Premium tax credits (PTC) are funds designed to help eligible individuals afford health insurance purchased through the Health Insurance Marketplace. The amount someone can receive in PTC is based on their income and household size.
If you opt into ICHRA, you and your dependents will become ineligible for the PTC. If you opt-out of ICHRA, depending on your ICHRA offering, you can lose eligibility for premium tax credits. If your ICHRA offer was deemed affordable (will be expressed during the onboarding process), then you and your dependents will lose your potential PTC. If your ICHRA offer was deemed unaffordable and you decide to opt-out of it, you will not lose your potential premium tax credits.
