I'm considering incorporating my 3 buy-to-let properties to escape Section 24. What are the *exact* costs involved (SDLT, capital gains elections, legal fees) and what's the typical timeline for a seamless property transfer to a limited company?
Quick Answer
Incorporating buy-to-let properties incurs significant costs, including Stamp Duty Land Tax (SDLT) at 5% for additional dwellings, Capital Gains Tax (CGT) at 18-24%, and legal/valuation fees from £3,000-£7,000 per property. The timeline often spans 4-9 months.
## What are the Costs of Transferring Properties to a Limited Company?
Transferring three buy-to-let properties to a limited company to mitigate the impact of Section 24 involves several distinct and often substantial costs. The primary cost considerations are Stamp Duty Land Tax (SDLT), potential Capital Gains Tax (CGT), and professional fees for legal and accounting services. For example, transferring properties worth a combined £750,000 could incur an SDLT liability of approximately £57,500 due to the additional dwelling surcharge.
### How is Stamp Duty Land Tax (SDLT) calculated for a company transfer?
SDLT is the most significant upfront cost when transferring properties into a limited company, as the company is treated as a new purchaser. Crucially, the additional dwelling surcharge of 5% applies to limited company purchases of residential property, on top of the standard residential rates. This means the company pays 5% on the £0-£125k portion, 7% on the £125k-£250k portion, 10% on the £250k-£925k portion, 15% on the £925k-£1.5M portion, and 17% above £1.5M.
For a portfolio of three properties, the SDLT is calculated on the total market value of the properties being transferred. This is a critical point; if the total value is, for instance, £750,000 (£250,000 per property), the SDLT calculation would apply the banded rates to the entire £750,000. So, for £750,000, it would be 5% on £125,000 (£6,250), 7% on £125,000 (£8,750), and 10% on £500,000 (£50,000), totalling £65,000. There are specific exemptions, such as 'incorporation relief' under Capital Gains Tax rules, which might affect the CGT position but do not exempt the company from paying SDLT. However, the 'multiple dwellings relief' which allowed a reduced rate for buying multiple properties in one transaction, was abolished from 1 June 2024. Therefore, the full additional dwelling rates now apply to such transfers without relief.
### Will I pay Capital Gains Tax (CGT) on the transfer?
Capital Gains Tax (CGT) is another significant consideration. When properties are transferred from individual ownership to a limited company, HMRC treats this as a 'disposal' by the individual. CGT will be due on any capital gain realised since the properties were acquired. The gain is calculated based on the market value of the properties at the time of transfer, minus the original purchase price and any allowable costs (e.g., stamp duty, legal fees, improvement works). Basic rate taxpayers face an 18% CGT rate, while higher and additional rate taxpayers are subject to a 24% rate on residential property gains. The annual exempt amount for 2026/27 is £3,000.
There is a potential relief known as 'incorporation relief' under Section 162 of the Taxation of Chargeable Gains Act 1992. This relief can defer the CGT liability if the property business is genuinely being transferred as a 'going concern' and meets specific criteria, primarily that the properties constitute a 'business'. HMRC guidance and case law indicate that merely owning and letting a few properties is unlikely to qualify as a business for this relief unless significant additional services are provided to tenants beyond basic landlord duties. If you provide services akin to a hotelier, for example, then it may be considered a business. This is a complex area, and specialist tax advice is essential to determine eligibility. If incorporation relief is not available, CGT becomes a substantial immediate cost. For example, if a property bought for £150,000 is now worth £250,000, and incorporation relief isn't available, a higher rate taxpayer would pay 24% on the £100,000 gain, amounting to £24,000 per property, subject to the annual exempt amount.
### What are the typical legal and accounting fees involved?
Professional fees for solicitors and accountants are necessary for a compliant and efficient transfer. Legal fees will cover the conveyancing process for each property being transferred to the company, drafting new mortgage deeds, and company formation. Depending on the complexity and number of properties, these fees can range from £2,000 to £5,000 per property, potentially £6,000 to £15,000 for three properties. Mortgage advisors will also charge fees for arranging new buy-to-let mortgages in the company's name, which can be several hundred pounds per property or a percentage of the loan amount.
Accounting fees are incurred for advice on the tax implications (SDLT, CGT, income tax), structuring the company, preparing a business plan (often required by lenders), and filing the necessary tax elections. These fees can range from £3,000 to £10,000, depending on the complexity of your tax situation and the number of properties. Ongoing annual accounting fees for a limited company are also higher than for an individual landlord, typically ranging from £1,000 to £3,000 per year for corporation tax and annual accounts filings, plus personal tax returns. This compares to potentially a few hundred pounds for a self-assessment for an individual.
### What is the typical timeline for a property transfer to a limited company?
The timeline for transferring properties into a limited company typically ranges from 3 to 6 months, but can extend beyond that depending on various factors. The process involves several key stages:
1. **Initial Planning and Advice (2-4 weeks):** This involves consulting with tax advisors, solicitors, and mortgage brokers to assess feasibility, understand tax implications, and determine the optimal structure. Obtaining specialist tax advice on incorporation relief is crucial at this stage.
2. **Company Formation (1-2 weeks):** Registering the limited company with Companies House. This is a relatively quick process.
3. **Mortgage Application (4-8 weeks):** Applying for new buy-to-let mortgages in the limited company's name. This is often the longest part of the process, as lenders will conduct due diligence on the company, its directors, and the properties. The Bank of England base rate at 3.75% influences these rates, and typical BTL fixes vary by lender and product; always compare the latest rates. Interest cover ratio (ICR) stress tests are also applied, with many lenders using 140% or higher reference rates, affecting loan eligibility.
4. **Legal Conveyancing (6-12 weeks):** The solicitors will handle the transfer of legal title for each property from you personally to the limited company. This involves searches, drafting transfer deeds, and dealing with Land Registry requirements.
5. **SDLT Payment and Land Registry (2-4 weeks post-completion):** SDLT must be paid within 14 days of completion. The Land Registry then updates the property title to reflect the new ownership, which can take several weeks or even months if there are delays.
Delays can arise from slow mortgage approvals, complex legal issues, or delays in obtaining necessary documents or information. Proactive engagement with all parties involved can help streamline the process.
## Benefits of Incorporating for Property Investors
* **Mitigation of Section 24 Impact:** Mortgage interest is fully deductible as a business expense for limited companies, unlike individual landlords who only receive a 20% tax credit on finance costs.
* **Lower Corporation Tax Rates:** Profits are subject to Corporation Tax (25% for profits over £250k, 19% for under £50k, with marginal relief between), which can be lower than higher or additional rate income tax (42% or 47% from April 2027) for individuals.
* **Greater Flexibility for Growth:** Easier to raise capital for future property purchases through shareholder loans or by attracting investors.
* **Estate Planning Advantages:** Transferring ownership of the company shares can be simpler than transferring individual properties, aiding succession planning.
* **Perceived Professionalism:** Operating through a company can present a more professional image to lenders and other businesses.
## Drawbacks and Considerations for Incorporation
* **Significant Upfront Costs:** SDLT and potential CGT on transfer can be very high, often outweighing the Section 24 benefits for smaller portfolios or properties with low capital gains.
* **Loss of Personal Use:** Properties transferred to a company cannot be used as a primary residence without severe tax implications.
* **Increased Administrative Burden:** More complex accounting and legal obligations, including annual accounts, company tax returns, and Companies House filings.
* **Higher Mortgage Costs:** Buy-to-let mortgages for limited companies often have higher interest rates and arrangement fees compared to individual BTL mortgages.
* **Extraction of Funds:** Profits are subject to Corporation Tax, and then personal income tax (dividend tax) when distributed to shareholders, potentially leading to double taxation.
## Investor Rule of Thumb
When considering incorporation, always calculate the immediate SDLT and potential CGT liabilities against the projected long-term tax savings from Section 24 mitigation over at least a 10-15 year horizon.
## What This Means For You
Most landlords don't lose money because they incorporate, they lose money because they incorporate without fully understanding the immediate costs and long-term implications. The decision to incorporate is irreversible without further significant cost, so robust due diligence on all tax liabilities and financial modelling is non-negotiable.

Steven's Take
Incorporating your portfolio is one of the biggest strategic decisions you'll make as a property investor, and it's not one to take lightly. I've seen too many investors jump into this purely to avoid Section 24, only to be hit with huge unexpected SDLT and CGT bills that wipe out years of potential tax savings. Remember, SDLT is based on market value, not your original purchase price, and incorporation relief for CGT is very hard to qualify for unless you're running a genuine property development business, not just holding rentals. My advice is to get multiple opinions from specialist tax accountants and solicitors who specifically deal with property incorporation. Model out the full costs over 10, 15, and 20 years, including professional fees and higher mortgage rates, against the tax savings. Sometimes, staying as an individual landlord, especially for smaller portfolios, can still be the more profitable route, even with Section 24.
What You Can Do Next
Consult a specialist property tax accountant: Discuss your specific portfolio and personal tax situation to understand potential CGT liability and eligibility for incorporation relief. Seek out accountants with a strong track record in property incorporation.
Obtain current property valuations: Get independent valuations for all three properties to accurately calculate potential SDLT and CGT liabilities before committing to the transfer. Contact local RICS-registered surveyors for accurate market values.
Engage a specialist property solicitor: Discuss the conveyancing process, legal fees, and any complexities related to transferring properties with existing tenants or mortgages. Use solicitors who specialise in limited company property transfers.
Speak with a whole-of-market mortgage broker specialising in limited company buy-to-let: Understand the available mortgage products, interest rates, fees, and interest cover ratio (ICR) stress tests for limited companies. Compare the latest rates.
Review HMRC guidance on incorporation relief: Access gov.uk/capital-gains-tax-incorporation-relief and gov.uk/guidance/stamp-duty-land-tax-relief-for-multiple-dwellings (though MDR is abolished for new transactions, understand the prior context).
Create a detailed financial model: Project the cash flow, tax savings, and costs over 10-20 years for both individual and limited company ownership, including all upfront and ongoing expenses. Use a spreadsheet to compare scenarios.
