Dealerships: Enhanced SALT Deduction in 2026

Understanding the New $40,000 Cap

The cap on the SALT deduction was one of the most controversial provisions of the 2017 tax reform, limiting the individual deduction for state and local taxes to just $10,000. The recent legislative change quadrupled this limit to $40,000 for single and joint filers (and $20,000 for married filing separately) beginning in 2025. This change is crucial for high-income earners in high-tax states, as many dealership owners are.

For 2026, the cap increases slightly due to inflation indexing, reaching an estimated $40,400 for married couples filing jointly. This deduction, claimed on Schedule A of the Form 1040, continues to provide a valuable break by lowering the owner’s Adjusted Gross Income (AGI). The stability of this higher cap, which is currently set to last through 2029, allows for a multi-year view when designing owner compensation and distribution strategies, making the post-tax value of pass-through income more predictable.

However, it’s vital to note that this benefit is temporary and subject to income limits. The full cap is reduced (phased down at a 30% rate) for taxpayers with Modified Adjusted Gross Income (MAGI) exceeding a certain threshold (estimated at $505,000 for joint filers in 2026), eventually bottoming out at the original $10,000 cap for the highest earners (estimated at MAGI over $606,333 in 2026). This “SALT torpedo” effect means that personal income planning is more important than ever for high-earning owners to maximize the deduction.

The PTE Tax Workaround and Federal SALT Cap Interplay

The most complex planning challenge for multi-location dealers lies in navigating the interplay between the new federal SALT cap and the existing state pass-through entity tax workarounds.

In response to the original $10,000 cap, over 35 states enacted elective PTE taxes. This mechanism allows the dealership (the S-Corp or Partnership) to pay state income taxes at the entity level. Since taxes paid by a business are fully deductible as a business expense on the federal return (not subject to the individual SALT cap), this shifts the tax benefit from the capped individual Schedule A to the unrestricted business level. The owner then receives a corresponding credit on their individual state return.

Now that the federal cap is $40,000, the decision of whether or not to elect the state PTE tax is no longer automatic.

PTE Advantage Remains

In high-tax states (like California, New York, or New Jersey) where the dealership’s combined state income and property taxes easily exceed $40,000, the PTE election remains the most powerful tool. It allows the deduction of state taxes far exceeding the federal cap, sometimes offering tens of thousands of dollars more in federal savings than the new $40,000 limit. Crucially, the PTE deduction also reduces the owner’s AGI, potentially improving eligibility for other deductions or credits.

Modeling is Essential

Dealership owners, particularly those with MAGI in the federal phase-out zone ($505,000 to $606,333 for joint filers in 2026), must model both scenarios: taking the state PTE tax versus relying solely on the federal $40,400 enhanced individual SALT deduction. The optimal strategy is highly dependent on the dealership’s state tax rate, the total amount of state taxes paid, and the owner’s individual income level.

A Crucial Variable in Geographic Markets

For multi-location franchise auto dealers, the variance in state-level tax policy for auto dealers becomes a critical variable in regional management and acquisition strategy.

Footprint Strategy

A state that offers a beneficial PTE tax workaround offers a better tax environment for ownership than a high-tax state without one, even with the new federal cap.

Compliance Complexity

Multi-state dealerships must manage compliance with different PTE rules across their geographic footprint, noting that some state PTE elections are mandatory, while most are annual and elective.

The enhanced federal SALT cap provides a significant floor for tax planning through 2029. However, for dealership principals whose businesses generate substantial pass-through income, the state PTE election remains the ceiling of tax efficiency. The current tax environment demands that high-income owners treat the $40,000 SALT cap and PTE election as dual planning opportunities, not a binary choice.
