Related Property, Valuation Rules and Quick Succession Relief in IHT

Updated 11 October 2026 · Fact-checked

IHT values a transfer by the loss to the donor: the fall in the value of their estate, not what the recipient gains. Related property (a spouse's assets and certain charity holdings) is valued together, then apportioned. Quoted shares use the lower of two measures. Quick succession relief then cuts death tax on recently inherited wealth.

Understand Valuation Rules, Related Property and Quick Succession Relief

Inheritance tax is charged on a transfer of value. The amount is found by the loss to donor principle. You value the donor's estate immediately before the transfer, then immediately after it. The difference is the transfer of value. It does not matter what the recipient receives. This matters when a gift causes a big drop in value, such as giving away shares that carry control.

Related property changes the 'before' and 'after' figures. Property owned by the transferor's spouse or civil partner is related. So is property held by a charity or other exempt body, if it came from the transferor or their spouse by an exempt transfer (after 15 March 1983) and the body either still holds it at the date of transfer or held it within the previous five years. The five years refers to how recently the body held the property, not to when the gift was made. You value the related property as one combined holding. Then you take the transferor's share of that combined value, in proportion to the values of the separate holdings or the number of shares. Combined holdings are often worth more than the parts, for example when 30% plus 25% gives a controlling 55%.

Quoted shares are valued from the stock exchange prices on the date of transfer. You take the lower of two figures. The first is the lower quoted price plus one quarter of the gap between the lower and higher quoted prices (the 'quarter up' value). The second is the average of the highest and lowest recorded bargains on that day. Unquoted shares are valued at the price a hypothetical open-market buyer would pay, and the exam gives you that figure.

Quick succession relief (QSR) is a relief against tax. It applies when a person's estate was increased by a chargeable transfer, and that person then makes a chargeable transfer or dies within five years. The relief is a percentage of the tax paid on the earlier transfer. The percentage falls as the gap grows. Fall in value relief applies to gifts that become chargeable because the donor died within seven years. If the gifted asset is worth less at death (or when the donee sold it in an arm's length sale), the value taxed is reduced by the fall.

Key rules to remember

Loss to donor: Transfer of value = value of estate before − value of estate after; For a chargeable lifetime transfer where the donor pays the IHT, the tax paid is also a loss to the estate, so gross up the net gift: gross = net ÷ (1 − 20%) = net ÷ 0.8 for the part above the nil rate band.
Related property apportionment: Transferor's value = (value of own holding ÷ combined value of related holdings) × value of combined holding; Use the number of shares or the separate stand-alone values as the apportioning base. Related property: spouse or civil partner, or an exempt body (such as a charity) that received the property from the transferor or spouse by an exempt transfer and either still holds it at the transfer date or held it within the previous 5 years.
Quoted shares: Lower of: (1) lower price + ¼ × (higher price − lower price); (2) ½ × (highest + lowest marked bargain); Use the prices on the date of transfer, which is the date of the gift or the date of death.
Quick succession relief: QSR = % × IHT on earlier transfer × (net increase to estate ÷ gross earlier transfer); Percentage by time from earlier transfer to later transfer or death: up to 1 year 100%; 1 to 2 years 80%; 2 to 3 years 60%; 3 to 4 years 40%; 4 to 5 years 20%. Learn this scale, as it is not in the tax tables. It reduces the tax, not the value.
IHT rates and nil rate band: Nil rate band £325,000; lifetime rate 20%; death rate 40%; Taper relief on lifetime gifts after death: over 3 but under 4 years 20%; over 4 but under 5 years 40%; over 5 but under 6 years 60%; over 6 but under 7 years 80%. It reduces the tax, not the value.
Fall in value relief: Value of gift for the tax on that gift = original value of gift − fall in value to death (or earlier arm's length sale); The relief reduces the value of the gift used to calculate the tax on that gift. The original value is still used when cumulating for later transfers and for working out the nil rate band left for them.

How to solve Valuation Rules, Related Property and Quick Succession Relief questions

Use this order for any question on valuing a transfer or on these reliefs.

1Identify the date and the type of transfer: a PET, a chargeable lifetime transfer (CLT) or the death estate. This sets the valuation date and the rates.
2List the assets. Flag any shares or land that a spouse, civil partner or a charity-type body also holds. These are related property.
3Value the estate before the transfer, using the combined value for related property and apportioning to the transferor. Use the lower-of-two rule for quoted shares.
4Value the estate after the transfer in the same way, then find the loss to donor. For a CLT where the donor pays the tax, gross up the net gift.
5Deduct exemptions, such as the annual exemption of £3,000, against the transfer in date order.
6If the gift is now chargeable on death and the asset has fallen in value, apply fall in value relief. It reduces the value of the gift used to calculate the tax on that gift. Keep the original value for cumulation on later transfers. Then calculate the tax using the nil rate band, the lifetime or death rate, and any taper relief.
7On death, check whether the deceased received a chargeable transfer in the previous five years. If so, calculate QSR and deduct it from the tax.
8State your assumptions and add a short conclusion, such as the extra tax or the saving.

Quickest way: Fast route for valuation and relief questions

When to use it: Use this when you have limited time in Section A or B and the question gives several holdings, a share price range and a death within five years of a gift.

Scan for spouse, civil partner or charity holdings first. If you find one, write the combined value and the fraction straight away.
Write the transfer as 'before − after' on one line. The related property effect then appears in the 'before' figure.
For quoted shares, write both measures side by side and circle the lower one.
Check the dates on a timeline. This tells you the QSR percentage, the taper percentage and whether fall in value relief is possible.
Calculate the tax on the estate first, then take off QSR. Do not adjust the nil rate band for QSR.

Common mistakes in Valuation Rules, Related Property and Quick Succession Relief

Valuing a gifted shareholding at its stand-alone price when a spouse holds shares in the same company.
Students value the asset given away and forget to check the family's other holdings.
Fix: Always look for related property. Value the combined holding, then apportion to the transferor.
Using the value received by the donee as the transfer of value.
This is how capital gains tax and everyday thinking work.
Fix: Apply the loss to donor rule. Write the estate before and after, and take the difference.
Choosing the quarter-up value for quoted shares without testing the bargains method, or using the average of the two quoted prices.
Students remember only one half of the rule.
Fix: Calculate both measures and use the lower. Quarter up is the lower price plus a quarter of the gap, not the mid-point.
Applying QSR against the value of the estate or using the wrong percentage band.
Students mix up QSR with taper relief or forget the scale, which is not in the tax tables.
Fix: QSR is a deduction from the tax. Use the scale by the gap between the earlier transfer and the death or later transfer: up to 1 year 100%, 1 to 2 years 80%, 2 to 3 years 60%, 3 to 4 years 40%, 4 to 5 years 20%.
Claiming QSR when the earlier receipt was an exempt transfer or a PET that stayed exempt.
Students see an inheritance or gift within five years and apply the relief automatically.
Fix: Check that the earlier transfer was chargeable and that tax was actually paid on it. An exempt spouse transfer gives no QSR.
Using fall in value relief to reduce the nil rate band used by the gift against later transfers.
Students think the lower value replaces the original value everywhere.
Fix: The lower value applies only when calculating the tax on that gift. The original value still counts for cumulation on later transfers.

Worked examples

Example 1

Tom owns 30% of the shares in Tom Ltd, an unquoted company. His wife Ann owns 25%. A 30% holding on its own is worth £120,000 and a 25% holding on its own is worth £90,000. The 55% holding is worth £330,000 in total. Tom gives all his shares to his son. Calculate the transfer of value and state how it is treated. Assume Tom has his annual exemption for the current year and the previous year available, and has made no other transfers.

Show the solution

Identify related property: Ann is Tom's spouse, so her shares are related property. Value the two holdings together at £330,000.
Tom's share of the combined value: 30 ÷ 55 × £330,000 = £180,000.
Estate before the gift: the shares are worth £180,000. Estate after the gift: Tom holds no shares, so the value is nil.
Loss to donor = £180,000 − nil = £180,000. If you had ignored related property you would have used £120,000, understating the transfer by £60,000.
Deduct the annual exemptions in date order: the current year's £3,000 first, then the previous year's £3,000. £180,000 − £6,000 = £174,000.
The gift is to an individual, so it is a PET. It is not chargeable now, so no tax is due at the time. It becomes chargeable only if Tom dies within seven years. In that case the £174,000 is covered by the nil rate band of £325,000, so no tax would be due on this gift, assuming no other transfers.

Answer: The transfer of value is £180,000 (not £120,000). After £6,000 of annual exemptions the PET is £174,000. It becomes chargeable only if Tom dies within seven years, and then it is covered by the £325,000 nil rate band.

Example 2

Mary died 2 years 6 months after her father. Under her father's will she received a legacy of £150,000. The father's estate paid IHT of £60,000 on that legacy, in addition to the £150,000 she received. At her death, Mary's estate was £1,000,000, including 10,000 quoted shares in Delta plc. On the date of death Delta plc shares were quoted at 410p to 418p, and recorded bargains ranged from 406p to 416p. Assume no residence nil rate band, no earlier transfers by Mary and the full nil rate band available. (a) Value the Delta shares. (b) Calculate the IHT payable on Mary's estate, after quick succession relief.

Show the solution

(a) Quarter up: 410p + ¼ × (418p − 410p) = 410p + 2p = 412p.
(a) Bargains: ½ × (406p + 416p) = 411p.
(a) The lower figure is 411p. Value = 10,000 × £4.11 = £41,100. This is part of the £1,000,000 estate.
(b) Tax before QSR: (£1,000,000 − £325,000) × 40% = £675,000 × 40% = £270,000.
(b) The legacy was a net amount, so the gross transfer is £150,000 + £60,000 tax = £210,000. The net increase to Mary's estate is £150,000.
(b) The gap is 2 years 6 months, which is more than 2 but not more than 3 years, so the percentage is 60%.
(b) QSR = 60% × £60,000 × (£150,000 ÷ £210,000) = £36,000 × 0.714286 = £25,714.
(b) Tax payable = £270,000 − £25,714 = £244,286.

Answer: (a) The Delta shares are worth £41,100. (b) Tax of £270,000 less QSR of £25,714 gives IHT payable of £244,286.

Exam tips

Look for family members or charities in the scenario before valuing any shares or land. A related property trap is common in Section A and Section B questions.
Show both quoted share measures in your working, even if the answer is obvious. The method earns marks and the lower figure is easy to pick.
Draw a short timeline with the dates of the gift, the earlier receipt and the death. This helps you find the taper, QSR and fall in value relief in one pass.
Remember that QSR and taper relief reduce the tax, while fall in value relief reduces the value. Say which one you are using and why.
Answer the requirement and add a short professional comment, such as the effect on cash flow or the planning point for the client. This helps your professional skills marks.

Practice questions from Inheritance tax: the liabilities arising on chargeable lifetime transfers and on death

Valuation Rules, Related Property and Quick Succession Relief: frequently asked questions

What is the loss to donor principle in inheritance tax?

It means the transfer of value is the fall in the donor's estate caused by the transfer. You value the estate before and after, then find the difference. The amount the recipient receives is irrelevant.

What counts as related property for IHT?

Property owned by the transferor's spouse or civil partner is related property. So is property held by a charity or similar exempt body, if it came from the transferor or their spouse by an exempt transfer and the body either still holds it at the date of transfer or held it within the previous five years. The gift can be much older than five years. You value the combined holding, then apportion the value to the transferor.

How do I value quoted shares for IHT in ATX?

Calculate two values. The first is the lower quoted price plus a quarter of the difference between the lower and higher prices. The second is the average of the highest and lowest recorded bargains. Use the lower of the two.

How is quick succession relief calculated?

Multiply the tax paid on the earlier chargeable transfer by the net increase to the estate divided by the gross transfer. Then apply the percentage for the time gap: up to 1 year 100%, 1 to 2 years 80%, 2 to 3 years 60%, 3 to 4 years 40%, 4 to 5 years 20%. Deduct the result from the tax on the later transfer or the death estate.

When does fall in value relief apply?

It applies when a lifetime gift becomes chargeable on death within seven years and the asset is worth less at death than when given. If the donee sold the asset earlier in an arm's length sale, the sale proceeds replace the value at death. The relief lowers the value of the gift used to calculate the tax on that gift. The original value is still used for cumulation on later transfers.
