Open Stock Option Tax Calculator →Exercising stock options in New Hampshire 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 New Hampshire's zero-state-tax advantage factored in.
New Hampshire is one of nine states with no personal income tax.
