Getting an EIN in New Hampshire is free, runs online through the IRS EIN Assistant, and finishes the same day, as of 2026. With no sales tax and no wage income tax, that federal number does most of the work for a small LLC. Start your New Hampshire LLC first, so the name matches your CP 575.
New Hampshire EIN: Cost, Process, and Who Needs One
A New Hampshire LLC gets its EIN free from the IRS, applied for online through the EIN Assistant and issued the same day; because the state levies no wage income tax and no general sales tax, that federal number is usually the only tax ID a small LLC needs at first.
- Cost: free directly from the IRS. Third-party filing services charge $150 to $300 for the identical number.
- Where to apply: the IRS online EIN Assistant issues the number on screen the moment you finish; no SSN means filing Form SS-4 by fax or mail instead.
- Timing: same day online, roughly four business days by fax, about four weeks by mail.
- Who needs one: multi-member LLCs, any LLC with employees, and any LLC electing S-corp or C-corp taxation. Solo LLCs can skip it but rarely should.
- State taxes: register with the New Hampshire Department of Revenue Administration only if the Business Profits Tax or Business Enterprise Tax applies. There’s no sales tax permit here.
- Contacts: IRS Business and Specialty Tax Line, 800-829-4933, weekdays; international applicants with no U.S. presence call 267-941-1099.
Does Your New Hampshire LLC Need an EIN?
Whether the IRS requires an EIN comes down to your LLC’s structure and whether you’ve hired anyone. A single-member New Hampshire LLC with no employees is a disregarded entity, so it isn’t federally required to have one. Most owners get it anyway, because banks ask for it and it keeps an SSN off vendor forms.
| Business type | EIN required? | Notes |
|---|---|---|
| Single-member LLC, no employees | No (recommended) | Disregarded entity; needed for a business bank account |
| Single-member LLC with employees | Yes | Payroll and federal deposits require it |
| Multi-member LLC | Yes | Taxed as a partnership by default |
| LLC electing S-corp or C-corp | Yes | The election runs on the EIN |
| Sole proprietor (no LLC) | Only with employees | SSN works otherwise |
| Partnership | Yes | Always required |
If two or more people own the company, lock the ownership split into a New Hampshire operating agreement before filing, since the responsible party on the application should reflect who actually controls the LLC.
How New Hampshire LLCs Apply for an EIN Online
The online route is the one nearly everyone should use, and it’s the fastest by far. In Aaron Kra’s experience filing across more than 25 states, the entity-classification screen is where New Hampshire applications stall most often, so slow down there.
- Confirm the LLC is approved: Your name has to match the New Hampshire Secretary of State record exactly, or the CP 575 won’t line up with your formation paperwork.
- Open the EIN Assistant: The IRS online EIN Assistant runs Monday to Friday 6 a.m. to 1 a.m. ET, Saturday 6 a.m. to 9 p.m. ET, and Sunday 6 p.m. to midnight ET.
- Choose the entity type: Pick the option matching how the LLC is taxed; this screen forces the most refilings.
- Enter the legal name and any trade name: Use the exact LLC name first, then add a DBA only if you registered one.
- Name the responsible party: This has to be a natural person with an SSN or ITIN, never another company.
- Submit and save the CP 575: Download it the instant it appears, because the IRS won’t mail a second copy.
Active typing takes only a few minutes, but the assistant can’t be saved and times out after fifteen minutes of inactivity, so don’t wander off mid-application. You can request one EIN per responsible party per day. That pace matters less than how long a New Hampshire LLC takes to form, which is the real gating step.
No SSN or ITIN rules out the online tool; file Form SS-4 by fax (about four business days) or mail (roughly four weeks), or call the international line. The EIN itself costs nothing, unlike what a New Hampshire LLC costs to form, which carries a real state filing fee.
New Hampshire EIN Approval: Save Your CP 575 Before You Use Any State Account
When the IRS approves your New Hampshire EIN online, the confirmation appears right away as a CP 575 letter. Save or print it before leaving the EIN Assistant, because this letter is the clean proof banks, tax accounts, and licensing agencies may ask to see later.
The CP 575 is your federal EIN confirmation, not a New Hampshire tax account number.
Match the LLC name on this letter to your New Hampshire Secretary of State record before you use it. If the name, responsible party, or entity details look wrong, fix the issue before opening bank or state tax accounts.

Want the New Hampshire LLC and EIN steps handled in one cleaner flow?
The EIN is free from the IRS, but the filing still needs to match your New Hampshire Secretary of State record before you use it for banking, Granite Tax Connect, payroll, or other registrations. Bizee can help with New Hampshire LLC formation and optional EIN filing support, so the legal name, responsible party, and CP 575 record stay aligned from the start.
What New Hampshire LLC Owners Need Before Applying
Pulling a few details together first keeps the whole thing to one clean session. The IRS won’t save your progress, so it pays to have everything in front of you.
- Approved LLC legal name, matching the New Hampshire Certificate of Formation
- The Secretary of State business ID and formation date
- The responsible party’s full name and SSN or ITIN
- How the LLC is taxed: single-member, partnership, or a corporate election
- A reason for applying and a New Hampshire business address
Not sure of your exact registered name? Search the New Hampshire business name database and copy the spelling exactly, then keep a New Hampshire registered agent current so state notices reach you. Forming the LLC before applying keeps the federal and state records lined up, so you’re not redoing anything.
EIN vs Your New Hampshire DRA Tax Account
The EIN is federal; New Hampshire’s business tax accounts are separate, and there are fewer of them than almost anywhere else. There’s no state income tax ID and no sales tax permit, which throws owners coming from Massachusetts.
The accounts that do exist run through the New Hampshire Department of Revenue Administration and NH Employment Security, and they don’t switch on until a specific tax or payroll trigger applies.
| Number | IRS EIN (federal) | New Hampshire accounts |
|---|---|---|
| Issued by | Internal Revenue Service | NH Department of Revenue Administration; NH Employment Security |
| Used for | Federal taxes, payroll, banking | Business Profits Tax, Business Enterprise Tax, unemployment, Meals and Rentals |
| Who needs it | Most LLCs | Only LLCs over a tax threshold, with employees, or selling meals or rentals |
| Where to get it | irs.gov | Granite Tax Connect; NHES |
Half the New Hampshire owners who email me have already handed a filing service around $250 for an EIN they could’ve gotten free in one sitting. I get why. The IRS site isn’t pretty, and the upsells look official.
- Get the EIN directly from the IRS for free.
- Open the business bank account once the EIN is in hand.
- Skip chasing state numbers you don’t actually need yet.
Registering for New Hampshire Business Taxes After Your EIN
Here’s the thing about New Hampshire: the state layer is light, but it isn’t empty. Your EIN unlocks a short list of registrations, and which ones apply depends on what the LLC does and earns.
No sales tax, no wage withholding. The state runs neither, so don’t waste time hunting for a seller’s permit or a withholding account. That alone clears the two registrations most LLCs in other states tackle first.
The Business Profits Tax and Business Enterprise Tax both run through the DRA on its Granite Tax Connect portal. The BPT kicks in once gross business income tops $103,000, and the BET applies above $281,000 in gross receipts or enterprise value tax base.
Every spring, someone in New Hampshire emails me certain they owe nothing because the state has no income tax, then learns their LLC crossed the Business Profits Tax line and owes a return. One contractor I worked with, grossing about $140,000, got hit with a BPT bill he’d never set aside a cent for. It’s a gut punch when it lands in April.
- Do not wait until filing season to check your exposure.
- Open Granite Tax Connect as soon as your income starts approaching the threshold.
- Set money aside along the way, not after the bill arrives.
Once you hire, register with New Hampshire Employment Security for an employer account. State notices about your unemployment rate land at the registered address, so keep an eye on it.
Restaurants, short-term lodging hosts, and vehicle-rental operators also need a Meals and Rentals license from the DRA before collecting. The old Interest and Dividends Tax was fully repealed as of 2025, so it’s off the table for 2026.
None of this replaces your New Hampshire LLC’s annual report, which is a separate Secretary of State filing. Owners weighing whether to handle everything solo can compare New Hampshire LLC formation services before deciding.
EIN and State Tax Mistakes New Hampshire LLC Owners Make
The costliest mistakes here are local, not generic. They cluster around what New Hampshire does differently from the states next door.
- Treating “no income tax” as “no state tax”: The BPT and BET still catch profitable LLCs that assumed they’d never file anything in Concord.
- Skipping the Meals and Rentals license: A new café or short-term rental host who collects before registering with the DRA is already out of compliance.
- Waiting for a state EIN that never comes: New Hampshire issues no general state tax number, so owners who hold off on banking stall their setup for nothing.
- Name mismatches with the formation record: A CP 575 that doesn’t match the Secretary of State Certificate of Formation creates bank and registration friction.
- Filing for a duplicate EIN after restructuring: A name or address change uses Form 8822-B and a tax-classification change uses Form 8832, not a brand-new application.
That last one’s worth flagging, because a second EIN can split your tax history and confuse the DRA when it tries to match returns to a single number.
Recovering a Lost EIN and Updating Your New Hampshire LLC
Losing the number isn’t a crisis, because it’s recorded in several places. There’s no need to reapply, and usually no need to call anyone.
Check the CP 575 first, then a prior federal return, the business bank file, or old payroll records. If none of those surface it, request a 147C verification letter from the IRS by phone; the full walkthrough on how to track down a misplaced EIN runs through each source in order.
A fresh EIN is required only for structural shifts, like a sole proprietorship becoming an LLC, or a single-member LLC adding a partner and turning into a partnership. Routine updates don’t qualify: report a name or address change on Form 8822-B, and note that your New Hampshire DRA account number stays tied to the same federal ID.
New Hampshire EIN Frequently Asked Questions
A handful of questions come up over and over from New Hampshire owners, almost all about the state’s unusual tax setup. The answers below stick to what actually changes your next step.
Does my New Hampshire LLC need a state tax ID if there’s no income or sales tax?
In most cases, no. New Hampshire issues no general state tax ID, so your federal EIN handles banking and federal filings on its own. You open specific state accounts only when a tax applies: a BPT or BET account with the DRA above the thresholds, an employer account with NH Employment Security once you hire, and a Meals and Rentals license if you sell food or lodging.
Do I have to register for the Business Profits Tax or Business Enterprise Tax?
Only above the filing thresholds. The BPT starts once gross business income tops $103,000, and the BET applies above $281,000 in gross receipts or enterprise value tax base. Below both lines, no return is due, though the DRA can still ask you to confirm you’re under.
Does a New Hampshire LLC need a Meals and Rentals tax license?
Only if it sells prepared meals, rents rooms or short-term lodging, or rents motor vehicles. Restaurants, cafés, hotels, and Airbnb-style hosts all need the Meals and Rentals license before collecting the tax. A typical service, consulting, or e-commerce LLC never touches it.
Is the EIN really free for a New Hampshire LLC?
Yes, completely free, with no exceptions. The IRS never charges for an EIN, online or by mail. Any website billing you $150 to $300 for the number itself is reselling a free federal service, and the same application takes you only one sitting to do yourself.
Can a foreign owner get an EIN for a New Hampshire LLC without an SSN?
Yes. A non-U.S. responsible party can’t use the online tool, so the path is Form SS-4 by fax or mail, or a call to 267-941-1099, the IRS line for international applicants with no U.S. presence. Fax usually returns the number in about four business days; mail takes roughly four weeks.
Do single-member New Hampshire LLCs need an EIN?
Not as a federal requirement, as long as there are no employees; a solo LLC is a disregarded entity and can run on the owner’s SSN. In practice almost every owner gets one, because New Hampshire banks expect it to open a business account and it lets you hire cleanly the day your first employee starts.
