The Child Tax Credit for the year 2020 was up to $2,000 per qualifying child. The child must have been under 17 years old at the end of the tax year, and the credit was subject to income phaseouts starting at $200,000 for single filers and $400,000 for married couples filing jointly. The credit was partially refundable, meaning families who owed little or no federal tax could receive a refund of up to $1,400 per child through the Additional Child Tax Credit. Key points for 2020:

• Maximum credit: $2,000 per qualifying child
• Child must be under 17 years old by December 31, 2020
• Eligibility includes the child having a valid Social Security number and being claimed as a dependent
• Phaseout begins at $200,000 modified adjusted gross income (MAGI) for single filers, $400,000 for joint filers
• Refundable portion (Additional Child Tax Credit) capped at $1,400 per child

These rules applied as part of the tax code before the expansions made in 2021 under the American Rescue Plan, which temporarily increased the credit amount for that year only. For the standard 2020 tax year, the amounts mentioned above were in effect.
