Many employee benefits are subject to annual dollar limits that are updated for inflation before the beginning of each calendar year. Most of these annual dollar limits will increase in 2024. Note that some benefit limits are not adjusted for inflation, such as the contribution limit for dependent care flexible spending accounts (FSAs) and the catch-up contribution limit for health savings accounts (HSAs).

Employers should confirm that payroll systems are updated for the 2024 limits and that the new limits are communicated to employees. The following benefit limits apply for 2024:
