There are cases where if your salary goes up, your take-home goes down, especially for lower income levels. It’s just not on the basis of tax brackets. There are means-tested benefits that you can lose if you cross certain income levels where an increase in income of $5 can cost you thousands of dollars.

Yup. Most are for lower income levels but some affect middle class & up as well

(electric vehicle credits, financial aid for university, first time homeowner credits, or affordable homeownership breaks... etc)
