FSA and HSA Comparison and Changes to HSA Limits
What are the differences between a medical flexible spending account (FSA) and a health savings account (HSA)? Both are tax-favored accounts that allow participants to pay for qualifying medical expenses with pretax dollars, but each is governed by different legislation with different requirements:

As a result of the tax reform legislation passed at the end of 2017, the IRS released Revenue Procedure 2018-18 on March 5, which decreased the 2018 family HSA contribution by $50, from $6,900 to $6,850. The contribution limit for participants enrolled in individual high-deductible health plan (HDHP) coverage, as well as the other limits for HSA-qualified HDHPs, remains unchanged.
The new tax law changed the basis for calculating inflation from the standard Consumer Price Index to the chained CPI, which results in lower cost-of-living increases. Using the chained CPI will also lower the cap on salary-reduction contributions to medical FSAs, but Rev. Proc. 2018-18 does not address those limits.
Employers should notify employees of this reduced contribution limit as soon as possible. To avoid penalties, employees enrolled in family HDHP coverage who have elected to contribute $6,900 must decrease their elections to $6,850, and employees who have already contributed the maximum $6,900 before March 5 must withdraw their excess contributions, including any interest on the excess contributions, as taxable income by April 15, 2019. It appears employers will not need to treat the excess contributions as taxable wages for W-2 purposes because they presumably had a reasonable belief at the time of the contribution (before March 5) that it was excludable from wages. Further, employers may automatically reduce employee elections to the new maximum amount.
