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.
- 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).
