A client recently came to my office with a wonderful plan. Her son and his wife were trying to buy their first apartment in Manhattan, and she wanted to give them $150,000 for the down payment. It was a generous, foundational gift for the next generation. After we discussed the best way to structure it, she asked a question I hear often: “This is a private family matter. How would the IRS ever even know?”
It’s a fair question. The transaction feels personal—a transfer between a parent and a child. Yet in the eyes of federal tax law, it is a significant movement of assets with clear reporting requirements. The assumption that gifts are private is a common and costly misunderstanding. The IRS does not have a window into your bank account, but it has built a system of reporting and verification that eventually brings large gifts to light.
The system isn’t designed to be punitive. It’s designed to ensure that wealth is transferred according to a consistent set of rules. Understanding those rules is the first step in prudent stewardship of your family’s legacy.
The Bright Line: When Reporting Becomes a Duty
The primary mechanism for tracking gifts is self-reporting, triggered by a clear dollar threshold known as the annual gift tax exclusion. For 2024, that amount is $18,000 per recipient.
This means you can give up to $18,000 to any number of individuals—your son, your daughter, your niece, a friend—in a single year without any tax implications or reporting duties. If you are married, you and your spouse can combine your exclusions and give up to $36,000 to each recipient. These gifts are truly private; the IRS does not need to know about them.
The duty to report arises the moment you give one person more than that annual exclusion. If you give a child $50,000 in one year, you have made a taxable gift of $32,000 ($50,000 minus the $18,000 exclusion). This does not mean you must write a check to the U.S. Treasury. For most people, it simply means you must file a federal gift tax return—Form 709.
This form documents the gift and applies the taxable portion against your lifetime gift and estate tax exemption. This is a large, unified credit that, for 2024, is over $13 million per person. Filing Form 709 simply tells the IRS, “I used a portion of my lifetime exemption this year.” No tax is due, but a paper trail is created. It is the first and most direct way the IRS learns of your gift.
The Long View: How Gifts and Estates Intersect
What happens if someone makes a large gift and fails to file Form 709? The IRS system has backstops. Unreported gifts are often revealed years or even decades later—usually after the giver has passed away.
When an individual dies, their executor must marshal all assets, pay debts, and distribute the remainder to the heirs. If the estate is large enough to require a federal or New York State estate tax filing, the executor must submit a return. That return demands a complete financial history, including an accounting of all taxable gifts made during the decedent’s lifetime.
The executor, acting as a fiduciary, has a legal duty to be thorough and truthful, signing the return under penalty of perjury. As part of this due diligence, they review bank records and financial documents. If they discover a $150,000 check to a child from a decade earlier with no corresponding Form 709, they have a problem. The gift must be reported retroactively. Any applicable penalties and interest must be paid. Suddenly, the “private” gift becomes a public matter in Surrogate’s Court.
This duty is codified in New York law. Under SCPA Article 22, an executor must account for all estate assets. Past, unreported gifts complicate this accounting, creating delays and potential liabilities for the estate and its beneficiaries.
Beyond Cash: Other Ways Gifts Are Found
The IRS does not rely on tax filings alone. Other transactions create public records that signal a gift.
Real Estate Transfers. A father gives his daughter the family home in Westchester. He transfers the deed for “$1 and other good and valuable consideration.” That deed is a public record filed with the county clerk. Tax authorities review these records. A property transfer far below market value is a clear indicator of a gift, valued at the fair market value minus the amount paid.
Bank Reporting. Banks do not report all transactions to the IRS, but they are required to report certain activities under federal law. Cash transactions over $10,000 are reported, as are suspicious patterns of fund movement. This is not a direct line to the gift tax division, but it creates a data point that can be uncovered during an audit.
Audits. An audit of your personal or business income taxes for an unrelated reason can uncover a large gift. An auditor who sees a $100,000 wire transfer from your account with no corresponding investment or purchase will ask where the money went. If the answer is “a gift to my nephew,” the next question will be, “May I see the Form 709 you filed?”
Intentional and prudent estate planning is not about hiding assets; it is about managing them transparently. The gift tax rules are a core part of that process. Acknowledging your reporting duties is not about paying taxes. For most, it is simply proper accounting to ensure a smooth transfer of your legacy.
If you have made significant gifts or plan to, the first step is understanding your obligations. We often begin with a confidential review of a family’s prior gifting history to identify any past filing requirements and establish a clear strategy for future generosity.
