Got a second W-2 after filing. Do I need to amend my taxes if it's a small amount? context: i moved (and got a new job) in mid january 2019, and was still working my previous job before moving. i received my W2 from my current employer and filed my taxes; it's all been approved and such. today, my former employer sent me a W2. my gross wages are \~$1500. is this income small enough that i shouldn't worry about amending my taxes, or do i need to go through this?
