THE SHORT ANSWER
Use current tax facts to plan a sale, but do not treat them as a prediction of buyer demand or price. IRS guidance does not support a 2026 QBI expiration or a jump to a 39.6% top individual rate. Build scenarios around your business earnings, financing and personal goals, then ask advisors how the actual deal would be taxed.
Replace the supposed tax cliff with verified facts
The IRS confirms that the QBI deduction was made permanent, subject to eligibility and limitations. For tax year 2026, the top individual marginal federal rate remains 37%, and the federal basic estate exclusion is $15 million. These facts contradict a general deadline narrative based on QBI ending and the estate exclusion being halved.
(IRS: business provisions of the 2025 tax law) (IRS: federal tax adjustments for tax year 2026)QBI is not the same as capital-gain treatment. IRS guidance excludes net capital gains from QBI and provides other limitations. Do not calculate a seller’s sale liability by multiplying annual business profit by a headline individual rate.
(IRS: qualified business income deduction)Keep company earnings separate from owner taxes
A change in an owner’s personal income-tax estimate does not by itself change the company’s operating earnings or prove a valuation increase. Begin with a reconciled financial statement and an earnings definition appropriate to the buyer’s operating model.
The SBA describes income, market and asset valuation approaches. Apply supported evidence to the actual business rather than assigning a premium because of a tax-law headline. If you use a forecast, identify its operating assumptions and compare them with historical results.
(SBA: closing or selling a business)Build three owner scenarios
| Scenario | Evidence and decision question |
|---|---|
| Explore a sale now | Current earnings, credible buyer funding and required closing cash |
| Prepare before marketing | Specific gaps, cost to address them and ability to keep operating |
| Remain an owner | Personal capacity, succession plan and business downside exposure |
For each path, keep the same starting accounts and show only the assumptions that change. A realistic sale scenario should include financing conditions, contracts and transition responsibilities as well as price.
Use transaction-specific tax advice when an offer exists
QSBS amendments can affect qualifying stock, but acquisition dates, issuance dates and other conditions control their application. They do not guarantee a new exclusion to every seller or require rejection of every asset offer.
(Public Law 119-21, section 70431)Ask your advisors to compare feasible structures and supply a reserve for each. In the offer comparison, separate closing cash, seller financing and contingent payments. Track any unverified forecast as a sensitivity case rather than a fact. Review the plan when buyer terms or your business results change; there is no universal tax-triggered best month to sell.
Owner questions
Does 2026 create a universal sell-before-taxes-rise deadline?
No. The broad QBI and top-rate cliff claims are contradicted by IRS guidance. A real transaction-specific deadline still needs verification.
Does an owner income-tax change raise business EBITDA?
It does not by itself change operating earnings. Keep the company earnings reconciliation and the owner’s tax estimate separate.
Should a forecast be described as a confirmed market result?
No. Label assumptions and distinguish observed evidence from predictions and causal claims.
