Inheritance Tax on Buy-to-Let Property (2026/27)
Last updated 23 June 2026 · 11 min read · By the LandlordTaxAi Editorial Team
The short answer
A buy-to-let portfolio is taxed at 40% Inheritance Tax on its value above your nil-rate bands — £325,000 each, plus up to £175,000 residence band that only covers your own home, not your rentals. Critically, letting property does not get Business Relief, so it is fully exposed. Lifetime gifts, trusts and the 7-year rule are the main planning tools.
Many landlords spend years optimising income tax and Capital Gains Tax, then leave their families a 40% Inheritance Tax bill on the whole portfolio. Because letting is treated as an investment rather than a trade, the reliefs that protect genuine businesses simply do not apply. This guide explains exactly how exposed a buy-to-let estate is, the band that catches people out, and the levers you can pull. To estimate your own position, use our Inheritance Tax calculator.
The bands for 2026/27
| Allowance | Amount | Applies to buy-to-let? |
|---|---|---|
| Nil-rate band | £325,000 | Yes |
| Residence nil-rate band | up to £175,000 | No — only your own home to descendants |
| Rate above the bands | 40% | Yes |
| Business Relief on a let portfolio | None | Investment, not a trade |
Both nil-rate bands are frozen until April 2030. With property values rising and the thresholds standing still, more landlord estates are dragged into Inheritance Tax every year — a quiet form of fiscal drag.

Margaret, a widow, owns a home worth £400,000 and three buy-to-lets worth £750,000 in total, with £100,000 of savings. She leaves everything to her two children. She also inherited her late husband’s unused nil-rate bands.
| Total estate | £1,250,000 |
| Less: nil-rate bands (2 × £325,000) | − £650,000 |
| Less: residence bands (2 × £175,000, home to children) | − £350,000 |
| Taxable estate | £250,000 |
| Inheritance Tax at 40% | £100,000 |
Even with both spouses’ bands and the residence band on her home, Margaret’s estate still owes £100,000 — almost entirely because the £750,000 of buy-to-let gets no shelter beyond the basic nil-rate bands. Had she held no property at all, the same £1.25m of cash would actually be taxed more, because the residence band needs a home — but the point stands: the rentals drive the bill.
Ways to reduce the bill
Lifetime gifts
Give property or cash away and survive seven years and it leaves your estate — but a gift of property is a Capital Gains Tax disposal, so model both taxes together.
Trusts and companies
Holding property in a trust or company can make it easier to pass value down gradually, though each has its own tax cost and complexity.
Life insurance in trust
A whole-of-life policy written in trust pays out free of Inheritance Tax and gives your family the cash to settle the bill without a forced sale.
Frequently asked questions
Do you pay Inheritance Tax on buy-to-let property?
Yes. Buy-to-let and second homes form part of your estate and are taxed at 40% Inheritance Tax on the value above your available nil-rate bands. Unlike a genuine trading business, a property-letting portfolio is treated as an investment, so it does not qualify for Business Relief. That means a landlord's portfolio is often the largest single source of an Inheritance Tax bill.
What are the nil-rate bands for 2026/27?
Everyone has a nil-rate band of £325,000, taxed at 0%. There is also a residence nil-rate band of up to £175,000, but only when you pass your own home to direct descendants such as children or grandchildren. Both bands are frozen until April 2030. A married couple or civil partners can combine their bands, potentially sheltering up to £1 million — but the residence band only applies to your home, never to a buy-to-let.
Does the residence nil-rate band apply to buy-to-let?
No. The £175,000 residence nil-rate band only applies to a property you have lived in as your home and which passes to direct descendants. A buy-to-let or a second home you never lived in does not qualify. This is a common and expensive misunderstanding — landlords often assume the residence band shelters all their property, when it only covers their actual home.
How can landlords reduce Inheritance Tax on a portfolio?
Options include making lifetime gifts (which fall out of your estate if you survive seven years), using trusts, holding property through a company to pass shares gradually, taking out life insurance written in trust to cover the bill, and making use of both spouses' nil-rate bands. Each has trade-offs — gifts can trigger Capital Gains Tax, and trusts have their own charges — so portfolio Inheritance Tax planning should always be done with a qualified adviser.
What is the 7-year rule on gifts?
If you give an asset away and survive seven years, it normally falls out of your estate entirely for Inheritance Tax. If you die within seven years, the gift is brought back into the calculation, though taper relief can reduce the tax on gifts made between three and seven years before death. Gifting property also has Capital Gains Tax consequences, because a gift is treated as a disposal at market value.
