What is Schedule B?
Schedule B, Interest and Ordinary Dividends, attaches to Form 1040 whenever taxable interest or ordinary dividends exceed $1,500 (each tested separately). It's an itemized list: every payer and amount from your 1099-INT and 1099-DIV forms, totaled onto your 1040.
Part III is the part people underestimate: it asks whether you had a financial interest in or signature authority over foreign financial accounts. Answering it accurately — and filing the separate FBAR when foreign accounts top $10,000 — carries some of the steepest penalties in the tax code for getting it wrong.
Who files Schedule B?
- Savers — high-yield savings, CDs, and Treasury interest add up past $1,500 quickly at modern rates.
- Dividend investors with over $1,500 of ordinary dividends across brokerage accounts.
- Anyone with foreign accounts — Part III applies even when interest is under $1,500.
- Recipients of seller-financed mortgage interest and accrued bond interest, which have special lines.
Deadlines
Files with Form 1040 by the April deadline. If Part III applies, the separate FBAR (FinCEN Form 114) is also due in April (auto-extended to October) — it files with FinCEN online, not with your tax return.
How to fill out Schedule B
Collect 1099-INT and 1099-DIV forms
Banks and brokers must issue them for $10+ of interest or dividends — but you must report interest even when no 1099 arrives.
Part I — list interest by payer
Each bank or payer on its own line with the amount; subtotal carries to Form 1040.
Part II — list ordinary dividends by payer
From box 1a of each 1099-DIV. Qualified dividends (box 1b) also go on the 1040 for their lower rate.
Part III — answer the foreign account questions
Every filer completing Schedule B must answer. "Yes" answers may trigger FBAR and Form 8938 filing.
