In Revenue Procedure 2018-18, the Internal Revenue Service announced a reduction in the HSA contribution limit for family coverage in 2018 to $6,850 from $6,900. The self-only HSA contribution limit for 2018 remains unchanged at $3,450.
This change is a technical result of the Tax Cuts and Jobs Act, which adjusted the method for calculating inflation. Although the reduction may appear somewhat small, it may cause certain employees to inadvertently contribute over the limit. For instance, an employee who front-loads his or her annual contribution may have already exceeded the new limit.
The IRS has not issued any transition relief for excess contributions made in 2018 by employees relying on the original contribution limit announced in Revenue Procedure 2017-37. However, certain members of Congress and several employer groups recently petitioned the IRS to issue such relief. In the absence of relief, employers may wish to adjust their payroll systems and to communicate the revised limit to their employees.
