Setting up a UK property investment Company for Landlords
August 5, 2025
As a property investor, you’re dealing with some pretty tough challenges that are eating into your returns. The Section 24 mortgage interest relief restrictions have significantly altered the landscape, causing many landlords to pay substantially more tax while their rental income remains unchanged. Complex tax rules, inheritance planning headaches, and the constant stress of keeping up with ever-changing regulations can feel overwhelming when you’re trying to build a solid property portfolio.
At Optimise Accountants, we get these frustrations. We’ve walked hundreds of investors through these exact same challenges, helping them flip tax burdens into competitive advantages through expertly structured property investment companies.
The numbers are significant. A company pays Corporation Tax at 19% on profits up to £50,000 and 25% on profits above £250,000, with marginal relief in between – an effective marginal rate of 26.5% on profits in that band. These limits are divided between associated companies. Individual landlords pay income tax at 20%, 40% or 45% on rental profits.
Section 24 has been particularly hard on higher-rate landlords. Since 6 April 2020, individual landlords can only claim a basic-rate tax reduction on mortgage interest – 20%, rising to 22% from 6 April 2027 in England, Wales and Northern Ireland – while companies can deduct mortgage interest in full as a business expense.
Already own property? Buying new property through a company is straightforward. Moving property you already own into a company is usually treated as a sale for Capital Gains Tax and a purchase for Stamp Duty Land Tax, unless a relief applies. See our guide to transferring property to a limited company before you decide.
There are many tax reliefs, hence why so many people are busy setting up a limited company.
Your Property Investment Solutions: A Clear Path Forward

Let’s look at the three key steps that you will need to take
- Step 1: Strategic Consultation and Structure Design
- Step 2: Company Formation and Legal Setup
- Step 3: Tax Optimisation and Ongoing Support
Step 1: Strategic Consultation and Structure Design
Our 60-minute consultation starts by getting to know your specific situation. We dig into your current portfolio, future plans, family circumstances, and tax position to figure out whether a limited company makes sense for you. During this chat, we’ll examine specialised structures, including Family Investment Companies (FICs). We will ensure that you become a company director with all the necessary knowledge at your disposal, without requiring technical expertise.
This isn’t about selling you something. As one client put it, we take a “straightforward approach” in laying out clear options and pros/cons, giving you complete control over your decision.
Step 2: Company Formation and Legal Setup

Once you decide to move forward, we handle the entire property company setup process within 5 days. Here’s what that includes:
Company Registration: We register your company with Companies House using the right SIC codes. For property investment activities, we typically use SIC code 68209 (Other letting and operating of own or leased real estate) or 68100 (Buying and selling of own real estate), depending on the specific activity being undertaken.
Share Structure Optimisation: Unlike DIY services that offer basic, ordinary shares, we create sophisticated structures with features such as freezer, growth, and alphabet share classes. This flexibility allows you to extract profits efficiently through dividends taxed at 10.75%, 35.75% or 39.35% (from 6 April 2026), rather than higher income tax rates.
Articles of Association: We craft custom articles tailored specifically for property investment companies, incorporating provisions for rent guarantee arrangements and directorship succession.
Step 3: Tax Optimisation and Ongoing Support

Our relationship extends far beyond simply setting up your company. We establish robust management accounting systems and provide ongoing guidance on tax-efficient profit extraction, compliance obligations, and strategic planning.
Corporation Tax Management: Your property investment company benefits from the small profits rate of 19% on profits up to £50,000, with marginal relief for profits between thresholds. We make sure you’re maximising these allowances across your entire portfolio.
Family Wealth Planning: We help structure ownership to facilitate income splitting with family members, potentially allowing you to make better use of personal allowances and lower dividend tax brackets than would be possible with personal ownership.
Dividends paid to a spouse or adult children must reflect genuine share ownership. The settlements rules can tax the income on the parent instead, particularly where shares are given to children under 18.
| Stage | Activity (Title) | Key Aims |
|---|---|---|
| Step 1 | Strategic Consultation & Structure Design | Understand your portfolio, family circumstances, and tax position; assess whether a limited company or Family Investment Company (FIC) is suitable; provide clear pros and cons without sales pressure. |
| Step 2 | Company Formation & Legal Setup | Register company with Companies House (correct SIC codes); create advanced share structures (growth, freezer, alphabet shares); draft tailored Articles of Association for property governance. |
| Step 3 | Tax Optimisation & Ongoing Support | Implement tax-efficient profit extraction and manage corporation tax rates (19% for small profits, 25% for main rate, with marginal relief). Support income splitting, compliance, and long-term family wealth planning. |

Family Investment Companies (FICs)
A Family Investment Company is a private company designed to hold property and pass value to the next generation. Parents usually keep control through voting shares, while future growth builds in shares held by children or family trusts, using share classes such as growth, freezer and alphabet shares.
A FIC can reduce future Inheritance Tax exposure and gives families clear rules for who controls and benefits from the portfolio. It costs more to set up and run than a standard property company, and gifts of shares or cash into it have their own tax rules, so it suits families planning for the long term rather than every landlord.
Most landlords buying new property need a standard property company (often called an SPV). In your consultation we will tell you which structure fits your plans.
Financing Solutions
The tax benefits often offset additional costs of running a limited company, particularly for higher-yield properties or those with heavily leveraged portfolios.
We work closely with specialist commercial mortgage brokers who understand property investment vehicles and can navigate lender requirements smoothly. Our clients benefit from our established relationships and in-depth understanding of how various lenders evaluate property company formation applications.
Why Professional Setup Beats DIY Solutions
While online formation services may seem tempting, they pose serious risks for investors. DIY platforms rarely offer structured tax advisory or customise company structures for optimal tax efficiency on income and capital gains. Many automated systems overlook property-specific compliance requirements, such as ATED, SDLT group reliefs, or non-resident landlord registration.
Real Client Success Stories
One client praised our work in developing management account formats as a “valuable record and measurement system” for future growth and success. Another highlighted our property sector specialisation and depth of knowledge in SPV structuring and non-resident landlord compliance.
Our cloud-based accounting integration gives clients a real-time financial overview and reporting, ensuring complete transparency and control over their portfolio and company performance.
Your Investment in Success: Free Setup for Committed Clients
We believe in building long-term partnerships. When you become a retained client after setting up your property company, we add your formation fee back to your account as a credit against future invoices. This demonstrates our commitment to your ongoing success, rather than fleeting, transactional relationships.
This approach reflects our understanding that property investment is a long-term strategy that requires ongoing support, compliance management, and strategic guidance as regulations evolve and portfolios expand.

Frequently Asked Questions
Q1: Why should a landlord set up a property investment limited company?
A: Holding investments in a limited company can reduce tax on rental profits, allow full deduction of mortgage interest, and offer flexible profit extraction through dividends. It can also support succession planning and family wealth transfer strategies.
Q2: What makes Optimise Accountants different from DIY formation services?
A: Unlike generic services, we tailor share structures (e.g. growth, freezer, alphabet shares), draft bespoke Articles of Association, and build tax planning into the setup from day one. Our focus is on long-term savings and compliance, not just filing paperwork.
Q3: How long does it take?
A: Most formations are completed within 5 working days. We handle Companies House registration, share allocation, and legal documents, ensuring everything is done correctly and efficiently.
Q4: What tax benefits can landlords expect?
A: A company pays Corporation Tax at 19% to 25% (an effective 26.5% in the marginal relief band) and can deduct mortgage interest in full, but taking profits out as dividends is taxed again at 10.75%, 35.75% or 39.35%. Whether it saves tax depends on your tax band, how much profit you leave in the company and your plans for the properties.
Q5: Do you provide ongoing support?
A: Yes. We offer full accounting and tax services, including corporation tax returns, dividend planning, compliance with HMRC, and advice on family investment planning. We ensure your company continues to operate tax-efficiently and stays compliant.
