Final answer:
Margaret should consider a Simplified Employee Pension (SEP) IRA as it allows flexibility for employer contributions and permits employee contributions to their Individual Retirement Account (IRA), meeting her requirements for a retirement plan.
Step-by-step explanation:
Margaret is interested in setting up a retirement plan that allows for employee contributions but keeps employer contributions low. Considering her needs, a suitable retirement plan would be a Simplified Employee Pension (SEP) IRA. This type of plan is ideal for small businesses and self-employed individuals as it allows employers to make contributions to their employees' retirement savings directly to an Individual Retirement Account (IRA) established in the employee's name. Employers can contribute a fixed percentage of up to 25% of an employee’s pay into a SEP IRA, rendering it flexible in terms of the amount the employer wishes to contribute annually, which addresses Margaret's requirement to keep employer contributions low. Employees cannot contribute to a SEP IRA themselves, but they could also set up and contribute to a Traditional or Roth IRA for additional retirement savings, taking advantage of tax-deferred or post-tax benefits, respectively.
