Example. In 2010, Employer F contributes $1,000 for the calendar year to the HSA of each full-time employee who is an eligible individual with self plus one HDHP coverage. Employer F contributes $1,500 for the calendar year to the HSA of each employee who is an eligible individual with self plus two HDHP coverage. The deductible for both the self plus one HDHP and the self plus two HDHP is $2,000. Employee A, an eligible individual, is a nonhighly compensated employee with self plus one coverage. Employee B, an eligible individual, is a highly compensated employee with self plus two coverage. For the 2010 calendar year, Employer F contributes $1,000 to Employee A's HSA and $1,500 to Employee B's HSA. Employer F's HSA contributions satisfy the comparability rules.
