Opportunity Zones for business owners selling a company

Yes, to the extent the sale produces capital gain or §1231 gain that is recognized for federal tax, and the buyer is not a related person. The statute lets a taxpayer defer gain invested in a Qualified Opportunity Fund (QOF) within 180 days¹, and the final regulations confirm that both capital gain and gross §1231 gain qualify while ordinary income does not².

You only need to invest the gain. If you sell a company for $12 million and your stock basis is $2 million, the gain is $10 million, and investing $10 million defers all of it. You can also invest less and defer less. Gain excluded from income under §1202 (qualified small business stock) bears no federal tax, so there is nothing to defer; practitioners generally treat only the taxable remainder as eligible gain. Confirm the split with your adviser. See which capital gains qualify.

For a direct sale, the window starts on the closing date when the gain is recognized. For an installment sale, each payment can start its own 180-day window. For gain passed through a partnership or S corporation, the owner can choose among three start dates^2,12.

Escrows and holdbacks add a timing question. Amounts held back are often reported under the installment method when paid, giving them their own windows. Confirm the treatment of each piece of consideration with your tax adviser. See the 180-day rule.

A stock sale usually produces more eligible gain, because the seller's gain on shares held more than a year is generally all long-term capital gain⁴. An asset sale splits the price among the assets sold: inventory and receivables produce ordinary income, depreciation recapture on equipment is ordinary income under §1245, and goodwill and other capital assets produce capital or §1231 gain⁵. Only the capital and §1231 parts can be deferred².

If a C corporation sells its assets, the gain belongs to the corporation, which can make its own QOF investment within 180 days. If an S corporation or partnership sells, the entity can elect, or each owner can elect with a window starting on the entity's year-end, the sale date, or the unextended due date of the entity's return². See partnership and K-1 gains and section 1231 gains.

In an asset sale, start with the price, subtract basis, then subtract the ordinary income pieces; what remains is the eligible gain.

Growth on the QOF interest after a 10-year hold can then be excluded. The rural figures assume the fund holds at least 90% of its assets in zones made up entirely of rural area¹⁵. The step-up rules for investments after 2026 are summarized by RSM⁸. The $1,500,000 of ordinary income is taxed at ordinary rates in the year of sale either way. For a full model, see the tax savings example.

Each installment payment's gain can be invested within 180 days of receipt, or the seller can elect a single window starting at the end of the tax year^13,14. An installment sale is one where at least one payment arrives after the year of sale; gain is reported as payments are received on Form 6252, but any depreciation recapture is reported in the year of sale, and interest is ordinary income³.

• Seller note: invest the gain portion of each principal payment as it arrives; interest is not eligible.
• Earnout: contingent payments are typically installment payments, each with its own window.
• Escrow release: confirm whether the release is a payment for installment purposes.
• Election out: if you elect out of the installment method, all gain is recognized at closing and one window applies.
• Each investment date starts its own five-year clock for gains invested on or after January 1, 2027.

1. 1.Before signing the LOI, model stock versus asset structures for after-tax proceeds and eligible gain.
2. 2.Have your adviser estimate the eligible gain and list every 180-day start date.
3. 3.Choose a fund and complete diligence before closing; see the fund due diligence checklist.
4. 4.Invest cash for QOF equity within each window and keep proof of the investment date.
5. 5.Elect on Form 8949 for the year of the gain and file Form 8997 every year¹⁰.
6. 6.Set aside cash for the year-five tax and check state conformity.

• Rolling equity into the buyer is not a QOF investment and may be a related-party issue.
• Selling to a related person (20% or more common ownership) makes the gain ineligible¹.
• California does not conform to federal deferral or exclusion¹¹; see state tax treatment.
• The year-five tax is due even though the fund interest is illiquid.
• Sponsor quality matters more than the tax benefit; see the risks of Opportunity Zone investing.
