Will My New Funding Round Kill My QSBS Tax Break?

Is your next funding round about to wipe out one of your biggest tax benefits?

You built your company with an eventual exit in mind. QSBS, or Qualified Small Business Stock, under Section 1202 can allow eligible founders and early employees to exclude substantial gains from federal tax.

But that benefit can be affected by what happens when your company raises more capital.

The One Big Beautiful Bill Act (OBBBA) changed the QSBS rules in 2025. For qualifying stock issued after July 4, 2025, the gross assets limit increased from $50 million to $75 million, while the maximum exclusion increased from $10 million to $15 million per person. The law also changed the traditional five year holding requirement to a tiered 3, 4, or 5 year schedule.

The bigger tax benefit comes with a reason to pay closer attention to your funding round.

The $75 Million Test Is About Assets, Not Valuation

One of the easiest QSBS concepts to misunderstand is the gross assets test.

The $75 million figure is not your company’s valuation.

It is not your annual revenue.

The test looks at the company’s total assets, measured at cost, immediately before and immediately after the relevant stock issuance. That can include cash and property reflected on the company’s books.

This makes the timing of financing important.

Imagine your company has $50 million in existing assets and closes a $30 million funding round.

Once the new cash arrives, the company’s gross assets could reach $80 million.

That is above the $75 million threshold.

The financing itself therefore needs to be analyzed before closing rather than after the money reaches the company’s bank account.

Every New Stock Issuance Can Require Another Check

QSBS qualification is not something you simply confirm when the company is incorporated and then forget.

The gross assets test needs to be considered at each relevant stock issuance.

If the company is above the applicable threshold immediately after an issuance, the newly issued shares can fail to qualify. Earlier qualifying shares are not automatically disqualified simply because a later issuance does not qualify.

That creates an important distinction for founders who have received stock at different times.

Your company can have multiple share tranches subject to different QSBS rules.

You need to know which shares were issued under which regime.

July 4, 2025 Created Two Important Share Regimes

The 2025 changes mean founders with stock issued across the July 4, 2025 cutoff need to keep careful records.

For stock issued before July 4, 2025, we have the older framework:

$50 million gross asset limit, $10 million exclusion, and five year holding period.

For stock issued after July 4, 2025, the updated framework provides:

$75 million gross asset limit, $15 million exclusion, and a tiered 3, 4, or 5 year holding period.

This means you should not assume every share you own receives the newer treatment.

The issuance date matters.

Your Financing Structure Can Affect the Outcome

The amount of capital you raise is not the only consideration.

Timing and deal structure can matter too.

There are several ways founders may structure a financing when they are approaching the gross asset limit. A smaller initial tranche, a delayed second closing, or straight equity instead of a large upfront SAFE stack may affect where the company stands at the relevant issuance.

This does not mean a particular structure will automatically preserve QSBS eligibility.

It means the funding structure should be reviewed before the transaction is finalized.

A financing that looks straightforward from an investor perspective can have tax consequences for the company’s shareholders.

Common Founder Mistakes

• Treating QSBS as a one-time check: Founders may confirm QSBS eligibility when they incorporate and assume the issue is settled permanently. But the gross assets test needs to be considered again when new stock is issued. A company that qualified years ago can face a different result when a later financing pushes its assets above the applicable threshold.
• Mixing up old and new share tranches: Founders with shares issued before and after July 4, 2025 may accidentally apply the newer $15 million exclusion or shorter holding period to all their shares. The rules differ based on when the stock was issued, so the company’s capitalization records need to distinguish the separate tranches.
• Letting the financing push gross assets above $75 million without modeling the result: The fundraising process naturally focuses on valuation, ownership, and how much cash the company needs. Founders can overlook what the new money does to gross assets immediately after closing. If the company crosses the applicable threshold at issuance, the new shares can be permanently disqualified.
• Waiting until after the round closes to review QSBS: Once the financing has closed and the cash has arrived, the opportunity to change the structure may already be gone. Founders who are approaching the $75 million threshold should model the post-closing assets before signing and discuss whether the timing or structure of the financing creates a better result.

10-Minute QSBS Self-Check

Before closing your next funding round, ask:

• What are the company’s current aggregate gross assets?
• What will gross assets be immediately after the financing closes?
• Which of my shares were issued before July 4, 2025?
• Which shares were issued after that date?
• Am I applying the correct exclusion amount and holding period to each share tranche?
• Is there a financing structure that should be reviewed if we are close to the $75 million threshold?
• Has someone outside the deal team reviewed QSBS eligibility before we sign?

If you cannot answer these questions, pause before closing the round and determine where your gross assets will land.

Bottom Line

QSBS can provide one of the most valuable federal tax benefits available to eligible founders and early employees.

But the benefit is easy to overlook during a financing.

The 2025 OBBBA changes increased the gross assets threshold to $75 million and the maximum exclusion to $15 million for qualifying stock issued after July 4, 2025, while also introducing a tiered holding period.

The important point is to check the numbers before the round closes.

Know your current assets. Model the post financing position. Track your stock issuance dates. And review the structure if you are approaching the threshold.

A few hours of planning before the wire arrives can matter far more than discovering a QSBS problem after the financing is complete.
