Should I buy a property through a limited company?

by Abbas Gulamhusein

This is one of the most common questions I get from landlords and property investors. The answer most people hope for is a simple yes or no. The answer I always give is that it depends on your specific situation, because there is no universal right answer.

The case for a limited company

The strongest case comes down to mortgage interest deductibility. If you're a higher rate or additional rate taxpayer, this often moves the decision on its own.

When you own a property personally as a landlord, you can deduct mortgage interest against rental income. But HMRC only gives you a 20% tax credit, regardless of whether you're a 40% higher rate taxpayer or 45% additional rate taxpayer. So if your mortgage interest is £20,000, you get a £4,000 credit. That's a significant gap between what you can deduct and what you should be able to deduct.

A company gets to deduct the full amount of mortgage interest as a business expense. No 20% restriction. A company pays corporation tax at 19-25% on profits, which is lower than the 40-45% personal income tax rate on rental income. For investors who don't need the rental income immediately, profits retained in the company are taxed at 25% rather than 40-45% personal income tax plus National Insurance.

Inheriting or transferring shares in a company is also more flexible than transferring property directly, which helps if you're planning family wealth transfers.

The case against

Mortgage availability is the first disadvantage. Buy-to-let mortgages for limited companies typically have higher interest rates and fewer products available than personal mortgages. If the extra mortgage cost eats away the corporation tax saving, the tax advantage evaporates.

Transferring existing properties into a company creates immediate tax costs. You'll face capital gains tax on any appreciation since you bought it, plus Stamp Duty Land Tax. Those costs can be substantial. The real advantage of the company structure is using it from the beginning for new purchases, not transferring existing properties across.

Compliance costs are higher. A company requires annual accounts, a corporation tax return, and confirmation statements to Companies House. You're paying accountancy fees for that compliance. A personal tax return is simpler.

Extracting profits from the company creates another issue. Money in the company isn't in your pocket. If you want to use it, you need to extract it via salary or dividend, both of which create tax costs. The corporation tax already paid on the profit means the total tax on extracted money might not be cheaper than the income tax you'd pay personally on the rental income.

Who it makes sense for

For an investor buying new properties with significant mortgage debt who's a higher or additional rate taxpayer, a limited company usually makes sense. You get the full mortgage interest deduction, profits are taxed at 25%, and money can be retained in the company if you don't need it. Mortgage rates matter, but for many investors they're close enough that the tax efficiency wins.

For an investor who owns properties outright with no mortgage, the advantage is much smaller. There's no mortgage interest to deduct. The only benefit is the company tax rate versus your personal rate.

For an investor with low borrowing who immediately needs rental income to live on, personal ownership is often more efficient. The extraction costs eat away the corporate tax saving.

Working out your situation

Think through these questions. What's your personal income tax position? Are you a basic rate, higher rate, or additional rate taxpayer? The higher your marginal rate, the more the company structure appeals. How much mortgage debt are you carrying? The more debt, the more valuable the full mortgage interest deduction becomes. Do you need the rental income immediately or can you leave it in the company? If you need it to live on, extraction costs matter more.

If you're transferring existing properties, what's the Stamp Duty Land Tax and capital gains tax cost? That calculation determines whether transferring makes financial sense.

This is an area where tax-efficient planning is significant, but it depends entirely on your specific facts. If you're an additional rate taxpayer with substantial buy-to-let mortgages, a company structure often makes sense. If you're a basic rate taxpayer with no debt, personal ownership is probably fine. If you're somewhere in the middle, you need to work through the details properly.
