Nearly two-thirds of plans provide employer matching contributions today. Most common is a dollar-for-dollar up to a specific agreed percentage of pay which is commonly up to 6% of yearly income. The employer matching program is any potential additional payment to an employeeâs 401(k) plan.
Plan contribution limits for the individual are equal to a typical company-sponsored 401(k), but the sole proprietor can also make an employer contribution to an independent 401(k), thereby raising the total contribution allowed.
