How is the adjusted ratio calculated in the process of determining tax ratios?

The adjusted ratio is calculated by averaging the adjusted prior year true value with the current true value. This approach is essential in the process of determining tax ratios as it provides a more accurate reflection of property values over time. By taking both the adjusted prior year values and the current year values into account, assessors can smooth out fluctuations that might occur in the real estate market from year to year. This averaging helps to ensure that the tax ratio reflects more stable valuation trends rather than potential anomalies caused by specific sales during a given year.

The other options do not accurately represent how the adjusted ratio is calculated. Simply averaging the current year's sale price with past values fails to incorporate necessary adjustments and can misrepresent the true property values. Adding all assessed values together or dividing total taxable properties by total property sales would not result in a meaningful ratio calculation in this context, as these methods do not directly relate to the assessment of true value adjustments necessary for determining tax ratios.
