All 58 California counties and county equivalents. 11 have been checked against the county's own schedule; the rest follow the state schedule below.
| Instalment | Due | Notes |
|---|---|---|
| First installment | November 2, 2026 | First installment; a 10% penalty applies if unpaid after December 10. |
| Second installment | February 2, 2027 | Second installment; a 10% penalty applies if unpaid after April 10. |
California property tax is billed and collected county by county, so the collector — not the state — issues the bill. All 58 counties use the same November 1 and February 1 due dates and December 10 and April 10 delinquency dates.
