UK families paid £8.5 billion in inheritance tax in 2025-26, according to HM Revenue & Customs' August 2026 receipts data. With frozen allowances and rising asset values, more owner-managed businesses are now being drawn into the tax net. If you've built a company, a family home, and savings for your children, addressing inheritance tax planning in the UK is a crucial decision for 2026, not something to put off.

You did not build that wealth so a large slice would leave the family at the worst possible moment. Early, human-centred advice can turn a feared bill into a clear plan for multi-generational wealth.

Why delay quietly raises the cost

Many families put these conversations off because they feel heavy or premature. This often means wills stay years out of date, company shares sit in one name, and adult children never hear the plan. Then, when illness or death arrives, the estate faces 40% tax above the tax-free bands. This can lead to slow administration and significant stress at home.

You can usually pass £325,000 free of inheritance tax. You may also pass an extra £175,000 when you leave your home to children or grandchildren, yet that extra amount tapers once an estate exceeds £2 million. A qualifying couple may pass up to £1 million if they meet the conditions, but only if ownership, wills, and family facts line up.

The 2026 trend that changes inheritance tax planning in the UK

Those tax-free amounts are set to remain frozen until at least 5 April 2030. Meanwhile, property and business values, particularly around London, continue their upward trajectory. HMRC reported the extra home-related relief at £2.44 billion for 2025-26, which shows both its value and how easy it is to miss the rules.

If you run an owner-managed business, hold investment property, keep assets overseas, or have trusts and pensions in the mix, valuation and cash problems can stack up fast. Protecting your family's wealth now depends on joining tax, succession planning in the UK, and probate in one conversation, ideally before a crisis sets the timetable.

For families shaping an estate plan in London , 2026 should be seen as a planning year, not a waiting year. A thorough review can uncover unused spouse transfers or business assets that need a closer look. It can also identify opportunities for lifetime gifts and highlight wills that no longer accurately reflect current ownership. Our comprehensive taxation and estate planning support is designed to help you build that full picture.

Your blueprint to keep more of what you built

Treat inheritance tax planning in the UK as a practical opportunity, not a paperwork chore. A clear sequence helps you capture reliefs, reduce rushed sales, and pass more to the people you love.

1. Map every asset, liability, and ownership structure, including the business and any overseas holdings.
2. Refresh wills, lasting powers of attorney, and shareholder agreements so they match today's family.
3. Test the extra home allowance, spouse transfers, and business assets against current values, not historic ones.
4. Build cash so an inheritance tax bill does not force a rushed sale of a home or company.
5. Hold a structured family meeting so the next generation understands the plan.
6. Agree who will handle probate, and favour CILEx regulated probate support when the estate is complex.

Families in Edgware often need that last step as much as the tax modelling. Our regulated probate services reduce avoidable delays and errors when an estate has several beneficiaries or mixed assets.

A second-generation couple in North London with a healthcare practice and two rental properties assumed they were ordinary taxpayers. A 2026 review showed the combined estate well above £1 million once the family home was included. By updating ownership, documenting succession, and planning gifts over time, they gave their children a clearer path and reduced the risk of a forced sale.

That is the growth opportunity. More of what you built stays in the family, with less conflict and more time to prepare the next generation.
