Most explanations of IOLTA come from a state program describing its own fund or a bank describing its own product. Neither answers what a firm owner is actually asking: what this account is, why the interest goes somewhere other than my client, and how I know which client’s money belongs in it.
Key takeaways
- IOLTA stands for Interest on Lawyers’ Trust Accounts. It is a pooled client trust account whose interest is paid to a state program that funds civil legal aid.
- Which account a client’s money belongs in is not a preference. It is a net return test: funds nominal in amount or held for a short period go into IOLTA.
- The structure exists because of a 1980 federal banking change. Florida launched the first program in 1981, and every state and the District of Columbia followed.
- The Supreme Court settled the constitutional question in 2003: no Just Compensation Clause violation, because a client whose funds could not earn net interest loses nothing.
- FDIC coverage can pass through to each client at $250,000, but only if the bank’s records identify who owns the money.
What an IOLTA account actually is
An IOLTA account is a client trust account with one distinguishing feature: it is pooled, and the interest it earns does not belong to any of the clients whose money is in it. Lawyers routinely hold funds belonging to someone else, and when those amounts are small or held only briefly, the National Association of IOLTA Programs describes the practice plainly. The funds go into a pooled account, and the income generated on the pooled funds is used for civil legal aid and other programs that support access to justice for low-income people.
The mechanics are the same everywhere. The lawyer deposits qualifying client funds at an eligible financial institution, the bank remits the interest to the state’s IOLTA program, and the program grants that money to nonprofits providing free civil legal services. In Texas, the interest goes to the Texas Access to Justice Foundation. North Carolina’s program makes the economics explicit for the participating firm: funding provided from IOLTA accounts comes at no cost to the lawyer, law office, or client. You are not donating. You are directing interest that, on these balances, would not have reached the client anyway.
Everything else is ordinary trust accounting. The duties to segregate funds, keep per-client records, and reconcile on a schedule apply exactly as they do to any client trust account, which is the subject of our guide to trust accounting compliance. IOLTA is a routing decision layered on top of those duties, not a substitute for them.
Why the interest goes to legal aid and not to your client
This is the part almost no explainer covers, and it is what makes the rule make sense. Before 1980, lawyer trust accounts could not pay interest at all, so the question of who owned that interest never arose. Then, as the Supreme Court recounted in Brown v. Legal Foundation of Washington, Congress in 1980 authorized federally insured banks to pay interest on a limited category of demand deposits referred to as NOW accounts. A pool of interest existed that had not existed the year before.
Florida moved first. The Court’s opinion records that Florida adopted the first IOLTA program in 1981, authorizing the use of NOW accounts for the deposit of client funds and providing that all of the interest on such accounts be used for charitable purposes. Adoption spread from there through legislatures and state supreme courts, and the Court’s 2003 summary is unambiguous: every state in the nation and the District of Columbia have followed Florida’s lead and adopted an IOLTA program. Programs now operate in all United States jurisdictions, including Puerto Rico and the U.S. Virgin Islands.
The constitutional objection was that taking interest generated by a client’s money is a taking of the client’s property. The Court’s reasoning turned on remedy rather than ownership: compensation for a taking is measured by the owner’s pecuniary loss, and that loss is zero whenever the rule is followed, because funds placed in IOLTA are by definition funds that could not have produced net interest for the client. That is why the eligibility test below is not administrative trivia. It is what keeps the structure lawful.
Which client funds belong in an IOLTA account
The test is economic, not categorical. Washington’s Rule of Professional Conduct 1.15A states it as clearly as any jurisdiction: when client or third-person funds will not produce a positive net return, because the funds are nominal in amount or expected to be held for a short period of time, the funds must be placed in a pooled interest-bearing trust account known as an Interest on Lawyer’s Trust Account or IOLTA. Texas applies the same standard.
The Massachusetts IOLTA Committee gives the everyday examples: settlement checks, retainers and other fees advanced for services not yet performed, and funds related to real estate transactions. For most small firms that covers nearly everything passing through the trust account in a year.
The reverse case has its own rule. Funds that will produce a positive net return must go into a non-IOLTA trust account, either a separate interest-bearing account for that client with the interest paid to the client, or a pooled account with sub-accounting that computes and pays each client’s interest individually. Washington’s rule adds one exception: the client can ask that the funds go into IOLTA anyway.
The three factors that settle the question
Because the standard is a net return, the analysis has a specific shape. Washington’s rule directs the lawyer to consider only whether the funds will produce a positive net return to the client, as determined by three factors. First, the amount of interest the funds would earn based on the current rate of interest and the expected period of deposit. Second, the cost of establishing and administering the account, including the cost of the lawyer’s services and of preparing any tax reports required for interest accruing to the client’s benefit. Third, the capability of financial institutions to calculate and pay interest to individual clients.
Two things follow. Your own time is a cost in the calculation, not a soft consideration, which is why a five-figure balance held for two weeks usually still belongs in IOLTA. And the answer moves with prevailing rates, so run the analysis at intake for anything unusually large or unusually long, and document the reasoning in the file.
| Pooled IOLTA account | Client-specific interest-bearing account | |
|---|---|---|
| When it applies | Funds that will not produce a positive net return, because they are nominal in amount or held for a short period | Funds that will produce a positive net return, unless the client asks for IOLTA instead |
| Typical examples | Advance fees for work not yet performed, settlement checks passing through, real estate transaction funds | A balance large enough, or held long enough, that interest would exceed the cost of running the account |
| Who receives the interest | The state IOLTA program, which grants it to civil legal aid organizations | The individual client or third person whose funds they are |
| What you still owe | A ledger per client, periodic reconciliation, no disbursement beyond that client’s balance | The same records, plus interest computation and any required tax reporting |
Setting up an IOLTA account without a false start
Opening the account is straightforward, but three details cause most of the avoidable trouble.
Start with an eligible institution, because not every bank qualifies. Participation runs through the state program, and eligibility usually carries a rate obligation. California’s framework shows how specific this can be: financial institutions volunteer to provide IOLTA accounts under Business and Professions Code section 6212, and leadership institutions provide the highest interest rate, based on 68 percent of the federal funds rate, or 0.68 percent, whichever is higher. North Carolina likewise directs lawyers to institutions that work with the program to set the highest rates possible. Ask your state program for its list first.
Then get the titling right, because it is what makes the account insurable. The FDIC treats a lawyer or law firm holding client funds in an IOLTA as a pass-through arrangement, meaning deposits are insured to the same extent as if they had been deposited in the name of the underlying owners. That treatment is conditional: the relationship must be expressly disclosed in the bank’s deposit account records, often through titling indicating the account is held as agent or for the benefit of others, and each owner’s identity and ownership interest must be ascertainable from those records.
Finally, open the per-client ledger the same day you open the account, not the first time you need one. This is also the moment to keep your operating account genuinely separate, a point covered in the two-bank-accounts section of our guide to starting a law firm. The one narrow exception is that you may deposit your own funds to pay bank charges, in an amount reasonably sufficient for that purpose.
What IOLTA does not change about your duties
Because the interest leaves automatically, IOLTA can feel like a set-and-forget arrangement. It is not. The safekeeping rule still governs every dollar in it. A lawyer must not use, convert, borrow, or pledge client property for the lawyer’s own use. Withdrawals must be made only to a named payee and not to cash. Disbursements on behalf of a client may not exceed that client’s funds on deposit, and one client’s money must never be used on behalf of anyone else. Funds should not be disbursed until deposits have cleared the banking process.
Reconciliation is the control that catches failures of all four. Washington requires trust account records to be reconciled as often as bank statements are generated, or at least quarterly, matching the check register to the bank statement and to the combined total of all client ledgers. Monthly is the better habit, and the errors it catches are covered in our trust accounting guide. How the money arrives matters too, since your fee agreement determines what lands in trust and when it may leave, the subject of our explainer on how attorney retainers work. Confirm your own state’s requirements, since rule numbering, reconciliation frequency, and IOLTA participation all vary.
Where the interest goes, and why the number moves
It helps to see the scale of what these balances produce. North Carolina’s program reports having awarded more than $134 million to organizations providing legal aid. Pennsylvania’s IOLTA Board reported total grant expenses of $36,074,558 for the 2024 to 2025 fiscal year, and it is candid about what drives that figure: in 2025, revenue from interest earned on IOLTA accounts matched the high-water mark set in 2024 because interest rates stayed high. The board raised grants by 30 percent that year and moved the remainder into a designated stabilization fund, expressly because revenues are likely to decline as rates fall.
That volatility is structural. When the eligible-institution rate is pegged to a percentage of the federal funds rate, as California’s is, the money available for legal aid rises and falls with monetary policy rather than with anything the profession does. Your obligation is narrower and steadier: route the right funds to the right account, keep clean records, and reconcile.
Trust accounting is one of the systems that quietly decides whether a firm is durable, alongside how it prices work, how it answers the phone, and how it gets paid. The Spine program treats finance and operations as two of seven connected systems, and the five-minute assessment will show you which of the seven to work on first.
Frequently asked questions
IOLTA stands for Interest on Lawyers’ Trust Accounts. Qualifying client funds are pooled in an interest-bearing trust account, and the interest is paid to a state IOLTA program rather than to individual clients. The program grants that income to organizations providing civil legal aid and other access-to-justice services.
The clients and third persons whose funds are on deposit own the money. The lawyer holds it as a custodian, must keep it separate from the firm’s own property, and may not use, convert, borrow, or pledge it for the firm’s own use. The only firm money permitted in the account is an amount reasonably sufficient to pay bank charges.
Not quite. Escrow is a role, while IOLTA is an account type. Washington’s safekeeping rule applies both to client property held in a representation and to escrow funds a lawyer holds incident to a real estate or personal property closing. Whether those funds sit in a pooled IOLTA account or a client-specific interest-bearing account is decided by the same net return test as any other trust money.
No. Pooling is the point, and it is what makes the interest worth collecting. What you do need is a separate ledger for each client, because disbursements on behalf of a client may not exceed that client’s funds on deposit, and because reconciliation requires the combined total of all client ledgers to agree with the account balance.
It can be, on a pass-through basis. The FDIC lists a lawyer or law firm holding client funds in an IOLTA among its pass-through arrangements, where deposits are insured as if held in the name of the underlying owners, subject to the standard maximum of $250,000 per depositor, per insured bank, for each ownership category. That treatment requires the relationship to be disclosed in the bank’s records and each owner’s identity and interest to be ascertainable.
