Ask a room of solo attorneys what keeps them up at night, and somewhere near the top of the list, right alongside the statute of limitations, is the trust account. Not because most lawyers are doing anything wrong, but because the rules are unforgiving in a way the rest of your books simply aren’t. One misposted deposit can sit quietly for months and still turn into a disciplinary problem, even if no client ever loses a dollar.
The good news is that the core of trust-account compliance comes down to one repeatable habit. You reconcile an IOLTA account by making three numbers agree on the same day, every month: the bank statement balance, the trust balance in your books, and the total of every client’s individual ledger. That’s called three-way reconciliation, and it’s the standard bar examiners measure your records against. When those three numbers don’t match, something is wrong, and it only gets harder to untangle the longer it waits.
Here’s how to do it, and how to sidestep the errors that turn a bookkeeping slip into an ethics complaint.
Key takeaways
- Three-way reconciliation means matching three balances on the same day: the bank statement, your trust ledger, and the total of all individual client ledgers.
- ABA Model Rule 1.15 requires client funds to stay separate from firm funds, with complete records.
- Most states expect monthly reconciliation, so confirm your own state bar’s rules.
- Commingling and recordkeeping errors can be sanctioned even when no client loses money and no harm was intended.
- A bookkeeper can run the monthly reconciliation, but the client sub-ledger stays your responsibility as the fiduciary.
Why is trust account bookkeeping different?
An IOLTA account holds money that isn’t yours. Under the American Bar Association’s Model Rule 1.15, “Safekeeping Property,” a lawyer has to keep client funds separate from the firm’s own money and maintain complete records of them (Source: ABA Model Rules of Professional Conduct, Rule 1.15, americanbar.org). Nearly every state has adopted some version of that rule, and plenty have layered their own requirements on top, so your exact obligations come from your state bar, with Model Rule 1.15 as the floor.
The piece that catches people off guard is that this is an ethics matter first and an accounting matter second. A bar examiner isn’t reviewing your tax math. They’re looking for commingling, shortages, and missing records, and in most jurisdictions, negligent trust-account management is sanctionable even when no client lost anything and you never meant to do a thing wrong (Source: ABA Model Rules of Professional Conduct, Rule 1.15, americanbar.org). Good intentions don’t get you off the hook. A clean process does.
What is three-way reconciliation?
A normal bank reconciliation matches two things: your books and the bank. For a trust account, that’s not enough, because your books can tie perfectly to the bank while one client’s money is quietly sitting under the wrong matter.
Three-way reconciliation adds the missing piece, the sum of every individual client ledger. Three balances have to land on the same number on the same date. The first is the bank statement balance for the IOLTA account. The second is the trust balance in your general ledger, which is what your books say. The third is the total of all your individual client ledgers, one running balance per client, per matter.
That third leg is the whole point. It’s what catches a deposit posted to the wrong client, a disbursement that overdrew someone’s balance, or funds still parked in trust for a matter that closed six months ago. A two-way reconciliation is blind to every one of those.
How do you reconcile an IOLTA account step by step?
Most states expect this monthly, and even where they don’t, monthly is the sane way to do it. The rhythm is straightforward once you’ve done it a couple of times.
Begin with the bank statement and pull the closing balance for the period. Reconcile your trust ledger against it, accounting for outstanding checks and deposits in transit exactly like you would on any bank reconciliation. Then total every client’s ledger, adding up the individual running balances for all matters that held funds during the period. Now compare all three balances. Same date, same penny. If they agree, document it and move on with your day.
If they don’t agree, resist the urge to force it. Dropping in a “plug” entry to make the reconciliation balance doesn’t fix the error, it just hides it, and a hidden error is exactly what a bar audit is built to find. Track down the misposted transaction and correct it properly. Then save your proof: the reconciliation report, the bank statement, and the client ledgers. The ABA baseline for keeping these is five years after the matter closes, and several states require longer, with New York, for instance, requiring seven (Source: ABA Model Rules of Professional Conduct, Rule 1.15, americanbar.org; New York Rules of Professional Conduct, Rule 1.15, and Judiciary Law § 497).
This is the kind of monthly discipline that’s the first thing to slide when you’re heads-down on client work, and it’s exactly what a dedicated bookkeeper who understands trust accounting is there to hold.
What are the most common IOLTA compliance mistakes?
The same handful of mistakes account for the overwhelming majority of trust-account problems, and none of them require bad intent.
The most common by far is bank fees hitting the IOLTA account. A wire fee or a monthly service charge that lands in trust means firm money is now sitting in a client account, which is technically a shortage. The fix is to have your bank bill fees to your operating account instead. Close behind is depositing retainers straight into operating: unearned fees belong in trust until you’ve earned them, and putting them anywhere else is commingling. The mirror image trips people up too, leaving earned fees sitting in trust after you’ve earned them and, where required, told the client. And finally there’s the untagged deposit, a retainer dropped into “IOLTA” without being assigned to a specific client, which throws off that all-important third leg immediately even though the bank balance looks perfectly fine.
Notice that these are process failures, not character failures. That’s precisely why a repeatable monthly process beats good instincts every time.
Monthly IOLTA reconciliation checklist
Run this every month, and keep the finished checklist with your records.
- [ ] Pull the IOLTA bank statement for the period
- [ ] Reconcile the bank balance to my trust general ledger (account for outstanding items)
- [ ] Total every individual client ledger with funds in trust this period
- [ ] Confirm all three balances match, same date, to the penny
- [ ] Check that no bank fees were charged to the trust account
- [ ] Confirm no client ledger shows a negative balance
- [ ] Confirm no earned fees are still sitting in trust
- [ ] Investigate and correct any discrepancy (never plug the difference)
- [ ] Save the reconciliation report, bank statement, and ledgers per my state’s retention rule
- [ ] Confirm my state’s required frequency (most are monthly) and deadline
This reflects ABA Model Rule 1.15 as a baseline. Your state bar’s rules control, so confirm your jurisdiction’s specifics.
Can a bookkeeper manage my trust account?
A good bookkeeper reconciles your IOLTA against the bank statement every month and flags anything that doesn’t match, so a problem surfaces in days instead of at an audit. What they don’t do is certify your compliance or take over your client sub-ledger. That stays your responsibility under bar rules, because you’re the fiduciary and the buck stops with you. The point of outsourcing isn’t to hand off the ethics. It’s to make sure the monthly reconciliation actually happens, cleanly, so your billable hours stay billable. That’s the whole idea behind Bench’s bookkeeping for independent professionals.

Frequently asked questions
How often do I have to reconcile my IOLTA account? Most states require it monthly, and monthly is the safe standard everywhere. A few permit quarterly at minimum, but quarterly lets errors compound for three months before you catch them. Confirm your state bar’s specific requirement (Source: ABA Model Rules of Professional Conduct, Rule 1.15, americanbar.org).
What is three-way reconciliation? It’s matching three balances on the same date: the bank statement, your trust ledger, and the sum of all individual client ledgers. All three must be identical. That third leg is what separates trust-account reconciliation from an ordinary bank reconciliation.
Can I be disciplined if no client lost money? Yes. In most jurisdictions, commingling and recordkeeping failures are sanctionable on their own, because the breach is the mishandling and the missing records, not just an actual loss (Source: ABA Model Rules of Professional Conduct, Rule 1.15, americanbar.org). Intent isn’t required either.
Can I use QuickBooks for my trust account? You can, but general accounting software doesn’t come with trust-specific guardrails, so the discipline has to come from your process (or your bookkeeper). Many firms pair general software with a bookkeeper who runs the three-way reconciliation every month so nothing slips through.
How long do I have to keep IOLTA records? The ABA baseline is five years after the matter closes, and several states require more, with New York requiring seven, for example (Source: ABA Model Rules of Professional Conduct, Rule 1.15; New York Rules of Professional Conduct, Rule 1.15). Check your jurisdiction.
