get a new agent because he's wrong. form 8962: once your household income (line 3) goes over the poverty line of about $17,400 (unless you live in Hawaii or Alaska slightly higher) a % is computed on line 5. if it's 150% or less there is no repayment. also, household income may not be the same as adjusted gross income. 100% of social security benefits are included for household income purposes as well as municipal interest and certain excluded foreign earnings. if it's more than 150% then a fraction from the tables included in the form's instructions goes to line 7. household income line 3 is multiple by the number on line 7 = line 8a. that's how much you should be contributing for an SLCSP policy. if it's more than the total in column B of the 1095A you must repay the entire advance premium up to $2800. if the total of column B on the 1095A is more than line 8a that's the PTC advance you should have gotten. if it s less than what you got you repay the difference.
Up to $2800
admittedly this is kind of complicated so you may need to see the actual form to see why but it's not uncommon this year for taxpayers to have to pay some or all of the PTC advance.
