Who actually pays the inheritance tax?
This is the single most misunderstood point about inheritance tax (IHT) and shared property. When a co-owner dies, IHT is not a bill that lands on the surviving owner. It is a tax on the deceased person's estate - the total of everything they owned, including their share of the property. The executors (in Scotland, the executor-nominate or executor-dative) calculate the estate's value, work out any IHT, and pay it from the estate before passing on what remains.
So if you co-own a home with someone who has died and you are worried a tax demand will arrive addressed to you, it will not. What can happen is that the deceased's share carries an IHT liability that the estate must fund - and if the estate is short of cash, that can create pressure to sell the property to raise the money. That is the practical link between IHT and a property sale, and it is why owners in this position often look at their sale options early.
How joint property ownership works in Scotland
Scotland does not use the English terms joint tenants and tenants in common. Instead, co-owners hold property pro indiviso - each owning a defined share (often one-half each). What happens to a deceased owner's share depends on whether the title contains a survivorship destination.
| Feature | With a survivorship destination | Without a survivorship destination |
|---|---|---|
| What happens to the share on death | Passes automatically to the surviving co-owner | Passes under the will, or by intestacy rules |
| Goes through the estate? | Passes outside the will, but is still counted for IHT | Yes - forms part of the estate to be administered |
| Can the owner leave the share to someone else? | No - the destination overrides the will for that share | Yes - free to leave the share to anyone |
| Still counted for inheritance tax? | Yes - the value is still in the IHT calculation | Yes |
The key thing to understand is that a survivorship destination changes who receives the share, but it does not remove that share from the inheritance tax calculation. The value of the deceased's half still counts towards the estate for IHT, even though it passes automatically to the survivor. If you are dealing with an inherited share, our guide to selling inherited property explains the wider process.
The 2026/27 thresholds - when is any tax actually due?
Most estates pay no inheritance tax at all, because of the tax-free allowances. IHT is charged at 40% only on the value above the available thresholds. For the 2026/27 tax year the figures are frozen at the levels below - a freeze the UK Government has now extended to April 2031, which quietly pulls more estates into the net as property values rise.
| Allowance (2026/27) | Amount per person | What it applies to |
|---|---|---|
| Nil-rate band (NRB) | £325,000 | Any assets in the estate |
| Residence nil-rate band (RNRB) | £175,000 | A home left to children or other direct descendants |
| Combined per person | Up to £500,000 | Where the RNRB conditions are met |
| Combined for a married couple / civil partners | Up to £1,000,000 | Unused allowances transfer to the survivor |
Two rules matter for co-owned homes. First, the residence nil-rate band only applies where the home passes to direct descendants (children, grandchildren and so on), and it tapers away for estates above £2 million - reduced by £1 for every £2 over that line. Second, a married couple or civil partners can transfer any unused NRB and RNRB to the survivor, which is how a couple can reach the widely quoted £1 million tax-free figure. These are HMRC rules that apply UK-wide, including in Scotland.
The spouse and civil partner exemption
This is the exemption that removes IHT for most couples who own a home together. Transfers between spouses or civil partners are completely exempt from inheritance tax. So when one co-owning spouse dies and their share passes to the other - whether by a survivorship destination, by will or by the rules of intestacy - there is normally no IHT to pay on that transfer at all, regardless of the value. The tax question is deferred until the second death, when the combined allowances (potentially up to £1 million) are available.
The picture is different for unmarried co-owners - cohabiting partners, siblings, friends or a parent and adult child who own together. There is no spouse exemption between them, so the deceased's share is assessed against their own nil-rate bands, and IHT can be due if the estate is large enough. This is a common trap for cohabiting couples in Scotland, who do not get the spouse exemption no matter how long they have lived together.
Worked scenarios: who pays, and how much
| Situation | Is IHT likely? | Who settles it |
|---|---|---|
| Married couple, home passes to survivor | No - spouse exemption applies | N/A on first death |
| Cohabiting couple, deceased's share to partner | Possibly - assessed against the £325k NRB | The deceased's estate |
| Parent and adult child co-own; parent dies | Possibly - depends on total estate value | The parent's estate |
| Two siblings co-own an inherited house | Possibly - each share sits in that owner's estate | The deceased sibling's estate |
| Sole owner leaves home to children | Only above £325k + £175k (up to £500k) | The estate |
Key takeaways
- IHT on a jointly owned property is paid by the deceased owner's estate, not by the surviving co-owner personally.
- In Scotland co-owners hold pro indiviso shares; a survivorship destination changes who inherits but not the IHT calculation.
- For 2026/27 the nil-rate band is £325,000 and the residence nil-rate band £175,000, both frozen to April 2031.
- Transfers to a spouse or civil partner are exempt, so most married couples pay no IHT on the first death.
- Cohabiting partners get no spouse exemption - a common and costly trap.
- If the estate lacks cash to pay the IHT, selling the property quickly can be the practical solution.
How much inheritance tax would be due?
The calculation is: take the value of the deceased's share of the property, add it to everything else in their estate, subtract debts and any available allowances, and charge 40% on what is left. On a jointly owned home there is one useful discount worth knowing about - HMRC often accepts a reduction (commonly around 10-15%) on the value of a part-share of a property, to reflect that a half-share of a house is harder to sell than a whole one. Your solicitor or a valuer will advise on whether it applies and at what level, because it depends on who the co-owner is.
When is inheritance tax due, and what if there is no cash?
Inheritance tax is generally due within six months of the end of the month in which the person died, and interest runs on anything paid late. That deadline is what turns an IHT liability into a reason to sell. Where the estate is mostly tied up in the property and there is little cash, executors can face a squeeze: the tax is due, but the money is locked in bricks and mortar. HMRC does allow IHT on property to be paid in annual instalments over up to ten years, but interest applies and the balance usually falls due when the property is sold. For many families the cleaner answer is to sell the property, clear the tax, and distribute what remains. Our guide on selling a house before probate (and the Scottish equivalent, Confirmation) explains the timing.
Who this affects most
The people who most need to plan for this are unmarried co-owners and beneficiaries of larger estates. A cohabiting couple who bought together but never married, two siblings who inherited the family home, or a parent and child who own jointly all fall outside the spouse exemption, so a death can trigger a real IHT bill on the deceased's share. Add in frozen thresholds and rising property values, and estates that were comfortably below the limit a decade ago are now edging over it. If that is your situation, getting an accurate valuation of the share and the whole estate early is the single most useful step.
Alternatives to selling the property
Selling is not the only way to fund an IHT bill. Executors can use other estate assets - savings, investments or life insurance written in trust - to pay the tax and keep the property. Where the beneficiaries want to retain the home, they may pay the IHT from their own funds, or use the ten-year instalment option, accepting the interest cost. Some families take out life insurance in advance specifically to cover an expected IHT liability. But where the estate is asset-rich and cash-poor, or where the beneficiaries do not want to keep the property, a sale is usually the simplest route - and speed matters because of the six-month deadline.
Risks and things to check
The main risks are missing the payment deadline and mis-valuing the share. Interest accrues on late IHT, so executors should establish the liability early rather than discovering it near the deadline. Get a proper valuation of the deceased's share, not a guess, and check whether the part-share discount applies. Confirm whether a survivorship destination exists on the title, because it determines who inherits and can override the will. And take advice on the residence nil-rate band conditions, which are easy to lose if the home does not pass to direct descendants. On anything beyond a straightforward married-couple situation, a solicitor's advice on the specific figures is essential - our guide on whether you need a solicitor to sell in Scotland is a useful starting point.
How auction helps when IHT creates a deadline
When inheritance tax is due within six months and the money is tied up in the property, the open market can be too slow and too uncertain - a listing that drags on, or a buyer who pulls out, can push executors past the deadline and into interest charges. Selling by auction addresses exactly that. The property is put in front of our more than 11,000 registered buyers, and when a bid succeeds the buyer commits immediately with a non-refundable deposit under our SaleLock Guarantee. The sale is binding, completion is typically within 28 days, and it runs on a no-sale-no-fee basis - giving executors a firm date by which the tax can be paid and the estate settled.

The bottom line
Inheritance tax on a jointly owned property is paid by the deceased owner's estate, not by the surviving co-owner. For married couples and civil partners the spouse exemption usually means no tax on the first death; for everyone else, the deceased's share is assessed against the £325,000 nil-rate band (plus up to £175,000 for a home left to descendants). The pressure point is the six-month payment deadline when the estate has little cash - and that is when a fast, binding sale of the property becomes the practical answer.
