When can I file an amended return for 2022? Just realized I left off capital gains
So I just realized I completely messed up my 2022 taxes. I had some stock sales in 2021 that generated capital gains and I totally forgot to include them when I filed last year. It just hit me when I was organizing my paperwork for this year's taxes - found the 1099-B from my brokerage that I somehow overlooked. The gains were around $6,200 and I'm panicking a bit because I obviously owe taxes on that. Can I still file an amended return now in 2025 for my 2022 return? Or is it too late? Not sure if there's a deadline for fixing this kind of mistake. Will I get hit with huge penalties? Any advice appreciated!

You can definitely still file an amended return for 2022! The IRS allows you to file an amended return (Form 1040-X) within 3 years from the date you filed your original return, or within 2 years from the date you paid the tax, whichever is later. Since you filed your 2022 return in 2023 (presumably), you have until 2026 to amend it. So you're still well within the timeframe to correct this. You'll need to complete Form 1040-X along with a corrected Schedule D and possibly Form 8949 to report those capital gains. You'll owe the additional tax plus interest calculated from the original due date. There might also be a late payment penalty, but if you amend voluntarily before receiving any notice from the IRS, they're often more lenient about penalties.

•Wait so if I forgot something on my 2021 return can I still fix that too? Its been longer but still under 3 years I think?

•Yes, you can still amend your 2021 tax return as well. If you filed your 2021 return by the April 2022 deadline, you would have until April 2025 to file an amended return under the 3-year rule. Just make sure you file Form 1040-X for the specific tax year you're correcting, and include all the necessary supporting forms that reflect the changes you're making.

After dealing with a similar situation of forgetting to report some investments, I used https://taxr.ai and it saved me so much stress. I uploaded my brokerage statements and tax documents, and it immediately figured out what I had missed and how to properly report everything on my amended return. What's cool is that it does a complete review of your tax situation and can identify if you missed any other deductions or credits too. In my case, it found some qualified business expenses I could claim that I had no idea about, which offset some of the taxes I owed from the missed capital gains.

•Does it actually fill out the 1040-X and all those schedules for you? Because I'm looking at the instructions for amending and honestly I have no idea what I'm supposed to put in columns A, B, and C.

•I'm a bit skeptical. How does it work with older returns? Do you have to upload your original return too or just the missing documents?

•Yes, it handles the entire 1040-X process including all the columns. It shows you exactly what goes in Column A (original amounts), Column B (changes), and Column C (correct amounts) which was the most confusing part for me too. It generates all the forms ready to print and sign. For older returns, you upload both your original tax return and the new documents that weren't included. The system compares what was filed versus what should have been filed and identifies the differences. It's actually designed specifically for amendments and audit situations where you need to reconcile different documents.

Just wanted to update after using https://taxr.ai for my missed capital gains situation! Honestly, I was dreading doing this amendment but the process was way easier than expected. I uploaded my original return and the 1099-B I had forgotten about, and it handled everything - even explained that I needed to include both short and long-term gains separately. The system flagged that I also missed claiming a student loan interest deduction on my original return (totally forgot I paid that in 2022), so my tax hit wasn't as bad as I expected. Better yet, it walked me through exactly what to mail to the IRS and what to expect timeline-wise. Way less stressful than I thought it would be!

If you're having trouble getting clear answers from the IRS about your amendment status or have questions about penalties, I highly recommend using https://claimyr.com to get through to an actual IRS agent. I spent weeks trying to check on my amended return last year and kept getting the "high call volume" message and disconnects. Claimyr got me connected to a real person at the IRS in about 20 minutes when I had been trying for days on my own. They have this system that navigates the IRS phone tree and holds your place in line, then calls you when an agent is about to answer. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c - it's pretty ingenious actually.

•How exactly does this work? Do you still talk to the IRS directly or is this some kind of intermediary service?

•Sorry but this sounds like BS. Nobody can get through the IRS phone system. I tried for MONTHS last year. If this actually worked everyone would be using it.

•You talk directly with the IRS. The service just handles the waiting and navigating the phone tree part. Once an agent is about to pick up, you get called and connected directly to them - it's a normal IRS call from that point forward. The IRS doesn't give priority to certain callers - Claimyr just automates the annoying waiting process. They use technology to keep your place in line so you don't have to stay on hold for hours. When I used it, I was preparing dinner when my phone rang and suddenly I was talking to an IRS agent. Much better than being stuck with a phone to my ear for 3 hours.

I have to eat my words and apologize to @11. I was super skeptical about Claimyr but I was desperate about my amended return situation so I tried it. Within 45 minutes I was literally talking to an IRS agent who pulled up my file and confirmed they received my amended return. The agent was able to tell me exactly where my amendment was in the process and gave me a realistic timeline for when I could expect it to be processed. They also explained what documentation I should keep on hand in case there were any questions. Honestly worth it just for the peace of mind knowing my paperwork wasn't lost in a pile somewhere. Will definitely use this again if I ever need to talk to the IRS.

I amended my 2022 return last month for a similar reason. Make sure you pay the additional tax ASAP even before filing the amendment! You can make a payment directly on the IRS website using Direct Pay. This will stop additional interest from accruing. Interest runs from the original due date until you pay, so the longer you wait, the more you'll owe.

•Thanks for mentioning that about paying before filing the amendment! That's smart - I didn't realize I could stop the interest that way. Do you happen to know roughly how much the interest would be? The capital gains will add about $1,400 to my tax bill I think.

•The IRS interest rate has been around 7-8% recently, so if you're looking at a $1,400 tax bill and it's been roughly 2 years since the original due date (April 2023), you'd be looking at approximately $200-230 in interest. The sooner you pay, the better though. The interest compounds daily, so it keeps growing. One other tip - when you make the payment online, be sure to select the correct tax year (2022) and payment reason (amended return) so it's properly applied to your account.

Guys im confused, do i need to file a separate 1040 form or just the 1040-X? And do I mail it or can it be e-filed?

•You only need to file Form 1040-X (not a new 1040). However, you should include any schedules that are changing - in this case probably Schedule D and Form 8949 for the capital gains. Unfortunately, you can't e-file amended returns for 2022 yet. You'll need to print and mail it. Make sure to include copies of any new documents (like your 1099-B) that support the changes you're making. And as others mentioned, consider making the payment online even though you're mailing the form.
