Yes. You may participate in both a 403(b) and a 401(k) plan. However, certain restrictions may apply to the amount you can contribute. For instance, you are allowed to make a salary deferral contribution of up to $18,500 in 2018, plus an additional catch-up contribution $6,000 if the employee is 50 or older. The combined total salary deferral contribution that you make to both the 401(k) and the 403(b) plans should not exceed $18,500 or $24,500 if you qualify for the catch-up.

Note: 403(b) plans include a special provision that allows you to make salary deferral contributions of additional amounts up to $3,000 if you have at least 15 years of service with certain employers. If you meet the 15-year requirement and would like to contribute the additional amount, you should check with your employer regarding the eligibility requirements and applicable rules.
