Colorado County Auditor Raymie Kana said she is preparing county commissioners for the possibility of an increase in the county’s tax rate of 1.77 cents to bring in the same amount of property tax revenue as last year for properties taxed in both years.

The increase would bring the tax rate to 48.206 cents per $100 valuation.

That would be the effective rate to bring in the same amount of property tax revenue as last year, comparing property taxed in both years.

Kana said that would offset a decline in property tax revenue projected from a decrease in the county’s adjusted tax roll of $40.7 million.

The Colorado County Appraisal District certified the county’s tax roll last week at $1.610 billion, a decline of 1.95 percent from 2009 certified roll.

While the final certified tax roll is down by $32 million from the certified roll in 2009, Kana said the final 2009 tax roll after adjustments was $1.651 billion.

Commissioners have not addressed the tax rate yet because the county has been waiting on final figures from the appraisal district.

Oil and gas values in the county declined $65 million, according to figures from the appraisal district.

Final figures on most of the values from the various taxing agencies are in line with earlier preliminary estimates from the appraisal district.
