New Hampshire has no income tax on wages, but every business organization with gross business income above $109,000, corporations, LLCs and sole proprietorships alike, files the business profits tax, and those with gross receipts above $298,000 the business enterprise tax on the wages, interest and dividends they pay. The state does not recognize S corporation status, so an S corporation files as a corporation. One return covers both taxes, due by the 15th day of the fourth month after the year ends. The line is shown from the $100,000 revenue band; a business below the threshold files nothing.
