Hi we filed as married jointly for tax year 2017 under my spouse's name. We just found out that we might need to file form 3520 as well.
Our questions are:
1. Do we need to file 1040X as well? or just submit Form 3520 separately to IRS?
2. Since it has already past tax extension deadline(10/15/2018), do we need to pay any penalty to IRS?
Your help is greatly appreciated!
Just note the 3520 is an informational form only and has no bearing on a tax return.
We have eFiled our 2019 tax return, and I am now completing form 3520. The form is asking me the name of the service center where my tax was submitted. I eFiled my report through Turbo Tax, how can I determine the center that is handling my return?
