Verified step by step guidance

1. Understand the nature of 401(k) and 403(b) retirement accounts. Both are tax-advantaged retirement savings plans, but they are designed for different types of employers.
2. Recognize that 401(k) plans are typically offered by for-profit organizations. These plans allow employees to contribute a portion of their salary either pre-tax or post-tax (Roth contributions) to their retirement savings.
3. Understand that 403(b) plans are specifically designed for employees of non-profit organizations, such as charities, religious institutions, and public schools. Contributions are generally made on a pre-tax basis.
4. Note that the primary difference between these two plans lies in the type of employer offering them: 401(k) plans are for for-profit employers, while 403(b) plans are for non-profit organizations and public schools.
5. Review the incorrect options provided in the problem to ensure clarity: FDIC insurance does not apply to either plan, both plans have contribution limits set by the IRS, and both allow pre-tax contributions (with Roth options available for 401(k) plans).
