IRS Form 5305-S – In today’s dynamic financial landscape, planning for retirement is essential for both employees and employers. One effective tool for small businesses is the Savings Incentive Match Plan for Employees (SIMPLE) IRA, which allows easy contributions toward retirement. At the heart of setting up such a plan is IRS Form 5305-S, the model agreement for a SIMPLE Individual Retirement Trust Account. This form helps establish a trust-based retirement account that complies with federal tax laws, offering tax advantages and simplicity for participants.
Whether you’re an employer looking to provide retirement benefits or an individual setting up your own account, this SEO-optimized guide covers everything you need to know about IRS Form 5305-S. We’ll explore its purpose, eligibility, completion process, key provisions, and more, drawing from official IRS resources to ensure accuracy and relevance.
What Is IRS Form 5305-S?
IRS Form 5305-S is a model trust account agreement designed to meet the requirements of Internal Revenue Code (IRC) sections 408(a) and 408(p). It serves as a template for creating a SIMPLE IRA trust account, which is part of a SIMPLE IRA plan offered by employers with 100 or fewer employees. Unlike more complex retirement plans, SIMPLE IRAs are straightforward, with employer contributions matched to employee salary deferrals.
This form is not filed with the IRS but is kept for record-keeping purposes. It’s specifically for trust accounts, distinguishing it from custodial accounts (which use Form 5305-SA). The latest revision of Form 5305-S is from April 2017, and it remains the current version as of 2026. You can download the official PDF directly from the IRS website at https://www.irs.gov/pub/irs-pdf/f5305s.pdf.
Purpose of Form 5305-S
The primary purpose of IRS Form 5305-S is to establish a SIMPLE IRA trust account in the United States for the exclusive benefit of the participant and their beneficiaries. This account receives employer contributions under a SIMPLE IRA plan, providing retirement income and potential support for beneficiaries after the participant’s death.
Key objectives include:
- Ensuring compliance with IRC sections for tax-deferred growth.
- Allowing transfers or rollovers from other eligible retirement plans after a two-year participation period.
- Prohibiting certain investments, like life insurance or collectibles (with exceptions for specific precious metals), to maintain the account’s integrity.
SIMPLE IRAs are ideal for small businesses because they require minimal administrative effort compared to 401(k) plans. Employers must use either Form 5304-SIMPLE or Form 5305-SIMPLE to set up the overall plan, with Form 5305-S handling the individual trust account setup.
Who Should Use IRS Form 5305-S?
This form is intended for:
- Participants: Individuals eligible under their employer’s SIMPLE IRA plan, including self-employed persons.
- Trustees: Qualified financial institutions, such as banks or savings and loan associations under IRC section 408(n), or IRS-approved entities.
- Employers: Small businesses establishing SIMPLE IRAs for employees, though the form itself is executed between the participant and trustee.
Eligibility for a SIMPLE IRA plan requires the employer to have 100 or fewer employees earning at least $5,000 in the prior year. Employees must have earned at least $5,000 in any two prior years and expect to earn that amount in the current year. Note that SIMPLE IRAs cannot be designated as Roth IRAs, and contributions are limited to cash from employers or eligible rollovers.
If you’re transferring from another SIMPLE IRA, check the “transfer SIMPLE IRA” box on the form. For amendments to an existing agreement, indicate that as well.
How to Fill Out IRS Form 5305-S?
Completing Form 5305-S is relatively simple, but accuracy is crucial for compliance. Here’s a step-by-step guide:
- Participant Information: Enter your full name, date of birth, and address. Check boxes if this is a transfer SIMPLE IRA or an amendment.
- Trustee Details: Provide the trustee’s name and address or principal place of business.
- Review Articles I-VII: These are pre-written and outline the agreement’s core terms. Do not alter them, as they have been reviewed by the IRS.
- Article VIII (Additional Provisions): Add any extra terms here, such as investment powers or fees, but ensure they comply with state law and IRC. If none, draw a line through it.
- Signatures: The participant (or authorized representative) and trustee must sign and date. A witness may be required in some cases.
- Disclosure: The trustee must provide a disclosure statement per Regulations section 1.408-6.
Do not file the completed form with the IRS—retain it with your records. For detailed guidance, refer to IRS Publication 560 (Retirement Plans for Small Business) and Publications 590-A and 590-B (Individual Retirement Arrangements).
Key Sections and Articles of Form 5305-S
The form is structured around eight articles, with the first seven being IRS-reviewed models:
- Article I (Contributions): Limits contributions to cash from employers under the SIMPLE plan or rollovers from eligible plans after two years. No other contributions allowed.
- Article II (Nonforfeitable Interest): Ensures the participant’s balance is fully vested.
- Article III (Investments): Prohibits life insurance, commingling of assets (except in common funds), and most collectibles.
- Article IV (Distributions): Details required minimum distributions (RMDs) starting at age 72 (as updated in recent laws), using life expectancy tables from Regulations section 1.401(a)(9)-9. Includes rules for post-death distributions.

- Article VI (Controlling Provisions): States that Articles I-III govern and invalidates inconsistent additions.

These ensure the account adheres to tax rules, with RMDs calculated based on account value divided by life expectancy factors.
