AB 1620 adds a new state deduction that lets taxpayers subtract homeowners’ insurance premiums paid on their primary residence when computing California taxable income. The bill ties the deduction to eligibility for the homeowner’s or veteran’s property tax exemptions and requires the Franchise Tax Board to report usage metrics to the Legislature.
The measure is narrowly targeted relief for insured homeowners facing rising premiums and shrinking insurer participation in parts of California. It creates an explicit tax‑expenditure reporting path so lawmakers can track uptake, but it also reduces state revenues and places new reporting duties on the Franchise Tax Board.
At a Glance
What It Does
Creates a subtraction from California taxable income for the amount a taxpayer paid or incurred for homeowners’ insurance on their primary residence. It instructs the Franchise Tax Board to produce annual usage data for the Legislature.
Who It Affects
Homeowners who qualify for the homeowner’s exemption or the veteran’s exemption on their primary residence, tax preparers advising California filers, and the Franchise Tax Board, which must compile and report data.
Why It Matters
This is a narrowly tailored, temporary tax expenditure—targeted relief for insured owner‑occupants at a time of rising premiums—that also establishes specific reporting and performance indicators so policymakers can measure uptake.

What This Bill Actually Does
AB 1620 inserts Section 17226 into the Revenue and Taxation Code to let taxpayers subtract from California taxable income the amount they paid or incurred during the taxable year for premiums on a homeowners’ insurance policy covering their primary residence. The bill limits eligibility to residences that qualify for the homeowner’s exemption or for the veteran’s exemption under California law, rather than using a residency test based on mailing address or day‑to‑day occupancy statements.
The deduction is expressly tied to the tax computation (a subtraction when computing taxable income), and the bill uses the phrase “paid or incurred,” which captures premiums in the relevant taxable year without prescribing a particular accounting method. AB 1620 also includes the statutory findings required by California’s tax‑expenditure transparency rules: it states the goal (helping homeowners afford homeowners’ insurance amid market exits and premium increases) and specifies a single, measurable performance indicator—the number of taxpayers who claim the deduction.To enable oversight, the bill requires the Franchise Tax Board to report to the Legislature no later than December 1, 2027 and then each December 1 thereafter, providing the number of taxpayers who received the deduction for the most recent taxable year to the extent data are available.
The bill treats the report’s disclosure provisions as an exception to Section 19542, affecting confidentiality rules that ordinarily limit taxpayer data release. Finally, AB 1620 is temporary: it includes an express repeal mechanism and takes effect immediately as a tax levy under the California Constitution.
The Five Things You Need to Know
The deduction covers premiums ‘‘paid or incurred’’ during the taxable year, which may affect accrual‑basis timing for some filers.
Eligibility is tied to statutory property‑tax exemptions (homeowner’s and veteran’s), not to the filer’s chosen California filing status or a separate residency test.
The Franchise Tax Board must deliver the first usage report to the Legislature by December 1, 2027, and then annually on that date, pursuant to Government Code reporting rules.
The bill treats the reporting requirement as an exception to the state’s taxpayer confidentiality rule in Section 19542.
AB 1620 contains no dollar cap, phase‑out, or income eligibility threshold for the deduction; it applies to the amount of premiums paid or incurred without a statutory per‑taxpayer limit.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Creates the deduction for homeowners’ insurance premiums
Subsection (a) is the operative rule: it allows a deduction for the amount a taxpayer paid or incurred as premiums on a homeowners’ insurance policy for their primary residence. Practically, this operates as a subtraction in calculating California taxable income, reducing taxable income by the premium amount. The provision does not set a cap, dollar threshold, or link to federal deduction rules; it simply establishes the state subtraction for qualifying premiums.
Defines ‘primary residence’ by property‑tax exemptions
Subsection (b) defines which homes qualify: those eligible for the homeowner’s exemption under Revenue and Taxation Code Section 218 or the veteran’s exemption described in Section 205 and Article XIII, Section 3 (subdivisions (o)–(r)) of the California Constitution. By anchoring eligibility to existing property‑tax exemptions, the bill leverages local assessment determinations and avoids creating a new residency verification mechanism, but it excludes owner‑occupied homes that do not meet those exemption criteria and all nonowner units.
Performance goals, indicators, and reporting duties
Subsection (c) fulfills California’s requirement that new tax expenditures state goals and performance indicators: the Legislature frames the objective (help with affordability because insurer participation has tightened) and sets a single indicator—the count of taxpayers claiming the deduction. The Franchise Tax Board must report annually to the Legislature (first report due December 1, 2027) under Government Code reporting procedures. The statute also instructs that those disclosure rules are an exception to Section 19542, which normally protects taxpayer confidentiality, meaning FTB will provide aggregate or otherwise‑specified counts despite usual limits.
Sunset and immediate effect as a tax levy
Subsection (d) sets an automatic repeal date by which the section expires, making the deduction temporary. The bill’s second section declares the act a tax levy, triggering immediate effect under Article IV of the California Constitution. The combination of a short statutory life and immediate effect signals a temporary, budgetary decision rather than a permanent reorientation of state tax policy.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Owner‑occupants eligible for the homeowner’s exemption: They gain a direct state tax subtraction for premiums paid on their primary residence, lowering California taxable income and reducing state tax owed.
- Veteran homeowners claiming the veteran’s exemption: These homeowners receive the same subtraction, which could be particularly valuable for veterans on fixed incomes who face rising insurance costs.
- Tax preparers and accountants serving owner‑occupants: They will have a new line‑item to evaluate and can advise clients on timing of premium payments and possible tax savings.
Who Bears the Cost
- California General Fund (state taxpayers broadly): The deduction reduces state revenue collections while the bill contains no offsetting appropriation.
- Franchise Tax Board: FTB must build processes to identify and count claims, compile annual reports under Government Code Section 9795, and manage an explicit exception to standard confidentiality rules.
- Homeowners who are not owner‑occupants or who rent: Renters and owners of second homes receive no relief, so the program is narrowly targeted rather than broad‑based.
Key Issues
The Core Tension
The central tension is between targeted, immediate relief for owner‑occupants facing rising insurance costs and the fiscal and administrative costs of that relief: the bill reduces state revenue and adds reporting and confidentiality trade‑offs in order to provide temporary, uncapped assistance that may be easier to claim for some homeowners than others.
AB 1620 is simple on its face but raises several operational and policy questions. First, tying eligibility to the homeowner’s and veteran’s property‑tax exemptions simplifies verification but excludes owner‑occupants who, for administrative or timing reasons, do not have those exemptions in place.
Second, the bill’s use of ‘‘paid or incurred’’ allows timing flexibility, which benefits accrual‑basis filers, yet the statute does not clarify whether prepayments or multi‑year policies are prorated for deduction purposes—an implementation question that will require FTB guidance.
The reporting regime is the other source of trade‑offs. The Legislature chooses a blunt performance indicator—the count of taxpayers claiming the deduction—which tells you uptake but not distributional impact (who benefits by income level, geography, or claim size) or whether the deduction actually improves affordability or insurer market participation.
The statute also creates an exception to taxpayer confidentiality for reporting purposes; that narrows privacy protections and will require FTB to decide how granular its reports can be while complying with other privacy statutes and minimizing reidentification risk. Finally, the program’s sunset and lack of a cap mean the state absorbs full revenue cost for an open‑ended per‑premium benefit, raising questions about fiscal scalability and whether the relief targets those most in need.
