When Your Company’s EIN Changed: Finding Property Under the Old Name
When a company is acquired, the State Controller's unclaimed property records stay filed under the legal name reported at the time, not the acquirer's current federal tax ID. Finding that property means searching every former corporate name and building a document trail that connects the old entity to the new one.
The short answer
When a company is acquired, the State Controller's unclaimed property records stay filed under the legal name reported at the time, not the acquirer's current federal tax ID. Finding that property means searching every former corporate name and building a document trail that connects the old entity to the new one.
- The State Controller indexes unclaimed property by the owner name supplied at the time of reporting, not by a current federal tax ID.
- A company that acquires, merges with, or absorbs another business may find property still sitting under that business's former legal name.
- Claiming as a successor entity generally requires documentation such as merger filings or purchase agreements, not just a current EIN.
- If the property was reported under California Code of Civil Procedure §1530, a recovery fee may not exceed 10 per cent of what is recovered.
- There is no deadline to claim this property, so a name change years ago does not put it out of reach now.
Why would a company we bought still have unclaimed property?
If you bought a business, merged two entities, or watched your own company get folded into a new parent, there is a reasonable chance something financial was left behind in the paperwork. An uncashed vendor rebate, a stock dividend, an insurance refund, a security deposit on a lease the old entity held: any of these can end up reported to the State Controller as unclaimed, under the name the company used before the deal closed. The money does not follow the acquisition automatically. It sits under the legal name that was on file the day the holder reported it.
This is easy to miss because nobody is looking for it under that name anymore. The acquiring company operates under a new name, a new EIN, sometimes a new state of incorporation. The old identity still exists inside the State’s unclaimed property file, but nobody inside the new organization thinks to search for it.
How does the State track which name owns the property?
The State Controller’s unclaimed property file is built from what holders report: banks, insurers, employers, and other companies that owed money to someone and lost contact. The file we index runs to 14,639,722 records, and more than 2,187 companies have each reported over 750 records into it. Every one of those records carries the owner name as the holder understood it at the time, along with whatever address was on file. None of that is keyed to a federal tax ID the way a payroll or tax system would be.
That matters for an acquirer. Your company’s current EIN is not a search term the State’s records are built around. The old corporate name is. If that name changed at a merger, a stock purchase, or a simple rebrand, the property is still sitting under the version of the name that existed when it was reported, and it will not surface under a search for the name you use today.
What proof connects the old entity to the new one?
Once property is found under a former name, the harder part is usually documenting the chain between that name and the entity that now has the right to claim it. The State wants to see that the claimant is legally the same party, or the lawful successor to it, before it pays out. In practice that means assembling records such as a certificate of merger, a purchase or asset-transfer agreement, secretary of state filings showing a name change, or IRS correspondence tied to the entity’s prior tax identification. The more directly a document shows one entity becoming another, the stronger the claim.
This is where a lot of legitimate claims stall, not because the property is not owed, but because the paper trail was never assembled. If your company went through more than one transaction, assembling that chain is part of what we do when we file a business claim, and it is worth reading what the State actually asks for before you start. See what documents the State needs and claiming for a business for the specifics.
Does the 10 per cent fee cap apply to a successor business claim?
Property that a holder reported under Code of Civil Procedure §1530 is subject to a fee cap: a recovery firm may not charge more than 10 per cent of what is recovered (CCP §1582(a)(2)(C)). That cap covers the kind of property at issue here, ordinary reported property, as distinct from estates that reach the State through county probate, where the Controller has stated there are no fee restrictions for investigators (CCP §1582(a)(1)). For a business bridging an old EIN to a new one, it is the §1530 cap that applies.
No fee can be collected before the claim is approved and the State has actually paid the recovered property (CCP §1582(a)(1)(B)). Our own fee follows that rule exactly: 10 per cent of what is recovered, nothing owed if nothing is recovered. Details are on our pricing page, and the underlying rule is covered more fully at what the law says about finder fees.
What if the acquired company no longer exists as a separate filer?
Many acquisitions dissolve the target entity entirely, folding its assets and liabilities into the acquirer. That does not erase its claim to property reported in its name before the dissolution; it generally shifts that claim to whoever has legal standing as successor. Exactly who holds that standing in a particular corporate structure, especially after several layers of merger or a bankruptcy, is a question for corporate counsel, not something we advise on. What we can do is locate the property and assemble the supporting documentation once the successor relationship is established.
If your business has gone through multiple acquisitions, name changes, or restructurings over the years, it is worth treating this as a standing exposure rather than a one-time check. A broader look across every entity name your organization has used is closer to an audit than a single search, and that is exactly what our business escheatment audit is built for.
What should we do next?
Start by searching every legal name your current entity has operated under, including names used by companies you acquired, merged with, or absorbed. Our free property search covers the full file, not just the name on your current letterhead. If something turns up under an old name, or if your corporate history is complicated enough that you are not sure where to start, our full-service recovery handles the search, the documentation, and the claim filing, and we are paid only out of what is recovered.
Questions People Ask
How do I know if my company has unclaimed property under a former name?
Search every legal name your current entity has used, including the names of companies it acquired or merged with. The State Controller's records are indexed by the owner name on file at the time of reporting, not by your current federal tax ID, so an old name search often turns up property a name-only search on your current identity will miss.
Is the EIN itself stored in the unclaimed property database?
The records we index carry the owner name and address as reported by the holder, not a federal tax ID as the primary search key. That is why finding property tied to a company's prior identity usually means searching by the old legal name rather than by any tax ID, old or new.
Can we claim property that was reported before we owned the company?
Generally yes, as the legal successor to the entity that was owed the property, but the State will want documentation showing that succession, such as a merger certificate or purchase agreement. Whether your specific corporate history establishes that standing is a question worth putting to corporate counsel if there is any ambiguity.
What fee applies if we hire someone to find and claim this for us?
Property reported under Code of Civil Procedure §1530 is capped at a 10 per cent recovery fee under CCP §1582(a)(2)(C). No fee may be collected before the State approves the claim and pays it out. Our fee follows that structure: 10 per cent of what is recovered, nothing if nothing is recovered.
Is there a deadline to claim property sitting under our old name?
No. California places no deadline on claiming unclaimed property, and it is held indefinitely until claimed. The one exception is property that has been permanently escheated to the State, which is no longer recoverable, but ordinary reported property does not expire with time or with a corporate name change.
What if the company we acquired was dissolved rather than merged?
Dissolution does not erase a claim to property reported in the dissolved company's name; it typically shifts standing to whoever is its lawful successor. Establishing exactly who that is in a complex corporate history is a legal question, best confirmed with corporate counsel before a claim is filed.
Do we need the old EIN number to search for this property?
No. The State's records are organized around the owner name reported at the time, not a tax ID. What you need is the full list of legal names your organization or anything it acquired has operated under, since each one is a separate search term.

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.
