What is the main purpose of Social Security Integration in defined contribution plans?

The main purpose of Social Security Integration in defined contribution plans is to enhance benefits for employees earning over the Social Security wage base. This concept recognizes that higher earners generally receive lower percentage replacement of their pre-retirement income from Social Security, as the benefits are capped at a specific earnings level. By integrating the pension plan with Social Security, employers can adjust the contributions or benefits to provide additional support for those making above the wage base limit, thereby ensuring that these employees receive a more adequate retirement benefit relative to their earnings. This integration allows for a more equitable distribution of retirement benefits, addressing the imbalance created by the Social Security cap.
