State of Maine

  1. Maine Business Registration (Secretary of State)

    Bookkeeping and accounting businesses operating in Maine register with the Maine Secretary of State's Bureau of Corporations, Elections and Commissions if structured as an LLC, corporation or partnership. An LLC is formed by filing a Certificate of Formation (form MLLC-6). Sole proprietors do not register with the State: a sole proprietor or partnership using a trade name files an assumed-name certificate with the city or town clerk where the business is located, under 31 MRSA section 2. An LLC is commonly chosen for the personal liability protection it provides.

    $175 Certificate of Formation filing fee for an LLC (form MLLC-6); expedited service costs $50 extra for next-business-day or $100 for same-day filing. A sole proprietor pays no state filing fee - the trade name certificate goes to the city or town clerk instead.The Bureau of Corporations, Elections and Commissions currently reports corporate filing processing time of 40-55 business days; expedited filing is available for the added fee

  2. Maine Sales Tax Registration (Maine Revenue Services)

    Maine taxes sales of tangible personal property and a short statutory list of services; bookkeeping and accounting services are not on that list, so the service itself is not taxable. Maine's Service Provider Tax, which covered a separate set of services, was repealed effective 1 January 2026. You still register with Maine Revenue Services for a sales tax account if you sell taxable goods at retail, and you owe use tax at 5.5 percent on supplies and equipment bought untaxed for your own use.
