With Section 24 mortgage interest relief changes now fully in, how are BTL landlords realistically minimising their tax bill? Are SPVs the only option left or are there other legitimate strategies people are actually using for their existing properties?
Quick Answer
With Section 24 fully implemented since April 2020, individual landlords can no longer deduct mortgage interest, receiving only a 20% tax credit. Many mitigate this by transferring properties into a Limited Company (SPV) or considering furnished holiday lets.
## Handling Property Tax: Effective Strategies for BTL Landlords
Since April 2020, individual landlords can no longer deduct mortgage interest from their rental income, instead receiving a 20% basic rate tax credit on finance costs. This fundamental shift has made tax efficiency a primary concern, driving many investors to re-evaluate their structures and strategies.
### Is an SPV the Only Option for Tax Efficiency?
While a Special Purpose Vehicle (SPV), or limited company, is often highlighted as the most effective route for new buy-to-let purchases post-Section 24, it is not the *only* option. For properties acquired and held within an SPV, mortgage interest remains a deductible expense against rental income before Corporation Tax is applied. Corporation Tax rates are currently 19% for profits under £50k, 25% for profits over £250k, with marginal relief in between. This structure means that if a property is held in an SPV, the full finance cost can be offset against revenue, leaving a taxable profit. When profits are extracted, this usually happens via dividends, which are then subject to personal income tax. This can often be more tax-efficient than holding properties personally, especially for higher and additional rate taxpayers who would receive only a 20% tax credit on their finance costs if held personally. However, transferring existing properties into an SPV can trigger Stamp Duty Land Tax (SDLT) and Capital Gains Tax (CGT) liabilities, making this strategy complex and costly for an already established portfolio.
### Allowable Expenses: An Important Tax Minimisation Tool
Even with Section 24, landlords can significantly reduce their taxable income by ensuring all legitimate allowable expenses are claimed. These are costs wholly and exclusively incurred for the purpose of the rental business. Examples include:
* **Agent fees and professional services:** This covers letting agent fees, accountants, solicitors for leases, and property management fees. For instance, a £1,000 letting agent fee directly reduces taxable income by £1,000.
* **Repairs and maintenance:** Costs for things like re-roofing, boiler repairs, and decorating, provided they are not improvements. For example, replacing a broken boiler for £2,500 is allowable, but installing a new, more efficient heating system where one didn't exist might be treated differently.
* **Landlord insurance:** Building and contents insurance specific to the rental property. A £400 annual premium is deductible.
* **Legal and accountancy fees:** Costs associated with preparing tax returns, tenancy agreements, and resolving disputes.
* **Council Tax and utility bills (when empty):** If the property is vacant between tenancies, the landlord can deduct these costs until a new tenant moves in.
* **Travel expenses:** Reasonable costs for travelling to and from your rental properties. For example, fuel costs for inspecting a property.
Claiming all eligible expenses is fundamental for any landlord, irrespective of their tax structure, and can substantially lower the taxable rental profit.
### Capital Allowances and Other Strategies
Capital allowances permit landlords to claim tax relief on certain capital expenditures, even for residential properties. While limited for residential property, specific items like integral features (e.g., electrical systems, water heating) or plant and machinery in common parts of a multi-occupancy building might qualify. For example, if a landlord spends £5,000 on replacing a communal boiler in an HMO, a portion of this might be allowable as a capital allowance, reducing the taxable profit. Also, some landlords explore hybrid approaches, such as moving certain operational aspects of their property business into a limited company, while keeping the property ownership personal. This can involve setting up a management company to charge fees to the individual landlord, thus shifting some income and expenses into a corporate structure. However, this must be done on an arm's length basis and reflect commercial reality to be legitimate. Each strategy requires careful consideration and professional advice to ensure compliance and effectiveness.
## Property Tax Minimisation in Practice
* **Limited Company (SPV):** Allows full mortgage interest deductibility against rental income before Corporation Tax, which is currently 19% for profits under £50k. Example: An SPV with £20,000 rental profit and £8,000 interest costs pays tax on £12,000, leading to a £2,280 Corporation Tax bill (at 19%).
* **Comprehensive Expense Tracking:** Maximises deductions for legitimate costs like letting agent fees, repairs (not improvements), and landlord insurance. Example: Tracking £5,000 in allowable expenses on a property reduces your taxable income from £15,000 to £10,000.
* **Capital Allowances:** Enables tax relief on specific capital expenditures like integral features, reducing taxable profit. Example: Claiming £2,000 in capital allowances on a new heating system reduces taxable profit by £2,000.
## Pitfalls and Considerations
* **Illegal Expense Claims:** Claiming non-allowable or inflated expenses can lead to HMRC investigations, fines, and penalties. Be scrupulous in your record-keeping and only claim what is genuinely 'wholly and exclusively' for the business.
* **Transferring Existing Properties to an SPV:** This often triggers SDLT (at the additional dwelling surcharge rate of 5% on top of base rates) and CGT (18% or 24% for higher rate taxpayers) on the property's market value, which can outweigh the long-term tax benefits. A property purchased for £150,000 now worth £250,000 could incur CGT on a £100,000 gain, plus SDLT on £250,000 if transferred to an SPV.
* **Insufficient Record Keeping:** Without detailed and organised records, landlords cannot substantiate their expense claims, risking disallowance by HMRC. Maintain digital or physical copies of all invoices, receipts, and bank statements related to property expenses.
* **Ignoring Future Tax Changes:** New property income tax rates from April 2027 (basic rate 22%, higher rate 42%, additional rate 47%) will further impact personal landlords, making forward planning even more critical. Landlords must consider how these future changes could alter the relative benefits of personal versus corporate ownership.
## Investor Rule of Thumb
For new acquisitions, an SPV is generally the most tax-efficient structure for most BTL investors, especially higher-rate taxpayers, but for existing personal portfolios, a thorough review of allowable expenses, capital allowances, and potential hybrid structures is essential before considering a costly transfer.
## What This Means For You
Understanding the nuanced impact of Section 24 and other tax legislation is paramount for maintaining profitable property investments. Most landlords don't lose money because they ignore taxes entirely, but because they fail to understand the legitimate strategies available to them.

Steven's Take
The shift with Section 24 was a wake-up call for many, myself included. While the initial reaction was often panic, the reality is that the landscape simply changed, and we, as investors, must adapt. For me, new purchases always go into an SPV. It's not a silver bullet, but it's generally the most efficient for growth. For existing properties, however, I've seen too many investors rush into costly transfers without fully understanding the SDLT and CGT implications. Maximising every single allowable expense, no matter how small, adds up significantly. The key is meticulous record-keeping and professional advice to ensure you're compliant and genuinely optimising your position, rather than taking unnecessary risks. It's about smart business decisions, not just 'getting around' tax.
What You Can Do Next
Review your property ownership structure: Consult with a specialist property tax accountant to evaluate if your current personal ownership is still optimal for your long-term goals or if an SPV for new purchases, or a Section 162 Incorporation could be beneficial.
Perform a detailed allowable expenses audit: Compile a comprehensive list of all expenses related to your rental properties for the last tax year and compare it against HMRC's guidance on allowable expenses to ensure you are claiming everything legitimately possible. Refer to gov.uk/renting-out-a-property/paying-tax for HMRC guidance.
Investigate capital allowances opportunities: Ask your accountant about potential capital allowances for any significant expenditures on your properties, especially for integral features or common areas in HMOs, as these can provide tax relief where other expenses might not.
Consult on future changes: Discuss with your tax advisor how the new property income tax rates from April 2027 could impact your personal tax liability and long-term financial planning for your portfolio.
