Discovering that California collected too much tax is frustrating enough. Discovering the error years later, after the normal refund deadline has expired, can make the situation appear unrecoverable. A new Franchise Tax Board ruling provides an important exception in a narrow set of cases.
On August 21, 2026, the FTB issued Legal Ruling 2026-02, clarifying when money taken through an involuntary collection action is an “overcollection” rather than an ordinary tax overpayment.
If the FTB collected more than it was legally entitled to collect because of its own mechanical or clerical error, the amount may be returned even after the normal statute of limitations for a refund claim has expired.
For taxpayers reviewing old liens, levies, withholding orders, offsets, or payment histories, the way the money was collected can therefore determine whether recovery is still possible.
An overpayment and an overcollection are not the same thing
An ordinary overpayment occurs when a taxpayer pays more than the taxpayer’s actual tax liability. California’s normal refund rules generally require a refund claim by the later of one year from the date of the overpayment or the applicable four-year period tied to the return. Once that period expires, an otherwise legitimate overpayment may no longer be refundable.
An FTB overcollection is narrower. Under Legal Ruling 2026-02, it occurs when the FTB collects an excess amount at the time of an involuntary collection action because of a mechanical or clerical error by the FTB.
The ruling says the normal refund statute does not bar the return of a true overcollection because an overcollection is not treated as an overpayment of tax.
An incorrect assessment is not automatically an overcollection
If the FTB makes an assessment based on the information available to it, the assessment becomes final, and the FTB properly collects the balance. Years later, the taxpayer provides additional information showing the underlying tax should have been lower.
Legal Ruling 2026-02 says that does not necessarily create an overcollection. The FTB gives examples involving taxpayers who failed to file returns and later established that their actual tax liabilities were lower. Because the FTB had validly assessed and collected the amounts based on the information available at the time, the resulting excess was an overpayment, not an overcollection. The expired refund statute still applied.
The practical question is not simply, “Was too much tax ultimately collected?” The review should identify why the excess amount was collected and whether the collection itself contained an FTB error.
What can qualify as an involuntary FTB collection?
FTB guidance identifies involuntary collection methods that can include:
- Earnings withholding orders
- Orders to withhold funds from banks or other third parties
- Offsets of overpayments from other tax years
- Government intercepts
- A combination of these collection methods
For example, the new ruling considers a taxpayer whose liability has already been fully satisfied through an earnings withholding order, but the employer sends additional payments before the FTB stops the withholding. The FTB treats those additional amounts as an overcollection caused by a clerical timing error.
Another example involves the FTB correctly determining an assessment but collecting tax using an incorrect number because of a clerical mistake. The excess collection can be returned despite an expired refund statute.
The ruling reaches a similar result when the FTB sends required collection notices to the wrong address and then collects the liability involuntarily. Because the taxpayer did not receive the required collection due process, the ruling treats the collected amount as an overcollection.
Voluntary payments require a different analysis
Legal Ruling 2026-02 focuses on amounts obtained through involuntary collection actions. A taxpayer who voluntarily sends too much money generally has an overpayment rather than the type of FTB overcollection addressed by the ruling. That means the normal refund claim deadlines remain central to the analysis.
For older accounts, reviewing the transaction history can help identify whether the disputed amount came from a taxpayer-initiated payment, a levy, an earnings withholding order, an offset, an intercept, or another collection mechanism. Aura’s article on using MyFTB to review account and payment information can be a useful starting point.
Taxpayers should also know that Legal Ruling 2026-02 says interest is not payable when an overcollection is returned.
What to review if you think FTB collected too much
For an old California liability, reconstruct the account rather than looking only at the current balance. Review the assessment history, payment dates, collection notices, withholding or levy records, offsets, credits, and when the liability was actually satisfied. Then identify the source of the excess amount.
A clerical posting error, continued withholding after a balance reached zero, or an unlawful collection procedure may support an overcollection analysis. A later disagreement with the underlying assessment may not.
How Aura Advisors can help with FTB overcollection
An expired refund deadline does not automatically close every California collection issue, but Legal Ruling 2026-02 applies to a specific category of involuntary collections.
Taxpayers with old California liabilities should evaluate what the FTB was legally entitled to collect, how each payment entered the account, whether the assessment itself was valid, and whether a mechanical, clerical, or collection-procedure error caused the excess.
Aura Advisors can help reconstruct FTB account activity, trace payments and credits, evaluate whether an amount is better characterized as an overpayment or an overcollection, and develop a supportable approach for requesting correction when the facts fit the ruling.
