Transferring commercial real estate to the next generation during your lifetime — rather than leaving it through an estate — can be a powerful planning move. But the moment a property or an interest in it is given away, the IRS wants to know what it was worth. That value is reported on Form 709, the federal gift tax return, and it has to be supported by a credible appraisal. For gifts of commercial real estate and fractional interests, the valuation is the part of the transaction the IRS is most likely to test. Here is what gift tax valuations involve and why they demand rigor.
When a gift triggers Form 709
A gift is a transfer of property for less than full value, and the federal gift tax system tracks it. Two concepts frame the rules. The annual exclusion lets a donor give up to a set amount per recipient each year without a filing; the IRS sets and periodically adjusts that amount, and married couples can elect to combine their exclusions. Gifts beyond the annual exclusion to a single recipient generally bring Form 709 into play. A separate lifetime exemption — unified with the estate tax exemption — then determines whether any gift tax is actually owed, as taxable gifts draw against it. The current exclusion and exemption amounts, and whether a return is required, are questions for the donor’s CPA or attorney.
A gift of commercial real estate, or even a fractional interest in it, will almost always exceed the annual exclusion, which means Form 709 is in play and a value must be reported. Whether tax is ultimately owed is a question for the donor’s CPA or attorney; the reportable value is a question for the appraiser.
The standard: fair market value on the date of the gift
The value reported on Form 709 is the fair market value of the interest transferred as of the date of the gift — the price a willing buyer and willing seller would agree on, neither compelled and both reasonably informed. Unlike an estate valuation, the effective date here is current as of the transfer, not a date of death. For commercial property, reaching that value credibly means developing the appropriate approaches and documenting the supporting data, just as any defensible appraisal would.
Why gift valuations draw IRS scrutiny
Gift tax valuations of real estate — particularly fractional interests in property or entities — are among the areas the IRS examines most closely, because they sit at the heart of wealth-transfer planning. A poorly supported value invites adjustment, additional tax, and potential penalties. A qualified appraisal does the opposite: it substantiates the reported figure and documents the reasoning an examiner can follow.
There is also a long-term reason to value the gift correctly. A qualified appraisal supporting a properly filed return can help provide the donor a measure of finality against a later IRS challenge to the gift’s value. The mechanics of that protection are a matter for the donor’s tax advisor, but a credible appraisal is the foundation it rests on.
Fractional interests and valuation discounts
Lifetime giving frequently happens in pieces — a parent transfers an undivided fractional interest in a building, or interests in an entity that holds real estate, over several years. The value of a partial interest is not simply its pro-rata share of the whole. A minority interest may carry no control, and an interest in real estate or a closely held entity can be difficult to sell, so its fair market value can be less than a proportional slice of the entire property.
These dynamics underlie the valuation discounts often discussed in gift planning. The appraiser’s role is to value the actual interest transferred, on supportable grounds; the legal and tax treatment of any discount is for the donor’s attorney and CPA. This is a domain where appraiser and advisor coordination is essential, because the IRS examines these interests carefully and an unsupported discount is a frequent point of dispute.
What a Form 709 appraisal should establish
A gift tax appraisal of commercial real estate should clearly set out:
- The effective date — the date of the gift.
- The specific interest transferred — whole property, fractional interest, or entity interest.
- The definition of value — fair market value, consistent with gift tax requirements.
- The approaches and data — developed, documented, and reconciled with stated reasoning.
- A supporting workfile — retained so the value can be defended if examined.
Adherence to professional appraisal standards (USPAP) underpins the credibility of the whole report.
The bottom line
When commercial real estate or an interest in it is given away, Form 709 requires a reported value — and that value is exactly what the IRS is most inclined to challenge. A qualified, independent appraisal of the interest transferred, as of the date of the gift, is what substantiates the return, supports any valuation discount, and helps provide finality against later challenge. In lifetime wealth transfer, the appraisal is not a detail; it is the part that has to be right.

Frequently asked questions
When do I need an appraisal for a gift of real estate?
Whenever you transfer commercial real estate or an interest in it for less than full value and the gift exceeds the annual exclusion, Form 709 is generally required, and the reported value should be supported by a qualified appraisal. Your CPA or attorney can confirm the current thresholds and filing requirements.
Does filing Form 709 mean I owe gift tax?
Not necessarily. Taxable gifts draw against the lifetime exemption, so many reportable gifts generate no tax. Filing still documents the gift and its value; whether tax is owed is a determination for your CPA or attorney.
What are valuation discounts on gifts of real estate?
A fractional or minority interest in property or an entity may be worth less than its pro-rata share because of limited control and marketability. An appraiser values the actual interest on supportable grounds; the tax treatment of any discount is handled by your tax advisor, and the IRS examines these closely.
