Estimate a specified late charge only where a cited structured rule supports the calculation.

Orange County, CA

First installment payments after December 10 incur a 10% penalty.

Official penalty rule

First secured installment only, after the published December 10, 2026 delinquency cutoff. Other charges and later tax-default costs are excluded.

Rule last verified 2026-10-24

Example: $100.00 charge on a $1,000 unpaid installment, one day after the stated cutoff. This is the specified charge only, not a payoff quote.

Confirm the applicable cutoff and any extensions with the county. Enter the number of days or chargeable months the county uses. This calculates only the cited charge, excluding collection costs, other interest, fees and special arrangements.
