I haven't sent mine off yet, although once I make copies of everything I'm planning to mail it tomorrow, so I don't know about the timeline for everything. But I do know from the IRS not accepting the documentation of expenses from our 2009 adoption, I am making sure I send everything possible to them! I am hoping our 2011 adoption will go smoothly though, because my oldest daughter was our foster child and by the time we finally got to adopt her, her age and ethnicity classified her as being "special needs", which means there is a set amount of the credit and we don't submit any receipts. All I'm supposed to submt is the adoption decree and the adoption assistance paperwork, but I'm submitting everything DSS sent us, including our receipt of payment for court costs, and copies of her old and current birth certificate. I'm not taking any chances this time. I figure it's best to send in all of the possible information so the IRS has no reason to contact me. Because if they do, I don't have any more information I can give them!
I still plan on submitting a revised 2010 return for our other daughter's adoption we finalized in 2009, but it won't be for the full amount because I no longer have the receipt for the homestudy, and they wouldn't accept the adoption paperwork that listed these expenses that was signed by the social worker. I assume I needed the actual receipt. But at least I do have the receipts from the attorney, so we'll see what happens with that. I'm also hoping the process this year won't be as bad as what I've heard from last year.
