Kalawao County, HI follows the Hawaii statutory schedule. This page shows that schedule, the county's own website, and the late penalty — the county can still set its own dates, so confirm before you pay.
| Instalment | Due date | Notes |
|---|---|---|
| 2nd half | February 21, 2027 | Second installment, billed separately by January 20. |
| 1st half | August 21, 2027 | First installment of the July 1–June 30 tax year, set by county ordinance. |
A penalty of up to 10% plus interest (12% a year on Oahu) is added to an installment not paid by its due date.
Annual bills are mailed by July 20 for the fiscal year that starts July 1, and second-half bills are mailed by January 20.
Not yet. Kalawao County is on the queue: we publish a county's own published dates once they have been checked against the county website. Ask for it and it moves up. Until then, the Hawaii statutory schedule above is the reliable starting point.
