UK Treasury Forecast: The IHT “Perfect Storm”

The UK Treasury’s Spring 2026 forecast presents a stark reality: Inheritance Tax (IHT) receipts are on track to nearly double, reaching £15 billion by 2030/31. As thresholds remain frozen, “fiscal drag” is pulling more modest estates into the 40% net.

Why the Surge?

  • Frozen Thresholds: The £325,000 Nil-Rate Band has been static since 2009, while house prices and equities climb.
  • New Caps: From April 2026, Agricultural Property Relief (APR) and Business Property Relief (BPR) will be capped at a combined £2.5 million for 100% relief.
  • Pensions in Scope: From April 2027, inherited pensions will be subject to IHT, removing a long-standing tax haven.

Strategic Planning is Essential

With the UK’s tax-to-GDP ratio hitting a post-war high of 38.5%, proactive wealth management is no longer optional.

  • Utilise Allowances: The £2.5 million APR/BPR allowance refreshes every seven years. Consider early gifting to “reset the clock.”
  • Spousal Transfers: Ensure your Will accounts for the new ability to transfer unused APR/BPR allowances between partners to protect up to £5 million.
  • Pension Reform: Reassess your “spend order.” It may now be more tax-efficient to draw down pension pots earlier rather than leaving them as a legacy.
  • Liquidity Planning: Consider life insurance held in a trust to provide the cash required to settle the tax bill without forcing a sale of family assets.

The Importance of Proactive Planning

The Office for Budget Responsibility (OBR) acknowledges that these forecasts are subject to “unpredictable behavioural responses.” This is a technical recognition that taxpayers have the right to take legitimate, proactive steps to mitigate the impact of new rules.

Strategic estate planning is no longer just about tax efficiency; it is about ensuring the continuity of family businesses and protecting the financial security of the next generation. By reviewing your Will and gifting strategies before the April 2026 deadline, you can ensure your legacy is distributed according to your wishes rather than being diminished by unforeseen liabilities.
