Adequate Disclosure and the Gift Tax Statute of Limitations

Gift tax returns are often treated as a formality: list the gift, list the value, sign, file. For cash gifts, that works fine. For anything harder to value, it can leave the gift exposed for the rest of the donor's life and beyond.

The difference between a return that closes the statute of limitations and one that does not comes down to a regulation most families have never heard of: Treas. Reg. 301.6501(c)-1(f), the adequate disclosure rule.

Why the statute matters so much for gifts

Generally, the IRS has three years after a return is filed to assess more tax under IRC 6501(a). For gifts, IRC 6501(c)(9) adds a significant exception: if a gift required to be shown on a return is not shown, the tax on it may be assessed at any time. The statute then adds that the exception does not apply to any item disclosed on the return, or on an attached statement, in a manner adequate to apprise the IRS of the nature of the item.

Once the three years run on an adequately disclosed gift, IRC 2504(c) generally prevents the IRS from revaluing it when computing later gift tax. IRC 2001(f) applies the same principle to adjusted taxable gifts in the estate tax computation. So an adequately disclosed gift of an LLC interest, valued with a 30 percent discount in 2022, is locked in once the period expires, even if the IRS would have argued for a smaller discount.

A gift that was reported without adequate disclosure gets no such protection. It can be revalued in 2040 when the donor's estate tax return is examined.

What the regulation requires

Treas. Reg. 301.6501(c)-1(f)(2) provides that a transfer reported as a gift is adequately disclosed if the return, or a statement attached to it, provides:

1. A description of the transferred property and any consideration received by the transferor.
2. The identity of, and relationship between, the transferor and each transferee.
3. For transfers in trust, the trust's tax identification number and a brief description of the trust terms, or a copy of the trust instrument.
4. A detailed description of the method used to determine fair market value, including financial data used, any restrictions on the property considered in valuing it, and a description of any discounts claimed, such as discounts for minority interests, fractional interests or lack of marketability.
5. A statement describing any position taken that is contrary to proposed, temporary or final Treasury regulations or revenue rulings published at the time of the transfer.

Item 4 carries the most weight and causes the most failures. For publicly traded stock, it is easy: the regulation says reciting the exchange, the CUSIP number, and the mean of the high and low prices on the valuation date is enough.

For interests in entities that are not actively traded, the regulation asks for more. The return must describe any discount claimed in valuing the interest or the entity's assets. If the value is properly based on the entity's net asset value, the return must state the fair market value of 100 percent of the entity without discounts, the pro rata portion transferred, and the value of the transferred interest as reported. If an entity owns interests in other non-traded entities, the same information may be needed for each one.

The appraisal alternative

Treas. Reg. 301.6501(c)-1(f)(3) provides a way to satisfy item 4 with an appraisal instead of a narrative. The appraiser must:

• Hold themselves out to the public as an appraiser or perform appraisals regularly.
• Be qualified to appraise the type of property, as shown by background, experience, education and professional memberships described in the appraisal.
• Not be the donor, the donee, a family member of either, or anyone employed by them.

The appraisal itself must contain the date of transfer, the appraisal date and purpose; a description of the property; the appraisal process; assumptions and limiting conditions; the information considered, including financial data detailed enough for someone else to replicate the result; the procedures and reasoning; the valuation method and rationale; and the specific basis for the valuation, such as comparable sales.

That is a demanding list. A two-page broker opinion of value for a Sarasota rental property does not meet it. The guide to valuation disputes explains why appraisal quality decides most of these fights. A full appraisal from a certified appraiser who knows the requirement usually does.

Non-gift transactions

Families often structure transfers that they believe are not gifts at all: a sale of real estate to a child at appraised value, a sale of LLC interests to a family trust for a note, or a loan at the applicable federal rate. If the IRS later decides the price was too low, part of the transfer was a gift, and it was never reported.

Treas. Reg. 301.6501(c)-1(f)(4) addresses this. Completed transfers to family members in the ordinary course of operating a business, like salary to a family employee, are deemed adequately disclosed if properly reported for income tax. For other completed transfers, the regulation allows the transferor to disclose the transaction on a Form 709 even though it is not reported as a gift, with the information the regulation requires plus an explanation of why the transfer is not a gift.

Disclosing a non-gift transaction starts the clock. It also helps the family later, because it documents the parties' position while the facts are fresh. For the basics of which gifts require a return in the first place, see when a Form 709 is required.

If the three years pass without challenge, the IRS cannot later reopen it as a gift. That is cheap protection for transactions with real dollars at stake.

Common disclosure failures

• Listing "LLC interest" with a value and no appraisal, no entity value, and no explanation of discounts.
• Reporting a gift to a trust without the trust's EIN or terms.
• Attaching an appraisal by a family member or the donor's CPA who does not regularly perform appraisals.
• Reporting a gift of real estate at the county assessed value.
• Omitting a part-sale, part-gift transaction entirely because the family considered it a sale.
• Failing to describe a position contrary to a published revenue ruling.

Any one of these can leave the gift open indefinitely.

Fixing an inadequate return

If you have filed 709s that do not meet the standard, the usual approach is to file a supplemental return for that year supplying the missing information, including a qualified appraisal as of the original gift date. Do not expect the clock to reach back to the original filing. The IRS cannot be charged with information it never received, so the period should be measured from the filing that actually made the disclosure adequate.

The same is true for returns that were never filed. A late return with adequate disclosure starts the clock. See unfiled and late gift tax returns.

Why executors should care

When a donor dies, the estate tax computation adds back adjusted taxable gifts. An estate tax examiner reviewing a Form 706 will look at every gift the decedent made. Gifts that were adequately disclosed with an expired statute are generally fixed. Gifts that were not are fair game. See what happens in an estate tax audit.

Executors should gather all prior 709s early and ask whether each one meets the adequate disclosure standard. The answer shapes how much risk sits in the estate tax return.
