Ownership Structure: Individual vs. Limited Company

Individual Ownership: How It Works

When you buy property in your personal name (or as a partnership), rental income is added to your other income and taxed at your marginal rate.
You can claim actual expenses like repairs, maintenance, agent fees, and insurance. Also, individual ownership has lower entry costs due to no company setup fees or annual.

However, all rental income is taxed immediately, even if reinvested and also, your personal assets are at risk if things go wrong.

Limited Company Ownership: How It Works

When you buy property through a limited company, the company is the legal owner. Rental income belongs to the company and is subject to corporation tax, not personal income tax. Mortgage interest and financing costs are fully deductible as business expenses. Profits can be retained in the company for reinvestment at corporation tax rates. Extracting profits via dividends or salary triggers additional personal tax.

However, limited company ownership requires annual accounts, corporation tax returns, companies House filings, and higher accountancy fees.

Who Should Use Individual Ownership?

Individual ownership makes sense if you have 1-2 properties with low or no mortgage debt, are a basic-rate taxpayer (earning under £50,270), need immediate access to rental income for living expenses, want simplicity with minimal admin, or plan to sell properties within 5 years (to utilize CGT annual exemption).

Example: A basic-rate taxpayer owns one mortgage-free buy-to-let generating £12,000 annual rental profit. Tax due: £2,400 (20%). Setting up a limited company would add complexity and accountancy costs without meaningful tax savings.

Who Should Use Limited Company Ownership?

Limited company structure is ideal if you’re a higher or additional-rate taxpayer (40-45% tax bracket), have 3+ mortgaged properties or plan to build a portfolio, want to reinvest profits rather than extract income immediately, are comfortable with increased admin and compliance requirements, or value asset protection and limited liability.

Example: A higher-rate taxpayer owns 5 buy-to-lets with £200,000 annual rental income and £120,000 mortgage interest. As an individual, tax liability would be £32,000+. Through a limited company with full mortgage interest deduction, corporation tax is approximately £15,200—saving £16,800 annually.
