IOLTA trust accounting explained (and how to get reconciliation right)
What IOLTA is, the three-way reconciliation every state bar requires, and the most common audit-trigger mistakes solo and small firms make.
What IOLTA stands for
IOLTA is "Interest On Lawyers' Trust Accounts." Every U.S. state requires attorneys who hold client funds (retainers, settlement proceeds, deposits) to keep those funds in a separate, interest-bearing trust account. The interest goes to the state bar foundation to fund legal-aid programs, not to the attorney or the client.
Three-way reconciliation: the gold standard
Every month, three numbers must match exactly: (1) the sum of all client sub-ledger balances, (2) the firm's trust journal total, (3) the bank statement balance. If any of the three diverges, the firm has either a bookkeeping error or a compliance problem.
State bars audit randomly and after client complaints. A failed reconciliation is one of the top three reasons for license suspension.
The rules state bars actually enforce
No commingling: never combine personal or operating funds with client funds. Even temporarily.
No drawing on uncollected funds: a client check that hasn't cleared cannot be disbursed against. This catches a lot of small firms when wires bounce.
Separate sub-ledger per matter: aggregate balance is not enough. You must track each client's share inside the pool.
Earned-fee transfers in writing: you can move retainer money out of trust as fees are earned, but only with a contemporaneous billing record.
Common audit triggers
Negative client sub-balance: this NEVER happens correctly. It means you disbursed more than the client had on deposit. Fix immediately and document.
Bank fees on the IOLTA account: most states require fees come out of the operating account, not the trust account. Banks misroute these all the time.
Round-numbered reconciliation: the bank statement total ending in a clean .00 every month is a red flag for tampering.
How software makes this easier
Advottic Counsel ships per-matter sub-ledgers, three-way reconciliation reports, and an auto-flag for negative client balances. Other practice management tools that handle IOLTA include Clio (separate Trust module), CosmoLex, and Smokeball.
Whatever tool you pick, do not run trust accounting in QuickBooks. QuickBooks has no concept of a per-matter sub-ledger and the workarounds break down at scale.
Frequently asked questions
How often should I reconcile my IOLTA?
Monthly, minimum. Quarterly reconciliation is the legal floor in most states; monthly catches errors before they compound.What happens if my IOLTA is short?
A shortfall is a fiduciary breach. You report the discrepancy to your state bar, fund the difference from operating, and document the cause. Failure to report is far worse than the original mistake.
