Inheritance Tax by Jurisdiction

🇬🇧 United Kingdom — IHT

UK Inheritance Tax (IHT) is levied at 40% on estates above the nil-rate band (NRB) of £325,000. An additional Residence Nil-Rate Band (RNRB) of £175,000 applies when a main residence passes to direct descendants, giving a combined threshold of £500,000 per person (or £1,000,000 for a married couple if unused NRB is transferred). Transfers between spouses and civil partners are fully exempt.

🇺🇸 United States — Federal Estate Tax

The federal estate tax applies only to very large estates. The 2024 exemption is $13.61 million per individual ($27.22M for couples). The estate tax rate is 40% on amounts above the exemption. Most estates are exempt. Many states have their own separate estate or inheritance taxes with lower thresholds.

🇿🇦 South Africa — Estate Duty

South Africa levies Estate Duty at 20% on estates up to R30 million, and 25% on the balance above R30 million. There is a primary abatement of R3.5 million per deceased person (or R7 million for surviving spouses with unused abatement). Bequests to surviving spouses are fully exempt.

Frequently Asked Questions

No. Transfers between spouses and civil partners are fully exempt from UK IHT. Furthermore, any unused nil-rate band can be transferred to the surviving spouse's estate, potentially doubling the threshold to £650,000 (or £1,000,000 with RNRB).
South Africa does not have an "inheritance tax" as such — it has Estate Duty, which is levied on the deceased estate (not the beneficiary). Beneficiaries generally receive inheritances free of tax, though income earned after transfer is taxable.
Gifts made during your lifetime are generally Potentially Exempt Transfers (PETs). If you survive 7 years after making the gift, it falls outside your estate for IHT purposes. Gifts within 7 years of death are included in the estate, though taper relief reduces the IHT on gifts made 3–7 years before death.
