Form a C Corporation Now to Position for a Tax-Advantaged Sale in Three to Five Years
A strategic analysis of Internal Revenue Code Section 1202 and the Qualified Small Business Stock exclusion — updated for the One Big Beautiful Bill Act amendments.
Entrepreneurs who believe there is a realistic possibility they will sell their company within the next three to five years should be thinking about one thing today: entity structure.
The Internal Revenue Code provides one of the most powerful exit planning tools available to founders and early investors through Section 1202, governing Qualified Small Business Stock, commonly referred to as QSBS. If structured properly, stock issued by a qualifying C corporation can allow shareholders to exclude a substantial portion — and potentially all — of their federal capital gain upon sale.

What Changed Under the New Law
Recent amendments under the One Big Beautiful Bill Act introduced a tiered holding period structure for qualified stock acquired after the effective date of the legislation. Under the updated framework:
| Holding Period | Gain Exclusion |
|---|---|
| At least 3 years | 50% |
| At least 4 years | 75% |
| At least 5 years | 100% |
In addition, the per-taxpayer exclusion cap increased to $15 million for qualifying stock, and the aggregate gross asset ceiling for the issuing corporation increased to $75 million.

Why the C Corporation Structure Matters
Section 1202 applies only to stock in a domestic C corporation. It does not apply to:
- LLC membership interests
- S corporation shares
- Partnership interests
To qualify, the stock must be acquired at original issuance, issued in exchange for money, property, or services, issued when the corporation's aggregate gross assets do not exceed the statutory threshold, held for the required statutory period, and issued by a company engaged in a qualified active trade or business.
Entity selection is not simply a tax filing decision. It is an exit planning decision — one that directly determines whether Section 1202's exclusion is available at the time of sale.
The Three-to-Five-Year Planning Window
Historically, founders viewed Section 1202 as a long-term play because the full exclusion required a five-year holding period. The updated tiered structure changes that analysis.
If a founder forms a qualifying C corporation today and issues stock properly, the holding period begins immediately. After three years, a partial exclusion may be available. After five years, a full exclusion may apply if all statutory requirements are satisfied.
Waiting until an investment banker is engaged or a letter of intent is signed often eliminates meaningful planning flexibility.
A founder forms a new domestic C corporation today, receives qualifying original-issuance stock, grows the company significantly, and sells in year 3 for $20 million with a nominal basis.

This is not a deduction. It is an exclusion from federal capital gains tax.
Who Should Consider This Strategy
Section 1202 planning is particularly relevant for founders and investors in these sectors:
Certain service businesses remain excluded under the statute, including law, accounting, health services, consulting, and financial services. Each business must be evaluated under the statutory active business rules.
Why Early Legal Structuring Is Critical
QSBS eligibility can be permanently compromised by structural errors that are difficult or impossible to correct after the fact:
- Improper original issuance
- Excess redemptions
- Exceeding asset thresholds before issuance
- Incorrect equity grant mechanics
- Late conversions from pass-through entities
- Buyers insisting on asset sale structures
Section 1202 is technical. The planning must be intentional from formation and coordinated with tax advisors.

Start the Clock Now
The holding period begins when qualifying stock is issued — not when you receive an offer, not when due diligence starts, and it cannot be restarted once missed.
If you are forming a new company, raising capital, or considering a future exit, now is the time to evaluate whether a properly structured C corporation can position you for maximum after-tax return.
The earlier you plan, the more options you preserve.
