PTET is a perfectly legal workaround that fixes this. Instead of paying state tax personally, you have your business pay the state tax. The IRS lets businesses fully deduct state tax — there's no $10,000 cap on businesses. Your state tax bill stays the same. Your federal tax bill drops by thousands.
The catch: you need to own a business (S-Corp, partnership, or multi-member LLC), and you need to live in one of the 36+ states that have set up the mechanism. Pure W-2 employees can't use this. Pure sole proprietors (freelancers without an S-Corp election) can't use this either. Enter your numbers below to see if you qualify and how much you'd save.
✓ California has PTET available
From your S-Corp, partnership, or multi-member LLC.
How much of your $10k SALT cap is already used.
A concrete example, step by step
Meet Sarah. She owns a marketing consulting LLC in California. Her business made $200,000 in profit last year. She's married, in the 32% federal tax bracket. Here's what happens with and without PTET.
- Her business earns $200,000.
- She reports the $200,000 on her personal tax return.
- California charges 9.3% on it: $18,600 in state tax, paid from her personal account.
- On her federal return, she tries to deduct that state tax.
- But the federal cap is $10,000 — she can only deduct $10,000. The other $8,600 of state tax is wasted federally.
- Her business earns $200,000.
- Her business pays California $18,600 directly (a business expense, before profit passes to her).
- On her federal return, the $18,600 reduces her business income — fully deductible, no $10,000 cap.
- California gives her a $18,600 credit on her personal state return — so she doesn't double-pay state tax.
- She saves $18,600 × 32% = $5,952 in federal tax, every year.
The key insight: Sarah pays the same total state tax ($18,600) either way. The only thing that changes is who writes the check — her, or her business. When her business writes it, the IRS treats it as a normal business expense with no cap. When she writes it personally, the IRS limits her deduction to $10,000.
Same money out of pocket. $5,952 less in federal tax. No catch.
