Inheritance Tax Act 1984 section 226

Payment: general rules

Section 226 sets out the general rules governing when inheritance tax becomes due for payment, including the standard due dates for chargeable transfers, the obligations of personal representatives, and the timing of tax arising from failed potentially exempt transfers and other specific chargeable events.

• Inheritance tax on a chargeable transfer is generally due six months after the end of the month in which the transfer is made, but for transfers made between 6 April and 30 September (other than on death), tax is due by the end of the following April.
• Personal representatives must pay all the tax for which they are liable when they deliver their account, and may also pay tax for which others are liable if those persons request it.
• Where a potentially exempt transfer becomes chargeable because the transferor dies within seven years, or where additional tax arises on a settlement charge because the settlor dies within seven years, the tax is due six months after the end of the month of death.
• Tax arising from specific chargeable events — such as breach of conditional exemption conditions, ten-yearly charges on designated property, or disposal of woodlands — is due six months after the end of the month in which the event occurs.
