An Employer Identification Number, or EIN for short, is basically a social security number for your business. Like with social security numbers, the IRS uses EINs to track what businesses need to certain types of tax. However, not all businesses are technically required to have an EIN as sole proprietorships can be identified by the owner’s SSN instead. That doesn’t mean, though, that you should avoid filing for one, as there are three main reasons why obtaining an EIN is important for a small business.
It allows the business to hire employees.
If you run a sole-proprietorship and you are the only employee that works for the business, all of the profits and losses are going to be reported as part of your personal income. You then pay whatever state and federal taxes you need to, just like you would if you received an income from anywhere else. However, when you hire an employee, you are responsible for withholding any necessary taxes from that employee’s income. The IRS then cannot simply use your SSN to keep track of what they are owed as there are now two different employees, and that’s where the employer identification number comes in. EINs let the IRS and other tax-collecting bodies know what businesses need to be sending in the usual payroll taxes.
