I am not a tax professional...
Based on the 1099-DIV forms that I have received I will probably owe several thousand dollars of additional federal tax to the IRS for the year 2016. This additonal amount is more the 90% of the tax withheld in 2016, 100% of the tax paid last year, etc. etc.
If I mail in this additional tax owed with form 1040-ES by 04/18/17 I will not have to pay interest penalty to the IRS, right? (Page 2 of instructions.)
What if I mail in the additional tax owed with my 1040 by 04/18/17 instead of using form 1040-ES?
