There are a lot of things (IETC for example, or benefits, or health insurance) which have $ cutoffs. Or tax breaks (i.e. electric vehicle credit) that only apply below a certain income. Exceeding those fixed points can certainly make you make less money.
One thing I ran into recently was fiscal incentives for homeownership (though not directly related to taxes) - there is a cutoff at a certain income level where if you stay below it you get a $10K credit towards closing costs. The tax code is full of things like that (or getting your student loans forgiven if you make less than $X for Y years).
If you want to see how bad the welfare cliffs are, there are cases where a single mother is better off making $28,000 per year (and receiving all federal benefits), than making ~$70,000 per year (and qualifying for none of them).
