The SIMPLE IRA plan can be a valuable retirement plan option for your small business owner clients, especially those with fewer than 100 employees. But for many advisors, managing SIMPLE IRA plans is a complex endeavor. With numerous deadlines and regulations to keep on top of—including everything from when a plan can be established to annual notice requirements—there are certain things every advisor should know when establishing and maintaining these plans. Let’s start with our top five.

1) The Plan Timeline

Employers can set up a plan at any time between January 1 and October 1, and that plan will be eligible for the current year—as long as that employer did not previously maintain a SIMPLE IRA plan or any other qualified retirement plan (e.g., 401(k) plan).

New employers that establish a business after October 1 can set up the SIMPLE IRA plan as soon as possible after the business comes into existence. New plans established by employers that have previously established and/or maintained a SIMPLE IRA plan, however, can be effective only on January 1.

Pro tip: In general, the effective date of a SIMPLE IRA plan is the date the provisions of the plan become effective. In other words, the plan cannot have an effective date that comes before the date an employer adopts the plan.

2) Contribution Deadlines

Here, it’s important to distinguish between the deadline for depositing employee salary reduction contributions and the deadline for making employer contributions (i.e., 3 percent match or 2 percent nonelective contribution).

• Employee contributions: The Department of Labor’s safe harbor rule for the deposit of employee salary reduction contributions requires that they be deposited no later than seven business days after receipt or withholding by employers.

• Employer contributions: The deadline for making employer contributions for the year is the employer’s tax filing deadline, including extensions (if applicable), though some employers may make matching contributions with every pay period.

Pro tip: Contributions to a SIMPLE IRA are not subject to a maximum age requirement. For example, an individual who is still employed after age 72 (70½ if the employee reached age 70½ before January 1, 2020) can continue to make SIMPLE IRA contributions.

3) Plan Modifications

IRS regulations stipulate that SIMPLE IRA plans run on a calendar-year basis and adhere to the 60-day annual notice requirement (see below). To become effective January 1 of the upcoming plan year, all plan amendments (e.g., modifying the type of employer contribution or changing the designated financial institution) must be made and notification given to employees before November 2.

Pro tip: SIMPLE IRA plans can be amended only on a calendar-year basis.

4) Plan Termination

In a nutshell, SIMPLE IRA plans cannot be terminated midyear and must run on a calendar-year basis. Also, employers are required by the IRS to notify their employees within a reasonable time before November 2 that a plan will be terminated effective the following January 1 (i.e., the upcoming plan year). As such, information regarding plan termination should be provided to employees in the annual notice.

Pro tip: Employers do not need to notify the IRS that they have terminated a SIMPLE IRA plan, but you should recommend to your clients that it is best practice to keep records of plan termination and notify their SIMPLE IRA custodian about the termination.

5) Annual Notice

Each year, employers must provide eligible employees with a SIMPLE IRA annual notice before the beginning of the annual election period—the election period generally being the 60-day period immediately preceding January 1 of a calendar year (November 2 to December 31). In other words, the annual notice must be provided to employees before November 2. If it’s the employer’s first plan year and the plan was established midyear, these dates may be modified.

Pro tip: Generally, the annual notice to employees includes the following information:

• The employees’ opportunity to make or change their salary reductions

• The employees’ ability to select a financial institution that will serve as trustee of their SIMPLE IRA, if applicable

• The plan’s designated financial institution, if applicable

• The employer’s decision to make either matching contributions or nonelective contributions

• A summary plan description

• Written notice that employees can transfer their balances without cost or penalty if the employer is using a designated financial institution
