Here’s a situation we see all the time: You open a joint account to help manage an aging parent's finances or split interest with a partner for estate planning purposes.
Then the 1099-INT arrives in January… and it reports 100% of the interest income under your Social Security Number—even though most of that money wasn’t really yours.
Sound familiar? Welcome to the complicated world of nominee interest accounts.
If you don't report things the right way, the IRS may think you're underreporting income. But don’t panic. With the right forms—and a little know-how—you can correct it smoothly and stay penalty-free.

What Is a Nominee Interest Account?
A nominee interest account is one where the interest income shows up under your name or SSN—but the money actually belongs to someone else (at least in part).
It happens all the time: family CDs, joint savings accounts, even custodial setups where a parent helps manage a minor's funds.
Think of yourself as the “middleman” on paper—responsible for forwarding the tax data to the rightful owner.
Why the IRS Cares About Nominee Reporting
The IRS doesn't manually read every return—they use matching software. If your tax return shows $500 of interest but your 1099-INT shows $1,500, the computer assumes you're shortchanging Uncle Sam.
Even if the difference belongs to your spouse, child, or parent, you can still get flagged—unless you correct it with proper nominee forms.
It’s not fraud—it’s family. But you need to speak IRS’s language to explain that.
When You Must File a 1099-INT as a Nominee
Simple rule: If you receive a 1099-INT showing interest that isn’t 100% yours, and that interest totals more than $10 for another party, you are legally required to issue a nominee 1099-INT.
That means:
- Sending a 1099-INT to the actual income recipient
- Filing Form 1096 to transmit the copy to the IRS
And yes, you’re acting like a mini-financial institution in the eyes of the IRS. Welcome to the club.
π‘ Not sure if this rule even applies to you? This simple 1-minute flowchart helps determine if nominee filing is required:
How to Properly Split and Report Interest Income
Let’s say the bank sent you a 1099-INT for $1,200. But in reality, only $400 of that interest is yours. The other $800? That belongs to Mom.
Here’s what to do:
- Report the full $1,200 on your Schedule B
- Deduct the $800 as a “nominee distribution”
- Issue your own 1099-INT to your mom for $800
- Transmit it with Form 1096 to the IRS
Sounds bureaucratic? It is. But if you skip these steps, you could pay tax on someone else’s earnings—literally.
Step-by-Step: Filling Out 1099-INT and 1096
Form 1099-INT
- Payer: You (the nominee)
- Recipient: The actual income owner
- Box 1: Total interest they earned
Form 1096
- One cover sheet per paper-filed group of 1099s
- Submit to IRS with physical copy (or e-file separately)
You’re essentially acting as a reporting agent for this small transaction. It’s like becoming a one-person bank, just for tax season.
Common Scenarios: Joint Accounts, Custodians, Minor Accounts
✅ Joint accounts: The IRS doesn’t care whose name is listed first—it wants to know who earned the income.
✅ Custodial accounts (e.g., UTMA/UGMA): If interest belongs to a minor, don’t let it sit on your tax return.
✅ Accounts for elderly parents: Co-signing for access doesn’t make the interest yours. It just gives you reporting headaches if ignored.
If the income isn’t yours, don’t claim it—but do explain it.
Penalties for Noncompliance (And How to Avoid Them)
Missing nominee 1099s can trigger penalties of $60–$310 per form. That’s per recipient, per year.
Worse? The IRS could treat the missing forms as underreporting and apply failure-to-file penalties or initiate an audit.
It’s like skipping your dentist appointment—you might get away with it once, but the pain later isn’t worth it.
FAQ: What If It’s Under $10? What If It’s a Trust?
πΉ Under $10? No 1099 is required, but you still need to allocate the income properly on your return.
πΉ Trust or estate? Consult a CPA. These often require separate filings, such as Forms 1041 or K-1, depending on structure.
Think of it this way: If the IRS sees your SSN on income that isn’t yours, and you don’t explain it—they’ll assume it is.
