When you file, you file using your ITIN number. Then when you enter the W2 you edit the social security number to reflect the number on your w2 and any other info. You may end up having to mail in the return. The IRS allows this. https://www.irs.gov/individuals/international-taxpayers/individual-taxpayer-identification-number-it...
- Tax returns filed with an Individual Taxpayer Identification Number reporting wages paid are required to show the Social Security Number under which the wages were earned. This creates an identification number (ITIN/SSN) mismatch. In the past, returns with this mismatch could only be filed on paper. Due to programming changes the IRS' e-file system can now accept these returns. The taxpayer's correct ITIN should be used as the identifying number at the top of Form 1040. When inputting W-2 information, the SSN should be entered exactly as shown on the Form W-2 issued by the employer. It is now possible to e-file a return with an ITIN/SSN mismatch.
