⚠️ Estimate only — not financial or tax advice. This calculator provides a simplified estimate based on the inputs you provide. Real tax liability depends on many additional factors including other income sources, deductions, credits, state-specific rules, AMT adjustments, timing of transactions, and changes in applicable law. Results may differ significantly from your actual tax bill. Please consult a qualified CPA or tax professional before making any decisions about exercising stock options, selling equity, or other financial moves.
