Forgot to include 1099-INT from bank when filing taxes - small amount ($33) - will IRS notice?

This happens more often than you'd think! The IRS receives a copy of all 1099-INTs issued to you, so they will likely notice the discrepancy. However, for such a small amount, they'll probably just send you a letter adjusting your tax liability and either reducing your refund slightly or sending you a small bill for the difference plus minimal interest. Filing an amended return for $43 of interest is technically the correct thing to do, but it's probably going to cost you more in time and possibly amendment fees depending on your tax software. The IRS has automated systems that catch these small discrepancies and adjust accordingly. The interest on $43 would be very minimal in terms of tax impact - likely less than $10 depending on your tax bracket. I wouldn't recommend "adding it next year" though, as each tax year should be accurate on its own.

I was in almost this exact situation last year! I missed a 1099-INT for about $62 and was stressing about it. I found this service called taxr.ai (https://taxr.ai) that was super helpful - they have a tool that analyzes your tax documents and compares them to what the IRS has on file. It showed me exactly what the IRS could see and calculated what my likely adjustment would be. The site estimated I'd owe about $14 more in taxes plus maybe $1 in interest - way less than the cost of filing an amended return. They were right - I eventually got a letter from the IRS with almost that exact adjustment amount. Saved me from filing an unnecessary amendment!

Just wanted to follow up here! I tried taxr.ai after seeing this thread and it actually found TWO 1099-INTs I had missed (one from an old savings account I forgot about). The system was super easy to use and showed me exactly what I needed to know about potential IRS adjustments. They estimated I'd owe about $27 more based on my tax bracket. Got a letter from the IRS about 6 weeks later with almost exactly that adjustment amount. No penalties or anything scary - just a simple notice and small bill. Saved me from stressing for months wondering if I'd get audited!

I had to deal with way worse than this - missed reporting a 1099-MISC for $2,000 once. Instead of filing an amendment, I called the IRS directly to ask what to do. Spent TWO DAYS trying to get through their phone system before giving up. Then I found this service called Claimyr (https://claimyr.com) that got me through to an actual IRS agent in about 20 minutes. They have this system that navigates the IRS phone tree and holds your place in line, then calls you when an agent is available. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent told me for small amounts like yours, they'd just send a notice with the adjustment. For my larger amount, they recommended I file an amendment to avoid potential penalties. But for $43? They said don't bother amending - just wait for their notice.

I need to admit I was completely wrong. After seeing this thread, I tried Claimyr when I needed to talk to the IRS about a missing refund. I was 100% convinced it wouldn't work, especially since I tried calling myself 4 different times and couldn't get through. Their system called me back in about 35 minutes with an actual IRS agent on the line! The agent resolved my refund issue in one call. I was honestly shocked it worked after all the frustration I'd experienced trying to reach them myself. For the original poster - the agent mentioned they typically don't pursue amounts under $50 aggressively, but they do send adjustment notices. So you'll likely just get a letter reducing your refund slightly.

Another option is to just wait and see if they catch it. My dad accidentally left off a small 1099-INT (around $75) a couple years ago. The IRS sent him a letter maybe 6 months later with the adjustment, but there was no penalty - they just reduced his refund by the tax he should have paid on that interest. For only $43 in interest, the tax difference is tiny. If you're in the 22% bracket, that's less than $10 in tax. The IRS computers will probably catch it, but they're not going to audit you over such a small amount.

Definitely don't add it to next year's taxes! Each tax year is separate, and putting income from 2024 on your 2025 return would technically be incorrect for both years. Just wait for the IRS notice. And FWIW I work at a bank - we're required to issue 1099-INTs for any interest of $10 or more, but we're also supposed to send paper copies unless you specifically opted for electronic statements only. Worth checking your bank settings for next year!

Don't stress too much about this! As others have mentioned, the IRS will likely catch this automatically through their matching system since banks report all 1099-INTs directly to them. For such a small amount ($43), you'll probably just get a notice in a few months adjusting your tax liability. The actual tax impact is minimal - even if you're in a higher tax bracket, we're talking about maybe $10-15 in additional tax owed. The IRS generally doesn't impose penalties for small, honest oversights like this, especially when it's clear there was no intent to evade taxes. I'd recommend just waiting for their adjustment notice rather than filing an amended return. The cost and hassle of amending isn't worth it for this amount. Keep good records of this situation in case you need to reference it later, and maybe set a reminder to double-check all your online banking portals before filing next year!
