What action must be taken within 45 days regarding complaints about added assessments?

Filing a complaint with the Tax Court within 45 days is the required action when a taxpayer disagrees with added assessments in New Jersey. This timeframe is crucial because it reflects the statutory requirements set forth in state laws, which allow taxpayers the avenue to challenge the assessment formally. By filing with the Tax Court, individuals ensure their grievances are addressed in a legal setting where evidence can be presented, and a fair determination can be made.

The other options involve different processes or incorrect timelines related to property assessment and appeals. Seeking a reassessment is typically not the recommended immediate action following an added assessment. Notifying the County Board could be a part of the appeals process, but it doesn't directly challenge the assessment within the 45-day window. Withdrawing an appeal is a choice made after a complaint is filed if further action is no longer desired, which does not apply to addressing the initial added assessment complaint. Thus, the requirement to file with the Tax Court is not only a specific action to take, but it also symbolizes the structured approach to property tax disputes in New Jersey.
