For many people trying to figure out just how much passage of a $99.5 million bond issue for Enid Public Schools will cost them, it’s not as exact as just getting out a calculator.

However, property owners can get a general sense of what their property tax increase will be based on current millage levies, proposed millage levies and just adding a few numbers into what their tax bill is this year.

Enid voters will go to the polls Feb. 9 to decide a bond issue for $99.5 million to build two schools and for additional renovations to other buildings and school facilities.

A lot of components go into figuring assessed valuations and millage rate taxes property owners pay.

After the decision Tuesday night by Enid Public Schools Board of Edu-cation to call a special election for two bond proposals, Garfield County Assessor Wade Patterson said he is fielding calls from property owners about this new proposal.

He also is visiting with Enid school officials about their numbers and their debt retirement schedule.

Patterson said pro-perty tax assessments on homes don’t really change much year to year unless a home is undervalued. If a home is undervalued, the maximum assessed increase on the property would be 5 percent. However, only about 8,000 parcels of land in the entire county get that kind of assessment increase, Patterson said.

Enid property tax money currently funds four taxing entities — Garfield County, city of Enid, Autry Technology Center and Enid Public Schools. Figures presented by Enid Public Schools financial consultant Stephen H. McDonald Associates Inc. show taxpayers currently pay 97.98 mills. If the bond issue passes, the financial consultant assumes the city, county and technology center millages will remain the same, but the Enid Public Schools millage will go up 11.67 mills for 2010-2011. That would increase the total millage level for all four entities to 108.76. That amounts to a general increase of 12 percent.

There are some numbers provided by both the school district and the assessor’s office taxpayers can use to get a general sense of the cost to them for the bond issue.

An “Impact to Taxpayer” table published with this article shows projected tax amounts and monthly and annual increases based on some amounts of taxes a property owner is paying this year.

Those numbers range from a $1 monthly increase for a person paying $100 in property taxes to $10.02 monthly for someone paying $1,000 in property taxes. Carrying that table further, if someone is paying $2,000 in property taxes this year, if the bond issue passes, that person will pay $2,240 next year, and someone paying $3,000 in property taxes will pay $3,360 in 2010-2011.

Another way to figure is based on value of the home. For example, given the figures provided by the school district, if this bond issue passes, a person with a $100,000 home would pay $1,359 in property taxes next year. Bro-ken down, that would be an addition of about $160 per year, or $13 more per month, in property taxes to pay for this proposal. For a person with a $200,000 home, passing this bond issue roughly would cost that property owner another $27 a month.

Breaking it down even further, a person owning a $200,000 home would see a tax increase around 90 cents per day to fund the bond issue.
