By what date should the municipality's tax assessor adjust property tax records for changes?

The correct answer indicates that the municipality's tax assessor should adjust property tax records for changes on an ongoing basis throughout the year. This approach is essential because property conditions, ownership, and classifications can change at any time, necessitating continuous updates to ensure that tax assessments are accurate and reflect the current status of the property.

Ongoing adjustments allow the assessor to account for various events such as new construction, renovations, changes in use, or ownership transfers without waiting for a specific date. This practice helps maintain the integrity of the tax records and ensures that assessments are fair and equitable.

In contrast, the other choices suggest specific deadlines that could limit the assessor's ability to keep the records accurate and up-to-date. By relying on an ongoing process, municipalities can better manage their tax assessments in real-time, providing a clearer and more accurate reflection of property values throughout the tax year.
