Step 1: Determine Your Eligibility:

Before applying for an EIN, it’s important to verify that you meet the eligibility criteria. Generally, if you have employees, operate as a corporation or partnership, or withhold taxes on income (other than wages) paid to a non-resident alien, you are required to have an EIN. Even if your business does not meet these criteria, obtaining an EIN can still be beneficial, as it separates your personal and business finances and may be necessary when opening a business bank account or applying for certain permits or licenses.
