Haw. Code R. § 17-1724.2-1
This chapter describes the modified adjusted gross income (MAGI) based income methodology. MAGI-based income methodology, established by the Affordable Care Act, is used to determine financial eligibility for individuals described in chapters 17-1715 (Children Group), 17-1716 (Pregnant Women Group), 17-1717 (Parents and Other Caretaker Relatives Group), and 17-1718 (Adults Group), collectively referred to as "MAGI groups." MAGI-based income methodology incorporates a household's composition, size, and the treatment of certain types of income. These conditions are generally based on information from the previous tax year, whether the household expects to file a tax return for the taxable year in which medical assistance is sought, and any expected change in circumstance.
