What is an EIN?
An EIN, or Employer Identification Number, is a unique nine-digit number assigned by the IRS to identify your business entity. It's essentially a Social Security number for your agency, allowing you to hire employees, open business bank accounts, and file taxes. Our resource on [starting a business in Maine](https://www.lovie.co/formation/resources/llc-formation/agency-maine) breaks this down further.
How to Apply for an EIN
Determine Your Eligibility: Ensure your agency business is eligible for an EIN. Generally, any entity formed as a corporation or partnership, or any entity that hires employees, needs an EIN. If you're a sole proprietor without employees, you can use your Social Security number, but an EIN still offers benefits.
Choose Your Business Structure: Decide on your agency's legal structure (LLC, S-corp, etc.). This will impact how you apply for the EIN and your ongoing tax obligations. In Maine, LLCs are a popular choice due to their flexibility and liability protection.
Gather Required Information: Collect all necessary information, including your agency's legal name, address, responsible party (owner, partner, or officer), and the reason for applying for the EIN. You'll also need to provide the date your agency was formed in Maine.
Complete Form SS-4: Fill out IRS Form SS-4, Application for Employer Identification Number. This form can be completed online or downloaded and mailed in. The online application is generally the fastest method.
Submit Your Application: Submit the completed Form SS-4 to the IRS. If applying online, you'll receive your EIN immediately. If mailing the form, it can take several weeks to receive your EIN.
Receive and Store Your EIN: Once your application is processed, you'll receive your EIN from the IRS. Store this number securely, as you'll need it for various business activities, including banking, taxes, and licensing.
