What the numbers mean
Inheritance Tax receipts have grown from £3.5 billion in 2006 to 2007 to £8.5 billion in 2025 to 2026, while the tax-free thresholds have been held at their 2020 to 2021 levels and are set to stay frozen to the end of the 2030-31 tax year (5 April 2031) (HMRC tax receipts bulletin, 2025 to 2026, subject to change; gov.uk, as at July 2026, subject to change). In our view, that combination helps explain why more estates are being drawn in and why funding the bill is becoming a more common question.
A second point stands out from the data. HMRC notes that, in estates below £1 million, the value is likely to sit mainly in residential property and cash (HMRC Inheritance Tax liabilities statistics, tax year 2022 to 2023). Property cannot be sold as quickly as a bank balance, so for many families the tax due can exceed the cash readily available. This is the gap the instalment option is designed to bridge, which may be why it can be relevant even for estates that are not especially large.
The trade-off is cost. Because later instalments generally carry interest at HMRC's rate, currently 7.75% (HMRC, as at July 2026, subject to change), spreading the tax can add materially to the total paid over a decade, except for Agricultural or Business Relief assets that may be interest-free from 6 April 2026. Whether the instalment route is worthwhile depends on the assets, the interest position and the family's plans, so it can be worth discussing with a qualified professional.

Frequently asked questions
Can all Inheritance Tax be paid by instalments?
No. The instalment option applies only to tax on certain assets that can take time to sell, such as houses, land, some shares, and the net value of a business, paid in 10 equal annual instalments (gov.uk, as at July 2026, subject to change). Tax on other assets, such as cash, is generally due within six months.
How many instalments can Inheritance Tax be paid in?
Qualifying Inheritance Tax can be paid in 10 equal annual instalments, with the first due at the end of the sixth month after the death and each further payment due on that date every year (gov.uk, as at July 2026, subject to change). An executor elects for the option on form IHT400 rather than it applying automatically.
Is interest charged on Inheritance Tax instalments?
Usually, yes. You generally will not pay interest on the first instalment unless it is late, but later instalments typically carry interest at HMRC's late-payment rate, which is 7.75% from 9 January 2026 (HMRC, as at July 2026, subject to change). Some Agricultural or Business Relief assets inherited from 6 April 2026 may be interest-free.
What happens to instalments if the asset is sold?
If the qualifying asset, such as a house or shares, is sold, the outstanding Inheritance Tax on it must be paid in full at that point rather than continuing over the remaining years (gov.uk, as at July 2026, subject to change). Many people therefore consider instalments where they intend to keep the asset.
How much Inheritance Tax does the UK collect?
UK Inheritance Tax receipts were £8.5 billion in the 2025 to 2026 financial year, up from £3.5 billion in 2006 to 2007 (HMRC, 2025 to 2026, as at July 2026, subject to change). Liabilities for 2022 to 2023 fell on 31,500 taxpaying estates (HMRC, 2022 to 2023, as at July 2026, subject to change).
Do the instalment rules differ in Scotland or Northern Ireland?
Inheritance Tax is a UK-wide tax, so the instalment rules apply in the same way across all four nations (gov.uk, as at July 2026, subject to change). The surrounding process differs: Scotland uses confirmation rather than a grant of probate, and Northern Ireland has its own but broadly similar procedures.
