There is now a FIFTH bracket for those making over $1,000,000 and the ones before it ( 3 or 4 of them ) are off.
Also, these figures are not retroactive, so everyone's 2017 fillings will be computed on the tables of today AND these tables are in flux ( meaning that many of them go up/people in lower brackets get bumped up to a higher one, each year after 2018) in the succeeding years.
The million dollar bracket is there. Do you have a link to the table you’re referring to?
