The credit and income limitations that apply to a carryforward are based on the limits in effect for the year the carryforward first arose, rather than the year or years in which the carryforward is claimed.  If you did not pay additional adoption expenses in a later year related to that adoption or adoption attempt, you cannot increase your carryforward amount in a later year.

The following table shows the maximum dollar limitation and modified adjusted gross income phaseout range for the previous seven years.
