connected-party rules, though HMRC scrutinises partnerships set up shortly before a transfer, so the substance has to be real.

Limited company

The company owns the property and you are director and shareholder. Crucially, companies are outside Section 24 and deduct mortgage interest in full before corporation tax. Profit is taxed at 19% on the first £50,000, at the main 25% rate above £250,000, and in a marginal band between (an effective 26.5% on the slice from £50,000 to £250,000). Those bands are shared between associated companies under common control, so running several SPVs splits the window.

Money taken out is taxed again, as dividends (10.75%, 35.75% or 39.35% in 2026/27) or as salary through PAYE. That second layer is why the company route favours landlords who reinvest rather than draw down. One distinction worth understanding: a company letting to genuine, unconnected tenants is normally not a close investment-holding company and keeps the 19% small-profits rate, whereas a company holding mainly shares, cash or connected-party property can be caught as a CIHC and pay 25% on all profits. For the full mechanics, see the complete buy-to-let limited company guide.

Section 24: the reason most landlords are even asking

Section 24 is the engine behind the whole incorporation debate. For individuals and partnerships, finance costs are no longer deducted from rental profit. Instead you get a tax credit worth a fixed percentage of your interest, capped at the lower of your finance costs, your rental profit, or your taxable income above the personal allowance. A higher-rate landlord is therefore taxed on a profit figure that ignores their interest, then handed back only basic-rate relief.

That credit is 20% for 2026/27. From 2027/28 it rises to 22% in line with the new property basic rate, so a basic-rate landlord sees no new wedge open up, but a higher or additional-rate landlord still relieves interest at 22% against a 42% or 47% charge. A company sidesteps all of this by deducting interest before corporation tax. The deeper the mortgage and the higher the band, the larger that advantage becomes. For a full walk-through, read how to claim mortgage interest relief under Section 24.

Worked example: where Section 24 bites

Take a higher-rate taxpayer with £40,000 of rental profit before interest and £18,000 of mortgage interest, with rental income sitting entirely in the 40% band.

• As an individual (2026/27): tax is charged on the full £40,000 at 40% (£16,000), then a Section 24 credit of 20% of the £18,000 interest (£3,600) is deducted, leaving £12,400 of tax. The interest costs £18,000 but only £3,600 of relief is given.
• Through a company: the £18,000 interest is deducted in full, leaving £22,000 of profit taxed at the 19% small-profits rate (£4,180). That profit can be retained to buy the next property without any further personal tax until it is drawn out.

The headline gap is stark while profit stays in the company. The honest caveat is the second layer: extract that retained profit as dividends and the saving narrows. This is exactly why the retain-or-extract lever matters as much as the tax-rate one.

The cost of getting in: CGT and SDLT on incorporation

The barrier that stops most landlords incorporating an existing portfolio is not the running tax, it is the entry cost. Moving personally-owned property into your company is a disposal at market value for CGT, even though no money changes hands and you control both parties. Two charges land at once:

• Capital Gains Tax at 18% or 24% on the gain since you acquired the property, after the annual exempt amount. See the complete CGT on property guide for how the gain is computed.
• SDLT at the standard rates plus the 5% additional-dwellings surcharge, because the company is a non-natural buyer of additional residential property (England and Northern Ireland, transactions on or after 31 October 2024). In Scotland this is LBTT plus the 8% Additional Dwelling Supplement; in Wales, LTT plus the higher rates for additional properties.

Section 162 incorporation relief can defer the CGT where you transfer a genuine property business wholly or partly in exchange for shares. It is automatic when the conditions are met, but HMRC requires the letting to amount to a real business under active management (the Ramsay v HMRC threshold), not one or two passive lets. Even when it applies, Section 162 does nothing for SDLT, the surcharge still has to be paid. That is why the most common pragmatic answer is to leave existing property where it is and buy future property through the company, accepting the dual administration that creates.

Charge on incorporating existing property	What applies	Available relief
Capital Gains Tax	18% / 24% on the latent gain, after £3,000 AEA	Section 162 incorporation relief (defers, if a genuine business)
SDLT (England and NI)	Standard rates plus 5% additional-dwellings surcharge	No general relief; narrow connected-partnership route only
LBTT (Scotland)	Standard rates plus 8% Additional Dwelling Supplement	No general relief
LTT (Wales)	Standard rates plus higher rates for additional properties	No general relief

What changes in April 2027, and why it tilts toward companies

From 6 April 2027, Finance Act 2026 (which received Royal Assent on 18 March 2026) charges property income at separate rates of 22% basic, 42% higher and 47% additional. These apply to England, Wales and Northern Ireland; only Scotland sets its own rates on property income. This is enacted law, not a proposal.

For an individual landlord, that is 2 percentage points more tax on rental profit at every band than on other income. The Section 24 reducer rises to 22% at the same time, so no fresh basic-rate wedge opens, but the headline rate on rental profit is now permanently above the ordinary income tax rate. A company pays corporation tax, which these property rates do not touch, so for higher and additional-rate landlords the 2027 change quietly widens the case for incorporation. For the detail, see the guide to the 2027 property income tax rates for landlords.

Making Tax Digital and the compliance load

Compliance is rarely the deciding factor, but it belongs in the picture. Making Tax Digital for Income Tax Self Assessment is live and applies only to individuals, not companies. The thresholds step down over three years: qualifying income above £50,000 from 6 April 2026, above £30,000 from 6 April 2027, and above £20,000 from 6 April 2028. Joint owners test the threshold against their share of gross rents, not the property's total. Partnerships are deferred to a date still to be confirmed.

A sole trader keeps it simple: digital records and quarterly updates once over the threshold, then a year-end declaration. A company carries more: annual accounts at Companies House, a CT600 corporation tax return, a confirmation statement, dividend documentation and director duties, but it sits entirely outside MTD for ITSA. If quarterly MTD reporting genuinely tips your decision, it points toward a company, though it should rarely be the headline reason to incorporate. Full detail is in the Making Tax Digital deadline guide.

Matching the structure to your strategy

Run the four levers against where you are actually heading:

If you hold one to three properties and plan little expansion, personal ownership usually remains the right call, especially as a basic-rate taxpayer with low gearing. The simplicity, the £3,000 CGT exemption each year, and access to Private Residence Relief if you ever occupy the property tend to beat a marginal incorporation saving.

If you are a higher-rate landlord building a portfolio with mortgage debt, a company is usually the stronger long-term home. Full interest relief, profit retention for reinvestment, and corporation tax rates insulated from the 2027 property rates all compound over time. The cost is the entry charge on any property you move in, which is why timing the build through the company from the start matters.

If you are planning your exit, think past this year. Personal ownership can use Private Residence Relief and the annual exempt amount on a direct sale; a company can be passed on through shares, which suits succession and staged gifting but does not get BPR for a standard buy-to-let portfolio. The wrapper should fit the destination, not just the current tax year.

A practical decision sequence

If you want a clean way to work through it, take these in order:

1. Find your marginal rate by adding rental profit to your other income. Basic-rate with no mortgage usually means stay personal.
2. Total your mortgage interest. The bigger it is, the more Section 24 costs you and the stronger the company case.
3. Decide retain or extract. Reinvesting favours a company; spending all the rent erodes the benefit.
4. Price the latent gain in any property you would move in, then check whether Section 162 could defer the CGT and accept the SDLT cost regardless.
5. Test it against your exit and time horizon before committing.

Where the numbers are close, model both routes side by side rather than relying on a rule of thumb. A specialist property accountant can run your actual figures, including spouse allowances, pension contributions and the 2027 rates, and tell you the break-even point for your portfolio rather than for a hypothetical one.

Common mistakes to avoid

• Incorporating on income alone. A high-income, no-mortgage landlord can be worse off in a company once dividend tax and compliance are counted.
• Forgetting the SDLT surcharge. The 5% charge on transferring existing property in is frequently overlooked and cannot be relieved by Section 162.
• Assuming Section 162 removes the CGT. It defers the gain into the shares; it does not delete it.
• Over-splitting into SPVs. Associated companies share the corporation tax bands, so extra companies can cost more tax than they save.
• Leaving the decision until the portfolio is large. The entry cost rises with value, so deciding before you buy is far cheaper than restructuring later.

The right structure for 2026 and beyond is the one that balances this year's tax efficiency against the cost of changing course later. For most growth-minded, higher-rate landlords with borrowing, the company route increasingly wins, particularly after the 2027 rates land. For smaller, lightly-geared or basic-rate portfolios, personal ownership often remains the sensible home. The only way to be sure is to run your own numbers against the four levers and your exit plan.
