Limited Company vs Personal Ownership: Which is More Tax-Efficient?

d company is one of the most consequential tax decisions a UK landlord can make.

The answer is not straightforward: what works brilliantly for one landlord's portfolio can prove costly for another.

This guide cuts through the complexity to give you a clear framework for making the right choice for your specific circumstances.

Understanding the Fundamental Difference

When you hold property personally, you are taxed on rental income as part of your total income tax liability.

Your profits sit alongside your salary, pension, or other earnings, and the combined total determines which tax band applies.

When you hold property through a limited company, the company is a separate legal entity.

It pays corporation tax on its profits at the current rate of 25% (for profits exceeding £250,000 per year), then retains or distributes those profits.

When you take money out of the company as dividends, you pay additional tax personally.

This distinction matters enormously because it fundamentally changes how your rental income is taxed, what expenses you can claim, and what happens when you eventually sell.

The Tax Rate Comparison

For basic rate taxpayers earning below £50,270 annually, personal ownership can work out more straightforward.

Your rental profits are added to your other income, and you pay 20% basic rate tax on the portion that falls within that band.

Limited companies pay corporation tax at 25% on profits above £250,000, with a small profits rate of 19% applying to companies with profits under £50,000.

For most property companies sitting in the middle ground, the 25% rate applies.

This means company ownership immediately faces a higher headline rate than basic rate income tax.

The apparent disadvantage disappears, however, once you consider that the company retains profits that can be reinvested without triggering further personal tax.

A basic rate taxpayer with £30,000 of rental profit pays £6,000 in income tax personally.

A limited company paying £30,000 in rental profit pays £7,500 in corporation tax, but those profits compound within the company without additional personal tax until extraction.

Mortgage Interest Relief: The Game Changer for Personal Landlords

The most significant shift in recent years came with the phased introduction of restrictions to mortgage interest relief for personal landlords.

Since April 2020, relief has been restricted to the basic rate of income tax, currently 20%, regardless of which income tax band you occupy.

This change has fundamentally altered the mathematics for higher and additional rate taxpayers.

Previously, a higher rate landlord could deduct their full mortgage interest at 40%, substantially reducing their tax bill.

Now they receive only 20% relief, creating a significant increase in their effective tax burden on rental income.

Allowable Expenses: Where the Rules Diverge

Both personal landlords and limited companies can deduct allowable expenses from their rental income.

However, the rules and practical application differ in important ways.

Personal landlords deduct expenses as they occur against their rental income.

These include maintenance and repairs (but not improvements), landlord insurance, letting agent fees, legal fees for tenancies, and accountancy costs.

The key restriction is that capital expenditure on improvements cannot be deducted—this must be added to the property's cost base for capital gains tax purposes.

Limited companies face identical rules on deductible expenses, but with one crucial addition: they can claim capital allowances on certain items that would merely reduce the cost base for a personal owner.

This includes items like fixtures and fittings, certain energy-efficient equipment, and structural improvements in some circumstances.

Capital Gains Tax: The Disposal Calculation

When you sell a rental property, the tax you pay depends critically on your ownership structure.

This is often where the biggest differences emerge.

For a higher rate taxpayer selling a property with a £100,000 gain, personal ownership could trigger CGT at 28%, equating to £28,000.

A limited company selling the same property pays corporation tax at 25% on the gain, so £25,000.

The difference appears marginal, but personal owners also have their £3,000 annual exemption available, reducing the taxable gain to £97,000 and the CGT to £27,160.

"The tax structure that looks cheaper during your holding period may prove more expensive on disposal.

Always model the complete lifecycle, not just annual running costs." — HMRC's guidance on property investment decisions

The calculation becomes more complex when you consider how to extract profits from a limited company.

If you extract gains as dividends, you may qualify for dividend nil rate (the first £500 of dividends is tax-free), and the effective rate on gains extracted as dividends depends on your total income.

This planning opportunity can reduce the overall tax bill, but requires careful structuring.

Incorporation: The Costs of Switching

Many landlords currently holding properties personally consider transferring to a limited company to benefit from future tax planning.

This process, known as incorporation, carries significant costs that must be factored into any decision.

Beyond SDLT, you must consider legal costs for the transfer, potential Capital Gains Tax on the deemed disposal at market value, and the cost of remortgaging (most lenders charge exit fees and new arrangement fees when changing ownership structure).

For a portfolio of modest value, these costs frequently outweigh any benefit from switching.

The Extraction Problem

One of the most misunderstood aspects of limited company ownership is extracting profits.

The company pays 25% corporation tax, leaving 75% of rental income as retained profit.

If you want to spend this money personally, you must extract it through dividends or salary.

Dividends from a limited company are taxed as follows, after the £500 dividend nil rate:

• Basic rate taxpayer: 8.75% on dividends within basic rate band

• Higher rate taxpayer: 33.75% on dividends above £37,700

• Additional rate taxpayer: 39.35% on dividends above £125,140

Consider a higher rate taxpayer with £50,000 of rental profit in a limited company.

After corporation tax at 25%, £37,500 remains.

Extracting this as dividends above the dividend nil rate and their personal allowance triggers dividend tax at 33.75%, costing approximately £12,656 in additional personal tax.

Total tax: £25,000 (corporation tax) + £12,656 (dividend tax) = £37,656 on £50,000 profit.

The effective combined rate is 75%.

Against a personal landlord paying 40% on the same £50,000 profit: £20,000 tax.

The company structure is substantially more expensive for this scenario.

When Personal Ownership Works Best

Personal ownership typically makes more sense when:

• You are a basic rate taxpayer with modest rental income

• You have significant mortgage interest costs (basic rate relief still applies)

• You may need to sell property and access proceeds flexibly

• Your portfolio is small enough that incorporation costs would exceed benefits

• You are close to retirement and want to simplify your tax affairs

• The property qualifies for private residence relief (e.g., you previously lived there)

When Limited Company Ownership Works Best

Company structures typically work better when:

• You are a higher or additional rate taxpayer with substantial rental income

• Your mortgage interest costs are low or you have significant offsetting expenses

• You plan to reinvest profits into property expansion

• You are building a long-term portfolio where retained profits compound effectively

• You want to protect your personal assets from potential liability

• You are establishing a clear separation between your personal and business finances

A Practical Framework for Your Decision

Rather than asking which structure is universally better, ask these questions in order:

1. What is your current income tax position?

   If you are a basic rate taxpayer with total income below £50,270, the case for incorporation is weaker.

   The headline corporation tax rate of 25% exceeds your personal basic rate of 20%.

2. How large is your rental profit?

   Larger profits mean higher marginal tax rates personally, making company extraction costs relatively less significant.

   A landlord with £150,000 annual rental profit faces 45% income tax on the portion above £125,140.

   A limited company pays 25%, and the combined rate after extraction may still work in the company's favour.

3. What are your mortgage interest costs?

   Higher mortgage interest relative to rental profit favours company structure post-2020, since the basic rate cap on personal interest relief creates an effective 20% ceiling regardless of your tax band.

4. Do you need to extract profits?

   If you reinvest everything, company structure allows compounding at 25% corporation tax without further personal tax.

   If you need regular income, model the full extraction cost carefully.

5. What will incorporation cost?

   Get quotes for SDLT, legal fees, and remortgaging.

   Calculate how many years of tax savings are needed to recover these costs before deciding to switch.

The Bottom Line

For most individual landlords with modest portfolios and standard mortgages, personal ownership remains the simpler and often more cost-effective choice.

The administrative burden of maintaining a limited company, the costs of incorporation, and the complexity of profit extraction frequently outweigh the theoretical advantages.

However, higher rate taxpayers with large portfolios, low mortgage costs, and reinvestment plans should seriously model the company route.

The restriction on mortgage interest relief has narrowed the gap significantly, but where rental income substantially exceeds mortgage interest, company structures can still deliver meaningful savings over the longer term.

The right answer depends entirely on your numbers.

Run the calculations for your specific situation before assuming that one structure universally dominates the other.

Tax efficiency is not a destination—it is a continuous assessment of what works best for your portfolio as it exists today and as you intend it to become.
