Get a federal tax ID number
Your Employer Identification Number (EIN) is your federal tax ID. You need it to pay federal taxes, hire employees,open a bank account,and apply for business licenses and permits.
It's free to apply for an EIN, and you should do it right after you register your business.
Your business needs a federal tax ID number if it does any of the following:
- Pays employees
- Operates as a corporation of partnership
- Files tax returns for employment, excise, or alcohol, tobacco and firearms
- Withholds taxes on income, other than wages, paid to a non-resident alien
- Uses a Keogh Plan (a tax-deferred pension plan)
- Works with certain types of organizations
Apply for an EIN with the IRS assistance tool. It will guide you through questions and ask for your name, social security number, address, and your "Doing Business As" (DBA) name. Your nine-digit federal tax ID becomes available immediately upon verification.
Change or replace your EIN
If you already have an EIN, you might have to change or replace it with a new one if certain changes have occurred with your business.
Types of business changes that might require you to change or replace your EIN are:
- Name change
- Address change
- Changes in ownership
- Changes in management
- Change in tax status
Your requirements will depend on your business structure and the kind of change that occurred. Check with the IRS to determine exactly whether you need to change or replace your EIN.
