What the Autumn 2025 Budget means for probate and estate administration

Last year’s Autumn Statement marked a major shift in tax policy. It introduced changes to Inheritance Tax (IHT), pensions, business reliefs, and non-domiciled rules. These were described by Chancellor Rachel Reeves as necessary steps to “restore stability of public finances and rebuild public services.”

Twelve months on, the Autumn 2025 Budget builds on the foundations laid in 2024. While fewer headline tax changes were announced this year, many of last year’s reforms are now moving closer to implementation. This means individuals and estate practitioners may soon start to see real-world effects.

Below is a summary of the latest updates and what they could mean for estate planning, probate and estate administration.
