Consulting a tax advisor can ensure your estate planning reflects the upcoming changes. Awareness of these changes ensures proper estate planning and compliance with HMRC requirements, avoiding potential IHT liabilities. Working with experienced accountants can help implement these changes efficiently.

Overview of IHT Changes

From April 2025, several key changes will affect Inheritance Tax planning. Using a AI accounting firm Wimbledon may assist in understanding these adjustments:
  • Adjustments to IHT nil-rate bands and residence nil-rate bands (RNRB)
  • Revisions to IHT reliefs including business and agricultural property relief
  • Updated rules for pensions included in IHT calculations

Nil-Rate Bands and RNRB

The IHT nil-rate band and residence nil-rate band thresholds will continue to be key considerations for estate planning. Executors must account for these thresholds when calculating tax liabilities.

Business and Agricultural Reliefs

Changes to IHT reliefs for business and agricultural assets will affect estates that include these qualifying assets. Executors need to understand how 50% or 100% reliefs apply post-April 2025.

Pension Inclusion in IHT

From April 2025, unused pension funds and death benefits will be considered part of the estate for IHT calculations. Pension administrators may be required to report and pay IHT on these funds.

Planning and Compliance Considerations

  • Review estate plans to account for updated IHT allowances and reliefs
  • Ensure accurate reporting to HMRC for all qualifying assets
  • Consider the impact on lifetime gifts and exemptions
  • Prepare documentation for executors and trustees to minimise potential IHT liabilities
