Autumn Budget 2024: Inheritance Tax Changes

Individuals, families, and estate planners seeking to understand the announced changes to Inheritance Tax (IHT) from the Autumn Budget 2024. Provides a clear overview of the IHT changes affecting business and agricultural reliefs, pensions, and nil-rate bands, helping estate planners and executors prepare for future liabilities. Awareness of these changes is essential for accurate estate planning and ensuring compliance with HMRC rules when these measures come into effect. A tax advisor can provide practical guidance on how these changes affect your estate.

IHT Reliefs

Changes were announced to IHT Business Relief and IHT Agricultural Property Relief. Currently, these reliefs can provide significant tax benefits for estates with qualifying business and agricultural assets. Under these reliefs, a benefit of either 50% or 100% relief is available from IHT with no cap. Consulting accountants ensures that reliefs are claimed correctly. From April 2026, qualifying estates with agricultural or business assets will only be able to claim 100% tax relief on the first £1 million of assets. Any value over £1 million will see tax relief restricted to 50%. Further consultation is expected next year with more details.

Inherited Pensions

Most undrawn private pensions are currently excluded from IHT. From 6 April 2027, the value of unused pension funds and death benefits payable will be included in IHT calculations. This means the pension pot will be added to other estate assets and potentially chargeable to IHT. Pension scheme administrators will also be responsible for reporting and paying any IHT due on unused pension funds and death benefits.

IHT Nil-Rate Bands

The IHT nil-rate bands have been frozen for a number of years and were set to remain at current levels until 5 April 2028. The Chancellor announced the freeze will now continue until 5 April 2030.
  • The nil-rate band will continue at £325,000
  • The residence nil-rate band will continue at £175,000
  • The residence nil-rate band taper will continue to start at £2 million
