Can I serve myself?

Yes

1. Search name availability with the New Hampshire Secretary of State Search the NH SOS entity database at sos.nh.gov to confirm your desired LLC name is available and not deceptively similar to an existing New Hampshire entity. The name must include a valid designator under RSA 304-C:19. Optional: reserve for 120 days ($15) while preparing documents.
2. Appoint a New Hampshire registered agent Designate a registered agent with a physical New Hampshire street address (no PO boxes), available during normal business hours under RSA 304-C:26. New Hampshire residents may self-serve as RA. Out-of-state owners use a commercial RA service ($50–$150/yr).
3. File the Certificate of Formation ($100) File online via the NH QuickStart portal at sos.nh.gov or by mail to the New Hampshire SOS. Provide the LLC name, registered agent name and NH street address, principal office address, and organizer information. Pay the $100 filing fee. Standard online processing is typically 1–5 business days.
4. Draft an Operating Agreement New Hampshire's LLC Act (RSA 304-C:40) allows members broad flexibility in governing the LLC through an Operating Agreement. Address membership percentages, voting rights, profit and loss allocation, member admission and exit rules, and dissolution procedures. Especially important for multi-member LLCs in NH's tech, healthcare, and professional services sectors.
5. Obtain an EIN from the IRS After the Certificate of Formation is approved, apply for an EIN at irs.gov/ein. The EIN is issued immediately online and is required for bank account opening, payroll, and federal tax filing.
6. Register for New Hampshire business taxes (BPT and BET, if applicable) New Hampshire imposes a Business Profits Tax (BPT) of 7.5% on business profits if gross receipts exceed $92,000, and a Business Enterprise Tax (BET) of 0.55% on enterprise value (compensation, interest, and dividends paid by the business). Register with the NH Department of Revenue Administration at revenue.nh.gov. New Hampshire has no general sales tax, so most goods-selling LLCs do not need a sales tax permit.
7. File the Annual Report each April 1 New Hampshire LLCs must file an Annual Report by April 1 each year via the NH QuickStart portal ($100 fee). The report confirms or updates the LLC's registered agent, principal office address, and member/manager information. Failure to file results in administrative dissolution. Set a calendar reminder each March to file before April 1.

Formation context

Who should form in New Hampshire?

Recommended for

New Hampshire residents and businesses that benefit from no personal state income tax on LLC pass-through income; Southern NH businesses (Manchester, Nashua, Portsmouth) in tech, healthcare, financial services, and professional services seeking tax advantages over Massachusetts; E-commerce, consulting, and remote service businesses with owners who live in NH and want to maximize after-tax LLC income

Tax treatment (default)

Pass-through by default: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). No New Hampshire personal income tax on LLC pass-through income. NH's Business Profits Tax (7.5%) and Business Enterprise Tax (0.55%) may apply at the business level for LLCs with NH activities above the threshold.

New Hampshire is most cost-effective for owners who actually live in New Hampshire and can benefit from the income tax advantage. If you live in Massachusetts and form in NH, you will still owe Massachusetts income tax on your NH LLC's pass-through income as a MA resident. Form in the state where you live, or consult a tax professional.

No publication requirement in New Hampshire — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.

FAQ

Common New Hampshire LLC formation questions

Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.

Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

Missing your annual report deadline triggers late fees and — if left long enough — administrative dissolution, which voids your LLC's liability shield until reinstated. Know your New Hampshire deadline, fee, and the consequences of missing it.

Also see the LLC annual report requirements hub for state-by-state deadlines, fees, late penalties, and reinstatement rules.

If your LLC opens an office, hires employees, or regularly does business in another state, you must foreign-qualify there — or face fines, back taxes, and loss of standing to sue. Our foreign qualification guide covers when you need it, how to file a Certificate of Authority, and what it costs.

Your Articles of Organization are filed — now make your LLC operational. Four actions every new LLC owner needs to take:

Formation gets your LLC into existence; contracts, trademark protection, operating agreement review, and vendor-document review keep it usable. Compare subscription and per-document legal platforms before you rely on a template or pay a local attorney retainer.

Commingling personal and business funds is the #1 way LLC owners lose their liability shield. A separate business account — in your LLC's legal name, with your EIN — is the foundational act of corporate formality. Mercury, Novo, Bluevine, Relay, and Found open same-day with no monthly fees. Compare online banks vs. Chase and Bank of America.

How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.

Single-member LLCs file Schedule C with their personal Form 1040 (due April 15). Multi-member LLCs file Form 1065 by March 15. S-Corp-elected LLCs file Form 1120-S by March 15. Know your form, your deadline, and the common deductions — home office, vehicle, retirement contributions, and startup costs — before your first April filing.
