I Already Filed Taxes but Just Received Another W2 - What to Do?

No need to panic! This happens more often than you'd think. When you receive an additional W2 after filing, you'll need to file an amended return using Form 1040-X. The good news is that you discovered this on your own before the IRS did, which is always better. You won't need to pay back your entire refund - you'll just need to pay the additional tax owed on that $3,200 of income (minus what was already withheld on that W2). Since you're filing the amendment promptly, you shouldn't face any significant penalties. For the process itself, you can file an amended return through TurboTax since that's what you used originally. Have all your original tax documents plus this new W2 handy. The software will help recalculate everything. Just note that amended returns can't be e-filed - you'll need to print and mail it.

I was in a similar situation last year and found taxr.ai really helpful for figuring out exactly what I needed to do. I had filed through H&R Block and then got a late 1099 and wasn't sure about the amendment process. I uploaded my documents to https://taxr.ai and it analyzed everything, showed me the tax impact of the additional income, and guided me through the amendment process step by step. It was way less stressful than trying to figure it out myself or waiting on hold with the IRS for hours. They even explained what penalties might apply (thankfully minimal in my case).

Just wanted to update - I tried taxr.ai after seeing it mentioned here and it was exactly what I needed! I uploaded my original return and the late documents I received, and it clearly showed me the tax difference. It was only about $210 I would owe after the amendment, and the system walked me through exactly how to file the 1040-X. The step-by-step guidance made it super easy, and I was able to print everything out and mail it yesterday. They even provided a cover letter template to send with my amendment explaining the situation. Honestly saved me so much time and stress compared to when I tried to amend a return myself a few years ago.

I went through something similar in 2023, but it was much worse since I didn't discover the missing W2 until the IRS sent me a notice SIX MONTHS later. Spent weeks trying to call them with no luck - always disconnected due to "high call volume". Finally found https://claimyr.com and watched their demo at https://youtu.be/_kiP6q8DX5c. They got me connected to an actual IRS agent in about 20 minutes when I'd been trying for weeks on my own. The agent walked me through the whole amendment process and helped resolve the penalties that had been building up.

I have to admit I was completely wrong about Claimyr. After posting that skeptical comment, I decided to try it anyway since I was desperate to resolve my tax issue before the deadline next week. I figured I had nothing to lose at that point. The service actually connected me with an IRS representative in about 35 minutes. I didn't have to sit on hold or keep redialing - they literally just called me when they had an agent on the line. The agent was able to pull up my account and confirm exactly what I needed to do with my amendment, including how to minimize the penalties. Saved me days of frustration and potentially hundreds in additional penalties. Sometimes it's good to be proven wrong!

Pro tip from someone who works at a tax office: If you use tax software to prepare your amendment, DOUBLE CHECK the software's calculations before filing. I've seen numerous cases where the software miscalculates amended returns, especially when there are credits involved or if you paid with your original return. Also, make absolutely sure you're using the correct tax year forms. The 1040-X for 2024 is different from previous years, and using the wrong form will just delay processing.

Don't forget that most states also require you to file an amended state return if you amend your federal! This is something a lot of people miss. Usually you need to wait until your federal amendment is processed first, then file the state amendment with a copy of your federal 1040-X attached.
