QSBS: The Section 1202 Stock Exclusion

Few tax breaks are as powerful for founders and early investors as QSBS Section 1202. Done right, it can let you sell qualified startup stock and exclude a large share — sometimes all — of your capital gain from federal tax.

QSBS (Qualified Small Business Stock) under Section 1202 allows eligible shareholders to exclude a portion or all of the capital gain from selling qualifying C corporation stock held long enough, subject to per-issuer limits and strict requirements.

What is QSBS under Section 1202?

Section 1202 of the Internal Revenue Code rewards people who invest in small, active C corporations and hold the stock for the long term. When you eventually sell, a percentage of your gain can be excluded from federal income tax — and for stock acquired in certain periods, that percentage can reach 100%.

The policy goal is to channel capital into early-stage companies. For founders, employees with equity, and angel investors, QSBS can be the single largest tax benefit of their careers. But the eligibility rules are detailed, and missing even one can disqualify the entire exclusion.

The core requirements for QSBS

To qualify under Section 1202, the stock and the company generally must meet all of the following. These are the conditions where deals most often go wrong.

• C corporation status. The issuer must be a domestic C corporation when the stock is issued and substantially throughout your holding period. LLCs and S corporations don’t qualify (though a conversion to C corp can start the clock).
• Original issuance. You must acquire the stock directly from the company in exchange for money, property, or services — not by buying it from another shareholder.
• Gross asset test. The company’s aggregate gross assets must stay at or below an IRS-defined ceiling at and immediately after issuance. Confirm the current threshold on IRS.gov.
• Active business requirement. At least a substantial portion of assets must be used in a qualified active trade or business.
• Holding period. You must hold the stock for the minimum period set by the statute to claim the full exclusion.
• Qualified industry. Certain fields — including many professional services, finance, farming, hospitality, and mining — are excluded.

Because each requirement carries its own definitions and timing rules, the gain exclusion is best confirmed in advance, not discovered at sale. Review the official guidance on IRS.gov and document your eligibility from day one.

How much gain can you exclude?

The percentage of gain you can exclude depends on when you acquired the stock, because Congress changed the rate over time. The exclusion is also capped per issuer — generally limited to the greater of a fixed dollar amount or a multiple of your basis in the stock.

Do not assume a specific dollar cap or holding period from memory; both have statutory definitions that can change. Verify the current exclusion percentage, the per-issuer dollar cap, and the required holding period on IRS.gov for your acquisition date.

Excluded businesses: who can’t use QSBS

Section 1202 deliberately excludes certain industries from the active-business test. If most of the company’s value comes from the reputation or skill of its people, or from passive assets, it generally won’t qualify. Excluded fields include:

• Health, law, engineering, architecture, accounting, actuarial science, and consulting.
• Financial services, brokerage, banking, insurance, and investing.
• Farming, and businesses involving certain mineral or natural-resource extraction.
• Hospitality businesses such as hotels, motels, and restaurants.

Technology, manufacturing, software, retail, and many product companies typically can qualify, which is why QSBS is so closely associated with venture-backed startups.

Worked example: comparing a sale with and without QSBS

Suppose a founder sells qualifying stock for a $5,000,000 gain, and assume — for illustration only — a 100% exclusion applies and the gain is within the per-issuer cap. The contrast with a non-qualifying sale is dramatic.

The figures are illustrative. Whether you reach a full exclusion depends on your acquisition date, holding period, and the per-issuer cap. State tax treatment also varies — some states conform to Section 1202 and some don’t — so a federal exclusion doesn’t always mean a state exclusion.

Advanced planning: stacking and packing

Sophisticated investors use legitimate strategies to multiply the benefit. The per-issuer cap applies separately to each eligible taxpayer, which opens planning opportunities:

• Stacking — gifting QSBS to family members or non-grantor trusts so each recipient gets their own per-issuer cap.
• Packing — increasing basis before issuance to raise the basis-multiple portion of the cap.
• Rollover under Section 1045 — deferring gain by reinvesting proceeds from QSBS held a shorter period into new QSBS.

These techniques are powerful but technical, and the IRS scrutinizes aggressive structures. They should only be implemented with experienced tax counsel and proper documentation as part of disciplined tax planning.

Why entity choice matters from day one

QSBS only applies to C corporation stock. Founders who launch as an LLC or S corporation for early tax savings can later convert, but the QSBS holding period and gross-asset test generally start at conversion, not at founding. That trade-off — early pass-through savings versus a future QSBS exclusion — is one of the most important early decisions a startup makes.

Whatever structure you choose, you’ll still want to capture every legitimate write-off, so our overview of business deductions covers the costs you can claim while you build toward an exit.

Frequently asked questions

What types of companies qualify for QSBS Section 1202?

Domestic C corporations in active trades or businesses, below the IRS gross-asset ceiling at issuance, generally qualify. Technology, software, manufacturing, and product companies are common candidates. Professional-service, financial, hospitality, farming, and certain extraction businesses are specifically excluded by statute.

Can an LLC issue QSBS?

No. QSBS must be C corporation stock acquired at original issuance. An LLC or S corporation can convert to a C corporation, but the QSBS holding period and gross-asset test generally begin at conversion, not at the company’s original founding date.

How long must I hold QSBS to claim the exclusion?

Section 1202 sets a minimum holding period for the full exclusion. The exact length is defined by statute and can vary with planning provisions, so verify the current requirement on IRS.gov for your acquisition date before assuming you qualify or selling early.

Does QSBS apply to state taxes?

Not always. Some states conform to the federal Section 1202 exclusion, while others do not and will tax the full gain. Because conformity varies and changes, check your specific state’s rules — a federal exclusion does not guarantee state-level relief.

What is the QSBS gain exclusion limit?

The exclusion is capped per issuer, generally at the greater of a fixed dollar amount or a multiple of your basis in the stock. The specific figures and exclusion percentage depend on when you acquired the stock. Confirm the current limits on IRS.gov.
