When filing your federal income tax return using Form 1040, you might qualify for additional credits and tax payments not listed on the main form. This is where Schedule 3 (Form 1040) – Additional Credits and Payments comes into play. It helps taxpayers claim a wide range of nonrefundable and refundable credits as well as report certain payments to reduce their overall tax liability or increase their refund.
What Is Schedule 3?
Schedule 3 is a supplemental form to Form 1040 that includes:
- Part I – Nonrefundable Credits: These reduce your tax bill but don’t generate a refund if they exceed your tax liability.
- Part II – Other Payments and Refundable Credits: These can generate a refund, even if you don’t owe taxes.
The totals from Schedule 3 are transferred to the relevant lines on Form 1040, influencing your tax due or refund amount.
Who Should File Schedule 3?
You should file Schedule 3 if you’re claiming any of the following:
- Foreign tax credit
- Education credits (American Opportunity or Lifetime Learning)
- Retirement savings contributions credit (Saver’s Credit)
- Child and dependent care credit
- Residential energy credits
- Net premium tax credit (from the Health Insurance Marketplace)
- Amounts paid with Form 8862, 8962, or 2439
Part I – Nonrefundable Credits (Lines 1–7)
These credits reduce the tax you owe but cannot result in a refund if they exceed your liability:
- Line 1: Foreign tax credit – Use Form 1116 to claim taxes paid to a foreign country.
- Line 2: Credit for child and dependent care expenses – Use Form 2441 to claim child or dependent care costs.
- Line 3: Education credits – Use Form 8863 for the American Opportunity Credit or Lifetime Learning Credit.

- Line 5: Residential energy credits – Use Form 5695 to claim home energy-efficient improvements.
- Line 6: Other credits – Include any other nonrefundable credits (e.g., elderly or disabled credit).
- Line 7: Add lines 1–6 – This total gets transferred to Line 20 of Form 1040.
Part II – Other Payments and Refundable Credits (Lines 8–13)
Refundable credits can result in a refund even if you have no tax liability:
- Line 8: Net premium tax credit – Use Form 8962 to reconcile health coverage subsidies.
- Line 9: Amount paid with a request for extension to file (Form 4868).
- Line 10: Excess Social Security or tier 1 RRTA tax withheld.
- Line 11: Other refundable credits – Include amounts from Forms 2439, 8885 (HCTC), or 8801 (Credit for Prior Year Minimum Tax).
- Line 12: Add lines 8–11 – This total goes on Line 31 of Form 1040.
How Schedule 3 Affects Your 1040 Tax Return
After completing Schedule 3, the totals from each part are transferred as follows:
- Part I total (Line 7): Goes to Form 1040, Line 20 – reducing your tax liability.
- Part II total (Line 12): Goes to Form 1040, Line 31 – increasing your refund or payment credits.
Inaccurate or missing Schedule 3 filings can lead to lost credits or processing delays.
Common Scenarios That Require Schedule 3
- You paid for higher education expenses and want to claim the American Opportunity or Lifetime Learning Credit.

Tips for Accurately Filing Schedule 3
- Use IRS-approved tax software – it will auto-include Schedule 3 based on your data.
- Double-check eligibility criteria for each credit – many have income phase-outs.
- Keep documentation of expenses such as tuition statements (Form 1098-T) and energy receipts.
- Attach any required supporting forms like 8863, 5695, or 1116.
Conclusion
Schedule 3 (Form 1040) allows taxpayers to claim additional credits and payments that go beyond the standard deductions and credits on the main Form 1040. If you qualify for educational credits, the foreign tax credit, the Saver’s Credit, or advanced health premium reconciliation, this schedule ensures those benefits are properly applied to your return. Whether you’re reducing your tax bill or increasing your refund, understanding and filing Schedule 3 correctly can make a meaningful difference.
