I'm a limited company landlord. How does Section 24 interest relief restriction affect my personal tax liability if I also have income from other sources, and what are the best strategies to mitigate this impact from my buy-to-let portfolio?

Quick Answer

Section 24 directly impacts individual landlords, not limited companies. For limited company landlords, personal tax arises from profit extraction via salary or dividends, which needs careful planning.

## Understanding Section 24 and Its Limited Company Implications Many landlords, myself included, have navigated significant tax changes over the years. One of the most impactful for individual landlords has been Section 24, formally known as the restriction on finance cost relief for residential landlords. Instituted fully from April 2020, this legislation prevents individual landlords from deducting mortgage interest and other finance costs from their rental income before calculating their tax liability. Instead, they receive a basic rate tax credit of 20% on these costs. This change primarily affects higher and additional rate taxpayers, as the 20% tax credit is significantly less than the 40% or 45% relief they previously received, effectively increasing their taxable income and, therefore, their personal tax bill. However, it's crucial to understand that **Section 24 does not directly apply to limited companies**. A limited company is a separate legal entity, and its profits are subject to Corporation Tax, not personal income tax. Therefore, mortgage interest and other finance costs remain a fully deductible expense for a limited company when calculating its taxable profits. This is a primary reason why many landlords have chosen to incorporate their property businesses. The tax implications for you as a limited company landlord arise when you extract profits from the company, not from the operating profits of the property portfolio itself before distribution. ## Tax-Efficient Profit Extraction for Limited Company Landlords For a limited company landlord with other income sources, strategic profit extraction is paramount to minimise personal tax liability. The key is to manage the flow of funds from the company to yourself in the most tax-efficient way possible, considering your overall income picture. * **Salaries and National Insurance Contributions**: Paying yourself a salary from your limited company is an option. If your other income is high, a larger salary could push you into higher income tax brackets and incur significant National Insurance contributions (NICs) for both you and the company. However, a small salary can be tax-efficient, particularly if it's set at the personal allowance threshold or just below the NICs threshold, allowing the company to deduct it as an expense. For instance, a salary structured to stay below the primary threshold for employee NICs and secondary threshold for employer NICs can be very efficient if you don't have other significant employment income. * **Dividends and Personal Income Tax**: After deducting all allowable expenses, including corporation tax at 19% for profits under £50,000 or 25% for profits over £250,000 (with marginal rates in between), the remaining profits can be distributed as dividends. Dividends aren't subject to National Insurance contributions. You get a tax-free dividend allowance of £500 (as of April 2024). Beyond this, dividend tax rates apply: 8.75% for basic rate taxpayers, 33.75% for higher rate taxpayers, and 39.35% for additional rate taxpayers. If you have substantial income from other sources, dividend income can quickly push you into these higher bands, increasing your personal tax burden. For example, if your other income already places you in the higher rate bracket, a substantial dividend payout would be taxed at 33.75% on anything above the allowance, making careful planning essential. * **Directors' Loans and Repayments**: If you've personally lent money to your company for property purchases or renovations, repaying these directors' loans is tax-free. This is an excellent way to extract funds without incurring income tax or corporation tax, as it's simply the repayment of a debt. It underscores the importance of proper accounting and documenting any personal funds injected into the company. * **Pension Contributions**: Contributing to a pension through your limited company is a highly tax-efficient strategy. The contributions are deductible as an expense for the company, reducing its corporation tax liability. They also offer personal income tax relief at your marginal rate, effectively reducing your personal taxable income. This is a powerful tool for long-term wealth building while mitigating current tax burdens. * **Retaining Profits for Reinvestment**: Rather than extracting all profits, consider retaining some within the company for future property acquisitions or significant refurbishments. This capital can be used to grow your portfolio, generating more income for the company down the line, without triggering immediate personal tax liabilities. Keeping profits within the company is often prudent for expansion, but ensure you have a clear business plan for these retained funds. ## Strategies to Mitigate Personal Tax Impact as a Limited Company Landlord Given that Section 24 doesn't directly hit your limited company, the focus shifts to smart profit management and personal financial planning. Here's how you can mitigate your personal tax impact: * **Optimise Your Salary and Dividend Mix**: Work with an accountant to determine the most tax-efficient blend of salary and dividends, considering your total income from all sources. Often, a small salary below the National Insurance threshold and dividends thereafter is recommended, but this depends entirely on your overall personal income and tax position. If your other income already exhausts your personal allowance, a small salary might not be the best option if it incurs NIC for no personal allowance benefit. * **Utilise All Available Allowances**: Make sure you are fully utilising your personal income tax allowance (£12,570 for 2025/26), your dividend allowance (£500 for 2025/26), and any other personal allowances or reliefs you may be entitled to. Every allowance used reduces your taxable income. * **Pension Planning**: As mentioned, company pension contributions are a superb way to reduce corporation tax and simultaneously boost your personal retirement savings tax-efficiently. This strategy is particularly effective for higher rate taxpayers. * **Spouse Utilisation**: If you have a spouse or civil partner who is a lower-rate taxpayer or has unused personal allowances, consider making them a shareholder or director in the company. This can allow for more flexible and potentially tax-efficient profit distribution across two individuals, utilising both sets of allowances and lower tax bands. However, be aware of 'settlement rules' which can apply if the spouse's share is disproportionately high without sufficient contribution. * **Accurate Expense Recording**: While not directly related to profit extraction, ensuring every legitimate business expense is recorded within your limited company reduces its taxable profit and, therefore, its corporation tax bill. This leaves more post-tax profit available for distribution or reinvestment. Things like professional fees, property repair costs, insurance, and travel expenses directly related to managing your portfolio should all be accounted for. * **Long-Term Capital Gains Planning**: If you eventually plan to sell properties within the company, the profits would first be subject to Corporation Tax. When you liquidate the company or extract remaining funds, this could be treated as capital distributions, which are generally more tax-efficient than income. This is a much longer-term strategy and requires careful tax advice when it comes to implementation. * **Professional Tax Advice**: This is not something you want to guess at. The tax landscape is complex and constantly changing. Engaging a specialist property accountant is not an expense, it's an investment. They can model different scenarios for profit extraction based on your specific circumstances and advise on the most tax-efficient strategies to keep you compliant and minimise your overall tax burden. They can also help you understand nuances like associated companies rules which impact the small profits rate of Corporation Tax. Remember, your goal is to grow your wealth. While Section 24 might not apply to your company, understanding its indirect impact through your overall earnings and how to manage profit extraction is fundamental to successful property investing in the UK as a limited company landlord. Always refer back to the exact figures for Corporation Tax at 19% for profits under £50,000 and 25% for profits over £250,000 (as of December 2025) when discussing corporate structuring and profitability. ## Investor Rule of Thumb For limited company landlords, the primary tax battle isn't Section 24, but rather how you get money out of the company and into your pocket whilst limiting personal tax, meaning strategic profit extraction is paramount. ## What This Means For You Being a limited company landlord offers significant tax advantages over individual ownership, largely bypassing the direct impact of Section 24, but it introduces new complexities around profit extraction. Navigating these options requires a clear understanding of your overall financial picture and the current tax rules. If you want to optimise your property company's tax position and ensure you're extracting profits in the most efficient way for your personal situation, this is precisely the kind of advanced planning and strategy we delve into with our students at Property Legacy Education.

Steven's Take

Okay, let's cut to the chase on Section 24 and limited companies. This is where a lot of misunderstandings happen, so listen closely. First off, a huge benefit of operating your portfolio through a limited company is that **Section 24 does not apply to the company itself**. This is a fundamental point. Your company can still deduct 100% of its mortgage interest and other finance costs before calculating its profits, which are then subject to Corporation Tax. This is a massive advantage compared to an individual landlord who only gets a 20% tax credit. Now, where it *does* become relevant to your personal tax liability is when you, as the director, extract money from that company. That's your personal income, and it will be taxed. From my own journey, moving properties into a company structure was a game-changer for scaling up. I quickly realised that while the company saves on tax, careful planning is needed for personal drawings. With the Bank of England base rate at 4.75% right now, and BTL mortgage rates typically between 5.0-6.5%, that full interest deductibility in a company is more valuable than ever. You really want to maximise what stays in the company or how you take it out. The strategies for extracting profits are critical here, especially if you have other income. You're looking to minimise your personal income tax. With the annual exempt amount for Capital Gains Tax now at £3,000, you want to be smart about how you structure any sales, too. Don't just blindly pull out all the profits; think about your overall financial picture and how dividends, salaries, or even director's loans fit in. Using retained profits to expand your portfolio further within the company is often the most tax-efficient route, delaying personal tax liability until you truly need the funds.

What You Can Do Next

  1. Review your company's financial statements: Understand the actual profits generated by your portfolio after deducting all allowable expenses, including mortgage interest, which means 100% of it, unlike an individual landlord.
  2. Consult with a tax advisor specialising in property: Before extracting any funds, get professional advice on the most tax-efficient methods for *your specific circumstances*, considering your other income sources. They can help you model different scenarios for dividends, salaries, and director's loans.
  3. Categorise company expenses accurately: Ensure all legitimate company expenses, including BTL mortgage interest at 5.0-6.5% for two-year fixed rates, are correctly recorded to minimise the company's taxable profit and thus its Corporation Tax liability (19% for profits under £50k, 25% for over £250k).
  4. Strategically plan profit extraction: If your other income pushes you into higher tax brackets, consider taking smaller dividends, utilising director's loans carefully, or retaining profits within the company for future property acquisitions or refinancing. Remember, Section 21 is due to be abolished, so retaining profits for potential property improvements is also wise.
  5. Consider leaving profits within the company: Reinvesting profits back into the company for portfolio growth, such as buying more properties or refurbishing existing ones to meet at least an EPC C rating by 2030, is often the most tax-efficient long-term strategy as it delays personal tax events.
  6. Understand Capital Gains Tax on company sale: Be aware that when you eventually sell the company or its properties, CGT applies to you personally on the proceeds you extract, not the company. Current CGT rates for residential property are 18% for basic rate taxpayers and 24% for higher/additional rate taxpayers, with an annual exempt amount of £3,000.
