Our EIN service will help you obtain a Federal Tax ID Number or Employer Identification Number (EIN), for your business. This is the equivalent to a Social Security Number (or ITIN) for a business.

The IRS uses an EIN to identify a business, and it must be included in all your business tax filings. You will need an EIN to open a US bank account in the name of a separate legal entity.

As an e-commerce seller, you may need an EIN number when creating your seller account in the United States whether you are selling on Amazon, Walmart, eBay, Etsy…

US Customs and Border Protection (CBP) requires an identifying number as well. In general, the more info that can be provided to CBP at the time of importing your products to the U.S. the smoother the process goes, and the faster your goods will be in a third-party warehouse.

You will need an EIN when you register for sales tax permits in the states you have nexus. Even if you are selling on a marketplace facilitator, where they collect and remit in 41-42 states, there are a few states you may be required to register.

What does it require to update the SS4 application submitted to the IRS?

Your options include filing form 8332, if appropriate, to make another election with the IRS that will match the expected US tax return to be filed. Even if there is a tax treaty with your country, you will want to make sure you file the correct U.S. return, to take advantage of treaty benefits.

There is no official process for changing mistakes made on your SS4 application, other than to write the IRS a letter. This should be sent certified mail, and it may take months to receive an answer, which may or may not be an approval to what you want to change. The other approach is to work with your CPA firm to file the corrected US tax return, wait for the IRS to send a letter that the wrong return was filed, and then reach out to the IRS to let them know there was a mistake on the SS4 application and see, at that point, if they will fix it.

In the end, it Is better to make sure your EIN is filled out correctly. Our team has a detailed spreadsheet of different situations and how to fill out the SS4 application. This has been reviewed by tax professionals (more than one) to make sure everything matches up. Sales Tax System’s internal SS4 spreadsheet is used to check your SS4 application before we call the IRS.
