Obtaining a Taxpayer Identification Number (TIN) is a crucial step for many individuals and businesses interacting with the U.S. tax system. This comprehensive guide will walk you through the process, clarifying the different types of TINs and how to apply for the one you need.
Understanding Different Types of TINs
Before diving into the application process, it's important to understand the various types of TINs available. The most common are:
-
Social Security Number (SSN): This is the most widely used TIN for U.S. citizens and permanent residents. It's primarily used for individual income tax purposes. You do not need to apply for an SSN; it is issued by the Social Security Administration (SSA).
-
Individual Taxpayer Identification Number (ITIN): Foreign nationals and resident aliens who do not have and are not eligible for an SSN but need one for tax purposes are issued an ITIN. This number is used for filing federal tax returns and claiming any related tax benefits. Learn how to apply for an ITIN below.
-
Employer Identification Number (EIN): Also known as a Federal Tax Identification Number (FTIN), an EIN is used by businesses, corporations, partnerships, trusts, and other entities for tax reporting purposes. Learn how to apply for an EIN below.
