2024 Cost of Living Adjustments

By Louis F. LiBrandi, Partner

Plan sponsors should review the cost-of-living adjustments (COLAs) to determine what, if any, changes need to be communicated to employees by means of orientation meetings and enrollment forms. In addition, the amounts may need to be updated and/or keyed into the payroll or other human resources information systems used by the employer to monitor contributions made to an employee benefit plan.

The table below contains the dollar limitation for retirement plans and other benefit plan limits and thresholds for the 2022 through 2024 tax years. In 2024 many of the amounts have been increased.
