The article didn't even make sense.
It said he paid 1million in 2016
And
4 million in 2017
Then it said it was a preemptive payment and that his actual taxes were lower, and the credit covered future years taxes..
Well either he's paid 5 million over 5 years if it's already gone or he just paid enough taxes to cover himself until the year 3000 for no apparent reason..
