If you are a landlord or considering buy-to-let investment in Northern Ireland, you have probably heard that purchasing through a limited company can offer tax advantages. But is it the right approach for everyone? Here is what you need to consider.

What Is a Limited Company Buy-to-Let?

Instead of buying a rental property in your personal name, you set up a Special Purpose Vehicle (SPV), a limited company whose sole purpose is to hold property. The company takes out the mortgage and owns the property. Rental income goes into the company, and you extract profits as dividends or salary.

Why Are Landlords Considering This?

The main driver is the change to mortgage interest tax relief. Since April 2020, individual landlords can no longer deduct mortgage interest as an expense before calculating tax. Instead, they receive a basic-rate (20%) tax credit.

For higher-rate taxpayers, this significantly increased the tax bill on rental income. Limited companies, however, can still deduct mortgage interest as a business expense in full before calculating Corporation Tax.

Tax Comparison: Personal vs Limited Company

The tax treatment differs in several important ways:

Mortgage interest relief:

  • Personal name: 20% tax credit only
  • Limited company: Fully deductible as a business expense

Tax on rental profit:

  • Personal name: Income Tax at your marginal rate (20%, 40%, or 45%)
  • Limited company: Corporation Tax (currently 25%)

Extracting profits:

  • Personal name: Direct access to rental income
  • Limited company: Must be extracted via salary, dividends, or directors' loans, each with its own tax implications

Capital Gains Tax on sale:

  • Personal name: CGT rates apply (18% or 24% for residential property)
  • Limited company: Corporation Tax on gains, then potential tax on extraction

Who Benefits Most?

A limited company structure tends to be more advantageous for:

  • Higher-rate (40%) or additional-rate (45%) taxpayers who are most affected by the mortgage interest changes
  • Portfolio landlords building a larger property portfolio
  • New investors who do not need to transfer existing properties (and therefore avoid transfer costs)
  • Those who plan to reinvest profits rather than draw income immediately

It may be less suitable for:

  • Basic-rate taxpayers who already benefit from the 20% tax credit
  • Landlords with existing personal portfolios where transferring properties into a company would trigger Stamp Duty and Capital Gains Tax
  • Those who need regular income from their properties, as extracting funds from a company adds complexity and cost

Mortgage Considerations

There are practical differences when obtaining a buy-to-let mortgage through a limited company:

  • Mortgage rates for limited company BTL tend to be slightly higher than personal BTL rates
  • Fewer lenders offer limited company products, though the market has expanded significantly
  • Personal guarantees are almost always required from the directors
  • Lender criteria may differ; some require the company to have been trading for a minimum period, though many accept newly incorporated SPVs

A mortgage broker with experience in buy-to-let finance can help identify which lenders are most suitable for your situation.

Setup and Running Costs

Setting up an SPV is relatively straightforward, but there are ongoing costs:

  • Company formation: Typically under £100
  • Annual accounts and Corporation Tax return: Accountancy fees, typically £500 to £1,500 per year depending on complexity
  • Confirmation statement: Annual filing with Companies House
  • Company bank account: Some charge monthly fees

These costs need to be weighed against the tax savings to determine whether the structure makes financial sense for your situation.

Should You Transfer Existing Properties?

If you already own rental properties in your personal name, transferring them into a company is possible but comes with significant costs:

  • Stamp Duty Land Tax on the transfer (calculated on market value)
  • Capital Gains Tax on any increase in value since purchase
  • Legal and professional fees

For many landlords, these costs outweigh the benefits. It is often more practical to hold existing properties personally and purchase new acquisitions through a company. Professional tax advice is essential before making this decision.

Getting Professional Advice

The decision to buy through a limited company involves tax, legal, and mortgage considerations. We would always recommend:

  • Consulting an accountant who specialises in property tax to model the numbers for your specific situation
  • Speaking to a mortgage broker to understand the lending options and rate differences
  • Taking legal advice on company structure and director responsibilities
