Donor tools

What is your gift worth at tax time?

Estimate the tax benefit of a gift to a donor-advised fund using 2026 brackets and standard deductions.

How do you file?

It sets the standard deduction your gift has to clear before itemizing is worth anything. 2026 figures.

What the number means

  • It is the tax you do not pay

    Not the size of the gift. The estimate applies your marginal rate to the extra deduction your gift provides beyond what you would already deduct.

  • The standard deduction comes first

    Itemizing only pays once everything you would itemize adds up past it. Under that line, a gift changes nothing on your return.

  • There is a ceiling each year

    A gift can only be deducted against so much of your income in one year. What goes over carries forward for five more.

An estimate, not tax advice. It uses one marginal rate rather than working through the brackets, and it does not know anything else on your return. Talk to your own advisor before acting on it.

Give it before the year is out.
