Late to the Adoption Tax Credit party

This. Two special needs adoptions from 2005 should net you $21,260. Since you can usually only amend 3 years back and they are making an exception in this case, I would absolutely want a CPA to be on my side. If your kids get a monthly stipend and you had no tax liability 2005-2010, you should absolutely qualify. Another thought ... Have you tried getting help from a Tax Advocate? I'm not sure that they can help with the form, but may be able to point in the direction of free/low cost resources. Good luck!
