Employee Benefit Plan Limits for 2018

By GBS Team

Group Benefit Strategies Audit and Claim

Many employee benefits are subject to annual dollar limits that are periodically updated for inflation by the Internal Revenue Service (IRS). The following commonly offered employee benefits are subject to inflation-adjusted dollar limits:

  • High deductible health plans (HDHPs) and health savings accounts (HSAs);
  • Health flexible spending accounts (FSAs);
  • 401(k) plans; and
  • Transportation fringe benefit plans.

The IRS typically announces the dollar limits that will apply for the next calendar year well in advance of the beginning of that year. This gives employers time to update their plan designs and make sure that their plan administration will be consistent with the new limits.

This Compliance Overview includes a chart of the inflation-adjusted limits for 2018. Although some of the limits will remain the same, many of the limits will increase for 2018.


  • HSA contribution limits for individuals with self-only or family coverage under an HDHP
  • Employees’ elective deferrals to 401(k) plans, pre-tax and Roth
  • Health FSA limit for employee pre-tax contributions
  • Monthly limits for transportation fringe benefit plans
  • HDHP minimum deductibles and maximum out-of-pocket limits


  • Tax exclusion for dependent care FSA benefits
  • Catch-up contributions to an HSA
  • Catch-up contributions to a 401(k) plan
