HRS §231-17
When tax notices are considered given
This section says that when the tax department sends you a notice by mail, it counts as given on the day it is mailed, not the day you receive it. It applies unless another law says otherwise. The notice must be sent to your last known address or workplace.

The statute, as written — Notices, how given
Unless otherwise provided, every notice, the giving of which by the department of taxation is required or authorized, shall be deemed to have been given on the date when the notice was mailed, properly addressed to the addressee at the addressee's last known address or place of business.
