What is the phaseout for the adoption credit?
If you are eligible to claim the adoption credit but your modified adjusted gross income for the 2006 tax year was between $164,410 and $204,410, you cannot claim the full $10,960. Instead, you can only claim some percentage of that amount - you should calculate your adoption credit using Form 8839 to determine precisely what your credit is.
If your modified adjusted gross income for the 2006 tax year was more than $19924,410, you cannot claim the adoption credit at all (that is, it’s totally phased-out).
