The three major areas of difference between a 401(k) and a Roth IRA are tax treatment, investment options and possible employer contributions. 401(k) plans and Roth IRAs are both popular tax-advantaged retirement savings vehicles.
IRA contribution limits are set by the IRS, whereas 401(k) limits are set by the employer. 401(k) contributions are taken from an employee's paychecks on a pre-tax basis, which means that payroll taxes aren't paid on them.
