Those billions aren’t uniformly taxed: that’s what they were pointing out.
Actually, those billions wouldn't have been taxed at all. That was part of the deal: Amazon gets all of the income taxes that are paid by their employees in the first ten years.
That being said, there's no city-level income tax rebate. Assuming the tax brackets currently in effect hold steady until the full 25k jobs promise was fulfilled, the city of New York would get ~3.8% of $150k * 25k jobs = ~$142.5 million/year once the 25k job mark is reached [2].

[1]: Note how the 6.85% bracket only applies to income above $215.4k; income above $1.08 million gets taxed at 8.82%; consequently Amazon will get more rebated than employees paid in income tax the vast majority of the time.
