Elaborate Frequently Asked Questions (FAQ)
What is an IRS Individual Taxpayer Identification Number (ITIN)?
An ITIN is a 9-digit tax processing number issued by the IRS under 26 U.S.C. 6109 for individuals who are required to have a US taxpayer identification number but are not eligible for a Social Security Number (SSN).
Why do H-4 and L-2 spouses apply for an ITIN?
H-4 and L-2 spouses without an SSN apply for an ITIN to allow the principal worker to file tax returns under the 'Married Filing Jointly' status, significantly reducing total federal income tax liabilities.
Do ITIN numbers expire?
Yes. Under PATH Act regulations, any ITIN not used on a US federal tax return at least once in three consecutive calendar years expires on December 31 of the third year.
