IRS-Accurate Checklist: Form 1040 Schedule 2 (Additional Taxes) — Tax Year 2024
Year-Specific Context (2024)
2024 Form Uniqueness
Schedule 2 for 2024 introduces mandatory reporting of clean vehicle credit repayments (new and previously owned) on lines 1b–1c via Form 8936, reflecting legislative changes under the Inflation Reduction Act; this form is the final year first-time homebuyer credit repayments are reported (Form 5405, line 10), as the 15-year repayment window closes for homes purchased in 2008.
2024-Specific Rules Affecting This Form
Repayments of new and previously owned clean vehicle credits transferred to registered dealers must be reported on Schedule 2, lines 1b and 1c, with Form 8936 and Schedule A (Form 8936) attached. 2024 is the final tax year to report first-time homebuyer credit repayment on line 10 using Form 5405.
Mandatory Year Audit: 2024 Rules Applicable to Schedule 2
TCJA Rules (2018–2025)
The Alternative Minimum Tax (AMT) exemption for 2024 is $85,700 (single), $133,300 (married filing jointly), and $66,650 (married filing separately). These amounts automatically adjust annually for inflation and are cited in the 2024 instructions for Form 6251, which must be attached when AMT is owed.
Energy and Clean Vehicle Credit Changes
Repayment of new and previously owned clean vehicle credits is now reported on Schedule 2, lines 1b–1c (not elsewhere on Form 1040), with corresponding Forms 8936 and Schedule A (Form 8936) attached.
First-Time Homebuyer Credit Sunset
Repayment continues on line 10 (Form 5405 if required), but 2024 is the final year of the 15-year repayment period for homes purchased in 2008.
ARPA and EIP Reconciliation
Not applicable to Schedule 2 (Economic Impact Payments were reconciled in prior years).
ACA Shared Responsibility
Not applicable (individual mandate penalty ended).
Mandatory Form Audit: Schedule 2 Limitations

Ten-Step Checklist: 2024 Schedule 2 Preparation
Step 1: Gather Documentation for Part I (Tax)
Collect Form 6251 (if Alternative Minimum Tax applies); Form 8962 (Premium Tax Credit reconciliation if you received advance premium tax credit through the Marketplace); and Form 8936 with Schedule A (Form 8936) if you transferred a new or previously owned clean vehicle credit to a dealer in 2024.
Step 2: Verify AMT Applicability
Complete the AMT worksheet in the 2024 Form 6251 instructions to determine if income exceeds the 2024 exemption threshold ($85,700 single; $133,300 MFJ; $66,650 MFS). If AMT is owed, enter the amount on Schedule 2, line 2, and attach Form 6251.
Step 3: Reconcile Premium Tax Credit
If 1095-A from the Marketplace was received showing advance premium tax credit payments, complete Form 8962 to calculate any excess repayment due. Enter net repayment amount on Schedule 2, line 1a.
Step 4: Report New and Previously Owned Clean Vehicle Credit Repayments
If you transferred a new or previously owned clean vehicle credit to a registered dealer and later determined you no longer qualify for the credit, enter the repayment amount on Schedule 2, line 1b (new vehicle) or line 1c (previously owned vehicle), with Form 8936 and Schedule A (Form 8936) attached.
Step 5: Gather Documentation for Part II (Other Taxes)
Collect Schedule SE (self-employment tax); Form 4137 (unreported tips); Form 8919 (uncollected wages tax); Form 5329 (IRA or tax-favored account distributions if required); Schedule H (household employment taxes); Form 5405 (first-time homebuyer credit repayment—final year, 2024 only); Form 8959 (Additional Medicare Tax); Form 8960 (Net Investment Income Tax); Form 8611 (low-income housing credit recapture); and Form 965-A (Section 965 net tax liability) if applicable.
Step 6: Calculate Self-Employment Tax
Complete Schedule SE for all self-employment income ($400 or more). Enter total self-employment tax on Schedule 2, line 4; attach completed Schedule SE.
Step 7: Report Social Security and Medicare Taxes
Suppose you received unreported tip income, complete Form 4137 and enter it on Schedule 2, line 5. Suppose an employer failed to withhold Social Security and Medicare taxes on wages, complete Form 8919 and enter on Schedule 2, line 6. Sum lines 5 and 6, and join the result on line 7.
Step 8: Report Household Employment Taxes (if Applicable)
If you paid any household employee (nanny, housekeeper, caregiver) $2,700 or more in 2024 cash wages, complete Schedule H and enter the total household employment tax on Schedule 2, line 9.
Step 9: Report First-Time Homebuyer Credit Repayment (Final Year)
If you claimed the first-time homebuyer credit for a home purchased in 2008 and the house was disposed of or ceased to be your principal residence in 2024, calculate the repayment amount and enter it on Schedule 2, line 10. Form 5405 is required only if you disposed of the home; otherwise, enter repayment directly on line 10. Note: 2024 is the final tax year for this credit.
Step 10: Complete Part II Totals and Verify Entries
For additional taxes not covered by lines 4–16 (e.g., additional Medicare tax from Form 8959, line 18; Net Investment Income Tax from Form 8960, line 21; recapture of low-income housing credit from Form 8611, line 8), enter on lines 11, 12, and 16, respectively. Complete lines 17a–17z for any other additional taxes. Sum all applicable lines and enter the total on line 21, then transfer this amount to Form 1040, line 23 (or equivalent line on 1040-SR or 1040-NR). Verify all required forms are attached. Ensure Schedule 2 is signed and dated (if a separate signature line is provided) and assembled in sequence with your complete Form 1040, 1040-SR, or 1040-NR return before mailing to the address provided in the 2024 Form 1040 instructions for your state.
Form-Specific Limitations
Schedule 2 cannot be filed independently; it must be accompanied by Form 1040, 1040-SR, or 1040-NR. Nonresident aliens filing Form 1040-NR should report tax on non-effectively connected income on Schedule 2, line 17o, and consult Form 1040-NR instructions for restrictions on credits and deductions. Self-employed individuals with net earnings of $400 or more must file Schedule SE; Schedule 2 alone is insufficient to report this obligation.
