Section 1202 QSBS is significantly more generous in 2026, with higher exclusion caps and new tiered holding-period benefits—but eligibility is still easy to lose if your entity structure, asset use, or stock redemptions are mishandled. Our business startup lawyers provide a practical overview of what changed and what founders and investors should be doing now, not at exit.

Higher Exclusion Caps

2026 legislation introduced transformative, taxpayer-friendly changes to Section 1202. If you are issuing or acquiring stock in 2026, you are operating under a significantly enhanced regime compared to just a year ago.

For stock acquired after July 4, 2025, the per-issuer exclusion cap has increased from $10 million to $15 million (or 10 times your basis, whichever is greater).

Tiered Exclusions

You no longer face an all-or-nothing five-year wait. The new law introduces a graduated system for stock acquired after July 4, 2025.

50% Exclusion after a 3-year holding period.

75% Exclusion after a 4-year holding period.

100% Exclusion still requires a 5-year holding period.

Expanded Corporate Eligibility

The size limit for a company to be considered a Qualified Small Business has increased from $50 million to $75 million in aggregate gross assets.

The Golden Rule: You Must Be a C-Corp

Only C-Corporations Qualify for QSBS

QSBS status cannot be elected later. It is a structural requirement. Only domestic C-Corporations can issue QSBS.

LLCs and S-Corps Do Not Qualify

If your business is currently an LLC or an S-Corp, you do not have QSBS.

Strategic Conversion from an LLC

Many founders start as LLCs to take advantage of pass-through losses in the early years. However, to trigger the QSBS clock, you must convert to a C-Corp before your aggregate gross assets exceed the $75 million threshold.

The Valuation Advantage

When you convert an LLC to a C-Corp, your basis in the new stock is generally the Fair Market Value (FMV) of the assets at the time of conversion. Since the law allows an exclusion of 10 times your basis, converting at a $2 million valuation could, in theory, unlock a $20 million tax-free exit later.

Maintaining Eligibility: The Active Business Test

The 80% Asset Requirement

Even if you start as a C-Corp, you must maintain eligibility throughout substantially all of your holding period.

At least 80% of your company’s assets must be used in the active conduct of a qualified trade or business.

Industries That Do Not Qualify

Section 1202 was designed to encourage innovation and manufacturing rather than professional services. Ineligible industries include:

Health, Law, Engineering, and Architecture.

Accounting and Financial Services.

Farming and Hospitality, including hotels and restaurants.

Banking, Insurance, and Leasing.

The Risk of Excess Cash

If you raise a large funding round and leave the cash sitting in passive investments for too long, you might fail the 80% active business test. Strategic redeployment of capital is essential.

The Original Issuance Requirement and Redemption Traps

Stock Must Be Acquired at Original Issuance

To qualify for the exclusion, you must acquire the stock at original issuance. This means you purchased it directly from the company in exchange for cash, property, or services.

Secondary Market Purchases Lose QSBS Status

If you buy shares from a co-founder or an early employee, those shares lose their QSBS status immediately.

Stock Redemption Risks

The IRS carefully monitors companies that repurchase stock and then issue new shares to investors. If the company redeems a significant amount of stock from any shareholder within a specific window around your issuance, the entire round may be disqualified as QSBS. There are limited exceptions for repurchasing shares from service providers who leave the company.

Stacking and Packing: Advanced 2026 Planning Strategies

Stacking Through Trust Planning

For high-growth companies in the Philadelphia region, the $15 million exclusion cap may still feel limiting. Sophisticated founders sometimes use stacking strategies to increase the total available exclusion.

Because the $15 million cap applies per taxpayer, founders may gift shares to irrevocable non-grantor trusts for the benefit of children or other family members. Each trust is treated as a separate taxpayer with its own $15 million exclusion.

Packing the Basis for Larger Exclusions

Because the exclusion is the greater of $15 million or ten times the basis, contributing valuable intellectual property or assets to the C-Corp early in the company’s lifecycle can increase the basis. This planning approach can significantly increase the potential tax-free exit amount while remaining within the $75 million asset threshold.

The Pennsylvania Paradox: State-Level Taxes

Pennsylvania Does Not Follow Federal QSBS Rules

While the federal benefits of QSBS are significant in 2026, Pennsylvania residents face a unique challenge. Pennsylvania is one of the few states that does not currently conform to the federal Section 1202 exclusion.

This means that even if you pay zero federal tax on a $15 million gain, you may still owe Pennsylvania’s flat income tax, currently 3.07 percent, on the entire amount. Proper planning requires preparing for this state-level liquidity event even while optimizing federal tax savings.

Conclusion: Do Not Wait Until the Exit to Plan

QSBS is one of the most valuable tax incentives available to small business owners. At the same time, it is also one of the most fragile. A single poorly timed stock redemption or a failure to file an 83(b) election within 30 days of issuance can permanently destroy your eligibility.
