Incorporating your property business

Running a property business through a limited company has become increasingly popular, not least because the rate of corporation tax paid on profits will generally be lower than the rate of income tax paid by an unincorporated landlord. However, incorporation isn’t a straightforward tax-saving decision—it involves regulatory obligations, ongoing compliance costs, and changes to how you manage your finances. This guide explores the key considerations to help you decide whether incorporating your property business is the right move for your circumstances.

The tax efficiency argument

The headline benefit is clear: corporation tax is currently charged at 19% on profits up to £50,000, with rates of 25% above that threshold (from April 2023 onwards). By contrast, higher-rate income taxpayers pay 40% tax on rental income plus 2% National Insurance contributions, totalling 42%. Even basic-rate taxpayers face 20% income tax plus 9% National Insurance, reaching 29%.

The gap narrows considerably, though, when you factor in how you extract profit from the company. Paying yourself dividends triggers dividend tax—currently 8.75% for basic-rate taxpayers and 39.35% for higher-rate taxpayers. You’ll also benefit from the £1,000 dividend allowance. Alternatively, taking salary means paying both income tax and National Insurance again. The net position often depends on your personal tax circumstances and how much profit you need to extract annually.

Compliance and administrative burden

Incorporating means registering with Companies House and filing annual accounts and confirmation statements. These filings are a matter of public record—unlike unincorporated businesses, where financial details remain private. You’ll need to keep detailed records, maintain a separate company bank account, and ensure the company follows proper governance procedures.

Companies must file accounts within nine months of their year-end (or risk penalties), and you’ll need a tax return for each financial year. Additionally, if you employ staff or pay yourself salary, you become an employer, requiring PAYE registration and monthly submissions to HMRC. These administrative requirements incur both time and professional fees—typically £500–£1,500 annually with an accountant, depending on complexity.

Mortgage and lending implications

Many mortgage lenders are more cautious about lending to limited companies than to individuals. Buy-to-let mortgages for companies often attract higher interest rates and stricter affordability criteria. If you’re planning to refinance, expand your portfolio, or access additional lending, incorporation could make this harder or more expensive. It’s essential to check with your lender before incorporating—some existing mortgages have clauses restricting this transfer.

Capital gains and exit planning

When you sell a property held individually, you pay capital gains tax (CGT) at 20% for higher-rate taxpayers. Through a company, you pay corporation tax at 19% when the company makes the gain. However, extracting the proceeds as a dividend triggers further dividend tax, potentially resulting in a combined rate of 39.35% for higher-rate taxpayers—worse than going solo.

This matters most if you’re planning significant disposals. Conversely, if you intend to hold properties long-term and reinvest profits within the company, incorporation may be advantageous.

Losses and reliefs

Unincorporated landlords can offset losses against other income, including salary or pension contributions. Companies can carry losses forward to offset future profits but can’t offset against other income streams. If your property business generates losses—perhaps due to mortgage interest or renovation costs—incorporating may limit your tax relief options.

Making the decision

There’s no universal answer. Incorporation works well for landlords with substantial profits, strong business growth prospects, and secure mortgages. It’s less suitable for small portfolios, those planning near-term sales, or anyone struggling to access finance.

We’d strongly recommend running detailed projections based on your specific situation before deciding. The decision is relatively easy to reverse early on but becomes more complex once systems are established.

Conclusion

Incorporating your property business can deliver genuine tax savings, but only if the structure suits your circumstances. The compliance costs, administrative burden, and impact on borrowing must be weighed against potential benefits. Whether you’re exploring incorporation for the first time or reconsidering your current structure, professional guidance is invaluable.
