1. FTB vs. CDTFA vs. EDD
Three main California tax agencies with different jurisdictions.
If this is you: Uncertain which agency handles your tax matter. FTB for income and franchise tax. CDTFA for sales, use, and similar business taxes. EDD for payroll and employment tax.
Identifying Your Agency
- Identify tax type.
- Match to agency jurisdiction.
- Confirm via notice.
- Check for overlap.
- Engage appropriate counsel.
2. California’s 20-Year Collection Statute
RTC §19255 gives FTB 20 years from assessment to collect.
If this is you: Wondering when California tax becomes unenforceable. 20 years from assessment, far longer than federal 10-year CSED.
3. California Residency Rules
Residency determination drives state income tax liability.
If this is you: Moved out-of-state or questioning residency status. 9-month presumption, domicile, closest connection tests.
4. California / Federal Tax Interaction
Extensive information sharing between California and federal agencies.
If this is you: IRS audit or FTB audit. Findings at one level often flow to the other. Coordinated representation preferred.

Frequently Asked Questions
What are the California state tax agencies?
Three main agencies. FTB handles state income and franchise tax. CDTFA handles sales, use, cannabis, fuel, and similar business taxes. EDD handles payroll and employment tax. Office of Tax Appeals hears contested matters independently.
How long can California collect?
20 years from assessment under RTC §19255 for FTB income tax. Other agencies have similar or different periods. Substantially longer than federal 10-year CSED. Long planning horizon for California tax resolution.
What is California residency for tax purposes?
Primary test under RTC §17014: domicile (permanent home) or more than 9 months in California creates presumption of residency. Complex tests for dual-state situations. Fact-intensive analysis.
Does California tax share information with IRS?
Yes, extensively. Federal adjustments flow to California; California adjustments produce federal inquiries. Coordinated representation recommended for material matters.
Can I move to avoid California tax?
Yes if moving terminates residency under RTC §17014. Complex documentation required. FTB pursues residency audits aggressively on high-income taxpayers claiming non-residency.
Does FTB have an OIC program?
Yes. Form FTB 4905. Similar to IRS OIC but with narrower acceptance. See FTB OIC chapter.
Can bankruptcy discharge California tax?
For eligible older income tax, yes. Similar tests to federal. Franchise tax (minimum $800) typically not dischargeable. Specific bankruptcy analysis required.
What is the CA Office of Tax Appeals?
Independent body established in 2018 to hear contested California tax matters. Three-member panels. Replaced Board of Equalization’s adjudicative function. Hears appeals from FTB, CDTFA, and other agencies.
Does California tax retirement income?
Generally yes for residents. Specific exemptions for railroad, military, and certain federal retirement. Non-residents typically not taxed on California-source retirement.
What is California’s minimum franchise tax?
$800 annually for California corporations, LLCs, and LLPs. Must be paid even with no income or losses. Failure triggers corporate suspension.
Can California tax my out-of-state business?
Yes if you have California nexus — physical presence, economic nexus (post-Wayfair), or marketplace facilitator. See multistate tax guide.
Does California have an estate tax?
No current California estate tax. California decoupled from federal estate tax. Federal estate tax may still apply to large estates.
How do I handle California and federal audits together?
Coordinated representation. Understand each agency’s procedures. Manage information flow between them. Representation by attorney familiar with both systems.
