> if you don't end up making that amount this year ... you'll be forced to pay back the entire tax credit My understanding is that the repayment amount is capped based on your income, so, for example, a person whose income came in just below the FPL (or just below 138% of the FPL in states that expanded Medicaid) would be liable for at most $300 of the advance premium tax credit.
