For a higher-rate taxpayer planning to buy another BTL, what are the current practical strategies to minimise the impact of Section 24 on my taxable income, beyond incorporation?
Quick Answer
Higher-rate taxpayer landlords looking to buy another BTL can reduce Section 24's impact without incorporating by optimising finance structures, maximising allowable expenses, and considering income redirection, directly limiting their taxable income.
## Smart Strategies to Navigate Section 24 as a Higher-Rate Landlord
Section 24, introduced in April 2020, prohibits individual landlords from deducting finance costs, like mortgage interest, from their taxable rental income. Instead, you receive a basic rate tax credit of 20% on these costs. For higher or additional rate taxpayers, this means you're taxed on turnover, not profit, often pushing profitable ventures into a loss after your actual mortgage payments. As a higher-rate taxpayer, your income tax rate is 40% or 45%, but you only get 20% relief, creating a significant tax drag. Beyond incorporation, which is a major step and not always suitable, several practical strategies can help minimise this impact when acquiring another Buy-to-Let (BTL).
* **Maximising Allowable Expenses (Non-Finance Related)**: While finance costs aren't deductible, many other property-related expenses are. Diligently record and claim *every* allowable expense to reduce your net rental profit before the Section 24 calculation kicks in. This includes:
* **Management Fees**: If you use a letting agent, their fees are deductible. If you self-manage, you can't pay yourself a fee, but you can deduct costs for advertising, referencing, and legal documents.
* **Repairs and Maintenance**: Costs for repairing existing fixtures, fittings, and the property structure are fully deductible. Be careful not to confuse these with capital improvements, which are added to the property's base cost for Capital Gains Tax (CGT) purposes. For example, a new modern kitchen, part of significant refurbishment or 'best refurb for landlords', might be a capital improvement. However, replacing a broken boiler, costing around £1,500-£3,000, is a repair.
* **Legal and Professional Fees**: Costs incurred for drawing up tenancy agreements, eviction notices, accountancy fees, and advice on property matters are usually deductible.
* **Landlord Insurance**: Buildings, contents, and rent guarantee insurance premiums are all fully deductible.
* **Travel Costs**: Reasonable travel expenses for property inspections, dealing with tenants, or visiting agents are deductible.
* **Utilities and Council Tax**: If you pay these while the property is vacant, they are deductible.
* **Optimising Mortgage Structure**: While interest isn't deductible, how you finance can still matter.
* **Higher Loan-to-Value (LTV) on Interest-Only Mortgages**: By taking a higher LTV, you reduce the equity tied up in the property. While this increases the absolute interest payment, it means less of your own cash is subject to the drag of Section 24. Be aware, however, that BTL mortgage rates are currently between 5.0-6.5% for 2-year fixed and 5.5-6.0% for 5-year fixed, so higher interest payments always need to be carefully stress-tested against your rental income. Standard BTL stress tests require 125% rental coverage at a 5.5% notional rate.
* **Capital Raising on Your Primary Residence**: If you have equity in your main home, you could consider releasing capital to fund the deposit for your BTL. The interest on this borrowing *is not* tax-deductible against your rental income. However, it frees up your cash flow and could be part of a broader financial strategy.
* **Transferring Property/Income to a Lower-Rate Taxpayer**: If your spouse or civil partner is a basic rate taxpayer, or has little or no income, gifting or selling a share of the property to them means a portion of the rental income is taxed at their lower rate. This requires careful planning and consideration of CGT implications on the transfer, as well as Stamp Duty Land Tax (SDLT). The current additional dwelling surcharge for SDLT is 5% on purchase price. For example, transferring a 50% share of a property valued at £200,000 could trigger CGT on your deemed gain and potentially SDLT if any consideration (even existing mortgage debt) is involved.
* **Exploring Furnished Holiday Lets (FHLs)**: FHLs are treated differently for tax purposes than standard BTLs. They qualify as a trading business, meaning you can deduct 100% of mortgage interest from your rental income. FHLs also benefit from capital allowances on furniture and fixtures, and can qualify for certain CGT reliefs, like Entrepreneurs' Relief (now known as Business Asset Disposal Relief) if you eventually sell. However, FHLs require significant active management and meet strict occupancy conditions to qualify, making them less 'passive' than traditional BTLs. This might be considered a 'best refurb for landlords' if you are targeting the FHL market.
* **Maximising Reliefs (e.g., Replacement of Domestic Items Relief)**: This relief allows you to claim a deduction for the cost of replacing certain domestic items, such as beds, sofas, carpets, and white goods. This is distinct from repairs, as it covers the _replacement_ of items that were originally in the property and not a new item or an upgrade. Being diligent with these claims can add up and reduce your overall taxable rental income. This can significantly improve 'rental yield calculations'.
## Potential Tax Traps to Avoid
* **Not Delineating Repairs vs. Improvements**: As mentioned, repairs are deductible, but capital improvements are not. HMRC is strict on this. Replacing an old, like-for-like kitchen is a repair, but installing a new, significantly upgraded kitchen where one didn't exist, or enlarging it, is an improvement. Getting this wrong can lead to incorrect tax filings and potential penalties.
* **Ignoring SDLT Surcharge**: Remember the 5% additional dwelling surcharge for SDLT. This applies to any additional residential property purchase, meaning a £250,000 BTL property would incur an extra £12,500 in SDLT. This isn't deductible as an expense against income.
* **Underestimating Stress Test Requirements**: Despite the attractive BTL investment returns, lenders use a stringent stress test, often 125% rental coverage at a 5.5% notional rate for BTL mortgages. If your rent can't comfortably cover this, you won't get the mortgage, regardless of your personal income.
* **Falling Foul of HMO Regulations**: If your strategy involves multi-let properties, be acutely aware of HMO licensing requirements. For properties with 5+ occupants forming 2+ households, mandatory licensing applies. Minimum room sizes are crucial: 6.51m² for a single bedroom, 10.22m² for a double. Non-compliance can lead to massive fines and rent repayment orders.
## Investor Rule of Thumb
Focus on optimising what you can control: maximise allowable expenses, legally structure ownership for tax efficiency, and thoroughly understand the tax implications before committing to a new BTL purchase.
## What This Means For You
Navigating Section 24 as a higher-rate taxpayer requires a strategic, detailed approach. It's not about avoiding tax, but legitimately reducing your taxable income through smart planning. Most landlords don't lose money because of Section 24 itself, they lose money because they don't adapt their strategy to the current tax environment. If you want to know which strategies truly make a difference for your specific situation and see 'BTL investment returns' improve, this is exactly what we analyse inside Property Legacy Education, helping you build a profitable portfolio even with these hurdles.

Steven's Take
For higher-rate taxpayers, Section 24 fundamentally changes how we approach BTL investments, moving from a profit-based tax system to an income-based one, especially with mortgage interest. When I started my portfolio, Section 24 wasn't yet established, so my initial calculations didn't factor in this change. However, as the rules solidified, I had to reassess. Simply put, for another BTL, if you're an individual landlord, you'll be taxed on your rental income before mortgage interest deductions, receiving only a 20% tax credit on those interest costs. This gap between your higher income tax rate (24% or 40%) and the 20% credit can significantly reduce true net profit. My strategy isn't about avoiding the tax, but managing the taxable income itself. This means rigorously tracking every legitimate allowable expense that isn't a finance cost. When budgeting for new acquisitions, I always factor in the maximum potential expenses upfront to get the most accurate picture of post-tax cash flow. It's about proactive expense management and understanding the difference between genuine 'repairs' and 'capital improvements' to prevent issues with HMRC. For instance, replacing windows with the same type is a repair, but upgrading single glazing to triple glazing might be considered an improvement. This level of detail has allowed my portfolio to remain robust even under the current regulations.
What You Can Do Next
Compile a detailed list of all non-finance allowable expenses annually to ensure no deduction is missed. Use HMRC guidance on PIM2060 for maintenance vs. improvement distinction.
Review your current property management strategy; if using an agent, ensure their fees are competitive, as these are deductible. Investigate whether any tasks can be self-managed without incurring costs, whilst maintaining service quality.
Obtain quotes for necessary repairs for any potential new BTL before purchase to estimate allowable expense deductions accurately. Differentiate these from capital improvements which do not provide annual income tax relief.
Consult with a specialist property accountant to clarify specific expense deductibility. This ensures you are fully optimising your claims and remaining compliant with current tax laws.
Evaluate insurance policies for your current and prospective BTLs. Ensure you have landlord insurance, as premiums are deductible, and compare providers for cost-effectiveness whilst maintaining appropriate coverage.
