The Geographic Arbitrage: Tax Migration & Domicile Planning

Moving from California or New York to Florida or Texas isn’t just a U-Haul trip; it’s a legal battle. How to sever your “Sticky Domicile” and survive the residency audit.

Executive Summary

  • The SALT Cap Pain: High earners in states like California (13.3% top rate) or New York (10.9%+) lose massive wealth annually. Since the SALT deduction is capped at $10k, this is a pure loss. Moving to a **0% Income Tax State** (FL, TX, NV, TN, WA, WY, SD) is the equivalent of an immediate 13% raise.
  • The “Sticky Domicile” Risk: States do not let rich taxpayers leave easily. California’s FTB and New York’s DTF conduct aggressive **Residency Audits**. They track cell phone towers, credit card swipes, and flight logs to prove you never “really” left.
  • The Strategy (Clean Break): You cannot just “buy a condo” in Miami. You must prove you **abandoned** your old domicile. This means moving your “Teddy Bears” (items near and dear to your heart), changing doctors, moving pets, and spending <183 days in the old state.

The “Teddy Bear” Test

The Auditor’s Psychology: Auditors don’t look at where you vote; they look at where you *live*.
👉 The Rule: If you move to Texas but leave your wedding photos, expensive wine collection, family dog, and heirlooms in your California house, **you have not moved.** You are just “visiting” Texas. You must move the emotional center of gravity of your life.

“In the eyes of the taxman, you can have many houses, but only one ‘Home.’ The burden of proof is on you to show that your old home is now just a ‘vacation property’ and your new house is your ‘castle.'”
