Form 709
The annual federal gift and generation-skipping transfer tax return. A donor making gifts above the annual exclusion to any donee must file. The form is also the principal vehicle for allocating GST exemption and for "adequate disclosure" of gift values that starts the three-year statute of limitations.
What is reported
All gifts made during the calendar year except those wholly excluded by:
- §2503(b) annual exclusion (per donee).
- §2503(e) medical and tuition exclusion.
- §2522 charitable deduction (donee identification still required on form).
- §2523 marital deduction (with limited filings for QTIP elections and gift-splitting).
Who must report
Any U.S. citizen or resident donor who makes taxable gifts or who must report particular gift events (e.g., gift-splitting, GST allocations, partial-interest gifts of art under §170(o)).
Thresholds
For 2025 the annual exclusion is $19,000 per donee. Gifts to a single donee exceeding the exclusion require Form 709 reporting. Gifts to a U.S. citizen spouse benefit from unlimited marital deduction and (for outright gifts) generally do not require Form 709 unless the spouse is non-citizen (where a higher annual exclusion applies but reporting still required for above-exclusion gifts).
The form
Form 709 (United States Gift and Generation-Skipping Transfer Tax Return). Filed annually by April 15 of the year after the gift (with automatic six-month extension via Form 8892 or Form 4868 personal extension that also extends Form 709 timing).
Penalties
- Failure to file: 5% per month of unpaid tax, capped at 25% (rare given exclusion shelter).
- Accuracy penalty: 20% on substantial valuation understatement (claimed value 65% or less of correct value); 40% on gross misstatement (40% or less).
- Late payment interest under §6601.
Adequate-disclosure rules
Under §6501(c)(9) the three-year statute of limitations begins to run on a gift only if the gift is "adequately disclosed" on a Form 709. Treas. Reg. §301.6501(c)-1(f) sets adequate-disclosure standards — description, identity, value, method of valuation, qualified-appraiser statement for substantial property. Inadequate disclosure leaves the gift open to assessment indefinitely.
Relief procedures
Late-filed Forms 709 may be filed with reasonable-cause defense. Allocation of GST exemption may be made by late-filed Form 709 under §2632(d) with revaluation rules.
Recent guidance
The IRS continues to scrutinize valuation discount claims on family-entity-interest gifts and fractional-interest art gifts. Adequate-disclosure rigor is the principal defensive posture.
