26 USC 351: Tax-Free Transfers to Controlled Corporations

A Section 351 tax-free transfer to a corporation lets you contribute property in exchange for stock without recognizing gain or loss, provided three conditions are met at the same time: what you transfer is “property” and not services, what you receive back is stock and not cash or debt, and the people contributing property (you alone, or together with others in the same transaction) own at least 80% of the corporation immediately after the exchange.¹

The deferral is not forgiveness. Your gain stays embedded in the basis of the stock you receive and in the corporation’s basis in the property, ready to be recognized when either is later sold. Because the statute has several trapdoors, the specifics of what you transfer, what you get back, and who else is involved matter more than the general rule.

What Counts as Property

“Property” is broad. Real estate, equipment, inventory, cash, patents, trademarks, copyrights, and contractual rights all qualify. You can contribute liquid assets or hard-to-value intangibles and still get deferral, so long as the other requirements hold.

The big exclusion is services. Stock issued for services, whether already performed or promised for the future, is not issued for property under the statute, and the recipient reports its fair market value as ordinary compensation income.² The Fifth Circuit confirmed this in United States v. Frazell, holding that stock received for professional services was fully taxable regardless of the transferor’s intent.³

Two other items also fall outside property: unsecured debt owed by the corporation receiving the transfer, and interest on that debt that accrued during the transferor’s holding period. Stock issued for either gets the same treatment as stock issued for services.²

Personal goodwill is the gray area that catches business owners incorporating a sole proprietorship or professional practice. Goodwill tied to your reputation, relationships, or skills can qualify as property, but only if it represents a genuinely transferable asset separate from your ongoing services. Courts look at whether the goodwill has independent value the corporation can use without your continued involvement. If it’s really a promise that you’ll keep working, it collapses back into services and becomes taxable.

The 80% Control Test

Control means owning at least 80% of the total combined voting power of all voting stock and at least 80% of the total shares of every class of nonvoting stock.⁴ Both prongs must be satisfied at the same time, and the test is applied “immediately after” the exchange.

Multiple people transferring property in the same transaction pool their ownership to reach 80%. Only those who actually contribute property and receive stock count. A person who receives stock solely for services is not a transferor of property, and their shares are excluded from the numerator when you measure whether the property transferors hit the threshold.¹

Accommodation Transferors

A common workaround has an existing shareholder contribute a small amount of property alongside a new shareholder so the group crosses 80%. Treasury regulations block this when the property contributed is “relatively small in value” compared to the stock the existing shareholder already owns and the primary purpose is to help other transferors qualify. In that case, the existing shareholder’s contribution is disregarded, and the remaining transferors must satisfy the 80% threshold on their own.⁵

Prearranged Stock Sales

“Immediately after” is more than a snapshot. If a transferor has a binding agreement to sell their stock to a third party before or at the time of the exchange, the IRS treats them as never having held it for control purposes. In Intermountain Lumber Co. v. Commissioner, an incorporator’s binding obligation to sell shares as payments came in meant he had effectively relinquished ownership; the court held the control requirement was not met, and the entire transaction lost its tax-deferred status.⁶

The IRS has said that a binding commitment to make a nontaxable disposition of the stock, such as a tax-free reorganization, does not necessarily break control, because that kind of disposition is consistent with Congress’s intent to facilitate rearrangements of property interests. A binding commitment to make a taxable sale, on the other hand, destroys it.⁷

What You Can Receive Without Triggering Tax

Full nonrecognition requires that you receive only stock. Voting and nonvoting shares both work, as do common and most preferred shares. Debt instruments, stock options, and warrants do not count as stock for Section 351.

Anything else you receive is “boot.” Boot includes cash, non-stock property, and certain debt-like preferred stock. When you receive boot alongside stock, you recognize gain up to the lesser of your realized gain or the boot’s value. Realized gain of $50,000 with $20,000 of cash boot means $20,000 of recognized gain. Realized gain of $10,000 with $20,000 of boot means only $10,000 recognized.⁸

You can never recognize a loss in a Section 351 exchange, even when you receive boot. If you transfer property worth less than your basis and receive boot, the loss is trapped in your stock basis and cannot be deducted at the time of the exchange.⁹

Nonqualified Preferred Stock Counts as Boot

Preferred stock that behaves too much like debt gets reclassified as boot under Section 351(g). Four features make preferred stock “nonqualified”:

The holder can require the corporation to redeem the stock.
The corporation is required to redeem the stock on a schedule.
The corporation has a right to redeem, and as of the issue date it is more likely than not to do so.
The dividend rate varies with interest rates, commodity prices, or similar benchmarks.

The first three apply only if the redemption right or obligation can be exercised within 20 years of the issue date and isn’t subject to a remote contingency. Exceptions exist for redemption triggered only by the holder’s death, disability, or mental incompetency.¹⁰

Receive nonqualified preferred stock alongside regular stock and the preferred is boot, generating gain (never loss) up to its fair market value. Receive nothing but nonqualified preferred stock and Section 351 doesn’t apply at all; the whole exchange is taxable.

Disproportionate Stock Issuance

When several people contribute property but receive stock in proportions that don’t match what each contributed, the IRS looks past form to substance. The excess stock can be recharacterized as a taxable gift, compensation for services, or payment of an obligation, depending on the parties’ relationship.⁵ Section 482 also lets the IRS reallocate income among related businesses when the split doesn’t reflect economic reality.¹¹

When the Corporation Takes On Your Debt

Contributing property with debt attached does not automatically disqualify the exchange. Contribute mortgaged real estate and the corporation’s assumption of the mortgage is generally not boot. The problem starts when the total liabilities assumed exceed the total adjusted basis of the property you transferred. The excess is treated as gain from a sale or exchange.¹²

One exception matters in practice. Liabilities whose payment would produce a deduction, such as trade payables or accrued expenses, are excluded from the excess-liability calculation. Transfer a building with a $500,000 mortgage and $100,000 in accrued environmental cleanup costs that would be deductible when paid, and only the mortgage counts against your basis for measuring the excess.¹³ The exclusion doesn’t apply if the liability already created or increased the property’s basis.

Even when liabilities don’t exceed basis, the IRS can treat the entire assumed liability as boot if the principal purpose was to avoid federal income tax or if the assumption had no legitimate business purpose. In that case the full amount of the liability, not just any excess over basis, is treated as cash received.¹⁴ This is a potent anti-abuse rule and it applies before Section 357(c) even runs.

Your Basis After the Exchange

Deferral shifts gain into basis. The numbers you compute at the exchange determine what you owe later.

Your Basis in the Stock

Your basis in the stock you receive equals your basis in the property you transferred, adjusted as follows:

Decreased by cash received, the fair market value of any non-stock property received, and any loss recognized.
Increased by any gain recognized on the exchange and any amount treated as a dividend.

Liabilities the corporation assumes are treated as cash received for this calculation, which reduces stock basis.¹⁵ Transfer property with a $100,000 basis subject to a $30,000 mortgage and your stock starts at $100,000 and drops to $70,000.

The Corporation’s Basis in the Property

The corporation takes a “transferred basis,” inheriting whatever basis you had. If you recognized gain on the exchange because of boot, the corporation’s basis increases by that recognized gain. When gain arises solely from assumed liabilities under Section 357(c), the basis increase cannot push the corporation’s basis above the property’s fair market value.¹⁶

Built-in Loss Property

When the aggregate basis of the property a transferor contributes exceeds the aggregate fair market value, Section 362(e)(2) caps the corporation’s basis in the property at fair market value, preventing the same loss from being duplicated at the shareholder and corporate levels. The reduction is spread across the contributed assets in proportion to each asset’s built-in loss.¹⁷

The transferor and the corporation can jointly elect to shift the limitation. Make the election and the corporation keeps full transferred basis in the property, but the transferor’s basis in the stock drops to fair market value instead. That election can help when the corporation will use the property and the shareholder plans to hold the stock long-term.

Holding Period

When you receive stock in exchange for property that was a capital asset or Section 1231 property, your holding period in the property “tacks” onto the stock. Hold the contributed property for three years before the exchange and your stock is treated as held for three years from day one, which matters for long-term capital gains treatment on a later sale.¹⁸ Tacking requires the exchanged property to have had a substituted basis (which Section 351 provides) and to have been a capital asset or Section 1231 property. Contribute inventory or other non-capital property and the holding period on the stock starts fresh on the exchange date.

The Investment Company Trap

Section 351 does not apply to a transfer that effectively lets you diversify a concentrated portfolio tax-free. A transfer is treated as a transfer to an “investment company” when two conditions are both met: the transfer results in diversification of the transferors’ interests, and the corporation is a regulated investment company, a real estate investment trust, or a corporation holding more than 80% of its assets (excluding cash and nonconvertible debt) in readily marketable stocks, securities, or interests in those entities.⁵

Diversification typically happens when two or more people contribute non-identical assets. A single transferor contributing one type of stock to a newly formed holding company generally does not create diversification. If the transfer is part of a broader plan to achieve diversification through a later step, the IRS will look through the steps and treat the original transfer as producing diversification. “Readily marketable” means publicly traded on an exchange or regularly quoted over the counter, and the definition pulls in convertible debentures, convertible preferred stock, and warrants when the underlying stock is readily marketable.

Reporting the Exchange

A qualifying Section 351 exchange doesn’t generate tax, but it does generate paperwork. Treasury regulations require disclosure statements from both sides.

Each “significant transferor” attaches a statement to the tax return for the year of the exchange. It must give the corporation’s name and employer identification number, the dates of the transfers, and the fair market value and basis of the property transferred, broken into categories: loss importation property, loss duplication property, property on which gain or loss was recognized, and all other property. Any related private letter rulings must be referenced.¹⁹

The receiving corporation files a parallel statement with its own return, identifying every significant transferor and reporting the fair market value and basis of the property received using the same categories. If the information is already in the transferors’ statements attached to the same return, the corporation can skip its own filing, which mostly matters for single-member formations.¹⁹

Missing these statements doesn’t automatically disqualify Section 351 treatment, but it can extend the statute of limitations and draw scrutiny. Getting the disclosures right at the front end costs far less than defending an incomplete filing later.
