I'm a higher-rate taxpayer looking to get into property. Does setting up a family investment company for BTL still make sense from a tax perspective, or are there better ways to structure it now?
Quick Answer
For higher-rate taxpayers, a BTL property company can still be tax-efficient, benefiting from Corporation Tax rates of 19-25% and full finance cost relief, compared to personal income tax and Section 24 restrictions.
## Tax Advantages of Using a Limited Company for Property Investment
Setting up a family investment company for buy-to-let (BTL) can still offer significant tax advantages for higher-rate taxpayers, primarily due to how rental income and capital gains are treated. When operating a BTL portfolio through a limited company, profits are subject to Corporation Tax rather than individual income tax. The Corporation Tax rate is 19% for profits under £50,000, 25% for profits over £250,000, and a marginal relief applies between these thresholds. This compares favourably to the higher income tax rates of 42% or additional rate of 47% that will apply from April 2027, or current higher rate of 40% and additional rate of 45% (using August 2026 facts), which individual landlords would pay on rental profits. For example, a higher-rate taxpayer earning £50,000 in rental profit individually would pay £21,000 in income tax (at 42% from April 2027), while a company with the same profit would pay £9,500 in Corporation Tax (19%).
Another key benefit is the treatment of mortgage interest. For individual landlords, Section 24 means mortgage interest is no longer deductible from rental income; instead, a 20% tax credit is applied. However, for a limited company, mortgage interest and other finance costs remain fully deductible against rental income before Corporation Tax is calculated. This is a substantial difference, particularly for highly leveraged portfolios. Furthermore, profits retained within the company for reinvestment are only subject to Corporation Tax, allowing for tax-efficient portfolio growth without immediate personal income tax liabilities. Any funds withdrawn from the company would then be subject to personal income tax (e.g., through dividends).
### Does this structure affect Capital Gains Tax?
Yes, the Capital Gains Tax (CGT) implications are also different. When a property is sold within a limited company, any capital gain is subject to Corporation Tax, not personal CGT. The Corporation Tax rate on such gains would be either 19% or 25%, depending on the company's overall profits. This is significantly lower than the 24% residential property CGT rate for higher/additional rate taxpayers when selling personally. For instance, a £100,000 capital gain on a property sold by a higher-rate taxpayer individually would incur £24,000 in CGT (after the £3,000 annual exempt amount), whereas the same gain within a company could result in £19,000 to £25,000 Corporation Tax, depending on overall profit levels, without immediate personal tax implications until funds are extracted. This structure also allows for easier succession planning within a family, as company shares can be transferred, potentially mitigating future inheritance tax issues.
### Are there any downsides or complexities to consider?
While attractive, operating a property business through a limited company introduces complexities and costs. Setting up and running a company involves administrative burdens, including annual accounts, company secretarial duties, and specific legal compliance. Mortgages for limited companies (often referred to as 'SPV' or 'Special Purpose Vehicle' mortgages) can sometimes have slightly higher interest rates and arrangement fees compared to individual BTL mortgages, though competition in this sector is growing. Additionally, extracting profits from the company to personal use typically incurs income tax on dividends, which can reduce the overall tax efficiency if funds are regularly needed. The initial transfer of properties from personal ownership into a company can also trigger Stamp Duty Land Tax (SDLT) and Capital Gains Tax, depending on the structure and whether the transfer qualifies for specific reliefs, such as 'incorporation relief' for a genuine property business. SDLT for additional dwellings is 5% on the £0-£125k portion, 7% on £125k-£250k, 10% on £250k-£925k, 15% on £925k-£1.5M, and 17% above £1.5M. Therefore, careful planning is essential, involving professional tax and legal advice.
## Benefits of a Property Company
* **Lower Tax on Reinvested Profits:** Rental profits taxed at Corporation Tax rates (19%-25%), allowing more capital for **portfolio growth** compared to individual income tax (42%-47% from April 2027).
* **Full Mortgage Interest Relief:** Finance costs are fully deductible against rental income, providing a significant advantage over the **20% tax credit** for individual landlords under Section 24.
* **CGT Efficiency on Sale:** Capital gains taxed at Corporation Tax rates (19%-25%), generally lower than the **24% personal CGT** rate for residential property for higher/additional rate taxpayers.
## Potential Drawbacks and Considerations
* **Higher Costs & Admin:** Increased costs for company formation, annual accounts, and potentially higher mortgage product fees.
* **Dividend Tax on Extraction:** Personal income tax is incurred when withdrawing profits via dividends, impacting overall **cash flow to individuals**.
* **SDLT on Initial Transfer:** Transferring existing properties to a company can trigger **SDLT at additional dwelling rates** (e.g., 5% on first £125k), and potentially CGT, unless specific reliefs apply.
## Investor Rule of Thumb
For higher-rate taxpayers intending to reinvest rental profits and grow a substantial portfolio, a limited company generally offers superior tax efficiency, primarily due to deductible finance costs and lower corporation tax rates compared to personal income tax.
## What This Means For You
Given the changes like Section 24 and the current tax landscape, operating through a limited company can indeed be a more tax-efficient strategy for higher-rate taxpayers looking to build a BTL portfolio. Most investors don't regret setting up the right structure; they regret not setting it up sooner or doing it incorrectly.

Steven's Take
Having built my own portfolio, I've seen first-hand how critical structuring is. For serious investors, especially higher-rate taxpayers, the limited company route often makes the most sense long-term. It's not just about the current tax rates; it's about the flexibility for future growth and tax-efficient reinvestment. I started with £20k and grew to a £1.5M portfolio in three years, and strategic structuring was a key part of that. Don't just look at the upfront costs; consider the long-term benefits of retained earnings and reduced income tax leakage, particularly with Section 24. While it adds a layer of complexity, the financial advantages for growth-focused investors are often compelling.
What You Can Do Next
Consult a qualified property tax accountant: Discuss your specific financial situation, existing portfolio (if any), and investment goals to determine the optimal structure. Find one via the ICAEW or ACCA directories.
Review limited company buy-to-let mortgage options: Compare rates and criteria from lenders specialising in SPV mortgages; contact a specialist broker such as Commercial Trust or The Mortgage Works.
Understand the costs of incorporation: Factor in company registration fees, annual accountancy charges, and potential legal fees for shareholder agreements. Visit Companies House for registration details.
