Today, the IRS and Treasury issued proposed regulations relating to the health insurance premium tax credit and the individual shared responsibility provision under the Affordable Care Act. These proposed regulations affect individuals who enroll in qualified health plans through Health Insurance Exchanges (Exchanges) and claim the premium tax credit under section 36B, as well as the Exchanges that make qualified health plans available to individuals and employers. These proposed regulations also affect individuals who are eligible for employer-sponsored health coverage and individuals who seek to claim an exemption from the individual shared responsibility provision because of unaffordable coverage. The proposed regulations apply for taxable years beginning after December 31.
