The Advance Child tax Credit Payments were based upon information on your 2020 or 2019 federal tax returns. Family and life situations can be fluid throughout a given year. Here are a few examples:
a) Your income increased in 2021, so you didn’t qualify for the total Child Tax Credit amount.
b) Your filing status changed – got married, divorced, had a baby, adopted a child.
c) A qualifying child who resided with you in 2020, changed homes in 2021 and resided more than half the 2021 year with a different individual.
