Section 1202 QSBS Exclusion for Manufacturing Owners
An Idaho fabricator sells the business after 20 years and walks away with $12 million of gain on the transaction. Under the general capital gains rules, that gain triggers roughly $2.4 million in federal tax at the 20 percent long-term rate, before state tax and Net Investment Income Tax. Under Section 1202, the same seller could pay zero federal capital gains tax on much of that gain if the company was structured as a C corporation and the owner held the stock for at least five years.
Section 1202 is one of the most valuable planning tools in the code for a growing manufacturer, and it is one of the most commonly missed. Owners routinely form as LLCs or S corporations because those structures work well while the company is operating, then discover at sale time that they left a seven or eight figure exclusion on the table.
What §1202 Excludes and Why It Matters at Sale
Section 1202 excludes from federal income tax the gain on the sale of Qualified Small Business Stock (QSBS) held for more than five years. For stock acquired before September 27, 2010, the exclusion is 50 percent. For stock acquired between September 28, 2010 and July 4, 2025, the exclusion is 100 percent. The One Big Beautiful Bill Act created a tiered exclusion for stock acquired after July 4, 2025: 50 percent at three years of holding, 75 percent at four years, and 100 percent at five years.
The cap is the greater of $15 million per issuer (raised from $10 million by OBBBA, for stock acquired after July 4, 2025) or 10 times the taxpayer’s aggregate adjusted basis in the QSBS. The cap applies per shareholder, per issuer.
The Qualified Small Business Test
To issue QSBS, a company must be a domestic C corporation and must have aggregate gross assets of no more than $75 million at all times before and immediately after the stock is issued (raised from $50 million by OBBBA, for stock acquired after July 4, 2025). The gross assets test uses cash and the adjusted basis of other property. Post-issuance growth beyond the ceiling is allowed. Companies that exceeded the ceiling before issuance are permanently disqualified from issuing QSBS.
Which Manufacturing Activities Qualify
Section 1202 requires an active business use test: the corporation must use at least 80 percent of its assets in a qualified trade or business. Manufacturing squarely qualifies. So do most industrial and technical businesses.
Excluded activities include most services provided by health, law, engineering, architecture, accounting, actuarial, and consulting firms, plus banking, insurance, financing, farming, natural resource extraction, and hospitality. For a pure Idaho or Utah manufacturer, this is not a hard test. For a hybrid business that mixes production with a significant service or resale component, the 80 percent line becomes worth documenting.
The 5-Year Holding Period Requirement
The holding period starts on the date the stock was originally issued to the taxpayer. Stock acquired through a §351 tax-free contribution takes a tacked basis and holding period from the contributed property. Stock received in a §1045 rollover from prior QSBS gets its own tacked holding period.
Sales before five years do not get the full exclusion, but §1045 allows a rollover of gain into replacement QSBS if reinvested within 60 days. For a manufacturer approaching a sale before the five-year mark is hit, a §1045 rollover into new QSBS can preserve the exclusion track for a subsequent sale.
Original Issuance and C-Corporation Requirements
QSBS must be acquired at original issuance in exchange for cash, other property (not stock), or services. Secondary market purchases from other shareholders do not qualify. The company must be a C corporation at the time the stock is issued and generally must remain a C corporation for substantially all of the five-year holding period.
Planning Moves for LLCs and S-Corps
Most family manufacturers are formed as LLCs or S corporations for operational flexibility and single-level tax on operating income. A conversion to C corporation before a planned sale can start the QSBS clock, but it locks in double taxation on operating income during the holding period and forfeits the built-in S corporation earnings from QSBS eligibility.
The decision is a real trade-off: C corporation double tax on operating profits for five years, in exchange for the exclusion on up to $15 million (or 10x basis) of gain at sale. For a business with a defined sale window, real growth ahead, and moderate operating profit relative to eventual sale value, the math often favors the conversion.
QSBS is one of the highest-leverage tax planning tools available to a growing Idaho or Utah manufacturer, and it has to be structured in advance. The manufacturing team at Cooper Norman has run the model for family-owned producers considering C corp conversion, §1045 rollovers, and gift planning that stacks §1202 caps across family members. If you are within a five to seven year window of a possible sale, our valuation and transition planning group is the right first call.
