Unpacking the New QSBS Tax Break

October 28, 2025 - 11 minutes read

Recent legislative changes have delivered a major win for founders, investors, and early employees of small businesses. The “One Big Beautiful Bill” has significantly enhanced the Qualified Small Business Stock (QSBS) tax break, a powerful incentive that can shelter millions in capital gains from federal taxes. These updates create exciting new opportunities for growth, investment, and wealth creation.

For business owners, understanding these changes is not just about compliance; it’s about strategic planning. The updated QSBS rules can make your company more attractive to investors, provide a substantial financial benefit to your founding team, and fuel your next stage of growth. Let’s explore what has changed and what it means for your business.

What is Qualified Small Business Stock (QSBS)?

Before diving into the updates, let’s review the basics. Section 1202 of the Internal Revenue Code allows shareholders who sell QSBS to exclude a significant portion—often 100%—of their capital gains from federal income tax. To qualify, the stock must meet several criteria related to the business structure, industry, company size, and holding period.

Historically, this provision has been a favorite among tech startups and venture capitalists, encouraging investment in promising new C corporations. Now, with recent enhancements, its benefits are accessible to a wider range of businesses.

“Navigating the complexities of QSBS was a challenge, but the team at Cobb CPA provided clear, actionable advice that helped us structure our company to take full advantage of this tax break. It was a game-changer for our early investors and founders.” – Founder, Local Tech Startup

Three Major Enhancements to the QSBS Tax Break

The new legislation introduces three transformative changes that every business owner and investor should be aware of.

1. The Tax-Free Cap Jumps to $15 Million

The most eye-catching update is the increase in the maximum gain that can be excluded from taxes. Previously, a shareholder could exclude up to $10 million in gains from the sale of QSBS. The new law raises this cap to $15 million.

Furthermore, this new cap is indexed for inflation, meaning it will likely continue to rise in the coming years. This 50% increase in the tax-free limit provides a much larger runway for founders and investors to realize tax-free profits from a successful exit.

It’s important to remember that the exclusion is actually the greater of two amounts:

  1. $15 million (for stock issued after July 4, 2025).
  2. 10 times the shareholder’s adjusted basis (the original cost) in the stock.

While many founders have a low basis, this second prong can be incredibly valuable for investors who contribute significant capital. For example, an investor who purchases $2 million worth of qualifying stock could potentially exclude up to $20 million in gains (10 x $2 million), surpassing the flat $15 million cap.

2. Shorter Holding Period for Partial Exclusion

Patience is a virtue, but the new law makes the reward for investing in a small business a bit more accessible. The original rule required a shareholder to hold the stock for at least five years to qualify for the 100% tax exclusion.

The new rules introduce a phased-in exclusion for stock acquired after July 4, 2025, significantly lowering the barrier to entry:

  • Hold for 3+ years: Exclude 50% of the capital gain.
  • Hold for 4+ years: Exclude 75% of the capital gain.
  • Hold for 5+ years: Exclude 100% of the capital gain.

This change offers more flexibility. While the full five-year hold remains the gold standard for a 100% tax-free exit, investors and founders can now realize partial tax benefits in a shorter timeframe. This can be particularly helpful in dynamic industries where acquisition opportunities may arise sooner than expected. Note that stock issued on or before July 4, 2025, is still subject to the original five-year holding period requirement for any exclusion.

3. Expanded Company Size Eligibility to $75 Million

Previously, a company could only issue QSBS if its gross assets were $50 million or less at all times before and immediately after the stock was issued. This limited the pool of qualifying businesses, particularly those in capital-intensive industries.

The new legislation increases this gross asset limit from $50 million to $75 million. Like the exclusion cap, this new asset limit is also indexed for inflation. This expansion means that more mature or well-funded companies can now qualify to issue QSBS, opening the door for them to attract capital with this powerful tax incentive.

A crucial detail is that this test is based on the tax basis of assets (generally, cash plus the historical cost of property), not their fair market value. A company could have a market valuation well over $100 million but still fall under the $75 million gross asset test, making it eligible to issue QSBS.

How These QSBS Changes Benefit Your Business

For companies generating $1 million or more in revenue, these updates are not just abstract tax code changes. They have direct, practical implications for your growth strategy.

Attracting Top-Tier Investors

The enhanced QSBS benefits make your company a more compelling investment. The combination of a higher tax-free cap and a larger eligible company size sweetens the deal for venture capitalists and angel investors. When presenting your business to potential backers, highlighting its QSBS eligibility can be a powerful differentiator that significantly improves your odds of securing funding.

Fueling Growth and Scaling Operations

The higher $75 million asset ceiling allows your business to grow larger without losing its ability to offer QSBS incentives for new funding rounds. You can raise more capital and invest more heavily in infrastructure, technology, and talent while still providing new investors with this valuable tax advantage. This supports a more aggressive growth trajectory and helps you scale your operations effectively.

Rewarding Founders and Key Employees

The QSBS tax break is a massive benefit for you and your early team members. After years of hard work and risk-taking, the ability to cash out up to $15 million completely free of federal tax is a life-changing outcome. This potential reward can be a key motivator and a crucial tool for retaining top talent who receive stock as part of their compensation. The shorter three-year holding period for a partial exclusion also provides a tangible benefit sooner.

Strategic Flexibility with Rollovers

While not a new change, the Section 1045 rollover provision remains a vital part of QSBS planning. If you sell QSBS held for more than six months but less than five years, you can defer the capital gain by reinvesting the proceeds into new QSBS within 60 days. This allows you to “tack” the holding period of your original stock onto the new stock, helping you eventually meet the five-year requirement for a 100% exclusion. This gives you and your investors the flexibility to pivot or take advantage of strategic opportunities without triggering a large tax bill.

Is Your Business Positioned to Benefit?

The updated QSBS rules offer a tremendous opportunity, but navigating the requirements is complex. Your business must be a domestic C corporation, and certain industries like health, law, consulting, and finance are excluded. Meticulous record-keeping is essential to prove the company’s gross assets were below the $75 million threshold at the time of stock issuance.

Proactive planning is key. Waiting until you are ready to sell is too late. Structuring your business correctly from the start and ensuring compliance along the way are critical steps to securing these tax benefits.
