Washington state’s Working Families Tax Credit (WFTC) is not only available to people who have a Social Security Number (SSN), but also to those who file their federal taxes with an Individual Taxpayer Identification Number (ITIN).
Video: Applying with an ITIN (3:09)
An ITIN is a number issued by the IRS to individuals who are required to report federal taxes to the IRS but are not eligible for an SSN. An ITIN is issued regardless of immigration status.
To qualify for the WFTC, you must apply using a valid ITIN or valid SSN. If you are including your spouse or children on the application, they must also have a valid ITIN or valid SSN.
If you are waiting for the Internal Revenue Service (IRS) to issue an ITIN to you or your family members, you may still submit your application by the deadline of December 31 each year. We will hold your application until you provide us with your ITIN information.
