My wife and I will file the state tax return jointly.
She is not eligible for a SSN, so we mailed W-7 form with federal tax return to IRS to request a ITIN for her. The problem is, it is likely the ITIN won't be assigned before April 15th.
Should we file an extension for my state tax return? Is there a chance that I can still file state tax return when ITIN is in progress?
