Giving Calculator · Tax Year 2026
See How Much Gifting Your Own DAF Could Reduce Your Taxes
Answer a few questions with round numbers. We estimate the deduction, the federal and state tax reduction, and the bracket you land in when you fund your own donor-advised fund this year. Then slide the gift up and down and watch the reduction move. It is an estimate to bring to your CPA, not tax advice.
Who will be making the gift?
Most business owners give personally: an S-corp, LLC, partnership, or sole proprietorship passes its income, and its gifts, through to your own return.
Nothing you type is stored or sent anywhere. The estimate runs in your browser.
Four Round Numbers Are Enough
You do not need your tax return open. Owners usually know these within a few percent, and a few percent does not change the picture.
Your income
A round estimate of this year’s adjusted gross income, per year or per quarter. Last year’s return is close enough.
What you already deduct
Mortgage interest, state and local taxes, medical. Zero is a fine answer; the estimate just stays conservative.
Your state
Your top state income tax rate, or skip it to see federal only.
The gift
Cash, or appreciated stock held over a year, and roughly how much you would move into your fund this year.

The calculator is education only and gives estimates based on the federal rules for tax year 2026 as we understand them; it is not tax, legal, or investment advice, and your results will differ. Nothing you enter is stored or sent anywhere. Kingdom Portfolios is not a CPA firm, a law firm, or an investment adviser, is not a DAF sponsor, and never receives, holds, or invests charitable dollars. Gifts to a donor-advised fund are irrevocable: the assets belong to the sponsoring charity, and you hold advisory privileges over grants. State tax treatment of charitable gifts varies. Confirm everything with your CPA and attorney before you give.
