An FTB audit is commonly triggered when California tax filings contain inconsistencies, missing income, unusual deductions, or reporting differences compared to federal tax returns. Businesses and individuals with unresolved state tax liabilities or incomplete filings may also face increased audit attention from the California Franchise Tax Board.
Underreported California income is one of the most common audit triggers. The FTB closely reviews tax returns involving business income discrepancies, excessive deductions, missing California tax returns, and large unpaid tax balances. Federal and state filing inconsistencies may also raise concerns when reported income, deductions, or financial disclosures do not match between IRS and California tax records.
Residency disputes are another major focus area during California tax audits. The FTB may examine whether individuals properly reported California residency status, especially when taxpayers claim residency in another state while maintaining financial or business connections within California. Crypto reporting issues and digital asset transactions may also increase scrutiny when taxable gains are not fully reported.
Payroll inconsistencies, inaccurate bookkeeping, and unsupported financial records may further increase audit exposure for businesses. Maintaining organized tax documentation, accurate filings, and complete financial records plays an important role in reducing California audit risks and strengthening long-term tax compliance.
FTB audits review California income reporting, deductions, residency status, financial records, and potential state tax compliance discrepancies.
