Open Stock Option Tax Calculator →Exercising stock options in Washington means you avoid state income tax on the spread between exercise price and fair market value (for ISOs at AMT, or for NSOs at ordinary income rates). This can represent thousands of dollars in savings on a significant exercise. Federal tax still applies: NSO exercises are taxed as ordinary income, while ISO exercises may trigger the Alternative Minimum Tax. Use this calculator to model your stock option exercise scenarios with Washington's zero-state-tax advantage factored in.
Washington is one of nine states with no personal income tax. Residents keep every dollar of earnings from state-level taxation, though the state generates revenue through other means such as sales taxes, property taxes, and in some cases severance taxes on natural resources. Washington does impose a 7% tax on capital gains exceeding $270,000, so high-net-worth investors should factor that in.
