An act to add and repeal Sections 17053.90 and 23623 of the Revenue and Taxation Code, relating to taxation, to take effect immediately, tax levy.
SB 587 would create a temporary personal income tax and corporation tax credit for taxpayers that paid sales tax reimbursement or use tax on tangible personal property that otherwise would have qualified for California’s partial manufacturing/research-and-development sales and use tax exemption, but for the fact that local sales taxes, transactions and use taxes, and certain local-funding sales tax rates still apply. The credit would be available for taxable years beginning on or after January 1, 2026, and before January 1, 2031, and would generally equal the amount of those qualifying tax payments. The bill applies to both individual and corporate taxpayers through new Revenue and Taxation Code sections 17053.90 and 23623.
The measure also sets out administration and oversight rules. It allows unused credits to be carried forward for up to eight years, limits claims to timely filed original returns, and requires amended returns in certain cases if the property is moved out of state within one year. It authorizes information sharing between the California Department of Tax and Fee Administration and the Franchise Tax Board for administration, and it directs the Department of Finance to provide annual revenue-loss estimates to the Legislature. The credit would only be available for years in which the Legislature appropriates money in the Budget Act for administration, and the bill includes the Section 41 tax-expenditure findings, goals, performance indicators, and reporting requirements.
In terms of state law, SB 587 would add a new tax expenditure to the Personal Income Tax Law and the Corporation Tax Law and would temporarily modify how certain sales and use tax burdens are offset for qualifying manufacturing-related purchases. It would not change the underlying sales and use tax exemption itself; instead, it would create an income/corporate tax credit to reimburse taxpayers for the local and other tax components that remain payable under existing law. The bill is also structured as an immediate tax levy and would be repealed after its operative period, with reporting provisions extending beyond that period.
The general sentiment reflected in the voting history is strongly favorable. The bill advanced unanimously through the committees and on Senate floor action reflected in the record, with no recorded opposition in the provided votes. Its movement through committee, including referral to Appropriations and placement on suspense file before later approval, suggests it was treated as a fiscal measure but not a controversial one in the available record.
The main point of potential contention is fiscal cost and administrative complexity. Because the credit would reduce General Fund revenue, the bill requires annual revenue-loss estimates and makes the credit contingent on Budget Act appropriations for administration. Another possible issue is the need for interagency data sharing and anti-fraud rules, since the Franchise Tax Board would rely on tax agency information to verify claims. The policy rationale stated in the bill is to encourage new and continued investment in California manufacturing and research and development, so debate would likely center on whether the credit effectively supports that goal and whether the revenue loss is justified.
SB 587 would add temporary tax credits to the Personal Income Tax Law and Corporation Tax Law for qualifying sales and use tax payments tied to purchases that would otherwise fall under California’s partial manufacturing/research-and-development sales and use tax exemption. The bill would not alter the underlying sales and use tax exemption itself, but would create a new offset at the income and corporate tax level for the local and other tax components that remain payable. It would also authorize data sharing between CDTFA and FTB, require annual fiscal reporting, impose claim and carryover limits, and sunset the credit after the 2026–2030 taxable-year window, with repeal provisions later taking effect.
The available voting record shows broad support and no recorded opposition: the bill passed committee votes unanimously and advanced on the Senate floor without a recorded nay in the provided history. The absence of committee transcript material limits insight into debate, but the procedural path suggests the measure was generally viewed favorably as a manufacturing and investment incentive, while still being handled as a fiscal bill requiring Appropriations review.
The likely areas of contention are the revenue cost to the state, the administrative burden of verifying qualifying purchases, and whether the credit duplicates or complements existing sales and use tax exemptions. The bill’s requirement that the Legislature appropriate money each year for administration, plus annual revenue-loss estimates from the Department of Finance, indicates concern about fiscal exposure. Any debate would also likely focus on whether the credit meaningfully advances manufacturing and R&D investment, as the bill’s stated policy goal, and whether the local tax reimbursement structure is the most efficient way to deliver that incentive.
