Bill > A05871

This bill requires local government assessment units to increase transparency in how they calculate property tax assessments by mandating annual online disclosures about their assessment methods. For assessment units using computer-assisted mass appraisal (CAMA) systems or statistical formulas, they must publish detailed information including: the specific statistical formulas used, a description of each variable in those formulas, the data sources for those variables, a written explanation of how calculations determine property assessments, and details about the computer software such as its usage duration and licensing costs. For assessment units that do not use such computerized systems, they must instead publish an annual verification stating they do not use such systems and provide an explanation of their manual assessment methods. The purpose of the bill appears to be increasing transparency and allowing property owners to better understand how their property tax assessments are calculated. The bill will take effect 90 days after becoming law.
