Safe Harbor 401k Vs. Traditional 401k

 Which one is better? 

It depends on the design that best satisfies the priorities of your business. For all businesses, the IRS permits a selection of one of (2) types.  Certain requirements apply to each, to meet qualification rules for ongoing tax benefits.

A Safe Harbor 401k and Traditional 401k each permit the same contribution limits by employees; however, there are specific rules and features regarding employer contributions and testing that differentiate the plan types. Our team will detail these plan elements to help you with the best fit before implementation. We also stay connected after your plan is in place to assure that the original blueprint is current with your dynamic business developments and benefit intentions.
