Advanced tax credits for children were based on 2020 tax returns, so divorced or unmarried parents who alternate claiming dependents may have received excess advance CTC payments if they do not claim the child this year.
The Safe Harbor Repayment Protection provision provides protection against repayment of this excess amount for low-income individuals. The income thresholds are $40,000 for single filers, $50,000 for households and $60,000 for joint filers.
If your income exceeds these thresholds for your filing status, you may have to repay them.
