How early should I start QSBS planning for my company?

Immediately at formation or any new C-corp investment. QSBS requires the stock to be issued when company assets are under $50 million — once you grow past that, new shares may not qualify. Founders should document QSBS eligibility at each funding round and get confirmation from legal counsel. Retroactive QSBS planning is not possible after the fact.

Can I roll over QSBS gain under Section 1045?

Section 1045 allows you to defer QSBS gain by reinvesting in another qualifying QSBS company within 60 days. You do not pay tax on the rolled-over portion until you sell the new QSBS (or it no longer qualifies). This is useful for serial entrepreneurs who want to defer gains while maintaining the QSBS exclusion potential for the new investment.

What happens if I sell a business that was structured as an LLC?

LLC sales are typically treated as asset sales for tax purposes (since LLCs are pass-through entities). Members receive sale proceeds proportional to their interests, with gain or loss allocated based on tax basis in the LLC interest. No QSBS exclusion applies (QSBS requires a C-corp). A conversion to C-corp before a planned sale could theoretically qualify for QSBS, but timing requirements mean this requires multi-year advance planning.

What is the tax treatment of business goodwill in an asset sale?

Goodwill is a capital asset taxed at long-term capital gains rates when sold (assuming the business was held for more than 12 months). This is often the most valuable component in a professional services or branded business sale. In an asset sale, buyers want to allocate more to depreciable assets (Section 15-year amortization for goodwill); sellers prefer maximum allocation to goodwill (capital gain rate vs ordinary income rate for some other assets).

Can I use tax-loss harvesting to offset a large business sale gain?

Yes. Net capital losses from investment portfolios directly offset capital gains from business sales (both are reported on Schedule D). If you have a large investment portfolio with unrealized losses, systematically harvesting those losses in the year of the business sale can significantly reduce the net taxable gain. Time the business sale and loss harvesting in the same tax year for maximum offset.

Capital Gains Tax on Selling a Small Business: Section 1202 and Other Strategies

Selling a small business can generate the largest single capital gains tax event of an owner’s lifetime — and also presents the most planning opportunities. The structure of the sale (stock versus asset), the Section 1202 Qualified Small Business Stock exclusion (which can eliminate up to 100% of federal gains), and installment sale options can dramatically change the tax outcome on the same business sale.

Asset Sale vs Stock Sale: The Fundamental Tax Difference

Asset sale vs stock sale tax treatment for small business

Sale Type	Seller Tax Treatment	Buyer Tax Treatment	Who Prefers It
Stock sale	All proceeds taxed as capital gain at LTCG rate	No step-up; inherits company’s tax history	Seller — lower tax rates
Asset sale	Gain allocated by asset type: ordinary income for inventory and recaptured depreciation; LTCG for goodwill and appreciated property	Full asset step-up; can depreciate again	Buyer — better tax position
Hybrid (some assets)	Negotiated split	Partial step-up	Both — compromise structure

Section 1202 QSBS: Up to 100% Federal Gain Exclusion

Section 1202 Qualified Small Business Stock (QSBS) provides one of the most powerful capital gains exclusions in the tax code: up to 100% of gain from selling qualified small business stock may be excluded from federal income tax. The requirements are specific but achievable for many small business owners who planned ahead.

Stock must be in a C-corporation (not S-corp, LLC, or partnership)
Must be an original issue — purchased directly from the company, not from another shareholder
Corporation’s aggregate gross assets at time of issuance must be under $50 million
Must hold for more than 5 years
Business must be in a qualifying industry (technology, manufacturing, retail — excludes professional services like law/accounting/finance, hospitality, and several others)
If requirements met: exclude up to $10 million OR 10x basis (whichever is larger) from federal income tax
State exclusion: California and several other states do not conform — may owe state capital gains

📈The Value of QSBS Planning

A founder who owned $500,000 in QSBS that grew to $8 million by the 5-year mark can exclude the entire $7.5 million gain from federal capital gains tax. Without QSBS: $7.5M × 20% federal + 3.8% NIIT = $1.785M in federal tax. With QSBS: $0 federal tax. The gain from planning QSBS compliance from the start can be multi-million dollars.

Installment Sale: Spreading the Tax Over Multiple Years

Structuring the business sale as an installment sale allows you to receive payments over multiple years and pay capital gains tax on each payment as received. This can keep you in lower brackets each year rather than creating one massive high-rate gain. Depreciation recapture (which may apply to business assets) must still be reported in full in the year of sale regardless of payment schedule.
