50 common QSBS questions founders ask before speaking with an advisor.

QSBS means qualified small business stock. It is stock that may receive special federal gain exclusion treatment under Internal Revenue Code Section 1202 when company-level, shareholder-level, stock-issuance, holding-period, and other rules are satisfied. The facts should be reviewed with a qualified professional before anyone relies on the treatment.

Section 1202 is the Internal Revenue Code provision that covers gain exclusion for certain small business stock. It is the main federal rule people usually mean when they talk about QSBS.

Founders care because the potential federal tax difference on an exit can be material. QSBS review is usually most useful before formation, before issuing stock, before major financing, and before a sale process.

No. Size is only one part of the review. Entity type, original issuance, business activity, gross assets, redemptions, holding period, shareholder type, acquisition date, and state treatment can all matter.

No. QSBS.ai is for founder preparation only. Not tax or legal advice. QSBS.ai does not provide tax, legal, accounting, investment, or financial advice and does not determine QSBS eligibility.

Section 1202 focuses on stock issued by a domestic C corporation. LLC, partnership, S corporation, foreign parent, and conversion histories should be reviewed carefully because timing and entity classification can affect the analysis.

An LLC interest is not stock. If an LLC converts into, or elects to be taxed as, a C corporation, the timing, documents, asset basis, and stock issuance history become important review items.

S corporation status is a common warning area because Section 1202 focuses on C corporation stock. A professional should review any S corporation history, conversion date, and stock issuance sequence.

The gross assets test looks at the issuing corporation’s aggregate gross assets around the time the stock is issued. Many older QSBS discussions refer to a $50 million threshold, while current rules added a $75 million threshold for stock acquired after July 4, 2025.

Later growth does not automatically erase the need to review the original issuance. The important issue is usually whether the corporation met the relevant gross assets requirement before and immediately after the stock issuance being reviewed.

Gross assets generally involve cash and the adjusted basis of other property, with special rules for contributed property. Financings, conversions, asset contributions, and subsidiaries can make this more technical than a simple valuation question.

A common Section 1202 issue is whether at least 80% by value of the corporation’s assets are used in the active conduct of one or more qualified trades or businesses during the relevant period.

Sensitive categories include certain service fields, financial services, banking, insurance, financing, leasing, investing, farming, natural resources, hotels, motels, restaurants, and businesses where reputation or skill of employees is a principal asset.

Yes, these companies are commonly reviewed for potential QSBS treatment. The answer still depends on the actual business model, revenue activity, intellectual property, services component, entity history, and stock issuance facts.

Yes. Research, experimentation, startup activity, intellectual property, regulatory stage, and asset use can all matter. Health service activity should be separated from product, technology, or research activity during review.

Yes. These businesses can be part of a QSBS review, but the details matter. The review should look at active business use, inventory or asset facts, company structure, issuance timing, and whether any excluded activity is present.

Professional-services and consulting businesses are sensitive under Section 1202. The review should focus on whether the business is primarily a product or technology company, a service business, or a reputation-and-skill-driven business.

Original issuance generally means the stock was acquired directly from the issuing company, or through an underwriter, rather than bought from another shareholder. Stock received for money, property, or services can be relevant.

Yes. Founder shares are often central to QSBS review because they are usually issued early and directly by the company. Formation documents, purchase agreements, board approvals, payment records, and vesting terms should be gathered.

Options need special attention because holding period and stock ownership generally connect to exercise, not merely to the option grant. Exercise date, strike price, payment, and the issuing company’s facts at exercise can matter.

For options, the holding-period review usually focuses on when actual stock is acquired, which is commonly exercise rather than grant. Option holders should confirm the timing with a qualified professional before relying on any date.

Restricted stock can be relevant because actual stock may be issued while vesting restrictions still apply. The grant documents, stock purchase agreement, vesting schedule, payment records, and any Section 83(b) election should be reviewed.

RSUs are more complicated because they are often a promise to deliver stock later. The review should focus on when stock is actually issued, the company’s status at that time, and the shareholder’s tax reporting facts.

SAFEs and convertible notes are not usually stock until they convert. The conversion event, stock issuance date, purchase agreement, company asset position, and investor-level facts should be reviewed.

Secondary purchases are a common problem area because Section 1202 focuses on original issuance by the company. A professional should review whether any exception, exchange, or special rule applies.

Yes. Certain stock repurchases by the corporation around the time of issuance can damage QSBS treatment for the stock being reviewed. This is why financing, buyback, tender offer, and founder repurchase history should be collected.

No. A Section 83(b) election does not by itself create QSBS treatment. It can still be an important document because it may help establish tax timing for restricted stock and founder stock.

For stock acquired on or before July 4, 2025, QSBS discussions usually focus on a more-than-five-year holding period for the main exclusion. For stock acquired after July 4, 2025, current rules added tiered exclusion percentages after 3, 4, and 5 years.

A sale before the relevant holding period can reduce or eliminate the available Section 1202 benefit. Section 1045 rollover planning may be worth discussing if the stock was held for more than six months and replacement stock is acquired on time.

Section 1045 can allow gain deferral when QSBS is sold after more than six months and proceeds are reinvested into other qualified small business stock within the required 60-day window. This is technical and should be handled with an advisor.

Some exchanges, reorganizations, conversions, and acquisition structures may allow holding-period or basis history to carry over, but the answer is transaction-specific. Deal documents should be reviewed before signing or closing.

An IPO does not automatically erase the stock’s history. The key review usually looks back to original issuance, company status at issuance, holding period, and whether later transactions changed the stock or shareholder facts.

A merger or acquisition can change the analysis. Cash, rollover equity, stock consideration, reorganization structure, and replacement stock can all affect the final tax review.

Yes. Tender offers and secondary sales can involve partial exits, issuer repurchases, or sales before a holding-period milestone. The documents should be reviewed before deciding what to sell and when.

Gifts, inheritances, partnership distributions, and some transfers can have special holding-period and basis rules. Transfers should be planned before they happen, especially when trusts or family members are involved.

The classic limit is generally the greater of $10 million or 10 times basis for older stock. Current rules added a $15 million dollar limit for stock acquired after July 4, 2025, with later inflation adjustments. The final amount depends on dates and facts.

The limitation is generally applied by taxpayer and by issuing corporation. Married filing status, trusts, partnerships, gifts, and multiple issuances can make the calculation more complex.

The dollar cap is a fixed per-issuer exclusion limit. The 10-times-basis cap is tied to the taxpayer’s adjusted basis in the stock sold. Which limit matters depends on the amount invested, acquisition date, and gain amount.

Not always. Federal Section 1202 treatment and state tax treatment can differ. Some states conform, some partially conform, and some do not follow the federal exclusion in the same way.

AMT and net investment income tax treatment can depend on acquisition date, exclusion percentage, and other taxpayer facts. This is a tax-return-level question for a qualified professional.

Some planning uses trusts, gifts, or family transfers, but this is complex and can create tax, legal, estate, gift, and anti-abuse issues. It should not be done from a generic FAQ alone.

Useful documents include incorporation records, stock purchase agreements, option and exercise records, cap tables, board consents, financing documents, 83(b) elections, tax returns, financial statements, acquisition documents, and state residency history.

The cap table can help identify issuance dates, shareholder names, share classes, option exercises, conversions, transfers, repurchases, and financing rounds. It is usually one of the first documents an advisor will request.

A 409A valuation is not a QSBS document by itself, but it can help show equity value, option exercise context, compensation timing, and company-stage facts that may support a broader review.

Formation documents can show the corporation’s legal form, incorporation date, authorized stock, founder issuances, stock approvals, and early ownership history.

Financing documents can show gross assets before and after issuance, preferred stock terms, investor stock issuance, SAFEs or note conversions, redemptions, and company representations about QSBS.

Business activity documents help advisors understand whether the corporation used its assets in active business operations and whether sensitive service, financing, leasing, investing, restaurant, hotel, farming, or resource-extraction activity is present.

It can. State residency, sale timing, state conformity, source rules, and prior-year filings may all matter. Founders who moved states before an exit should raise this early with a tax professional.

Often yes. Investors may focus on original issuance, fund or partnership reporting, and Section 1045. Employees often focus on options, exercises, restricted stock, RSUs, and employment-related documents. Founders usually focus on formation, stock issuance, and exit planning.

Speak with a qualified professional before forming or converting the company, issuing stock, exercising options, raising a large round, doing a tender offer, selling the company, gifting shares, creating trusts, or attempting a Section 1045 rollover.
