As a new buy-to-let landlord with two properties, how exactly does Section 24 affect the mortgage interest relief I can claim, and what's the most tax-efficient way to structure my finances now?
Quick Answer
Section 24 eliminates mortgage interest deduction for individual landlords, replaced by a 20% tax credit. For tax efficiency, consider holding properties in a limited company, where interest is an allowable expense.
## Navigating Section 24: Maximising Your Property Profits
Section 24 fundamentally changed how individual buy-to-let landlords account for mortgage interest, moving from a deductible expense to a basic rate tax credit. Understanding this shift is key to preserving your profit margins and is a critical insight for new landlords. The big positive here is that with careful planning, you can significantly mitigate its impact and increase your bottom line, identifying the best way to structure your finances.
* **Understanding the 20% Tax Credit**: As an individual landlord, you can no longer deduct your mortgage interest before calculating your taxable rental income. Instead, you receive a **basic rate tax credit** equivalent to 20% of your finance costs. This means if your mortgage interest is £5,000, you'll get a £1,000 tax credit. However, if you're a higher or additional rate taxpayer, this 20% credit won't fully offset your increased tax liability on the rental income that's now taxed at your marginal rate without the interest deduction. For example, a £10,000 annual interest payment, if you're a higher rate taxpayer, used to save you £4,000 in tax; now it only saves you £2,000 through the credit.
* **Limited Company Structure**: The most widely adopted solution for tax efficiency post-Section 24 is holding your properties within a **limited company**. For companies, mortgage interest remains a fully deductible business expense, reducing the company's taxable profits. These profits are then subject to Corporation Tax, which is 19% for profits under £50,000 and 25% for profits over £250,000. This is often far more favourable than paying 40% or 45% income tax as an individual.
* **Maximising Allowable Expenses**: Beyond mortgage interest, ensure you're claiming all legitimate allowable expenses such as letting agent fees, repairs (not improvements), insurance, legal costs for renewals, and accountancy fees. These *do* reduce your taxable rental income as an individual, so keep meticulous records.
## Common Section 24 Misunderstandings to Avoid
While the limited company structure offers benefits, it's not without its own complexities and is not suitable for every landlord. Here are some pitfalls:
* **Automatic Company Transfer**: Do not assume transferring existing properties into a limited company is always the best move without professional advice. This can trigger significant costs, including Stamp Duty Land Tax (SDLT) at an additional 5% surcharge, and Capital Gains Tax (CGT) on any uplift in value, which can be 18% or 24% for individuals depending on their income tax band. For a £300,000 property, the SDLT surcharge alone would be £15,000.
* **Ignoring Transaction Costs**: Setting up a limited company involves legal and accounting fees, annual returns, and potentially higher mortgage rates and arrangement fees compared to personal buy-to-let mortgages. BTL mortgage rates are currently between 5.0-6.5% for two-year fixes. Limited company rates are often slightly higher, so factor this into your overall return on investment (ROI on rental renovations).
* **Personal Property Usage**: Limited companies are business entities. If you plan to live in a property held by your company, this will create significant tax and legal complications.
* **Overlooking Income Tax on Dividends**: While Corporation Tax is paid on company profits, if you need to extract those profits for personal use, you'll typically do so via dividends, which are subject to further income tax. This can erode some of the initial tax advantages if not planned carefully (landlord profit margins).
## Investor Rule of Thumb
Always ensure any financial restructuring is undertaken with the explicit purpose of increasing net profitability, considering all associated taxes and costs, not just reducing one specific tax element.
## What This Means For You
Section 24 is a reality for individual landlords, but it doesn't have to cripple your portfolio. Most landlords don't lose money because they ignore tax planning, they lose money because they implement strategies without understanding the full implications.

Steven's Take
The shift with Section 24 was a game-changer, and it hit higher rate taxpayers particularly hard. From my own experience building a £1.5M portfolio, moving to a limited company for new acquisitions became non-negotiable for scaling. For your two existing properties, the critical step is to crunch the numbers with a specialist property accountant. Don't rush into transferring them without a full cost-benefit analysis. The CGT and SDLT implications can be staggering if not handled correctly. Focus on new acquisitions through a company where possible.
What You Can Do Next
Consult a specialist property tax accountant: Get tailored advice on whether a limited company transfer for your existing properties is viable, considering CGT and SDLT implications.
Review your current expenses: Ensure you are claiming all allowable expenses to minimise your individual rental income tax liability before the 20% credit.
Formulate a strategy for future acquisitions: Plan to acquire any new buy-to-let properties through a limited company to benefit from full mortgage interest deductibility.
