I have an itin number already how can i file my taxes

Yes, you can file your tax return with a current ITIN. 

When prompted for your Social Security number, simply enter your ITIN instead.

Because it's in the same 9-digit format as a Social Security number, you will be able to enter it without any problems.

Thank for the advice
