A founder spends two years developing software before incorporating a startup. When the company is formed, the founder transfers the software to the new corporation in exchange for shares.
That software may have little tax basis, but it could already be worth millions.
The value of the intellectual property (IP) at the time of the transfer can have a significant impact on how much gain the founder may eventually exclude under the Qualified Small Business Stock (QSBS) rules.
There's a catch: a higher valuation can increase the potential QSBS exclusion while also making it harder for the company to qualify.
01Why contributed intellectual property matters for QSBS
Under IRC Section 1202, eligible shareholders can exclude a portion or potentially all of their federal capital gain when selling qualifying stock in a domestic C corporation.
For stock acquired after July 4, 2025, the law provides a phased exclusion based on the holding period:
- 3 years: 50% exclusion
- 4 years: 75% exclusion
- 5 years or more: 100% exclusion
The exclusion is generally subject to a per-issuer limit equal to the greater of $15 million, reduced by eligible gain from the same corporation's stock taken into account in prior years, or 10 times the adjusted basis of qualifying stock sold during the year. The $15 million threshold is subject to inflation adjustments beginning in 2027.
Different limits and holding-period requirements apply to stock acquired on or before July 4, 2025.
The 10-times-basis calculation is particularly important when a founder contributes valuable property instead of cash.
Under Section 1202(i), when property other than money or stock is transferred to a corporation in exchange for shares, the stock's basis for QSBS purposes generally cannot be less than the fair market value of the contributed property.
This special QSBS basis may be substantially higher than the stock's regular tax basis under Section 358.
The timing matters, too. Section 1202(i) generally treats stock received for contributed property as acquired on the exchange date. Founders should not assume that years spent developing software before incorporation count toward their QSBS holding period. Special holding-period rules, including the interaction with Section 1223, require separate analysis in more complex transactions.
02Example: A $3 million IP contribution
Suppose a founder develops software personally and later transfers it to a newly formed C corporation in exchange for shares.
At the time of the transfer, the software has an adjusted tax basis of $100,000 and a supportable fair market value of $3 million.
Assume the exchange qualifies for tax-deferred treatment under Section 351 and the shares otherwise satisfy the QSBS requirements.
For purposes of the QSBS 10-times-basis calculation, the $3 million fair market value could produce a $30 million exclusion limit.
Now suppose the founder sells those shares for $33 million after holding them for more than five years.
The potential tax outcome is:
- $32.9 million: Total gain, based on the $100,000 regular tax basis.
- $30 million: Gain attributable to appreciation after the contribution, potentially eligible for the 100% QSBS exclusion.
- $2.9 million: Appreciation that occurred before the IP was contributed, which remains taxable.
In this simplified example, the $30 million of post-contribution gain falls within the 10-times-basis limit and could be fully excluded from federal income tax.
The remaining $2.9 million of pre-contribution appreciation does not qualify for the QSBS exclusion.
This is an important distinction. The special QSBS basis rule can increase the potential exclusion, but it doesn't eliminate taxable appreciation that occurred before the property was transferred.
03The catch: A higher IP valuation can disqualify the stock
The same fair market value that helps establish the 10-times-basis limitation also matters when determining whether the corporation meets the QSBS gross-assets test.
For stock issued after July 4, 2025, the corporation generally must have aggregate gross assets of no more than $75 million both before and immediately after the stock issuance. The threshold is subject to inflation adjustments beginning in 2027.
For this purpose, contributed property is measured using its fair market value at the time of contribution, even when its regular tax basis is much lower.
Consider a corporation receiving intellectual property worth $72 million and $5 million in cash in exchange for stock.
Those contributions alone would bring its aggregate gross assets to $77 million, exceeding the $75 million threshold.
The newly issued shares would fail the QSBS gross-assets requirement.
The implications can extend beyond that issuance. The test considers the corporation's historical gross assets, so exceeding the applicable threshold can prevent later stock issuances from qualifying even if the company subsequently becomes smaller. Changes in the inflation-adjusted threshold may also affect future eligibility.
This creates a valuation trade-off. A higher defensible IP value may increase the founder's potential exclusion limit, but it also counts toward the corporation's gross-assets test.
04The Section 351 reporting requirement founders often overlook
When a founder transfers personally owned software, patents, or other property to a corporation in exchange for shares, the transaction may qualify for tax-deferred treatment under IRC Section 351.
Generally, Section 351 requires the property transferors to control the corporation immediately after the exchange. Control generally means ownership of at least 80% of the voting power and at least 80% of each class of nonvoting stock.
Shares received solely for services do not count as shares issued for contributed property when applying the Section 351 control test.
This distinction matters when founders receive shares for a combination of intellectual property and services.
Even when the exchange qualifies for tax-deferred treatment, there are reporting requirements.
Under Treasury Regulation §1.351-3, a significant transferor generally must attach a statement to the transferor's income tax return for the year of the exchange. The corporation generally must attach its own statement to its return.
For a privately held startup, a founder who owns at least 1% of the corporation's stock by vote or value immediately after the exchange generally meets the significant-transferor definition.
The required statements include information about the transfer and the aggregate fair market value and adjusted tax basis of the transferred property, determined immediately before the exchange.
The regulation also requires taxpayers to retain records supporting the amount, basis, and fair market value of transferred property, along with relevant information about liabilities involved in the transaction.
What if the value of the software isn't known?
Early-stage intellectual property often has no readily observable market value.
A founder may have developed a prototype or proprietary software before generating meaningful revenue or raising outside capital.
That doesn't mean the property's value is necessarily zero.
The valuation should reflect the facts at the time of the contribution, supported by reasonable contemporaneous evidence. Depending on the circumstances, an independent valuation may be appropriate.
The value reported on a Section 351 statement is still subject to IRS challenge. The potential QSBS benefit depends on the property's actual fair market value, not simply the number reported on the return.
05What if the founder developed the software after incorporation?
Ownership and timing can completely change the analysis.
If a founder personally owns software before forming the corporation and transfers that property in exchange for stock, Section 1202(i)'s contributed-property rules may apply.
But when software is developed after incorporation and belongs to the corporation from the beginning, there may be no separate property contribution.
The company cannot simply assign a higher value to internally developed software and use that amount to increase the founder's stock basis for QSBS purposes.
Founder IP assignment agreements and invention-assignment provisions signed during incorporation can be important in determining who actually owned the intellectual property and whether a separate transfer occurred.
06What founders should consider before contributing IP
The best time to evaluate these issues is before transferring intellectual property into a newly formed C corporation or converting an existing business into a corporation.
Founders should understand who legally owns the IP, whether the intended transaction qualifies for tax-deferred treatment, and whether the property's fair market value could affect the company's QSBS eligibility.
The potential exclusion benefit should be evaluated alongside the gross-assets threshold and the possibility of taxable pre-contribution appreciation.
Accurate valuation and contemporaneous documentation are particularly important because these transactions may not be closely examined until years later, during an acquisition or other exit.
State tax treatment also matters. California, for example, does not conform to the federal Section 1202 gain exclusion.
07Planning for QSBS starts before the exit
For founders contributing valuable intellectual property, decisions made during incorporation can affect the tax treatment of a future sale worth millions.
Establishing ownership, documenting the contribution, and evaluating the property's fair market value early can help prevent difficult questions during an exit.
