What is 104 k plan?

A 104(k) plan is not a recognized term in financial literature; it may be a typographical error or confusion with a 401(k) plan. A 401(k) plan is a retirement savings account offered by employers that allows employees to save and invest a portion of their paycheck before taxes are taken out. Contributions may be matched by employers, and funds grow tax-deferred until withdrawal during retirement. If you meant something else, please provide more context for clarification.
