Property Investment Company Structure: SPV vs Holding vs Group

There is no single best company structure for property investment. The right answer depends on whether you are reinvesting profits or drawing them out, how many properties and how many property types you hold, whether you let to family, and whether passing the portfolio to the next generation is in scope. Get the decision right at the start and you avoid expensive restructuring later; get it wrong and the cost often only surfaces once Section 24 bites or the portfolio grows.

This is a decision hub. It compares the five main structures in one table, walks a short decision tree, and works through the corporation tax mechanics that catch most multi-company portfolios. Where a structure deserves a full treatment of its own, we link to the deep-dive rather than repeat it here.

Why your property company structure decision matters

Your structure determines how much tax you pay on rental profit, how easily and at what cost you can access that profit, and what room you have to grow, bring in partners, or plan succession. Many landlords begin owning property personally and only look at a company once their portfolio expands or the tax position shifts.

The usual trigger is Section 24, which restricts mortgage-interest relief for individual landlords to a basic-rate (20%) tax credit rather than a full deduction. For a higher-rate landlord that difference is real money. Take an illustrative landlord with £100,000 of rental income and £40,000 of mortgage interest: holding personally, the interest no longer reduces taxable profit directly, and the basic-rate credit leaves a materially higher bill than the same properties would face inside a company where interest is fully deductible against profit before corporation tax. The figure varies with each landlord's other income, so treat any single number as illustrative, not a promise.

But structure is not only about today's income tax. It feeds into how you extract profit, your exposure to the associated-companies rules, and your inheritance-tax position. Those second-order effects are where the wrong choice quietly costs the most, and where this guide focuses.

The five structures at a glance

The table below compares the five structures property investors actually choose between. Each row links to the deep-dive for that option. Use it to shortlist, then read the relevant sections below and walk the decision tree near the end.

Structure	Best for	Corporation tax treatment	Section 24	IHT / succession	When it fits
SPV limited company	Most buy-to-let landlords	19% to £50k, 26.5% marginal £50k to £250k, 25% above (subject to divisor and CIHC rules)	No restriction; interest fully deductible	No BPR; freeze by share gift possible	Default for higher-rate landlords reinvesting profit
Holding company	Investors with several subsidiaries	Same rates; divisor splits limits across the group	No restriction at subsidiary level	Frozen-value preference shares; growth to next generation	Pooling cash and segregating risk across SPVs
Group structure	Mixed activities or JV partners	Same rates; group relief lets losses move between companies	No restriction at subsidiary level	As holding company, with more flexibility	Development plus rental, or multiple JV deals
Trading company	Genuine property development or trading	Same rates; profits are trading, not investment	Not applicable (development, not rental)	BPR possible only for real trading, capped £2.5m	Building or refurbishing to sell, not to let
LLP / partnership	JV between mixed-rate partners	Transparent; members taxed personally	Restriction applies to each member	Personal estate; no corporate freeze	Keeping personal ownership while sharing profit

The single most common pattern is a higher-rate landlord with one SPV. Everything beyond that should follow a genuine commercial need, because each extra company adds compliance and shrinks the small-profits band the group shares.

SPV limited company: the default for most buy-to-let

A special purpose vehicle is a limited company set up to hold rental property and do nothing else. It is the default for most buy-to-let landlords and the structure specialist lenders expect to see. The benefits are limited liability, full deductibility of mortgage interest (so Section 24 does not apply), and corporation tax rather than personal income tax on profit. Lenders generally want the standard SIC code 68209 (other letting and operating of own or leased real estate) on the Companies House record.

On corporation tax, the headline is more nuanced than the often-quoted "19% rising to 25%". For a standalone company the small profits rate of 19% applies to the first £50,000 of profit, the main rate of 25% applies above £250,000, and an effective 26.5% rate applies to the slice between the two through marginal relief (CTA 2010 Part 3A, the relief computed under s.18B with the standard fraction, currently 3/200, set by Parliament under s.18). That 26.5% is higher than both surrounding rates and is exactly where multi-company portfolios tend to land once the limits are divided, as the corporation tax section below explains. For the full SPV treatment, including lender criteria and naming, see the SPV guide and the buy-to-let limited company guide.

Holding companies and group structures

A holding company owns the shares of one or more subsidiary SPVs; a group is two or more companies under common control, usually with a holding company at the top. These structures buy you three things. First, risk segregation: a problem in one subsidiary is ring-fenced from the others. Second, group relief, the ability to surrender losses from one company against profits in another (CTA 2010 Part 5), which smooths tax across a portfolio where some properties run at a loss while others profit. Third, exempt inter-company dividends: cash can move up from a subsidiary to the holding company without a further corporation tax charge, letting you pool funds at the top for reinvestment.

The cost is real. Every company in the group needs its own accounts, CT600 and confirmation statement, and the associated-companies divisor shrinks the small-profits band each company can use. A group earns its keep on genuine size and complexity: several distinct property types, joint-venture partners who need clean separation, or a development arm that must be insulated from the rental side. Adding a holding company before that need exists is over-engineering. For the loss-surrender mechanics see the group relief page and the eligible-groups rules; for moving cash up the group efficiently see the dividend-conduit mechanics.

Property trading versus property investment companies

The trading-versus-investment line is one of the most misunderstood points in property structuring. Long-term letting is an investment activity, not a trade. Genuine development or trading, buying, building or refurbishing property to sell rather than to hold, can be a trade. The courts have confirmed the line (Pawson v HMRC [2013] UKUT 050).

Why it matters: Business Asset Disposal Relief, the reduced-rate CGT relief on selling a business, applies only to qualifying trading disposals. It does not apply to a property held for letting. So there is no CGT advantage in wrapping rental income inside a "trading" company, and doing so can actually blur the tax position. BADR also is not the 10% relief many older articles still quote: the rate rose to 14% from 6 April 2025 and to 18% from 6 April 2026, against a £1 million lifetime allowance. The practical takeaway: if you genuinely develop and also let, keep the two activities in separate companies, and do not expect trading reliefs on the rental side.

LLPs and partnership structures

A limited liability partnership is tax-transparent: it does not pay tax itself, and each member is taxed personally on their share of the profit. That makes an LLP useful where partners are in different tax brackets, or where you want to keep personal ownership while sharing profit on a joint venture, sometimes with a corporate member alongside individuals.

The limits are important. An LLP does not escape Section 24: because members are taxed as individuals, the mortgage-interest restriction applies to each member's share just as it would to a personal landlord. And the mixed-membership partnership rules block the simplest schemes that try to divert profit to a low-taxed corporate member. An LLP is a profit-sharing and joint-venture tool, not a route to full mortgage-interest deductibility. For that, the limited company route is the one to compare against personal ownership.

The corporation tax reality for multi-SPV portfolios

This is the section most "types of property company structure" guides skip, and it is where the real money sits. Two rules routinely turn the headline 19% rate into something much higher.

The associated-companies divisor (CTA 2010 ss.18D and 18E). Companies under common control are "associated" and must share one £50,000 small-profits limit and one £250,000 upper limit between them. So if you hold five single-property SPVs under common control, each company's small-profits band is not £50,000 but £10,000, and the upper limit per company falls to £50,000. Profit that you assumed would be taxed at 19% instead lands in the 26.5% marginal band, or at 25%.

Worked example A, single SPV. One SPV makes £30,000 of rental profit. It has no associated companies, so the full £50,000 small-profits band is available and the whole £30,000 is taxed at 19%: corporation tax of £5,700.

Worked example B, five associated SPVs. The same landlord instead holds the properties in five SPVs under common control, each making £30,000 of profit. The £50,000 band is divided by five to £10,000 per company. In each company, £10,000 is taxed at 19% and the remaining £20,000 falls into the marginal band at an effective 26.5%. Each company pays roughly £1,900 plus £5,300, about £7,200, against £5,700 for the same profit in one company, and that gap repeats five times over. Multiplying companies has raised the tax rate, not lowered it. See the marginal relief page for the full mechanics.

The close investment-holding company trap (CTA 2010 s.18N). A close company is a CIHC unless it exists wholly or mainly for a permitted purpose, the relevant one being holding land that is let commercially. Crucially, a letting is treated as commercial only if it is not to a connected person or a relative. A CIHC is denied the small profits rate entirely (s.18A(1)(b)) and pays the 25% main rate flat on all its profit.

Worked example C, family-tenant SPV. An SPV lets its only property to the owner's adult child. Because the tenant is connected, the letting is not "commercial" for s.18N, the company is a CIHC, and its £30,000 profit is taxed at 25% (£7,500) with no access to the 19% band at all. Most arm's-length buy-to-let SPVs are not CIHCs, but family lettings, director-occupied property and similar connected arrangements fall into the trap. The full carve-out is set out on the close investment-holding company page.

Extracting profit from a property company

How you plan to take money out of the company shapes which structure is right, because every extraction route has its own tax. There is no universal optimum; it is reader-specific.

• Reinvestment. If you are ploughing profit back into more property, leaving it in the company is efficient: you pay corporation tax once and reinvest the rest, with no second layer of personal tax. A director's loan can return capital you originally lent the company tax-free while the credit balance lasts.
• Dividends. Dividends are paid from post-corporation-tax profit and then taxed personally above the £500 dividend allowance, at the 2026/27 dividend rates. The combined corporation-tax-then-dividend cost is what you compare against personal income tax on the same profit. The dividend tax page works the numbers.
• Salary and pension. A salary is deductible for the company but taxable for you, with employer National Insurance above the secondary threshold; employer pension contributions can be an efficient route for longer-term extraction.

The key planning point: a structure that is efficient for accumulating profit (a lean SPV reinvesting everything) is not automatically efficient for someone who needs regular income out of the company. Decide the extraction plan first, then choose the structure that serves it.

Inheritance tax and succession

This is where the old advice is most dangerous. It is often claimed that company shares qualify for Business Property Relief after two years, taking the value out of inheritance tax. That is wrong for a property investment company. BPR is denied to a business consisting wholly or mainly of holding investments, and letting property is an investment activity (IHTA 1984 s.105(3); confirmed in Pawson v HMRC [2013] UKUT 050). A standard buy-to-let company does not get BPR, so do not structure around a relief you will not receive.

Where a business is genuinely trading and BPR does apply, Finance Act 2026 now caps combined 100% business and agricultural property relief at £2.5 million from 6 April 2026, with 50% relief on value above the cap (IHTA 1984 s.124D). For most family property companies the realistic inheritance-tax lever is not BPR at all but a value-freeze: the founder takes frozen-value preference shares while growth shares are issued to the next generation, so future growth accrues outside the founder's estate, with the share gift treated as a seven-year potentially exempt transfer. That planning needs care and is set up at formation rather than retrofitted.

The cost of incorporating an existing portfolio

If you already own property personally, moving it into a company is not a paper exercise. It is a disposal at market value for capital gains tax, even though you receive shares rather than cash, and it can trigger Stamp Duty Land Tax too.

Capital gains tax. Section 162 incorporation relief (TCGA 1992 s.162) can defer the CGT where you transfer a genuine property business as a going concern in exchange for shares. HMRC and the courts (the Ramsay v HMRC line) expect real, active management, so a handful of passively-let properties may not clear the bar. Where it does apply, the relief rolls the gain into the base cost of the shares rather than eliminating it.

SDLT. This is the trap. Section 162 relieves CGT only, not SDLT. The company normally pays SDLT (including the additional-dwelling surcharge on residential property) on the market value transferred in, unless a genuine pre-existing letting partnership can use the FA 2003 Schedule 15 partnership route. There is no longer a Multiple Dwellings Relief to soften it.

Worked example D, the break-even. A higher-rate landlord incorporates a portfolio with a large pregnant gain and a high market value. Even with s.162 deferring the CGT, the SDLT on the transfer can run well into five figures. Against that one-off entry cost you weigh the projected annual saving from full interest deductibility and corporation tax. If the annual saving is, say, several thousand pounds, the SDLT alone can take several years to recover, which is why incorporation rarely suits a small, low-geared, basic-rate portfolio. Model it before you commit. See incorporating without triggering CGT, the CGT-on-transfer calculation, and SDLT group relief for moving property between companies later.

Setting up and running the company

Once you have chosen a structure, formation itself is straightforward: incorporate at Companies House or through an agent, choose the SIC code that matches the activity (68209 for letting), appoint directors and shareholders, and adopt suitable articles. Open a dedicated company bank account and keep company and personal money strictly separate. Register for Corporation Tax within three months of starting to trade, set up PAYE if you will take a salary, and register for VAT only if taxable turnover exceeds £90,000, which residential rents (being exempt) do not usually create.

On ongoing obligations, here is the correction that matters: a limited company is outside Making Tax Digital for Income Tax. MTD for ITSA applies to individual and unincorporated landlords (phasing in from 6 April 2026 at £50,000 of qualifying income, 6 April 2027 at £30,000 and 6 April 2028 at £20,000), not to companies. A company instead files annual statutory accounts, a CT600 corporation tax return and a confirmation statement, and keeps board minutes for dividend and loan decisions. MTD for ITSA is therefore part of the personal-ownership comparison, one more reason some landlords look at a company, not a duty the company carries. For the full formation walkthrough, see the landlord incorporation step-by-step guide.

A decision framework: which structure fits you

Work through these questions in order. Each one narrows the choice.

• Are you reinvesting or extracting? Reinvesting everything favours a lean SPV that retains profit. Needing regular income means the dividend and salary cost has to be modelled before you commit, and may tip a borderline case back to personal ownership.
• Higher-rate or basic-rate, now and in future? A confirmed higher-rate position (especially with significant mortgage interest) points to a company; a basic-rate landlord with one or two low-geared properties often does better personally once entry costs are counted. Factor in where your income is heading, not just where it is.
• One property type or several? A single residential portfolio is one SPV. Mixed residential and commercial, or development plus rental, points toward separate companies, and only then toward a holding company or group to tie them together.
• Family succession in scope? If you want to pass value down, build the freeze-and-growth share structure in at formation rather than retrofitting it, and do not rely on BPR for an investment company.
• Do you let to family or connected persons? If yes, watch the CIHC trap (s.18N): a connected-tenant company loses the small profits rate entirely.
• How many companies? Default to as few as the commercial need allows, because the associated-companies divisor penalises multiplying companies. Add a second company for a reason, not by default.

If your answers point in different directions, that is the signal to get the structure modelled rather than guessed. The structure-tax-efficiency angle is explored further in our tax-efficient property investment structure guide.

Common mistakes, and getting it right

The recurring errors are predictable. Choosing on today's circumstances alone, ignoring where income and gearing are heading. Ignoring the associated-companies divisor and the CIHC trap, then being surprised by the corporation tax bill. Over-engineering with a holding company or group before it earns its keep. Letting to family inside a company without realising it forfeits the small profits rate. Underestimating the SDLT entry cost on incorporation, or assuming s.162 relieves it. And building around an inheritance-tax relief (BPR) that an investment company never gets.

The way to avoid all of them is the same: decide the structure on the full picture, income, extraction, succession and entry cost together, not on a single headline rate. Because the interactions between corporation tax, CGT, SDLT and IHT are exactly what catch people out, a structure-choice decision is one worth modelling with a property tax specialist before you incorporate anything.
