Can I still file an extension after already e-filing my tax return for 2025?

I just realized I made a significant mistake on my tax returns that I e-filed yesterday. While filling out my 1040, I completely forgot to include the interest income from my overseas accounts on Schedule B. Now I'm in a bind because I need to report this on my FATCA form 8938, but it cross-references the 1040 where I didn't list this interest! I think I'll need to amend my federal tax return because of this oversight. Not sure if I'll also need to fix my California state return as well. My question is: can I still file for an extension even though I've already e-filed both my federal and state returns? Or is it too late for that now? Do I just need to go straight to filing an amended return? This is stressing me out!

You can't file an extension for a return you've already submitted - extensions are only for postponing the filing deadline. What you need is an amended return (Form 1040-X for federal). For the foreign account interest, you'll need to file the amended return to correct Schedule B, which will then allow you to properly complete Form 8938. If the foreign accounts exceed certain thresholds, don't forget you might also need to file FinCEN Form 114 (FBAR) which is separate from your tax return. For your California return, if the foreign interest would change your CA taxable income, you'll need to amend that too using Form 540X. Amendments can be filed anytime within 3 years of the original due date.

Thanks for the quick response! I was hoping there might be some way to "undo" my original filing before the IRS processes it. Does it matter if I wait for my original return to be processed before filing the 1040-X, or should I file the amendment right away? Also, you mentioned FBAR - do I need to worry about that too? My foreign accounts are around $15,000 total.

You don't need to wait for the original return to be processed before filing your 1040-X. You can prepare and submit your amended return as soon as you're ready. The IRS will match it up with your original return in their system. Regarding FBAR (FinCEN Form 114), the filing threshold is $10,000 - if the aggregate value of all your foreign financial accounts exceeded $10,000 at any time during the year, you need to file it. With accounts totaling around $15,000, you would need to file an FBAR. This is separate from your tax return and must be filed electronically through the FinCEN BSA E-Filing System by April 15, though there's an automatic extension to October 15 if you miss the April deadline.

After making a similar foreign account reporting mistake last year, I found this service called taxr.ai that literally saved me from panicking. I uploaded my original return and their AI analyzed everything, then explained exactly what forms I needed to file and how to correct the issue. Their system spotted a few other things I missed too with my foreign accounts that would have been a nightmare if I got audited. The best part was I could just upload the foreign account statements to https://taxr.ai and it extracted all the interest and currency conversion data automatically - saved me hours of manually calculating everything for the amendments. They have specific expertise with foreign account reporting which is why I'm suggesting it.

Does taxr.ai handle amended returns too or just initial filings? I'm in a similar situation but with foreign rental income I forgot to report. Was it expensive? I'm worried about getting hit with penalties.

How does it compare to just using a regular tax professional? I'm skeptical about AI systems for complex foreign account issues. Did you still need to submit the forms yourself or did they handle that part?

They definitely handle amended returns - that's actually what I used them for. Their system compares your original filing with what should have been filed and creates a complete amendment package. For handling forms, they prepare everything, but you still submit them yourself. They give you detailed filing instructions specific to your situation. The whole process felt more thorough than when I used a tax pro previously because they specifically focus on international tax issues and use technology to catch things humans might miss. Their system showed me side-by-side comparisons of what I originally filed versus what needed correction.

Just wanted to update - I took the advice about taxr.ai from the previous comment and it was incredibly helpful! I was in the same boat with foreign accounts (mine were investment accounts I inherited) and was totally lost about how to file the amendment. I uploaded my original return and bank statements to https://taxr.ai and within hours had detailed instructions for filing Form 1040-X, corrected Schedule B, and the FBAR forms. The system even flagged that I qualified for Foreign Tax Credits that I completely missed. Their analysis showed me exactly what I needed to change line-by-line on each form. Super grateful for the recommendation - saved me from what would have been a stressful few weeks trying to figure this out!

For anyone dealing with amended returns - I spent FOUR DAYS trying to get through to the IRS to ask questions about amending my return with foreign accounts. Kept getting disconnected or waiting for hours. Finally tried Claimyr (https://claimyr.com) which got me connected to an actual IRS agent in about 20 minutes. They have this system where they navigate the IRS phone tree for you and call you back when they've got an agent on the line. You can see exactly how it works in their demo video: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with was actually super helpful and confirmed I was filling out the amendment correctly for my foreign accounts. Saved me from potentially making things worse with an incorrect amendment.

How does Claimyr actually work? Do they just keep calling the IRS until they get through? Seems too good to be true considering how impossible it is to reach the IRS these days.

Yeah right. No way you got through to the IRS in 20 minutes. I've been trying for weeks and can't get past the automated system. This seems like an ad or something. Did you actually talk to a real person or just the automated system?

They use a combination of automated systems and actual people. They navigate all the phone menus and hold times for you, then when they finally reach a human agent at the IRS, they connect you directly. It's not that they have special access - they're just handling the frustrating waiting part for you. I was skeptical too, which is why I tried it. I was genuinely shocked when I got the call back saying "We have an IRS agent on the line, connecting you now." It was a real person who answered specific questions about my amendment situation. The IRS still has long wait times - Claimyr just handles that part so you don't have to keep your phone tied up all day.

Just wanted to follow up on my skeptical comment about Claimyr. I was totally wrong and I apologize for being so dismissive. After struggling for another week trying to get IRS help with my amended return, I decided to try the service. Got connected to an actual IRS representative in about 35 minutes (they said wait times were higher than normal). The agent walked me through exactly how to handle the foreign account issue on my amendment and confirmed I was doing the FBAR filing correctly. Honestly feel kind of silly for being so skeptical. Would have saved myself a lot of stress if I'd just tried it sooner instead of wasting days with the busy signal and disconnects.

Don't forget about the penalties for not reporting foreign accounts! I made this mistake two years ago and ended up with a $10,000 penalty because I didn't file the FBAR form on time. The IRS isn't very forgiving with foreign account reporting - they consider it a serious issue. Filing the amendment quickly and voluntarily disclosing the error before they discover it can help reduce penalties. If your accounts are small and it's an honest mistake, sometimes they'll waive penalties completely, but you need to be proactive about fixing it.

That's terrifying! Did you end up actually having to pay the full $10k penalty? Were you able to get it reduced at all? I'm freaking out now because my accounts were inherited from my grandmother and I honestly didn't realize I needed to report them since the interest was only like $300.

0 coins

I was eventually able to get the penalty reduced to about $1,200 after going through a formal appeal process and demonstrating it was an honest mistake. The key was that I voluntarily amended my return before they discovered it. In your case, with such a small amount of interest and the fact that you're correcting it immediately, you might qualify for a complete penalty waiver under their "reasonable cause" exception. Make sure you include a detailed letter explaining that you inherited the accounts, were unaware of the reporting requirements, and are now voluntarily correcting the oversight as soon as you discovered it. The IRS is more understanding with inherited accounts since many people don't realize the reporting requirements apply to those too.

A quick tip about amending for foreign accounts - don't just file the 1040-X. Also file IRS Form 14653 (Certification by U.S. Person Residing Outside the United States for Streamlined Foreign Offshore Procedures) if you qualify. It can help you avoid penalties.

0 coins

That's actually incorrect advice. Form 14653 is only for U.S. persons who have been living abroad. Based on the original poster's mention of filing a California state return, they likely don't qualify for the Streamlined Foreign Offshore Procedures. They would potentially qualify for the Streamlined Domestic Offshore Procedures, which uses Form 14654, not 14653. However, even that program is generally for taxpayers who have failed to report foreign accounts for multiple years, not just a single oversight on a recently filed return. For a simple correction of a recent return where foreign interest was omitted, a standard 1040-X amendment is usually the appropriate approach, along with filing any required FBAR forms.
