Will you be age 50 or older on December 31 and still working? Are you already contributing to your 401(k) plan or Savings Incentive Match Plan for Employees (SIMPLE) up to the regular annual limit? Then you may want to make “catch-up” contributions by the end of the year. Increasing your retirement plan contributions can be particularly advantageous if your itemized deductions for 2018 will be smaller than in the past because of changes under the Tax Cuts and Jobs Act (TCJA).
Catch-up contributions are additional contributions beyond the regular annual limits that can be made to certain retirement accounts. They were designed to help taxpayers who didn’t save much for retirement earlier in their careers to “catch up.” But there’s no rule that limits catch-up contributions to such taxpayers.
