American taxpayer identification number coding rules

I. Introduction of taxpayer identification number

American taxpayer identification number includes social security number (SSN) used by individuals and employer identification number (EIN) used by individuals or entities. In addition, an individual taxpayer identification number (ITIN) will be issued to individuals who should have an American taxpayer identification number but have not obtained or are not qualified to obtain a social insurance number.

taxpayers must indicate their taxpayer identification number (i.e. SSN, EIN or ITIN) on all tax returns and other documents submitted to the IRS. When others need to use the taxpayer's taxpayer identification number on the declaration form or other documents submitted to the domestic revenue bureau, the taxpayer must provide the taxpayer identification number to others.

the social security number is issued by the Social Security Administration of the United States. for more information, see www.ssa.gov.

The employer identification number is issued by the Internal Revenue Service to self-employed, partnerships, companies (including limited liability companies) and other tax entities for filling out and submitting tax returns. You can apply for the employer's identity number by the following methods: 1) submit the SS-4 form application online; 2) Mail or fax SS-4 form. Applicants outside the United States can call (267)941-199 (toll phone) for consultation. For more information, please refer to the publication No.1635 of the Internal Revenue Service, "Know Your Employer Identification Number".

The individual taxpayer identification number is issued by the Internal Revenue Service to individuals who should have the taxpayer identification number, but have not obtained the social security number from the General Administration of Social Security or are not eligible for it. The issuance of individual taxpayer identification numbers has nothing to do with immigration status, because both American residents and non-resident foreigners may need to declare tax. Unless in special circumstances, an individual must fill in a valid federal income tax return to obtain an individual taxpayer identification number. Individuals can apply for individual taxpayer identification number by filling in the W-7 form, that is, the application form for individual taxpayer identification number.
