What is an ITIN?
An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued to nonresident Aliens (NRA) by the Internal Revenue Service. It is a nine-digit number that always begins with the number 9 and has a range of 70-88 in the fourth and fifth digit. Effective April 12, 2011, the range was extended to include 900-70-0000 through 999-88-9999, 900-90-0000 through 999-92-9999 and 900-94-0000 through 999-99-9999. IRS issues ITIN‚Äôs to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain a Social Security Number (SSN) from the Social Security Administration (SSA).
ITIN‚Äôs are issued regardless of immigration status because both resident and nonresident aliens may have a U.S. filing or reporting requirement under the Internal Revenue Code.
Individuals must have a filing requirement and file a valid federal income tax return to receive an ITIN.
What is an ITIN used for?
ITIN‚Äôs are for federal tax reporting only, and are not intended to serve any other purpose. IRS issues ITIN‚Äôs to help individuals comply with the U.S. tax laws, and to provide a means to efficiently process and account for tax returns and payments for those not eligible for Social Security Numbers (SSNs).¬†
An ITIN does not authorize work in the U.S. or provide eligibility for Social Security benefits or the Earned Income Tax Credit.
Who needs an ITIN?
IRS issues ITIN‚Äôs to foreign nationals and others who have federal tax reporting or filing requirements and do not qualify for SSNs. A non-resident alien individual not eligible for a SSN who is required to file a U.S. tax¬†return¬†only to claim a refund of tax under the provisions of a U.S. tax treaty needs an ITIN.
Other examples of individuals who need ITIN‚Äôs include:
¬†¬†¬†‚ÄĘ¬†A nonresident alien¬†required to file¬†a U.S. tax return¬†
¬†¬† ‚ÄĘ¬†A U.S. resident alien (based on days present in the United States) filing a U.S. tax return¬†
¬†¬† ‚ÄĘ¬†A dependent or spouse of a U.S. citizen/resident alien
¬†¬† ‚ÄĘ¬†A dependent or spouse of a nonresident alien visa holder
If you are being put on the UW‚Äôs payroll please ask your school‚Äôs divisional payroll coordinator for your taxpayer idemtification requirements.
If you already have obtained or applied for either an SSN or ITIN then you are not eligible for the other as both are U.S. Taxpayer Identification Number and a person is only allowed to have one of these numbers, never both.
How do I know if I need an ITIN?
If you do not have a SSN and are not eligible to obtain a SSN, but you have a requirement to furnish a federal tax identification number or file a federal income tax return, you must apply for an ITIN.
If you have an application for a SSN pending, do not file Form W-7. Complete Form W-7 only if the Social Security Administration (SSA) notifies you that a SSN cannot be issued.
To obtain a SSN, see Form SS-5, Application for a Social Security Card. To get Form SS-5 or to find out if you are eligible to obtain a SSN, go to Social Security Administration or contact a SSA office. By law, an alien individual cannot have both an ITIN and a SSN.
IRS processes returns showing SSNs or ITIN‚Äôs in the blanks where tax forms request SSNs. IRS no longer accepts, and will not process, forms showing "SSA205c," "applied for," "NRA," blanks, etc.
Are ITINs valid for identification?
No. ITIN‚Äôs are for federal tax reporting only, and are not intended to serve any other purpose.
