IRS Form 5304-SIMPLE – In today’s competitive job market, offering robust retirement benefits can help small businesses attract and retain top talent. One popular option is the Savings Incentive Match Plan for Employees (SIMPLE) IRA, which provides a straightforward way for employers with 100 or fewer employees to contribute to their workers’ retirement savings. IRS Form 5304-SIMPLE serves as a model document for establishing this plan when employees select their own financial institutions. This article explores everything you need to know about Form 5304-SIMPLE, including its purpose, setup process, eligibility rules, contribution limits for 2026, and more. Whether you’re a small business owner or HR professional, understanding this form can simplify your retirement plan administration.
What Is IRS Form 5304-SIMPLE?
IRS Form 5304-SIMPLE is a model plan document designed for small employers to create a SIMPLE IRA plan under Section 408(p) of the Internal Revenue Code. It allows eligible employees to make pre-tax salary reduction contributions to their individual retirement accounts (IRAs), while requiring employers to provide either matching or nonelective contributions. Unlike more complex plans like 401(k)s, SIMPLE IRAs have minimal administrative requirements—no annual IRS filings are needed, and setup is as simple as completing the form and notifying employees.
The form itself is not filed with the IRS; instead, employers keep the original for their records. It includes provisions for employee eligibility, contribution rules, and model notifications to meet disclosure requirements. As of 2026, the form remains based on its March 2012 revision, but contribution limits and other elements adjust annually for inflation.
Key Differences Between Form 5304-SIMPLE and Form 5305-SIMPLE
When setting up a SIMPLE IRA, employers choose between two IRS model forms:
- Form 5304-SIMPLE: Use this if you want employees to select their own financial institution (e.g., bank or brokerage) for receiving contributions. This offers flexibility but requires coordinating with multiple providers.
- Form 5305-SIMPLE: Opt for this if all contributions go to a single designated financial institution. It’s simpler for administration but limits employee choice.
Both forms establish the plan document and can satisfy employee notification rules, but Form 5304-SIMPLE is ideal for businesses prioritizing employee autonomy in investment choices.
Who Can Use Form 5304-SIMPLE?
This form is tailored for small employers—those with 100 or fewer employees who received at least $5,000 in compensation in the prior year. Self-employed individuals and partnerships can also use it. However, it’s not suitable if the employer maintains another qualified retirement plan (except for certain union employees) or if contributions must go to a designated institution.
Eligible employees typically include those expected to earn at least $5,000 in the current year and who met that threshold in prior years (customizable on the form). Employers can exclude unionized workers under collective bargaining agreements.
How to Establish a SIMPLE IRA Plan Using Form 5304-SIMPLE?
Setting up the plan is straightforward:
- Complete the Form: Fill in Articles I through VII, including eligibility criteria, contribution types (matching or nonelective), and effective date (usually January 1 to October 1 for new plans).
- Notify Employees: Provide a summary description at least 60 days before the annual election period (typically November 2 to December 31). Use the model notification on page 3 of the form.
- Set Up IRAs: Employees establish their own SIMPLE IRAs with chosen institutions.
- Make Contributions: Deduct salary reductions from payroll and add employer contributions by the tax filing deadline (including extensions).
No IRS approval is required, but maintain records for compliance. Recent laws like SECURE 2.0 have expanded options, such as allowing Roth contributions, though the form itself may need updates to reflect these.
Employee Eligibility and Salary Reduction Agreements
Under Article I, employers define eligibility—either all employees or those meeting compensation thresholds (up to $5,000). Article II allows employees to elect salary reductions during a 60-day window before January 1, with optional additional periods (e.g., quarterly).
Elections can’t exceed annual limits and must be implemented promptly. Employees can terminate agreements anytime, but resuming may be restricted.
Contribution Rules and Limits for 2026
Contributions are fully vested immediately. Options include:
- Salary Reduction Contributions: Employees defer pre-tax dollars, up to $17,000 in 2026 ($18,100 for businesses with 25 or fewer employees). Catch-up contributions: $4,000 for ages 50-59 or 64+ ($3,850 for small businesses); $5,250 for ages 60-63.
- Employer Matching: Up to 3% of compensation (minimum 1% in limited years), or
- Nonelective: 2% of compensation for all eligible employees, capped at the annual compensation limit of $360,000 for 2026.
Salary reductions must be deposited within 30 days; employer contributions by tax deadline.
Notification and Disclosure Requirements
Employers must inform employees annually about contribution formulas, election periods, and withdrawal procedures using the model forms on page 3. Failure to notify can result in $50 daily penalties, unless reasonable cause is shown.
Benefits of a SIMPLE IRA Plan
- Tax Advantages: Contributions are tax-deductible for employers; growth is tax-deferred for employees.
- Simplicity: Low setup costs and no discrimination testing.
- Flexibility: Employees control investments; plans can be rolled over after two years.
- Incentives: Potential tax credits for startup costs and saver’s credits for participants.
Common Mistakes to Avoid
- Missing notification deadlines or using outdated forms.
- Exceeding contribution limits or delaying deposits.
- Not updating for law changes, like higher catch-ups under SECURE 2.0.
