How does a charitable bequest reduce estate tax?
A bequest to a qualified charity is fully deductible from the gross estate when computing federal estate tax. Because there is no limit on the charitable deduction, every dollar given to charity reduces the taxable estate, saving up to 40 cents of federal estate tax per dollar for estates above the exemption.
Is the charitable estate tax deduction unlimited?
Yes. Unlike the income tax charitable deduction, which is capped at a percentage of income, the estate tax charitable deduction is unlimited. An estate can leave any amount to qualified charities and deduct all of it, potentially reducing the estate tax to zero.
Does a charitable bequest help if my estate is below the exemption?
For federal estate tax, no — an estate below the $13.61M (2024) exemption owes no estate tax, so the deduction saves nothing at the federal level. However, some states impose estate or inheritance tax at much lower thresholds, where a charitable bequest can still produce state-level savings.
How is this different from Canada?
The US grants an unlimited charitable deduction from the taxable estate, saving estate tax at 40%. Canada has no estate tax; instead a charitable bequest generates a donation tax credit on the deceased's final income tax return, offsetting the tax on the deemed disposition. The savings mechanisms are fundamentally different.
