Autumn Budget 2026: What does it mean for your Estate Planning?

Following today’s Autumn Budget 2026, much of the immediate attention will inevitably be on the measures affecting household finances. But for individuals and families thinking about how to protect and pass on their wealth, it is also a useful opportunity to take stock of their longer-term plans.

Estate planning rarely revolves around one tax change or one Budget announcement. A Will, pensions, savings, property, investments, business interests and lifetime gifts can all influence what ultimately passes to the next generation.

With further changes to the Inheritance Tax treatment of pensions already due to take effect from April 2027, and existing Inheritance Tax thresholds remaining frozen, there are good reasons to review how those different pieces fit together.

Cash ISA limit cut reversed

One of the announcements from the Budget is the reversal of plans to reduce the amount under-65s can pay into a Cash ISA each year. This means savers will continue to be able to put up to £20,000 a year into a Cash ISA, rather than facing the previously proposed £12,000 limit from April 2027.

While that may be welcome news for savers, an ISA’s tax advantages during a person’s lifetime should not be confused with Inheritance Tax planning. Money held in an ISA will generally still form part of an individual’s estate for Inheritance Tax purposes. For those with significant savings and investments, it is therefore worth considering ISA holdings as part of the wider estate rather than looking at them in isolation.

Pensions are becoming an important part of estate planning

One of the biggest changes arrives next year. From 6^th April 2027, most unused pension funds and death benefits are due to be included within an individual’s estate for Inheritance Tax purposes. Pensions passing to a spouse or civil partner will continue to benefit from the spouse exemption.

That could change the position for people who have historically planned to use other assets during retirement while preserving their pension to pass on to children or other beneficiaries.

Someone whose estate previously sat below the relevant IHT thresholds could also potentially find themselves in a different position once unused pension wealth is included.

It makes reviewing your Will in isolation increasingly difficult. Pension arrangements, beneficiary wishes, lifetime gifting and the provisions of your Will should all form part of the same conversation.

Frozen thresholds could bring more estates into focus

The standard Inheritance Tax nil-rate band remains at £325,000, while the residence nil-rate band is £175,000, with the thresholds frozen until 2031. For people who have not reviewed their estate planning for several years, it may therefore be worth looking again at the value and structure of their estate.

That doesn’t necessarily mean making immediate changes. It means understanding what you own, how those assets would pass on death and whether your existing arrangements still reflect what you want to achieve.

Don’t forget lifetime planning

Estate planning is not simply about what happens when somebody dies. Lifetime gifts, trusts and succession planning can all have a role, depending on an individual’s circumstances. However, gifting simply to reduce a potential Inheritance Tax bill can have unintended consequences, so decisions need to be considered alongside the individual’s own financial needs and longer-term intentions.

For business owners and farming families, that conversation can be particularly important given the changes to Agricultural Property Relief and Business Property Relief already in effect.

A good time to review your plans

The practical message from Budget 2026 is not that everyone needs to rewrite their Will or start giving assets away. It is that estate planning is increasingly interconnected.

Your Will, pensions, property, savings, investments, business interests and any lifetime gifts can all affect what ultimately passes to your beneficiaries and how efficiently it does so.

For anyone whose circumstances or wealth have changed since they last reviewed their Will and estate planning, now may be a sensible time to take stock.
