Tax Calculations

Your property taxes are calculated using three factors:

1)      Value of your property as determined by the county auditor.

      a) Your property was revalued by the county auditor during the 2013 
          Reappraisal. Please be aware that a decrease in property value does not
          result in a comparable decrease in property taxes due to the HB 920 tax
          reduction factor. The Auditor changes property values every 3 years, either
          during a reappraisal or triennial update. During the reappraisal, each parcel is
          visited to ensure that the record of the property is accurate. The value of
          the property is then established by comparable sales. The triennial update
          adjusts values based on sales only. Properties are not visited during the
          update cycle.  Values will change outside of the 3 year cycle for new
          construction, demolition, or the result of a Board of Revision Hearing.

      b) Reappraisal and Triennial Update Schedule for Ohio’s 88 Counties

2)      Tax rate established in your community.

       a)  Tax rates change when the voters within a community approve new levies.

3)      Tax reductions, credits and rollbacks established by Ohio law.

       a)  The HB 920 reduction factor, mandated by Ohio law, is designed to
           keep tax revenues stable when property values increase or decrease.

This example assumes your home has a fair market value of $100,000.

Market value x 35% = assessed value $100,000 x .35 = $35,000
Assessed value x full rate = gross tax $35,000 x .06705 = $2,346.75
Gross tax x reduction factor = tax credit    $2,346.75 x .313622 = $735.99
Gross tax - tax credit = tax before credits  $2,346.75-$735.99 = $1,610.76
Tax before credits x Non-Business Credit = Non-Business Credit $1,610.76 x .098913 = $159.32
Tax before credits x Owner Occupancy Credit = Owner Occupancy Credit $1,610.76 x .024728 = $39.83
Tax before credits-(10% + 21/2%) = Net Tax $1,610.76-$159.32-$39.83=$1,411.60
Net tax charged divided by 2 = Half Tax  $1,411.60/2 = $705.80

 (Orange Township tax rate used for this example.  This example assumes no special assessments and is based on an “owner occupied” residential property.  Additional homestead exemption credit could apply if over 65 or totally disabled.)

Overview of the Process

Taxes are based on the parcel’s market value and the levies passed by the voters. After the market value is established by the Auditor, a final Abstract of Values must be submitted to the state for approval. Upon approval, the state issues the new tax rates for the next tax year based upon the new values, levies voted on by the taxpayers, and the non-voted 10 mills. If property values increase, the state makes adjustments called "reduction factors" which prevents the levies from generating more revenue than what was voted into law.

After the final market value is established the individual real estate parcels are then taxed on 35% of the market value. This 35% is called the assessed or taxable value. The assessed value is multiplied by the tax rate for your school district. The "reduction factor" for your taxing district subtracts the excess that would have been generated over and above the allowable millage.

Most residential parcels also qualify for the 10% rollback on taxes based on legislation enacted in 1971. This rollback does not apply to commercial or industrial properties.

Residential parcels where the home is owner-occupied may also qualify for the Owner Occupancy reduction in taxes on their dwelling, up to a one acre home site.

The millage generated by the county is applied to the general fund, roads, Carroll County Board of Developmental Disabilities, Senior Citizens, and Carroll Golden Age Retreat. Revenue generated from levies for various Townships, Municipalities, and Schools are appropriately distributed as well.

How Much Will My Taxes be Lowered if My Value is Lowered in the Update?

Sales are reviewed and any necessary adjustments are made. Please be aware that even if the parcel value decreases, your taxes might not be lowered.

Tax rates for emergency levies for school districts and bond retirement rates are adjusted each year to generate a set level of revenue. As values increase, the tax rates for these levies are often adjusted downward. The reverse is also true. As values decline in a district, these tax rates are adjusted upward in order to generate a specific amount of revenue.

The second reason taxes may not be reduced is because the State Tax Commissioner recalculates what are called “reduction factors” for the voted tax levies each year. This legislation was passed in the 1970s to prevent taxing entities from receiving windfalls from rapidly rising property values. On most voted levies, if property values go up, the effective taxing rate goes down to keep revenue constant. In today’s market, with values declining in some areas, that same provision can increase the effective millage rates so that the taxing entity does not incur a shortfall. As property values decline, the effective tax rates will increase in order to keep revenue constant.

However, there is a limit. Effective millage cannot be increased to more than the original millage set by voters. So a taxing entity cannot compensate for lost revenue without enacting new taxes or budget cuts.
