New Hampshire, unlike most states, does not have a general sales tax. Instead of a New Hampshire sales tax, however, the state charges businesses on their profits. The New Hampshire business profits tax is imposed on the gross profits of businesses with a presence in New Hampshire. Those who have $50,000 or more of gross sales for the taxable year must pay this special New Hampshire sales tax.
File new businesses like corporations with the New Hampshire Secretary of State. In this state, the basic idea is that you need to file at the state level if you are forming one of the following business entities: limited partnership, limited liability partnership, limited liability company, for-profit corporation or nonprofit corporation.
Go to the New Hampshire Corporate Division filing forms page at sos.nh.gov/corporate/Forms.html to select the proper filing forms. You will want to do this step first because it would be the business (using the official New Hampshire business name) that pays the New Hampshire business profits tax (sales tax).
Get a federal employer identification number for your New Hampshire business. EIN numbers are provided by the federal Internal Revenue Service. To research the requirements for an EIN, you can find information on the IRS website at IRS.gov. If you use the search engine on the website, you can look for “EIN requirements” to find out if you need an EIN. For most filers, you will need an EIN if you have employees who draw a salary or if you operate a nonprofit organization.
Complete your New Hampshire sales tax registration.
File your business profits returns. You need to make quarterly estimated payments if the estimate is at least $200, as of 2010. To figure what you owe, you need to know the New Hampshire sales tax rate for these business profits taxes. As of November 2010, the rate is 8.5 percent.
The following are the due dates for these special New Hampshire sales taxes:
Corporations: the 15th day of the third month of the current taxable year
Sole proprietors, partnerships and fiduciary trusts: the same day as corporations but in the 4th month
Nonprofits: the same day as corporations but in the 5th month
Estimated payments are due on the 15th day of the months 4, 6, 9 and 12 of the New Hampshire business’s taxable year.
