Every Line of the MLLC-6
LLC name
With a valid designator, distinguishable from the record — verified in Step 1. If you reserved the name, your reservation covers this filing.
Filing date option
Effective on filing by default, or specify a later effective date if you want a clean-year start.
Designations (if applicable)
Low-profit LLC (L3C) or professional LLC checkboxes, if your entity is one.
Registered agent
Commercial agent by CRA number, or noncommercial agent by name and physical Maine street address — Step 2's decision.
Authorized person's signature
Signed and dated by an authorized person — unsigned forms are the classic bounce.
The cover essentials
A contact name plus phone or email (the instructions warn omissions can get erroneous filings returned), your $175 payment, and the expedite cover sheet if you're buying speed.

After Approval: Your Immediate Next Moves
- File your stamped certificate somewhere safe the day it arrives back — banks want it, and note your formation date.
- Create your operating agreement — the document that overrides Title 31's defaults.
- Get your free EIN at IRS.gov, then register with Maine Revenue Services.
- Calendar June 1 — your first $85 annual report is due January 1–June 1 of the year after your formation year, and Maine will not mail you a form.
Ahmad Adil's Take: treat the MLLC-6 like a flight with no standby: you get one boarding, so check everything twice at the gate. My ritual for Maine clients — photograph every page and the check before sealing the envelope, send it with tracking, and put the expected-response date on the calendar. If nothing arrives two weeks past that date, call Augusta with your tracking number. Paper systems reward people who keep receipts; be one of them.
