Britain’s landlords are being urged to resist the stampede into limited company structures, as accountants warn that reacting too hastily to looming tax rises could prove a costly mistake.
From April 2027, rental profits earned by unincorporated landlords will be taxed under a new property income regime at 22%, 42% and 47%, a two percentage point increase across every band, as confirmed in the Government’s technical note on the changes to property income tax rates. The squeeze comes on top of mortgage interest relief that remains restricted to a basic-rate credit, elevated borrowing costs and intensifying HMRC scrutiny of property tax arrangements.
At the same time, landlords with combined property and self-employment income above £50,000 are now within Making Tax Digital for Income Tax, which requires digital record-keeping and quarterly submissions to HMRC, a significant step up in compliance obligations, with the threshold falling to £30,000 from April 2027. Those yet to get their books in order can consult our landlord’s checklist for Making Tax Digital.
Little wonder, then, that incorporation has become the talk of the sector. A record 66,587 buy-to-let limited companies were formed in 2025, up 8% on the previous year, as landlords went corporate in record numbers. But chartered accountants caution that the surge, amplified by social media commentary presenting incorporation as a universal remedy — risks encouraging rushed decisions.
The appeal is not difficult to grasp. Companies pay corporation tax at between 19% and 25% depending on profits, against personal property income tax rates of up to 47% from April 2027. And unlike individual landlords, who lost full mortgage interest deductibility under Section 24, limited companies can generally deduct mortgage interest and finance costs as a business expense before corporation tax is applied.
For larger, geared portfolios that can mean materially better net yields, alongside limited liability and the ability to retain profits within the company to fund further acquisitions. The trade-offs, however, are real, as our guide to limited company buy-to-let versus personal ownership sets out in detail.
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 base decisions on long-term strategy rather than 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.”
Transferring personally held property into a company is, in effect, a sale and purchase, and the bill can be substantial. Stamp Duty Land Tax is typically payable on the market value of the properties transferred, while Capital Gains Tax may arise on the disposal into the company. Existing mortgages will usually need to be refinanced onto limited company products, often at different rates and under different lending criteria, and the ongoing administrative, reporting and legal responsibilities of running a company are considerably heavier than personal ownership.
HMRC is also paying closer attention. The taxman has stepped up scrutiny of incorporation relief and property structuring arrangements that fail to deliver their promised outcomes — part of a broader compliance crackdown that makes professional advice essential before any restructuring is undertaken.
Incorporation may dominate the conversation, but it is far from the only lever available. Transferring full or partial ownership to a spouse or civil partner can make use of unused personal allowances or lower tax bands, particularly where one partner remains a basic-rate taxpayer. Refinancing existing borrowing can ease pressure on profitability while rates remain elevated. Some landlords may be better served by restructuring their portfolios without incorporating at all, disposing of underperforming assets or rethinking future acquisition strategy.
For smaller or lower-geared portfolios, retaining properties in personal ownership with sensible long-term tax planning may remain the most commercially viable route, particularly where the costs of incorporation would outweigh the savings. A popular halfway house is to leave existing properties untouched and use a limited company only for future purchases, sidestepping the immediate SDLT and CGT consequences of a transfer.
Each option carries different tax and legal implications, and suitability will vary significantly with portfolio size, income levels and borrowing structure.
With the April 2027 changes approaching and compliance demands mounting, the pressure on landlords to act is real. But the consistent message from advisers is that structuring decisions should be tailored, forward-looking and aligned with long-term financial objectives, not a reflex response to a tax rise or a trending post.
