A starting point for understanding what a business sale will cost in taxes. Adjust the inputs and see federal and California estimates side by side. Use the result to start the planning conversation early enough to matter.

Exit tax planning
Estimate what an exit actually nets you.
Use this as a starting point, not a final answer. We work with owners long before a sale is on the table — adjust the inputs, get a rough number, and schedule a call if it raises questions. Educational illustration only — not tax, legal, or investment advice.

Educational estimate only. This calculator uses simplified assumptions: top federal LTCG rate of 20%, NIIT 3.8%, federal ordinary 37%, California 13.3% (other states as shown above). California’s additional 1% mental health surtax on income over $1M is not modeled. It ignores AMT, other state-specific surtaxes, phase-outs, deductions, credits, and the full QSBS rules. Results are illustrative estimates only — not projections or forecasts — and do not constitute tax, legal, or investment advice. Consult a qualified CPA and adviser before acting on any exit decision. Full calculator assumptions and disclaimer.
