Good question — setting up a limited company (Ltd) for buy-to-let property investment has become increasingly popular in the UK, especially since tax rules changed for individual landlords.
Here’s a clear breakdown 👇
🏢 Advantages of a Limited Company Buy-to-Let
1. Tax Efficiency (especially for higher-rate taxpayers)
- 
Individuals pay Income Tax on rental profits (up to 45%).
 - 
Companies pay Corporation Tax on profits (currently 25% in 2025 for most companies, sometimes lower for smaller profits).
 - 
You can leave profits in the company to reinvest rather than drawing them as income — great for portfolio growth.
 
2. Mortgage Interest Relief
- 
Individuals can no longer deduct full mortgage interest from rental income (since 2020, replaced by a 20% tax credit).
 - 
Companies, however, can still deduct 100% of mortgage interest as a business expense before tax — a major advantage.
 
3. Limited Liability
- 
Your personal assets are protected — only the company’s assets are at risk if things go wrong.
 
4. Easier to Share Ownership or Pass On
- 
You can add shareholders (family, partners) or transfer shares for inheritance or tax planning.
 - 
This can make estate planning and succession easier.
 
5. Reinvestment Flexibility
- 
Profits can be reinvested into more properties without drawing income (and paying personal tax).
 - 
Helps compound portfolio growth.
 
⚠️ Disadvantages / Things to Consider
1. Higher Mortgage Costs
- 
Limited company buy-to-let mortgages often have higher interest rates and fees.
 - 
Fewer lenders offer them (though this is improving).
 
2. Accountancy & Setup Costs
- 
You’ll need company accounts, annual filings, and possibly accountant fees (£600–£1,200+/year).
 - 
Incorporation adds admin complexity.
 
3. Double Taxation (when taking profits personally)
- 
If you take money out (e.g., as dividends), you’ll pay Corporation Tax + Dividend Tax — though still often more efficient than income tax for higher earners.
 
4. CGT & SDLT Issues if Transferring Existing Properties
- 
Moving properties you already own into a company can trigger:
- 
Capital Gains Tax (CGT)
 - 
Stamp Duty Land Tax (SDLT) (including the 3% surcharge)
 
 -
