So this is more of a curiosity question- I know that if we are married and file separately and live in a community property state I will need to submit my pay stub as an alternative documentation of income. Okay. I am trying to figure out what the monthly payment will be, but I’m not sure if they are going to just use my gross pay from the pay stub, or somehow calculate my AGI based on my pay (my AGI is always significantly less than my total gross pay for the year) and use that to calculate my monthly payments.

Anyone doing this now who can give me a heads up?
