Inheritance Tax on Property Explained

For the great majority of families who face an inheritance tax bill, the culprit is the family home. Decades of rising house prices have quietly lifted ordinary homes above the tax-free thresholds, so that people who never thought of themselves as wealthy find their estates in the 40% net, driven almost entirely by the value of bricks and mortar. Understanding how property is taxed is therefore the natural starting point for most estate planning.

This guide explains how your home and any other property are treated for inheritance tax, the valuable residence nil-rate band, the pitfalls of giving your home away, and the practical question of how a bill secured on an illiquid asset actually gets paid. For the broader framework, read it alongside our complete guide to inheritance tax planning.

How property is taxed

Property is treated like any other asset in your estate: its open-market value at the date of death is added to everything else you own, savings, investments, possessions, and inheritance tax is charged at 40% on the total above your available allowances. Everyone has a nil-rate band of £325,000, frozen until 2030, and the value of your home counts fully towards the total.

The reason property looms so large is simply arithmetic. A home worth £500,000 already exceeds the standard nil-rate band on its own, before a penny of savings is counted. Where the standard allowances are all that apply, an estate of that size could face a five- or six-figure tax bill largely because of the house. This is precisely why the government created an additional allowance aimed squarely at the family home.

Valuation matters more than people assume. The figure used is the open-market value at the date of death, what the property would fetch on an ordinary sale, and for larger or unusual estates HMRC may expect a professional valuation rather than an estate agent’s estimate. Where a property is jointly owned, only the deceased’s share is counted, and a modest discount sometimes applies to a part-share that would be hard to sell on its own. Getting the valuation right protects the estate from both an unexpected bill and a later challenge, which is one reason executors often take professional help.

The residence nil-rate band

The residence nil-rate band is an extra slice of tax-free allowance, up to £175,000 in 2026, that applies when you leave your main residence to a direct descendant: a child, stepchild, adopted child, foster child or grandchild. Stacked on top of the standard £325,000, it lifts an individual’s total allowance to as much as £500,000 where a home is involved.

Because both allowances pass between spouses and civil partners, a married couple or civil partners can combine them to shelter up to £1 million, two lots of £325,000 plus two lots of £175,000, provided a home passes to their children. It is this combination that keeps many family estates out of inheritance tax altogether. Our note on the inheritance tax threshold works through exactly how the bands stack.

Passing the main home to children

The residence nil-rate band comes with conditions. It applies only to a property that has been your residence at some point, not a pure buy-to-let, and only where it passes to direct descendants. Leaving your home to a sibling, a niece or a friend does not qualify, and nor does leaving it into most kinds of trust, though there are exceptions for certain trusts for children.

There is also a valuable protection for those who downsize or sell up. If you move to a smaller home or into care and later die, a “downsizing addition” can preserve the residence nil-rate band you would have had, so you are not penalised for moving to a more manageable property in later life. The rules are fiddly, and getting your will right so the home genuinely passes to descendants is essential, a point our guide to reducing inheritance tax legally returns to.

Giving your home away

A tempting idea is to give the family home to the children now, so it falls out of the estate after seven years. In practice this is one of the most common and expensive mistakes in estate planning, because of the gift-with-reservation rules. If you give the house away but carry on living in it without paying a full market rent, HMRC treats it as still yours, and nothing has been achieved for inheritance tax.

Beyond the reservation trap, giving away your home surrenders the capital gains tax uplift that applies on death, potentially landing your children with a bill when they eventually sell. It also means losing control of the roof over your head, a serious risk if circumstances change. For most people, keeping the home and planning around it is safer than giving it away, and this is exactly the kind of decision to test with a regulated adviser.

Second homes and buy-to-let

Additional properties, a holiday home, a buy-to-let, an inherited flat, sit fully within your estate and do not attract the residence nil-rate band, since that applies only to a home you have lived in. A portfolio of rental property can therefore create a substantial inheritance tax exposure, taxed at 40% on top of the income tax and capital gains tax that already apply during your lifetime.

Landlords with several properties often find that their estate is asset-rich but cash-poor, which makes the eventual bill harder to settle. This is where planning tools, gifting, trusts, life cover and sometimes company structures, come into play, though each has trade-offs. Our inheritance tax planning hub and a specialist adviser can help weigh them against your wider goals.

A common instinct is to gift a second home to children while keeping the main residence. This can work, since a property you have never lived in is not caught by the gift-with-reservation rules in the same way, provided you take no benefit from it afterwards. But it is not free of complications: giving away a rental property is a disposal for capital gains tax, so you may face a bill on the gain to date even though no money changes hands, and the gift then starts its own seven-year clock. As ever, the interaction of the taxes means these moves are best modelled in full before you act, rather than assumed to be straightforward.

Paying a bill on an illiquid asset

Property creates a particular headache: the tax is due, broadly, within six months of death, but you cannot pay HMRC with a spare bedroom. Inheritance tax on property can be paid in ten annual instalments, which eases the pressure, but interest is charged on the outstanding balance, and the debt does not disappear.

Executors typically have a few options: pay the tax from other assets in the estate, sell the property, or use the instalment route while the family decides what to do. Many families plan ahead by taking out a life insurance policy written in trust, so a tax-free lump sum is available to settle the bill without forcing a rushed sale of a much-loved home. That approach turns an unpredictable liability into a funded, orderly one.

The cash-flow squeeze is more than a technicality. Because probate, the legal authority to deal with the estate, generally cannot be granted until at least some of the inheritance tax is paid, families can find themselves needing to raise money before they are legally able to sell the very property that creates the bill. Banks will sometimes release funds from the deceased’s accounts directly to HMRC, and specialist executor loans exist, but both take time and can add cost. Planning the funding in advance spares your family that stress at the worst possible moment.

Reducing the property tax burden

There is no single trick that makes property tax vanish, but several measures, used together, can materially reduce the burden, and often the best of them start with making full use of the allowances you already have.

• Make sure your will leaves the home to direct descendants so the residence nil-rate band is captured in full.
• Combine both partners’ allowances by planning as a couple, aiming to shelter up to £1 million.
• Consider life insurance written in trust to provide the cash to pay the bill without selling the property.
• Use lifetime gifting from other assets to bring a large estate below the £2 million taper threshold.
• Keep the home in your estate to preserve the capital gains tax uplift, rather than giving it away and losing it.

Property is emotive as well as valuable, and the wrong move, giving the house away, or leaving it to the wrong person in a will, can cost far more than it saves.
