Visit California Franchise Tax BoardCalifornia combines high graduated individual rates with aggressive residency and source-income enforcement. LLC minimum taxes and fees, the S corporation tax, payroll rules, and Franchise Tax Board administration make entity decisions materially different from federal-only planning.
This page explains planning issues rather than quoting volatile rates that may become outdated. It is designed for taxpayers deciding whether they may have a California filing, which records to preserve, and which questions to resolve before a move, transaction, or year-end deadline.

Individual, Resident & Nonresident Tax
Residents are taxed on worldwide income; nonresidents are taxed on California-source income. Residency disputes turn on facts and intent, so taxpayers leaving California need contemporaneous evidence rather than relying only on the date of a move.
Residency and source income are different questions. A person can stop being a resident yet continue filing in California for income tied to work, a business, pass-through entity, or property there. Conversely, a California resident may need another state's return and then claim a resident credit where allowed.
Business & Pass-Through Tax
California generally requires entities doing business in the state to file and pay state-level taxes. LLCs can owe the annual minimum tax plus a gross-receipts fee, while S corporations face an entity tax in addition to shareholder reporting.
Entity formation, income-tax nexus, payroll registration, sales-tax nexus, and annual reports use different standards. A company can have one obligation without the others, which is why our multi-state tax preparation process maps each tax type separately.
Sales, Gross Receipts & Local Tax
California administers sales and use tax through the CDTFA, with district taxes changing rates by location. Economic nexus, inventory, marketplace sales, and taxable products or services should be reviewed independently from income-tax nexus.
Economic nexus can arise from sales volume even without an office. Employees, contractors, inventory, events, or short-term rental activity may create physical presence sooner. Registration decisions should follow a documented nexus review—not a guess based only on where the entity was formed.
Real Estate Investor Tax Issues
California property creates California-source rental income and gain for nonresidents, and real-estate transactions may involve withholding at closing. Community-property rules, Proposition 13 assessments, depreciation, and 1031 timing all affect planning.
State tax planning should be coordinated with federal depreciation, passive activity rules, short-term rental strategy, cost segregation, and 1031 exchange planning. The state cash requirement at closing may differ from the final tax shown on the return.
Moving, Remote Work & Multistate Income
Remote employees, California customers, management activity, and California-based owners can create filing exposure for an out-of-state business. California sourcing does not always follow where the company was formed or where payment arrived.
Preserve calendars, travel records, employment agreements, closing statements, leases, driver's-license and voter records, payroll reports, and evidence of where management decisions occurred. Consistent facts make residency and sourcing positions easier to defend.

Does California have an individual income tax?
Graduated individual income tax. Residents are taxed on worldwide income; nonresidents are taxed on California-source income. Residency disputes turn on facts and intent, so taxpayers leaving California need contemporaneous evidence rather than relying only on the date of a move.

Yes. Simply Smart Tax Advisors is based in Temecula, California and works virtually with business owners and real estate investors nationwide. Samera Harvey is an IRS Enrolled Agent with unlimited federal practice rights before the IRS. State-agency representation rules can differ, so we confirm the permitted scope and coordinate with local counsel when a matter requires it.
When does a nonresident need a California tax return?
A nonresident may need a return when income is sourced to California, including income from work performed there, a business operating there, or real estate located there. Remote employees, California customers, management activity, and California-based owners can create filing exposure for an out-of-state business. California sourcing does not always follow where the company was formed or where payment arrived.
Where can I verify current California tax rules?
Use the California Franchise Tax Board as the primary state source. Tax rates, thresholds, forms, and election deadlines change, so this planning guide should be paired with current official instructions and advice based on your facts.
