I have been married since February and haven’t been paid BAH. How long will it take to process it, and will I get back pay?

SPC Robinson where are you stationed at now? There is no reason what so ever that you shouldn't have been paid BAH. This is what I would do as of now:

1) Go to DEERS and make sure that she is enrolled. Make sure they have everything that you need. Bring your marriage certificate with you, just to be safe.

2) After that I would go to your finance section at the base. Present your marriage certificate, your DEERS enrollment paperwork, and ask them what you need to have happen to get your back paid BAH.

3) I guess I should have put this first. Let your NCO know. That's the job that he/she is supposed to do in the first place. I'm sorry that you had to resort to posting about this in Rally Point.

Good luck and message me if you have any issues or questions.

Have you called DFAS? They are the ones that would know.
