Hypothetical Case Study: How a Simple Business Pivot Almost Cost a Tech Founder $2.4M in Taxes

A business expansion can affect more than next year's revenue. For a founder holding qualified small business stock, it can also change the facts supporting a future Section 1202 exclusion.

This hypothetical example follows a Houston SaaS founder considering an equipment-leasing expansion. It is not an actual IFP client outcome.

What is the Section 1202 QSBS exclusion?

Section 1202 can exclude eligible gain on qualifying C-corporation stock. The exclusion percentage, holding period and dollar limit depend in part on when the stock was acquired.

The founder in this example acquired qualifying original-issue shares in 2020 and is evaluating an expansion after four years. For those shares, the otherwise applicable 100% exclusion requires a holding period of more than five years. The example assumes a $10 million eligible gain, no prior use of the applicable per-issuer dollar limit, and a basis low enough that the ten-times-basis alternative does not produce a higher limit.

For eligible stock acquired after July 4, 2025, the newer rules provide exclusion tiers of 50% after three years, 75% after four and 100% after five or more, with a $15 million dollar limit indexed for tax years after 2026. The ten-times-basis alternative remains. The separate increase in the corporation's gross-asset threshold to $75 million applies to stock issued after July 4, 2025. The current statute and effective-date notes distinguish these rules.

For related background, see our guide to Section 1202 QSBS and the 2025 tax law.

When can an expansion put the exclusion at risk?

The founder is considering a separate line of business leasing server equipment to third parties. Assume the proposal would allocate 35% of the company's asset value to that excluded leasing activity and leave 65% in qualified SaaS activities, without another statutory rule treating the leasing assets as qualified active-business assets.

That is different from leasing servers for the company's own use or operating a data-hosting service. Neither of those facts, by itself, establishes that a business falls into the statute's excluded leasing category.

Section 1202 generally requires at least 80% by value of corporate assets to be used in the active conduct of one or more qualified trades or businesses. It excludes specified activities, including a leasing business. The overarching active-business requirements apply during substantially all of the stockholder's holding period; a proposed change calls for a review of its scale, duration and actual facts.

In this example, the proposed 65% qualified-asset share would fall below the 80% test while that asset mix persisted. That creates a concrete reason to review the expansion before proceeding, rather than assuming a new lease automatically destroys QSBS eligibility. The governing requirements are in Section 1202(c) and (e).

What should the founder's specialists review?

The CPA and attorney evaluate the proposed activities and asset allocations before the company commits to the new line of business. Their review includes:

• The business actually conducted: Who owns the equipment, who uses it and whether the revenue comes from an operating service or an excluded leasing activity.
• The asset-value test: How assets are valued and used, including any applicable working-capital or other statutory rules.
• The holding-period record: Whether the company has satisfied the relevant requirements during substantially all of the founder's holding period.
• The expansion alternatives: Whether the proposal can be changed without assuming that a new entity or revised contract automatically solves the issue.

For the example's outcome, assume the founder decides not to pursue the excluded equipment-leasing activity inside the issuing company and the company otherwise continues to satisfy the applicable QSBS requirements.

What could the difference mean at sale?

Two years later, the founder sells the qualifying shares after more than five years of ownership. Assume the full $10 million gain qualifies for the applicable 100% federal exclusion.

Under those assumptions, the eligible gain produces no federal income tax. If the gain did not qualify and all of it were instead subject to an assumed 20% long-term capital-gains rate plus 3.8% net investment income tax, the federal tax would be $2.38 million, rounded to $2.4 million in the headline. The comparison excludes state taxes and other transaction-specific effects.

The practical lesson is to review proposed business changes before committing to them, while there is still time to weigh the alternatives.

Plan for what comes after the sale

A business sale changes more than your tax return. It can change how you fund retirement, invest your wealth and support your family.

Integrity Financial Planning helps founders connect their personal investment and retirement decisions to life after the business. The work can include reviewing existing holdings, setting an appropriate portfolio allocation and planning how invested assets will support future spending.
