IRS Schedule B Form – In the world of U.S. tax filing, understanding how to report investment income is crucial for compliance and avoiding penalties. IRS Schedule B (Form 1040), titled “Interest and Ordinary Dividends,” plays a key role in this process. This form helps taxpayers detail their taxable interest, ordinary dividends, and certain foreign financial activities when filing their federal income tax return. Whether you’re a beginner investor or managing complex portfolios, mastering Schedule B ensures accurate reporting and can help optimize your tax situation. In this SEO-optimized guide, we’ll cover everything you need to know about Schedule B for the 2025 tax year, including who must file, step-by-step instructions, and tips to avoid common pitfalls.
What Is IRS Schedule B (Form 1040)?
Schedule B is an attachment to Form 1040 or 1040-SR, used primarily to report interest and dividend income that exceeds certain thresholds. It’s divided into three main parts: taxable interest (Part I), ordinary dividends (Part II), and questions about foreign accounts and trusts (Part III). The form ensures the IRS receives detailed information on income sources, which helps verify totals reported on your main tax return.
Interest income includes earnings from savings accounts, bonds, and loans, while ordinary dividends come from investments like stocks or mutual funds. Part III addresses compliance with foreign asset reporting rules, which is increasingly important in a global economy. For the 2025 tax year, there are no major structural changes to Schedule B, but taxpayers should note broader updates to Form 1040, such as increased standard deductions and adjustments to credits that may indirectly affect overall filing.

Who Needs to File Schedule B?
Not everyone with interest or dividend income must file Schedule B—it’s required only under specific conditions to streamline reporting for low-income amounts. You must attach Schedule B to your Form 1040 if any of the following apply for the 2025 tax year:
- Your taxable interest or ordinary dividends exceed $1,500.
- You received interest from a seller-financed mortgage where the buyer used the property as a personal residence.
- You’re reporting accrued interest from a bond.
- You’re reporting original issue discount (OID) in an amount less than shown on Form 1099-OID.
- You’re reducing interest income due to amortizable bond premium.
- You’re claiming an exclusion for interest from series EE or I U.S. savings bonds issued after 1989.
- You received interest or dividends as a nominee (on behalf of someone else).
- You have a financial interest in, or signature authority over, a foreign financial account, or you received a distribution from, were a grantor of, or transferor to a foreign trust.
If none of these apply, you can simply report totals directly on Form 1040 lines 2b (taxable interest) and 3b (ordinary dividends) without attaching Schedule B. Always check the latest IRS guidelines, as thresholds and rules can adjust with tax law changes.
Breaking Down the Parts of Schedule B
Schedule B is straightforward but requires attention to detail. Here’s an overview of each section:
Part I: Taxable Interest
This section lists all sources of taxable interest income. Report amounts from Forms 1099-INT, 1099-OID, or substitute statements. Include interest from U.S. savings bonds, accrued market discount, and gains on contingent payment debt instruments treated as interest.
- Key Exclusions: Do not include tax-exempt interest (e.g., from municipal bonds) here—report it on Form 1040 line 2a instead.
- Special Cases: For seller-financed mortgages, provide the buyer’s name, address, and SSN. Nominee interest requires subtotaling and adjustments.
The total from Part I flows to Form 1040 line 2b.
Part II: Ordinary Dividends
Similar to Part I, list ordinary dividends from box 1a of Forms 1099-DIV. Handle nominee dividends by subtotaling and subtracting amounts distributed to others.
- Note for Foreign Investments: If you owned 10% or more of a foreign corporation, you may need to file Form 5471 separately.
The total goes to Form 1040 line 3b.
Part III: Foreign Accounts and Trusts
This part consists of yes/no questions about foreign financial interests.
- Line 7a: Check “Yes” if you had a foreign account or signature authority. You may also need to file FinCEN Form 114 (FBAR) if aggregate values exceeded $10,000.
- Line 7b: List foreign countries if FBAR is required.
- Line 8: Disclose distributions from or involvement with foreign trusts, which may require Form 3520 or 3520-A.
Failure to report can lead to significant penalties, including up to $10,000 for non-willful FBAR violations.

Common Mistakes to Avoid When Filing Schedule B
- Forgetting Nominee Adjustments: Always subtract nominee amounts to avoid double-taxation.
- Missing Foreign Reporting: Even if no income, disclose foreign accounts to avoid penalties.
- Confusing Tax-Exempt vs. Taxable Interest: Report exempt interest on Form 1040 but not on Schedule B.
- Incomplete Payer Details: For seller-financed mortgages, include all required buyer information to dodge $50 penalties.
- Overlooking Updates: Check for 2025-specific changes, like those in the One Big Beautiful Bill, which extended certain tax cuts but didn’t alter Schedule B directly.
