A Taxpayer Identification Number (TIN) is an identifying number used for tax purposes in the United States. It is also known as a Tax Identification Number or Federal Taxpayer Identification Number. A TIN may be assigned by the Social Security Administration or by the Internal Revenue Service (IRS). Section 6109(a) of the Internal Revenue Code provides (in part) that "When required by regulations prescribed by the Secretary (the Treasury or his delegate ) (. . . ) Any person required under the authority of this title (under the Internal Revenue Code ) to make a return, statement, or other document shall include in such return, statement or other document such identifying number as may be prescribed for securing proper identification of such person."〔See subsection (a), paragraph (1) of .〕 Internal Revenue Code section 6109(d) provides: “The social security account number issued to an individual for purposes of section 205(c)(2)(A) of the Social Security Act (as ) shall, except as shall otherwise be specified under regulations of the Secretary (the Treasury or his delegate ), be used as the identifying number for such individual for purposes of this title (Internal Revenue Code, title 26 of the United States Code ).”〔See subsection (d) of .〕 A TIN may be: * a Social Security number (SSN) * an Individual Taxpayer Identification Number (ITIN) * an Employer Identification Number (EIN), also known as a FEIN (Federal Employer Identification Number) * an Adoption Taxpayer Identification Number, used as a temporary number for a child for whom the adopting parents cannot obtain an SSN〔(IRS website: Adoption Taxpayer Identification Number )〕 * a Preparer Tax Identification Number, used by paid preparers of U.S. tax returns〔(IRS website: New Requirements for Tax Preparers )〕 SSNs are used by individuals who have the right to work in the United States. ITINs are used by aliens who may or may not have the right to work in the US, such as aliens on temporary visas and non-resident aliens with US income. Often people need the identification number because they have been advised by a bank that no account will be opened without a number, even if the account is being opened by a non-profit organization. EINs are used by employers, sole proprietors, corporations, partnerships, non-profit associations, trusts, estates of decedents, government agencies, certain individuals, and other business entities. == Notes == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Taxpayer Identification Number」の詳細全文を読む スポンサード リンク
