How to Pay Less Tax on a Business Sale: 7 Levers Most Owners Don't Use

Seven levers decide how much of a business sale you keep, and nearly all have to be pulled before a letter of intent. A few, qualified small business stock (QSBS) in particular, depend on decisions made years in advance. In my work with owners, the gap between a good outcome and a great one is how many were still available when the deal arrived.

Levers That Spread or Defer the Gain

Installment sales. Spreading payments over multiple years can keep you out of the top federal bracket in any single year. Use it when the buyer is creditworthy and future-year income will be lower.

Employee stock ownership plans (ESOPs). Selling to an ESOP lets C-corp owners defer capital gains indefinitely under Section 1042 if proceeds are reinvested in qualifying domestic securities. Complex and not right for every deal, but worth analysis for owners who care about employees.

Opportunity Zones. Reinvesting capital gains into a Qualified Opportunity Fund defers the original gain and, if held long enough, eliminates gains on the new investment's appreciation. The July 2025 tax law made the program permanent, with newly designated zones and revised rules starting January 1, 2027, so the version that applies depends on when you invest. Use it when the underlying project interests you on its own merits.

Levers That Change What Gets Taxed, and at What Rate

QSBS exclusion. Under Section 1202, gains from the sale of qualified small business stock can be excluded from federal tax up to a per-issuer cap (or 10x basis, whichever is greater). Two regimes now apply. Stock issued before July 5, 2025 needs a hold of more than 5 years, a $10M cap, and gross assets of $50M or less at issuance. Stock issued after July 4, 2025 gets a 50% exclusion after 3 years, 75% after 4, and 100% after 5, with a $15M cap and a $75M gross-asset test. If your company is a C-corp that may qualify, examine this from day one.

Charitable Remainder Trusts. You contribute appreciated business interests before the sale. The trust sells, pays no immediate tax, and returns income to you over time, and part of the contribution generates a charitable deduction. Use it when philanthropy is already part of the plan.

Net Unrealized Appreciation (NUA). If you hold company stock inside a 401(k), distributing it in-kind can convert part of the gain to long-term capital rates. A rollover to an individual retirement account (IRA) leaves all of it taxed as ordinary income later. A narrow rule with specific conditions, and often overlooked.

Year-of-sale Roth conversion. The sale year usually produces unusually high income, so the opportunity is often the years immediately before and after. This is tax planning work, and its payoff compounds over time.

The Takeaway

Your entity type and how long you have held the stock determine which levers are open to you. A C-corp owner five years past issuance has a different menu than a limited liability company (LLC) member deciding this quarter, and deal skill does not change that.

The outcome that hurts most: an owner runs a disciplined process and negotiates a premium price, then finds the five-year QSBS holding period was missed by a few months, or the entity conversion came a year too late. The deal closes at a premium with no exclusion.

If a sale is possible in the next two to five years, a tax projection stress-tested against several of these levers is worth walking through before you call a broker.
