The first client had his LT gain tax in a step function that went from zero % to 20%.
The second client had his whole gains taxed at 20%.
Why did the first step through the different tax rates while the second went straight to the top.
And where can I find the explanation at irs.gov.  I searched and all I got was the same simplistic step function that all the rest of the Internet has.
Thanks in advance, Christopher
