I filed my 2019 taxes and got a return. I worked 2 jobs and only got 1 w2 so I only filed the one and got my refund and just remembered I didn’t receive my other one. I’m sure I will end up owing. I have not received anything from the IRS, no letters or anything. What do I do? Let them find the mistake or fix it myself?
You have to amend your return to include the W-2---and do not wait until you get a letter from the IRS. If your return has been fully processed and you received your refund you can amend it now.
If you do not have the other W-2 it is up to you to make every effort to get it from the employer.
You might need to phone, drop in, email and/or snail mail an old employer to make sure they know where to send your W-2.
