Schedule 2 (Form 1040) is an essential supplement for taxpayers who owe additional taxes that aren’t directly listed on the face of the main Form 1040. Whether it’s self-employment tax, household employment taxes, or repayment of excess credits, Schedule 2 helps the IRS calculate your total tax liability accurately. In this guide, we’ll break down each part of Schedule 2, explain who needs to file it, and show how it connects to your overall tax return.
What Is Schedule 2 (Form 1040)?
Schedule 2 is used to report “additional taxes” that are not included in the standard income tax calculation lines on Form 1040. It is part of a series of supplemental schedules introduced by the IRS starting with the 2018 tax year, designed to streamline Form 1040.
Schedule 2 has two parts:
- Part I – Additional Taxes: Self-employment tax, unreported Social Security/Medicare tax, and more.
- Part II – Other Taxes: Household employment taxes, individual responsibility payments, and repayments of excess credits.
Who Should File Schedule 2?
You need to file Schedule 2 if any of the following apply to you:
- You are self-employed and owe self-employment tax
- You had a household employee and owe household employment taxes
- You received advance premium tax credits and must repay excess amounts
- You owe additional taxes on IRAs or other tax-favored accounts
- You owe uncollected Social Security or Medicare tax
- You are required to repay excess health coverage tax credits
Part I – Additional Taxes (Lines 1–6)
This section includes taxes commonly owed by self-employed individuals or those with special tax situations:
- Line 1: Alternative Minimum Tax (AMT) – If you are subject to AMT, this amount is calculated using Form 6251.
- Line 2: Excess Advance Premium Tax Credit Repayment – If you received more health insurance credit than you’re eligible for, use Form 8962 to compute repayment.
- Line 3: Add lines 1 and 2 – This is the total for Part I and gets carried to Form 1040, line 17.
Part II – Other Taxes (Lines 7–17)
Part II lists less common but important additional taxes:
- Line 4: Self-Employment Tax – Calculated using Schedule SE; applies if your net self-employment income is $400 or more.
- Line 5: Unreported Social Security and Medicare Tax – For tips not reported to your employer or taxes on group-term life insurance.
- Line 6: Additional Tax on IRAs or Other Tax-Favored Accounts – Use Form 5329 to compute penalties for early withdrawals or excess contributions.
- Line 7: Household Employment Taxes – Use Schedule H if you paid household workers (like a nanny or caregiver).
- Line 8: Repayment of First-Time Homebuyer Credit – Applicable to certain taxpayers who claimed the credit before 2010.
- Line 9: Health Coverage Individual Responsibility Payment – For tax years when applicable (no longer required under federal law starting in 2019, but some states may still require it).
- Line 10: Additional Medicare Tax – High earners may be subject to 0.9% additional Medicare tax; use Form 8959.
- Line 11: Net Investment Income Tax – Applies to higher-income individuals with significant investment income; use Form 8960.
- Line 12: Other Additional Taxes – From any applicable IRS forms not already listed.
- Line 13: Add all of the above taxes to get your total “Other Taxes.”
How Does Schedule 2 Integrate With Form 1040?
Once Schedule 2 is completed, totals from each part are carried to Form 1040:
- Part I Total: Goes on Line 17 of Form 1040
- Part II Total: Goes on Line 23 of Form 1040
This contributes to your total tax liability, which is then compared to payments and refundable credits to determine whether you owe taxes or are due a refund.
