What is the difference between a 401(k), a 403(b) and a Roth IRA?

The main difference between a 401(k), a 403(b) and a Roth IRA is how they are taxed. A 401(k) is funded with pre-tax contributions, meaning that your money will not be taxed until you withdraw it in retirement. Contributions to a 403(b) are made with after-tax dollars but the employer makes a contribution as well. Withdrawals from a Roth IRA are tax free if certain conditions are met.
