Before you start · 4 things to check

Choose the county collector for your bill and payment method; the BOE and State Controller entries are shared state information, not local offices.
A due date and a delinquency date differ. Check the regular secured-roll calendar, the next-business-day rule, your bill type and the exact payment-channel cutoff.
The homeowners’ exemption reduces taxable assessed value. Proposition 19, supplemental bills and postponement each have separate conditions and filing rules.
