UK landlords urged not to rush into limited company structures ahead of 2027 tax changes
As tax and compliance changes continue to reshape the UK buy-to-let sector, advisers are warning landlords against reacting too quickly to the growing trend of incorporation.
- Property income tax rates for unincorporated landlords are set to rise to 22%, 42% and 47% from April 2027, increasing pressure on rental profits across all tax bands
- Landlords earning over £50,000 are now within Making Tax Digital (MTD) for Income Tax, significantly increasing ongoing reporting and compliance requirements
- Mortgage interest relief remains restricted to the basic rate of 22%, continuing to erode net rental returns for higher-rate taxpayers
HMRC has stepped up scrutiny of property-related tax structures, with increased focus on arrangements that do not deliver expected tax outcomes
A record 66,587 buy-to-let limited companies were incorporated in 2025, an 8% year-on-year increase, highlighting a continued shift in ownership structures
UK landlords are increasingly reassessing how they structure and manage property portfolios ahead of significant tax changes due to take effect over the next two years.
The reforms will introduce a revised property income tax regime for unincorporated landlords from April 2027, with rental profits subject to higher rates across all tax bands.
At the same time, the rollout of Making Tax Digital (MTD) for Income Tax is already increasing compliance obligations for landlords earning over £50,000 annually, adding further administrative pressure to an already complex regulatory environment.
These changes come against a backdrop of ongoing pressure on landlords, including restricted mortgage interest relief, higher borrowing costs and increased HMRC scrutiny of property-related tax arrangements.
As a result, more landlords are exploring whether holding property through a limited company structure could offer greater long-term tax efficiency. This shift is reflected in incorporation data, with a record 66,587 buy-to-let limited companies formed in 2025 in the UK, an 8% year-on-year increase.
However, Chartered Accountants are warning that the surge in incorporation activity risks encouraging rushed decision-making, particularly as social media commentary increasingly positions limited company structures as a universal solution to rising tax burdens.
Simon Thomas, managing director at Ridgefield Consulting, said: “We have seen a noticeable increase in enquiries relating to limited company structures and portfolio restructuring since details of the upcoming changes were announced.
As more landlords move into higher-rate tax bands, the ability to pay corporation tax at between 19% and 25% (depending on profits) rather than personal property income tax rates of up to 47% is making incorporation increasingly attractive.
Whilst a limited company structure can offer tax efficiencies in certain circumstances, it is not a one-size-fits-all solution. A company is a separate legal entity with its own tax treatment and ongoing responsibilities, and moving personally held property into a company structure can trigger high costs, including Stamp Duty Land Tax, Capital Gains Tax considerations and remortgaging fees.”
He added that landlords should ensure decisions are based on long-term strategy rather than reacting to short-term policy changes or market commentary.
“Proactive planning is key. In many cases, incorporation may be appropriate, but equally, there are alternative approaches that may be more suitable depending on individual circumstances.”
Why incorporation is gaining traction
A key driver behind the rise in limited company formations is the difference in tax treatment between personal ownership and corporate structures. As more landlords are pulled into higher-rate tax bands, paying corporation tax at 19% or 25% instead of personal property income tax rates of 42% is understandably becoming more attractive.
Since the introduction of Section 24, individual landlords can no longer deduct full mortgage interest from rental income, with relief instead restricted to a basic rate tax credit. However, this does not apply to limited companies, as they can generally deduct mortgage interest and finance costs as a business expense before corporation tax is applied.
This can improve net rental yields, particularly in large portfolios, as well as offering limited liability, and retained profits can be used to scale portfolios faster than investing as an individual.
However, incorporation is not always straightforward or appropriate
Despite these advantages, restructuring a property portfolio is not a one-size-fits-all solution and can involve significant costs.
Key considerations include:
- Stamp Duty Land Tax (SDLT) is typically payable on transfer based on market value
- Capital Gains Tax (CGT) may arise on disposal into a company structure
- Existing mortgages will usually need to be refinanced onto limited company products, which may involve different lending criteria and rates
- Administrative and compliance obligations increase, limited companies have higher administrative and legal responsibilities, reporting and ongoing HMRC requirements
There is also increasing scrutiny from HMRC around incorporation relief and property structuring arrangements, making professional advice essential before any restructuring is undertaken.
What are the alternative planning approaches available?
While incorporation is currently being represented as the default response to rising tax pressure, it is not the only available option to landlords.
Depending on individual circumstances, alternatives may include:
- Spousal ownership transfers — Partial or full transfers between spouses or civil partners can help utilise unused personal allowances or lower tax bands. This can be particularly beneficial where one partner is a higher-rate taxpayer, and the other remains within the basic-rate threshold or has not used their personal allowance, potentially reducing the overall tax burden on rental income.
- Refinancing and debt restructuring — In some cases, landlords may benefit from reviewing existing borrowing arrangements for a better rate, which can help reduce pressure, particularly as high interest rates continue to affect profitability.
- Portfolio restructuring without incorporation — In some cases, landlords may benefit from restructuring ownership arrangements, disposing of underperforming assets or changing future acquisition strategies without moving existing properties into a company structure.
- Retaining personally held properties with long-term tax planning — For smaller portfolios or lower-geared properties, retaining assets in personal ownership may remain the most commercially viable option, particularly where incorporation costs outweigh potential tax savings.
- Using limited companies for future acquisitions only — Rather than transferring existing properties, some landlords are choosing to retain current assets personally while purchasing future investments
With tax changes approaching and compliance requirements increasing, landlords are under growing pressure to review how their portfolios are structured. However, advisers are warning against reactive decision-making driven by short-term policy changes or online commentary, particularly given the costs and complexity involved in incorporation.
Instead, landlords are being encouraged to take a tailored, forward-looking approach to structuring decisions, ensuring any changes align with long-term financial objectives rather than immediate tax pressures alone.
