Schedule 8812 (2020) Instructions: Additional Child
Tax Credit Guide
Schedule 8812 allows eligible taxpayers to claim the Additional Child Tax Credit, a refundable portion of the Child Tax Credit. The 2020 form included an optional election to use 2019 earned income for ACTC calculations, a provision enacted to assist taxpayers whose 2020 income declined due to COVID-related economic disruptions.
Economic Impact Payments issued in 2020 under the CARES Act required reconciliation on
Form 1040 through the Recovery Rebate Credit on line 30. Recovery Rebate Credit and
Schedule 8812 function as distinct credits with independent calculations that are not influenced by one another.
Qualifying Child Requirements
Each child claimed on Schedule 8812 must meet the qualifying child definition per Form 1040 requirements and be under age 17 as of December 31, 2020. Gather birth certificates, Social
Security cards, or official identification documents for all dependents before completing the schedule.
Every qualifying child must have a valid Social Security number issued before the due date of your 2020 return, including extensions. Children with Individual Taxpayer Identification Numbers do not qualify for ACTC under the 2020 rules and cannot be used to claim this refundable credit.
Earned Income Documentation
Collect all W-2s, Schedule C net profit statements, Schedule E rental income reports, and
1099-NEC or 1099-MISC self-employment income forms before starting Schedule 8812. ACTC calculation requires earned income documentation because the credit is computed as 15% of earned income exceeding $2,500.
Unearned income, such as interest, dividends, or capital gains, does not qualify when determining ACTC eligibility or calculating the refundable credit amount. Wages, salaries, tips, and net self-employment income constitute earned income for Additional Child Tax Credit eligibility in 2020.
Modified AGI Calculation
Calculate modified adjusted gross income using the standard definition established by the Tax
Cuts and Jobs Act without any temporary modifications. Modified AGI equals your adjusted gross income from Form 1040 line 11 plus certain exclusions for foreign earned income, foreign housing costs, and income from Puerto Rico or American Samoa.
No COVID-related changes to the modified AGI definition existed in 2020, and the calculation follows the same methodology used in all TCJA years from 2018 through 2025. The standard modified AGI rules apply uniformly across all instructions for 2020 Schedule 8812 filings.
Phase-Out Thresholds
The Child Tax Credit phases out when modified AGI exceeds specific thresholds based on filing status. Phase-out begins at $200,000 for single filers, head of household filers, or married filing separately.
Married filing jointly filers face a phase-out when modified AGI exceeds $400,000, with the credit reducing by $50 for each $1,000 above the threshold. These phase-out thresholds and rates remained identical to prior TCJA years and were not temporarily modified for 2020.
Required Form 1040 Schedules
Complete the following schedules when applicable before filing Schedule 8812
- Attach Schedule 1 if claiming income not reported on lines 1 through 9b of Form 1040 or
claiming adjustments to income.
- Attach Schedule 2 if claiming certain credits or owing additional taxes beyond the
standard income tax calculation.
- Attach Schedule 3 if claiming nonrefundable credits beyond the Child Tax Credit or
Credit for Other Dependents.
Filing Restrictions
Schedule 8812 cannot be filed independently and must accompany a complete Form 1040 or
Form 1040-SR. Taxpayers filing Form 2555 for foreign earned income exclusion cannot claim
ACTC and should stop before completing Schedule 8812.
Form 1040-NR filers generally cannot claim the Additional Child Tax Credit under standard rules. Certain nonresident aliens who elect to be treated as resident aliens when married to a
U.S. citizen or resident may file Form 1040 and become eligible for the credit.
Prior Year Earned Income Election
Enter your earned income from wages, salaries, tips, and net self-employment income on
Schedule 8812 line 6a using either 2020 or 2019 amounts. You may elect to use your 2019 earned income instead of your 2020 earned income when calculating ACTC if your 2019 earned income exceeded your 2020 earned income.
This election helps taxpayers whose income declined in 2020 maintain eligibility for the refundable credit and represents the primary COVID-related modification to the 2020 instructions. To make this election, write “PYEI” and the amount of your 2019 earned income in the space next to Form 1040 line 28.
Credit Calculation Methods
Calculate the ACTC by multiplying earned income exceeding $2,500 by 15% to determine your refundable credit amount. The maximum ACTC equals $1,400 per qualifying child for 2020 under standard calculation rules.
Taxpayers with three or more qualifying children must complete Part II of Schedule 8812, which uses an alternative calculation based on social security and Medicare taxes withheld. For families with multiple children and substantial employment tax withholding, the alternative formula may result in a greater refundable credit amount.
Tax Return Assembly and Filing Procedures
Attach Schedule 8812 to your 2020 tax return along with all required supporting schedules and forms in the order specified by IRS instructions. Ensure line entries on Schedule 8812
cross-reference Form 1040 and attached schedules accurately to avoid processing delays that could affect your tax return.
Sign and date both Form 1040 and Schedule 8812 before filing your tax return with the IRS. The
IRS cannot issue refunds before mid-February 2021 for returns claiming ACTC, and this delay applies to the entire refund amount on your tax return, regardless of other credits claimed.
Federal Income Tax and Recovery Rebate Credit
The Recovery Rebate Credit reconciles Economic Impact Payments received in 2020 on Form
1040 line 30 using a separate worksheet independent from Schedule 8812. Verify the total EIP amount on IRS Notice 1444 or Notice 1444-B before completing the Recovery Rebate Credit
Worksheet to ensure accurate reconciliation of your federal income tax liability.
Based on 2020 tax information, the worksheet compares the credit amount you qualify for with the advance payments you have received. Any discrepancies between the two amounts will result in an increase or decrease in your refund. Both credits can be claimed on the same tax return, and claiming one does not preclude eligibility for the other.
Tax Years and Reporting Requirements
Schedule 8812 requirements remained consistent across multiple tax years under the Tax Cuts and Jobs Act framework from 2018 through 2025. The 2020 tax year introduced the optional prior year earned income election as the sole modification to standard ACTC calculation procedures used in other tax years.
Tax years 2018, 2019, 2020, and subsequent tax years through 2025 all utilize identical phase-out thresholds and modified AGI definitions for Schedule 8812 purposes. Understanding how tax years align with TCJA provisions helps taxpayers prepare accurate returns and claim appropriate refundable credits across multiple filing periods.
Frequently Asked Questions
Can I use my 2019 income to calculate the Additional Child Tax Credit for
2020?
Yes, you may elect to use your 2019 earned income instead of your 2020 earned income when calculating ACTC if your 2019 earned income was higher. Write “PYEI” and your 2019 earned income amount in the space next to Form 1040 line 28 on your tax return to make this election.
Do Economic Impact Payments affect my Schedule 8812 calculations?
No, Economic Impact Payments do not affect ACTC calculations on Schedule 8812. EIPs are reconciled separately through the Recovery Rebate Credit on Form 1040 line 30, which operates independently from Schedule 8812 on your tax return.
What is the minimum earned income required to claim ACTC?
You must have earned income of at least $2,500 to qualify for the Additional Child Tax Credit.
The ACTC equals 15% of your earned income exceeding $2,500, up to $1,400 per qualifying child for the 2020 tax year.
Can children with Individual Taxpayer Identification Numbers qualify for
ACTC?
No, children with ITINs do not qualify for ACTC under the 2020 rules. Each qualifying child must have a valid Social Security number issued before the due date of your 2020 tax return, including extensions, to claim this refundable credit.
Did the modified AGI calculation change for Schedule 8812 in 2020?
No, the modified AGI calculation for Schedule 8812 instructions for 2020 remained the same as all other TCJA tax years. No temporary COVID-related modifications to the modified AGI definition existed, and standard TCJA phase-out thresholds of $200,000 for single filers and
$400,000 for joint filers applied consistently across tax years.
