Both IOLTA accounts and regular trust accounts hold client funds that don’t belong to your law firm. The difference comes down to how interest is handled and which clients’ money goes where.

IOLTA stands for Interest on Lawyer Trust Account. It’s a pooled account where you hold small amounts of client funds or funds that will only be held for a short time. The interest earned on an IOLTA doesn’t go to any individual client. Instead, it goes to support legal aid programs across California. This works because individually, these small or short-term deposits wouldn’t generate meaningful interest for any single client. Pooled together, they fund access to justice programs without affecting your clients.

A regular client trust account is set up when you hold a substantial amount for a specific client over a longer period. Because those funds will earn meaningful interest, that interest belongs to the client. Their funds need to stay separate from the pooled IOLTA so you can track and pay out the interest they’ve earned, minus any bank fees and required tax reporting.

California’s rule is practical. If client funds will earn interest that exceeds the administrative costs of maintaining a separate account, those funds should go into their own trust account. If the interest wouldn’t exceed those costs, the funds belong in your IOLTA. Most retainers, settlement advances, and short-term client funds go into your IOLTA. Large estate funds, real estate proceeds held for extended periods, or substantial settlement amounts waiting for dispute resolution might need their own accounts.

The bookkeeping requirements are similar for both. You need to track every dollar by client matter, reconcile monthly, and maintain detailed records of all deposits and disbursements. The California State Bar can audit your trust accounts at any time, and commingling or record-keeping failures can lead to disciplinary action.

Where it gets complicated is the day-to-day tracking in your IOLTA. Even though it’s a single pooled account at the bank, your books need to show exactly which funds belong to which client. Every deposit and withdrawal must be documented and tied to a specific matter. This is where many firms run into trouble. The bank statement shows one balance, but your records need to show dozens of individual client balances that add up to that total.

Law firm trust accounting requires integrating your practice management software with your accounting system so nothing falls through the cracks. Clio paired with QuickBooks is the standard setup for most small firms, but it needs proper configuration to handle trust accounting correctly.

If you’re managing client trust funds and unsure whether your current setup meets State Bar requirements, working with Los Angeles QuickBooks bookkeepers who understand legal accounting can prevent compliance problems before they start. Getting caught with sloppy trust records isn’t just an administrative headache. It can result in suspension or disbarment.
