Pension Plan Limits [top]

The federal government sets dollar limits as to how much an employee can contribute to their company’s qualified retirement plan each tax year. These limits are based on the cost-of-living index. If an employee reaches the age of 50 during the current tax year, they will qualify for the Catch-Up Provision… only if it is an established provision of the company’s 401(k) plan.

Some limits have changed from 2017.

  Standard 'Catch-Up' Provision
401(k), 403(b), 457 and Roth 401(k) Limits $18,500 $24,000
SIMPLE IRA Plan for 2017 $12,500 $15,500
