What Is an SSN?

We briefly explained SSN also known as Social Security Number for you to understand. Let’s delve into this a little further.

A Social Security Number is a number assigned to United States citizens and residents so that the government can keep track of their income and calculate their payments accordingly.

SSNs were introduced as a part of The New Deal in 1936 to aid citizens receive retirement and disability benefits. Originally intended to keep a record of how much an individual earned and to collect benefits, SSNs now also serve to identify people for taxation, calculate credit scores, and so on.

When you need to borrow money, open a bank account, receive assistance from the government, or purchase goods over a certain price, you are requested to provide them with your SSN.

What Is an EIN?

Now, let’s talk about another important identification number: EIN. That is also known as Employer Identification Number.

An Employer Identification Number (EIN) is a nine-digit number identified as a Tax I.D. or Federal Tax Identification Number (FTIN) issued by the Internal Revenue Service (IRS). It is socially roughly equivalent to the social security number. Known as the Web EDI Tax folder (WET) it is employed by the Internal Revenue Service (IRS) to monitor business tax returns and payments.

Thus, if you have a business venture or you are planning to hire employees necessary for your business, then you need to have an EIN for legitimacy purposes with the IRS. It will help in organizing things for tax purposes and also make the government to monitor your business accounts in order to facilitate taxation purposes.

What Is an ITIN?

The next topic in our discussion is an ITIN – an Individual Taxpayer Identification Number.

An Individual Tax Identification Number (ITIN) is a number issued by the United State Internal Revenue Service (IRS) which helps solely in the processing of tax returns.

It primarily provides the purposes of allowing those not eligible for an SSN to meet the requirements of the U. S. tax laws. Among the grantees are non-resident aliens, certain resident aliens, and dependants or spouses of US citizens or resident aliens who are required to file or be able to file for a US tax return.

ITIN does not confer the blessed individual with a work permit nor enables him or her to receive social security. This is simply because it is for the IRS to monitor that even those who might not be legally registered in the country should ensure that they comply with the U. S tax code through filing their taxes.
