Kind of a personal question that some people may not want to provide on a public forum, but I'll answer it.
I grossed 554K in 2018 as an IC for a CMG in the SE and that's NOT including taxes, ss, retirement investments, etc.. I'm not sure how many hours I worked but it was a lot and I felt miserable. Last year I made 100K less and I felt much, much better. I don't see myself working at my pre-2018 levels any more in the future. It's just not worth it and I was on the way to an early grave, was miserable to be around and my personal life was suffering. I've noticed ZERO change in my lifestyle, ability to save for retirement, or anything else at my 2019 level and that was a pleasant surprise. Which begs the question, how important is another 50K or 100K after a certain point? Probably not as much as people think. I'd work even less if I could but I was several years older than most when I became an attending and had zero retirement savings, so I'm playing catch up and am unfortunately forced to work more hours than I would like for at least the next several years taking advantage of relatively high salaries while I can.
My state has no income tax but I pay standard federal tax rates. 37% for 2019 for income over 510K, 35% for >210K, etc..
I work all 12 months out of the year. I currently average 130-150 hours/mo. I averaged around 150-160 hours/mo in 2018 I believe.
