Maine charges $175 to form an LLC; New Mexico charges $50. Day-one sticker price is only part of the story, since most of the real cost comes from the annual obligations that stack up each year you keep the LLC open.

Over a rolling three-year window, New Mexico runs about $380 less in total state fees than Maine. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.

On speed, New Mexico typically clears standard online filings faster than Maine. Both states offer expedited tiers at an additional cost for filers on tight timelines.

For most small operators the choice is not really between these two states at all. It is between forming where the business actually operates and trying to route through a non-resident filing. The data below shows what each option actually costs.

Formation process, side by side

What actually happens from the moment you start filing to the moment you're in good standing. Use this as a checklist.

Maine

  1. Check business-name availability on the Maine entity search.
  2. Appoint a registered agent with a physical Maine street address.
  3. File Certificate of Formation (Form MLLC-6) for $175.
  4. Wait for approval. Paper-only processing. Paid expedite from $50.
  5. Adopt a written operating agreement (statutorily required in Maine).
  6. Apply for a federal EIN (free from the IRS).
  7. Open a business bank account to separate personal and business finances.
  8. File your first annual report and pay $85 when it comes due.

New Mexico

  1. Check business-name availability on the New Mexico entity search.
  2. Appoint a registered agent with a physical New Mexico street address.
  3. File Articles of Organization for a Domestic Limited Liability Company for $50.
  4. Wait for approval. Online typically 3 business days. No paid expedite offered.
  5. Adopt an operating agreement (recommended, not required by New Mexico statute).
  6. Apply for a federal EIN (free from the IRS).
  7. Open a business bank account to separate personal and business finances.
  8. No annual state filing required in New Mexico.

Before you pick either state

A few things that apply no matter which state you choose. These trip up enough first-time filers that they're worth stating explicitly.

Registered agent is non-negotiable. Both Maine and New Mexico (and every other US state) require every LLC to designate a registered agent with a physical street address in the state of formation. You can serve as your own agent if you live in the state; otherwise a commercial agent runs $50 to $125 per year. Using your own home address makes it part of the public record.

Forming elsewhere does not escape your home state's tax. If you live and operate a business from your home state, forming the LLC in Maine or New Mexico does not avoid your home state's income tax. The moment you transact business at home, your home state requires a foreign LLC registration, and state tax liability follows your residence regardless of where the entity sits on paper.

EIN applications are free. The IRS issues Employer Identification Numbers directly at no cost. Any service charging you to "get your EIN" is reselling a free form submission. Single-member LLCs with no employees technically don't need one for federal tax, but nearly every bank requires an EIN to open a business account.

Operating agreement matters more than the state you pick. A well-drafted operating agreement governs member ownership, management, profit splits, buy-sell terms, and dissolution. Without one, your LLC runs on the state's default rules, which are rarely what you want. California, Maine, Missouri, and New York require a written one by statute; every other state treats it as strongly recommended.

Frequently Asked Questions

  • Is it cheaper to form an LLC in Maine or New Mexico?

    New Mexico is cheaper at formation ($50) than Maine ($175). Ongoing costs are also different: $100 vs $185 per year. Total over three years: $350 vs $730.

  • Can I form an LLC in Maine if I live in New Mexico?

    Yes, but your New Mexico business will almost certainly need to register as a foreign LLC in New Mexico too, which means paying New Mexico's foreign registration fee and any ongoing New Mexico obligations on top of the Maine ones. The "form elsewhere to save" math usually doesn't work for operating businesses; it only works when you have no physical operations tied to any specific state.

  • How long does it take to form an LLC in Maine vs New Mexico?

    Maine online turnaround varies; New Mexico online: 3 business days. Maine offers paid expedite from $50. New Mexico does not offer paid expedite.

  • Which state has lower taxes for an LLC, Maine or New Mexico?

    Maine: state income tax applies to member-level pass-through income, no entity-level franchise or LLC tax. New Mexico: state income tax applies to member-level pass-through income, no entity-level franchise or LLC tax.

  • Do both states require a registered agent?

    Yes. Every US state (and DC) requires every LLC to maintain a registered agent with a physical street address in the state. Maine and New Mexico both have this requirement. You can serve as your own agent if you live in the state; most out-of-state filers use a commercial agent for $50 to $125 per year.

  • Do I need a written operating agreement in Maine or New Mexico?

    Maine requires LLCs to adopt a written operating agreement by statute. New Mexico treats it as strongly recommended rather than required. In practice, any LLC with more than one member, or any LLC planning to preserve its liability shield, should have a written agreement regardless of which state it's formed in.

  • Which state should I pick if I run an online business from home?

    Form in the state you actually live in. Your home state's Department of Revenue treats your residence as nexus regardless of where the LLC is filed, which means you owe state income tax there anyway. Forming in Maine or New Mexico to escape your home state's tax doesn't work; it adds paperwork. The non-resident filings make sense when you genuinely operate nowhere in particular: international founders, purely passive holding entities, or real-estate LLCs owning property in other states.

  • Annual report: www.sos.nm.gov/business-services/ · verified April 21, 2026
    The New Mexico LLC Act imposes no annual or biennial report requirement, and the Secretary of State's Business Services fee list contains no annual report line item for LLCs. This absence of annual filing is a long-standing feature of the New Mexico LLC Act and one of the main reasons anonymous-LLC strategies favor New Mexico.
  • Franchise tax: www.tax.newmexico.gov/businesses/corporate-income-franchise-tax-overvi… · verified April 21, 2026
    New Mexico's $50 Corporate Franchise Tax applies to entities taxed as corporations for federal purposes, including LLCs that have elected C-corp or S-corp treatment. LLCs that default to pass-through partnership or disregarded-entity treatment do not owe the $50 franchise tax and file no corporate-level franchise return in New Mexico. For default-tax-classification LLCs (the overwhelming majority), no state-level franchise tax applies.
  • Corporate income tax rate: www.tax.newmexico.gov/all-nm-taxes/current-historic-tax-rates-overview… · verified April 21, 2026
    Effective for tax year 2025 and later, New Mexico replaced its two-bracket corporate income tax (4.8% on the first $500,000 and 5.9% above) with a single flat rate of 5.9% on all corporate taxable income. Confirmed by the Tax Foundation 2026 State Tax Competitiveness Index (Oct 2025) and the NM Taxation and Revenue Department. LLCs pay this rate only if they elect C-corp federal taxation; default pass-through LLCs do not.
  • Sales tax rate: www.tax.newmexico.gov/businesses/gross-receipts-overview/ · verified April 21, 2026
    New Mexico's Gross Receipts Tax (GRT) functions as the state's sales tax. Effective July 1, 2025 the statewide GRT rate is 4.875%. The GRT is imposed on the seller's receipts rather than the buyer's purchase, so it applies more broadly than a typical sales tax (including to many services and business-to-business transactions). Counties and municipalities add layered local GRT rates, resulting in combined rates that typically range from 6.5% to 9%. Only the statewide 4.875% rate is recorded here.
