Today, the IRS published Internal Revenue Bulletin (IRB) 2018-10 that contains Revenue Procedure (Rev. Proc.) 2018-19.
Effective for calendar year 2018, the family contribution limit for HSAs has been lowered to $6,850 from the previously set amount of $6,900.
This change came as a result of the tax reform law (P.L. 115-97) that changed the annual inflation adjustment factor from the Consumer Price Index (CPI) to a new factor known as ‘chained CPI’. This change was anticipated to slow the rate of changes in all programs under the tax code, including HSAs.
