Definition
Rental income is the money you receive from letting out a property to tenants, including rent payments, service charges, and any deposits retained for damage or unpaid bills.
Understanding rental income is essential for landlords creating wills, as it affects both lifetime tax planning and how your estate is managed after death.
What Does Rental Income Mean?
Under UK law, rental income is governed by the Income Tax (Trading and Other Income) Act 2005, which defines it as all payments received from property tenants. This includes monthly rent, additional service fees for cleaning or maintenance, non-refundable deposits kept due to damage or unpaid rent, and reimbursements for utilities or council tax paid on behalf of tenants. The legislation applies to furnished and unfurnished properties, buy-to-let investments, second homes, and commercial premises.
The first £1,000 of rental income annually is tax-free under the Property Income Allowance, introduced in 2017. Beyond this threshold, you must report rental income to HMRC on a Self Assessment tax return. You face a choice: claim the £1,000 allowance or deduct actual expenses—not both. Most landlords with significant expenses benefit more from deducting actual costs like insurance, agent fees, repairs, and maintenance rather than taking the flat £1,000 allowance.
Tax rates on rental income depend on your total income. Rental profits are added to your other income and taxed at your marginal rate: 20% for basic-rate taxpayers, 40% for higher-rate, or 45% for additional-rate. Since April 2020, mortgage interest relief has been restricted to a 20% tax credit rather than a full deduction, significantly increasing tax bills for highly-mortgaged landlords. Sarah rents out a two-bedroom flat in Manchester for £950 monthly (£11,400 yearly). After deducting £3,200 in allowable expenses, her taxable profit is £8,200. As a higher-rate taxpayer, she pays £3,280 in tax (40% of £8,200).
HMRC's Connect system cross-references data from the Land Registry, tenancy deposit schemes, letting agents, local councils, and banks to detect undeclared rental income. Even small landlords with single properties are routinely identified. Penalties for non-disclosure range from 30% for careless mistakes to 100% for deliberate concealment, plus interest on unpaid tax. The Let Property Campaign allows landlords to voluntarily disclose previously undeclared income with potentially reduced penalties.
Rental income has significant estate planning implications. Unlike some business assets, residential rental properties do not qualify for Business Property Relief for inheritance tax purposes. Properties are valued at market rate (or potentially lower if sitting tenants reduce value) when calculating inheritance tax. The rental income itself doesn't directly increase estate value, but accumulated income you haven't spent becomes cash assets subject to inheritance tax if your estate exceeds the nil-rate band.
When a landlord dies, rental income continues during probate. The executor must collect this income, use it to pay ongoing expenses like mortgages and maintenance, report it to HMRC as estate income, and eventually distribute remaining funds to beneficiaries. Emma, executor of her father's estate, collected £9,600 in rent over eight months of probate. She used this to pay the £650 monthly mortgage and £350 monthly maintenance costs, reported the estate income to HMRC, paid estate income tax, and distributed the remaining £1,820 to beneficiaries after probate completed.
Common Questions
"Do I need to declare rental income to HMRC if I only earn a small amount?" Yes, you must declare rental income if your total UK property income exceeds £1,000 per year (before expenses), or £2,500 after deducting rental expenses. The first £1,000 is covered by the Property Income Allowance, making it tax-free, but you still need to report income above these thresholds on a Self Assessment tax return.
"What happens to rental income when someone dies and the property is in their estate?" Rental income continues to be collected by the executor during probate and must be reported to HMRC as estate income. The executor uses this income to pay ongoing property expenses (mortgage, maintenance, utilities), settle inheritance tax and debts, and eventually distribute remaining funds to beneficiaries once probate completes.
"Can rental income affect the value of my estate for inheritance tax purposes?" Rental income itself doesn't directly increase your estate value, but the accumulated income you haven't spent becomes part of your cash assets. The rental property's market value (not its income) determines the inheritance tax liability. However, properties with sitting tenants may be valued lower than vacant properties when calculating your estate.
Common Misconceptions
Myth: "HMRC won't notice if I don't declare rental income from just one property or small amounts."
Reality: HMRC's Connect system automatically cross-references data from the Land Registry, tenancy deposit schemes, letting agents, local councils, and bank records. Even small landlords are detected. Penalties range from 30% (careless mistakes) to 100% (deliberate concealment) of unpaid tax, plus interest. The introduction of automated data-matching in recent years has dramatically increased detection rates.
Myth: "The £1,000 Property Income Allowance means I don't pay tax on my first £1,000 of profit."
Reality: The £1,000 allowance applies to gross rental income, not profit. If you receive £12,000 rent annually, you pay tax on £11,000 (not £12,000 minus expenses minus £1,000). You must choose: claim the £1,000 allowance OR deduct actual expenses—not both. Most landlords with significant expenses benefit more from deducting actual costs. This is one of the most common errors on Self Assessment returns.
