Relief for post-letting expenses

All good things come to an end, and a property rental business is no exception. However, expenses may be incurred in relation to that property rental business after it has ceased. Where this is the case, it may be possible to claim tax relief on those post-letting expenses. Understanding what qualifies—and how to claim it—can make a significant difference to your tax liability when you finally exit the buy-to-let market.

What are post-letting expenses?

Post-letting expenses are costs you incur after you’ve stopped letting a property but before you dispose of it entirely. They’re distinct from ordinary letting expenses (like maintenance, insurance, or mortgage interest during the letting period), which are deductible in the usual way.

Common examples include:

• Repairs or redecoration to prepare the property for sale
• Estate agent fees to market the property for sale
• Advertising costs
• Surveyor’s fees or valuations
• Legal fees related to selling
• Stamp Duty Land Tax (SDLT) incurred on the sale
• Capital Gains Tax (CGT) costs (though these are treated differently)

These expenses are incurred after the letting period ends but before you complete the sale. That timing is crucial for tax purposes.

The relief available under Section 24, Income Tax Act 2007

The main relief for post-letting expenses comes under Section 24 of the Income Tax Act 2007. HMRC allows you to deduct qualifying expenses incurred during the period between ceasing to let a property and disposing of it—provided the property is still held as a capital asset.

The relief is straightforward: you claim the cost against the rental income from that property in your Self Assessment tax return. This reduces your total taxable rental profit for the year.

It’s important to note that this relief applies only to revenue expenses—costs of a revenue nature—not capital expenses. For instance, a complete new roof is likely capital (improving the property’s value), whereas fixing a few loose tiles is revenue (repair and maintenance). HMRC’s distinction between repairs and improvements can be nuanced, so it’s worth careful consideration if you’re in any doubt.

Calculating your relief and reporting it

When you claim post-letting expenses on your Self Assessment return, you’ll report them in the Property Income section. If you’re a sole trader or in a partnership, you’ll use the supplementary pages for UK land and property income (SA105). If you operate via a company, the corporation tax return (CT600) and accounts will reflect the deduction.

The relief reduces your assessable rental profit for the year in which the expense was incurred. Since the 2017/18 tax year, landlords have faced restrictions on mortgage interest relief (claimed at the basic rate of 20% rather than at their marginal rate), but post-letting expenses fall outside this restriction and remain fully deductible.

If your post-letting expenses exceed rental income for the year (perhaps the property was let for only part of the year), you may create a loss. Losses can usually be carried forward to offset future rental income, or in some cases carried back. However, once the property is sold, you cannot carry forward unused losses.

What expenses are not relieved

Bear in mind that certain costs won’t qualify:

• Capital improvements (fitting a new kitchen, rewiring, structural work)
• Costs of selling that are capital in nature—for example, the portion of an estate agent’s fee that relates to finding a buyer (though fees for holding open house, marketing, etc., may be deductible)
• Your own time or labour
• Expenses incurred after completion of the sale (once the property is no longer yours)

Additionally, CGT-related costs are treated separately. Costs directly incurred in calculating or defending your CGT liability are allowed as deductions from the capital gain itself, not as income relief. This includes professional fees for CGT advice.

Planning ahead

If you’re considering exiting the buy-to-let market, it pays to be strategic about the timing and nature of expenses. Preparing the property for sale in the year before cessation of letting—rather than after—ensures those costs are deductible as letting expenses, avoiding any ambiguity.

Keep detailed records of all invoices, quotes, and receipts. This evidence is essential if HMRC enquires into your return, particularly when distinguishing repairs from improvements.

Next steps

Post-letting expense relief is a genuine allowance, but the detail matters. Whether you’re planning to sell, have recently ceased letting a property, or need to finalise your accounts, getting the treatment right is important.
