After your EIN in Maine
| Account | Agency | Number you get | Register |
|---|---|---|---|
| State income tax withholding | Maine Revenue Services | Withholding account number, 8 digits | Maine Tax Portal |
| Unemployment insurance | Maine Department of Labor | Employer Account Number (EAN) | ReEmployME |
| Sales tax | Maine Revenue Services | Sales tax registration | Maine Tax Portal |
Maine Revenue Services' tax registration does not cover unemployment or paid leave. Register for an unemployment compensation tax account with the Maine Department of Labor on ReEmployME, and register separately with Maine Paid Family and Medical Leave, which every employer with Maine employees must do.
Although the Department of Labor runs the unemployment account, Maine Revenue Services processes both quarterly employer returns: Form 941ME for income tax withholding and Form ME UC-1 for unemployment contributions.
Also on the Maine list
- Register with Maine Revenue Services on the Maine Tax Portal through the Register a New Business link for the accounts the business needs, such as sales and use tax, service provider tax or income tax withholding. Maine Revenue Services requires an EIN from any registrant other than a sole proprietor, and each account it opens gets its own eight-digit Maine account ID.
- File the annual report with the Division of Corporations between January 1 and June 1 every year, starting the year after the LLC is formed. The report is filed by charter number, online or on a preprinted form.

What is different about Maine
- Maine's charter number ends in letters that show the entity type, and a domestic Maine LLC's ends in DC. The corporate name search and the annual report are keyed to that charter number; the EIN comes into play at Maine Revenue Services, which requires it to open the LLC's tax accounts.
- Every Maine LLC's annual report is due June 1, whatever month the company was formed. A report received after June 1 draws a late filing penalty, and the Secretary of State administratively dissolves an LLC that does not pay that penalty.
- Maine Revenue Services issues the Resale Certificate itself, and only to registered retailers that qualify, separately from the Retailer Certificate that shows the sales tax registration number. A Maine retailer without one pays sales tax to its vendors on goods bought for resale and takes a credit for that tax on its next sales tax return.
Before you apply
The SS-4 must match the Maine Secretary of State, Division of Corporations, UCC and Commissions filing; its charter number is a state index, not a tax ID.
Maine EIN questions
How do I get an EIN number in Maine?
File IRS Form SS-4 after the Maine Secretary of State, Division of Corporations, UCC and Commissions approves any formation filing; there is no Maine EIN application. Then register with the Maine Revenue Services (Maine Tax Portal) for withholding and the sales tax registration and the Maine Department of Labor (ReEmployME) for unemployment insurance.
Is there a Maine EIN or state tax ID number?
No; only the IRS issues EINs (also called the FEIN or federal tax ID). Maine's own numbers are the charter number from the Maine Secretary of State, Division of Corporations, UCC and Commissions, the withholding account number from the Maine Revenue Services, the Employer Account Number (EAN) from the Maine Department of Labor, and the sales tax registration from the Maine Revenue Services.
Is the Maine withholding account number the same as my EIN?
No. The Maine Revenue Services assigns it when you register as an employer in Maine Tax Portal, and it is 8 digits. It goes in W-2 box 15; the EIN goes in box b.
Where do I register for Maine unemployment insurance?
With the Maine Department of Labor, online through ReEmployME. It assigns an Employer Account Number (EAN), a separate number from the EIN.
Do I need a Maine sales tax registration?
Only if you sell what Maine taxes. The Maine Revenue Services issues it through Maine Tax Portal, and your returns are filed under its number, not the EIN.
