What Is IRS Form 1040 Schedule 2?

Schedule 2 is an attachment to the main IRS Form 1040 (the U.S. Individual Income Tax Return), and it is used to report additional taxes that the standard 1040 form does not capture. Specifically, taxpayers must use it if they owe certain taxes beyond regular income tax, such as the Alternative Minimum Tax (AMT), self-employment tax, or repayment of excess advance premium tax credits.

Quick Facts:

  • Firstly, Form 1040 Schedule 2 applies only to taxpayers with additional tax liabilities.
  • Secondly, you must file it alongside Form 1040, Form 1040-SR, or Form 1040-NR.
  • Moreover, the form is divided into two parts: Part I – Tax and Part II – Other Taxes.

Why Was Schedule 2 Created?

Back in 2018, the IRS streamlined tax reporting by shortening Form 1040 and creating schedules to handle details previously on the main form. Consequently, Schedule 2 now covers many “other taxes,” which simplifies and organizes tax filing, making the process less overwhelming.

Who Needs to File Schedule 2 (Form 1040)?

You may need to file Schedule 2 if you owe any of the following:

  • Alternative Minimum Tax (AMT)
  • Repayment of excess advance premium tax credits
  • Self-employment tax
  • Unreported Social Security or Medicare tax
  • Taxes on IRAs or other retirement accounts
  • Household employment taxes (for example, if you employ a nanny or caregiver)
  • Repayment of the first-time homebuyer credit
  • Additional Medicare tax or net investment income tax

Detailed Breakdown: Schedule 2, Form 1040 (2024)

Part I – Tax

  • Line 1: Alternative Minimum Tax (AMT). If your income is high enough, you owe AMT. Therefore, you must attach Form 6251.
  • Line 2: Excess advance premium tax credit repayment. If you received more credit than eligible, you must repay the excess. Accordingly, attach Form 8962.
