How it works

Note: New Hampshire taxes only interest and dividends (the I&D tax is being phased out). Wages and capital gains are not state-taxed for residents.

ESPP qualifying dispositions

No state-level ordinary income or capital-gain tax in New Hampshire.

ISO exercises

No state AMT or income-tax impact on ISO exercises in New Hampshire.
