What a California Unclaimed Property Audit Examines

The short answer

A California unclaimed property audit examines a holder's own financial records — general ledgers, aged payables, payroll files, dormancy dates, and due diligence correspondence — to find property that should have been reported under Code of Civil Procedure §1530. How long it takes depends less on the State than on how complete those records already are.

An unclaimed property audit reviews a holder's own ledgers, aging reports, payroll files and dormancy dates, not just what was previously filed.
A holder that failed to report, pay or deliver property on time owes 12 per cent annual interest unless the failure had reasonable cause.
The California Voluntary Compliance Program waives that interest for holders who complete it, and it can be joined at any time, not just after a notice arrives.
Audit length tracks record quality: centralized, consistent books move faster than records split across legacy systems or missing fiscal years.
Reporting deadlines differ by industry — life insurers file before 1 May, all other businesses before 1 November — and gaps against that calendar are often what draws attention first.

Who does an unclaimed property audit actually reach?

If your business runs payroll, holds customer deposits, issues refunds, or has ever had a check go uncashed, the subject of this page already applies to you, whether or not anyone has written to you about it. The State does not reserve this scrutiny for large financial institutions. The property categories it tracks are ordinary ones: checking accounts, cashier’s checks, savings accounts, insurance benefit payments, and proceeds due to beneficiaries. Checking accounts alone account for 399,537 indexed records worth $1,078,405,026, and cashier’s checks for 682,998 records worth $785,935,117. More than 2,187 companies file 750 or more records each, which tells you this is routine business for the State, not an exceptional event reserved for a handful of banks.

The practical question for most businesses is not whether unclaimed property law applies to them, but whether their own filing history lines up with what their books actually show.

What records does the audit examine?

An unclaimed property audit is, at root, a comparison between what a holder reported and what the holder’s own records say should have been reported. Examiners typically ask for:

General ledgers and trial balances covering the years under review
Aged accounts payable and aged credit balance reports
Payroll registers showing uncashed or returned checks
Customer account records showing the date of last contact, which sets the dormancy clock
Due diligence correspondence sent to owners before property was reported
Prior unclaimed property filings and remittance records tied to the statutory reporting calendar

That calendar matters because it is the backbone against which everything else is checked. Life insurance companies file their notice report before 1 May and remit between 1 and 15 December; all other businesses file before 1 November and remit between 1 and 15 June. An audit often begins by lining up several of these cycles side by side and asking where the gaps are.

What decides how long an audit takes?

This is the part most businesses underestimate. The State does not control the pace of its own review as much as the holder’s record-keeping does. A company with one accounting system, consistent dormancy tracking, and complete due diligence files across every year under review can move through examination relatively quickly. A company that has changed systems, merged with or acquired another entity, or kept years of records only on paper will take considerably longer, because the examiner has to reconstruct what the books do not show cleanly.

Multiple fiscal years under review, inconsistent dormancy trigger dates between account types, and missing original source documents are the three things that most reliably stretch an audit out. None of them are set by the Controller. They are set by what already exists in your files before the first request letter arrives.

What does a missed report actually cost?

A holder that fails to report, pay or deliver unclaimed property on time owes the Controller interest at 12 per cent per annum, calculated from the date it should have been reported, unless the failure was due to reasonable cause. That interest accrues regardless of whether the underlying amounts are large or small, which is why gaps that look minor on a single year’s books can become significant once several years are added together.

Can a business get ahead of an audit?

Yes. The Controller waives that 12 per cent interest for a holder that participates in and completes all requirements of the California Voluntary Compliance Program. The program runs year-round, and a holder may apply at any time, not only after receiving an audit notice. Joining it before an examiner contacts you is generally the more controlled path: you are the one assembling the records and setting the pace, rather than responding to someone else’s timeline.

What should a business do next?

Before deciding whether to wait for an audit or move first under the Voluntary Compliance Program, it helps to know what your own books would show an examiner. California Unclaimed Property Services reviews holder records against the reporting calendar and the categories the State already tracks, and helps identify gaps before they become years of accrued interest. See our business escheatment audit service for what that review covers, or check pricing before you decide how to proceed.

Questions People Ask

Does every business get audited for unclaimed property?

No. Audits are not universal, but any business that holds customer funds, runs payroll, or has had uncashed checks can be selected, regardless of size. The categories the State tracks — checking accounts, payroll, insurance benefits — are common to most businesses, which is why this applies more broadly than many assume.

What triggers an unclaimed property audit?

Common triggers include a gap between what a company reported and what its own books appear to show, missed filing deadlines under the holder reporting calendar, or inconsistent dormancy tracking across account types. The specific trigger for any one company is not something we can know in advance; the calendar and the books are what examiners compare first.

How far back can an audit look?

The review period is set by the examiner based on your company's filing history and is not limited to the current reporting cycle. There is no single fixed number of years we can state here; what matters is that multiple years of records, not just the most recent one, are typically in scope.

What happens if we underreported in past years?

Interest accrues at 12 per cent per annum from the date property should have been reported, unless the failure was due to reasonable cause. That interest compounds the longer the gap goes uncorrected, which is why most holders are better off addressing past years before an examiner raises them.

Can we fix past mistakes before an audit starts?

Yes. The California Voluntary Compliance Program waives the interest that would otherwise apply, and it can be joined at any time, not only in response to a notice. Holders who apply before contact from an examiner generally control the process more than those who wait.

What records should we have ready?

General ledgers, aged payables, payroll registers showing uncashed checks, customer records showing last-contact dates, due diligence correspondence, and prior unclaimed property filings. Keeping these organized by fiscal year, rather than scattered across systems, is the single biggest factor in how quickly a review closes.

Is a holder audit the same as an individual claiming unclaimed property?

No. A holder audit examines a business's own records to find property it should have reported to the State. An individual claim works the other direction: an owner or heir recovering property the State already holds. If that is what you are looking for, see how to claim as an individual or as an heir or executor instead.

Does hiring a firm make the audit go faster?

We cannot promise a specific timeline, since that depends on the State's own review as well as your records. What a prior review can do is identify gaps against the reporting calendar and organize the records an examiner will ask for, before the request letter arrives rather than after.

How You Are Protected

Our fee is capped at ten per cent of what is recovered by Code of Civil Procedure §1582, and nothing is owed until the State Controller has paid you. If we recover nothing, you owe nothing. Our recovery fee is never asked for up front — it comes out of money the Controller has already paid you. A booking deposit on an in-person appointment is a separate thing, and is credited back against anything you are charged.
