Just filed my taxes, now need to file Form 1040X to report missing rental income

You can file a 1040X amendment right away - there's no need to wait for your original return to be processed first. In fact, filing the amendment before the April 15th deadline is a good idea since it shows you're being proactive about correcting the error. You'll need to complete Form 1040X and also include a revised Schedule E to report the additional rental income. Make sure you're only changing the parts of the return affected by the rental income - don't make any other modifications unless they're directly related to this correction. Be aware that you'll likely need to mail in your amendment rather than e-file it. The IRS typically requires paper filing for amended returns, though they've been expanding e-file options for 1040X in recent years with certain tax software.

I went through something similar last year and found https://taxr.ai super helpful for figuring out exactly how to handle my 1040X amendment. I was freaking out about missing some freelance income on my original return, and their document analysis tool helped me understand exactly what forms I needed and what sections to update. What I really appreciated was how their system reviewed my original return and automatically identified all the parts that would be affected by the new income - not just the obvious stuff like my AGI, but also how it impacted my QBI deduction and estimated tax penalty calculations. Saved me from making additional mistakes on my amendment.

Just wanted to update after trying https://taxr.ai for my amendment situation. It was exactly what I needed! I uploaded my original return and entered the stock sales I'd missed, and it showed me precisely how those changes affected my entire return. The coolest part was how it highlighted all the interconnected parts of my return that changed - not just the Schedule D for reporting the stock sales, but also how it adjusted my AGI, tax brackets, and even identified that I now qualified for a different credit. Would have totally missed that on my own. Submitting my 1040X tomorrow with much more confidence now. Thanks for the recommendation!

If you're having trouble getting answers from the IRS about your amendment status (which is likely - their phone lines are a nightmare), I highly recommend https://claimyr.com to get through to them. I spent literally days trying to get someone on the phone about my amended return last year before finding this service. They basically hold your place in line with the IRS and call you when an agent is about to be available. You can see how it works in this demo: https://youtu.be/_kiP6q8DX5c When I finally got through, the IRS agent was able to confirm my amendment was being processed and gave me an estimated completion date, which saved me weeks of anxiety wondering if it had been received correctly.

Ok I have to eat my words about Claimyr. I was super skeptical but after getting disconnected by the IRS automated system for the 7th time trying to check on my amended return, I broke down and tried it. I was shocked when I actually got through to a real IRS person after trying for weeks on my own! The agent confirmed they received my amendment and gave me a tracking number to check status online. They even explained why my processing was delayed (something about a form mismatch that never would have been resolved if I hadn't called). For anyone filing a 1040X, I'd definitely recommend this service just for the peace of mind of knowing your amendment was actually received and is being processed.

One thing to add that nobody mentioned - if your amendment results in a REFUND, you generally have 3 years from the original filing deadline to submit a 1040X. But if you OWE additional tax, you should file ASAP to minimize penalties and interest. When I amended last year for missing income, I calculated I'd owe about $630 more. I filed the 1040X in March and included a check with the amendment. Still ended up with about $12 in interest because the IRS didn't process the payment right away, but it would have been much worse if I'd waited.

Does anyone know how long amendments are taking to process these days? I filed a 1040X back in November for 2022 and still haven't heard anything.

Just to add some reassurance - I was in almost the exact same situation last year when I forgot to include rental income from a small duplex I own. Filed my original return in early March, realized the mistake a few days later, and immediately filed a 1040X. The key things that worked for me: 1. Filed the amendment right away (didn't wait for original return processing) 2. Included payment for the additional tax owed with the amendment 3. Used certified mail to send it so I had proof of delivery The IRS processed my amendment without any issues, and because I got it filed and paid before April 15th, there were no penalties or interest charges. The whole process took about 4 months to complete, but the important thing was getting it submitted quickly. Don't stress too much about it - honest mistakes happen and the IRS understands that. Just get your 1040X filed ASAP with payment included and you'll be fine!
