Form 8812 — Credits for Qualifying Children and Other Dependents
Form 8812 is used to calculate the Child Tax Credit (CTC), the Additional Child Tax Credit (ACTC — the refundable portion), and the Credit for Other Dependents. For tax professionals, the CTC is one of the most impactful credits for family clients — but the phase-out rules, refundability limits, and interaction with Form 8332 (dependency releases) require careful analysis.
Key Rules and Authority
| Rule | Detail |
|---|---|
| CTC Per Child | $2,000 |
| ACTC Refundable Amount | $1,700 |
| Phase-Out (MFJ) | $400,000 AGI |
| Phase-Out (Single) | $200,000 AGI |
| Phase-Out Rate | $50 per $1,000 over threshold |
| Credit for Other Dependents | $500 non-refundable |
CTC vs. ACTC — Refundable vs. Non-Refundable
The Child Tax Credit has two components: (1) the non-refundable CTC — up to $2,000 per qualifying child, which can reduce tax liability to zero but not below zero; and (2) the refundable Additional Child Tax Credit (ACTC) — up to $1,700 per qualifying child, which can generate a refund even if the taxpayer has no tax liability. The ACTC is calculated as 15% of earned income above $2,500, up to the maximum refundable amount. Families with multiple children and moderate earned income often receive the maximum ACTC as a refund. The credit phases out at $400,000 (MFJ) and $200,000 (single) at a rate of $50 per $1,000 of excess AGI.
