QSBS: The Tax Break That Can Make Millions in Gain Tax-Free

If you own stock in a qualifying small business and sell it down the road, you may not owe any federal tax on the gain — up to $15 million of it, sometimes more. That's what Section 1202, often called QSBS, does. It's one of the most generous breaks in the tax code, and most owners have never heard of it.

How to qualify

The company has to be a C-corporation (not an LLC or S-corp), and you have to have received the stock directly from the company, not bought it from another shareholder. The company's assets had to be under $75 million when the stock was issued. A few industries don't qualify, including most professional services and financial businesses. You also need to hold the stock for a while: five years gets you the full exclusion, with partial exclusions starting at three years for stock issued after July 4, 2025.

A simple example

Say you hold qualifying stock and sell it for an $8 million gain after five years. Instead of paying capital gains tax on that $8 million, you pay nothing federally. That's roughly $1.9 million kept in your pocket versus the same gain taxed normally.

What if my business isn't a C-corp? Should I convert?

Maybe, but only if a few things line up. An LLC can convert to a C-corp, and the stock issued at that point can qualify going forward. There are two catches. First, only the growth after you convert gets the break. Value you built before converting doesn't count. Second, the holding-period clock starts on the conversion date, not the day you started the business. S-corps take more work: dropping the S election by itself doesn't make your existing shares qualify, so it usually takes a restructuring.

Converting tends to make sense when:

• You expect the business to grow a lot in value.

• You plan to sell in five or more years, ideally as a sale of stock.

• You're reinvesting profits rather than taking them out.

• You're not in an excluded industry, like most professional services.

It usually doesn't make sense if you take most of the profit out each year, because C-corp profits are taxed twice. The same goes if a sale isn't in your plans, or if a likely buyer would want to buy the company's assets rather than its stock. Converting is also hard to undo. Switching back generally means a five-year wait.
