Self-employment can offer an excellent work-life balance, as well as other freedoms and lifestyle benefits! Seriously though, self-employment will likely be the cause of you working 80 hours a week.
It’s also worth noting that in the case of both retirement plans, the employer (you) and employee (you) have to set up accounts associated with the plan. So the employer creates the pension plan, and then the employee has a “participant” account.
A SEP IRA stands for “Simplified Employment Plan” IRA. It’s a retirement plan that is intended for businesses, and allows participation by owners and employees.
