When filing your federal income tax return using IRS Form 1040, you may be eligible for a variety of tax credits that can significantly reduce your tax liability or even increase your refund. Credits such as the Child Tax Credit (Form 8812), Saver’s Credit (Form 8880), and the Earned Income Credit requalification (Form 8862) each have their own specific forms and rules. Understanding how to correctly attach and report these forms is essential to filing an accurate and complete return. This blog will walk you through each of these commonly used credit forms and explain how to attach them properly to Form 1040.
Understanding Tax Credits and IRS Form 1040
Tax credits directly reduce the amount of tax you owe. Unlike deductions, which lower your taxable income, credits are subtracted from your actual tax bill. Some credits are refundable, meaning they can generate a refund even if your tax liability is zero. Others are nonrefundable and only reduce your liability to zero.
Form 1040 is the standard individual income tax return. If you claim certain credits, you must complete the corresponding credit form and include it with your return. The IRS uses these attached forms to verify your eligibility and calculate the appropriate credit amount.
Form 8862 – Information to Claim Certain Credits After Disallowance
Purpose: Form 8862 is required when you want to reclaim a credit that was previously denied due to improper or erroneous claims. This includes credits like:
- Earned Income Tax Credit (EITC)
- Child Tax Credit (CTC)/Additional Child Tax Credit (ACTC)
- Credit for Other Dependents (ODC)
- American Opportunity Tax Credit (AOTC)
If one of these credits was disallowed in a previous year due to a mistake or audit, you must file Form 8862 to show that you now qualify and to regain eligibility.
How to Attach Form 8862 to Form 1040:
- Complete Form 8862 using current year tax information.
- Answer all applicable questions about your dependents, filing status, and income.
- Include the completed Form 8862 with your Form 1040 filing.
- Electronically filed returns will automatically attach Form 8862 if prepared correctly in tax software.
- If filing by paper, attach Form 8862 behind Form 1040 and before any additional schedules or forms.
Failing to include Form 8862 when required will result in the credit being denied again.
Form 8880 – Credit for Qualified Retirement Savings Contributions
Purpose: Form 8880 allows eligible taxpayers to claim the Saver’s Credit for contributions to retirement accounts, such as:
- Traditional and Roth IRAs
- 401(k), 403(b), 457(b) plans
- Simple IRA and SEP IRA plans
The credit ranges from 10% to 50% of contributions, depending on your income and filing status, and is nonrefundable.
How to Attach Form 8880 to Form 1040:
- Fill out Form 8880 to calculate your credit based on adjusted gross income and eligible contributions.
- Enter the credit amount on Schedule 3 (Form 1040), Line 4.
- Transfer the Schedule 3 total to Form 1040, Line 20.
- Attach the completed Form 8880 behind Schedule 3.
Many tax software programs will generate this form automatically when you enter retirement contributions.
Form 8812 – Credits for Qualifying Children and Other Dependents
Purpose: Form 8812 is used to calculate the Child Tax Credit (CTC), Additional Child Tax Credit (ACTC), and Credit for Other Dependents (ODC). It applies if you are claiming dependents under age 17 or other qualifying individuals.
Key Features of Form 8812:
- Part I determines eligibility and refundable/nonrefundable portions.
- Part II calculates the refundable ACTC if you are due a refund exceeding your tax liability.
How to Attach Form 8812 to Form 1040:
- Complete Form 8812 based on number of children and income thresholds.
- Enter the credit amount on Form 1040, Line 19 for nonrefundable CTC and ODC.
- If ACTC applies, also fill in Schedule 8812 and Line 28 on Form 1040.
- Attach Form 8812 directly after the main Form 1040 and before additional schedules.
Form 8812 is crucial to claim the full Child Tax Credit, which can be worth up to $2,000 per child.
Other Common Credit Forms and Their Attachments
Form 8863 – Education Credits (AOTC and LLC)
- Use to claim the American Opportunity Credit or Lifetime Learning Credit.

- Credit is nonrefundable and goes on Schedule 3, Line 2.
- Attach Form 2441 after Schedule 3.

Filing Electronically vs. Paper Filing
Most tax software platforms automatically attach all applicable forms when you e-file your return. The forms are generated based on your answers and included in the correct order. This reduces the risk of errors and speeds up processing.
If you are filing a paper return, you should follow the IRS’s general order of assembly:
- Form 1040 (including all schedules)
- Form 8812
- Schedule 3 and its supporting credit forms (e.g., Forms 8880, 8863, 2441)
- Additional forms like 8862, 8962, and 5695
- Attach forms in numeric order behind Form 1040
Always include your name and Social Security Number on each form, especially if submitting by mail.
Tips to Avoid Rejection or Delays
- Double-check eligibility: Each credit has unique requirements for income limits, filing status, and documentation.
- Use current forms: Only use the version of each form for the tax year you’re filing.
- Attach all pages: Don’t submit only partial forms—include all relevant pages even if some sections are blank.
- Don’t staple forms: If mailing, use paperclips instead of staples to keep forms organized.
- Keep copies: Retain a full copy of your completed return with all attached credit forms for your records.
Conclusion: Maximize Your Credits, File Them Right
Tax credits can provide significant savings and refunds—but only if filed properly. Whether you’re trying to reclaim a denied Earned Income Credit with Form 8862, claiming the Child Tax Credit with Form 8812, or taking advantage of retirement contributions via Form 8880, it’s essential to attach these forms accurately to your IRS Form 1040. Proper filing ensures faster processing, avoids rejections, and guarantees you receive every dollar you’re entitled to.
When in doubt, use professional tax software or consult a tax preparer to ensure that all credits are correctly calculated and forms properly attached. A small oversight could mean the loss of a valuable refund or delay in processing your return.
