Ken is a self$-$employed architect in a small firm with four employees: himself, his office assistant, and two drafters, all of whom have worked for Ken full$-$time for the last four years. The office assistant earns $$30,000$ per year, and each drafter earns $$40,000.$ Ken$$s net earnings from self$-$employment $($after deducting all expenses and one$-$half of self$-$employment taxes$)$ are $$380,000.$ Ken is considering whether to establish a SIMPLE plan and has a few questions.

Required:

Is he eligible to establish a SIMPLE plan?

Is he required to cover his employees under the plan?

If his employees must be covered, what is the maximum amount that can be contributed on their behalf?

D$.$ If the employees are not covered, what is the maximum amount Ken can contribute for himself?

E$.$ If Ken is required to contribute for his employees and chooses to contribute the maximum amount, what is the maximum amount Ken can contribute for himself? $($Hint: Calculate the employee amounts first.$)$ Ignore any changes in Ken$$s self$-$employment tax.
