Could incorporating my property portfolio into a limited company actually save me tax compared to owning individually, especially with current corporation tax rates and Section 24?
Quick Answer
Incorporating a property portfolio can save tax by allowing full mortgage interest deduction, unlike individual ownership impacted by Section 24. While Corporation Tax is 19%-25%, mortgage interest offset can significantly improve net cash flow for landlords.
From April 2020, Section 24 fully abolished the ability for individual landlords to deduct mortgage interest as an expense against rental income, instead replacing it with a basic rate tax credit of 20% on finance costs. This change significantly shifted the tax landscape, making incorporation an increasingly attractive option for many property investors, particularly those operating at higher income tax bands. The comparison fundamentally boils down to the difference between individual income tax rates (which can be up to 47% from April 2027 for additional rate taxpayers) and the current Corporation Tax rates of 19% (for profits under £50k) or 25% (for profits over £250k, with marginal relief in between).
### What are the main tax differences between individual and company ownership?
The primary tax difference lies in how rental profits are treated. For individuals, net rental profit (after allowable expenses, but before mortgage interest) is added to other personal income and taxed at your marginal income tax rate. With the 20% tax credit for finance costs, a higher rate taxpayer effectively pays tax on income that includes a portion of their mortgage interest, even if their actual cash profit is lower. For example, if an individual landlord has £20,000 in rental income and £10,000 in mortgage interest, they are taxed on £20,000 of income, receiving a £2,000 tax credit. If they are a higher rate taxpayer (42% from April 2027), they pay £8,400 in tax, less the £2,000 credit, resulting in £6,400 tax paid on what might be a much smaller cash profit.
Conversely, a limited company deducts all legitimate business expenses, including mortgage interest, from rental income to arrive at its taxable profit. This profit is then subject to Corporation Tax. The company's post-tax profits can then be reinvested or distributed to shareholders as dividends. While dividends are subject to dividend tax rates, the key advantage is the control over when and how profits are extracted, potentially allowing for greater reinvestment within the business or more tax-efficient profit extraction strategies over time, such as staggered dividend payments or retaining profits for future property purchases.
### How does Section 24 specifically impact individual landlords vs. companies?
Section 24's impact is solely on individual landlords, not companies. For an individual landlord, the actual mortgage interest paid is no longer a deductible expense. Instead, they receive a tax credit equivalent to 20% of their finance costs. This means that a basic rate taxpayer may not see a significant change, as their tax credit offsets their basic rate liability on the finance cost portion. However, higher and additional rate taxpayers are hit much harder. A higher rate taxpayer (42% from April 2027) effectively pays 42% tax on their gross rental income, then receives a 20% credit on the finance costs, meaning they are still paying tax on a portion of the finance costs at their higher marginal rate.
For a limited company, mortgage interest is treated as a standard business expense and is fully deductible against rental income before Corporation Tax is calculated. This creates a direct and often substantial cash flow advantage for companies, particularly for highly leveraged portfolios. For instance, a property generating £1,000 monthly rent with £500 monthly mortgage interest for an individual higher-rate taxpayer could see their taxable income artificially inflated, reducing their net cash flow. A limited company, however, would directly reduce its taxable profit by the £500 mortgage interest, leading to a lower Corporation Tax bill and more retained profit for reinvestment.
### What are the Capital Gains Tax (CGT) implications for companies vs. individuals?
When a property held by an individual is sold, any capital gain is subject to residential CGT rates of 18% for basic rate taxpayers and 24% for higher/additional rate taxpayers, after deducting the annual exempt amount (which is £3,000 for 2026/27). For a limited company, the sale of a property results in a capital gain that is treated as part of the company's overall profits and is therefore subject to Corporation Tax at 19% or 25%.
While the headline Corporation Tax rates can sometimes be lower than the higher rate CGT for individuals, the key difference lies in the double taxation scenario for companies. When the company sells a property, it pays Corporation Tax on the gain. If the owner then wishes to extract those post-tax profits from the company, they will typically do so via dividends, which are then subject to personal dividend tax rates. This 'double taxation' means that the overall tax leakage on a capital gain can be higher for a company than for an individual, especially if the funds are immediately needed personally. However, if the profits are to be retained and reinvested within the company for further property acquisitions, the initial Corporation Tax rate might be more favourable than immediate personal CGT, allowing more capital to compound within the business.
### Are there additional costs and complexities with company ownership?
Yes, incorporating and running a limited company comes with additional costs and administrative complexities. You will face setup costs, annual Companies House filing fees, and typically higher accountancy fees due to the need for statutory accounts, Corporation Tax returns, and potentially payroll if you pay yourself a salary. Legal fees for transferring existing properties into a company can be substantial, as this constitutes a property 'sale' and will trigger Stamp Duty Land Tax (SDLT) and potentially CGT. SDLT on residential property, for a limited company as an additional dwelling, is a 5% surcharge on top of the base residential rate, meaning 5% on the £0-£125k portion, 7% on the £125k-£250k portion, 10% on the £250k-£925k portion, and so on. This can be a significant upfront cost that must be carefully modelled against future tax savings.
Moreover, lenders often have different criteria and slightly higher interest rates for limited company buy-to-let mortgages compared to individual ones, as the risk profile is perceived differently. For instance, typical BTL fixes vary by lender and product; always compare the latest rates, but expect that limited company rates might be fractionally higher. The administration of a company also requires a deeper understanding of corporate governance, director responsibilities, and ensuring compliance with Companies Act obligations.
### When does incorporation make most financial sense for a property portfolio?
Incorporation generally makes the most financial sense for investors who are: 1) higher or additional rate income taxpayers, 2) planning to grow their portfolio significantly and reinvest profits, and 3) looking for an effective way to manage their estate and succession planning. The higher your personal income tax rate, the more Section 24 impacts your net profit, making the corporate structure's full mortgage interest deductibility more appealing. For instance, an individual higher rate taxpayer paying 42% income tax from April 2027 will find the 19% or 25% Corporation Tax rate on retained profits considerably more efficient.
If the plan is to continually acquire more properties, retaining profits within the company means those funds are only taxed at Corporation Tax rates, allowing a larger pool of capital to be reinvested and compounded. For example, if a company makes a £20,000 profit, after 19% Corporation Tax (if under £50k profit), £16,200 is available for reinvestment. If the same profit was made by an individual higher rate taxpayer, a significant portion would be paid in personal income tax, leaving less for reinvestment. Estate planning can also be simplified, as shares in a company can often be passed down more easily than direct property holdings, potentially mitigating future inheritance tax liabilities, although this requires specialist advice.
### What are the key considerations for existing portfolios versus new acquisitions?
For an existing portfolio, transferring properties into a limited company is generally a 'disposal' for tax purposes. This means you would trigger Stamp Duty Land Tax (SDLT) on the market value of the properties being transferred, which for an additional dwelling is the base residential rate plus a 5% surcharge. On a £250,000 property, this would mean paying 5% on the first £125k (£6,250) and 7% on the next £125k (£8,750), totalling £15,000 in SDLT. Additionally, Capital Gains Tax (CGT) could be due on any gain since the properties were acquired, as this is treated as a disposal from your personal ownership to the company's. These upfront costs of transfer must be carefully weighed against the long-term tax savings.
For new acquisitions, purchasing directly within a limited company avoids these transfer costs. You would still pay the additional dwelling SDLT rates (5% surcharge applies to companies as well), but you bypass the CGT on transfer and the second SDLT payment. Therefore, starting with a company structure for new purchases is generally simpler and more cost-effective from a tax perspective than incorporating an established, appreciated portfolio. Professional advice is essential to model these costs accurately and understand if the long-term benefits outweigh the immediate expenses.
### Strategic Advantages of Company Ownership
* **Enhanced Cash Flow for Reinvestment:** By deducting all mortgage interest and being subject to Corporation Tax (19% for profits under £50k, 25% for profits over £250k), more post-tax profit remains within the company for future property acquisitions. This means faster portfolio growth through compounding.
* **Succession and Estate Planning:** Company shares can be more easily transferred or gifted than physical properties, potentially simplifying inheritance planning and reducing future inheritance tax liabilities.
* **Asset Protection:** A limited company is a separate legal entity, offering a layer of protection for personal assets from business liabilities, provided corporate governance is properly maintained.
### Potential Downsides and Complexities
* **SDLT and CGT on Transfer:** Moving existing properties into a company triggers Stamp Duty Land Tax at additional dwelling rates (5% surcharge) and potential Capital Gains Tax on any appreciation.
* **Higher Administrative Costs:** Increased accountancy fees for statutory accounts, Corporation Tax returns, and Companies House filings are inevitable.
* **Mortgage Product Limitations:** Company BTL mortgage products can sometimes have slightly less competitive rates and stricter lending criteria compared to individual BTL mortgages.
### Investor Rule of Thumb
For higher-rate taxpayers focused on long-term portfolio growth and reinvestment, incorporating a property portfolio often offers significant tax efficiencies and cash flow advantages over individual ownership, despite increased administrative complexities.
### What This Means For You
Understanding the nuanced tax implications of limited company ownership versus individual ownership is critical for optimising your property investment strategy. Most landlords don't lose money because they make the 'wrong' decision on incorporation, but because they make it without fully understanding the long-term tax and cash flow consequences tailored to their personal circumstances.

Steven's Take
The move to limited company ownership for property portfolios isn't just about avoiding Section 24, although that's a significant driver for many. As someone who built a substantial portfolio with limited capital, I can tell you that cash flow is king. When you're growing, every penny you can retain in the business to reinvest makes a difference. The lower Corporation Tax rates, especially the 19% small profits rate for profits under £50k, compared to individual income tax rates of up to 47% from April 2027, mean you keep more of your gross profit to put towards your next deposit. However, it's not a blanket solution for everyone. You've got to weigh the initial costs of transferring properties, which include SDLT and CGT, against the long-term tax savings and the administrative burden. My advice always boils down to modeling your specific scenario. If you're a higher rate taxpayer with a clear growth strategy, it's almost certainly worth exploring in detail.
What You Can Do Next
Consult a specialist property tax accountant: Seek advice from an accountant experienced in property investment to model your specific situation, including current and projected income, mortgage interest, and portfolio size. They can help calculate potential SDLT and CGT on transfer versus long-term tax savings.
Review your existing mortgage terms: Contact your current mortgage lender or a mortgage broker specialising in buy-to-let finance to understand the implications of transferring properties to a limited company, including any early repayment charges or changes to interest rates for corporate lending.
Research Stamp Duty Land Tax implications: Use the gov.uk SDLT calculator (gov.uk/stamp-duty-land-tax/residential-property-rates) to estimate the SDLT payable if you were to transfer properties into a company, remembering the 5% additional dwelling surcharge for companies.
Assess your personal income tax position: Understand your current and projected marginal income tax rate (basic, higher, or additional) to accurately compare the impact of Section 24 on individual ownership versus Corporation Tax rates. Use HMRC's personal tax account service to review your tax history (gov.uk/personal-tax-account).
Evaluate long-term investment goals: Determine if your primary goal is rapid portfolio expansion and reinvestment (where corporate structure excels) or immediate personal income extraction (where individual ownership might be simpler).
Understand company administration requirements: Familiarise yourself with the ongoing obligations of running a limited company, including filing statutory accounts with Companies House and submitting Corporation Tax returns to HMRC, to assess the administrative commitment. Companies House website (gov.uk/government/organisations/companies-house) is a good starting point.
Consider the 'incorporation relief' criteria: Investigate if your existing portfolio qualifies for 'incorporation relief' under Section 162 of the Taxation of Chargeable Gains Act 1992, which can defer CGT on transfer if certain conditions (such as the properties constituting a 'business') are met. This requires specialist tax advice.
