bluejuice,
hard to follow the numbers you have, but, to me it looks as if you are taking the income-tax exclusion=taxable income and then hitting US tax rate at that adjusted income.
but, in a screwjob of all foreign workers, congress adjusted that so that your income is taxed at the highest rate versus the lowest.
so 100k-82.4k=17.k which used to be taxed at (15% of income over 7825) is now taxed at (28% of the amount over 77,100)
certainly not a tax lawyer, though and willing to admit that I could be wrong
so, 28% of the income above 82.4k, then 33% of the income above 160.9k
