What is a Federal Employer Identification Number?
A Federal Employer Identification Number (FEIN or EIN) is a nine-digit ID the IRS gives to businesses. It works like a Social Security Number but for companies. The EIN is used when filing taxes, running payroll, and reporting wages. Without it, businesses can’t properly file returns, pay employees, or open a business bank account.
How Federal Employer Identification Number (EIN) works in payroll?
Every employer with staff must have an EIN. It appears on tax forms like W-2 and Form 941. The number is permanent, and even if the owner changes, the business keeps the same EIN. If you change the structure—like moving from sole proprietor to corporation—you usually need to apply for a new one.
In payroll, the EIN is tied to reports such as the payroll register and it connects with year-end details like YTD tax. When you pay contractors, the EIN is also used on forms like the 1099-MISC or the 1099-NEC.
Why Federal Employer Identification Number (EIN) matters for pay stubs
On an employee pay stub, the employer’s details usually include the EIN. This helps both the employee and the IRS track wages correctly. If you run payroll in more than one state, as in multi-state payroll, the EIN stays consistent across all locations.
