FAQ about Employer Identification Number
EIN registration is the process of obtaining an Employer Identification Number from the Internal Revenue Service, which serves as a federal tax identification number for businesses operating in the United States. Businesses need EIN registration if they have employees, operate as a corporation or partnership, file employment or excise tax returns, withhold taxes on income paid to non-resident aliens, or have a Keogh retirement plan. Additionally, many banks require an EIN to open business bank accounts, and marketplaces like Amazon, Stripe, and PayPal typically require an EIN for merchant accounts. While sole proprietors without employees can sometimes use their Social Security Number instead, obtaining an EIN registration is recommended for liability protection and professional credibility. The number is issued free by the IRS and remains with the business permanently unless the entity dissolves.
