The Two-Sided Business Audit for Unclaimed Property

• A business can simultaneously be owed unclaimed property as a former payee and owe unclaimed property as a holder of stale accounts.
• California's unclaimed property file holds 14,639,722 individual records, searchable by exact business name as well as by individual name.
• A holder that fails to report escheatable property on time owes the Controller 12 per cent annual interest from the date it should have been reported, absent reasonable cause.
• The State places no deadline on claiming money owed to a business; the real deadline risk runs the other way, on what the business owes.
• The California Voluntary Compliance Program waives that interest for holders who complete its requirements, and it can be joined at any time of year.

Why would my business show up on both sides of this?

Most finance teams think of unclaimed property as a personal matter: an old bank account, a forgotten paycheck, a relative’s estate. A business entity is treated no differently by the State’s system. If a vendor refund was mailed to your company’s old address and returned, if a dividend check for shares your business held was never cashed, or if an insurance proceed was issued to a corporate name that later merged or changed, that property escheats to the Controller exactly as a personal check would. At the same time, the same business may be the one that generated an uncashed payroll check, a customer credit balance never refunded, or a voided rebate that was never followed up. One exercise, run properly, turns up both.

What property might California already be holding for my business?

The State’s index currently holds 14,639,722 property records, reported by businesses large and small; 2,187 companies alone have filed 750 or more records each. The categories that dominate by value are instructive: Checking Accounts ($1,078,405,026 across 399,537 records), Cashier’s Checks ($785,935,117 across 682,998 records), Underlying Shares/Outstanding Certificates ($953,469,494 across 327,497 records) and Proceeds Due Beneficiaries ($942,278,119 across 233,788 records). These are exactly the categories a business is likely to appear in: a returned dividend, an old operating account, an insurance payout that never reached the right office. A business should be searched under its current legal name, any prior name, and any entity it has since merged into or acquired, since property reported years ago may still carry the earlier name.

Start with a free search across the full record index rather than assuming the business has nothing on file.

What property might my business owe the State?

Holders of property are required to report it to the Controller once it meets the dormancy and reporting conditions set out in Code of Civil Procedure §1530. In practice this covers the same categories that appear on the owed side: stale payroll checks, uncashed vendor refunds, unreturned customer deposits, unclaimed rebate or credit balances, and voided checks that were never reissued. A business that has never run this check may be sitting on property it is legally required to report and has not.

What is the reporting calendar, and what happens if we miss it?

Life insurance companies file their notice report before 1 May and remit between 1 and 15 December. Every other type of business files its notice report before 1 November and remits between 1 and 15 June. Extension requests must be filed no later than 30 days before the report is due. (State Controller, Report Unclaimed Property)

A holder that fails to report, pay or deliver on time owes the Controller interest at 12 per cent per annum, calculated from the date the property should have been reported, unless the failure was due to reasonable cause. The Controller is required to waive that interest for a holder that participates in and completes the California Voluntary Compliance Program, which runs year-round and can be joined at any time, not only after a problem surfaces. (Code of Civil Procedure §1577)

How does a two-sided audit actually work, and what does it cost?

A proper audit runs in two directions at once. On the owed side, it means searching the current legal name, prior names, and any merged or acquired entities against the full record index, and checking whether the business or its officers appear as named beneficiaries or heirs in the Controller’s separate probate estates file. On the owing side, it means pulling the general ledger for stale checks, unreturned deposits and unresolved credit balances that may already be reportable, before the State or a holder audit finds them first.

Where recovering property on your behalf is concerned, we charge a percentage of what is actually recovered and nothing if nothing is recovered, consistent with the statutory cap on recovery fees. That 10 per cent cap applies to property reported under §1530; it does not reach estates that pass through county probate, which fall under the Probate Code and carry no fee restriction for investigators. No fee is ever collected from you before the Controller has approved the claim and paid it. (Code of Civil Procedure §1582)

What should we do next?

Search the business name, its predecessors, and any related entities before assuming there is nothing to find. If the search turns up property, our business claim process explains what the Controller requires to pay a company rather than an individual. If you want the full two-sided review, including a look at what your own books may owe, our business escheatment audit covers both directions in one engagement. Either way, this is not a matter where delay costs you the property itself, since California holds it indefinitely; the cost of delay runs the other way, in interest accruing on what the business has not yet reported.
