Why This Guide Exists
I help California families relocate to the Texas Hill Country. The single most common question I hear — before school districts, before home prices, before anything else — is some version of: "Will California keep taxing me after I leave?"
The short answer is: California has no "exit tax" in the way most people imagine it. But California does retain significant rights to tax former residents on certain income and gains, and the Franchise Tax Board (FTB) is aggressive about enforcing them. Understanding these rules is not optional — it is the foundation of a clean, financially sound move.
This guide covers the six topics every California-to-Texas relocator needs to understand before filing their last California return. Each section is written to stand alone, but they are deeply interconnected. The residency determination in Section 4 affects everything in Sections 1 through 3. The CPA questions in Section 6 apply to all of it.
What California Can — and Cannot — Tax After You Leave
California taxes based on residency. If you are a California resident, you owe California income tax on all income, no matter where it is earned. If you are a nonresident, California can only tax you on California-source income. The critical question is: when does California consider you a nonresident, and what counts as California-source income?
Texas has no state income tax. Once you are genuinely a Texas resident earning Texas-source income, California has no claim on that income. But the transition period — the year you move, the months after you leave, and any income tied to California assets — is where complexity lives.

Read moreThe Bottom Line
California is one of the most aggressive states in the country when it comes to taxing former residents. The FTB conducts hundreds of residency audits every year, and they have a four-year statute of limitations — or indefinitely if you fail to file a return. But none of this should scare you out of making a good move. It should simply motivate you to do the move correctly.
The people who get into trouble are the ones who move to Texas but keep their California driver's license, keep voting in California elections, maintain California bank accounts as their primary accounts, and spend most of their time in California. The FTB looks at the totality of your connections, not just where you sleep at night.
The people who move cleanly — who establish genuine Texas ties, update their documents, file their homestead exemption, and maintain records of their physical presence in Texas — rarely face issues. That is what the checklist in Section 5 is designed to help you do.
If you are planning a move, start with a conversation with a CPA who understands both California and Texas tax law. Then use this guide as a reference as you execute your plan.
