Idaho Code § 72-701
No proceedings under this law shall be maintained unless a notice of the accident shall have been given to the employer as soon as practicable but not later than sixty (60) days after the happening thereof, and unless a claim for compensation with respect thereto shall have been made within one (1) year after the date of the accident or, in the case of death, then within one (1) year after such death, whether or not a claim for compensation has been made by the employee. Such notice and such claim may be made by any person claiming to be entitled to compensation or by someone in his behalf. If payments of compensation have been made voluntarily or if an application requesting a hearing has been filed with the commission, the making of a claim within said period shall not be required.
