How will the state's HSA contribution proration be calculated for midyear enrollments?
The state contribution proration is calculated based on the number of pay dates between the effective date of the State HDHP coverage and the end of that year. For example, if an employee and spouse enroll in the State HDHP effective March 21, 2021, 20 pay dates remain in the calendar year, so the calculation would be: $1,500 / 26 * 20 = $1,153.85.
