I currently owe federal taxes and have submitted my 1040 along with my spouses W-7 form (ITIN number request). Unfortunately I have not received a response from IRS and will more than likely not have the ITIN number before this years due date. When processing to pay taxes online, there’s a box to enter the ITIN number if filling jointly. Should I proceed to pay leaving this blank? Should I file for an extension? Should I wait until the ITIN is received to pay even if it’s after the final day?
