Maximizing Federal Deductions: A Deep Dive into California's PTET for Business Owners
If you are managing a successful business in California, you are likely all too familiar with the weight of state and local taxes (SALT). For years, the federal cap on SALT deductions has felt like a direct hit to the bottom line of high-earning pass-through owners. However, there is a strategic way to navigate these waters: the Pass-Through Entity Elective Tax (PTET). This planning tool is designed specifically to help you reclaim deductions that would otherwise be lost to the federal itemized deduction limit.
At Christiansen Accounting, we frequently help our clients evaluate whether this workaround makes sense for their specific situation. While several states have adopted similar measures, this guide focuses on the mechanics here in California. We will explore how PTET works, why it remains relevant despite recent legislative changes, and the practical steps needed to implement it.
The OBBBA and the New Landscape of SALT Limits
You may have heard about the One Big Beautiful Bill Act (OBBBA), which introduced temporary relief by increasing the federal SALT deduction ceiling for the 2025 through 2029 tax years. While this increase is a welcome change for many, it is important to remember that without further legislation, the cap is scheduled to revert to the restrictive $10,000 level in 2030.
Furthermore, the OBBBA introduced a phasedown mechanism for high-income earners. The deduction is reduced by 30% of the amount by which your modified adjusted gross income (MAGI) exceeds certain thresholds. This means that for many business owners, the SALT cap still poses a significant tax planning challenge. The following table outlines the maximum SALT deduction and the high-income phasedown schedule for the coming years.
SALT DEDUCTION | |||
Year | SALT Deduction Cap | High Income Phasedown | |
- | - | MAGI Phasedown Threshold | MAGI Fully Phased Down to $10,000 |
2025 | $40,000 | $500,000 | $600,000 |
2026 | $40,400 | $505,000 | $606,333 |
2027 | $40,804 | $510,050 | $612,730 |
2028 | $41,212 | $515,150 | $619,190 |
2029 | $41,624 | $520,302 | $625,719 |
2030 and Subsequent years | $10,000 | Not Applicable | |
Even with these temporary increases, the PTET remains a highly effective strategy for several reasons:
- Full Deductibility: For those with state taxes well exceeding the $40,000 range, PTET shifts that burden from a limited personal itemized deduction to a fully deductible business expense at the entity level.
- Strategic Interaction: By reducing the profit reported on your K-1, you may lower your federal marginal tax rate, protect against phasedowns of other credits, and potentially reduce your exposure to the Net Investment Income Tax (NIIT).
- Multi-Entity Flexibility: If you hold interests in multiple businesses, the cumulative effect of PTET can be substantial, especially when navigating complex state-specific carryover rules.
How the PTET Mechanism Operates
The core concept of PTET is to move the tax liability from the individual owner to the business entity itself. Here is a breakdown of the process:
- The Election: This is an annual decision. Your S-Corp, Partnership, or LLC must "opt-in" by filing a timely original tax return. It is critical to note that this election is irrevocable for that tax year. Interestingly, not every owner in the business is required to participate; the election can be made for a specific subset of consenting owners.
- The Tax Rate: The business pays a flat tax on its qualified net income—the portion of profits belonging to the participating owners. In California, this rate is currently set at 9.3%.
- The Federal Benefit: Because the tax is paid by the business, it is treated as a business expense. This reduces the net income reported on your federal K-1, allowing you to bypass the SALT cap entirely on that specific income.
- The State Benefit: On your personal California tax return, you receive a nonrefundable credit equal to your share of the tax paid by the entity. If this credit exceeds your total state tax liability, California allows you to carry the remaining balance forward for up to 5 years.
Determining Eligibility and Moving Forward
Most common pass-through structures, including S corporations, partnerships, and LLCs taxed as such, are eligible for this election. However, the rules are nuanced. For instance, sole proprietorships and publicly traded partnerships generally cannot use this workaround. Additionally, if your entity has a complex ownership structure involving other partnerships, you must verify state-specific eligibility rules.
Because the math behind PTET involves several moving parts—including your total SALT burden, your federal marginal bracket, and the impact of the OBBBA phasedowns—it is not a decision to be made on a whim. The most effective approach is to perform side-by-side modeling: comparing the results of standard itemization against the PTET election.
Final Professional Recommendations
The PTET is one of the most powerful tools available to California business owners facing federal deduction limits. However, with the temporary OBBBA changes in effect through 2029, the "obvious" choice isn't always the right one without current-year modeling. Every business has a unique footprint, and what worked last year might need adjustment this year.

Expanding on the practical application of this strategy, the timing of your PTET payments is perhaps the most critical administrative hurdle. Unlike many tax elections that can be finalized during tax season, California’s PTET requires a proactive commitment well before the filing deadline. For taxable years starting in 2022 and beyond, entities are required to make a prepayment by June 15th of the current year. This payment must be the greater of $1,000 or 50% of the elective tax paid for the prior year. If you miss this window or underpay, the Franchise Tax Board may bar your entity from making the election for that entire year, leaving you and your fellow owners with the standard federal SALT cap limitations.
Another layer of complexity involves the interplay with the Section 199A Qualified Business Income (QBI) deduction. Because the PTET is recorded as an entity-level expense, it reduces the net ordinary income passed through to owners on their K-1. Since the federal QBI deduction is generally 20% of that net income, a lower K-1 profit means a slightly smaller deduction. In our modeling at Christiansen Accounting, we consistently find that the federal tax savings from the PTET workaround far outweigh the reduction in the QBI benefit, but this is a calculation that requires precision. We look at the total tax ecosystem, including your self-employment taxes and potential exposure to the Net Investment Income Tax, to ensure the net gain is maximized.
One of the more nuanced advantages of the PTET is its impact on the Alternative Minimum Tax (AMT). By deducting the state tax at the business level, you effectively move the expense "above the line." This reduces your Adjusted Gross Income (AGI), which is the starting point for many federal tax calculations, including the AMT. In high-tax states like California, state taxes are normally added back into the AMT calculation, but the PTET avoids this add-back because it is a business deduction rather than a personal itemized deduction. This secondary layer of tax efficiency provides an additional benefit that isn't always obvious at first glance.
For those with interests in multiple entities or operations in other states, we also have to navigate the "Other State Tax Credit" (OSTC) rules. If you are a California resident with a partnership in another state that also uses a PTET-style workaround, we must carefully coordinate these elections to ensure you receive proper credit on your home state return. Managing these overlapping state-level taxes is a cornerstone of our high-level planning for multistate business owners. Our goal is to ensure your basis schedules are meticulously maintained, as the PTET payment acts as a reduction in your ownership basis, which can have significant implications for future business sales or debt-financed distributions.
