There is no universally better option. For a UK residential rental, buying personally and buying through a company have different tax, borrowing, administration and sale consequences. A company may suit some investors who borrow to buy and plan to keep profits inside the business, but taking money out can create a further personal tax bill. Compare the full plan—from purchase and mortgage through rental income, profit extraction and eventual sale—before choosing.
This guide covers the UK framework only. Your residence, the property’s location and your individual circumstances can change the answer; the available facts are not enough to calculate which structure would cost you less.
What changes when a company owns the property?
With personal ownership, the individual or individuals named as owners own the property directly. With company ownership, the company owns the property and you own shares in the company. You may also act as a director, but company money and property are not automatically your personal assets.

It records its own rental income and expenses and pays Corporation Tax on its net profit. After that, profit can remain in the company for business use or be distributed, for example as dividends. A distribution can have a further personal Income Tax consequence.

How do the two ownership routes compare?
| Decision point | Personal ownership | Company ownership | What to check |
|---|---|---|---|
| Who owns the property? | The individual owner or co-owners named on the title. | The company owns the property; the individual owns shares. | Title, beneficial ownership, co-investors and governance arrangements. |
| Rental-profit tax | Individual tax rules apply. For UK residential landlords, relief on finance costs is restricted to the basic rate. | Company tax rules apply. The specific residential finance-cost restriction for individuals does not apply to companies. | Tax residence, other income, eligible expenses and current rules. This comparison alone does not establish the lower overall tax bill. |
| Using rental profit | Rental proceeds belong to the owner, subject to their tax position. | Profit may be retained after company tax or distributed, potentially creating personal tax. | How much you need to spend personally and how much you intend to reinvest. |
| Borrowing | Check actual personal buy-to-let mortgage offers. | Check actual company or special-purpose vehicle (SPV) offers, lender requirements and any guarantees. | Compare offers on the same property, loan size and assumptions; do not assume one route is always cheaper or available. |
| Administration | Keep property records and meet relevant individual tax-reporting duties. | Maintain company accounts and filings, separate finances and meet director duties. | Annual compliance costs and who will handle the work. |
| Sale or restructuring | Personal disposal rules apply. | The company disposes of its asset; getting sale proceeds out of the company is a separate consideration. | Expected holding period, sale plan and tax consequences at each relevant level. |
| Risk and liability | The individual is directly exposed to property obligations. | The company is a separate legal person, but that does not remove director duties or establish protection from every personal exposure. | Insurance, lender terms, guarantees and legal advice. |
How mortgage-interest relief differs in the UK
HMRC says that, from 6 April 2020, Income Tax relief on residential finance costs for individual landlords is restricted to the basic rate. HMRC’s guidance says UK-resident and non-UK-resident companies are outside that restriction and continue to receive relief for interest and other finance costs in the usual way. Read HMRC’s guidance on residential landlord finance-cost relief.
This is one part of the calculation, not proof that incorporation produces a lower total tax bill. The result also depends on how much profit is made, whether it is retained or distributed, your other income, eligible expenses and what happens when the property is sold.
Rank #2
What happens to rent and company profit?
HMRC describes taxable rental profit as rent less eligible expenses or allowances. Examples of potentially allowable rental expenses include insurance, agent and management fees, some legal fees and accountant fees. Its guidance distinguishes mortgage interest from principal repayments: the full mortgage payment is not an ordinary rental expense, and capital improvements are not deductible as ordinary rental expenses. See HMRC’s rental-income and expense guidance.

For a company, calculate what remains after company-level tax and expenses, then decide whether profits will stay in the company or be paid out. Retained profit may be available for business purposes; it is not the same as money available for your personal spending. If you expect to draw rental profits regularly, include the possible personal tax on distributions in the comparison.
How do borrowing and administration affect the choice?
The OTS identifies finance access and debt ring-fencing among commercial reasons landlords have considered incorporation. That does not mean a company mortgage is always more expensive, easier to get or free of personal guarantees: lenders set their own terms and assess each application. Obtain comparable offers for the ownership structure you are considering, including fees, guarantees and underwriting conditions.
A company also brings its own accounting and filing work. The OTS describes Companies House filing and accounting obligations, as well as personal duties for directors. Include the cost of professional support and the time required to keep company and personal finances properly separate.
Is a company more protective?
A company is a separate legal person, but that fact alone is not a guarantee that you will have no personal exposure. Director duties remain, and lender guarantees or other circumstances may matter. The available evidence does not establish the effect of every guarantee, claim or jurisdiction-specific rule. Check the proposed lender terms and get legal advice about the arrangement rather than treating incorporation as complete protection.
Are you buying through a company or transferring a property later?
Buying a new property through a company and moving a property you already own into one are different transactions. Tax and legal consequences depend on the property’s location, existing ownership and debt, transaction steps and any available reliefs. HMRC’s Spotlight 63 discusses potential complications, including Stamp Duty Land Tax, in a particular hybrid partnership arrangement; it is not evidence that an ordinary company purchase automatically triggers all of those taxes. Read HMRC Spotlight 63.

The OTS’s 2022 review found that over 85% of more than 3,500 survey respondents owned property individually or jointly, while just under 10% owned property through a limited company. The review also cited a report counting 47,400 buy-to-let companies incorporated in 2021, compared with 15,000 in 2015; it noted these figures were small relative to 2.9 million property businesses owned by individuals. These are historical survey and market figures, not current prevalence estimates or evidence that either structure is better. Read the OTS property income review.
How to make a practical comparison
- Confirm the jurisdiction. Identify where the property is, where you are tax-resident and which rules apply. The comparison above is for UK residential letting, not a universal rule.
- Set out the same investment assumptions for both routes. Use the same purchase price, borrowing, expected rent, eligible costs, holding period and sale plan.
- Model rental-year cash flow and tax. Account for the UK residential finance-cost restriction for individual landlords, company-level tax, eligible expenses and your other income.
- Choose what happens to profit. Estimate how much you will retain for reinvestment and how much you need to distribute for personal use.
- Compare real mortgage offers and compliance costs. Include lender fees, guarantees, company accounting, filings and the time or professional fees needed to manage them.
- Include the eventual sale or transfer. Consider tax and cash extraction at that stage, and seek professional advice before transferring property already owned personally.
The OTS’s evidence is useful for understanding the structural differences, but its historical tax rates should not be treated as current rates. Use current official guidance and advice based on your actual figures.
