California PTET: The SALT-Cap Workaround for High-Income Owners

California's Pass-Through Entity Tax election lets passthrough owners pay state tax at the entity level, sidestepping the $10K federal SALT cap. Here's how to elect and when it pays off.

Why PTET Exists

The federal SALT cap limits state and local tax deductions on Schedule A to $10,000 per year.
California's top state income tax rate is 13.3%; a high-income owner with $500K of business income owes $66K+ in California state tax. Limited to $10K SALT deduction means $56K+ of unrecoverable federal tax.
PTET elections let the passthrough entity pay California state tax directly (deductible by the entity for federal purposes), then give owners a state tax credit.
Net effect: full federal deductibility of state tax on business income, typically $5K–$50K+ in federal tax savings per owner.

Mechanics: How California PTET Works

Entity-level tax rate: 9.3% of qualified net income for partners and shareholders who elect in.
Owners who consent get a credit on their California personal return equal to the PTET paid on their behalf.
Election is annual, made on Form 3804, filed with the entity return by the original due date.
Two prepayments required: June 15 (50% of prior-year PTET or 50% of current-year estimate) and the balance with the entity return.

When It Pays Off

Owner with $200K+ of California-source passthrough income → typically $5K–$20K of federal tax savings.
Owner with $1M+ of passthrough income → typically $40K–$60K+ of federal savings.
Best when owners are in high federal brackets (32% or 37%); the federal savings scales with marginal rate.
Less valuable if the owner is in lower brackets, taking the standard deduction, or in a no-tax state for personal residence.

Trade-offs and Traps

Cash flow: the entity must pay PTET via prepayments, which adds to the working capital requirement.
Election binds for the year; you can't undo it if the math turns out wrong.
Some non-California-resident owners may face complications: their home state may not give credit for California PTET.
Doesn't help with personal state tax outside the business (W-2 wages, investment income); only business income flows through PTET.

Practical Steps

October–November: model whether PTET makes sense for the coming year. Pro-forma owner returns with and without PTET election.
June 15: make the first prepayment (50% of prior-year PTET or 50% of current-year estimate, whichever is greater).
Annual: file Form 3804 with the entity return, capture credit on Form 540 for each owner.
Document the election and owner consent: California requires written consent from each electing owner.
