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.
The main difference between the pre-tax and Roth 401(k) is whether you pay taxes now (Roth) or at the time you withdraw the money (pre-tax). Most people are better off in the pre-tax 401(k) because their income is generally lower when they need the money during retirement.
