There are several benefits for those who are their own boss, but the financial advantages are typically not what comes immediately to one's mind. For most people, any monetary benefit is something really thought of last. What does come to mind are self-employed people taking long lunches, coming to work when they want or telecommuting from home, and being able to wear casual attire forte whole day.
However, the financial advantages of self employment may be a lot more attractive than the casual clothes and long lunches. Any benefits you have are not automatic like a salaried employee. They are earned from hard work and becoming an expert in your field. If you're self-employed person you're well aware of this aspect.
