AB702 adds Section 17133.2 to California's Revenue and Taxation Code to exclude from gross income interest a taxpayer generates on an investment if that interest is stolen, sold, or otherwise transferred without the taxpayer’s consent during the taxable year. The bill applies to taxable years beginning on or after January 1, 2026, bars a deduction for any amount excluded, and takes effect immediately as a tax levy.
The change is narrowly targeted at interest income (not principal) that the taxpayer loses control of through unauthorized transfer. Practically, the measure aims to prevent victims of theft—including cyberattacks or unauthorized broker/exchange transfers—from owing state tax on investment interest they never possessed, but it creates new proof and administrative questions for taxpayers, custodians, and the Franchise Tax Board (FTB).
At a Glance
What It Does
The bill creates a California-only exclusion from gross income for 'qualified investment interest'—interest generated in a taxable year that is subsequently stolen, sold, or otherwise transferred without the taxpayer’s consent during that same year. It specifies that no deduction is allowed for amounts excluded under this section.
Who It Affects
Individual taxpayers who earn interest on investments and then lose possession or control of that interest through unauthorized transfers—commonly victims of theft, hacks, or improper trades. It also affects the FTB, tax preparers, and financial intermediaries (brokers, exchanges, custodians) that may need to provide corroborating records.
Why It Matters
This creates a state-level fix for a problem where victims might otherwise be taxed on income they no longer control. It establishes a carve-out that will produce conformity differences between California and federal returns, require new documentation standards, and potentially reduce state tax revenue depending on uptake and enforcement.

What This Bill Actually Does
AB702 adds a single new code section that excludes certain investment interest from California gross income. The exclusion applies only to interest income that a taxpayer generates during the taxable year and then loses control of because it is stolen, sold, or otherwise transferred without the taxpayer’s consent during that same taxable year.
The statute expressly limits the relief to interest (not principal or other types of income) and confines the event window to the taxable year in which the interest was generated and transferred.
The bill defines the exclusion and then closes an obvious loophole by saying taxpayers cannot also claim a deduction for the same excluded amount. That anti-duplication rule prevents taxpayers from excluding interest and then taking a separate theft-loss deduction for the excluded amount, but it leaves open how basis adjustments, recoveries, or later restorations will be handled because the text is silent on subsequent recoveries or on timing when recoveries occur in later years.Implementation will require the Franchise Tax Board to develop administrative guidance and likely documentation standards.
The law’s operative phrases—'stolen, sold, or otherwise transferred' and 'possession or control'—import factual questions about custodial arrangements, pooled accounts, transfers by intermediaries, and sales to good-faith purchasers. AB702 does not dictate evidentiary standards, dispute procedures, or interaction with federal tax treatment, so practitioners should expect follow-up guidance from the FTB and contested claims where taxpayers assert the exclusion.
The Five Things You Need to Know
Effective date: the exclusion applies to taxable years beginning on or after January 1, 2026; the bill itself takes immediate effect as a tax levy.
Scope: the exclusion covers only interest income generated during the taxable year that is thereafter 'stolen, sold, or otherwise transferred' without the taxpayer’s consent in that same taxable year.
Recovery rule omitted: the statute does not say whether amounts recovered in later years are taxable when recovered or how to adjust previously excluded income.
Anti-duplication: the bill bars any deduction 'with respect to any amount' excluded under this section, preventing taxpayers from excluding the interest and also claiming a separate loss deduction for the same amount.
Burden and proof: the text is silent on documentation or evidentiary standards, creating an enforcement and administrative gap the Franchise Tax Board must fill.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Exclusion of qualified investment interest from gross income
Subsection (a) states the operative rule: for taxable years beginning January 1, 2026, gross income 'shall not include' any amount of qualified investment interest generated by a taxpayer. Practically, this means taxpayers can reduce California taxable income by the excluded interest amount, but only under the narrow conditions the bill later defines. Because the exclusion language directly modifies the Revenue and Taxation Code’s gross income definition, it creates a state-specific divergence from federal income definitions unless the federal code contains parallel relief.
Definition of 'qualified investment interest' and scope limits
Subsection (b) defines the term as interest generated on an investment during the taxable year that, without the taxpayer’s consent and against their will, is stolen, sold, or otherwise transferred during that taxable year so the interest is no longer under the taxpayer’s possession or control. Two practical implications flow from this phrasing: (1) the loss must occur in the same taxable year the interest was generated, and (2) the statute focuses on possession/control rather than beneficial ownership, which raises complex questions for accounts held through custodians, pooled funds, or omnibus brokerage accounts.
Prohibition on deductions tied to excluded amounts
Subsection (c) prevents taxpayers from deducting any amount they exclude under this rule. That anti-duplication clause stops double tax relief on the same economic loss, but it also narrows relief pathways: a taxpayer who excludes interest under 17133.2 cannot simultaneously claim a separate theft-loss deduction or casualty-loss treatment for that same interest. Practitioners will need to consider how this interacts with basis adjustments, casualty/theft-loss mechanics, and state-level loss provisions.
Immediate effect as a tax levy
Section 2 declares the act a tax levy under Article IV of the California Constitution and makes it take immediate effect. The constitutional designation is procedural: it enables the statute to apply without the usual wait for operative dates tied to the next fiscal period. For practitioners, this means the exclusion is available for qualifying taxable years beginning January 1, 2026, and taxpayers filing returns for those years will seek the exclusion on their California returns once guidance is issued.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Victims of theft or unauthorized transfers (including cyber-hacks): Relieves state tax liability on interest they earned but no longer possessed, reducing the immediate tax burden on individuals who suffered asset-control losses.
- Retail investors using custodial platforms or exchanges: Offers targeted relief if an exchange or custodian improperly transfers interest income, particularly in high-profile crypto hacks where tracking and restitution are uncertain.
- Tax preparers and advocates focused on victim relief: Provides a clear statutory basis to request exclusion on state returns, simplifying some claim narratives compared with arguing for casualty-loss treatment under general provisions.
- Taxpayers with small recoveries: For those whose recovered amounts are minimal or delayed, excluding lost interest up front could prevent short-term liquidity pressures from state tax bills.
Who Bears the Cost
- California General Fund/State Treasury: The exclusion reduces taxable base and will likely lower state tax receipts to the extent taxpayers qualify for and claim the exclusion.
- Franchise Tax Board (FTB): Faces increased administrative and enforcement workload to establish claim procedures, audit standards, and guidance on documentation and contested claims.
- Financial intermediaries (brokers, exchanges, custodians): May receive increased requests for account records, subpoenas, or certifications to support taxpayers’ claims; could face reputational or compliance costs as a result.
- Tax enforcement and compliance budgets: Increased potential for abusive or erroneous claims raises enforcement costs and may force reprioritization within audit and collections units.
Key Issues
The Core Tension
The central tension is between delivering immediate tax relief to victims of unauthorized transfers and the risk of creating revenue loss and enforcement complexity: generous exclusions help bona fide victims but invite difficult fact-finding, potential fraud, and state-federal mismatches that shift costs and administrative burdens to the Franchise Tax Board and financial intermediaries.
The bill resolves a practical unfairness—taxing people on income they no longer control—but it does so in narrowly drafted, administratively blunt terms. The requirement that the interest both be generated and be lost 'during the taxable year' limits relief for losses that are discovered or settled in a later year, a timing rule that will cause hard cases when thefts span calendar boundaries.
The statute’s reliance on concepts of 'possession or control' versus 'beneficial ownership' will force factual inquiry into custodial arrangements and pooled-account mechanics; for example, whether interest credited to a pooled money-market account qualifies as 'possession' for an individual investor is unresolved.
Fiscal and compliance trade-offs are also significant. Because the law creates a California-only exclusion, it can produce state-federal mismatches that complicate taxpayers’ overall liability and reporting.
The bill is silent on recovered amounts: if a taxpayer later recovers the stolen interest (through insurance, restitution, or settlement), the statute does not specify whether that recovery is taxable or how prior exclusions should be adjusted. Finally, the lack of statutory evidentiary standards invites both overclaiming and disputes; the FTB will have to issue guidance about acceptable proof, but until that guidance exists taxpayers and intermediaries will confront uncertainty and potential audit exposure.
