Re: Affordable Care Act subsidies:
It is a sliding scale. All the way from 1X to 4X. But you are correct at 4X it cuts you off. Which I believe is over $90K of income.
Depends on household size. Good estimator here:
https://www.kff.org/interactive/subsidy-calculator/
Families/individuals are eligible for a subsidy if their modified adjusted gross income (MAGI) is less than 400% of the federal poverty level. MAGI for most people is their AGI.
In 2020 for our family of 5, if we had an AGI of $120,680 we got a PTC of $9,228. If we made $120,685 we got a PTC of $0. That’s the subsidy cliff.
