Inheritance tax and capital gains receipts
Inheritance tax (IHT) receipts reached a record £8.5 billion in 2025–26, an increase of £200 million on the previous year. This is largely attributed to the ongoing freeze of the nil-rate bands for inheritance tax at £325,000 and the residence threshold at £175,000, both fixed until 2031.
Rising property values have further expanded the number of estates affected. Additional changes to agricultural property and business reliefs, introduced from April 2026, are expected to broaden the scope of inheritance taxation. From April 2027, unused pension pots will be included in the IHT regime, a move anticipated to further boost receipts in future years.
Capital gains tax receipts have also shown a marked increase, reaching £22.2 billion up from £13.7 billion the previous year. This rise is linked to policy changes including a reduction in the annual exemption allowance from £12,300 to £3,000 and an increase in headline rates on most gains.
Rachael Griffin, a tax expert, noted that many investors took the opportunity to realise gains in response to the policy changes, which may have contributed to the especially high receipts observed.
