California IOLTA Account: CTAPP Compliance and Trust Rules

If you practice law in California and handle client money, you need an Interest on Lawyers’ Trust Account (IOLTA) at an eligible bank, registered with the State Bar, for client funds that are too small or held too briefly to earn meaningful net interest for the client. California Business and Professions Code sections 6211 through 6228 and Rule 1.15 of the California Rules of Professional Conduct set the requirements, and the State Bar’s Client Trust Account Protection Program (CTAPP) layers an annual certification on top of them.

Which Client Funds Go Into the IOLTA

The threshold test is whether the client funds are “nominal in amount” or will be held for a “short period of time.” If either is true, the money belongs in the pooled IOLTA account rather than a separate interest-bearing trust account.¹ The reasoning is practical: if the interest a particular deposit would earn gets eaten up by the bank fees and accounting costs needed to track it, pooling makes sense. Interest from the pooled account goes to the State Bar to fund legal aid, not to you and not to the client.

To decide where a given deposit belongs, weigh four things: the amount, how long you expect to hold it, current interest rates, and the cost of administering a separate account. A $500 settlement you plan to distribute in two weeks is a textbook IOLTA deposit. A $200,000 real estate escrow you will hold for 90 days is not; funds large enough and held long enough to generate net interest after accounting costs must go into a separate, individual interest-bearing trust account opened under the client’s taxpayer identification number, so the interest income is reported to the IRS in the client’s name.² There is no bright-line dollar figure or calendar threshold in the statute. The call rests on your professional judgment, and documenting your reasoning is wise.

Choosing an Eligible Financial Institution

Your IOLTA must sit at an “eligible institution,” meaning a bank, savings and loan, or other federally or state-regulated financial institution that carries federal deposit insurance and pays interest or dividends on IOLTA deposits.³ The California Supreme Court can authorize other institutions as well.

Eligible institutions cannot pay IOLTA customers a lower rate than comparable non-IOLTA customers get on the same account type, and they cannot factor the IOLTA designation into the rate. Reasonable bank fees may be deducted from the interest before it is remitted to the State Bar, but no fee or service charge can come out of the client principal in the account.⁴

Opening the Account and Registering With the State Bar

When you open the IOLTA, give the bank the State Bar’s taxpayer identification number, 94-6001385, so the institution remits interest directly to the State Bar rather than to you or the client.⁵ You then have 30 days to register the account through your My State Bar Profile under State Bar Rule 2.2(C).⁶

Starting January 1, 2026, attorneys opening a new trust account must also provide the bank with the State Bar’s “Notice to Financial Institutions” form, which identifies the designated licensee name and State Bar number for the account. If you already hold an existing trust account, you must submit this form to your bank between January 1, 2026, and July 1, 2026. From then on, you have 30 days to update the designated licensee information whenever a designated licensee becomes inactive, loses eligibility to practice, or leaves the firm.⁵

Record-Keeping and Monthly Reconciliation

Rule 1.15 requires detailed records for every dollar passing through the trust account, kept for at least five years after you make the final distribution of the funds.⁷ You need:

An individual client ledger for each client or matter, showing the date, amount, and source of every deposit; the date, amount, payee, and purpose of every disbursement; and the running balance.
An account journal for each bank account, logging every debit and credit, the client it relates to, and the current balance.
Original bank statements and canceled checks for each account.
A written monthly reconciliation comparing the client ledger totals, the account journal, and the bank statement.

The monthly reconciliation is where most problems surface. If your client ledger totals do not match the bank statement after accounting for outstanding items, something is wrong. It is the first thing a compliance reviewer will ask to see, and the single most important safeguard against accidental shortfalls or undetected errors.

You also must notify clients promptly when you receive funds on their behalf. Rule 1.15 sets a 14-day window for that notification, absent good cause for delay.⁷

The Commingling Ban

Rule 1.15(c) flatly prohibits depositing your own money or your firm’s operating funds into a trust account. There are only two exceptions.⁷

First, you may deposit enough of your own money to cover bank service charges on the account. This is a practical necessity because IOLTA account fees cannot come out of client principal.

Second, when a deposit contains funds belonging partly to the client and partly to you (a settlement check that includes your fee, for example), the whole amount goes into the trust account. You then withdraw your portion at the earliest reasonable time after your right to those funds becomes fixed. If the client disputes your share, that disputed portion stays in trust until the disagreement is resolved. Pulling disputed funds out early is one of the fastest ways into disciplinary proceedings.

Flat Fees Paid in Advance

Flat fees are a common point of confusion. Rule 1.15(b) allows you to deposit a flat fee directly into your operating account, but only if you give the client written disclosure that they have the right to require you to hold it in trust until earned and that they are entitled to a refund of any unearned portion. For flat fees over $1,000, the client must sign a written agreement to the operating-account arrangement.⁷ Without those disclosures, the fee goes into trust like any other advance.

Overdrafts Are Reported Automatically

Every bank holding California attorney trust accounts must report any overdraft or insufficient-funds event directly to the State Bar, whether or not it actually honors the check. Holding a California law license is deemed consent to this reporting.⁸

If the bank dishonors a check, it sends the State Bar the standard overdraft notice (usually with a copy of the dishonored check). If the bank covers the overdraft, it still must report the details within five banking days. The bank can charge you a reasonable fee for producing these reports. There is no way to prevent the report, and an overdraft on a trust account will draw scrutiny. Keeping a small cushion of your own funds in the account to cover bank charges helps prevent the timing errors that cause most accidental overdrafts.

Annual CTAPP Compliance

The Client Trust Account Protection Program adds a yearly compliance step during license renewal. You must:

Register all IOLTA and non-IOLTA trust accounts with the State Bar, individually or through your firm.
Complete a self-assessment on your trust account management practices.
Certify that you understand and comply with Rule 1.15.

The 2026 CTAPP reporting deadline is March 30, 2026.⁹ Later phases of the program will include compliance reviews of selected attorneys by a certified public accountant, so treat the self-assessment as a preview of what a full audit would examine.

What Happens If You Don’t Comply

When the CTAPP deadline passed in a recent cycle, more than 1,700 attorneys who failed to complete the reporting requirements received administrative suspensions. Non-compliant attorneys were fined $75 and given a cure period before suspensions took effect, but those who still did not respond lost their active status.

Substantive violations are worse. Reported disciplinary outcomes for trust account mishandling have ranged from one year of actual suspension with additional probation to three years of suspension, depending on the circumstances and whether restitution was made. The California Supreme Court has long treated misappropriation and commingling of client funds as a “gross violation of general moral principles as well as professional ethics” that warrants severe discipline.¹⁰ Deliberate theft from a trust account routinely results in disbarment.

FDIC Pass-Through Coverage for Pooled Funds

Because the IOLTA pools money from multiple clients in a single bank account, each client’s share is separately insured up to $250,000 through the FDIC’s pass-through coverage, as if the client had deposited the money directly, provided three conditions are met:¹¹

The funds actually belong to the client, not to the attorney who opened the account.
The bank’s records show the fiduciary nature of the account (the “Trust Account” label required by Rule 1.15 satisfies this).
Records kept by the bank, the attorney, or another party in the normal course of business identify each client and their ownership interest.

If any of those requirements fails, the FDIC insures the entire account as belonging to the attorney, meaning $250,000 total across all clients combined. The individual client ledgers Rule 1.15 already requires are what satisfies the third condition.

Where the Interest Goes

All interest earned on IOLTA accounts is remitted by the bank directly to the State Bar of California’s Legal Services Trust Fund Program. You have no administrative role in calculating or sending it, and individual clients whose deposits are nominal or short-term do not receive any of it. That is the trade-off at the heart of the IOLTA system: money that would otherwise sit idle funds civil legal services for Californians who cannot afford a lawyer.
