You need two separate Tax Identification Numbers in the state of Maine:
  • State Income Withholding Tax - Withholding Account Number
  • State Unemployment Insurance Tax - Employer Account Number
You can register for both Tax Identification Numbers online at the Maine Employer Registration Internet System website. Contact the agency directly at 1-207-626-8475 for registration assistance or to check if a tax identification number is already assigned for your business.

Normally, you'll receive your Withholding Account Number in 5-7 days after registering. The Tax ID typically ends in 00.

You should receive your Employer Account Number in about 5-7 days.
You only need to know one tax rate assigned for the current year:
  • Maine Experience Rate
Your contribution rate will be assigned when you register and will be updated on an annual basis from the Department of Labor. Contact the agency directly at 1-207-627-5120 to verify your current rate.
Send any tax identification number or tax rate updates to your Account Executive or email [email protected].
