How to convert your S Corporation into a tax-favored QSBC

By
Industry Observer with Green Krist CPA PLLC 34463

Let’s turn our attention to an increasingly valuable tax planning opportunity involving qualified small business corporation (QSBC) stock, especially in light of recent law changes.

QSBCs—essentially, certain qualifying C corporations—offer powerful tax advantages. Most notably, you may be able to exclude up to 100 percent of the gain on the sale of QSBC stock if you hold it for at least five years. In addition, partial exclusions are now available for shorter holding periods (50 percent after three years and 75 percent after four years), making this strategy more flexible than ever.

There are also generous limits on the amount of gain that you can exclude. Depending on your situation, you may exclude the greater of $15 million (indexed for inflation) or 10 times your investment basis.

Another significant benefit is the ability to defer gains by reinvesting proceeds into other QSBC stock within a specified time frame.

But QSBC status applies only to C corporations—not S corporations. This raises an important question: How can you take advantage if your business currently operates as an S corporation?

There are several potential strategies:

  • Revoking S corporation status to convert back to C corporation status
  • Forming a new C corporation and transferring assets
  • Creating a C corporation subsidiary that qualifies as a QSBC
  • Using an asset “drop-down” structure to shift future growth into a QSBC entity


Each option has unique tax implications, including possible recognition of gains during restructuring. In many cases, only newly issued shares will qualify for QSBC benefits, making timing especially important.

In summary, QSBC planning can provide substantial long-term tax savings, particularly for businesses anticipating significant growth or a future sale.
