1. How Does an FTB Audit Test a Claimed Move?
The FTB looks at the purpose and length of an absence, where everyday life was centered, and which California ties remained. Those facts frame whether the claimed move changed residency.
Separate Residency, Domicile, and Part-Year Status
R&TC § 17014 treats a person as a resident when present for more than a temporary or transitory purpose, or when domiciled in California but absent only temporarily. Under § 17016, more than nine months of presence creates a rebuttable residency presumption; fewer months do not prove nonresidency.
| Status | Income Generally Taxable |
|---|---|
| Resident | Income from all sources |
| Nonresident | California-source income |
| Part-year resident | All income while resident; California-source income while nonresident |

No single license, registration, or mailing address controls the result. Compare the claimed departure date with the taxpayer's state tax obligations and connections.
Trace Income That Remains Taxable after the Move
Ending residency does not end every California tax issue. R&TC § 17951 generally limits a nonresident's taxable gross income to California sources, but the sourcing rule depends on the type of income.
- Employee wages generally follow where the services were performed.
- California real property can continue producing California-source income.
- Independent-contractor and business receipts may use market-based sourcing rules.
For independent contractors, FTB guidance looks to where the customer receives the benefit of the service. Federal filing positions do not decide California residency or state sourcing.
2. Which Records Make a Residency Position Easier to Prove?
Residency audits rely on records created before and after the claimed move. A lease or new driver's license helps, but a consistent timeline is more persuasive than conflicting documents.
Build a Timeline from Everyday Records
FTB Publication 1031 describes residency as a facts-and-circumstances inquiry focused on the taxpayer's closest connections. The strength of the ties matters more than simply counting them.
- Collect leases, closing papers, moving invoices, and utility records.
- Reconcile calendars, travel receipts, and days spent in each state.
- Compare family, work, vehicle, banking, voting, and professional ties.
Retaining a former home or continuing to use California professionals does not automatically decide residency. Those facts should be explained in the context of the entire move.
Respond to Document Requests by Issue
The FTB may use an Information Document Request to gather facts relevant to the audit. Before sending records, identify the tax years, issue being tested, requested items, and response date so the production answers the question actually asked.
| Audit Question | Potential Evidence |
|---|---|
| When did the move occur? | Housing, travel, and relocation records |
| Which ties remained? | Family, property, employment, and account records |
| Where was income sourced? | W-2, 1099, K-1, contracts, and business records |

Organize the response by issue and retain proof of delivery. A focused tax audit review can help identify missing support before the FTB proposes an adjustment.
3. What Happens If the FTB Rejects the Residency Position?
The administrative path is statewide. An audit response, an FTB protest, and an Office of Tax Appeals filing are different steps. The notice title and date determine what comes next.
Protest a Notice of Proposed Assessment
If the FTB issues a Notice of Proposed Assessment, R&TC § 19041 generally gives the taxpayer 60 days from the notice date to file a written protest. The protest should identify the disputed adjustments and explain the factual and legal grounds.
- Match each argument to the affected tax year and adjustment.
- Connect residency and sourcing claims to supporting documents.
- File by the stated deadline and retain submission confirmation.
A protest does not by itself stop interest from accruing. FTB guidance separately describes payment and tax-deposit options for taxpayers who want to address interest while the dispute continues.
Separate OTA Appeals from Refund Litigation
After a protest, an adverse Notice of Action generally carries a 30-day deadline to appeal to the California Office of Tax Appeals. A denied refund claim generally has a separate 90-day OTA appeal period.
- Confirm whether the dispute concerns a deficiency or a paid refund claim.
- Preserve the record used to support the residency change and income sourcing.
- Check the notice before relying on any general filing period.
FTB guidance states that a residency refund suit after an adverse OTA decision has a special 60-day Superior Court filing period. Review state tax dispute procedures before choosing a court route.
4. Frequently Asked Questions
Does the 546-day safe harbor apply to every move?
No. It generally applies to qualifying employment-related absences of at least 546 consecutive days. Return visits generally cannot exceed 45 days in a covered tax year, and the safe harbor can fail if intangible income exceeds $200,000 or the principal purpose is tax avoidance.
Must federal tax changes be reported to the FTB?
Sometimes. When an IRS change affects California tax liability, FTB guidance generally requires notice within six months of the final federal determination.
Can stock compensation remain taxable after moving?
Yes. Compensation tied to services performed in California may remain partly or fully California-source even when payment or vesting occurs after a move.
Does keeping a California home automatically make someone a resident?
No. Property ownership is one factor among many. How the home is used, where the taxpayer spends time, and the strength of other connections also matter.
5. Review Residency Audit Records with SJKP Attorneys
A residency dispute can turn on routine dates: a lease start, workday, property closing, or trip back to California. Put those records in sequence before responding.
SJKP's attorneys can review residency evidence, income-sourcing questions, proposed assessments, and protest requirements. Contact SJKP to discuss the documents and procedural issues raised by an FTB audit.
