8.1 Corporate Formation & Section 351 Transfer Requirements

Key Takeaways

  • IRC §351(a) provides mandatory nonrecognition of gain or loss when one or more persons transfer property to a corporation solely in exchange for stock and immediately after the exchange possess 80% control under IRC §368(c).

  • Control requires owning at least 80% of total combined voting power of all classes of voting stock AND at least 80% of the total number of shares of each class of nonvoting stock.

  • Services are specifically excluded from the definition of property under §351(d)(1); stock received for services generates immediate ordinary compensation income under §61 and §83 equal to fair market value.

  • A service contributor cannot count toward the 80% control group unless they also transfer more than nominal property (Rev. Proc. 77-37 safe harbor: property FMV must equal at least 10% of the value of stock already owned or received for services).

  • The shareholder receives a substituted basis in stock under §358 (transferred basis + gain recognized - boot received - liabilities assumed), while the corporation inherits a carryover basis in property under §362(a), with holding period tacking under §1223 for capital and §1231 assets.

Corporate Formation & Section 351 Transfer Requirements

When entrepreneurs organize a corporation or incorporate an existing business, the general realization rule of Internal Revenue Code (IRC) Section 1001 would ordinarily treat the exchange of appreciated assets for corporate stock as a fully taxable sale. However, Congress enacted IRC §351 to prevent the tax code from impeding business formation and structural reorganization. Section 351 reflects the underlying tax principle of continuity of investment: changing the legal form in which property is held—from individual ownership or partnership form to corporate equity—does not represent a cashing-in of the taxpayer's economic investment.

On the Special Enrollment Examination (SEE) Part 2, corporate formation under Section 351 is one of the most frequently tested areas of corporate taxation. Candidates must master the three statutory requirements for nonrecognition, understand how services alter control calculations under IRS revenue procedures, and compute shareholder stock basis (§358) and corporate asset basis (§362(a)) with surgical accuracy.


The Three Statutory Requirements of IRC §351(a)

Under IRC §351(a), no gain or loss is recognized if one or more persons transfer property to a corporation solely in exchange for stock of such corporation and immediately after the exchange such person or persons are in control of the corporation (as defined in IRC §368(c)).

Transferors (One or More Persons)
   │
   ├── Contributes: Qualifying "Property"
   │
   └── Receives: "Solely Corporate Stock"
   │
   ▼
Immediately After Exchange: Transferor Group Owns ≥ 80% Control (§368(c))
   │
   └── Result: Mandatory Nonrecognition (§351(a)) ──> Realized Gain/Loss Deferred

This nonrecognition treatment is mandatory, not elective. If all statutory criteria are satisfied, neither the transferor shareholders nor the transferee corporation can choose to recognize gain or loss.

Requirement 1: Transfer of "Property"

To qualify under Section 351, the transferor must transfer property. The Internal Revenue Code does not provide an exhaustive statutory definition of property for §351, but the courts and IRS rulings have established comprehensive parameters:

  • Qualifying Property: Cash (U.S. currency and foreign currency), real estate, tangible personal property (machinery, vehicles, inventory, office equipment), and intangible personal property (patents, copyrights, trademarks, secret formulas, trade secrets, goodwill, and customer lists). Cash-method accounts receivable also qualify as property.
  • Statutory Exclusions from Property (IRC §351(d)):
    1. Services (§351(d)(1)): Stock issued for past, present, or future services rendered to or for the benefit of the issuing corporation is not issued in return for property.
    2. Short-Term Indebtedness (§351(d)(2)): Indebtedness of the transferee corporation that is not evidenced by a "security" (e.g., an open accounts payable or unsecured short-term promissory note) does not qualify as property.
    3. Accrued Interest (§351(d)(3)): Corporate indebtedness that resulted in accrued interest on or after the beginning of the transferor's holding period is excluded.

Requirement 2: Solely in Exchange for Stock

The transferor must receive stock of the transferee corporation. The following equity instruments qualify as stock:

  • Voting common stock
  • Nonvoting common stock
  • Qualified preferred stock (voting or nonvoting)

Instruments That Do NOT Qualify as Stock:

  • Corporate Debt & Securities: Following the Revenue Reconciliation Act of 1989, corporate debt securities (bonds, debentures, long-term notes) no longer qualify as nonrecognition property under §351. Debt received by a transferor is treated as taxable boot.
  • Stock Rights, Options, and Warrants: Under Treas. Reg. §1.351-1(a)(1), stock rights and stock purchase warrants do not constitute stock.
  • Nonqualified Preferred Stock (NQPS): Under IRC §351(g), preferred stock that includes certain debt-like features (e.g., the holder has the right to require the issuer to redeem it, or the issuer is required to redeem it within 20 years) is treated as taxable boot rather than qualifying stock.

Requirement 3: "Control" Immediately After the Exchange (IRC §368(c))

The transferors—as an aggregated group—must possess control of the corporation immediately after the exchange. Control is defined strictly under IRC §368(c) and requires satisfying both prongs of a two-part test:

  1. Ownership of at least 80% of the total combined voting power of all classes of stock entitled to vote; AND
  2. Ownership of at least 80% of the total number of shares of each class of nonvoting stock (Rev. Rul. 59-259 requires 80% ownership of every separate class of nonvoting stock, not merely 80% in the aggregate).
IRC §368(c) Control Test:
├── Prong 1: ≥ 80% of Total Combined Voting Power (All Voting Classes)
└── Prong 2: ≥ 80% of Total Number of Shares of EVERY Nonvoting Class

Important

The 80% control test does not require each individual transferor to acquire 80%. Rather, it evaluates the transferor group collectively. All persons who transfer property as part of a single coordinated plan or transaction are pooled together to measure whether the group owns at least 80% immediately after the transfers.


Stock Received for Services: Taxation & Control Group Impact

When an individual receives corporate stock in exchange for labor, technical services, or management, the tax consequences depend on whether they contribute property in addition to services.

1. Pure Service Contributor

If a taxpayer receives stock solely in exchange for services rendered (e.g., legal counsel, architectural drawings, or promotional work):

  • Tax Treatment: Under IRC §61 and IRC §83, the service provider recognizes ordinary compensation income equal to the fair market value (FMV) of the stock received in the year it becomes substantially vested (or immediately if not subject to a substantial risk of forfeiture).
  • Control Group Exclusion: The pure service provider is not a property transferor. Consequently, zero percent (0%) of their stock counts toward the 80% control requirement under §368(c).
  • Impact on Other Transferors: If the property transferors do not independently own at least 80% of the stock after accounting for the shares issued to the service provider, the entire transaction fails Section 351, causing all property transferors to recognize gain on their appreciated contributions.

2. Dual Contributor (Property Plus Services) and Rev. Proc. 77-37

If an individual transfers both qualifying property and services in exchange for corporate stock, can their shares count toward the 80% control test?

  • General Rule: Under Treas. Reg. §1.351-1(a)(1)(ii), if a person transfers property of relatively small value compared to the value of the stock already owned or to be received for services, and the primary purpose of the transfer is to qualify the exchanges of other persons under §351, that person will not be treated as a transferor.
  • IRS Safe Harbor (Rev. Proc. 77-37 §3.07): For IRS advance ruling purposes, property transferred is not considered of relatively small value if the fair market value of the property transferred is equal to at least 10% of the fair market value of the stock and securities already owned (or to be received for services) by such person.
  • Mechanics of the Safe Harbor: When the 10% threshold is satisfied, all of that shareholder's stock (both the stock received for property and the stock received for services) counts toward satisfying the 80% control test for the transferor group. However, the shareholder must still recognize ordinary income on the value of the stock received for services under §83!
Contributor StatusOrdinary Income Recognized?Counts Toward 80% Control?
Property OnlyNo (§351 nonrecognition)Yes: 100% of shares count
Services OnlyYes: Ordinary income = FMV of stockNo: 0% of shares count
Property + Services (< 10% FMV)Yes: Ordinary income on service sharesNo: Deemed nominal under Treas. Reg. §1.351-1
Property + Services (≥ 10% FMV)Yes: Ordinary income on service sharesYes: 100% of shares count toward group control

Shareholder's Stock Basis Calculation (IRC §358)

Under IRC §358(a)(1), the shareholder receives a substituted basis in the stock received. This substituted basis preserves the deferred pre-contribution gain or loss so that it will be recognized upon a subsequent taxable sale of the stock.

The Section 358 Stock Basis Formula

Stock Basis=Adjusted Basis of Property Transferred+Cash Contributed+Gain Recognized by Transferor Shareholder−Fair Market Value of Boot Received−Cash Boot Received−Liabilities Assumed by Corporation (Section 358(d))\begin{aligned} \text{Stock Basis} = & \quad \text{Adjusted Basis of Property Transferred} \\ & + \text{Cash Contributed} \\ & + \text{Gain Recognized by Transferor Shareholder} \\ & - \text{Fair Market Value of Boot Received} \\ & - \text{Cash Boot Received} \\ & - \text{Liabilities Assumed by Corporation (Section 358(d))} \end{aligned}

If the shareholder receives multiple classes of stock (e.g., voting common and nonvoting preferred), the aggregate basis calculated above is allocated among the classes in proportion to their relative fair market values (Treas. Reg. §1.358-2).


Transferee Corporation's Property Basis (IRC §362(a))

Under IRC §362(a), the transferee corporation takes a carryover basis in the property received from the transferor shareholder.

The Section 362(a) Asset Basis Formula

Corporation’s Property Basis=Transferor Shareholder’s Adjusted Basis+Gain Recognized by Shareholder\text{Corporation's Property Basis} = \text{Transferor Shareholder's Adjusted Basis} + \text{Gain Recognized by Shareholder}

Notice the symmetry: if the shareholder recognizes no gain under §351(a), the corporation steps directly into the shareholder's shoes and takes an identical basis in the property.

Section 362(e)(2) Net Built-in Loss Limitation

To prevent the "double deduction" of losses (once by the corporation through depreciation or asset sale, and once by the shareholder upon selling the stock), IRC §362(e)(2) applies when the aggregate adjusted bases of properties transferred by a shareholder exceed their aggregate fair market value immediately after the transfer:

  • General Rule: The corporation's aggregate basis in the contributed assets is stepped down to their aggregate fair market value, with the step-down allocated proportionately to built-in loss assets.
  • Election to Reduce Stock Basis (§362(e)(2)(C)): The shareholder and corporation may make a joint election on their tax returns to preserve the corporation's higher carryover basis in the assets and instead reduce the shareholder's stock basis down to FMV.

Holding Period Tacking Rules (IRC §1223)

Holding periods determine whether gains or losses on future dispositions are classified as long-term (held > 1 year) or short-term:

1. Shareholder's Holding Period in Stock (IRC §1223(1))

  • Tacking Allowed: The holding period of the stock received includes (tacks) the shareholder's holding period in the contributed property only if the contributed property was a capital asset (IRC §1221) or Section 1231 asset (depreciable business property or real property held > 1 year).
  • No Tacking (Begins Day After Exchange): If the contributed property was an ordinary income asset (inventory, cash, or unrealized accounts receivable), or if the stock was received for services, tacking is disallowed. The holding period begins on the day after the exchange.
  • Split Holding Period: If a shareholder contributes a combination of capital/§1231 assets and ordinary assets, each individual share of stock has a split (fragmented) holding period allocated in proportion to the relative fair market values of the contributed properties.

2. Corporation's Holding Period in Property (IRC §1223(2))

  • The corporation's holding period in the received property always tacks the transferor's holding period, regardless of the nature of the property (capital, §1231, or ordinary income property).

Comprehensive Worked Formation Scenario

Facts: On March 1, 2025, Alex and Beatrice organize Apex Solutions Inc., a new domestic C corporation. Apex issues 100 shares of voting common stock:

  1. Alex transfers commercial equipment held for 3 years: adjusted tax basis of $45,000, fair market value of $80,000. In exchange, Alex receives 80 shares of Apex voting stock (FMV $80,000).
  2. Beatrice transfers $20,000 in cash. In exchange, Beatrice receives 20 shares of Apex voting stock (FMV $20,000).

Analysis:

  • Control Test (§368(c)): Alex and Beatrice are both property transferors (cash is property). Together, they own 100 out of 100 shares (100% control), which easily exceeds the 80% requirement. Section 351 applies.
  • Alex's Tax Consequences:
    • Realized Gain: $80,000 FMV - $45,000 basis = $35,000
    • Recognized Gain: $0 (§351(a) nonrecognition)
    • Alex's Stock Basis (§358): $45,000 (substituted basis of equipment)
    • Alex's Holding Period: Tacks the 3-year holding period of the equipment (§1231 property)
  • Beatrice's Tax Consequences:
    • Realized & Recognized Gain: $0
    • Beatrice's Stock Basis (§358): $20,000 (cash contributed)
    • Beatrice's Holding Period: Begins on March 2, 2025 (day after exchange)
  • Apex Corporation's Tax Consequences:
    • Apex recognizes $0 gain on issuing stock (§1032)
    • Apex's Inside Basis in Equipment (§362(a)): $45,000 (carryover basis)
    • Apex's Inside Basis in Cash: $20,000
    • Apex's Holding Period in Equipment: Tacks Alex's 3-year holding period

IRC Section 351 Qualification Decision Tree
Test Your Knowledge

Under IRC §351, which of the following transfers to a newly formed corporation qualifies as a tax-free exchange of property solely for corporate stock?

A

Arthur contributes commercial real estate in exchange for 85% of the corporation's only class of voting common stock.

B

Brenda performs legal and organizational incorporation services in exchange for 85% of the corporation's voting stock.

C

Charles contributes equipment for 70% of the voting stock, while an unrelated investor contributes cash for 30% of nonvoting preferred stock in an uncoordinated transaction three years later.

D

Diane contributes proprietary manufacturing patents in exchange solely for 10-year corporate debenture bonds.

Test Your Knowledge

Victor agrees to provide legal and organizational services worth $20,000 to form Newco Corporation. To ensure the transfer group meets the 80% control requirement under IRC §351, Victor also transfers cash of $3,000. In exchange, Victor receives 20% of Newco's sole class of stock worth $23,000. An unrelated investor, Wendy, transfers real estate (basis $50,000, FMV $92,000) for the remaining 80% of Newco stock. Under IRS guidelines (Rev. Proc. 77-37), how will Victor's transfer be treated for Section 351 control purposes?

A

Victor's stock cannot count toward the 80% control test because any contribution of services completely disqualifies a shareholder from being part of the transferor group.

B

Victor contributes $3,000 of property, exceeding 10% of the $20,000 stock received for services, so his stock may count in the transferor control group.

C

Victor recognizes no taxable income on the receipt of stock because he contributed cash alongside his services.

D

Victor's cash is disregarded as nominal, but Wendy qualifies for Section 351 on her own because she owns exactly 80% of Newco stock.
