California PTE Elective Tax: Extended Through 2030, and the June 15 Deadline Is No Longer Fatal

California's pass-through entity elective tax, usually called the PTE or PTET, lets S corporations and partnerships pay California income tax at the entity level so owners can deduct it federally without running into the state and local tax deduction cap. Two things changed recently that matter to every California business owner using it: the election was extended through 2030, and the June 15 deadline is no longer fatal.

What SB 132 changed

On June 27, 2025, Governor Newsom signed Senate Bill 132 as part of the 2025-26 budget package. It extends the PTE elective tax and credit for taxable years beginning on or after January 1, 2026, and before January 1, 2031. The original program was set to expire after 2025.

SB 132 also made a change that removes the single most dangerous trap in the old rules. For 2022 through 2025, missing the June 15 prepayment meant the entity could not make the election at all for that year. There was no cure. Starting with the 2026 tax year, under R&TC section 19914(b), an entity that misses or underpays the June 15 payment can still make a valid election. Instead of losing the election, each owner's credit is reduced by 12.5% of that owner's pro rata share of the amount that was due but unpaid.

The problem the PTE solves

The 2017 Tax Cuts and Jobs Act capped the federal deduction for state and local taxes. An owner paying tens of thousands in California income tax could deduct only a fraction of it federally. California, along with more than 30 other states, responded with an elective entity-level tax. The entity pays the state tax, deducts it as a business expense on the federal return where no cap applies, and the owner receives a California credit for the same amount.

How it works

The entity elects, on a timely filed original return, to pay 9.3% of each consenting owner's share of California qualified net income.
That payment is deducted on the entity's federal return, reducing income that flows through to each owner. California requires the deduction to be added back in computing the entity's California net income.
Each consenting owner claims a California credit equal to 9.3% of their share of qualified net income.

The owner's California tax bill is roughly unchanged. The federal bill goes down. That difference is the entire benefit.

A worked example of the savings

ABC Inc. is an S corporation with one owner, John, and $200,000 of California net income. Assume a 25% effective federal rate.

Without the PTE. John reports $200,000 federally and owes about $50,000. He owes California $18,600, and the SALT cap limits how much of that helps him federally.

With the PTE. ABC Inc. pays $18,600 to California and deducts it, so $181,400 flows through to John. His federal tax drops to about $45,350. He still owes California $18,600, but the credit offsets it on his personal return because the entity already paid it.

Net result: roughly $4,650 in federal tax saved on the same $200,000 of income.

The two payment dates

June 15 of the tax year. The entity must pay the greater of $1,000 or 50% of the prior year's PTE elective tax.
The original due date of the entity return, generally March 15. Extensions do not extend this date.

Payments must go through Web Pay, electronic funds withdrawal, or Form FTB 3893, and cannot be combined with the entity's other tax payments.

One planning note: to deduct the amount in the current year, the entity has to actually pay it during that year. Owners who want the deduction now often pay the balance by December 31 rather than waiting until March.

What the 12.5% credit reduction actually costs

The FTB's own example makes the math concrete.

Partnership A elected for 2025 with $500,000 of qualified net income and a $46,500 PTE elective tax. Its required 2026 June 15 payment is $23,250, half the prior year amount. It pays only $10,000.

For 2026, three partners consent, each with $100,000 of income, so qualified net income is $300,000 and the elective tax is $27,900. The election is still valid.

Each partner's credit would normally be $9,300, which is 9.3% of $100,000. The reduction is 12.5% of that partner's share of the $13,250 shortfall:

12.5% × ($23,250 - $10,000) × ($100,000 / $300,000) = $552

Each partner's credit drops from $9,300 to $8,748.

So the June 15 date is now expensive rather than fatal. Missing it entirely on a large prior-year liability can still cost real money, and it is a permanent loss rather than a timing difference. Pay it.

There are no exceptions for an unusual income year. If 2026 was a spike year, the 2027 June 15 payment is still 50% of the 2026 elective tax, whatever the business looks like in 2027.

Where the higher SALT cap fits in

The 2025 federal tax legislation raised the SALT deduction cap from $10,000 to $40,000, with a phase-down beginning above $500,000 of income. For an owner with a modest California tax bill, more of it is now deductible without the PTE, which shrinks the benefit. For higher-income owners hitting the phase-down, the PTE still does most of the work. This is now a calculation, not an automatic yes.

The parts people get wrong

The election is irrevocable and binds every owner, consenting or not. It cannot be made on an amended return, though a superseding return filed within the extension window counts as timely.
Only consenting owners are included, and their entire distributive share plus guaranteed payments goes into qualified net income. It is all or nothing per owner.
A negative K-1 means that owner is excluded from qualified net income and earns no credit.
The credit is applied after the other state tax credit and cannot reduce the 1% behavioral health services tax.
It cannot be claimed on a nonresident group return. It only appears on the individual's return, on Form 3804-CR.
Unused credit carries forward five years, and that carryover survives even in years the election is not operative.
Federal estimated taxes need adjusting. The deduction lowers flow-through income, and owners who do not update estimates overpay all year.
Nonresident 7% withholding still applies. The election does not change it.

How we handle it for clients

For clients on an advisory membership, the PTE is part of the standing planning calendar rather than something to remember. We calculate the June payment, provide the voucher, revisit the number at year-end planning to decide what to pay by December 31, and coordinate the credit onto the personal return. When multiple states are involved, we model the combination rather than treating each state separately.

If you have a California S corporation or partnership and want to know whether the election still pencils out under the higher SALT cap, that is a better conversation to have during the year than at filing time.
