To break California residency, you must establish true AZ domicile — not just spend fewer days in CA. This means your primary home, driver's license, voter registration, banking, professional memberships, and primary business activity must move to Arizona. California audits former residents aggressively, especially high earners. We guide the transition and document every element.

Arizona's TPT is a tax on the vendor (not the buyer) for the privilege of doing business in AZ — it's legally different from a typical sales tax, though it functions similarly. Retailers, contractors, restaurants, and many service businesses owe TPT. Rates vary by municipality and business category. We handle all TPT filings and ensure you're registered in the right jurisdictions.

California has two separate nexus thresholds, and which one applies depends on the tax. For sales and use tax, an out-of-state retailer must register with CDTFA and collect California use tax once combined California-delivered sales of tangible goods exceed $500,000 in the current or prior calendar year — a flat figure that is not indexed. For income and franchise tax, you are "doing business" in California if your California sales exceed the lesser of an FTB-indexed threshold ($757,070 for the 2025 tax year) or 25% of your total sales. We analyze your activity, determine which thresholds you cross, and file all required California returns.

At 2.5%, Arizona's flat income tax is dramatically lower than California (up to 13.3%), New York (up to 10.9%), or Illinois (4.95%). For a business owner earning $500K annually, the difference versus California alone can exceed $50K per year. Capturing that advantage depends on properly establishing Arizona domicile and structuring your business — we guide you through every step, and help you document the change so it holds up if a former state challenges it.
