California FTB PTE Elective Tax: June 15 Deadline Arrives with New 2026 Rules That Change the Penalty for Missing It
California’s pass-through entity elective tax June 15 payment deadline is two weeks away. The FTB changed how the penalty works starting with the 2026 tax year — and if you’re a California LLC, S-corp, or partnership with partners or shareholders who rely on the PTE credit to work around the federal SALT cap, missing that payment now costs you 12.5% of the unpaid amount in lost credits, not just the right to make the election at all.
How the California PTE tax actually works
California’s pass-through entity elective tax is a workaround for the federal $10,000 SALT cap. A qualified pass-through entity — an S-corp, partnership, or LLC taxed as a partnership — can elect to pay California income tax at the entity level at a flat rate of 9.3% on qualified net income. The partners or shareholders then receive a California income tax credit equal to their pro rata share of the PTE tax paid. The credit flows to their individual California returns and offsets their personal CA income tax liability dollar-for-dollar.
The federal benefit: the entity-level PTE tax is a business deduction that runs through to federal taxable income. So the partners or shareholders effectively get a federal deduction for what would otherwise be a state income tax payment — which is exactly what the SALT cap blocks at the individual level. That federal deduction is real money. For a partner in a profitable California partnership, the PTE election often saves several thousand dollars per year in federal tax, sometimes significantly more.
The tradeoff is that making the election requires the entity to make a required June 15 prepayment. Miss it or underpay it, and there are consequences — different ones starting in 2026 than applied in prior years.
What changed for the 2026 tax year
Under the rules that applied through tax year 2025, missing the June 15 prepayment meant you couldn’t make the PTE election at all for that year. Gone. No credit for the partners.
Starting with taxable years beginning on or after January 1, 2026 — and this is the change — the FTB modified the consequence. If the entity misses the June 15 deadline or underpays the required amount, it can still make the PTE election for 2026. But the credit allowed to each qualified taxpayer is reduced by 12.5% of that taxpayer’s pro rata share of the unpaid amount due.
The mechanics: say a partnership has three equal partners and the entity owed a $90,000 June 15 prepayment but paid nothing. Each partner’s share of the unpaid amount is $30,000. Each partner’s credit is reduced by 12.5% × $30,000 = $3,750. That $3,750 reduction per partner is real money taken off the credit they’d otherwise receive.
The thing most advisors miss: The FTB cannot correct the June 15 payment after June 15, 2026. If you discover an error in the payment — either an underpayment or that no payment was made — you must fix it before June 15. After that date, the reduction is locked. No amended payment, no appeal process for the reduction itself.
The required payment amount
To make a valid PTE election and preserve the full credit amount, the entity must pay the greater of:
- $1,000, or
- 50% of the elective tax paid in the prior year
For an entity that paid $200,000 in PTE elective tax for the 2025 tax year, the required June 15 prepayment for 2026 is $100,000. The balance — whatever the full 2026 PTE tax works out to — is due with the entity’s return, extended deadline included.
Entities making this election for the first time in 2026 need to pay at least $1,000 by June 15. That gets the election open. The full year PTE tax is still due with the return.
Who should care about this
California-based partnerships and S-corps with high-income partners or shareholders
The PTE credit is most valuable when the individual partners are in the highest California income tax brackets. California’s top rate is 13.3% for income above $1 million. A professional services partnership — a law firm, medical group, consulting firm — with partners earning well above that threshold typically gets substantial value from the election. For those entities, the June 15 payment should already be scheduled and on track. But confirming the amount against 2025 actual PTE tax paid is worth doing now, not June 14.
Reedcorp clients with California pass-through income
Many of our business owner clients receive K-1s from California-operating partnerships and S-corps even though they don’t live in California. Their California-source income is still taxed by the state. If the entity they hold an interest in is electing PTE treatment, their credit is coming from that entity’s June 15 payment. Checking in with the entity’s preparer before June 15 is worth doing.
Multi-state partnerships with significant California operations
California apportions income for multistate entities. A partnership that operates in New York and California must apportion its California-source income for PTE purposes. The election covers only the California-source portion. Getting the apportionment calculation right before making the election — and before determining the June 15 payment amount — is where errors most commonly occur.
The PTE program is now extended through 2031
One piece of good news buried in the June 15 reminder: SB 132 extended the California PTE elective tax program through taxable years beginning before January 1, 2031. The original sunset was January 1, 2026. That extension was signed into law, so California pass-through entities have five more years of the SALT workaround at the state level — assuming the federal SALT cap itself doesn’t change in the meantime.
It’s worth noting: the federal SALT cap has been a moving target. The One Big Beautiful Bill Act modified the cap for tax years 2025 and 2026 to $40,000 for most filers, phasing out for higher-income households. That increase reduces (but doesn’t eliminate) the PTE benefit for some taxpayers. Whether the election still makes sense under the new federal SALT parameters depends on the taxpayer’s specific income level. Do the math before assuming the PTE election is automatically worth making.
The counterintuitive reality of the $40,000 SALT cap: Some California PTE elections that were clearly worthwhile under the $10,000 cap may now break even or marginally net negative once the higher federal SALT deduction is factored in. The analysis changed with OBBBA. Entities that have been automatically renewing their PTE elections should recalculate the benefit for 2026 before paying June 15.
How to pay by June 15
The FTB accepts PTE elective tax payments electronically through FTB Web Pay using Form FTB 3893 (Pass-Through Entity Elective Tax Payment Voucher). Mailed payments using a printed FTB 3893 voucher also work but require allowing time for delivery before June 15. Electronic payment is faster and provides confirmation.
Entities that use a payroll service or accounting software should verify that the payment went through. The FTB has had intermittent issues with credit card payments taking longer to process. If you’re paying by credit card and need confirmation before June 15, allow extra time or use a bank ACH transfer instead.
Common questions
What if our entity is new in 2026 and has no prior-year PTE payment to base 50% on? The minimum required payment is $1,000. Make that payment by June 15 to open the election. The full 2026 PTE tax is then due with the return.
Does the 12.5% credit reduction apply per partner or to the total entity shortfall? Per partner. Each partner’s credit is reduced by 12.5% of their own pro rata share of the total unpaid amount. If some partners have larger ownership stakes, their individual credit reduction is larger in dollar terms.
We made the election in prior years and don’t have a formal system for the June 15 payment — what’s the best way to fix that for next year? Build a June 1 calendar reminder to calculate the required payment and authorize the FTB Web Pay transfer to arrive by June 14. Don’t wait for the return preparer to prompt this. The June 15 deadline is the entity’s responsibility, not the preparer’s.
Can a California partnership still benefit from the PTE election now that the SALT cap is $40,000? Depends on the partner’s income. At the $40,000 cap, many middle-income partners can already deduct most or all of their California taxes at the federal level without the PTE. For partners with high California income, the PTE election likely still saves money. For those in moderate brackets, run the numbers.
