Since its introduction, the federal State and Local Tax (SALT) deduction cap has been very expensive to many business owners. Limited to $10,000, this greatly curtailed the deductions of state taxes by the high-income taxpayer, particularly in such states as California.

However, one potent workaround that remains potent in 2026: California Pass-Through Unit (PTE) tax election. This approach can open up significant federal tax savings- when done properly- to owners of S corporations and partnerships.

The deduction of SALT enables taxpayers to deduct state tax on income and property on a federal filing. However, the $10,000 cap means:

1. The deductible state taxes are usually lost by high earners.
2. People in California, where the state tax rates are higher, are affected more.
3. The old ways of itemizing are no longer as advantageous.
4. The PTE tax comes in at this point.

The California PTE tax is a voluntary election that enables some pass-through businesses to pay entity-level state income tax as opposed to individual-level.

Key idea:

1. The state tax on qualified income to the business is 9.3 percent.
2. This is a deductible business expense on the federal tax filings.
3. Owners are allowed to get a state tax credit to offset their personal California liability.

Since the payment of the tax is made by the entity and not by the individual, this is a way of circumventing the limitation of the SALT cap.

The IRS gives businesses the opportunity to claim the amount of state taxes paid at the entity level as a normal business expense. That means:

1. The deduction does not have the SALT cap of 10,000.
2. It decreases the taxable income of the business at the federal level.
3. The benefit to the owners is indirectly in the form of reduced pass-through income.

It is, in simple terms, a deduction, limited as to the individual, that is deductible in full as a business expense.

PTE election is particularly useful in:

1. S corporation owners
2. Partnerships and LLCs are taxed as partnerships.
3. Those with high incomes who are impacted by the SALT cap.

Not every entity or owner is eligible, though. For example:

1. Individuals who own businesses are ineligible.
2. Some partners or shareholders (such as corporations) might not be included.
3. Eligibility may be influenced by the types of income and ownership.

The PTE strategy works well; you should know how it works in practice:

• Annual Election Required

A new treatment is not automatic; you have to elect PTE treatment every year.

• Payment Deadlines Matter

The election requires a prepayment (usually by June 15) to secure the election.

• Tax Rate

The PTE tax rate is at 9.3% on qualified net income.

• Credit Mechanism

The proprietors are entitled to a California tax credit worth their portion of the PTE tax paid.

• Expiration Timeline

Currently, the PTE regime will lapse after 2025 unless it is renewed- hence the importance of 2026 planning.

Suppose that a business owner has taxable income of $500,000 in California:

Without PTE:

1. Makes individual tax payments.
2. The federal deductible is only $10,000.

With the PTE election:

1. Business pays ~$46,500 in state tax (9.3%)
2. The whole amount is deductible on a federal basis.
3. A state credit is given to the owner.

The result? Potentially tens of thousands of federal tax savings.

The PTE election may be strong–but it must be planned. The following are the tips to maximize it:

• Do the calculations each year

The advantage is based on income, tax brackets (5), and ownership structure.

• Make arrangements with your CPA

Critical factors include timing, eligibility, and compliance.

• Plan for cash flow

The entity has to pay the tax in advance and it may affect the liquidity.

• Watch ownership changes

The eligibility and benefits may be impacted by the addition or removal of partners.

• Keep in touch with the laws

The strategy may be affected by extensions or changes to the rules after 2026.

Although it is a good idea, the PTE strategy is not flawless:

1. Not every income is qualifying.
2. Multi-state businesses become more complicated.
3. Not all owners might utilize the state credit.
4. Administration may be rigorous.

It is not a set it and forget it strategy- it must be managed.

The PTE tax is indicative of a larger trend: states that are devising workarounds to federal tax restrictions. It is among the most successful methods of minimizing federal tax liability without engaging in hardcore tax planning for California business owners.

The SALT cap still might exist, but it does not necessarily shape your tax fate. The PTE election available in California is a valid, IRS-approved way of reclaiming deductions that would otherwise be forfeited.

In the case of S-corps and partnerships, it is not a question of whether the PTE strategy is important or not, but whether you are leveraging it to its full capacity.
