@carolineb Thanks four your response! I live in a no-income-tax state and I am projecting to be in 22% tax bracket this year.
1. With that in mind (+W-2 and unemployment as mentioned before), according to your rule of thumb, I should send 22% + 15% = 37% of my June - Aug 1099 income this quarter (by Sep 16) I think. Please confirm if I got it right. Is there any rule of thumb for deducting standard deduction and child care credit from this quarterly tax estimation? Also, let's say I don't pay the required/rule-of-thumb % in Q3 (for example I pay only 8% of my Q3 income). But I make up for this in Q4 payment. Will I still get penalty for Q3?
2. If I take safe harbor route (110% of last year) to avoid penalty, does it make any difference paying in two chunks in Q3 and Q4 vs paying all in once in Q4?
Bottom-line is, I am trying to understand what minimum payment I should make in Q3 to avoid any penalties.
