First, Determine if You Need an EIN
Once your business has been legally registered, you can apply for an EIN, and the IRS will use your company’s EIN to track your business income taxes, as well as to receive the taxes that you are required to pay.
If you are not a U.S. citizen and you’re located outside of the United States but you’re doing business in the country, such as running an e-commerce storefront or selling on Amazon, you need to go through the appropriate steps to get your EIN and report your earnings.
If you don’t have an ITIN (Individual Taxpayer Identification Number) or SSN (Social Security Number), your EIN will be used instead. Plus, if you are importing goods into the U.S., you will need to show an EIN if you don’t already have an ITIN or SSN. This number will also help you avoid the complex forms from U.S. Customs and Border Protection.
