Is the Limited Company Buy-to-Let Boom Over? What the 2026 Data Shows
Buy-to-let company formations fell 8% in the first eight months of 2026, with August down 22%. Why incorporation is slowing, how to compare personal and company ownership, and who still benefits.
Quick answer: Not over, but slowing. Hamptons data reported in September 2026 shows 41,483 buy-to-let companies set up in the first eight months of 2026, down 8% on the same period of 2025, and August was down 22% year on year. If the trend holds, 2026 will be the first full-year fall since 2008. The slowdown reflects fewer existing landlords moving properties into companies, because transfers can trigger Stamp Duty Land Tax and Capital Gains Tax. Most new buy-to-let investors still choose a company, so the question is whether it suits you, not whether it is fashionable.
What the Latest Company Formation Data Shows
Hamptons analyses Companies House data on buy-to-let company formations. Its September 2026 figures, as reported by PropertyWire and other trade outlets, are:
- 41,483 buy-to-let companies formed from January to August 2026, down 8% from 44,802 in the same months of 2025.
- August 2026 alone: 4,198 formations, down 22% from 5,363 a year earlier.
- About 443,000 buy-to-let companies were registered by the end of 2025, almost five times the 2016 figure.
- In 2025, an estimated 53% of the roughly 81,800 properties entering buy-to-let companies in England and Wales were transferred from personal ownership. So far in 2026, about 51% of properties entering companies are new purchases.
One caveat: a company formation count understates activity. A landlord who set up a company years ago and buys ten more properties through it adds no new company to these figures.
Why Formations Are Falling
Hamptons says most landlords who benefit from incorporating have already done it. Others, such as lower-rate taxpayers or those planning to sell within a few years, often find that transfer costs are not worth it. Moving a property you own personally into a company is treated as a sale, which can trigger Stamp Duty Land Tax and Capital Gains Tax. Those costs are paid up front, while the tax saving arrives slowly.
Personal Ownership vs a Company: What Actually Differs
| Personal ownership | Limited company | |
|---|---|---|
| Tax on profit | Income tax at your marginal rate | Corporation tax on profits |
| Mortgage interest | Restricted to a basic rate tax credit (Section 24) | Treated as a business expense |
| Taking money out | Profit is already yours | Salary or dividends are taxed again |
| Buying costs | SDLT, with the surcharge on additional dwellings | SDLT at the higher rates for residential purchases |
| Moving an existing property in | Not applicable | May trigger SDLT and CGT |
| Best suited to | Lower-rate taxpayers, short holds | Higher-rate taxpayers retaining profit to reinvest |
A company wins when profits are reinvested rather than withdrawn, because corporation tax is currently charged at between 19% and 25% depending on profit levels. It loses its edge when you need the income personally, because dividend tax comes on top. Property income tax rates for individuals also rise from April 2027, as we explain in our guide to the 2027 rates, which strengthens the case for a company in some portfolios.
Who Should Use a Company Now?
- New buyers who plan to hold and reinvest: a company from day one avoids transfer costs later.
- Existing landlords with large mortgages: Section 24 can make personal ownership costly, but the transfer costs must be modelled. See our UK landlord tax guide.
- Short-term holds and flips: a company is often less useful, since the benefit builds over years.
- Anyone planning to live off the income: dividend tax reduces the advantage.
How to Test Your Own Case
- List the property price, mortgage, rent and expenses for each property.
- Run personal and company ownership side by side in the Ltd company vs personal calculator.
- Check the effect of mortgage interest restrictions in the Section 24 calculator.
- For an existing property, estimate the SDLT and CGT cost of transferring. Our capital gains tax guide and capital gains tax calculator help with the CGT part, and the stamp duty calculator covers SDLT.
- Take advice from an accountant before you transfer anything.
Frequently Asked Questions
Is the buy-to-let company boom over?
Formations are slowing, down 8% in the first eight months of 2026, but companies remain the preferred route for most new buy-to-let investors.
Why are fewer landlords setting up companies?
Most landlords who gain from incorporating have already done so, and transferring an existing property can trigger SDLT and CGT, which makes it uneconomic for many.
Is a limited company better than personal ownership for buy-to-let?
It depends on your tax rate, how much debt you hold and whether you reinvest profit. Higher-rate taxpayers who reinvest often benefit. Those who need the income personally often do not.
Can I move my existing buy-to-let into a company?
Yes, but it is treated as a sale to the company, which can trigger SDLT and CGT. Model both before you decide.
Do companies pay the stamp duty surcharge?
Generally yes. Companies buying residential property pay the higher rates of SDLT, and individuals pay the surcharge on additional dwellings, so you pay the extra cost in both structures.
Key Takeaways
- Buy-to-let company formations fell 8% in January to August 2026, the first sustained decline in years.
- The slowdown reflects the cost of transferring existing properties, not a rejection of companies.
- Companies favour higher-rate taxpayers who reinvest. They suit those who withdraw income less.
- Always model SDLT, CGT and extraction tax before moving a property.
