Schedule B remains one of the most commonly required IRS forms for taxpayers with interest and dividend income. For the 2025 tax year, the form hasn’t changed dramatically, but the rules around who must file it—and how to report foreign accounts—continue to trip up many filers. Understanding Schedule B is essential if you earn interest, receive dividends, or hold money in foreign financial institutions. This guide breaks down everything you need to know for 2025.
What Is Schedule B?
Schedule B (Form 1040) is an attachment used to report interest and ordinary dividend income. It also asks important questions about foreign bank accounts, foreign trusts, and financial assets. While many taxpayers earn some interest or dividends, not everyone needs Schedule B. The form is required only when your income or financial situation meets specific IRS thresholds.
For 2025, Schedule B continues to serve three main purposes:
- Reporting taxable interest income over certain limits
- Reporting ordinary dividends over certain limits
- Disclosing foreign financial accounts and foreign trust involvement
Who Must File This Form
You must file Schedule B with your 2025 Form 1040 if any of the following apply:
1. You Have More Than $1,500 in Taxable Interest or Dividends
If your combined interest or dividend income exceeds $1,500, Schedule B is mandatory. This includes income from:
- Banks and credit unions
- Brokerage accounts
- Certificates of deposit (CDs)
- Treasury securities
- Money market accounts
- Mutual funds
Even if you receive multiple 1099‑INT or 1099‑DIV forms, you only need Schedule B if the total crosses the $1,500 threshold.
2. You Received Interest From a Seller‑Financed Mortgage
If you sold property and financed the loan yourself, you must report the buyer’s name, address, and Social Security number on Schedule B.
3. You Have Foreign Bank Accounts
Schedule B asks whether you had a financial interest in or signature authority over a foreign bank account. If the total value of your foreign accounts exceeded $10,000 at any time in 2025, you must also file an FBAR (FinCEN Form 114).
4. You Received Distributions From a Foreign Trust
If you were a grantor or beneficiary of a foreign trust, Schedule B requires you to disclose it. You may also need to file Form 3520 or Form 3520‑A.
What Income Goes on Schedule B?
Schedule B is divided into three parts, each covering a different type of information.
Part I: Interest Income
You must list all taxable interest, including:
- Bank interest
- Brokerage interest
- Interest from U.S. Treasury bonds
- Interest from savings bonds
- Interest from seller‑financed mortgages
Tax‑exempt interest does not go on Schedule B, but it must still be reported elsewhere on Form 1040.
Part II: Ordinary Dividends
This section covers:
- Ordinary dividends from stocks
- Mutual fund distributions
- REIT dividends
- Dividends from foreign corporations
Qualified dividends are still reported on Form 1040, but Schedule B helps the IRS verify the total.
Part III: Foreign Accounts and Trusts
This section asks:
- Did you have a foreign bank account?
- Did the total value exceed $10,000?
- Are you required to file an FBAR?
- Did you receive a distribution from a foreign trust?
Answering these questions accurately is critical. The IRS imposes severe penalties for failing to disclose foreign accounts.
Common Mistakes to Avoid on Schedule B
Many taxpayers make avoidable errors when completing Schedule B. For 2025, keep an eye out for these common issues:
1. Forgetting Small Interest Accounts
Even a few dollars of interest from a savings account must be included. Banks may not issue a 1099‑INT if interest is under $10, but you still must report it.
2. Mixing Up Ordinary and Qualified Dividends
Ordinary dividends go on Schedule B. Qualified dividends receive special tax treatment and are reported separately on Form 1040.
3. Not Reporting Foreign Accounts
Even if the account earned no interest, you must still answer the foreign account questions truthfully.
4. Missing Seller‑Financed Mortgage Details
If you financed a home sale, the IRS requires the buyer’s information. Leaving this blank can trigger a notice.
How to File Schedule B for 2025
Filing Schedule B is straightforward once you gather your documents. Here’s what you’ll need:
- All 1099‑INT forms
- All 1099‑DIV forms
- Records of foreign accounts
- Details of any seller‑financed mortgages
- Information about foreign trusts
Most tax software automatically generates Schedule B when your income requires it. If you file manually, attach Schedule B to your Form 1040 and ensure all totals match your supporting documents.
Why Schedule B Matters
The IRS uses Schedule B to verify income that is often under-reported. With interest rates still elevated in 2025, more taxpayers are earning higher interest from savings accounts, CDs, and Treasury securities. That means more people will cross the $1,500 threshold and need Schedule B.
Additionally, global banking and investment platforms have made foreign accounts more common. The IRS continues to prioritize foreign account compliance, making Schedule B disclosures more important than ever.
Final Thoughts
Schedule B for 2025 is a crucial form for taxpayers with interest, dividends, or foreign financial accounts. Filing it correctly ensures compliance, avoids penalties, and keeps your tax return accurate. Whether you’re earning more interest due to higher rates or investing internationally, understanding Schedule B helps you stay ahead of IRS requirements and file with confidence.
