Cambridge Rental Limited Company Setup: Tax Benefits and Pitfalls

Thinking of going limited? Here's what to consider before restructuring your Cambridge rental business. From tax breaks to legal burdens, we'll help you unpack whether setting up a rental limited company in the UK makes sense for your portfolio.

Key Tax Advantages of Holding Property in a Company

The main incentive for landlords switching to a limited company structure is the potential for tax efficiency. As of 2025, limited companies pay corporation tax at a flat 19%, while personal income tax can reach up to 45% for higher-rate taxpayers. This difference in rates can lead to significant annual savings, especially for landlords with growing portfolios or substantial rental profits.

Mortgage interest relief is another major benefit. Personal landlords can no longer fully deduct mortgage interest from rental income, but limited companies can. This can dramatically shift your net profit, particularly if your investments are leveraged.

Limited companies also offer better options for reinvesting profits. Rather than drawing income and paying tax immediately, landlords can leave profits in the company to fund future purchases or development. When income is withdrawn, dividend and salary planning enables further tax optimisation—particularly if you have other income streams to balance.

Setup Costs, Admin Burden, and Legal Responsibilities

The advantages of company ownership come with caveats. There’s a marked increase in admin and legal compliance. You'll need to:

• Register and maintain a company with Companies House

• File annual accounts and corporation tax returns

• Maintain separate business bank accounts

• Appoint and pay for an accountant familiar with property structures

Unlike sole traders, company directors carry legal responsibilities, including fiduciary duties, transparency rules, and more formal bookkeeping. Mortgage availability can also be more limited and rates slightly higher—but lenders specialising in buy-to-let through limited companies are expanding their offerings in 2025.

When It Makes Sense: Portfolio Size and Long-Term Strategy

The decision to incorporate depends largely on your scale and goals. For landlords with one or two rental properties, particularly those without mortgages, the benefits may not outweigh the costs.

However, if you're building a multi-property portfolio, planning inheritance strategies, or expecting to reinvest most profits, incorporation can unlock meaningful tax and planning advantages. It also provides a clearer boundary between personal finances and business obligations.

As part of your strategy, consider:

• How long you plan to hold the properties

• Whether you’ll need to draw income immediately or can leave it in the business

• Your plans for succession or eventual sale
