Step 3: Claiming Dependents on Your W-4
In Step 3, enter the total expected Child Tax Credit and Other Dependent Credit amounts you’ll claim on your tax return. The 2025 Child Tax Credit: $2,000 per qualifying child under age 17. Other Dependent Credit: $500 per qualifying person who is not a child under 17 (adult dependents, elderly parents, college students between 17–24). Enter the dollar total — not the number of dependents.
Step 3 W-4 entries and withholding reduction amounts
| Dependents | Step 3 Entry | Annual Withholding Reduction | Per Paycheck (Biweekly) |
|---|---|---|---|
| 1 child under 17 | $2,000 | ~$2,000 less | ~$77 less |
| 2 children under 17 | $4,000 | ~$4,000 less | ~$154 less |
| 3 children under 17 | $6,000 | ~$6,000 less | ~$231 less |
| 1 child + 1 adult dependent | $2,500 | ~$2,500 less | ~$96 less |
| 2 children + 1 adult dependent | $4,500 | ~$4,500 less | ~$173 less |
The Child Tax Credit phases out for higher incomes: for single filers above $200,000 and MFJ above $400,000, the $2,000 credit reduces by $50 for every $1,000 over the threshold. If you’re near these thresholds, enter the reduced credit amount in Step 3 — not the full $2,000 per child.
Divorced or Separated Parents: Who Claims the Child?
Only one parent can claim the Child Tax Credit per child per year. If you have a custody arrangement, establish which parent claims which children each year. The claiming parent enters the credit in Step 3; the non-claiming parent does not. Claiming dependents not legally yours results in the IRS disallowing the credit and potentially assessing penalties.
