Inheritance Tax (IHT) is one of the most misunderstood taxes in the UK — partly because most estates never actually pay it, and partly because the rules around thresholds and reliefs are genuinely complex. Understanding the nil-rate band is the starting point for any conversation about IHT planning.
What the nil-rate band is
The nil-rate band is the amount your estate can be worth before Inheritance Tax becomes due. Anything below this threshold is generally taxed at 0%; anything above it is typically taxed at the standard IHT rate, subject to reliefs and exemptions. The nil-rate band has been frozen for a number of years, which means more estates have been drawn into IHT simply through rising property and asset values — even without any change in the underlying tax rules.
The residence nil-rate band
On top of the standard nil-rate band, there’s an additional allowance available when a main residence is passed to direct descendants (children, grandchildren, and so on). This residence nil-rate band can increase the total amount that can be passed on tax-free, but it comes with its own conditions and tapers away for larger estates — it isn’t automatically available to everyone.
Transferring unused allowance between spouses
Married couples and civil partners can transfer any unused nil-rate band (and residence nil-rate band) to their surviving partner. In practice, this often means a couple’s combined estate can pass on a significantly larger amount tax-free than either individual threshold suggests — but the transfer isn’t automatic and needs to be claimed correctly by the executors.
What counts towards your estate
Your estate for IHT purposes generally includes your property, savings, investments, and other assets, minus debts and funeral costs. Certain gifts made in the years before death can also be brought back into the estate calculation, depending on when they were made and to whom.
Common ways estates reduce their IHT exposure
- Making use of annual gift allowances during your lifetime
- Gifts that fall outside your estate after a qualifying period of survival
- Certain trust arrangements
- Life assurance written in trust, to help cover an eventual IHT liability without adding to the taxable estate
- Charitable giving, which can also reduce the rate charged on the rest of the estate
Each of these comes with its own rules, conditions and potential drawbacks, and what’s appropriate depends entirely on individual circumstances.
Why this needs individual planning, not a checklist
IHT planning touches on your family situation, your property, your investments, and how you want your estate distributed — it isn’t something to approach with generic rules of thumb. Thresholds, rates and reliefs also change from time to time, and figures that were accurate a year or two ago may no longer be.
The figures and thresholds referenced above are general and subject to change — always check current rates before making decisions, and note that we don’t provide tax advice; we work alongside your accountant or tax adviser where needed.
