Schedule B (Form 1040) is a supplementary tax form that helps you report interest and ordinary dividend income you earned during the tax year. Think of it as the detailed backup documentation for the interest and dividend amounts you list on your main Form 1040 tax return.

This form serves three primary purposes. First, it provides a comprehensive list of all the banks, brokerage firms, and other entities that paid you interest or dividends. Second, it helps you calculate your total taxable interest and ordinary dividend income. Third, it includes important questions about foreign financial accounts and trusts that the IRS uses to ensure compliance with international tax reporting requirements.

Most taxpayers don't need Schedule B—you only file it in specific circumstances. The most common trigger is receiving more than $1,500 in combined taxable interest and ordinary dividends during the year. Even if your investment income falls below this threshold, you'll still need Schedule B if you have certain types of interest income, such as interest from a seller-financed mortgage where the buyer uses the property as their home, or if you're adjusting your reported income for reasons like bond premium amortization or claiming exclusions for U.S. savings bond interest used for education expenses.

Additionally, Schedule B plays a critical role in foreign account reporting. If you had any financial interest in or authority over foreign bank accounts, investment accounts, or if you dealt with foreign trusts, you must complete Part III of this form regardless of your income level. This helps the IRS track worldwide income and enforce compliance with laws designed to prevent offshore tax evasion. IRS.gov

When You’d Use Schedule B (Including Late and Amended Returns)

Original Filing and Due Dates

You'll file Schedule B alongside your regular Form 1040 when you originally file your tax return for 2024—typically by April 15, 2025 (or October 15, 2025, if you file for an extension). The schedule attaches directly to your 1040 and is due on the same date.

Amended Returns and Corrections

However, life happens, and you might discover after filing that you forgot to report some interest income or made errors on your original Schedule B. In these situations, you'll need to file an amended return using Form 1040-X (Amended U.S. Individual Income Tax Return). You generally have three years from the date you filed your original return, or two years from the date you paid the tax (whichever is later), to file an amended return and claim a refund.

When filing an amended return that includes Schedule B corrections, you'll prepare a new, corrected Schedule B and write "Amended" at the top. Attach this revised schedule to your Form 1040-X along with any supporting documentation such as missing 1099-INT or 1099-DIV forms that explain the changes. Since 2020, you can file amended returns electronically for the current and two prior tax years, which speeds up processing considerably compared to paper filing. IRS.gov

Corrected Forms After Filing

You might also receive a corrected 1099 form after you've already filed—financial institutions have until mid-February to issue these forms, and sometimes they send corrections later. If the correction changes your tax liability significantly or triggers the need for Schedule B (by pushing you over the $1,500 threshold), file an amended return promptly to avoid potential penalties and interest charges.

Key Rules or Details for 2024

The $1,500 Threshold

The $1,500 threshold is the cornerstone rule for Schedule B. If your combined taxable interest and ordinary dividends total $1,500 or less, you simply report these amounts directly on Form 1040 lines 2b and 3b without needing Schedule B. Once you cross that $1,500 mark, the IRS wants to see the detailed breakdown.

Other Situations That Require Schedule B

Several other situations mandate Schedule B filing regardless of the dollar amount. These include receiving interest from a seller-financed mortgage (where you must also report the buyer's Social Security number and address), reporting accrued interest from bonds, claiming the education savings bond interest exclusion (Series EE or I bonds issued after 1989), adjusting original issue discount (OID) amounts, reducing interest income due to amortizable bond premium, or receiving interest or dividends as a nominee (meaning the income legally belongs to someone else but came to you first).

Foreign Account Reporting Requirements

The foreign account reporting requirements in Part III are particularly important for 2024. You must answer the foreign account questions if any of these apply: you had over $1,500 of taxable interest or ordinary dividends, you had a financial interest in or signature authority over any foreign financial account at any time during 2024, or you received a distribution from or were a grantor/transferor to a foreign trust.

Penalties and Related Forms

The stakes are high for foreign account non-compliance. If you're required to file FinCEN Form 114 (commonly called FBAR) and fail to do so, civil penalties can reach $10,000 per violation for non-willful failures. Willful violations carry penalties up to the greater of $100,000 or 50% of the account balance, plus potential criminal charges. You may also need to file Form 8938 (Statement of Specified Foreign Financial Assets) with your tax return, which has its own penalties and extends the statute of limitations for IRS audits. IRS.gov

Step-by-Step (High Level)

Step 1: Gather Your Documents

Collect all Forms 1099-INT (interest income), 1099-OID (original issue discount), and 1099-DIV (dividend income) from banks, brokerages, and other payers. These typically arrive by January 31 following the tax year. If you receive consolidated statements from brokerage firms, you can list the firm's name once with the total amount rather than listing each individual security.

Step 2: Complete Part I – Interest

List each payer's name and the amount of interest received. If you received interest from a seller-financed mortgage where the buyer used the property as a personal residence, list this first and include the buyer's Social Security number and address. Add all interest amounts to get your subtotal. If you received interest as a nominee (belonging to someone else), subtract the nominee amount. Make any other adjustments for excludable savings bond interest, accrued interest, or bond premium. Enter your final taxable interest amount on line 4, which transfers to Form 1040 line 2b.

Step 3: Complete Part II – Ordinary Dividends

Follow the same process for dividends. List each payer and amount, add them up, make any nominee adjustments, and enter the total on line 6. This amount transfers to Form 1040 line 3b. Note that qualified dividends (which receive preferential tax rates) go directly on Form 1040 and aren't separately calculated on Schedule B.

Step 4: Complete Part III – Foreign Accounts and Trusts

You must complete this part if your interest or dividends exceeded $1,500, or if you had any involvement with foreign accounts or trusts. Answer whether you had financial interest in or signature authority over any foreign account. If yes, indicate whether you're required to file FinCEN Form 114 and list the countries where accounts are located. Answer the foreign trust question and understand that "Yes" responses typically require filing additional forms (Form 3520 or 3520-A) separately from your tax return.

Step 5: Attach and File

Attach the completed Schedule B to your Form 1040 or 1040-SR. File everything together by the April 15 deadline (or October 15 if extended). Remember that certain foreign reporting forms have different due dates and filing addresses. IRS.gov

Common Mistakes and How to Avoid Them

Missing 1099 Forms

One of the most frequent errors is forgetting to include all sources of interest and dividends. If you have accounts at multiple institutions or moved money during the year, you might receive 1099s you weren't expecting. Cross-check your records carefully and wait until mid-February before filing to ensure you've received all forms. Remember that financial institutions report these amounts directly to the IRS, so they'll catch any omissions through computer matching.

Nominee Reporting Errors

If you received interest or dividends that legally belong to someone else (like a joint account where you're listed but your parent actually owns the funds), you must report the full amount and then subtract the nominee distribution. Many taxpayers simply don't report these amounts at all, which triggers IRS notices. Additionally, if you receive income as a nominee, you're required to issue a Form 1099 to the actual owner (unless it's your spouse) and file it with the IRS.

Foreign Account Non-Disclosure

Failing to answer Part III questions or checking "No" when you actually had foreign accounts is a serious mistake with severe penalties. "Foreign account" means any account physically located outside the United States, regardless of whether the bank has a U.S. branch. Even small foreign accounts count, and signature authority (like being authorized to sign on your employer's foreign bank account) requires disclosure even if you don't own the account.

Confusing Ordinary vs. Qualified Dividends

Schedule B only deals with ordinary dividends. Qualified dividends (which qualify for lower capital gains tax rates) are reported on Form 1040 separately. Don't mix these up or double-report amounts. Your 1099-DIV shows both amounts in different boxes—box 1a is ordinary dividends (goes on Schedule B line 5), while box 1b is qualified dividends (goes directly on Form 1040 line 3a).

Forgetting to File When Required

If your total interest and dividends are just above $1,500, some taxpayers mistakenly think they can skip Schedule B. The IRS computers will catch this discrepancy when they match your 1099 forms to your return. Even if you're just slightly over the threshold, you must file the complete Schedule B.

Not Keeping Good Records

Schedule B requires you to list specific payer names and amounts. If you've lost your 1099 forms, you can request duplicates from your financial institutions or access them online through your account portals. Most brokerages and banks maintain online document centers where prior-year forms are available. IRS.gov

What Happens After You File

IRS Processing and Matching

Once you submit your return with Schedule B attached, the IRS processes it through their automated systems, which typically takes 21 days for e-filed returns or up to six weeks for paper returns. The IRS computers automatically match the amounts you reported on Schedule B against the 1099 forms that financial institutions filed with them.

If everything matches and your return is accepted without issues, you'll receive your refund (if applicable) according to the normal timeline. You can check your refund status using the "Where's My Refund?" tool on IRS.gov or through the IRS2Go mobile app.

Notices and Discrepancies

However, if there are discrepancies, you might receive an IRS notice. Common notices related to Schedule B include CP2000 (Underreported Income), which means the IRS has information showing you received more interest or dividends than you reported. These aren't audits but rather automated matching notices. You'll have the opportunity to respond, either agreeing with the proposed changes or explaining the discrepancy (perhaps you already reported the income differently, or the 1099 was incorrect).

Foreign Account Cross-Checks

For foreign account reporting in Part III, checking "Yes" to having foreign accounts triggers additional scrutiny. The IRS may cross-reference your Schedule B answers with separately filed FinCEN Form 114 (FBAR) and Form 8938 to ensure consistency. Serious discrepancies in foreign account reporting can lead to audits and investigations.

Record Retention

Keep your Schedule B and all supporting 1099 forms for at least three years from the date you filed your return (or the due date, whichever is later). The IRS can generally audit returns within three years, though this extends to six years if you substantially underreported income, and indefinitely for fraud. Foreign account issues can trigger the six-year statute of limitations.

Amended Return Processing

If you filed an amended return with a corrected Schedule B, processing takes longer—typically up to 16 weeks or more. You can check the status of your amended return online using the "Where's My Amended Return?" tool on IRS.gov approximately three weeks after mailing it. IRS.gov

FAQs

Q1: Do I need Schedule B if I only have $1,600 in interest and no dividends?

Yes. The $1,500 threshold applies to combined taxable interest and ordinary dividends. Since your interest alone exceeds $1,500, you must file Schedule B even with zero dividends.

Q2: My brokerage sent me one 1099 showing $800 of interest and $900 of dividends from multiple investments. Can I just list the brokerage once?

Absolutely. When you receive a consolidated 1099 from a brokerage firm, list the firm's name as the payer and enter the total interest and total dividends shown. You don't need to break down each individual stock or bond.

Q3: I have a joint bank account with my elderly mother, but all the money is hers. The 1099-INT came in my Social Security number. What do I do?

Report the full interest amount on Schedule B line 1, then on a separate line write "Nominee Distribution" and subtract the amount that belongs to your mother. You must also issue your mother a Form 1099-INT for her share (since she's not your spouse) and file it with the IRS.

Q4: I forgot to report $300 of interest income on my 2024 return I already filed. Should I file an amended return?

While you're technically required to report all income, whether to amend for small amounts is a judgment call. The IRS may or may not catch it through automated matching. If they do, you'll receive a notice with penalties and interest. Many tax professionals recommend amending to avoid potential hassles, especially if the error is substantial enough to change your tax liability. For $300 of interest, your additional tax might only be $50-$100 depending on your tax bracket, but penalties and interest can add up.

Q5: What counts as a "foreign account" for Part III purposes?

Any bank account, brokerage account, or other financial account physically located outside the United States. This includes accounts you own, jointly own, or have signature authority over. The citizenship or location of the bank's headquarters doesn't matter—if the specific account is located overseas, it's foreign. For example, a Canadian bank account is foreign even if the bank has U.S. branches.

Q6: Do I report cryptocurrency interest or staking rewards on Schedule B?

This is an evolving area. Currently, cryptocurrency interest from lending platforms or staking rewards might be reported as ordinary income, but the IRS hasn't definitively classified how these appear on tax forms. Many crypto platforms issue 1099-MISC or 1099-INT forms. If you receive a 1099-INT for crypto interest and it pushes you over $1,500, include it on Schedule B. Consult a tax professional familiar with cryptocurrency taxation for complex situations.

Q7: I answered "Yes" to having a foreign account on Schedule B but forgot to file the FBAR (FinCEN Form 114). What should I do?

File the delinquent FBAR as soon as possible. The IRS has procedures for taxpayers who missed foreign reporting deadlines, including the Delinquent FBAR Submission Procedures for those with reasonable cause. Acting proactively before the IRS contacts you typically results in better outcomes than ignoring the situation. Given the severe penalties involved, consider consulting a tax professional who specializes in international tax compliance.
