IRS Form 709 Gift Tax Calculator

About this tool

The IRS Form 709 is filed to report taxable gifts and track your lifetime gift and estate tax exemption. Many gift-givers don't realize that gifts over the annual exclusion amount ($17,000 per recipient in 2023) must be reported, even if no tax is due immediately. This calculator removes the guesswork by computing your exact reporting obligation based on your gift amount and current exemption usage.

You need this tool if you're making substantial gifts to family members, trusts, or non-spouses, or if you've previously filed Form 709 and want to track cumulative exemption consumption. It's equally useful for estate planners advising clients on multi-year gifting strategies and for individuals near the federal exemption threshold who want to model different gift scenarios before committing funds.

Our AI-powered calculator goes beyond generic IRS tables. It accounts for your specific filing year, marital status, and prior gift history to produce a personalized exemption impact analysis. Free alternatives typically show only the basic annual exclusion threshold; we compute your remaining lifetime exemption and the precise Form 709 line-item entries you'll need, saving hours of spreadsheet work and reducing audit risk.

Example: A married individual with $500,000 in prior gifts files a Form 709 for a $100,000 gift in 2024. The calculator instantly shows the taxable portion ($83,000 after the annual exclusion), your remaining exemption balance ($11.61 million minus $583,000 = $11.027 million), and a step-by-step breakdown of the Form 709 entries you must complete—all with downloadable guidance for your tax professional.
