When notifying the public about tax assessments, which method is NOT commonly included in reasonable notice?

The answer is focused on the most efficient and practical methods of providing public notification about tax assessments. Personal phone calls are typically not a standard method of notifying a large public audience due to their individual and time-consuming nature. Unlike broadcasting via newspapers, websites, or radio announcements, which can reach a wide audience simultaneously, personal phone calls would require significant resources and effort to contact each individual, making them an impractical choice for mass communication.

In contrast, the other methods listed—posting on a website, using newspapers, and radio announcements—are widely recognized as effective means of disseminating information to the public. Websites can quickly disseminate updates and can be accessed by a broad audience at any time. Newspapers have long been a traditional method for public notices, ensuring that the information reaches community members who may not have internet access. Radio announcements leverage auditory communication to reach listeners during broadcasts, which is particularly beneficial for reaching individuals who may not read newspapers or browse online.

Therefore, relying on personal phone calls does not align with commonly accepted practices for reasonable notice regarding tax assessments, making it the correct choice.
