Why am I not getting child tax credit but getting additional child tax credit?

You're likely getting the Additional Child Tax Credit (ACTC) but not the main Child Tax Credit (CTC) because the CTC is non-refundable and reduces your tax bill to zero, while the ACTC is a refundable part that gives you cash back, often when your income is too low for the full CTC but you have earned income (usually $2,500+). The ACTC kicks in for the unused portion of the CTC (up to a limit, around $1,700 for 2025), acting as a refund for a portion of your earned income.
