Search New Hampshire records

New Hampshire only allows its search on its own site, so this opens in a new tab. It finds the company, not usually its EIN.

What the New Hampshire business search shows

The New Hampshire Secretary of State keeps New Hampshire’s record of companies formed or registered there. Use it to confirm a company’s exact legal name and whether it is active.

The New Hampshire business ID

The New Hampshire Secretary of State gives every company a business ID when it is formed. It identifies the company in state records, and it is not the company’s EIN.

Check if a New Hampshire LLC is active

Search the company in the New Hampshire business search and open its record. The status tells you whether the state counts the company as active. Words such as dissolved, revoked, forfeited, inactive or delinquent mean it is not in good standing, usually because an annual filing or fee was missed, and the company may need to be reinstated before it can do business there.

To prove a company is in good standing to a bank, a lender or another state, order a Certificate of Good Standing from the New Hampshire Secretary of State. Our LLC status check reads the status from public data where a state publishes it.

Good to know in New Hampshire

  • New Hampshire has no general sales tax on goods, so most New Hampshire LLCs never open a sales tax account. The state taxes the business itself instead: the Business Profits Tax on profits, and the Business Enterprise Tax, which is measured on the compensation, interest and dividends a business pays rather than on its profit.
  • New Hampshire taxes an LLC as its own business organization even when the IRS does not. A single-member LLC owned by an individual and disregarded for federal purposes still files its own New Hampshire return, Form NH-1040, the Proprietorship Business Profits Tax return, once it meets the filing requirements; S corporations are likewise taxed the same as C corporations.
  • The Department of Revenue Administration wants a separate identifying number on every business tax return. A single-member LLC that must file and has no EIN of its own has to apply for a Department Identification Number (DIN) through Granite Tax Connect or on Form DP-200, and may not file under the owner's Social Security number in the meantime.
