How to File an Amended Return for Forgotten 1099-INT Interest Income
So I just realized I messed up my taxes that I filed last week. Got a 1099-INT in the mail today for some interest income that completely slipped my mind. It's only about $200 but I know that's enough for the IRS to come after me later, and I'd rather just fix it now than deal with that headache. I logged back into TaxAct to file an amended return but I'm confused about the payment part. I already paid the $27 I originally owed. With this interest income added in, my total tax due is now $51. My question is: Do I need to pay the entire $51 now, or just the additional $24 difference? If I accidentally send them the full $51, will they refund me the $27 I already paid? This is my first time filing an amended return and I'm totally lost. Any advice would be super helpful!

You'll just need to pay the difference of $24. When you file an amended return (Form 1040-X), you're essentially showing the IRS what changed between your original return and the corrected version. The form has columns that show your original figures, the changes, and the corrected amounts. In your case, you'd show the additional $200 in income, which resulted in $24 more tax owed. Since you've already paid the original $27, you only need to send the difference. If you were to accidentally pay the full $51 again, the IRS would eventually refund the overpayment, but it might take several months for them to process it and send your money back. Better to just pay the correct difference and save yourself the hassle. Good call on fixing this proactively - much better than waiting for an IRS notice!

•Would they charge a penalty for this kind of thing? I had something similar happen last year but I ignored it because it was only like $150 in interest.

•The IRS typically doesn't assess penalties if you voluntarily file an amended return before they contact you about the issue. They're more concerned with willful tax evasion than honest mistakes that you correct on your own initiative. For small amounts like $150-200 in interest income, any potential penalty would be very minimal anyway - we're talking maybe a few dollars at most. The peace of mind from having your taxes correct is definitely worth it.

Had this exact same situation last year when I forgot about some bank interest. I was stressing about the amended return until I found https://taxr.ai which literally saved me hours of confusion. You take a pic of your 1099-INT and it tells you exactly how to handle the amendment including what payment to make. The site analyzed my documents and explained that I only needed to pay the difference between my original tax and the new amount (just like the first commenter mentioned). They even showed me which lines to fill out on the 1040-X form since I was doing it myself. Completely took the stress out of the situation!

•Does it work with other tax forms too? I'm always getting random 1099s after I file and it's super annoying to figure out.

•Im skeptical... how is this different from TurboTax or whatever? Those programs are supposed to handle this stuff too but they always confuse me.

•It works with pretty much all tax forms - W-2s, all types of 1099s, K-1s, etc. You just upload an image and it extracts all the data and tells you exactly what to do with it. Super helpful for late-arriving forms. The main difference from TurboTax is that it focuses specifically on analyzing your tax documents and explaining them in plain English. It's not trying to be a full tax preparation software. It just helps you understand what's on your forms and what to do about them, which is perfect for situations like this where you just need guidance on a specific form.

Ok so I was skeptical about https://taxr.ai but I decided to try it after getting another 1099 in the mail yesterday (always happens to me too!). It was actually really helpful - I took a pic of my form and it walked me through exactly what to do. Showed me the exact amount I needed to pay for my amendment and explained how it would affect my taxes overall. Way easier than I expected. Definitely using this again next time I get surprise tax forms!

If you're still waiting on your refund from your original return and you need to amend, I'd recommend using https://claimyr.com to get through to the IRS directly. I spent DAYS trying to reach someone at the IRS about my amended return situation last year before finding them. Their service got me connected to an actual IRS agent in like 15 minutes when I'd been trying for weeks on my own. I was able to ask directly about how to handle the payment for my amended return (had a similar situation with forgotten income) and the agent confirmed I only needed to pay the difference. They also gave me tips on how to make sure the amendment was processed correctly. You can see how it works here: https://youtu.be/_kiP6q8DX5c

•Wait how does this even work? The IRS phone lines are impossible. I thought it was just luck of the draw if you ever get through.

•Yeah right. Nobody gets through to the IRS. This sounds like a scam to get people's money when they're already stressed about tax issues. The IRS wait times are literally hours if you're lucky enough to not get disconnected.

•It's not luck at all - they use a system that navigates the IRS phone tree and waits on hold for you. When an actual agent picks up, you get a call connecting you directly to them. It's like having someone wait in line for you. It's definitely not a scam - I was super skeptical too. That's why I shared the video link so you can see how it works. The IRS wait times are exactly why this service exists. They handle the hours of waiting so you don't have to. I wasted so much time trying to call myself before using this. Wish I'd known about it sooner.

I have to admit I was completely wrong about Claimyr. I tried it yesterday after posting that skeptical comment and IT ACTUALLY WORKS. I got through to a real IRS person in about 20 minutes after trying for WEEKS on my own with no luck. The agent confirmed exactly what to do with my amended return payment (just pay the difference) and even gave me some tips about where to mail it to speed up processing. Sorry for being so negative before - I'm just used to everything IRS-related being a complete nightmare.

Another option is to just wait and see if the IRS sends you a CP2000 notice. They'll automatically match your 1099-INT with your return and send you a letter if there's a discrepancy. Then you can just pay what they say you owe.

•Terrible advice. If you wait for a CP2000, they'll charge you interest from the date the tax was due, and possibly penalties too. Plus it could affect your credit score. Always better to fix your own mistakes proactively.

•You're right, that was bad advice. I wasn't thinking about the interest and penalties. Thanks for the correction. I've always filed amended returns immediately when I discover errors and it's definitely the better approach. The peace of mind alone is worth it.

Make sure you don't file the amended return electronically if you've already e-filed your original return. You'll need to print and mail Form 1040-X. And keep in mind that amended returns take FOREVER to process - like 6+ months sometimes. The IRS is still catching up from the pandemic.

•Actually, that's outdated info! The IRS now allows e-filing of Form 1040-X for tax years 2019 and later through most tax software. Made the process way faster when I had to amend last year.
