Married Filing Separate in CA with military spouse outside CA

[Joe in AZ]

I am using ATX and to this point have avoided filing MFS for any clients. This year I have new clients in CA and the Spouse is in the military stationed in TX. I have contacted the CA FTB, the IRS, and ATX directly but can't get a good answer. CA states that military pay earned while stationed outside CA is not taxable to CA. However, I can't find a CA form to subtract out the military wages from the CA return, they are taxable at the Federal level. The CA FTB stated that to remove the military pay, I would need to file a 540 NR which means I have to file MFS for both individuals one as 540 and one 540NR. My question is, when completing the federal returns for each individual I am completing the 8958 to split up the community property income but this does not carry forward to the 1040 so I have to enter each persons 50% of CP wages and federal withholding. My question is, what do I put in boxes 3, 4, 5, and 6 for FICA and Medicare wages and withholding? This can't be the first time this has occurred right? Any help is greatly appreciated.

Drake has instructions for MFS.

You don't need to file MFS, you can use the 540NR and claim one as resident and one as nonresident.
