A 401(k) is a feature of a qualified profit-sharing plan that allows employees to contribute a portion of their wages to individual accounts. Some of the key features of 401k plans are:
• Elective salary deferrals are excluded from the employee’s taxable income (except for designated Roth deferrals).
• Employers can contribute to employees’ accounts.
• Distributions—including earnings—are includible in taxable income at retirement (except for qualified distributions of designated Roth accounts).
In Michigan, as in all states, a 401(k) plan is governed by federal law, specifically the Employee Retirement Income Security Act (ERISA) and the Internal Revenue Code. Employees in Michigan can elect to defer a portion of their salary into their 401(k) plan, which reduces their current taxable income, except in the case of Roth 401(k) contributions, which are made post-tax. Employers have the option to make contributions to their employees' 401(k) accounts, which can be in the form of matching contributions, non-elective contributions, or profit-sharing contributions. Upon retirement or when the employee takes distributions from the plan, the funds, including any earnings, are subject to federal income tax, unless the funds are from a Roth account and the distribution is qualified. It's important to note that while the 401(k) is a federal program, Michigan state tax laws generally conform to federal tax treatment of 401(k) contributions and distributions.
