How To Survive A California Residency Audit
Key Takeaway
Surviving a California residency audit requires four focus areas: (1) documented severance of California ties; (2) established domicile in new state; (3) comprehensive timeline with supporting evidence; and (4) strategic response to FTB IDRs. The short version is that residency audits are fact-intensive. FTB examines every connection to California. Clean documentation of the move and residence in new state is the primary defense.1

Frequently Asked Questions
How do I survive a California residency audit?
Four areas. Documented severance of CA ties. Established new domicile. Comprehensive timeline. Strategic IDR response. Professional representation typical for material cases.
What triggers CA residency audit?
High-income taxpayer claiming non-residency. Continuing CA ties. Significant CA-source income. Recent relocation. FTB statistical flagging.
What ties matter most to FTB?
Primary residence location. Family location. Driver’s license. Voter registration. Professional licenses. Bank accounts. Medical providers. Business operations. Each individually evaluated and combined in closest connection analysis.
How do I prove non-residency?
Comprehensive documentation. Moved family. New state residence. New driver’s license. Voter registration. Vehicles registered. Banking moved. Employment transferred. Medical providers. Time in CA documented as temporary.
Can I keep CA property and claim non-residency?
Yes if evidence supports non-residency. Maintaining CA rental or vacation property does not automatically establish residency. But primary residence status must be elsewhere.
How long does CA residency audit take?
6 to 24 months typical. Complex multi-year audits longer. Appeals add additional time.
Does FTB track my location?
Through records — cell phone tower, credit card transactions, travel bookings, social media. FTB can build presence timeline from multiple data sources.
What is the CA residency questionnaire?
FTB document requesting detailed factual information — homes, travel, banking, family, employment, professional relationships. Initial tool in residency audit.
Can I appeal residency finding?
Yes. Protest within FTB, OTA review, Superior Court. Fact-intensive appeals frequently produce material changes.
Is FTB aggressive on residency?
Yes for high-income taxpayers. California tax revenue at stake motivates thorough audits. Expect rigorous examination of every connection.
What is 'closest connection' for residency?
Multi-factor analysis comparing connections to CA vs. other state. Home, family, business, community ties. State with more / stronger connections is residency state.
Can I move and come back frequently?
Risky. Frequent return visits to CA can support continuing residency. Under 9 months presence helps; greater than 9 months creates residency presumption.
How do I document a move?
Timeline with specific dates. Moving van receipts. New home purchase / lease. Driver’s license change. Voter registration. Utilities in new name. Family school records. Comprehensive paper trail.
