Open Side Income Tax Calculator →Side income earned in New Hampshire avoids state income tax entirely, making it one of the best states for gig workers, tutors, and anyone with a side hustle. You still owe federal income tax at your marginal rate and self-employment tax (15.3%) if the side income is from self-employment, but the absence of state tax provides a meaningful advantage. For a $20,000 side hustle, that could mean $500-$2,000 more in your pocket versus a state with income tax. Use this calculator to see your true net on side income in New Hampshire.
New Hampshire 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. New Hampshire does tax interest and dividends above certain thresholds, which may affect retirees and investors.
