What is a Fed ID?
A Fed ID, also known as a Federal Employer Identification Number (FEIN) or Employer Identification Number (EIN), is a unique nine-digit number the IRS assigns to businesses for tax reporting purposes. It acts like a company's Social Security Number (SSN), helping the IRS track tax obligations.
You’ll need a Fed ID if your business has employees, operates as a corporation or partnership, or files certain tax returns. Collaborate with Homebase payroll to manage your business legally and ensure proper payroll handling.
Why businesses need a Fed ID
A Fed ID is required for several key business operations, including:
- Hiring employees – Needed to report wages and payroll taxes to the IRS.
- Filing federal and state taxes – Used when submitting business tax returns.
- Opening a business bank account – Most banks require an EIN.
- Applying for business licenses and permits – Many local and state agencies require a Fed ID.
- Issuing tax documents – Employers must include their EIN on W-2s and 1099s.
Businesses may face compliance issues and tax processing delays without a Fed ID.
How to apply for a Fed ID
Applying for a Fed ID is free and can be done through the IRS in a few ways:
- Online – The fastest and easiest method via the IRS EIN application page.
- By mail or fax – Using Form SS-4, though processing can take a few weeks.
- By phone – Available for international applicants only.
Once assigned, your EIN stays with your business for life unless there is a significant change in ownership or structure.
