IRS Form 1040 (Schedule 2) – Additional Taxes – If you’re filing your U.S. individual income tax return using Form 1040, 1040-SR, or 1040-NR, you might need to attach IRS Form 1040 Schedule 2 to report additional taxes that aren’t covered on the main form. This schedule is essential for taxpayers who owe special taxes like self-employment tax, alternative minimum tax (AMT), or recapture of certain credits. Understanding how to use Schedule 2 can help you avoid penalties and ensure accurate filing. In this SEO-optimized guide, we’ll break down what Schedule 2 is, who needs it, how to fill it out, and key updates for the 2025 tax year.
Whether you’re self-employed, a high-income earner, or dealing with household employment taxes, this article provides step-by-step insights based on official IRS guidelines. Let’s dive in to make your tax preparation smoother.
What is IRS Form 1040 Schedule 2?
IRS Form 1040 Schedule 2, titled “Additional Taxes,” is a supplementary form used to calculate and report taxes beyond the standard income tax computed on Form 1040. It consists of two main parts: Part I for certain additions to tax and AMT, and Part II for other specific taxes like self-employment or net investment income tax. The totals from this schedule flow directly to lines 17 and 23 (or 23b for Form 1040-NR) on your main tax return.
This form helps the IRS capture taxes on unique income sources or situations, ensuring compliance with tax laws. For example, if you’ve received excess premium tax credits or have unreported tip income, Schedule 2 is where you’ll account for the additional liability. It’s attached only if you owe these taxes; otherwise, you can skip it.
Key features of Schedule 2 include:
- References to other forms like Schedule SE (self-employment tax) or Form 6251 (AMT).
- Checkboxes for exemptions or special situations.
- A section for “other additional taxes” to cover miscellaneous recaptures or penalties.

Who Needs to File Schedule 2?
Not everyone filing Form 1040 needs Schedule 2. You should file it if you owe any of the following additional taxes:
- Alternative minimum tax (calculated on Form 6251).
- Excess advance premium tax credit repayment (from Form 8962).
- Self-employment tax (from Schedule SE).
- Additional Medicare tax or net investment income tax (from Forms 8959 and 8960).
- Household employment taxes (from Schedule H).
- Taxes on IRAs, HSAs, or other tax-favored accounts (from Form 5329).
- Recapture of credits like low-income housing or clean vehicle credits.
- Unreported social security and Medicare taxes on tips or wages.
High-income earners (e.g., wages over $200,000 for singles) are particularly likely to need this schedule due to AMT, additional Medicare tax, or net investment income tax thresholds. Self-employed individuals must use it to report self-employment tax if their net earnings exceed $400.
Even if you don’t owe regular income tax, you might still need to file a return with Schedule 2 if you have these special taxes. Tax software like TurboTax or FreeTaxUSA can automatically generate it based on your inputs. Consult IRS Publication 17 or a tax professional if unsure.
