Navigating the SALT Cap: How PTET Benefits Long Island Business Owners
If you manage a business in Medford, Brentwood, or Mastic, you likely understand the frustration of the federal cap on state and local tax (SALT) deductions. For high-earning pass-through owners, this limit has historically meant leaving significant money on the table. However, the pass-through entity elective tax (PTET) has emerged as a critical planning tool, allowing eligible business owners to reclaim these deductions by shifting the tax burden from the individual to the entity level.
By electing to pay state taxes through a partnership or S corporation, owners can effectively convert what would have been a limited itemized deduction into a fully deductible business expense. This article explores the mechanics of the PTET workaround, utilizing California’s 9.3% rate as a baseline example, while acknowledging how these rules apply to the evolving federal landscape.
The Impact of the One Big Beautiful Bill Act (OBBBA)
The legislative environment changed with the introduction of the One Big Beautiful Bill Act (OBBBA), which temporarily adjusted the SALT deduction limits. While the 2025 OBBBA legislation provided a higher ceiling for federal SALT deductions from 2025 through 2029, the PTET strategy remains a cornerstone for sophisticated tax planning. Without further intervention, these increased limits are set to revert to the standard $10,000 cap in 2030.
Furthermore, the OBBBA introduced a phasedown for high-income earners. For those whose modified adjusted gross income (MAGI) exceeds specific thresholds, the SALT deduction is reduced by 30% of the excess, though it will not fall below the $10,000 floor. The table below outlines these adjustments for the upcoming tax years.
| SALT DEDUCTION AND PHASEDOWN SCHEDULE | |||
|---|---|---|---|
| Year | SALT Deduction Cap | 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+ | $10,000 | Not Applicable | Not Applicable |
Despite these higher temporary caps, PTET continues to be a superior option for many taxpayers on Long Island for several reasons:
- Full Federal Reduction: Taxpayers with state tax liabilities exceeding $40,000 can still use PTET to transform the entire state tax amount into an entity deduction, bypassing the federal cap entirely.
- Favorable Interactions: Even if your SALT total is below the temporary ceiling, the entity-level deduction can lower your pass-through income. This helps prevent taxpayers from being pushed into higher marginal brackets or triggering the Net Investment Income Tax (NIIT).
- Multi-Entity Advantages: For those owning multiple businesses, PTET offers a way to manage state tax credits and carryover rules more efficiently across their entire portfolio.
The Mechanics of the PTET Strategy
To successfully implement this workaround, owners must follow a specific process that begins at the business level. Here is the basic conceptual framework:
- The Annual Election: The business—whether it is an S-Corp, Partnership, or LLC taxed as such—must formally opt-in to the PTET. This election is made on a timely filed original return and is irrevocable for that specific tax year. Notably, participation is flexible; not every partner or shareholder is required to opt-in for others to benefit.
- The Tax Calculation: The entity pays tax on the "qualified net income" attributable to the participating owners. For instance, in California, this is calculated at a flat 9.3% rate.
- The Federal Deduction: Since the business pays the tax, it is recorded as a business expense. This reduces the profit reported on the participating owner’s federal K-1, essentially allowing for a full federal deduction of state taxes.
- The State Credit: On their personal state tax returns, participating owners receive a nonrefundable credit equal to the tax paid by the entity on their behalf. In many states, including California, any excess credit can be carried forward for up to five years.
Determining Eligibility and Moving Forward
Eligible entities generally include most pass-through structures such as S corporations and partnerships. However, the strategy is typically unavailable for sole proprietorships or publicly traded partnerships. Ownership complexity, such as tiered partnerships, requires careful review of specific state regulations to ensure compliance.
Because the math behind PTET has been altered by the 2025 OBBBA legislation, a "one-size-fits-all" approach no longer applies. Effective tax planning for your Medford or Mastic business now requires modeling both scenarios: traditional itemized deductions under the current SALT cap versus the PTET election.

When analyzing the financial feasibility of this election, it is important to look closely at what constitutes 'qualified net income.' While our example used a flat rate, the underlying calculation typically includes the sum of the distributive shares of income for all electing partners or shareholders. For a business owner in Medford or Brentwood, this means assessing whether the income is sourced within the state or globally, depending on the residency status of the owners. In New York, for example, the PTET calculation can vary significantly based on whether a partner is a resident or a non-resident, which adds a layer of complexity to the initial modeling phase.
Another often-overlooked advantage of the PTET is its impact on the Net Investment Income Tax (NIIT). By reducing the overall federal adjusted gross income through an entity-level deduction, business owners may find themselves below the thresholds that trigger the 3.8% surtax on investment income. This creates a secondary tax-saving effect that isn't immediately obvious when just looking at the SALT cap itself. For family-owned businesses or those with significant passive income, the reduction in federal tax exposure can be substantial, making the PTET a multi-layered defense against high tax brackets.
Timing is also a critical factor in this strategy. For a cash-basis entity to secure a federal deduction for the current tax year, the PTET payment must generally be made before the year-end. This requires proactive cash flow management during the fourth quarter. We often see business owners in Mastic or Brentwood coordinate these payments in December to ensure their federal K-1 reflects the deduction. If the entity is on an accrual basis, the rules differ slightly, but the goal remains the same: ensuring the federal benefit is captured in the same window as the state-level expense.
Furthermore, the interaction between states can be tricky for those who live in New York but have business interests in other states like New Jersey or Connecticut. Most states now offer a 'resident credit' for taxes paid to other jurisdictions, but not all states treat the PTET credit the same way. It is vital to confirm that your home state will recognize the entity-level tax paid elsewhere as a credit against your personal income tax. Without this reciprocity, you could inadvertently face double taxation on the same dollar of profit, which would negate the federal benefits of the SALT workaround.
Finally, consider the long-term carryforward implications. If a business has a particularly high-income year followed by a leaner one, the nonrefundable credit generated by the PTET might exceed the owner's personal tax liability. While the ability to carry this credit forward for five years provides a safety net, it does impact the immediate liquidity of the business. Planning for these peaks and valleys in profitability ensures that the 'benefit' of the PTET is actually felt in your bank account and not just on a tax form. We encourage all our clients to review their five-year business projections before committing to an irrevocable election for the current cycle. Making the right move now can protect your hard-earned revenue for years to come.
