On May 4, 2017, the Treasury Department and the IRS released Revenue Procedure 2017-37, which stated that the maximum contribution to an HSA for an individual with family coverage under a high deductible health plan would be $6,900 for 2018.

On March 2, 2018, the Treasury Department and the IRS released Rev. Proc. 2018-18, which superseded Rev. Proc. 2017-37, to reflect the statutory amendments to the inflation adjustments under the Act. The annual limitation on contributions to an HSA for an individual with family coverage under a high deductible health plan was changed to $6,850 for 2018, a $50 reduction from the limitation announced in Rev. Proc. 2017-37.

In response to these concerns that the mid-year reduction would impose numerous unanticipated administrative and financial burdens, the Treasury Department and the IRS have determined that it is in the best interest of sound and efficient tax administration to allow taxpayers to treat the $6,900 annual limitation originally published in Rev. Proc. 2017-37 as the 2018 inflation adjusted limitation on HSA contributions for eligible individuals with family coverage under an high deductible health plan.

The bottom line is the maximum contribution to an HSA for an individual with family coverage under a high deductible health plan is once again $6,900 for 2018.
