Open Marriage Tax Calculator →Marriage tax effects in New Hampshire are limited to federal changes, since there is no state income tax to create additional bonuses or penalties. At the federal level, two-earner couples can face a marriage penalty when their combined income pushes them into higher brackets, while single-earner couples often enjoy a marriage bonus from the doubled standard deduction. In New Hampshire, these effects are purely federal, making the calculation cleaner. Use this calculator to compare your married and single federal tax bills in New Hampshire.
