Learn when Schedule B is required, how interest and ordinary dividends are listed, what foreign-account questions mean, and how California may differ.
Schedule B is the federal schedule used with Form 1040 or Form 1040-SR to list taxable interest and ordinary dividends and to answer questions about certain foreign financial accounts and foreign trusts.
For 2025, having more than $1,500 of taxable interest or ordinary dividends is a common filing trigger, but it is not the only one. The Schedule B instructions list additional situations involving seller-financed mortgages, bond adjustments, nominee income, foreign accounts, and foreign trusts.
Part I generally lists each payer of taxable interest and the amount. Common source documents include:
Taxable interest can exist even when no Form 1099 is issued. Conversely, an information return may require an adjustment when the taxpayer is a nominee, purchased a bond between interest dates, has amortizable bond premium, or reports original issue discount differently under the rules.
Tax-exempt interest is generally reported on Form 1040 rather than included as taxable interest on Schedule B, but it still must be identified and may affect other calculations.
Part II lists payers of ordinary dividends. Form 1099-DIV box 1a generally reports total ordinary dividends, while box 1b identifies the portion that may be qualified dividends.
Qualified dividends are not a separate Schedule B income category. They are included within ordinary dividends, then separately identified on Form 1040 so the applicable qualified-dividend and capital-gain tax computation can be used.
Capital-gain distributions are also not ordinary dividends for Schedule B. They generally follow the Form 1040 and Schedule D instructions.
The 2025 instructions identify several triggers, including when:
The exact instructions should be checked each year. Receiving a single Form 1099-INT does not automatically require Schedule B if no other trigger applies, but the income may still need to be reported on Form 1040.
Maria receives:
| Source | Amount | General treatment |
|---|---|---|
| Bank interest | $900 | Taxable interest |
| Treasury interest | $700 | Federally taxable interest |
| Ordinary dividends | $1,200 | Ordinary dividends |
| Qualified-dividend portion | $800 | Included in the $1,200, separately identified |
Her taxable interest is $1,600, so the over-$1,500 interest trigger applies. Schedule B lists the interest payers and total. Her $1,200 of ordinary dividends is listed in Part II as required by the return instructions. The $800 qualified portion is not added again; double counting it would overstate income.
For California, U.S. Treasury interest generally receives a state subtraction through Schedule CA, while interest from another state's municipal bonds may require a California addition. The source and issuer matter.
Schedule B Part III asks whether the taxpayer had a financial interest in or signature authority over a foreign financial account and whether the taxpayer had certain foreign-trust involvement. Answering "yes" may lead to separate reporting, including FinCEN Form 114, Form 8938, or a foreign-trust information return.
These forms have different definitions, thresholds, filing systems, and deadlines. Filing Schedule B does not replace them. Penalties can be significant, so a taxpayer should not answer based only on whether the account produced taxable income.
Cryptocurrency held through a foreign platform, online payment accounts, inherited foreign accounts, and employer signature authority require fact-specific review.
A taxpayer is a nominee when an information return reports income under that taxpayer's identifying number but some or all of the income actually belongs to another person. The Schedule B instructions may require the taxpayer to list the full amount and a nominee adjustment, and information-return filing duties may apply.
Do not simply omit the amount or move it to another person's return. Keep ownership records and follow the nominee-reporting instructions.
| Item | Typical federal location |
|---|---|
| Taxable interest and ordinary dividends | Schedule B when required |
| Capital gains and losses | Schedule D and Form 8949 when required |
| Business interest income | Schedule C when earned in the business |
| Partnership or S corporation items | Schedule E and Schedule K-1 workflow |
| Investment-interest deduction | Schedule A and possibly Form 4952 |
California generally starts with federal income but may adjust interest and dividends on Schedule CA (540) or Schedule CA (540NR). Common differences include:
Schedule B itself is a federal schedule. It does not calculate California additions or subtractions. See California residency rules for how investment income is sourced and taxed at the state level.
Retain Forms 1099-INT, 1099-OID, and 1099-DIV; complete brokerage statements; account ownership records; bond purchase confirmations; accrued-interest and premium schedules; seller-financed mortgage documents; foreign-account statements; maximum balance information; foreign-trust documents; and prior-year carryover workpapers.
Reconcile every payer, account number, and amount. Corrected information returns can arrive after the original statement.
Heath Income Tax can reconcile interest and dividend statements, identify California adjustments, and coordinate Schedule B with investment, nominee, and foreign-account reporting.
Do I need Schedule B for $100 of bank interest?
Possibly not based on amount alone, but another Schedule B trigger could apply. The $100 must still be reported when taxable.
Are qualified dividends reported on Schedule B?
They are included in ordinary dividends and separately identified on Form 1040 for the tax-rate calculation. They are not added twice.
Is municipal-bond interest always tax-free?
No. Federal and California treatment depends on the issuer and type of obligation. Tax-exempt interest can also affect other tax calculations.
Does a foreign account with no interest require review?
Yes. Foreign-account reporting can depend on ownership, authority, and balance — not only income.
