Is a property company a tax efficient option

Many property investors wonder whether setting up a limited company to hold their rental properties would be more tax efficient than owning them personally. It’s a sensible question, especially in today’s tax environment where the rules have shifted considerably. However, there’s no one-size-fits-all answer. Whether a property company makes sense depends on your individual circumstances, the number of properties you own, and your wider financial picture.

The corporation tax advantage (and why it’s smaller now)

Historically, holding properties in a company was often tax efficient because corporation tax rates were significantly lower than higher-rate income tax. That advantage has largely evaporated. For the 2024/25 tax year, corporation tax sits at 19% for most companies, whilst higher-rate income tax for property investors is 40% (or 45% for additional rate taxpayers).

At first glance, the 21-percentage-point gap still looks attractive. However, there’s a critical catch: when you eventually extract profit from the company as a dividend, you’ll pay dividend tax on top of corporation tax. This creates a “double taxation” effect. Even with dividend allowances factored in, the combined tax burden often exceeds what you’d pay under personal ownership, especially for substantial rental income.

Mortgage interest relief and the personal allowance trap

Before April 2020, buy-to-let mortgage interest was fully deductible against rental income for all landlords. That changed. HMRC now restricts mortgage interest relief to a flat rate of 20% for individual landlords, regardless of your actual tax bracket.

For a higher-rate taxpayer, this is punitive. If you’re paying 40% income tax but can only claim 20% relief on mortgage interest, you’re left nursing a 20% gap. Many assumed a property company would sidestep this—and technically it does. Companies can deduct all legitimate interest costs before calculating corporation tax liability.

However, relief at 19% corporation tax versus 40% personal income tax still leaves you exposed to the dividend taxation issue mentioned above. Run the maths carefully before deciding this is your silver bullet.

Capital gains tax considerations

When you sell a rental property held personally, you’ll face capital gains tax (CGT) on the profit. The CGT rate for property is currently 20% for higher-rate taxpayers (and 10% for basic-rate taxpayers), with an annual exemption of £3,000 for 2024/25.

If the property sits in a company, any gain is taxed at corporation tax (19%) when the property sells. On paper, that’s better. But again, when you want to extract that cash from the company, dividend tax applies—and you’re back to a combined burden that often exceeds personal ownership.

There’s also a significant anti-avoidance rule to consider: the Furnished Holiday Lettings (FHL) exemption. Properties qualifying as FHL can be treated more favourably under CGT rules if held personally, but this relief is denied to companies. If you have FHL properties, holding them personally is usually preferable.

Administrative and practical costs

Running a property company means filing annual accounts with Companies House, submitting a corporation tax return, adhering to corporation tax deadlines (typically nine months after year-end), and maintaining proper company records. Accountancy fees for a straightforward property company often run £800–£1,500 annually, depending on complexity.

For a single rental property, these costs quickly outweigh any marginal tax advantage. Even with multiple properties, you need the tax saving to be substantial enough to justify the additional compliance burden.

Inheritance tax and funding considerations

One area where property companies can genuinely shine is inheritance tax (IHT) planning. Shares in a company may qualify for business property relief (BPR) under certain conditions, potentially reducing the IHT burden when you pass assets to beneficiaries. This is worth exploring with a specialist if wealth transfer is a priority.

Additionally, obtaining buy-to-let mortgage finance is more challenging for companies than for individuals. Lenders are pickier, and rates tend to be higher. If you’re still in acquisition mode, personal ownership may keep doors open.

The bottom line

For most individual landlords, personal ownership remains the simpler and often more tax-efficient route. A property company makes strongest sense if you own multiple high-value properties, have complex commercial arrangements, or are focused on IHT planning.

Rather than relying on general guidance, your own tax position warrants a proper calculation. Variables like your income level, number of properties, mortgage debt, and future intentions all matter significantly.
