The first bill has a due date and a later deadline
The first installment was due on 1 November 2026. The county says the installment becomes delinquent if payment has not been received or USPS postmarked by 10 December 2026. A taxpayer can pay both installments together or separately. Source 1 Source 3
The Saturday in April moves the second deadline
The second installment is due 1 February 2027. The county’s normal 10 April delinquency date falls on Saturday that year. The county says a weekend delinquency date moves to the close of business on the next business day, which gives Monday 12 April 2027 under that rule. Source 2 Source 3
Check the payment channel and postmark
The county explains receipt and postmark rules and warns that the USPS postmark may differ from the day an envelope is put in a mailbox. Its guidance lists separate payment methods and instructions. Check the date on the bill and follow the instructions for the payment method used. Source 3
Delinquency and default bring different charges
The county adds a 10% penalty on an unpaid installment balance after the delinquency date. It also lists a USD 10 notice cost on the second installment. Unpaid current-year amounts become defaulted on 1 July if payment is not received or USPS postmarked by 30 June. The county then lists separate redemption charges. Source 3
