I am using Proconnect.

I have a client who is filing MFS, her spouse does not have a SSN or ITIN. I have marked the spouse's SSN as not applicable and clicked the box "Spouse is a nonresident alien and does not have an SSN/ITIN (MFS Only)". However, I am still getting this "Spouse's social security number is invalid. A valid SSN must be between 001-01-0001 through 665-99-9999 and 667-01-0001 through 899-99-9999 or must be a valid ITIN. US - Ref #54321" diagnostic error. I filed for her last year and cleared this up, but I am not sure how to fix it this year. The only difference is that she moved to the UK.
