I know that you can use estimates from 2011; however, my situation is a little different and it would be very difficult to estimate.
1. My parents recently got divorced so they are filing separately for 2012.
2. My dad (the custodial parent) is self employed so his income fluctuates from year to year.
I know we are supposed to use estimates, but because of these two circumstances, I don't know how accurate the estimates will be. Is it ok if I submit estimates for the CSS Profile then send in the tax returns and other documents afterwards? I need to get it in by February 1 for USC, but my dad won't be able to file taxes until the day it's due.
