Part II - Employer Offer and Coverage
Line 15: Employee Share of Lowest Cost Monthly Premium
in line 15, Employee Share of Lowest Cost Monthly Premium for Self-Only Minimum Value Coverage, is used to report the employee share of the lowest-cost monthly premium for the coverage you offered. Even if the employee decided to enroll in a plan with more expensive coverage, you'll need to enter the lowest amount available for that employee. If the coverage you offered didn't require any premium contributions on the part of the employee, enter $0.00 for the amount.
Pro-tip: Line 15 will only show an amount in it if Code 1B, 1C, 1D, or 1E is entered on Line 14.
Note: Lines 14 through 16 are used to indicate the offer of coverage for the employee, and the employee's share of the monthly premium and Section 4980H Safe Harbor relief (if applicable).
