The IRS recently released Revenue Procedure 2018-18, which reduced the annual contribution limitation for individuals with family coverage under a high deductible health plan (HDHP) for the 2018 calendar year from $6,900 to $6,850. The 2018 annual contribution limitation for an individual whose HDHP is self-only coverage was not changed and remains at $3,450. This Revenue Procedure supersedes the contribution limits published in Revenue Procedure 2017-37. This change was a result of a provision in the Tax Cuts and Jobs Act of 2017 that affected cost of living adjustments.
