California SB 711: Broad federal conformity update with selective state carve-outs

Adopts many post‑2015 federal tax changes while carving out specific federal provisions, adding a new historic‑rehab credit program, and tightening partnership and reporting rules.

The Brief

SB 711 resets how California adopts the Internal Revenue Code for state income and corporation taxes by updating the baseline of federal law the state references and by selectively choosing which federal changes to accept, reject, or modify. The measure wraps hundreds of technical conformity edits, targeted decouplings (for example on qualified business income, interest limits, and certain TCJA provisions), new state provisions (including a historic rehabilitation tax credit program with an annual allocation process), and administrative changes to how the Franchise Tax Board (FTB) handles audits and elections.

The practical effect is twofold: it both reduces some state–federal mismatches by bringing many federal changes into California law, and it preserves state policy choices by excluding or altering federal rules the Legislature did not wish to adopt. That mix creates immediate compliance and administrative implications for pass‑through entities, corporations, tax practitioners, nonprofit and historic‑preservation projects, and the FTB itself.

At a Glance

What It Does

Establishes a new conformity regime that makes a large set of federal income tax rules applicable to California with specified exceptions and state modifications; creates new state tax programs and technical rules; and amends filing, reporting, and audit procedures. It pairs adoption of many federal provisions with explicit carve‑outs where the Legislature preserves prior state treatment.

Who It Affects

Pass‑through entities and their owners, C corporations (including banks and financial institutions), research and biopharma taxpayers, developers pursuing historic rehabilitation projects, tax preparers and check‑cash businesses subject to expanded information reporting, and the Franchise Tax Board as administrator.

Why It Matters

The bill is a comprehensive rewrite of conformity choices—not a simple date bump—and therefore changes the state tax treatment of key items (R&D credits, net operating loss rules, retirement contributions, alimony, PPP forgiveness, business interest limits, partnership audit handling, and more). It reduces some mismatches with federal returns but creates many state‑specific rules that practitioners must model and that the FTB must implement quickly.

What This Bill Actually Does

SB 711 restructures California’s federal conformity approach by specifying a new body of federal rules California will look to while carving out specific federal provisions the state does not accept. Rather than adopting every federal change wholesale, the measure uses a selective approach: it makes many post‑2015 federal provisions applicable, but explicitly rejects or modifies rules that would conflict with California policy or revenue objectives.

The text contains dozens of granular instructions—some reinstating older state treatments, some preserving California‑specific limits, and some creating wholly state programs.

The bill adds new state tax provisions and programs. Notably, it establishes a state historic rehabilitation tax credit with an allocation process administered jointly by the Office of Historic Preservation and the California Tax Credit Allocation Committee, places annual caps and set‑asides on allocations, and imposes cost‑certification and recapture mechanisms.

SB 711 also standardizes several retirement and deferred‑compensation conformity points but limits elective deferral amounts to earlier federal indexing levels for certain taxable years and requires reporting and a later Legislative Analyst review of outcomes.On business taxation, SB 711 creates multiple, targeted decouplings: it preserves California’s pre‑federal treatment of the alternative minimum tax and modifies corporate AMT computation; it declines to apply certain TCJA provisions (for example, some changes to net operating loss and built‑in gain rules are preserved or altered); it excludes Section 199A qualified business income for state purposes; and it declines to adopt federal limits on business interest and certain depreciation and expensing expansions in many instances. The bill also overhauls the state’s treatment of partnership‑level federal audit adjustments: it establishes reporting deadlines, gives the FTB authority to require partnerships to pay at the partnership level in defined circumstances, and creates a state partnership representative construct tied to the federal partnership representative.Implementation is frontloaded and administratively-focused.

The measure supplies detail on when taxpayers can claim credits or carryovers, the mechanics of cost certifications, how carryforwards and basis adjustments interact with disallowed federal items, and procedural rules for amended returns and notices. It also includes multiple waivers of the Administrative Procedure Act for FTB rulemaking in specific areas, and it contains several temporary provisions and sunsets (for example, a temporary state rule on alimony tied to older federal law that expires on a statutory sunset date), all of which create planning windows of limited duration that taxpayers and advisers must track.

The Five Things You Need to Know

1

R&D credit changes: the bill preserves state R&D credits but forces a long transitional regime—pre‑2025 taxpayers can rely on a state‑modified alternative incremental credit with tiny effective rates (about 1.49%, 1.98%, 2.48%), while for taxable years beginning January 1, 2025, the state adopts a modified alternative simplified credit with effective rates changed to 3% and 1.3% in the statutory language.

2

Historic rehabilitation credit program: creates a state historic‑rehab credit with an annual aggregate allocation cap of $50 million (2021–2027), set‑asides for small projects, cost‑certification requirements (CPA for >$250k), and an allocation forfeiture if rehabilitation does not commence in the Office’s regulatory time frame.

3

Alimony/maintenance: for state tax purposes California keeps pre‑2015 alimony treatment but bars application of those rules to instruments executed after December 31, 2025 (and contains a statutory sunset of the state rule on December 1, 2027), creating a two‑year transition window.

4

Partnership audit and adjustment regime: audited partnerships must report federal partnership‑level adjustments to the FTB within six months of a final federal determination; the statute imposes a partnership‑level tax calculation option, strict reporting deadlines, and binds the state partnership representative to the federal partnership representative unless a different designee is chosen.

5

Selective decoupling on business provisions: the bill expressly disapplies Section 199A (QBI), the federal business interest limitation (Section 163(j)) in specified ways, and multiple TCJA expensing and depreciation expansions, so many federal deductions and limits will produce different state results.

Section-by-Section Breakdown

Section 1 (17024.5)

New baseline and rules for applying federal law to California

This section recasts how California defines the ‘‘Internal Revenue Code’’ for state law: it establishes a concrete baseline of federal law the Legislature will treat as incorporated and specifies the translation rules for applying federal provisions to state law (substituting terms, adjusting dates, and clarifying when federal regulations apply). Practically, it is the plumbing that lets dozens of later provisions in the bill pick and choose which pieces of federal tax law to accept, modify, or reject. For practitioners the key takeaway is the statutory framework for state‑specific exceptions—many later sections refer back to this conversion and substitution logic when they say a federal provision “shall apply, except as otherwise provided.”

Section 3 / 23609 (R&D credits)

State R&D credit retained but sharply modified and localized

SB 711 keeps a state research credit but imposes multiple California‑specific restrictions: qualified research must generally be performed in California; the statute adjusts the alternative incremental and alternative simplified credit rate structure and phases in different effective percentages for different taxable‑year cohorts; certain passthrough, consortium, and small‑business subrules from the federal statute are explicitly excluded; and gross receipts tests and carryover mechanics are recalibrated to reflect in‑state sales. The net effect is a continued state incentive for R&D, but with substantially different effective rates, in‑state nexus rules, and administrative constraints that will change project economics and tax modeling.

Section 4 / 84 (17053.91 / 23691 Historic rehabilitation credit)

Creates a state historic rehabilitation tax credit with allocation, caps, and recapture

SB 711 establishes a new refundable‑style (credit against tax) historic rehabilitation tax credit administered via allocations from the California Tax Credit Allocation Committee and the Office of Historic Preservation. The statute prescribes application, cost‑certification, Secretary of the Interior standards, set‑asides for small and affordable projects, a $50 million annual aggregate allocation cap through 2027, and recapture rules if the rehabilitated property fails to meet occupancy or use requirements. Importantly, the statute also contains an awkward funding caveat: absent appropriations language the bill limits the effective credit amount during certain years to zero, creating a compliance puzzle—allocations, certifications, and administrative obligations are in place even while the credit’s ability to reduce taxes depends on separate budget action.

Section 27 / 97 / 17201.1 (Research amortization and fringe rules)

Selective treatment of research deduction/amortization and fringe benefit limits

The bill preserves an earlier state position on Section 174 (research costs) by adopting the Code as it read on an earlier baseline for certain amortization rules, and it declines to adopt several federal changes to fringe benefit deduction limits (Section 274 and related TCJA amendments). That choice keeps many smaller taxpayer R&D expensing rules and employer deduction limits in their pre‑federal‑change form under California law, which affects capital budgeting and the timing of deductions for both employers and research labs.

Section 15 / 28 / 17201.3 / 17091 (Alimony and divorce instruments)

Temporary preservation of pre‑2015 alimony rules, with a transition window and sunset

SB 711 keeps the pre‑2015 federal alimony rules in state law for now, but it draws a bright line: the retained treatment does not apply to divorce or separation instruments executed after December 31, 2025, and the statutory scheme sunsets December 1, 2027. The provision therefore creates a temporary planning window during which existing federal‑style alimony treatment continues for state returns, while taxpayers and courts must account for the new federal treatment in post‑2025 instruments.

Section 43 / 17276 / 24416 (Net operating losses and carryover rules)

Complex, state‑specific NOL rules and transitional carryover schedules

SB 711 retains and recalibrates California’s net operating loss regime rather than mirroring all federal post‑TCJA changes. It prescribes different carryforward percentages and carryback rules across taxable‑year cohorts, special rules for ‘new businesses’ and eligible small businesses, and unique interaction rules with combined reports and water’s‑edge elections. Compliance requires historical loss accounting because carryover windows, absorption order and carryforward periods vary depending on when the NOL arose and the kind of business that generated it.

Section 64 (18622.5 Partnership audit adjustments)

Partnership audit reporting, optional partnership‑level payment, and state partnership representative

This provision implements a California framework to handle federal partnership‑level audits: partnerships receiving federal adjustments must report them to the FTB within prescribed timelines (typically six months), and the FTB can require partnership‑level payment in lieu of partner‑level adjustments. The statute aligns the state with federal partnership audit mechanics while preserving California options (including permitting partnerships to request an alternate election). It also designates the federal partnership representative as the initial state representative unless the partnership designates a different qualified person—meaning the federal representative’s actions can bind partners for state purposes unless formally changed.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Owners and developers of certified historic structures: the bill creates a state rehabilitation credit allocation process, set‑asides for smaller projects and affordable housing, and cost‑certification rules—projects that secure allocations get a structured, long‑term tax incentive (subject to appropriations).
  • Research and biotech companies conducting in‑state R&D: the state preserves an R&D credit targeted to California activities and specifies provisions to include biopharma and certain biotech actors in eligible research consortium rules, preserving a state incentive (though at modified effective rates).
  • Small employers and savers using deferred‑compensation and retirement plans: the bill preserves certain earlier federal indexing thresholds and postpones some federal changes to elective deferral limits, preserving more generous state pretax treatment for earmarked years and simplifying basis recovery for excess deferrals.
  • Taxpayers with forgiven PPP and CARES Act EIDL advances: multiple sections confirm that covered loan forgiveness and certain emergency grant advances are excluded from California gross income, aligning state treatment with federal exclusion for those covered years.
  • Partnerships that can elect partnership‑level payment or timely report federal adjustments: the statute provides a structured state process (including an elected partnership payment option and an alternate election process) that allows partnership taxpayers to limit partner compliance burdens if they can satisfy FTB requirements.

Who Bears the Cost

  • Pass‑through owners who relied on 199A: the bill disapplies Section 199A for state purposes, so owners who planned using state QBI passthrough deductions will face higher state taxable income and need to recompute state obligations.
  • Corporations and financial entities subject to modified AMT and decoupled TCJA provisions: firms lose certain federal expensing and business‑interest advantages at the state level and must maintain separate state basis and AMT computations, increasing compliance costs.
  • Tax preparers, check‑cashers, and businesses subject to expanded information reporting: SB 711 tightens reporting deadlines, raises criminal penalties for willful failures, and expands which transactions require informational returns, increasing administrative burdens and potential liability exposure.
  • Franchise Tax Board (and state budget): the FTB must implement many technical rules, adjudicate allocation and recapture for the new historic credit, handle partnership reporting and elections, and issue guidance—some of which the bill exempts from the Administrative Procedure Act—imposing operational and potentially unfunded costs.
  • Taxpayers facing transitional uncertainty (divorce parties, businesses with NOLs): temporary sunsets, cohort‑specific NOL rules, and phased changes create planning risk and recordkeeping burdens for taxpayers trying to optimize timing given shifting state rules.

Key Issues

The Core Tension

SB 711’s central dilemma is the trade‑off between simplification and control: updating conformity to capture many federal changes reduces mismatches and administrative reconciliation burdens, but the Legislature simultaneously preserves state policy through many selective carve‑outs and temporary windows—an outcome that reduces revenue and policy risk for the state while increasing complexity and compliance costs for taxpayers and the Franchise Tax Board.

SB 711 takes a hybrid approach: it imports many federal changes into California law while carving out a long list of federal provisions the state rejects or modifies. That approach reduces some federal‑state mismatches but increases the number of state‑specific rules practitioners must track.

Implementation will require careful mapping of federal positions to dozens of state exceptions—especially for items such as R&D credits, NOL carryovers, partnership audit adjustments, and depreciation/expensing rules. Practically, that means tax software, compliance processes, and FTB guidance must handle parallel federal and state treatments for the same taxpayer in many cases.

Several implementation tensions are immediate. First, the new historic rehabilitation allocation program is operationally complex: it creates application, certification, and recapture obligations but also contains a proviso that the credit amount for certain years is zero absent separate appropriations—raising the unresolved question of how allocations, applicant costs, and taxpayer reliance interact with budget timing.

Second, the partnership audit provisions bind the state to federal representative actions unless a separate state designation is made; that alignment eases collection in many scenarios but also raises due‑process and coordination questions where federal and state elections diverge. Third, the bill includes multiple waivers of the Administrative Procedure Act for FTB rulemaking in specified areas, accelerating implementation but reducing formal public rulemaking and opening the door to administrative discretion and later litigation over guidance that otherwise would be subject to notice‑and‑comment.
