Starting a business involves paperwork—and one of the first steps is obtaining an EIN. If you’re wondering how to get EIN number for business, this guide walks you through the process clearly and quickly.
An Employer Identification Number (EIN) is a 9-digit number issued by the IRS to identify your business for federal tax purposes. It functions like a Social Security number but for your company.
Who Needs an EIN Number?
You need an EIN if your business:
- Has employees
- Operates as a corporation or partnership
- Files employment or excise taxes
- Withholds taxes on income (other than wages)
