On the old 1040 tax forms you report any repayment of excess Premium Tax Credit on line 46, and any additional PTC owed to you on line 69. For 2018, repayment of the PTC subsidy is reported on Schedule 2 Tax (line 46) and additional subsidy tax credit is listed on Schedule 5 (line 70) Other Payments and Refundable Credits. It’s important to know where to find these numbers if you are trying to forecast for the next year and are using the past figures as a guide.
