Inheritance tax on rental property in the UK: how buy-to-lets are taxed

Published 22 October 2026 · Updated 22 October 2026

Inheritance tax on rental property in the UK works the same way as on any other asset: a buy-to-let counts towards the value of the estate, and Inheritance Tax is charged at 40% on the part of the estate above the tax-free threshold of £325,000 [1]. What makes rental property different is which reliefs apply, how it's valued with tenants in, and how the tax can be paid.

Add the market value of each rental property at the date of death to the rest of the estate, take off debts such as the mortgage, and compare the result with the £325,000 threshold [1][2]. The extra residence nil rate band is tied to the person's home passing to children or grandchildren, so a let property they never lived in won't normally bring it [3]. Anything left to a spouse or civil partner is exempt [1]. Tax is due by the end of the sixth month after the death, but tax on land and buildings, including let houses, can be paid in ten yearly instalments while they're not sold [4][5].

This is general information based on HMRC guidance and legislation, not tax advice. An estate with several properties should take professional advice.

Do you pay inheritance tax on a buy-to-let property?

Yes, if the estate as a whole is over the threshold. HMRC's checklist of assets to value includes "their home" and "any other properties, buildings or land" [2]. There's no separate exemption for property that's let to tenants.

The people who inherit don't normally pay the tax themselves. The executor pays it from the estate before the property is passed on [1][6]. HMRC will contact a beneficiary only in specific cases, for example where the personal representative couldn't or didn't pay [6].

The thresholds that matter

Allowance	Amount	Does a rental property qualify?
Nil rate band	£325,000	Yes, it applies to the whole estate [1]
Transferred nil rate band from a late spouse	Up to a further £325,000	Yes, whole estate [1]
Residence nil rate band	Can raise the threshold to £500,000 when a home goes to children or grandchildren; the maximum shown in HMRC's examples is £175,000	Only for a home, not a property that was only ever let [3][7]
Spouse or civil partner exemption	Unlimited	Yes, if the rental property is left to them [1]
Taper of residence band	Reduces by £1 for every £2 the estate is over £2 million	Applies to large portfolios [7]

GOV.UK's guidance on passing on a home says the threshold can increase to £500,000 if "you own your home (or a share in it)" and leave it to children or grandchildren, with an estate worth less than £2 million [3]. The extra band is about a home. If the person lived in one of the rental properties at some point, get advice on whether it can count; the rules on which residence qualifies are detailed.

For a landlord with a large portfolio, the taper matters too. HMRC's guidance says the residence nil rate band "will gradually reduce, or taper away, for an estate worth more than £2 million", at £1 for every £2 over [7].

How the rental property is valued

The value is what the property would sell for on the day of death [2]. You'll need a professional valuation for property in an estate that pays tax, and the value is later the starting point for Capital Gains Tax (see our probate valuation guide).

Joint ownership changes the figure:

If the person owned the property as joint tenants with a spouse or civil partner, divide the value by 2 [2].
If they owned it as joint tenants with others, such as siblings, divide by the number of owners and take 10% off the person's share [2].
If they owned it as tenants in common, value their actual share [2].

Debts you can deduct

Debts are not part of the initial estimate, but you must tell HMRC about them if you report the estate, and they reduce the taxable estate [2]. GOV.UK lists mortgages, loans, credit cards, household bills and unpaid bills for work done, such as building work [2]. For a buy-to-let landlord, unpaid bills for repairs or agents at the date of death count.

Worked example: inheritance tax on rental property

Margaret dies a widow, leaving everything to her two children. She lived in her own house and owned one buy-to-let flat. Her late husband left everything to her, so his nil rate band is unused. The figures below assume she qualifies for the full residence nil rate band on her own home and on transfer from her husband, and use the £175,000 maximum shown in HMRC's examples [7].

Item	Value
Her home	£400,000
Buy-to-let flat	£250,000
Savings	£50,000
Less buy-to-let mortgage	minus £100,000
Net estate	£600,000
Nil rate band, hers plus her husband's unused band	£650,000
Residence nil rate band, hers plus his	£350,000, capped at the home's value
Inheritance Tax	£0

Now take a single landlord with three let flats and no home of his own (he rented), leaving everything to his nephew:

Item	Value
Three flats	£750,000
Savings	£30,000
Less mortgages	minus £180,000
Net estate	£600,000
Nil rate band	£325,000
Residence nil rate band	£0 (no home, and a nephew is not a direct descendant) [3]
Taxable	£275,000
Inheritance Tax at 40%	£110,000 [1]

The same net estate gives very different results, mainly because of the home and who inherits it.

Paying inheritance tax on rental property: deadlines and instalments

Inheritance Tax must be paid by the end of the sixth month after the death. GOV.UK's example: if the person died in January, pay by 31 July [4]. You usually need to make a payment before probate is granted [4]. You'll need a payment reference at least 3 weeks before paying [4].

That creates a problem for property-rich estates: the money is tied up in houses that can't be sold until probate. Two features help.

Yearly instalments. You can pay tax on land and buildings in equal yearly instalments over 10 years. GOV.UK says this "applies even if you rent out the land or building and do not live there" [5]. The first instalment is due at the six-month date, and you'll usually pay interest on later instalments. If you sell the property, the rest becomes payable [5]. The legal basis is section 227 of the Inheritance Tax Act 1984 [8].

Direct Payment Scheme. Banks and building societies can pay HMRC from the deceased's accounts before probate [4].

If the estate must report full details, the IHT400 account must be sent within 12 months, and you can't apply for probate until you have [2].

If you sell the property for less than the probate value

If the estate sells land or buildings within three years of the death for less than the value at death, the appropriate person can claim to substitute the sale price, under section 191 of the Inheritance Tax Act 1984 [9]. The claim must be made within four years after the end of the three-year period [9]. It doesn't apply if the difference is less than the lower of £1,000 and 5% of the value [9].

Changing who inherits: deeds of variation

Within two years of the death, the people who benefit can vary the will in writing, and for Inheritance Tax the change is treated as if the person who died had made it, if the document includes a statement that they intend this [10]. For example, a child might redirect a rental flat to their own children. Take legal advice before signing one.

How to avoid inheritance tax on rental property (planning during life)

People search for this, so here are the rules GOV.UK sets out. They are not advice:

Gifts are free of Inheritance Tax if the giver lives seven more years; within seven years, taper relief can reduce the tax on gifts made three to seven years before death if total gifts exceed the threshold [11].
Giving away a property but still benefiting from it is a "gift with reservation" and counts in the estate [11].
Selling to a relative for less than market value counts the difference as a gift [11].
Gifting a let property can trigger Capital Gains Tax for the giver, because a gift is valued at market value [12].

How Gaffy fits in

Gaffy doesn't do tax returns. It keeps what the executor and accountant will ask for (tenancy agreements, rent records, certificates and repair history) in one vault, and reminds you before compliance dates while the estate is administered. £12 a month for up to 5 properties, plus £4 a month per extra property, first month free, and we'll set your properties up for you.

FAQ

Does rent received after death count for Inheritance Tax?

Rent received after the death is estate income, taxed under Income Tax rules [13]. Rent owed but unpaid at the date of death is an asset of the estate [2].

Is a property company's shareholding treated the same?

No. Shares are valued differently and may have other rules. Take advice.

What's the rate if 10% goes to charity?

The estate can pay 36% on some assets if 10% or more of the net value goes to charity [1].
