It is based on if your employer's health plan provides "minimum value" or not. Minimum Value basically means if the plan covers at least 60% of all anticipated costs for all of its participants.
I don't know anything about your employer's health plan, so I can't give you a definitive answer if it has "Minimum Value" or not. But if it is covers some general medical expenses but not major medical expenses, I suspect it would NOT provide Minimum Value. *IF* that is the case, you would still qualify for the full Premium Tax Credit.
If you do not qualify because your employer's health plan is considered to have "Minimum Value", a Single person at your income would only need to repay $350 for 2023.
