Should You Incorporate Your Property Portfolio? A Detailed Guide for Landlords
In recent years, many landlords have asked whether they should move their property portfolio into a limited company. This question has become increasingly relevant following changes to mortgage interest relief and the wider tax landscape.
However, incorporation is not a simple “yes or no” decision. It requires careful consideration of tax, costs, and long-term objectives.
Why Are Landlords Considering Incorporation?
The main driver is the difference in how finance costs (e.g. mortgage interest) are treated.
For individual landlords
- Mortgage interest is not fully deductible
- Instead, relief is given as a 20% basic rate tax credit
This means higher-rate taxpayers can suffer a significantly higher effective tax rate.
For companies
- Mortgage interest is fully deductible when calculating profits
- This reduces taxable profits before corporation tax is applied
This difference alone can make a company structure much more attractive—particularly for highly geared portfolios.
Corporation Tax vs Income Tax
Company structure
- Profits taxed at:
- 19% (small profits)
- Up to 25% (main rate)
- Marginal relief applies between £50,000 and £250,000 profits
Personal ownership
- Rental profits taxed at:
- 20%, 40%, or 45% depending on income
At first glance, the company route appears more tax-efficient. However, this is only part of the picture.
The Extraction Problem
One of the most important (and often overlooked) issues is how you access the profits.
If profits are left in the company:
- They are only subject to corporation tax
But if you want to extract funds personally:
- Dividends are taxed (depending on your income band)
- Salary may trigger income tax and National Insurance
This creates a second layer of tax, which can reduce or eliminate the benefit of incorporation.
Key Advantages of Incorporation
1. Full relief for finance costs
A major benefit for landlords with significant borrowing.
2. Lower tax rates on retained profits
If profits are being reinvested rather than withdrawn, a company can be more efficient.
3. Greater control over timing of income
You can choose when to extract profits, potentially managing your personal tax position more effectively.
Key Disadvantages and Risks
1. Incorporation costs (CGT and SDLT)
Moving an existing portfolio into a company can trigger:
- Capital Gains Tax on disposal
- Stamp Duty Land Tax (including the 3% surcharge)
These costs can be substantial and often outweigh the benefits.
2. More complex administration
Operating through a company involves:
- Annual accounts
- Corporation tax returns
- Additional compliance costs
3. Double taxation on extraction
As noted earlier, profits may be taxed twice:
- Corporation tax
- Dividend or salary tax
4. Mortgage and financing considerations
- Fewer lenders available for companies
- Potentially higher interest rates
- Personal guarantees often required
When Incorporation May Work Well
Incorporation is often more suitable where:
- The landlord is a higher or additional rate taxpayer
- Profits are not needed for personal use (i.e. reinvested)
- The portfolio is growing or long-term focused
- There is significant borrowing, making full interest relief valuable
When It May Not Be Suitable
Incorporation may be less effective where:
- Profits are needed for day-to-day living
- The portfolio is already established and would trigger large CGT/SDLT costs
- Borrowing levels are low
- The landlord is a basic rate taxpayer
Incorporation vs Starting in a Company
A key distinction:
- New landlords can often start in a company structure with minimal friction
- Existing landlords face potential tax charges when transferring properties
This means timing is critical—early planning is far more flexible.
A Balanced View
As highlighted in the ICAEW material, whether a company structure is beneficial depends on multiple factors, including:
- Tax rates
- Profit extraction needs
- Financing levels
- Costs of transferring an existing portfolio

Conclusion
Incorporating a property portfolio can offer significant tax advantages—but only in the right circumstances.
The decision should be based on:
- Your income needs
- Long-term investment strategy
- The cost of restructuring
For many landlords, the key is not just “is a company better?”, but “is it better for me, given my situation?”
