What Is Schedule 3 (Form 1040)?

Schedule 3 (Form 1040) is an IRS attachment that reports additional credits and payments you claim on your federal income tax return. It captures both non‑refundable and refundable credits such as the foreign tax credit, education credits, the retirement savings contributions credit, and the premium tax credit.

Key Credits and Payments on Schedule 3

Understanding each line helps you maximize your tax benefits:

• Foreign Tax Credit (Line 1): Reduces U.S. tax on income taxed abroad.
• Child and Dependent Care Credit (Line 2): For expenses paid to care for qualifying dependents.
• Education Credits (Line 3): Includes the American Opportunity and Lifetime Learning credits.
• Retirement Savings Contributions Credit (Line 4): Rewards low‑to‑moderate income earners who contribute to retirement plans.
• Premium Tax Credit (Line 5): Helps offset health‑insurance premiums bought through the Marketplace.
