The Law Firm Month-End Close: A Day-by-Day Checklist for Operating and Trust Accounts
By Tammy Hoang, Certified QuickBooks ProAdvisor
A law firm month-end close is the set of steps that turns a month of activity into books you can trust. Firms that skip it tend to find out at tax time: transactions that were never recorded, checks that never cleared, and reconciliations that fell behind. Firms that run it every month hand their CPA clean records long before deadlines arrive.
This guide gives you a close you can start next month: a calendar, an owner for each step, a checklist for the operating account and a separate checklist for the trust account.
Why Skipping the Law Firm Month-End Close Costs More Later?
When nobody closes the books, small errors stack up. A deposit goes unrecorded, an old check sits outstanding, a card charge is coded to the wrong account. None of it looks urgent in March. By the time the CPA asks for the year's records, the firm is rebuilding twelve months at once.
A law firm month-end close prevents that by setting a rhythm. It also changes what the firm knows. Partners see a current profit and loss, a balance sheet that ties to the bank, and a list of open questions while the details are still fresh.
Law firms have a second reason to close every month. California's Rule 1.15 requires trust account records to be reconciled monthly, so one part of the close is not optional. The other parts of the close are what make that reconciliation possible, because a clean ledger is easier to reconcile than a messy one.
Good IOLTA bookkeeping and sound legal bookkeeping services share one principle: the books are finished on a schedule, not when someone has time. California IOLTA compliance and CTAPP compliance both rest on records that are current, so the close is where compliance is actually maintained month to month.
Set the Close Calendar and Assign Owners
A close needs a deadline and an owner for each step. Many firms aim to finish within about seven days of month-end. The exact number matters less than choosing one and holding to it. A consistent date lets the CPA and the partners plan around it.
A simple split of responsibilities works for most small firms:
Office manager or staff: gather receipts, record client deposits and disbursement requests, and answer questions from the bookkeeper.
Bookkeeper: record and categorize transactions, reconcile accounts, prepare the reports and keep the open-items list.
Designated licensee or managing attorney: review and sign the trust account reconciliation, and approve any unusual items.
CPA: receive the finished close package and raise tax questions before the year ends.
Treat the calendar as a working draft. If the close takes ten days in the first month, set the target at ten and shorten it as the process improves.
For the trust side of the calendar, see our guide to monthly three-way reconciliation for California law firms.
Closing the Operating Accounts, Step by Step
The operating close follows the same order each month:
Download or collect statements for every bank and credit card account, and confirm the opening balance matches last month's closing balance.
Record every transaction that has not yet been entered: deposits, payments, card charges and transfers.
Review uncategorized items and correct anything coded to the wrong account.
Reconcile each bank and card account to its statement, with any uncleared checks listed and explained.
Review accounts receivable, unbilled time and client advances for items that need attention.
Run the profit and loss and balance sheet, and compare them with the prior month.
The comparison is where problems surface. A category that doubled, or a balance that moved without a reason, is a question to ask now, not in April.
Lenders look for exactly this rhythm. Our guide to the loan-ready law firm bookkeeping checklist shows how banks read a firm's monthly close.

Orange County firms with several staff members often find the close slips because no one owns it. Naming a person and a date, even for a three-attorney office, solves most of the delay. Irvine law firm bookkeeping clients get a close calendar built around their own billing cycle.
Closing the Trust Account: The Part That Cannot Wait
The trust account close runs alongside the operating close, but it has its own standard. Under Rule 1.15, a lawyer must keep a written ledger for each client, a written journal for each bank account, all bank statements and cancelled checks, and a monthly reconciliation of those records, retained for five years from the date of appropriate disbursement.
In practice, a client trust account reconciliation compares three numbers: the bank balance, the journal balance and the total of the client ledgers. They should agree. If they do not, find the difference before the close is signed off.
Keep the trust close separate from the operating close. Attorney trust account bookkeeping depends on never letting a firm expense pass through client funds, so review trust activity on its own: new deposits identified by client, disbursements supported by authorization, and no client ledger with a negative balance.
This is where law firm trust accounting and the ordinary month-end meet. A firm that closes both on the same calendar finds that the operating review often points to trust issues, and the reverse.
Attorney trust account bookkeeping and law firm trust accounting follow the attorney client trust account rules, and a documented client trust account reconciliation each month is the evidence that they are being followed. California law firm bookkeeping that includes the trust close gives the designated licensee something concrete to sign.
If you use IOLTA bookkeeping services, ask to see the signed monthly reconciliation as part of the close package. Law firm trust accounting is much easier to defend when the paper trail is complete and the client trust account reconciliation is dated.
Review, Report and Hand Off to Your CPA
Finish with a short close package: the reconciled bank statements, the profit and loss, the balance sheet, the trust reconciliation with its signature, and the open-items list. Send it to the partners first and to the CPA on a set schedule.
Sending the CPA a clean package each month, or each quarter, changes tax season. Questions are answered while the facts are fresh, and year-end work becomes review and filing instead of reconstruction.
If the books have fallen behind, start with cleanup before the routine. Our answers to common law firm bookkeeping questions explain how catch-up and ongoing work fit together.
The State Bar's own rule is the primary source for trust records: Rule 1.15. For California's annual trust account program, see CTAPP on calbar.ca.gov.
