The UK inheritance tax (IHT) nil-rate band has been frozen at £325,000 since 2009, catching an increasing number of estates in its net. High earners face particular exposure, having accumulated significant wealth throughout their careers. With IHT charged at 40%, strategic planning becomes essential to protect your estate.
Understanding IHT and the Nil-Rate Band
The IHT nil-rate band represents the amount of an estate exempt from tax. For 2025/26, this remains at £325,000. Everything above this threshold attracts IHT at 40%. An estate valued at £500,000, for example, would incur an IHT bill of £70,000 (40% of the £175,000 excess). Understanding how IHT applies to your circumstances allows you to deploy effective planning strategies.
Gifts and IHT Planning
Lifetime gifts offer one of the most straightforward IHT planning tools. Gifts made more than seven years before your death fall outside your estate entirely. A £100,000 gift to your child, followed by seven years of survival, removes that sum from IHT calculations. Die within seven years, however, and the gift becomes part of your taxable estate. Maintaining detailed records of all gifts is vital for HMRC reporting.
Business Relief and IHT Planning
Business Relief provides substantial IHT advantages for business owners. Qualifying business assets can be reduced in value for IHT purposes, sometimes achieving 100% relief. A £1 million business with full relief exempts the entire value from tax. The qualifying criteria are stringent, however, making professional guidance essential to claim relief correctly.
Trusts and IHT Planning
Trusts allow you to remove assets from your taxable estate while maintaining a degree of control. Placing £200,000 into a trust excludes it from IHT calculations entirely. Trust structures vary significantly, and each carries different tax implications. Setting up and managing trusts correctly requires specialist advice to maximise their IHT benefits.
Timeframe for IHT Planning
Effective IHT planning demands a long-term perspective. Begin your strategy 5–10 years before retirement to fully leverage available tools. A 50-year-old planning to retire at 60 should start today, ensuring gifts have time to fall outside the seven-year window and allowing Business Relief and trust structures to mature properly.
Reviewing and Updating IHT Plans
Your circumstances and tax rules change over time. Regular plan reviews ensure your strategy remains aligned with both. A growing business may justify revised Business Relief claims. Market movements shift asset values. Relationship changes affect beneficiary arrangements. Annual or biennial reviews keep your structure tax-efficient and compliant.
