In this guide, we’ll explore why buying a buy-to-let in a limited company could be the best decision for landlords, break down the tax advantages, and provide case studies to illustrate the benefits and challenges.
Why? As a limited company, lenders assess affordability based on rental income coverage rather than your personal income.
Interest Cover Ratios (ICRs) for limited companies are often lower, typically starting at 125%, compared to 145% or more for individual landlords.
Example:
Limited Company: Requires only 125% coverage at the same stress test rate, allowing you to borrow more.
When setting up a limited company specifically for buy-to-let purposes, known as a Special Purpose Vehicle (SPV), lenders do not require a trading history.
Why Lenders Prefer SPVs:
One of the most compelling reasons for using a limited company is the potential tax savings.
One of the most compelling reasons for using a limited company is the potential tax savings.
Mortgage Interest Deduction: Individuals can no longer fully deduct mortgage interest from rental income due to Section 24 tax changes. Limited companies, however, can still deduct 100% of mortgage interest as a business expense.
Lower Tax Rate: Limited companies pay Corporation Tax (currently 19% in 2024) on profits, which is significantly lower than the higher personal income tax rates (40% or 45%) for higher earners.
Retained Earnings: Profits can be retained within the company to reinvest in future property purchases, avoiding personal tax liabilities.
Dividends and Salary Flexibility: Directors can pay themselves through dividends (subject to lower dividend tax rates) or a combination of salary and dividends for optimal tax efficiency.
Inheritance Tax Planning: Limited companies can be placed into trusts, offering potential inheritance tax benefits.
Expenses: Operating through a limited company allows you to offset more costs, such as accountancy fees, travel expenses, and property maintenance.
Changes by George Osborne: The Section 24 tax changes introduced by George Osborne significantly reduced tax relief for individual landlords, making the limited company structure a more attractive option.
Impact of Section 24: Individual landlords now pay tax on gross rental income, rather than net profits after mortgage interest.
This change has driven many landlords to incorporate, as limited companies are exempt from this rule.
Lenders are increasingly favouring limited companies due to their tax efficiency and straightforward business structure.
