What is a Tin Number?

A Taxpayer Identification Number (TIN) is a nine-digit number used in the United States to identify a person or legal entity that is required to pay taxes. It is also known as a Tax ID Number or Federal Taxpayer Identification Number. The Internal Revenue Service (IRS) assigns the TIN number. It is used to identify income from taxable sources, track taxes paid, and to issue refunds when needed.

Who Needs a Tin Number?

Most entities, organizations, and individuals must have a TIN number for the purpose of filing taxes with the IRS. Sole proprietors must also have a TIN number, and it may be used as a substitute for an Employer Identification Number (EIN). If you already have a Social Security Number (SSN) you only need to provide it for tax filing purposes. Additionally, you may use your SSN if your business operates as a sole proprietor who is not subject to corporate income taxes. However, those who are required to pay other taxes such as self-employment tax, must obtain an EIN or a TIN, depending on the tax form filing requirements.

How to Obtain a Tin Number

To get a TIN number you must complete the appropriate IRS forms. The forms should be filed with the appropriate IRS office according to your type of organization, or depending on the type of document you need. The forms that must be completed vary depending on the entity. Generally, if you are a citizen or a resident alien of the United States, you need to have a Social Security Number to obtain a TIN.

Taxpayers must also provide other information such as names, address, and date of birth when applying for a TIN. Individual taxpayers should apply for a TIN online. This application is usually done during the tax filing process. Businesses are required to use a paper application in order to obtain a TIN number.

Individuals and businesses must provide other documents when applying for a TIN. These documents vary, but generally include a birth certificate or similar identification, passports, and Social Security cards. Additionally, corporations and partnerships should provide articles of incorporation when filing for a TIN.

In conclusion, a TIN number is a nine-digit number that is used for tax filing purposes. It is assigned by the IRS and is required for filing taxes. Most organizations and individuals are required to obtain a TIN number when filing taxes. The forms that must be completed and the documents depends on the type of entity and the type of document required.
