Late payment charges arise when you pay some, or all, of the premium owed after the due date. Late charges include both interest and penalty. The current rules for late payment changes apply to late premium payments for plan years beginning in 2016 or later. Different rules apply for earlier plan years.
The “Late Payment Charges” section of each year’s Comprehensive Premium Filing Instructions provides detailed information about late charges that apply with respect to that year (e.g., how interest and penalties are determined, automatic penalty waivers, how to request a penalty waiver). Instructions for the current and prior years are available on the Premium Filing Payment and Instruction webpage.
