Guidelines for Annual Reassessment

Overview

Benefits of Annual Reassessment
Each year, State Law requires assessors to sign an oath that the assessments in their municipality represent a uniform percentage of market value. The best way to ensure that assessments are consistently fair and equitable is keep assessments up-to-date annually. To encourage compliance with State law, New York State provides State Aid of up to $5 per eligible parcel to municipalities that keep assessments at 100% of market value each year. For special assessing units, uniformity must be maintained within each class. Aside from State Aid, the benefits of maintaining consistent market value assessments include:

The information contained in this booklet provides guidelines for planning the process of maintaining equitable assessments and can help local officials understand the scope of tasks involved in this process.

Statutory Requirements
New York State Real Property Tax Law (RPTL) actually requires annual assessment of all properties:

Properties need not be assessed at 100 percent of value provided they are assessed at the same uniform percentage throughout the assessing unit (throughout each class in New York City and Nassau County).

To encourage compliance with State Law, Section 1573 of the RPTL provides an incentive payment of up to $5 per parcel (also known as "State Aid") for cities and towns assessing at a level of assessment of 100 percent. In New York State’s two "special assessing units", Nassau County and New York City, assessments within a property class must be confirmed as reflecting the assessor’s stated level of assessment in order to receive State aid. In order for property to be assessed consistently at a uniform percent of current market value, a “reassessment” must be conducted each year.

Terms and Definitions
According to statute, a reassessment is "a systematic review of the assessments of all locally assessed properties, valued as of the valuation date of the assessment roll containing those assessments to attain compliance with the (statutory) standard of assessment" (Real Property Tax Law – Section 102). It is synonymous with the terms "revaluation" and "update".

IAAO Standards
ORPS’ program of annual aid for maintaining equity is guided by the standards for assessment administration published by the International Association of Assessing Officers (IAAO). The two specific statements of the IAAO below are applicable to the annual assessment of property.

The Principle of Annual Reassessment
Current market value implies annual assessment of all properties. This does not necessarily mean that every property must be appraised each year. In annual assessment, the assessing officer should consciously re-evaluate the factors that affect value, express the interactions of those factors mathematically, and use mass appraisal techniques to estimate property values. Thus, it is necessary to observe and evaluate, but not always to change, the assessment of each property each year to achieve current market value. It is recommended that assessing officers consider establishing regular reappraisal cycles or at least quality (vertical and horizontal equity) thresholds that trigger reappraisal. (Standard on Property Tax Policy [Paragraph 4.2.2.], approved August 1997).

Frequency of Reappraisals
Properties should be revalued annually. Annual assessment does not necessarily mean, however, that each valuation must be reviewed or re-computed individually. Instead trending factors based on criteria such as property type, location, size, and age can be developed and applied to groups of properties. These factors should be derived from assessment-ratio studies or other market analyses.

The analysis of assessment-ratio studies data can suggest groups or strata of properties in need of physical review. In general, trending factors can be highly effective in maintaining equity when appraisals are uniform within strata. Physical reviews and individual reappraisals are required to correct lack of uniformity within strata.

While assessment trending can be effective for short periods, properties should be physically reviewed and individually appraised at least every six years. This can be accomplished in at least three ways: (1) reappraising all properties at periodic intervals (e.g. every four to six years); (2) reappraising properties on a cyclical basis (e.g., one-fourth or one-sixth each year); and (3) reappraising on a priority basis as indicated by assessment-ratio studies or other considerations, while ensuring that all properties are physically reviewed at least every sixth year. (Standard on Mass Appraisal of Real Property [Paragraph4.5], approved March 1984.)

Simply stated, the IAAO supports annual assessment of all property at market value. This annual valuation can be achieved by analyzing the assessments of all properties with respect to the current market, and revising assessments of individual properties or groups as necessary, either by individual reappraisals, "trending" the assessments of groups of properties, or some combination of both, while at the same time ensuring that all properties are reappraised and re-inspected at least once every six years.

ORPS' Programs Recognizing Reassessment Activity
The following ORPS' programs recognize reassessment activity:

For an assessing unit to participate in each of these programs, ORPS must analyze and understand the local reassessment activity. This analysis does not require active participation or support by the Agency in the reassessment project. While the analysis may indeed take the form of monitoring reassessment activity as our staff members assist in the course of a project, it may also take the form of our staff reviewing the municipal processes and procedures at specific intervals during the project. It is our intent that by working collaboratively, we can ensure a common understanding of ORPS’ standards and expectations and provide the opportunity to avert potential problems and eliminate misunderstandings before they occur. This process is commonly referred to as Pre-Decisional Collaboration (PDC).

State Aid Requirements

Section 1573 of the RPTL allows for a payment of up to $5 per parcel annually. In order to be eligible to receive this aid, an assessing unit must:
