Property-tax bills are made up of about a dozen different increments from five taxing jurisdictions: state, county, school district, community college and municipality.

The rate imposed by a jurisdiction typically is less than the final rate certified by the state Property Tax Division because of an algorithm called the yield control formula — a system intended to prevent windfalls for government when property values increase.

Final numbers on tax rates aren't released until the county assessor completes an annual process of assigning values to homes, businesses and land.

Both city officials and private citizens with an interest in the issue have performed calculations about the potential effect of a proposed city property-tax increase.

Here's an example, using a home with a full value of $300,000:

Since taxes are levied on one-third of full value, the home's taxable value is $100,000. The city's portion of the tax bill in 2010 was $177.20. If the city increased its operational mill rate by 1.16 and all other factors stayed the same, the city's portion of the same home's tax bill in 2011 would be a maximum of $293.20, or an increase of about $116 in a year.

The county assessor reports that the 26,055 residential properties in the city of Santa Fe have a combined value of $2.7 billion. The average full value of a home is $314,016, making the average taxable value $104,672.
