Qualified Small Business Stock (QSBS): Planning Before a Sale
If you founded, invested in, or hold equity in a growing C corporation, qualified small business stock may be one of the most valuable tax provisions available to you. Under the Section 1202 exclusion, some or all of the federal gain on a sale of qualifying stock may be excluded from income. The catch is that eligibility depends on facts that are often set years before a sale, and many owners discover the opportunity too late to document it.
For Wisconsin founders, early employees, and investors, QSBS planning is both a tax question and a wealth question. How much you may keep matters, and so does what you do with the proceeds afterward. Below, we explain how the rules work at a high level and the planning steps worth discussing well before a deal.
Start Here: A Complimentary Pre-Sale Wealth and Tax Review
Before you sign a letter of intent, it helps to know where you stand. Compound offers a complimentary, no-obligation pre-sale wealth and tax review. It may include:
Your equity records: when and how shares were acquired, and whether documentation supports QSBS eligibility
Entity history: whether the company has been a C corporation for the relevant period
Estimated tax exposure: how different deal structures may affect what you keep
Your personal balance sheet: investments, retirement accounts, and real estate outside the company
Estate and family goals: how gifting and trusts may fit the timeline

What Is Qualified Small Business Stock?
Qualified small business stock is stock in a domestic C corporation that meets a set of requirements under Section 1202 of the Internal Revenue Code. At a high level, the rules generally look at:
Original issuance. The stock generally must be acquired directly from the company, in exchange for money, property, or services, rather than purchased from another shareholder.
Entity type. The company must be a C corporation. S corporation stock and partnership interests do not qualify, although some businesses convert to C corporation status as part of their planning.
Gross asset test. The company's gross assets must not exceed a statutory limit at the time the stock is issued and immediately after.
Active business test. Most of the company's assets must be used in an active qualified business during substantially all of the holding period.
Excluded industries. Certain fields, including many professional services such as health, law, accounting, consulting, and financial services, as well as some hospitality, farming, and natural resource businesses, generally do not qualify.
Holding period. The stock must be held for a minimum period. Recent law changes created different holding period and exclusion rules depending on when stock was issued, so the issue date matters.
How Does the Section 1202 Exclusion Work?
When the requirements are met, the Section 1202 exclusion may allow a shareholder to exclude part or all of the federal gain on a sale, subject to a per-issuer cap. The exclusion percentage and the cap depend on when the stock was acquired, and annual limits and statutory caps apply. Gain above the cap is generally taxed under the normal capital gains rules.
State treatment is a separate question. Not every state follows the federal exclusion in the same way, so Wisconsin residents and owners who have moved between states should confirm how their state of residence treats the gain.
Because the details are technical and fact specific, QSBS is an area where tax planning before a business sale matters a great deal.
Planning Moves Worth Discussing Before a Sale
Every situation is different, but QSBS planning often reviews:
Documentation. Capitalization tables, board minutes, stock issuance records, and balance sheets at the time of issuance can support a QSBS position. Gathering them early is far easier than reconstructing them during due diligence. Our client accounting services can help keep records organized.
Deal structure. Asset sales and stock sales may produce very different results for QSBS holders. Structure should be evaluated before terms are negotiated. Our business transaction services support owners through this process.
Timing. If the holding period is close, the timing of a closing date may affect eligibility.
Gifting and trusts. QSBS generally keeps its character when gifted, and some families explore transfers to family members or trusts as part of a broader estate plan. These strategies involve complex rules and should be coordinated with an estate attorney.
Rollover options. In some cases, gain from qualifying stock held for a shorter period may be deferred by reinvesting in other qualified small business stock within a limited window.

What Happens to the Wealth After the Sale?
A QSBS exclusion may reduce the tax bill, but it does not answer what comes next. Many founders move from one concentrated position, their company stock, to a large amount of cash in a single day. That shift raises wealth management questions that deserve as much attention as the tax analysis:
A liquidity plan for remaining taxes, near-term spending, and any escrow or earnout uncertainty
Diversification into a portfolio built around your goals, time horizon, and risk tolerance
Income replacement if the company was your primary source of earnings
Charitable and legacy goals, including donor-advised funds and gifts to family

Why Tax and Wealth Planning Should Work Together
QSBS sits at the intersection of entity structure, deal terms, estate planning, and investment strategy. When a tax preparer evaluates eligibility in isolation and a separate advisor manages the proceeds later, opportunities can be missed. Compound brings wealth management, investment management, tax planning and preparation, and business transaction services together, so the planning before a sale and the investing after it are part of one strategy.
Compound works with founders, investors, and business owners throughout Wisconsin, including Milwaukee, Madison, Green Bay, Appleton, Waukesha, and Eau Claire, as well as surrounding areas.

Frequently Asked Questions
What is qualified small business stock?
Qualified small business stock is stock in a domestic C corporation that meets Section 1202 requirements, including original issuance, a gross asset test, an active business test, and a minimum holding period.
Can S corporation owners use QSBS?
S corporation stock does not qualify. Some businesses evaluate converting to a C corporation, but conversion has its own tax consequences and the QSBS clock generally starts only after qualifying stock is issued.
How much gain can the Section 1202 exclusion cover?
The exclusion percentage and per-issuer cap depend on when the stock was acquired, and statutory limits apply. Gain above the cap is generally taxed under normal capital gains rules.
Does Wisconsin follow the federal QSBS exclusion?
State treatment can differ from federal treatment and may change over time. Wisconsin residents should confirm current state rules with a tax professional before a sale.
When should QSBS planning start?
Ideally at formation or when stock is issued, and no later than several years before a sale, so documentation, structure, and estate planning can be addressed in time.
