With a traditional 401(k) plan—the type typically offered at larger companies—the employer is free to change or even eliminate its match from year to year. However, SIMPLE (Savings Incentive Match Plan for Employees) 401(k) plans and safe harbor 401(k) plans—found most often in small businesses—must provide either an employer match or non-elective contributions. Non-elective contributions are the kind made by employers on behalf of workers who don’t contribute to the plan on their own.
