The 10% test
Let’s see how the 10% test operates by sharing a couple of examples. Before we delve into the calculations, it is important to clarify some key terms that underpin inheritance tax calculations involving charitable legacies:
Survivorship component – joint assets (joint tenancy) that pass automatically to the surviving co-owner.
Settled property component – assets for which the deceased was beneficially entitled to for example the life tenant of a qualifying interest in possession trust.
General component – the rest of the estate except the survivorship and settled property components as well as any property for which a gift with reservation (GWR) exists.
Available nil-rate band – Currently £325,000, increased by any transferable nil-rate band (TNRB) but reduced by previous chargeable lifetime transfers (CLTs) in the 7 years prior to death. This does not include any residential nil-rate band or transferable residential nil-rate band that might be available on the estate.
Donated amount - the amount gifted to charity in the will.
Baseline amount – the figure used to test whether the 10% threshold has been met. It is calculated in three steps:
Step 1 - Establish the chargeable transfer for each estate component.
Step 2 - Deduct the appropriate proportion of the available nil-rate band.
Step 3 - Add back the charitable legacy deducted at step 1 to arrive at the baseline amount.
