Pay State Taxes with Business

If you live in a high-tax state and your SALT deduction is basically capped out, you may be paying more to the IRS than you need to. PTET is one of the cleanest “workarounds” for many S-Corp owners.

Key numbers

What PTET is

The Pass-Through Entity Tax (PTET) is an optional election that lets your business pay state income tax on its pass-through income at the entity level, rather than you paying it personally. The difference matters because of how each is treated on your federal return. State taxes paid personally fall under the SALT deduction, which starts at $40,400 and phases down to $10,000 at higher incomes. PTET fixes this by moving the payment to the business level, where it becomes a fully deductible business expense.

Who it's for

Not everyone can elect PTET. You need a pass-through entity like an S-Corp or partnership, so sole proprietors don't qualify, and eligibility, rates, and deadlines vary by state.

If you have an S-Corp, you qualify for this election. Without PTET, your California income tax far exceeds the SALT cap, leaving you with a $10,000 federal deduction on a tax bill many times that. By electing into California's PTET, a flat 9.3% tax is applied to the S-Corp's net income. Assuming $500,000 in net income (after wages and other business expenses), that generates ~$46,500 in new federal deductions. PTET elections will generally make the most sense for owners who live in high-tax states, exceed the SALT cap, and have significant pass-through income.

One important nuance: PTET payments reduce your qualified business income, which slightly lowers the QBI deduction. The net benefit of PTET is still strongly positive for most S-Corp owners in high-tax states, but the interaction means you shouldn't model PTET savings and QBI savings independently — they affect each other.
