New Hampshire taxes

New Hampshire has no personal income tax for 2025. It taxes businesses instead. The business profits tax is 7.5% of profit and reaches every kind of business, a sole proprietor included, once gross business income passes a threshold. The business enterprise tax is 0.55% of the wages, interest and dividends a business pays out. LLCs and corporations also file an annual report, from $100.

Personal income tax

New Hampshire has no personal income tax. It has never taxed wages, and its Interest and Dividends Tax was repealed for tax periods beginning after December 31, 2024. So 2025 is the first year with no New Hampshire personal return to file at all.

If you filed Form DP-10 for interest and dividends in earlier years, you do not file one for 2025.

Business owners are a different story. New Hampshire taxes the business itself, and that reaches even a sole proprietor. See the sections below.

Sole proprietor

New Hampshire's business profits tax reaches any business carrying on activity in the state, including a sole proprietor with no LLC. It is 7.5% of taxable business profit, but only a business with gross business income above the filing threshold owes it. The statute sets that threshold at $92,000 and raises it every two years for inflation. For tax periods beginning on or after January 1, 2025 it is $109,000.

The business enterprise tax is a second tax on a different base: 0.55% of the compensation, interest and dividends the business pays out, so it can be owed in a year with no profit. What you pay in it can be credited against the business profits tax, so the two are not simply added. A sole proprietor files no annual report.

Single-member LLC

Every New Hampshire LLC files an annual report with the Secretary of State each year, however few members it has. The fee is $100, due April 1, and filing late adds $50. It is owed whatever the business earned.

The LLC also falls under the business profits tax and the business enterprise tax, on the same terms as a sole proprietor: 7.5% of profit once gross business income passes the threshold, and 0.55% of what the business pays out.

Partnership

A New Hampshire partnership files Form NH-1065, the business profits tax return, due the 15th day of the third month after its year ends, so March 15 for a calendar year. That is a month before a corporation's. Unlike most states, New Hampshire taxes the partnership's own profit, at 7.5%, once gross business income passes the threshold.

Where the business enterprise tax thresholds are met, it also files Form NH-BET and pays 0.55% of the compensation, interest and dividends it pays out. A small partnership below the threshold files nothing, except in a year an owner sells an interest in the business: that year a return is required however small it is.

It also files the Secretary of State annual report, from $100, due April 1.

S corporation

New Hampshire does not follow the federal S election. An S corporation files Form NH-1120 and pays the 7.5% business profits tax on its own profit, the same as a C corporation, once gross business income passes the threshold. The return is due the 15th day of the fourth month after its year ends, so April 15 for a calendar year.

It also owes the 0.55% business enterprise tax where its thresholds are met, filed on Form NH-BET, and the annual report fee, from $100, due April 1. In a year an owner sells an interest in the business, a return is required however small the business is.

C corporation

A C corporation files Form NH-1120 and pays the business profits tax at 7.5% of the profit apportioned to New Hampshire, once gross business income passes the threshold. The return is due the 15th day of the fourth month after its year ends, so April 15 for a calendar year. A corporation selling into other states counts only its New Hampshire share, measured by sales alone.

It also owes the 0.55% business enterprise tax where its thresholds are met, filed on Form NH-BET. What it pays there can be credited against the business profits tax. The Secretary of State annual report is at least $100, due April 1; $100 is the confirmed LLC fee, so a corporation should confirm its own.
