An Employer Identification Number (EIN) is a nine-digit number the IRS uses to identity taxpayers who are required to file various business tax returns. EINs are used by employers, corporations, partnerships, and sole proprietors, among other business entities. You can apply for an EIN online through the IRS website
If your business has employees, that makes you an employer, and that means you must deposit and report employment taxes. The primary taxes you’re responsible for include:
If you are self-employed earning $400 or more annually, you need to pay the self-employment tax, which consists of Social Security and Medicare taxes. For most wage earners, these taxes are figured by their employers, but as your own employer, you need to calculate the self-employment tax yourself using Schedule SE on Form 1040.
In addition to business taxes required by the federal government, you may have state and local tax obligations as well. The most common small business state tax requirements are income taxes and unemployment taxes. Nearly every state has a business or corporate income tax and all states require payment of state workers’ compensation insurance and unemployment insurance taxes.
Generally, you should collect, report and pay sales tax on most goods and some services that are delivered to a customer in a state where your business has a physical presence. But sales tax rates and regulations vary from state to state and even city to city or county to county. To find the sales and use tax rates for your area, go online and search your state’s department of revenue or taxation.
