The reason why some may find the prospect of finding out their taxpayer identification number daunting could be because there are three main types of abbreviations which refer to the taxpayer identification number, and you may not know which one you need. These three abbreviations are: TIN, ITIN, and EIN. The TIN stands for taxpayer identification number which is an umbrella term for what we are talking about. If you are US citizen who pays tax, you will have been issued a TIN which is identical to your social security number (SSN). What is your SSN? You can request a replacement SSN card at the SSA’s website to find out your social security number.
However, if you are an employer, you may also be wondering what your EIN is. You’ll need to file for an Employer Identification Number or EIN. This number is issued to individuals and legal entities, depending on a business’ legal structure. The IRS issues this number to various business structures, including sole proprietors, partnerships, and corporations (including LLCs). You can get more information on employer identifications numbers in this PDF file from the IRS: IRS Publication 1635, Understanding Your EIN. Note that you will need an EIN in addition to your SSN; one functions as your individual number, the other as your number as an employer.
So far we have seen that your TIN information may just be the same as your SSN, or it may be your SSN and an EIN. However, it may be that you are not eligible for an SSN. What to do then? What is your taxpayer identification number if you do not have a social security number? In this case, you will have to request an ITIN, which stands for Individual Taxpayer Identification Number.It is only issued to those non-resident and resident aliens, their spouses, and dependents who do not have and can’t be issued an SSN. This number can be requested regardless of immigration status.
To sum up, there are a few different types of TIN depending on your status:
- As an individual: Your TIN is the same as your social security number.
- As an entity: Your TIN is most likely the business entity’s Employer Identification Number (EIN). However, an entity with the legal structure of an S-corp corporations, for example, may have the TIN may be that of the owner. The specifics of your TIN as an entity should be reviewed with a legal advisor.
- As an individual without a SSN: Your TIN is issued as an ITIN, a 9 digit number you receive from the IRS.
