Schedule B (Form 1040) is a supplemental tax form used to report detailed information about interest income and ordinary dividends you earned during the tax year. Think of it as an itemized breakdown that supports the income numbers you report on your main Form 1040.

The form serves three main purposes. First, it requires you to list each source of interest and dividend income separately when these amounts exceed certain thresholds. Second, it asks important questions about foreign financial accounts, which helps the IRS enforce international tax compliance. Third, it captures special situations like nominee distributions (when you received income that actually belongs to someone else) and seller-financed mortgages.

Schedule B has three parts: Part I covers interest income from banks, bonds, savings accounts, and similar sources; Part II covers ordinary dividends from stocks and mutual funds; and Part III deals with foreign accounts and trusts, including questions about whether you need to file additional forms like FinCEN Form 114 (commonly called the FBAR).

This form is relatively straightforward for most taxpayers, but it's critical to complete it accurately, especially Part III, because mistakes involving foreign accounts can trigger significant penalties.

When You’d Use Schedule B (Filing Deadlines, Late Filing, and Amended Returns)

Regular Filing Deadline

For tax year 2023, Schedule B must be filed along with your Form 1040 by April 15, 2024 (or the next business day if that falls on a weekend or holiday). If you requested an extension, your deadline extends to October 15, 2024. Schedule B is attached to and filed simultaneously with your Form 1040—you cannot file it separately.

Do You Actually Need to File Schedule B?

You must file Schedule B if any of these situations apply:

• Your taxable interest or ordinary dividends exceeded $1,500 during 2023
• 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 purchase
• You're adjusting original issue discount (OID) or amortizable bond premium amounts
• You're claiming the exclusion for U.S. savings bond interest (Series EE or I bonds issued after 1989)
• You received interest or dividends as a nominee for someone else
• You had a financial interest in or signature authority over a foreign financial account, or received a distribution from a foreign trust

If your interest and dividends totaled $1,500 or less and none of the other circumstances apply, you can skip Schedule B and report those amounts directly on Form 1040.

Late Filing and Amended Returns

If you discover you should have filed Schedule B but didn't, you'll need to file an amended return using Form 1040-X. The deadline for amending your 2023 return is generally three years from the date you filed your original return or two years from when you paid the tax, whichever is later. For most 2023 returns filed by April 15, 2024, this means you have until April 15, 2027, to amend.

When amending to add or correct Schedule B, prepare a complete, corrected Schedule B and attach it to Form 1040-X. You must mail amended returns—even though regular returns can be e-filed, amendments for years requiring Schedule B changes often must be sent by mail with proper documentation.

Key Rules or Details for 2023

The $1,500 Threshold

The most important number to remember is $1,500. This is the combined total of your taxable interest and ordinary dividends. If you had $800 in interest and $900 in dividends, that's $1,700 total, so you must file Schedule B. However, if you had $700 in interest and $600 in dividends ($1,300 total), Schedule B generally isn't required unless one of the other special circumstances applies.

What Counts as Taxable Interest

Taxable interest includes earnings from savings accounts, checking accounts, certificates of deposit (CDs), U.S. savings bonds (Series EE, H, HH, and I), Treasury bills and notes, corporate bonds, and most other interest-bearing accounts. You'll typically receive Form 1099-INT showing these amounts. The interest must be reported even if you didn't receive a 1099-INT, as long as it's taxable income.

What Tax-Exempt Interest Means

Interest from municipal bonds and certain other government bonds is usually tax-exempt and doesn't get reported on Schedule B. Instead, it goes on line 2a of Form 1040. However, you still must report the amount—it's just not added to your taxable income. This information helps the IRS verify your return and can affect certain other tax calculations.

Ordinary Dividends vs. Qualified Dividends

Schedule B deals only with "ordinary dividends" (shown in box 1a of Form 1099-DIV). Qualified dividends, which receive preferential tax treatment, are reported separately on Form 1040 but don't need itemization on Schedule B. If you received $2,000 in total dividends but $500 were qualified, you'd list the full $2,000 on Schedule B, but your tax calculation would treat the $500 portion more favorably.

Foreign Account Rules

Part III of Schedule B has strict requirements. You must answer "Yes" to question 7a if at any point during 2023 you had a financial interest in or signature authority over any foreign bank account, brokerage account, mutual fund, or similar account—regardless of the account balance. This includes accounts in Canada, Mexico, the United Kingdom, or any other country outside the United States.

If your foreign accounts' combined value exceeded $10,000 at any time during 2023, you must also file FinCEN Form 114 (FBAR) separately with the Financial Crimes Enforcement Network by April 15, 2024 (with an automatic extension to October 15, 2024). This is filed electronically through the BSA E-Filing System, not with your tax return.

2023 Instructions for Schedule B - IRS

Step-by-Step (High Level)

Step 1: Gather Your Documents

Collect all Forms 1099-INT (interest income) and 1099-DIV (dividend income) you received. These typically arrive by January 31 following the tax year. Also gather any documentation for seller-financed mortgages, bond purchases, or foreign accounts.

Step 2: Complete Part I (Interest)

List each payer's name in column one and the amount of interest in column two. If you have a seller-financed mortgage situation, list that first and include the buyer's name, address, and Social Security number. Add up all the interest amounts and enter the total on line 2. This total flows to Schedule 1 (line 2b), which then goes to your Form 1040.

Step 3: Handle Special Interest Situations

If you received interest as a nominee (it really belongs to someone else), list the full amount you received on line 1, then subtract the nominee portion below your subtotal using the label "Nominee Distribution." If you're adjusting for OID, accrued interest, or bond premium, follow similar subtraction procedures, labeling each adjustment clearly.

Step 4: Complete Part II (Ordinary Dividends)

List each payer's name and the amount of ordinary dividends (from box 1a of Form 1099-DIV) on line 5. Total these amounts on line 6. Handle nominee distributions the same way as in Part I if applicable. This total flows to Form 1040, line 3b.

Step 5: Answer Part III (Foreign Accounts)

Question 7a asks two "Yes/No" questions. The first asks whether you had any foreign financial account during 2023. Answer honestly—this includes any account, regardless of size. The second asks whether you're required to file FinCEN Form 114 (if your accounts exceeded $10,000). If you answer "Yes" to the second question, list the country or countries where the accounts are located on line 7b.

Question 8 asks about foreign trusts. Answer "Yes" if you received a distribution from, or were a grantor of or transferor to, a foreign trust during 2023.

Step 6: Attach to Form 1040

Once complete, attach Schedule B to your Form 1040 when you file. If filing electronically, your tax software will integrate Schedule B automatically. If filing by paper, place Schedule B in the proper sequence with your other schedules.

Common Mistakes and How to Avoid Them

Mistake #1: Not Filing When Required

Many taxpayers assume they don't need Schedule B because their bank sent only one 1099-INT. However, if you have multiple accounts across different institutions and they total over $1,500, you must file. Review all your 1099 forms carefully and add up the totals before deciding.

How to avoid it: Create a simple spreadsheet listing every 1099-INT and 1099-DIV you receive. Calculate the total. If it exceeds $1,500, or if any special circumstances apply, file Schedule B.

Mistake #2: Omitting Payers or Amounts

Some taxpayers round numbers or group multiple payers together under generic labels like "various banks." The IRS expects you to list each payer separately with accurate amounts matching your 1099 forms.

How to avoid it: List each payer exactly as it appears on your 1099 form. If you run out of space on the form, attach additional sheets using the same format, clearly labeled with your name and SSN.

Mistake #3: Incorrectly Reporting Nominee Income

When you receive a 1099 that includes someone else's income (common with joint accounts), you must report the full amount, then subtract the portion belonging to others. Failing to report the full amount can trigger an IRS notice.

How to avoid it: Always report the total shown on the 1099, then use the "Nominee Distribution" subtraction method described in the IRS instructions. You must also issue a 1099-INT or 1099-DIV to the actual owner (unless it's your spouse) and file those forms with the IRS.

Mistake #4: Failing to Answer Foreign Account Questions Honestly

Part III questions about foreign accounts are serious. Some taxpayers skip these questions or answer "No" when they actually have foreign accounts, thinking small balances don't matter. All foreign accounts must be disclosed, regardless of size, when answering question 7a.

How to avoid it: If you have any foreign bank account, brokerage account, pension, or other financial account outside the United States, answer "Yes" to question 7a. Consult the FinCEN Form 114 instructions to determine if you must file that form separately. The penalties for non-disclosure can be severe—up to $10,000 for non-willful violations and the greater of $100,000 or 50% of the account balance for willful violations.

Mistake #5: Reporting Tax-Exempt Interest on Schedule B

Municipal bond interest and other tax-exempt interest should not be listed in Part I of Schedule B. These amounts go directly on Form 1040, line 2a.

How to avoid it: Check box 8 of Form 1099-INT for tax-exempt interest. Report those amounts on Form 1040, line 2a, not on Schedule B. Only taxable interest goes on Schedule B.

Mistake #6: Confusing Ordinary and Qualified Dividends

Schedule B requires listing ordinary dividends (box 1a of Form 1099-DIV), not qualified dividends (box 1b). Qualified dividends are reported on Form 1040 directly but don't need itemization.

How to avoid it: Use the amount from box 1a of Form 1099-DIV when completing Schedule B, Part II. The qualified dividend portion will be handled separately on Form 1040.

What Happens After You File

IRS Processing and Matching

Once you file your return with Schedule B attached, the IRS processes it through their automated systems. They match the interest and dividend amounts you reported against the 1099 forms that banks, brokers, and other payers submitted. This matching process typically occurs within several months of filing.

If there's a discrepancy—for example, you reported $1,200 in interest but the IRS records show $1,500—you'll receive a CP2000 notice (a "matching notice") proposing changes to your return and potentially assessing additional tax, interest, and penalties. You'll have the opportunity to respond and explain the discrepancy or agree with the proposed changes.

Foreign Account Compliance

If you indicated you have foreign accounts in Part III, your return is flagged for potential additional review. The IRS cross-checks whether you filed the required FinCEN Form 114 (if applicable) and Form 8938 (Statement of Specified Foreign Financial Assets, which has different thresholds). Failure to file required foreign account reports can result in substantial penalties, separate from any tax owed.

Nominee Reporting Follow-Up

If you reported nominee distributions, the IRS expects to see corresponding 1099 forms filed by you to document the income you distributed to the actual owners. Failure to file these forms can result in penalties of $50 to $290 per form (as of 2023), depending on how late they are.

Refund or Payment Processing

Schedule B itself doesn't change whether you get a refund or owe money—it simply provides detail supporting the interest and dividend amounts on your Form 1040. Your refund or payment amount is determined by your complete return. If you're due a refund, expect it within 21 days of e-filing or six to eight weeks for paper returns. If you owe money, your payment is due by the filing deadline (April 15, 2024, for most 2023 returns).

Retention for Future Reference

Keep your completed Schedule B and all supporting 1099 forms for at least three years from the date you filed your return, or two years from when you paid any tax due, whichever is later. The IRS recommends keeping records for seven years if circumstances warrant longer retention. These documents will be essential if you need to amend your return or respond to IRS inquiries.

FAQs

1. Do I need Schedule B if I only earned $200 in interest and $1,400 in dividends?

Yes. While each amount individually is below $1,500, the combined total is $1,600, which exceeds the $1,500 threshold. You must file Schedule B when your combined taxable interest and ordinary dividends total more than $1,500, even if each category is individually under the limit.

2. What's the difference between Schedule B and Schedule D?

Schedule B reports interest income and ordinary dividends—the regular income your investments generate. Schedule D reports capital gains and losses—the profit or loss when you sell investments. If you earned $500 in dividends from stock you held (Schedule B) and then sold that stock for a $2,000 gain (Schedule D), both schedules might be required, but they report different types of income.

3. I have a joint bank account with my adult child. Do I report all the interest, even though half belongs to them?

Yes, if the account lists you first or the 1099-INT came in your name, you report the full amount on Schedule B. Then subtract your child's half using the "Nominee Distribution" method. You must also issue your child a Form 1099-INT for their portion (unless special exceptions apply) and file it with the IRS. Your child reports their half on their own return.

4. What if I forgot to report a foreign bank account on Schedule B from a prior year?

This is serious and should be addressed immediately. Consider consulting a tax professional to evaluate your options, which may include filing amended returns or participating in IRS voluntary disclosure programs. Penalties for non-disclosure of foreign accounts can be substantial, but taking corrective action is far better than waiting for the IRS to discover the omission.

5. My broker's 1099-DIV shows qualified dividends. Do I list those on Schedule B?

You list the ordinary dividends amount (box 1a of Form 1099-DIV) on Schedule B, Part II. Box 1a includes all dividends, both qualified and non-qualified. The qualified dividend portion (box 1b) is reported separately on Form 1040 for tax calculation purposes, but the full ordinary dividend amount goes on Schedule B if you're required to file it.

6. Can I e-file Schedule B, or must I mail it?

You can e-file Schedule B along with your Form 1040. Most tax preparation software automatically includes Schedule B when needed. However, if you're filing Form 1040-X to amend a return and add or correct Schedule B, some amendments must be mailed with paper documentation, depending on the circumstances and the tax year involved.

7. What happens if I check "No" on the foreign account question but I actually have a foreign account?

Incorrectly answering the foreign account questions can result in severe penalties, particularly if the IRS determines the failure was willful. Non-willful violations can carry penalties up to $10,000, while willful violations can result in penalties of $100,000 or 50% of the account balance, whichever is greater, plus potential criminal penalties. If you realize you made a mistake, consult a tax professional immediately about corrective actions, which may include filing amended returns and delinquent foreign account reports through appropriate IRS procedures.
