Succession planning

Inheritance tax planning for landlords

A rental portfolio is usually taxed in full on death, at 40% above the nil-rate bands. With time and the right structure, much of that can be planned for, while you keep control and income.

Why landlords face a bigger bill

Many business owners pass their companies on with little or no inheritance tax, thanks to Business Relief. Landlords usually can't. The law excludes businesses that consist wholly or mainly of making or holding investments, and HMRC treats letting property as exactly that.

So a portfolio is normally in your estate at its full value, less mortgages:

Nil-rate band£325,000 per person
Residence nil-rate bandUp to £175,000, for a home passing to direct descendants
TaperResidence band reduced by £1 for every £2 above £2m
Rate above the bands40% (36% if 10% or more goes to charity)
Unused bandsTransferable to a surviving spouse or civil partner

The bands are frozen up to and including 2030/31. A portfolio that keeps growing in value pulls more of your estate into tax each year. Try our landlord inheritance tax calculator for an estimate.

EXAMPLE: A £3M PORTFOLIO IN ONE PERSON'S ESTATE£325kTaxable: about £2.68m × 40% ≈ £1.07m of inheritance taxThe nil-rate band is £325,000. The residence nil-rate band only applies to a home left to direct descendants, and tapers awayfor estates over £2m, so a large portfolio usually gets little or no benefit from it. Rental property is not usually business property.Gifts made more than seven years before death fall outside the estate. The earlier planning starts, the more it can save.
Inheritance tax on a property portfolio. Let property usually doesn't qualify for Business Relief, so a portfolio is normally exposed to inheritance tax at 40% above the available nil-rate bands. Planning in good time, through gifts, a Family Investment Company, trusts or insurance, can reduce the bill substantially. Illustration only. Covered by nil-rate bands Taxed at 40%

The planning tools

Lifetime gifts

Outright gifts fall outside your estate after seven years. But a gift of property is a disposal at market value for capital gains tax, so timing and choice of property matter. See passing property to your children.

Trusts

Trustees control the property for the family. Lifetime transfers above the nil-rate band are charged at 20%, so trusts are usually used within the band.

Insurance and liquidity

Life cover written in trust can provide the cash to pay the tax, so properties don't have to be sold in a hurry.

Mistakes we see

  • Giving a property away but keeping the rent or the use of it. That's a gift with reservation of benefit, and it stays in your estate.
  • Ignoring capital gains tax. A gift of a rental property is taxed as if you sold it at market value, and there's no holdover relief for ordinary let property.
  • Leaving it all to the second death. Leaving everything to a spouse defers the tax, but the combined estate can then be far above the taper threshold.
  • Forgetting pensions. From 6 April 2027 most unused pension funds come into the estate for inheritance tax, which can change the order in which you should spend your wealth.

How we help

FAQs

Frequently asked questions

Why is a rental business treated differently from a trading business for inheritance tax?

Business Relief isn't available where a business consists wholly or mainly of making or holding investments, or dealing in land or buildings. HMRC treats a property rental business as an investment business, even a large, actively managed one. That applies whether you own the properties personally, in a partnership or through a company. So a portfolio is normally taxed in full at 40% above the nil-rate bands, unlike a trading business.

Does the £2.5m Business Relief allowance help landlords?

Usually not. From 6 April 2026, 100% Business and Agricultural Property Relief is limited to the first £2.5m of qualifying property per person, with 50% relief above that. But the allowance only matters if the property qualifies in the first place, and let residential property normally doesn't. It can matter for landlords who also own a trading business, or for genuinely trading activities such as some hotels, where the rules need checking carefully.

How much of my estate is free of inheritance tax?

Everyone has a nil-rate band of £325,000. If you leave a home you've lived in to your children or grandchildren, a residence nil-rate band of up to £175,000 can be added. Unused bands pass to a surviving spouse or civil partner, so a married couple can have up to £1m between them. Above that, tax is charged at 40%. These bands are frozen up to and including 2030/31.

Can I keep the residence nil-rate band if I've let out my former home?

Potentially, yes. The residence nil-rate band applies to a property you lived in as your home at some point while you owned it, so a former home that you later let out can qualify, as long as it passes to your direct descendants. A buy-to-let you've never lived in can't. If there's more than one qualifying property, your executors choose which one to use, and the band is still tapered for estates over £2m.

How is inheritance tax charged on a portfolio my spouse and I own together?

Each estate includes your own share of the portfolio, less your share of the mortgages. If you own as tenants in common, you can leave your share to whoever you choose, such as your children, using your own nil-rate band on the first death. As joint tenants, your share passes automatically to your spouse. Anything passing to a spouse is usually exempt, but it builds up the estate taxed on the second death.

Do mortgages reduce inheritance tax on a property portfolio?

Generally yes. Mortgages secured on the properties are normally deducted from their value, so a highly geared portfolio has a lower taxable value than its gross worth suggests. There are rules that can restrict the deduction in some cases, for example where borrowing funds assets that are themselves exempt. As loans are repaid, the taxable value of the estate rises, which is worth bearing in mind when planning repayments.

How does taper relief work on a gift of property?

An outright gift to a person is a potentially exempt transfer. If you live seven years, it's outside your estate. If you die within seven years, it's added back and uses your nil-rate band first. Tax on the gift itself is reduced on a sliding scale if you die between three and seven years after it: 32%, 24%, 16% or 8% instead of 40%. Remember a gift of property can also trigger capital gains tax.

Can I give away surplus rent regularly without waiting seven years?

Yes, if they're genuinely regular, made out of your income rather than capital, and leave you with enough to keep your normal standard of living. Gifts that meet those tests are exempt straight away, with no seven-year wait and no upper limit. Surplus rental income can fund school fees, savings for grandchildren or premiums on a life policy in trust. Keep clear records of income, spending and gifts each year for your executors.

What happens to inheritance tax if a gifted property grows in value?

The growth belongs to the person you gave it to, and isn't added to your estate. If you die within seven years, it's the value at the date of the gift that's brought back into account, not the value at death. That's why giving away assets expected to grow, or putting future purchases into a family company owned by your children, can save more than giving away the same value in cash.

How much can a couple put into trust without an immediate tax charge?

Each person can usually transfer up to their available nil-rate band, £325,000, into a trust without the 20% lifetime charge, as long as they haven't made other chargeable transfers in the previous seven years. A couple who own property jointly can therefore each transfer value. Seven years later, each nil-rate band is available again. Capital gains, SDLT where there's a mortgage, and the trust's ongoing charges all need checking first.

Does a Family Investment Company reduce inheritance tax on property?

It can, mainly by moving future growth out of your estate. You fund the company, and your children hold shares that receive the growth while you keep control through voting shares. A loan you make to the company stays in your estate, but doesn't grow. Shares you give away are gifts that fall out after seven years. It's slower and more controlled than giving property away outright.

What kind of life cover suits inheritance tax on a property portfolio?

For a couple, a joint whole-of-life policy that pays out on the second death is common, because that's usually when the tax falls due. Written in a suitable trust, the payout isn't part of your estate and reaches your family quickly. A term policy can cover the seven years after a large gift. We work out the likely liability, and a regulated financial adviser arranges the cover.

Will my unused pension count towards inheritance tax from 2027?

From 6 April 2027, most unused pension funds and death benefits will count as part of your estate for inheritance tax. Personal representatives will be responsible for reporting and paying the tax. Death-in-service benefits and dependants' scheme pensions are excluded. Landlords who planned to leave their pension untouched and spend other assets first may want to look again at the order in which they draw on their wealth.

Is there inheritance tax when I leave my portfolio to my spouse?

Usually no. Assets left to a spouse or civil partner are normally exempt, and the unused nil-rate band passes to them. But that only delays the tax. On the second death, the whole combined portfolio is in one estate, often well above the £2m taper threshold. Planning often works best while both of you are alive, using both sets of allowances and the seven-year clock.

How is inheritance tax paid if the estate is mostly property?

Executors usually need to pay at least some inheritance tax before probate is granted, which is difficult when the estate is mainly properties that can't be sold yet. Tax on land and buildings can usually be paid in ten yearly instalments, with interest on the balance, but it becomes due in full once a property is sold. Life cover, cash reserves or lender facilities can all help. Planning ahead avoids forced sales at the wrong time.

Should I leave my portfolio to my grandchildren rather than my children?

It can make sense if your children are already well provided for. Property left to children is likely to be taxed again when they die, so leaving some directly to grandchildren, or to a trust for them, can skip one round of inheritance tax. Grandchildren also count as direct descendants for the residence nil-rate band. If grandchildren are young, a trust is usually needed so the properties can be managed for them.
