Should you incorporate your buy-to-let portfolio?

Transferring rental property into a limited company can save significant tax — but it triggers Capital Gains Tax and Stamp Duty on the same day.

When incorporation makes sense

You're a higher-rate taxpayer

Section 24 hits hardest at 40% and 45%. If your rental profit (after expenses but before mortgage interest) pushes you into higher-rate territory, incorporation can reduce your effective tax rate significantly.

You have significant mortgage interest

The more mortgage interest you pay, the bigger the Section 24 impact. If mortgage interest represents 40%+ of your rental income, incorporation may be worth the upfront cost.

You're holding long-term

Incorporation has high upfront costs (CGT + SDLT). If you plan to hold the properties for 10+ years, you have time to recover those costs through annual tax savings. Short-term holds rarely justify incorporation.

You're building a portfolio

If you're acquiring new properties, buying them in a limited company from the start avoids the CGT/SDLT hit on transfer. Existing properties can stay personal, new ones go into the company.

When it doesn't make sense

Low mortgage levels

If you own properties outright or have small mortgages, Section 24 doesn't hurt much. The upfront cost of incorporation (CGT + SDLT) may never be recovered.

Planning to sell soon

If you're selling within 5 years, the upfront incorporation costs likely exceed any tax savings. Better to stay personal and pay the Section 24 tax.

You're a basic-rate taxpayer

Section 24 has minimal impact at 20%. Corporation tax (19%) + dividend tax may not save you much, and the upfront costs are the same regardless of tax bracket.

You need to extract all profit

If you rely on rental income to live, extracting profit as dividends triggers personal tax. The company structure only saves tax if you can leave profit in the company.
