You wrote that you are a few years out from retirement....let's hope that the ACA subsidy is still around then and that preparing for "the cliff" is still an issue!
Here is my real-life experience: Our income the last few years has been specifically managed to avoid the cliff. Yet, I don't think the tail wags the dog. It's just that our income "naturally" will fall close to the cliff threshold and, like you wrote, I too don't want to feel stupid for earning $1 too much and losing out on it.
Well, the way ACA subsidies work, there **is** some tail wagging the dog.
That isn't true for the income tax, because it is graduated and the brackets are *marginal*, not retroactively applied to the entire income. In other words, with the income tax, if you make $X+1 instead of $X pre-tax, you will never wind up with less *after* tax. That last dollar may be taxed at a higher rate, but all the previous dollars are still taxed at their previous, lower rate.
But the cliffs in the ACA do not work that way. That creates a situation where a MAGI of $X+1 could *cost* you hundreds, if not thousands, or dollars a year in lost subsidy.
So yes, for ACA subsidy purposes, the tail should wag the dog, at least within reason (i.e. you won't turn down a "take it or leave it" $20K windfall because you lose a $5K subsidy). But you might want to pass on a smaller amount of income which results in an even larger loss of subsidy, and take whatever steps you reasonably can to get on the "right" side of the nearest cliff.
