H.R. 10588, the "Lowering Inflated Heating, Energy, and Air Conditioning Prices Act," modifies income eligibility rules for the Low-Income Home Energy Assistance Program (LIHEAP) in fiscal year 2027. The bill allows states to use their LIHEAP grants to provide energy assistance payments to households with incomes up to 75 percent of their state's median income, expanding eligibility beyond previous limits. This change affects low-income households struggling to pay heating and cooling bills, as well as state programs administering energy assistance. The legislation does not specify new funding amounts, but rather adjusts eligibility thresholds for existing LIHEAP grants to help more households access assistance during fiscal year 2027.
