Best Maine LLC Formation Service in 2026
Maine is unusual: the state does not offer online LLC filing. Every Certificate of Formation has to be mailed in, $175 by check or money order, and the state takes 10–15 business days plus mail transit on top. For a non-US founder trying to launch in a hurry, the service you pick is the difference between "running in 4 weeks" and "still waiting in 4 months."
We compared the 6 major providers on what actually matters when the state itself is the bottleneck.
Quick verdict
| Service | Best for | Filing fee (Maine) | Service fee | Reg. Agent | EIN included | Non-US friendly |

| Doola | Non-US founders, one-person company | $175 | from $297 (Starter) | ✅ 1 yr | ✅ (incl. SS-4 paper filing) | ⭐⭐⭐⭐⭐ |
| Northwest | US residents wanting privacy | $175 | $39 + state | ✅ 1 yr | ❌ (+$50) | ⭐⭐⭐ |

| LegalZoom | US residents wanting brand | $175 | $0 (Basic) | $249/yr | ❌ (+$79) | ⭐⭐ |
| Bizee (formerly IncFile) | US residents, free starter | $175 | $0 + state | ✅ 1 yr | ❌ (+$70) | ⭐⭐ |
| DIY (Maine SOS by mail) | Founders with US SSN + address | $175 | $0 | ❌ ($125+/yr separately) | DIY (free with SSN) | ⭐ |
Our recommendation for non-US founders: Doola — bundles LLC + EIN (SS-4 paper for non-SSN founders) + Registered Agent + Mercury Bank introduction. They also handle the mail-only filing logistics, which is non-trivial from outside the US.

Maine LLC basics
- Filing fee: $175 (Certificate of Formation, mail-only — no online filing in Maine)
- Annual report: $85 per year, due by June 1 every year
- State income tax: graduated 5.8%–7.15% on Maine-sourced personal income; Maine honors federal pass-through treatment
- Privacy: registered agent's name and address are public; members are not required on the public filing
- Processing: 10–15 business days for mail filings, plus delivery time both ways
- No general state business license at the state level
The mail-only filing is genuinely the biggest practical issue. From outside the US it means an international money order, courier service for the form, and another 10–15 business days for the state. Doola and the other paid services handle the US-side mail logistics for you.
Service-by-service breakdown
1. Doola — best for non-US founders forming a Maine LLC
- Pricing: Starter $297/yr, Total Compliance $799/yr
- Includes: LLC filing (mail logistics handled) + EIN (SS-4 paper for non-SSN founders) + Registered Agent (1 yr) + US business address + Mercury Bank introduction
- Turnaround: 4–6 weeks for non-US founders (Maine mail queue + EIN bottleneck), 3–4 weeks for US founders
- Why we use it: Two compounding bottlenecks here — Maine's mail-only filing and the SS-4 paper EIN. Doola is the only major service that handles both end to end.
- Caveat: Higher renewal cost than Northwest. If you have a US SSN, Northwest is cheaper year 2 onward.

Step-by-step Maine LLC formation
- Choose a name — must include "LLC", "L.L.C.", or "Limited Liability Company". Check at the Maine corporate name search.
- Designate a registered agent — must have a physical Maine street address (no PO Boxes). Commercial RAs are common since Maine has many out-of-state founders.
- File Certificate of Formation by mail — $175 check or money order to the Maine Secretary of State. No online option. Processing is 10–15 business days plus mail time.
- Get an EIN from the IRS — free online with SSN. Non-US founders file SS-4 by fax/mail, 4–8 weeks. Doola does this for you.
- Open a US business bank account — Mercury Bank, 3-hour approval if your LLC + EIN are clean.
- File the Annual Report — $85, due by June 1 every year. Late fees start the day after.
Maine's quirk: Filing must be on paper, by mail. This is the only state in our coverage that has no online formation portal as of 2026. Budget an extra 2–3 weeks vs a comparable online state like Indiana or Iowa.
FAQ
Why can't I file a Maine LLC online?
The Maine Secretary of State has not modernized LLC formation to support online filing. Every Certificate of Formation must be mailed in with a paper check or money order. Annual reports, however, can be filed online.
Can a non-US resident form a Maine LLC?
Yes. No citizenship or residency requirement. You need a Maine-based registered agent (any service above) and an EIN, which Doola files by SS-4 paper if you don't have an SSN. The mail-only filing makes a paid service much more valuable here than in online-friendly states.
What's the cheapest way to form a Maine LLC?
DIY by mail: $175 filing + $85/yr annual report + ~$125/yr registered agent. Total year-1 cost ~$385. But the mail logistics make this painful from outside the US.
Is Maine better than Wyoming for non-US founders?
For ease and cost: no, Wyoming is online, cheaper, and faster. Form in Maine only if you have actual Maine business activity (tourism, real estate, lobster anything). See our best state for LLC comparison.
