Michigan IOLTA Trust Account: A Complete Compliance Guide for Attorneys

TL;DR: Michigan attorneys who handle client funds must maintain a compliant IOLTA trust account under MRPC 1.15 and 1.15A. The rules require using an approved financial institution, maintaining individual client ledgers, performing monthly three-way reconciliations, and keeping records for at least five years. Violations are the leading cause of attorney discipline in Michigan. This guide breaks down exactly what you need to know and do to stay compliant.

If you've ever lost sleep over whether your IOLTA account would hold up to scrutiny, you're not alone. Trust accounting is one of the most regulated areas of law practice in Michigan, and it's the number one source of bar complaints. According to data from the Michigan Attorney Discipline Board, nearly half of all attorneys disciplined in a recent year had violated trust account rules under MRPC 1.15 or 1.15A. That's not a coincidence.

Michigan IOLTA rules are designed to protect clients, and they leave little room for error. Whether you're opening your first trust account or you're a managing partner trying to tighten your firm's compliance systems, this guide covers what the rules actually require, how the oversight system works, and where most firms run into avoidable risk.

Purpose and Function of Michigan IOLTA Accounts

The Michigan IOLTA program was created by the Michigan Supreme Court in 1990. It requires attorneys to deposit nominal or short-term client funds into a pooled, interest-bearing trust account. The interest doesn't go to the lawyer or the client. It goes to the Michigan State Bar Foundation (MSBF), which funds civil legal aid for low-income households across the state.

Since the program launched, Michigan financial institutions and lawyers have collectively distributed over $31 million to law-related charitable projects. Those funds support nonprofits that protect people from domestic violence, assist veterans with healthcare access, and ensure child support is enforced. Participating in IOLTA isn't just a compliance checkbox. It directly connects your firm to access-to-justice work happening in your community.

What Is an IOLTA Account and When Do You Need One?

An IOLTA account is a pooled, interest-bearing trust account used to hold client funds that are either too small in amount or held for too short a period to generate net interest for the individual client. Once a lawyer makes a good-faith judgment at the outset that funds qualify as nominal or short-term, those funds must go into the IOLTA account, and the interest goes to the MSBF.

If a client's funds are large enough or held long enough to earn meaningful interest after bank fees, you're required to open a separate, non-IOLTA trust account for that specific client. The interest in that case would benefit the client directly. Michigan's rules leave the initial determination to your good-faith judgment, and that determination is not reviewable by a disciplinary body as long as you applied the right criteria. You should revisit the classification if circumstances change.

For most everyday situations, such as retainers, settlement proceeds held briefly, or cost advances, IOLTA is the correct account.

Core Legal Framework: Michigan's Trust Account Rules

Michigan's IOLTA requirements are primarily built on MRPC 1.15 (Safekeeping Property) and MRPC 1.15A (Trust Account Overdraft Notification), both adopted by the Michigan Supreme Court. Together, they create a comprehensive framework governing how client funds must be deposited, tracked, reconciled, and reported.

The Michigan Supreme Court has also been reviewing proposed updates to Rules 1.15, 1.15A, and proposed new rules 1.15B and 1.15C to modernize the framework and address gaps, particularly around advance fees and recordkeeping duties. Attorneys should monitor proposed amendments from the Michigan Supreme Court as these continue to develop.

MRPC 1.15: The Foundational Duty

MRPC 1.15 establishes the core fiduciary obligation every Michigan attorney has when handling client or third-party funds. You must keep those funds completely separate from your personal and business accounts. The rule prohibits misappropriation, conversion, and commingling, even when no harm results. A technical violation is still a violation. The rule also requires prompt notification when client funds are received and prompt delivery once those funds are disbursed.

MRPC 1.15A: The TAON Rule

MRPC 1.15A creates Michigan's Trust Account Overdraft Notification (TAON) system. Under this rule, financial institutions must obtain approval from the State Bar of Michigan before they can serve as a depository for any attorney trust account. To get that approval, banks sign an agreement to notify both the account holder and the Michigan Attorney Grievance Commission (AGC) any time the trust account is overdrawn or a check is dishonored. That automatic notification is what triggers most AGC investigations.

Setting Up a Michigan IOLTA Account

How Do You Open a Compliant IOLTA Account in Michigan?

Opening a Michigan IOLTA account requires choosing an approved financial institution, completing the correct enrollment form, using the MSBF's tax identification number, and establishing your internal ledger structure before you accept any client funds. Skipping any of these steps creates a compliance gap from day one.

Here are the required steps:

Step 1: Choose an Eligible Financial Institution. Under MRPC 1.15A, you can only maintain an attorney trust account at a financial institution approved by the State Bar of Michigan. These institutions have signed the TAON overdraft notification agreement. The MSBF publishes a current list of eligible institutions. You should verify eligibility before opening the account, not after.

Step 2: Complete the "Notice to Eligible Financial Institution" Form. This is the form that officially enrolls your account in the IOLTA program. You can download it from the MSBF website. You'll complete a separate form for each IOLTA account, though most firms only need one. The form instructs the bank to set up an interest-bearing account, use the MSBF's tax identification number (38-1459016) for interest reporting, and remit interest directly to the Foundation. After signing, give one copy to the bank, send a second copy to the MSBF, and keep a third copy for your records.

Step 3: Use the MSBF's Tax ID Number. The IOLTA account bears the MSBF's tax ID number (38-1459016), not your firm's. This means no 1099 or W-9 forms are required for the account, and you should not issue them. Using the wrong tax ID creates unnecessary IRS reporting complications and is a common setup error.

Step 4: Title the Account Correctly. The account must be clearly identified as a trust account. Acceptable titles include "Smith & Jones PLLC Client Trust Account" or "Law Office of Jane Doe IOLTA Trust Account." The title must include "Trust" or the IOLTA designation. Improper titling is one of the most commonly flagged issues in trust account reviews.

Step 5: Establish Your Internal Accounting Structure. Before you accept the first dollar of client funds, create a client ledger for every matter and establish your pooled trust ledger. Set your reconciliation schedule. Don't accept client funds into an account that doesn't yet have the supporting bookkeeping infrastructure in place.

What Does Michigan IOLTA Compliance Require Day-to-Day?

What Are Michigan's Ongoing Trust Account Requirements?

Michigan requires monthly three-way reconciliation of your IOLTA account, individual client ledgers for every matter with funds in trust, a minimum five-year record retention period, and immediate reporting of any overdraft or discrepancy. These aren't suggestions. They're enforceable ethical obligations under MRPC 1.15 and 1.15A.

Here's what that looks like in practice:

Three-Way Reconciliation. The gold standard of IOLTA compliance. Every month, you must reconcile three things: (1) the bank statement balance for the trust account, (2) the balance in your pooled trust ledger or accounting system, and (3) the total of all individual client ledgers. All three must agree, after accounting for outstanding checks and deposits in transit. According to guidance from the Michigan State Bar Foundation, monthly reconciliation is best practice for any active firm. When we work with firms on trust accounting services, the first thing we look for is whether reconciliations are being done on time, consistently, and with all three components properly documented.

Individual Client Ledgers. You must maintain a separate ledger for every client with funds in your trust account. Each entry must show the date, amount, a clear description (retainer, settlement deposit, fee transfer), and a running balance. If Client A has $5,000 in trust and Client B has $3,000, your bank balance should be $8,000. No more, no less. Any orphaned funds or negative client balances are a red flag in a disciplinary review.

Record Retention. Michigan requires that complete trust account records be preserved for at least five years after the representation ends. This includes bank statements, deposit slips, canceled checks or images, receipt and disbursement journals, client ledgers, and retainer agreements. A practical tip: default to seven years for all records. Digital storage is inexpensive, and trust account records surface in malpractice claims and fee disputes long after matters close.

Withdrawal Rules. Cash withdrawals from the trust account are prohibited under Michigan rules. Disbursements must have a clearly identified payee, documented purpose, and authorization tied to a specific client matter. Never draw against deposits that haven't cleared. And never use one client's funds to cover another client's expenses, even temporarily.

Signatory Controls. Only licensed attorneys should have signatory authority over IOLTA accounts. Non-attorney staff can assist with bookkeeping, but the attorney must actively supervise and remain accountable for all trust account activity. Document your firm's internal oversight procedures.

The TAON System: How Michigan Monitors Your Trust Account

Michigan uses an automatic overdraft notification system to catch trust account problems early. When your bank detects an overdraft or dishonored check on your trust account, it reports that event directly to the Michigan Attorney Grievance Commission. That report is what kicks off most trust account investigations.

Under MRPC 1.15A, even overdraft protection transfers trigger the notification requirement. The bank reports that the account lacked sufficient funds, even if the overdraft was covered. You can't retroactively fix your way out of the report. A single, clearly documented bank error that you correct immediately is unlikely to result in severe discipline. A pattern of overdrafts, missing records, or unexplained shortfalls will.

If you receive an overdraft notice from the AGC, respond promptly and completely. Prepare your bank statement, reconciliation reports, client ledgers, and a written explanation. Firms that can demonstrate clean records and isolated circumstances fare considerably better than those who can't produce organized documentation on short notice.

The best protection is never needing to respond to an overdraft inquiry at all. Maintain a standing response packet template so you can assemble documentation quickly if it ever becomes necessary.

Oversight and Enforcement in Michigan

Michigan's trust account oversight structure involves several interconnected bodies, each with a distinct role.

Michigan State Bar Foundation (MSBF). The MSBF administers the IOLTA program, maintains the list of eligible financial institutions, manages interest remittance, and provides resources for attorneys and banks. The Foundation also handles refund requests for remittance errors. For any question about eligible institutions, enrollment forms, or how interest is handled, the MSBF is your starting point. Reach them at (517) 346-6400 or at msbf.org.

Attorney Grievance Commission (AGC). The AGC is the enforcement arm of Michigan's attorney discipline system. It receives overdraft notices from banks under TAON, investigates potential misconduct, and brings formal complaints before the Attorney Discipline Board when warranted. The AGC can request reconciliations, ledgers, and supporting records at any time. Failing to cooperate or produce complete records escalates outcomes significantly.

Michigan Attorney Discipline Board (ADB). The ADB is the adjudicative arm of the Michigan Supreme Court for attorney discipline matters. Once the AGC files a formal complaint, the ADB assigns a three-attorney hearing panel to evaluate the charges. Sanctions range from reprimands to suspension to disbarment, depending on the nature and severity of the conduct. Trust account violations, particularly commingling and misappropriation, are treated as serious misconduct. As a Michigan ADB case demonstrates, repeated commingling can result in meaningful suspensions even when no client loses money. Prior disciplinary history is an aggravating factor.

State Bar Ethics Helpline. Michigan attorneys can call the State Bar Ethics Helpline at (877) 558-4760 for a confidential, informal advisory opinion on a prospective ethics question. If you're uncertain about a specific trust account situation, call before you act.

Conclusion

Michigan's IOLTA rules protect clients and the public. They also protect your license. The rules themselves are straightforward: keep client funds separate, document every transaction, reconcile monthly, and use an approved bank. What trips firms up isn't the rules themselves. It's the daily discipline of executing against them, especially in busy firms where the financial work gets pushed aside.

The three things that protect you most are clean records, consistent reconciliation, and an honest response when something goes wrong. If your current processes wouldn't survive an AGC records request today, that's the issue to fix first.

We help firms get their trust accounting right and keep it that way. Schedule a consultation to talk through your current setup, or request an example IOLTA reconciliation so you can see exactly what compliant reporting looks like.

Frequently Asked Questions

1. Is IOLTA participation mandatory for Michigan attorneys?

Yes. Under MRPC 1.15, Michigan attorneys who handle nominal or short-term client funds are required to deposit those funds into an IOLTA account. There is no opt-out. The only exception applies when client funds are large enough and held long enough to earn net interest for the individual client, in which case a separate, non-IOLTA trust account for that client should be used.

2. What happens if my Michigan IOLTA account is overdrawn?

Under Michigan's TAON rule (MRPC 1.15A), your bank is required to notify both you and the Attorney Grievance Commission immediately. The AGC will typically request your reconciliation reports, client ledgers, and bank statements, and may open an investigation. A corrected overdraft does not prevent the report from being filed. Even if the overdraft was a bank error, you must respond with documentation. Repeated overdrafts or incomplete records substantially increase the risk of formal disciplinary proceedings.

3. How long must Michigan attorneys keep IOLTA records?

Michigan rules require a minimum of five years of record retention after the representation ends. This includes bank statements, deposit slips, canceled checks, client ledgers, retainer agreements, and disbursement records. Many practitioners and professional advisors recommend defaulting to seven years, since records can surface in malpractice claims and fee disputes well after formal retention periods expire.

4. What is a three-way IOLTA reconciliation and how often is it required?

A three-way reconciliation is the process of matching three figures: (1) the bank statement balance for your trust account, (2) the balance in your trust account ledger or accounting system, and (3) the total of all individual client ledger balances. All three must agree, after adjusting for outstanding items like uncleared checks. Monthly reconciliation is the expected standard for active Michigan firms and is essential to staying audit-ready. The reconciliation must be documented and retained.

5. Can a non-attorney bookkeeper handle Michigan IOLTA accounting?

Non-attorney staff can assist with the bookkeeping tasks associated with the IOLTA account, including data entry, ledger maintenance, and reconciliation preparation. However, only licensed attorneys should have signatory authority over the account. More importantly, the attorney remains fully responsible for the accuracy and completeness of all trust account records under MRPC 1.15, regardless of who does the day-to-day work. Firms must document their internal oversight and supervision procedures to demonstrate that attorney control is real, not just nominal.
