TL;DR — Key Takeaways
- →California uses a facts-and-circumstances domicile test. Nights outside the state do not by themselves end residency.
- →Track license, voter registration, banks, employer, property, and social ties with the day count.
- →A safe-harbor style exit usually means the strong California ties are actually cut, not only that travel increased.
- →Keep the log as you go. Reconstructing a year from email is a weak record.
Short answer
A California leaver should log domicile factors as carefully as nights in the state. The Franchise Tax Board looks at where your closest connection remains. Days present matter, but they are not the whole test.
Facts worth dating
- Driver's license and vehicle registration
- Voter registration
- Bank and brokerage accounts
- Where you work, and where your employer thinks you are based
- Real property you own or rent in California
- Doctors, clubs, and family ties you kept after the move
Write the date each tie changed. A checklist with no dates is hard to defend later.
