Trust Accounting for Law Firms: A CPA's Guide to Keeping Client Funds Clean
By David Nguyen, CPA · Accounting Fresh CPA Inc. · September 2026

Most attorneys never plan to mishandle client money. They just get busy.

A retainer lands in the operating account, a fee gets pulled before it is earned, or the monthly reconciliation slides for a quarter. In California, those small slips can turn into a State Bar investigation, and "I didn't know" is not a defense.

This guide walks through what trust accounting actually requires, the California rules that govern it, and the simple monthly routine that keeps your firm compliant and audit ready.

What is a client trust account?

A client trust account is a separate bank account that holds money belonging to clients or third parties, not to the firm. Think advance fees for costs, settlement proceeds, and funds held in escrow for a transaction. The money is yours to safeguard, not yours to spend.

There are two main types:

Account typeWhen it is usedWhere the interest goes
IOLTA (pooled)Funds that are small in amount or held for a short timeTo the State Bar's legal services grant program
Non-IOLTA (separate interest-bearing)Funds large enough, or held long enough, to earn net interest for the clientTo the client

The key rule: client money and firm money never mix. Earned fees move out of trust promptly, and firm money stays out, except for a small amount to cover bank charges.

The California rules you need to know

Two sets of rules drive trust compliance in California: Rule 1.15 of the Rules of Professional Conduct and the State Bar's Client Trust Account Protection Program (CTAPP).

Rule 1.15 recordkeeping. Every firm holding client funds must keep:

  • A client ledger for each client, showing every deposit, payment, and running balance
  • An account journal for each trust account
  • Bank statements and cancelled checks
  • A written monthly reconciliation of all three

These records must be kept for five years after the final distribution of funds. Once a client's right to money is fixed and undisputed, holding it more than 45 days creates a presumption of a violation unless there is good cause.

CTAPP annual reporting. Nearly every active California lawyer must, as part of annual license renewal:

  1. Register every IOLTA and non-IOLTA account, with its December 31 balance
  2. Complete a self-assessment of their trust accounting practices
  3. Certify that they understand and comply with the rules on safekeeping client funds

This applies even to lawyers who hold no client money. Starting in 2026, the only exemption is voluntary inactive status for the whole year. The 2026 deadline was March 30, so confirm each year's date on the State Bar's CTAPP page.

The stakes. Missing CTAPP leads to noncompliance fees and, if ignored, administrative inactive enrollment, meaning you cannot practice law until you are reinstated. Lawyers selected for a compliance review must hire a State Bar approved CPA within 30 days and hand over their trust records. Problems found there can escalate to an investigative audit covering three years of activity (CTAPP rules).

Three-way reconciliation, explained

A three-way reconciliation proves that three independent records agree every month:

  1. The adjusted bank balance: the bank statement, adjusted for outstanding checks and deposits in transit
  2. The trust account journal (checkbook) balance: your own running record of the account
  3. The total of all client ledgers: the sum of every individual client's balance

A two-way match (bank to books) is not enough. It can look perfect while one client's balance is negative and another's is overstated, which means one client's money is quietly funding another.

Example: Smith & Lee LLP, March 31

RecordAmount
Bank statement balance$52,400
Less outstanding check #1043($2,400)
Adjusted bank balance$50,000
Trust journal balance$50,000
Client Garcia ledger$30,000
Client Patel ledger$15,000
Client Wong ledger$5,000
Total client ledgers$50,000

All three totals agree, and no client ledger is negative. That is a clean month. If any number is off, find and fix the cause before the next month closes, then document what you did.

Seven common trust accounting mistakes
  1. Commingling. Depositing earned fees or firm money in trust, or client funds in operating. Both are violations.
  2. Paying fees before they are earned. Moving a retainer to operating before billing and earning it is misappropriation, even if you meant to earn it next week.
  3. Negative client balances. Paying out more for a client than you hold for them, often because a deposit had not cleared yet.
  4. Skipping the monthly reconciliation. Or doing a two-way match and calling it done.
  5. Leaving earned fees in trust. Fees that sit in trust after they are earned become commingled funds.
  6. Sitting on undisputed money. Settlement funds held past 45 days without good cause.
  7. Using general accounting software alone. QuickBooks can track trust activity, but it does not natively produce client ledgers and three-way reconciliations without careful setup.
A monthly trust accounting checklist
  • Record every trust deposit and disbursement to the right client ledger the day it happens
  • Wait for deposits to clear before disbursing against them
  • Transfer earned fees out of trust promptly, with a matching invoice
  • Run a three-way reconciliation within days of receiving the bank statement
  • Review every client ledger for negative or stale balances
  • Save the signed reconciliation report with the bank statement
  • Before license renewal, gather December 31 balances and complete CTAPP

On software: Pair your practice management tool (Clio, MyCase, or similar) with your general ledger, and make sure it produces client ledgers and three-way reconciliation reports. The tool does not make you compliant. The monthly review does.
