Over 40% of candidates fail the REG section of the CPA exam in any given window. A surprising number of those points are lost not on obscure partnership rules, but on a topic candidates think they know cold: the formation of a C Corporation under IRC §351. They memorize the basis formula but misapply it to liabilities, failing the very first step of the analysis.
Corporate formation on the REG exam tests your application of IRC §351 for nonrecognition treatment. You must calculate shareholder basis (property basis + gain recognized - boot received - liabilities assumed) and corporate basis (shareholder's basis + gain recognized), recognizing gain only when boot is received or liabilities exceed basis.
Key facts
- Governing Rule: Internal Revenue Code (IRC) §351 for nonrecognition transactions.
- Control Test: Transferors of property must own ≥80% of voting power and ≥80% of all other stock classes.
- Key Liability Rule: Per IRC §357(c), gain is recognized when liabilities assumed exceed the property's adjusted basis.
- Exam Section: Regulation (REG)
- Question Format: Multiple-Choice Questions (MCQs) and Task-Based Simulations (TBS).
- Official Body: American Institute of Certified Public Accountants (AICPA).
Why Does Corporate Formation Matter on the REG Exam?
Corporate formation and capitalization covers the tax rules for creating a C Corporation. The entire topic is built around IRC §351, which allows shareholders to transfer property for stock without recognizing an immediate gain. The AICPA reports that Taxation of Entities is a major part of the REG blueprint, and §351 is the gateway to that topic.
The exam tests your judgment, not just your memory. You will face scenarios with multiple shareholders, some contributing property, some cash, and some services. You'll have to untangle liabilities and cash payments ("boot") to arrive at the correct gain and basis for each party.

The single most common error is miscalculating the shareholder's initial basis in their stock. Candidates forget that liabilities assumed by the corporation reduce their basis. This one mistake creates a domino effect, leading to incorrect answers for gain recognized, corporate basis, and future stock sales. Our goal is to give you a systematic process to avoid that trap.
The IRC §351 Decision Tree: A Step-by-Step Guide
Approach every formation problem with a precise, repeatable process. Don't guess. Follow these steps.
Step 1: Does the exchange qualify under §351?
Before calculating anything, confirm the transaction qualifies for nonrecognition treatment. If it fails, it's a simple taxable sale at fair market value. There are two conditions.
- Property for Stock: Shareholders must transfer property. Services do not count.
- 80% Control: The group of shareholders transferring property must collectively own at least 80% of the total combined voting power and at least 80% of the total number of shares of all other classes of stock immediately after the exchange.
This is a two-part test, and the exam can trick you on either part.
| Contribution Type | Counts for §351 Control? | Shareholder's Tax Treatment |
|---|---|---|
| Property (Cash, Equipment, Land) | Yes | No gain or loss recognized (unless boot received). |
| Services (Legal, Accounting) | No | Taxable as ordinary income on the FMV of stock received. |
Step 2: How do you calculate the shareholder's gain and basis?
Once you confirm §351 applies, calculate the consequences for the shareholder. The realized gain is the economic profit (FMV of what was received - Basis of what was given), but the recognized gain is often zero.
Gain is only recognized to the extent of the lesser of the realized gain or the boot received.
"Boot" is any non-stock property received by the shareholder, like cash or debt instruments. The assumption of a liability is a special case. Generally, it's not boot, but it does reduce the shareholder's stock basis. However, gain is triggered in two situations:
- §357(b): The principal purpose of the liability assumption was to avoid federal income tax. The entire liability is treated as boot.
- §357(c): The sum of liabilities assumed exceeds the adjusted basis of the property transferred. The excess amount is a recognized gain. This gain is recognized regardless of the realized gain on the transaction.
With that, you can calculate the shareholder's basis in their new stock.
> 🧮 Formula: Shareholder's Stock Basis > > Adjusted Basis of Property Contributed > + Gain Recognized > - Boot Received (Cash + FMV of non-stock property) > - Liabilities Assumed by the Corporation > = Shareholder's Basis in Stock
The VoraPrep adaptive learning engine has over 9,500 questions to drill this specific calculation until it's second nature.
Step 3: How do you calculate the corporation's basis?
Next, determine the corporation's basis in the property it received. This is often called a "carryover" or "substituted" basis because it's linked to the shareholder's original basis.
> 🧮 Formula: Corporation's Property Basis > > Shareholder's Adjusted Basis in the Property > + Gain Recognized by the Shareholder > = Corporation's Basis in the Property
Notice the symmetry: the gain a shareholder recognizes increases both their stock basis and the corporation's asset basis.
| Basis Calculation | Shareholder's Stock Basis | Corporation's Property Basis |
|---|---|---|
| Starts with... | Shareholder's AB of property given | Shareholder's AB of property given |
| Increased by... | Gain recognized by shareholder | Gain recognized by shareholder |
| Decreased by... | Boot received & Liabilities assumed | Not applicable |
| Result is... | Basis in new stock received | Basis in new asset received |
Step 4: What about holding periods?
The holding period is a frequent MCQ topic.
- Shareholder: The holding period of the property contributed tacks on to the holding period of the stock received, provided the property was a capital asset or §1231 asset. For any boot received, the holding period begins on the date of the exchange.
- Corporation: The corporation's holding period for the property it receives also includes the period the shareholder held it.
How Are Organizational Costs Treated Under IRC §248?
Forming a corporation involves costs for legal services, accounting fees, and state incorporation fees. Under IRC §248, a corporation can elect to:
- Immediately deduct up to $5,000 of these costs.
- This $5,000 first-year deduction is reduced dollar-for-dollar by the amount total costs exceed $50,000. (So, if costs are $52,000, the immediate deduction is only $3,000).
- Any remaining costs are amortized straight-line over 180 months, beginning with the month the corporation starts its business.
Memorize the $5,000, $50,000, and 180-month figures. They are perfect MCQ fodder.
Worked Example: Spotting the §351 Failure
Let's apply this decision tree to a multi-layered problem designed to trap you.
> 💡 Worked example: > > Carlos and Diana form a new C Corporation, CD Inc. > > * Carlos transfers equipment with an adjusted basis of $60,000 and a fair market value (FMV) of $100,000. The equipment is subject to a mortgage of $10,000, which CD Inc. assumes. In exchange, Carlos receives 70 shares of CD Inc. stock (valued at $70,000) and $5,000 cash. > * Diana provides legal services valued at $25,000 in exchange for 25 shares of CD Inc. stock. > > What is Carlos's recognized gain and his basis in the CD Inc. stock? What is CD Inc.'s basis in the equipment?
Let's solve this systematically.

Step 1: Does this qualify under IRC §351?
We check the 80% control test. Only transferors of property count. Carlos transferred property (equipment). Diana transferred services, which are not property. Therefore, only Carlos is in the control group. He owns 70 out of the 95 total shares (70 + 25), which is 73.7%. This is less than 80%. The transaction fails the §351 control test.
> ⚠️ Exam trap: > The most common mistake is to group Carlos and Diana together, see they own 100% of the stock, and incorrectly apply the nonrecognition rules of §351. Because Diana only contributed services, she is excluded from the control group, and the test fails.
Since §351 does not apply, the transfer is a fully taxable sale for Carlos.
Step 2: Calculate Carlos's Realized and Recognized Gain
This is now treated as if Carlos sold the equipment to the corporation.
- Amount Realized: $70,000 (FMV of stock) + $5,000 (cash) + $10,000 (debt relief) = $85,000
- Adjusted Basis: $60,000
- Realized Gain: $85,000 - $60,000 = $25,000
- Recognized Gain: Because §351 does not apply, the full realized gain of $25,000 is recognized by Carlos.
Step 3: Calculate Carlos's Basis in His Stock
When a transaction is fully taxable, the shareholder's basis in the stock received is simply its fair market value on the date of the exchange. Carlos's basis in his 70 shares is $70,000.
Step 4: Calculate CD Inc.'s Basis in the Equipment
Because the transaction was taxable, the corporation takes a "cost" basis, which is the asset's fair market value on the date of transfer. CD Inc.'s basis in the equipment is its FMV of $100,000.
And Diana? She must recognize $25,000 of ordinary income for her services, and her basis in her 25 shares is $25,000. The Vory tutor, available 24/7 with a VoraPrep subscription, can help you master these distinctions.
Common Exam Questions and Traps
Let's test your knowledge with a few MCQs modeled after the real exam.
Sample Question 1: Alice and Bob form NewCo, Inc. Alice contributes land (a capital asset) with an adjusted basis of $200,000 and an FMV of $500,000 in exchange for 50% of the stock. Bob contributes $500,000 cash for the other 50% of the stock. The transaction meets the requirements of IRC §351. What is Alice's recognized gain on the transfer?> Explanation: The correct answer is C. Because the transaction qualifies under IRC §351 and Alice received only stock (no boot), she recognizes no gain. Her entire realized gain of $300,000 ($500,000 FMV - $200,000 basis) is deferred.
Sample Question 2: Three individuals form a corporation in a §351 transaction. Each transfers property with an adjusted basis of $50,000 and an FMV of $80,000. In exchange, each receives an equal amount of stock. One of the transferors also receives $10,000 cash. What is the amount of gain that transferor must recognize?> Explanation: The correct answer is D. The transferor's realized gain is $30,000 ($80,000 FMV - $50,000 basis). They received boot of $10,000 cash. Gain is recognized for the lesser of realized gain ($30,000) or boot received ($10,000). Therefore, the recognized gain is $10,000.
Sample Question 3: Transferor A contributes property with an FMV of $100,000 and an adjusted basis of $60,000 to a newly formed corporation in a §351 exchange. The property is subject to a liability of $70,000, which the corporation assumes. What is Transferor A's recognized gain?> Explanation: The correct answer is D. Under IRC §357(c), when liabilities assumed ($70,000) exceed the adjusted basis of the property transferred ($60,000), the excess is a recognized gain. The gain is $70,000 - $60,000 = $10,000. This gain is recognized automatically, even if there is no boot and regardless of the overall realized gain.

Strategic Study Plan for Formation and Capitalization
- System Over Speed: Don't rush calculations. On every practice problem, physically write out the decision tree: 1) §351 test, 2) Realized Gain, 3) Boot & Recognized Gain, 4) Shareholder Basis, 5) Corporate Basis. This builds the right mental muscles for exam day.
- Connect the Concepts: This topic is the starting point for a shareholder's basis, which is critical for understanding distributions and stock sales later. It also connects to the rules for the Qualified Business Income deduction under §199A, which depends on the basis of business assets.
- Final Week Drill: In the last week before REG, do 10-15 formation MCQs daily. Don't just check the answer. For each one you miss, write one sentence explaining the principle you overlooked. Was it the §357(c) liability rule? Did you forget to exclude a service partner from the control group? This active recall is far more effective than passive re-reading.
