Washington State IOLTA Trust Account Management

At a Glance: Washington State attorneys who handle client funds must maintain a compliant IOLTA trust account under RPC 1.15A and RPC 1.15B.

The rules require monthly two-step reconciliations, client-specific ledgers, and seven-year record retention. Interest goes to the Legal Foundation of Washington, not to the firm. If your records aren't audit-ready, this guide shows you exactly what to fix.

If you practice law in Washington State and you handle client funds, trust accounting compliance isn't optional. It's one of the most heavily enforced areas of professional conduct in the state.

The WSBA's Office of Disciplinary Counsel is authorized to examine attorney books and records at random, and those audits resumed in earnest in September 2024 after a pandemic-era pause.

‍Washington attorneys have been disbarred for trust account violations, and bar officials consistently report that misunderstandings around IOLTA rules are among the most common drivers of disciplinary action.

The problem isn't that attorneys don't care. It's that the rules are detailed, the consequences of small errors are serious, and most law school curricula don't cover trust accounting mechanics. This guide covers the Washington-specific IOLTA framework, the core RPC rules, recordkeeping requirements, how to reconcile correctly, and what the random audit program actually looks for.

Purpose and Function of IOLTA Accounts

Washington's IOLTA program serves two equally important purposes: it protects client funds by ensuring they're held in properly structured trust accounts, and it generates interest income for civil legal aid. In 1984, the Washington Supreme Court created the Legal Foundation of Washington (LFW) to administer the program. Interest earned on IOLTA accounts is remitted directly to LFW, which then distributes those funds to civil legal aid programs across the state.

The IOLTA account sits at the center of a lawyer's fiduciary obligations. When a client pays a retainer, a settlement is deposited, or escrow funds land in your hands, those dollars do not belong to your firm. They belong to your client. The trust account is the mechanism that keeps those funds separate, safe, and trackable at all times.

Key Requirements

Washington State's IOLTA rules are detailed enough that a surface-level read leaves room for costly assumptions. The requirements below cover the mechanics that actually matter in practice.

That includes which accounts qualify, how they need to be titled, which banks are authorized to hold them, and what you need to file each year to stay in good standing with the WSBA. None of it is especially complex, but each piece has a specific compliance implication worth understanding before you set anything up.

Mandatory Participation

If you handle client funds, you must maintain an IOLTA or individual interest-bearing trust account. There are no exceptions for firm size, practice area, or frequency.

‍RPC 1.15A(c)(1) requires a lawyer to deposit and hold in a trust account any funds belonging to a client or third person received in connection with a representation. Earned fees are not client funds. Everything else, including advance fee deposits, settlement proceeds, and client overpayments, likely is.

Eligible Financial Institutions

Not every bank qualifies. Only those financial institutions authorized by the Legal Foundation of Washington are eligible to offer IOLTA accounts to lawyers.

The LFW maintains the list of approved institutions, and your bank must have a current Overdraft Notification Agreement on file with them under ELC 15.4. If your bank isn't on the list, it can apply for authorization through LFW. The WSBA website links directly to the LFW's list of authorized financial institutions.

Account Titling and Tax ID

Your IOLTA account must be clearly identified as a client trust account and must use the LFW's tax identification number: 91-1263533. All pooled IOLTA accounts in the State use this same taxpayer ID number.

The bank uses this number to automatically remit interest to LFW. You don't have to track or transfer the interest yourself, but you do need to confirm the account is set up correctly at the outset.

Annual Trust Account Declaration

Each active Washington-licensed legal professional must file a Trust Account Declaration annually during the license renewal process.

‍It isn't sufficient to indicate there has been no change from the prior year; the rules require each active licensed legal professional to file a current and complete declaration. You only report currently open accounts, not closed ones.

Core Legal Framework: RPC 1.15A and RPC 1.15B

RPC 1.15A and 1.15B are where Washington's trust accounting obligations get specific. Together, they define the fiduciary standard attorneys must meet, spell out exactly what records need to be kept, and set the retention timeline that applies long after a matter closes.

Below we cover what each rule actually requires and where the practical compliance pressure tends to show up.

What Does RPC 1.15A Actually Require?

RPC 1.15A is the foundational rule governing trust account management for attorneys here. It establishes the fiduciary standard for safeguarding client property, prohibits commingling, requires prompt disbursement of client funds, and sets out the basic structure for proper trust account maintenance. The rule also addresses what happens when funds are disputed, unidentified, or belong to third parties.

Under RPC 1.15A, a trust account must be interest-bearing and set up under the LFW's tax ID so that interest is automatically forwarded to LFW. Commingling personal or firm funds with client funds is expressly prohibited. You may deposit a minimal amount of firm funds to cover bank service charges, but that's the only exception.

What Does RPC 1.15B Require for Records?

RPC 1.15B is the recordkeeping companion to RPC 1.15A. It specifies exactly what written records you must maintain. At a minimum, RPC 1.15B requires a check register for each trust account, individual client ledgers for each client matter, copies of all receipts and disbursement instruments, and monthly reconciliation reports.

All of these records must be preserved. The retention requirement is seven years. That means if a client matter closed in 2018, you should still have the complete trust account history for it today.

What Goes In (and What Stays Out) of Your Trust Account

The IOLTA account has a narrow purpose: holding client funds until they're properly disbursed or earned.

What makes this section worth reading carefully is that the line between what belongs in trust and what doesn't isn't always intuitive, and the consequences of getting it wrong, particularly around commingling, sit at the serious end of WA's disciplinary spectrum.

What Funds Must Be Deposited?

Client funds are the only funds that belong in an IOLTA account. This includes advance fee deposits (retainers held before work is completed), settlement proceeds, escrow funds, and any money you're holding on behalf of a third party in connection with your representation. Earned fees do not belong in trust. Once a fee is earned, it must be withdrawn promptly to your operating account.

The decision about whether to use a pooled IOLTA or an individual interest-bearing account for a specific client depends on a practical analysis: can the funds realistically earn net interest for the client after accounting for the cost of maintaining a separate account?

If the answer is no, IOLTA is correct. If the funds are large enough or held long enough to generate meaningful net interest for the client, an individual interest-bearing account is required instead.

What About Commingling?

Commingling is one of the most serious violations in trust accounting. You should never deposit client money in your personal or firm's general account. Likewise, never deposit firm funds into the client trust account, except for a minimal amount if needed to cover bank service charges.

Commingling is flagged as a grave ethical error under and it's one of the most common findings in both random audits and disciplinary investigations.

Reconciling Your IOLTA Account

WA's IOLTA reconciliation requirement is a monthly two-step process under RPC 1.15A(h)(6). First, you reconcile your checkbook register to your bank statement to confirm what's actually in the account. Second, you add up all client ledger balances and confirm they equal your reconciled checkbook register balance. Both steps must be documented in writing each month.

This two-step process is sometimes called a "three-way reconciliation" in other jurisdictions because it matches three figures: the bank statement balance, the firm's check register balance, and the sum of all individual client ledger balances. All three must agree. If those records don't match, the IOLTA account is out of compliance, and even experienced firms can encounter this problem.

The WSBA provides a free fillable PDF form, the Monthly Reconciliation and Review Report, that you can use to complete and document this process. You can also use Excel, legal practice management software, or any other method as long as the output shows the three-way comparison clearly.

Before you dig into the reconciliation mechanics, it helps to see what a complete example report package actually looks like. This video walks through a full set of example IOLTA reconciliation reports. We strongly encourage every attorney to review it. Most state bar guides explain the process in narrative form, but seeing an actual completed report set makes the requirements click immediately.

WSBA's Random Audit Program: What You Need to Know

Yes. Under Rule 15.1(a) of Washington's Rules for Enforcement of Lawyer Conduct, the Office of Disciplinary Counsel is authorized to examine the books and records of any lawyer or law firm selected at random to determine whether they're complying with RPC 1.15A and RPC 1.15B. This was one of the first states in the country to authorize random trust account audits, having implemented the program in 1977.

The random audit program paused during COVID-19 due to staffing constraints, but by September 2024 it resumed with a fresh selection of attorney trust accounts. The Audit Department now aims to complete approximately 60 audits per year from a pool of roughly 35,000 licensed lawyers. The process requires attorneys to produce two months of bank and bookkeeping records electronically.

The program is designed to be educational, not punitive in most cases. But if your records aren't in order when you're selected, it can quickly become something more serious. IOLTA audits are commonly triggered by red flags including failure to reconcile monthly, negative client trust balances, overdrafts, missing reconciliation records, and client complaints.

Proper Management of Your IOLTA Accounts

Good trust account management isn't just about following rules. It protects your clients, your license, and your firm's reputation. Here are the practices that matter most:

• ‍Maintain separate client ledgers. Every client whose funds are in your trust account needs their own ledger showing every deposit, disbursement, and running balance for their matter. Commingling client funds at the ledger level, even when the bank account is technically separate, creates an audit finding.Reconcile every month, without exception.
• Reconcile every month, without exception. WA requires monthly reconciliation. Not quarterly. Not "when you get to it." Set a recurring calendar reminder for the first week of each month and document the completed reconciliation in writing.Keep records for seven years.
• Keep records for seven years. Trust account records, including bank statements, client ledgers, the check register, deposit slips, and reconciliation reports, must all be retained for seven years after the end of the representation.Report overdrafts immediately.
• Report overdrafts immediately. Banks are required to report trust account overdrafts to the WSBA. If a trust account is overdrawn or a check is presented against insufficient funds, a lawyer must report the overdraft and provide a full explanation to Disciplinary Counsel. An overdraft, even an accidental one, can trigger a grievance investigation.Use approved software and tools.
• Use approved software and tools. Practice management platforms like Clio, MyCase, and others that integrate with law firm bookkeeping systems can streamline reconciliation and reduce the risk of manual errors. The WSBA also provides Excel check register and client ledger templates on its website.

Frequently Asked Questions

The questions below cover what WA attorneys ask most often about trust account setup, recordkeeping, and oversight. Some answers are straightforward; others carry compliance implications that aren't obvious from reading the rules alone.

If your situation falls outside what's covered here, the WSBA Ethics Line is the right next call.

Does every WA attorney need an IOLTA account?

Not every attorney, but any attorney who handles client funds does. If you receive advance fee deposits, settlement proceeds, escrow funds, or other money that belongs to a client or third party in connection with your practice, you need a trust account. If you receive only earned fees, you likely don't. When in doubt, review RPC 1.15A(c)(1) or call the WSBA Ethics Line at 206-727-8284.

How often is trust account reconciliation required?

Monthly. RPC 1.15A(h)(6) requires attorneys to reconcile trust account records on a monthly basis. The reconciliation is a two-step process: first, match your check register to the bank statement; second, confirm the sum of all client ledger balances equals your reconciled register balance. The WSBA provides a free fillable form to document this process each month.

Where does the interest on my IOLTA account go?

The interest goes to the Legal Foundation of Washington (LFW), a nonprofit independent of the WSBA. LFW distributes those funds to civil legal aid programs across the State. The interest never goes to your firm, and it should not be credited to any individual client ledger. Your bank handles the remittance automatically once the account is correctly set up with the LFW's tax ID number (91-1263533).

Can the WSBA audit my trust account without advance notice?

Yes. Under ELC 15.1(a), the Office of Disciplinary Counsel can select any lawyer or law firm at random for a trust account compliance examination. Washington was one of the first states to authorize random trust account audits, and the program resumed in September 2024 after a COVID-era pause. The Audit Department typically requires you to produce two months of bank and bookkeeping records electronically.

How long do I need to keep trust account records?

WA requires trust account records to be retained for seven years after the end of the representation. This includes bank statements, the check register, individual client ledgers, deposit slips, canceled checks, and monthly reconciliation reports.

‍Incomplete records create a presumption of improper handling, and reconstruction after receiving an audit notice is rarely successful. Organize records from the start of every matter, not retroactively.

Keep Your Trust Accounts Clean With Law Firm Velocity

WA's IOLTA framework isn't especially complicated once you understand what it requires. The rules center on three obligations: keep client funds separate, document every transaction in detailed records, and reconcile monthly. When those three things are done consistently, your firm is in solid shape. When any one of them slips, problems follow fast.

The random audit program is active again. It's not designed to trap attorneys, but it will expose recordkeeping gaps quickly. The best time to clean up your trust accounting process is before you receive an audit notice, not after.
