2020 Schedule 2 (Form 1040) — IRS-Accurate Checklist
Why 2020 Schedule 2 Is Unique
Schedule 2 applies to Form 1040-NR (for nonresident aliens) for the first time in 2020, consolidating the alternative minimum tax, premium tax credit reconciliation, self-employment tax, household employment tax, and Section 965 installments. Form 8962 is a mandatory attachment for excess advance premium tax credit repayment. Additional Medicare Tax (Form 8959) reporting has expanded due to the wage threshold structure.
2020 Year-Specific Programs Affecting Schedule 2
The 2020 unemployment compensation exclusion (up to $10,200 per taxpayer if modified AGI under $150,000) is reported on Schedule 1, not Schedule 2, but reduces overall income subject to specific calculations. The Recovery Rebate Credit (Economic Impact Payment reconciliation) is claimed on Form 1040, line 30, not on Schedule 2, but must be reconciled separately. Premium tax credit excess repayment via Form 8962 must be reported on Schedule 2 line 2 if 2020 advance marketplace payments exceed calculated 2020 premium tax credit eligibility.
Ten-Step Checklist
Step 1: Verify Filing Form and Residency Status
Schedule 2 attaches only to Form 1040, Form 1040-SR (for taxpayers age 65 or older at year-end, born before January 2, 1956), or Form 1040-NR (nonresident aliens). Confirm your Social Security number and filing status selection before completing Schedule 2.
Step 2: Determine Whether Schedule 2 Is Required
Complete and file Schedule 2 only if you have additional tax liability in one or more categories: alternative minimum tax (Form 6251 line 11), excess advance premium tax credit repayment (Form 8962 line 29), self-employment tax (Schedule SE line 12), unreported social security and Medicare tax on tips or wages (Form 4137 or Form 8919), additional tax on IRAs or qualified retirement plans (Form 5329), household employment taxes (Schedule H line 25), first-time homebuyer credit repayment (Form 5405), Additional Medicare Tax (Form 8959), Net Investment Income Tax (Form 8960), or Section 965 net tax liability installment (Form 965-A, line 1f). If the above do not apply, omit Schedule 2.
Step 3: Complete Part I (Alternative Minimum Tax)
If you are subject to alternative minimum tax, complete Form 6251 (Alternative Minimum Tax—Individuals) and attach it to your return. Enter the amount from Form 6251, line 11, on Schedule 2, line 1. If you have no alternative minimum tax, leave line 1 blank.
Step 4: Complete Part I (Excess Advance Premium Tax Credit Repayment)
If you enrolled in a qualified health plan through the Marketplace and received advance payments of the premium tax credit (shown on Form 1095-A), complete Form 8962 (Premium Tax Credit) to reconcile advance payments with your 2020 premium tax credit. If advance payments exceed your 2020 credit, enter the excess repayment amount on Schedule 2, line 2, and attach Form 8962 to your return. If your credit exceeds advance payments, report the credit difference on Schedule 3, not Schedule 2.
Step 5: Add Part I Lines and Transfer to Main Return
On Schedule 2, line 3, add lines 1 and 2. Transfer the amount from line 3 to Form 1040 line 17, Form 1040-SR line 17, or Form 1040-NR line 17, depending on which primary return you filed. If both lines 1 and 2 are blank or zero, line 3 is zero.
Step 6: Gather Part II Supporting Documents
Before completing Part II (lines 4–10), collect the following documents: Schedule SE (Form 1040) if you had self-employment income; Form 4137 if you received cash or charge tips of $20 or more in any month and did not report all tips to your employer; Form 8919 if you received wages reported on Form 1099-MISC or 1099-NEC without tax withholding; Form 5329 if you took early IRA distributions, made excess contributions, or had other prohibited transactions; Schedule H (Form 1040) if you paid wages to household employees; Form 5405 if you sold a home purchased under the first-time homebuyer credit or ceased using it as your main home; Form 8959 if your wages exceed the Additional Medicare Tax threshold; Form 8960 if you have investment income subject to Net Investment Income Tax; Form 965-A if you have Section 965 tax liability installments.
Step 7: Complete Part II, Lines 4–5 (Payroll and Wage Taxes)
Line 4: Enter self-employment tax from Schedule SE (Form 1040) line 12. If you are married and filing separately, and you and your spouse had community income, file a separate Schedule SE for each spouse.
Line 5: If you had unreported tips or wages without employer withholding, complete Form 4137 (for unreported tips) or Form 8919 (for wages), and enter the social security and Medicare tax due on this line.
Step 8: Complete Part II, Lines 6–9 (Other Additional Taxes)
Line 6: Enter additional tax on IRAs and retirement plans from Form 5329 (if required).
Line 7a: Enter household employment taxes from Schedule H (Form 1040) line 25.
Line 7b: Enter first-time homebuyer credit repayment from Form 5405 if applicable.
Line 8: Enter Additional Medicare Tax from Form 8959, Net Investment Income Tax from Form 8960, or other taxes per IRS instructions; specify codes.
Line 9: Enter Section 965 net tax liability installment from Form 965-A, line 1f.
Step 9: Add Part II and Attach Supporting Forms
On Schedule 2 line 10, add lines 4 through 8 and enter the total. Transfer this amount to Form 1040 line 23, Form 1040-SR line 23, or Form 1040-NR line 23b. Assemble and attach all supporting schedules and forms in this order: Schedule 2 (top); Form 6251 (if line 1 has an entry); Form 8962 (if line 2 has an entry); Schedule SE (if line 4 has an entry); Form 4137 or Form 8919 (if line 5 has an entry); Form 5329 (if line 6 has an entry); Schedule H (if line 7a has an entry); Form 5405 (if line 7b has an entry); Form 8959 (if line 8 includes code a); Form 8960 (if line 8 includes code b); Form 965-A (if line 9 has an entry). If you are a nonresident alien, also include Form 1040-NR Schedule OI (Other Information).
Step 10: Sign, Date, and File the Complete Return
Sign and date your Form 1040, Form 1040-SR, or Form 1040-NR in black ink (do not sign Schedule 2; it has no signature lines). Include your preparer’s name, signature, and Preparer Tax Identification Number (PTIN) if a paid preparer assisted. Mail or file the complete return package—main form, all numbered schedules, all supporting forms, Schedule 2, and any required tax payment or extension—to the correct IRS address per the 2020 IRS “Where to File” instructions based on your filing status and whether you owe tax or expect a refund.
Form-Specific Limitations
Nonresident aliens filing Form 1040-NR may have restricted access to certain credits and tax benefits reflected on Schedule 2; review Form 1040-NR instructions and Publication 519 (U.S. Tax Guide for Aliens) for your specific residency classification and allowed entries. Self-employed individuals with net earnings from self-employment under $400 in the tax year are not required to file Schedule SE and therefore do not report on Schedule 2 line 4, regardless of other Schedule 2 entries. Married filing separately filers: If you and your spouse both had self-employment income or community income, each spouse must file a separate Schedule SE (Form 1040) if net self-employment earnings equal or exceed $400 for that spouse.
2020 Line Redesigns and Updates
Schedule 2 applicability: Prior approach: Form 1040-NR used different schedules; Schedules 1, 2, and 3 did not apply uniformly. 2020 change: Form 1040-NR now uses Schedules 1, 2, and 3 beginning in 2020, aligning with the Form 1040 structure. Change type: Redesigned.
Part I, line 2: Prior approach: Excess premium tax credit repayment introduced with ACA, but reconciliation requirements clarified annually. 2020 change: Explicit requirement: attach Form 8962 to reconcile advance payments from Marketplace with the 2020 computed premium tax credit. Change type: Clarified.
Part II, line 8: Prior approach: Form 8959 and Form 8960 referenced, but codes not explicitly delineated. 2020 change: Codes (a) Form 8959, (b) Form 8960, (c) other per instructions. Change type: Updated.
