Key Autumn Budget Changes: Tax on Rental Income

One of the most significant announcements for landlords is the increase in tax rates for buy-to-let properties held in personal names. From April 2027, landlords will pay an additional 2% on taxable rental profits, resulting in the following rates:

Income Level	Tax Rate (from Apr 2027)
Basic Rate	22%
Higher Rate	42%
Additional Rate	47%

This additional 2% will apply only to rental income taxed through personal tax returns. Landlords in the higher and additional rate bands are expected to feel the biggest impact, particularly if they hold multiple properties.

Why this matters: The higher tax burden makes personal ownership less efficient and has pushed landlords to consider more tax-effective structures, such as limited companies.

Current Trends in Buy-to-Let Ownership

The buy-to-let market has been evolving over recent years, with changes in tax relief and now higher personal rental income taxes. As a result:

• Personal buy-to-let ownership is becoming less attractive

• Limited company ownership is on the rise

• Landlords are seeking more flexible and tax-efficient strategies

  
  

By forming a limited company, landlords can often reduce their overall tax liability, gain more control over property management, and plan for long-term portfolio growth.

Benefits of Holding Buy-to-Let Properties in a Limited Company

Here’s why many landlords are moving their properties into a limited company:

Benefit	Personal Ownership	Limited Company Ownership
Tax Rate on Rental Profits	22–47% (from 2027)	19–25% Corporation Tax
Mortgage Interest Relief	Restricted	Fully deductible
Portfolio Growth	Limited by personal finance	Easier to scale and manage multiple properties
Inheritance Planning	Can be complex	Easier to transfer shares to beneficiaries
Professional Image	Limited	More professional and structured setup

Key Advantages

1. Lower Tax Rates: Corporation tax rates (19–25%) can be more favourable than higher personal income tax rates.

2. Tax-Deductible Expenses: Mortgage interest and other costs are fully deductible.

3. Easier Transfer to Beneficiaries: Shares in the company can be transferred without triggering large Capital Gains Tax liabilities.

4. Flexibility for Growth: Limited companies can hold multiple properties and expand the portfolio efficiently.

   
   

Who Can Form a Limited Company?

Forming a limited company is straightforward:

• At least one director

• At least one shareholder (can be the same person)

• A registered UK office address

  
  

Once set up, the company can purchase, hold, and manage properties. Some landlords even transfer existing personal properties into the company to optimise tax efficiency.

Frequently Asked Questions About Limited Company Buy-to-Lets

Do I have to pay Stamp Duty?

Yes, in most cases, because the company is considered a new buyer.

Do I have to pay Capital Gains Tax?

Potentially, if the property has increased in value since its last purchase.

What are the corporation tax rates?

• Profits ≤ £50,000 → 19%

• Profits ≥ £250,000 → 25%

• Profits in between → marginal relief applies (tapered rate)

  
  

Do I need a deposit for a limited company mortgage?

Not always. Existing equity in your property can often be used for the deposit. Some lenders now offer buy-to-let mortgages with a 15% deposit.

Example Scenario: Personal vs Limited Company Ownership

Scenario: Sarah owns a buy-to-let property generating £20,000 annual rental profit.

Personal Ownership (Higher Rate Taxpayer):

• Taxable rental profit: £20,000

• Income tax: 42%

• Net profit after tax: £11,600

  
  

Limited Company Ownership:

• Corporation tax: 19%

• Net profit after tax: £16,200

  
  

Difference: By holding the property in a limited company, Sarah keeps £4,600 more per year to reinvest or distribute.

This simplified scenario demonstrates the potential tax savings, making the limited company structure increasingly attractive for landlords.

Buy-to-Let Mortgage Options for Limited Companies

Many lenders now offer products tailored for limited company buy-to-lets, including:

• Remortgages to improve cash flow

• Capital Raising for portfolio expansion

• Low-deposit options (from 15%)
