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 owner is in lower brackets, taking standard deduction, or in a no-tax state for personal residence.

Trade-offs and Traps

Cash flow: the entity must pay PTET via prepayments — adds to working capital requirement.
Election binds for the year — can't undo 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.
February 28: 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.
