IRS Schedule B: Who Has to File It and How to Fill It Out

IRS Schedule B (Form 1040), "Interest and Ordinary Dividends," is the attachment where you list the payers of your taxable interest and ordinary dividends and answer questions about foreign accounts and trusts. You generally have to file it when your taxable interest or your ordinary dividends are more than $1,500, or when one of a few other situations applies.

Here's the short version of how it works, what each part asks for, and the parts people tend to get wrong.

Who has to file Schedule B?

You generally file Schedule B with your Form 1040 if any of the following is true:

Your taxable interest was over $1,500.
Your ordinary dividends were over $1,500.
You received interest from a seller-financed mortgage and the buyer used the property as a home.
You have accrued interest from a bond you bought between interest payment dates.
You're reporting original issue discount (OID) adjustments, or excluding interest from series EE or I U.S. savings bonds issued after 1989 (Form 8815).
You received interest or dividends as a nominee, meaning the income really belongs to someone else.
You had a foreign financial account or were a grantor of, or transferor to, a foreign trust.

Under $1,500 and none of the above? You still report the income on your return. You just don't need the schedule. The thresholds and instructions can change, so check the current Schedule B instructions for the tax year you're filing.

What goes on Part I (interest)?

Part I lists each payer and the amount of taxable interest, using the figures from your Form 1099-INT, Form 1099-OID, or brokerage statement. Banks, credit unions, brokerages, and the lender on a seller-financed note are all typical payers.

The flow is short:

Line 1: list each payer and amount.
Line 2: add the amounts.
Line 3: subtract any excludable savings bond interest from Form 8815.
Line 4: the result, which carries to Form 1040, line 2b.

Tax-exempt interest, such as municipal bond interest, isn't included here. It goes on a separate line of the 1040 for information.

What goes on Part II (ordinary dividends)?

Part II works the same way for dividends. List each payer from your Form 1099-DIV (line 5), total them (line 6), and carry that figure to Form 1040, line 3b.

Ordinary dividends are the amounts in box 1a of Form 1099-DIV. Qualified dividends, which can be taxed at lower rates, are a subset of that number and are reported separately on the 1040. Capital gain distributions go on a different part of the return and aren't totaled on Schedule B.

If you sold investments during the year, those sales are reported elsewhere. For how the state treats them, see California capital gains tax.

What is Part III (foreign accounts and trusts)?

Part III asks yes-or-no questions. Anyone filing Schedule B has to complete it, and you can end up filing Schedule B for this part alone even when your interest and dividends are small.

Line 7a asks whether you had a financial interest in, or signature authority over, a financial account located in a foreign country. If yes, you also answer whether you're required to file FinCEN Form 114 (the FBAR). That filing generally applies when the combined value of your foreign accounts went over $10,000 at any point in the year.
Line 7b asks which countries the accounts are in.
Line 8 asks whether you received a distribution from, or were a grantor of or transferor to, a foreign trust. A yes can bring in Form 3520.

Schedule B is not a substitute for those other filings. If you hold foreign assets, Form 8938 has its own thresholds and is separate from the FBAR. If you paid tax to another country, Form 1116 is where the foreign tax credit is claimed. Penalties for missing foreign reporting can be steep, so it's worth getting this part right.

How is Schedule B different from Schedule A?

They have nothing in common except the alphabet. Schedule A is for itemized deductions (mortgage interest, state and local taxes, charitable gifts). Schedule B reports investment income. A search for "IRS Schedule A and B" usually means someone has both attached to a return, which is common for people who itemize and also hold savings or brokerage accounts.

What mistakes come up most often?

Leaving out small amounts. The IRS receives the same 1099s you do. Interest under $10 may not generate a form, but it's still reportable income.
Skipping nominee income. If a 1099 shows income that belongs to someone else, you list the full amount, then subtract the portion that isn't yours and label it "Nominee Distribution."
Answering Part III from memory. A forgotten overseas account is a bigger problem than a small interest total.
Missing a late-arriving 1099. Brokerage firms sometimes issue corrected forms in February or March. If one arrives after you file, you may need to amend. See Form 1040-X.

What if you own a business or rental property?

Schedule B covers passive investment income like savings interest and dividends. Business income goes on Schedule C, and rental income goes on Schedule E. If you're an S-corp owner holding cash or investments in the business, how that income is reported depends on the entity, so it's worth a conversation with someone who handles S-corp and business tax returns.

Interest and dividends can also push your quarterly payments up. If your investment income is significant, see quarterly estimated taxes for the self-employed so a surprise balance doesn't catch you in April.

What's the next step?

Gather every Form 1099-INT, 1099-DIV, and 1099-OID, plus a list of any foreign accounts, before you start. Total each part, check the $1,500 thresholds, and answer Part III. If your situation involves foreign accounts, nominee income, or a large investment portfolio, tax planning before year-end is easier than cleanup after.

Frequently asked questions

Do I have to file Schedule B if I earned less than $1,500 in interest?

Generally no, unless another trigger applies, such as nominee income, a seller-financed mortgage, Form 8815 savings bond exclusions, or a foreign account or trust. You still report the interest on your Form 1040.

Where does Schedule B go on my return?

Schedule B attaches to Form 1040. The totals carry to line 2b (taxable interest) and line 3b (ordinary dividends).

Is Schedule B the same as Schedule 1?

No. Schedule 1 reports additional income and adjustments to income, such as business income and certain deductions. Schedule B is specifically for interest, ordinary dividends, and foreign account questions.

Do I need Schedule B for a high-yield savings account?

Only if the taxable interest is more than $1,500 or another filing trigger applies. The interest is taxable income either way, and the bank reports it on Form 1099-INT.

What if I forgot to file Schedule B?

If you should have filed it, you can usually correct it by amending with Form 1040-X. If you've received an IRS notice, see our page on IRS tax problem help.
