Get An EIN (Employer Identification Number) For Your C-Corp


To get an EIN in the US is not a hard nut to crack. All you need to do is to be crystal clear about all the fundamental rules and regulations. Entrepreneurs obtain EIN for running businesses in the US. Particularly, if you’re planning to start a small business in the US, then you must need an EIN that’s also called Federal Tax ID Number (FTIN). The IRS (Internal Revenue System) identifies it for your corporation in the US for federal taxes. Simply, when you’re ready to file your income and payroll taxes, you should get an EIN. In other cases like an LLC or sole proprietorship, you must use SSN (Social Security Number). 

When You Need an EIN? 

In the US, every business needs an EIN. This simple number needs to be identified quickly for different tax purposes. Once you register a legal business, you can apply for it and the IRS will track your income taxes through it. However, if you’re not a US citizen and located outside of the US, you must be aware of the appropriate procedure for receiving an EIN. Therefore, it’s important first to determine why you need an EIN in the first place. 

If you want to run an online eCommerce set-up in the US or sell on Amazon, you have to report your earnings through EIN. Your EIN can be used instead of an SSN (Social Security Number), or ITIN (Individual Taxpayer Identification Number). Plus, you need to show an EIN when you’re importing goods into the US. You can simply avoid complex documentation simply by having this unique number from US Customs and Border Protection.
