Filing a gift tax return with zero tax owed sets a hard deadline after which the IRS can't argue about the property's value.

The Three-Year Lock

The Three-Year Lock

Under IRS rules, the clock starts after filing a gift tax return and runs for three years before the IRS can revalue the gift.

What Makes It Valid

The return must include a property description, parties involved, valuation method, and any discounts claimed to be legally binding.

Real Estate Protection

For lake houses and other high-value assets, a properly filed return locks the value against future IRS disputes during estate audits.

The Deadline

Form 709 is due April 15 of the year after the gift, with extensions possible until October 15.

Why It Matters Now

Filing today can prevent future IRS disputes over the lake house's value, even years after the gift.
