Do you sell real property for taxes owed?

Real property cannot be sold for the dollar amount owed in back taxes. However, if the taxes owed are two years delinquent and a payment plan has not been followed to bring the taxes current, the property may be sold at Sheriff's sale by the Treasurer, for 2/3 of the appraised value, unless the taxpayer has filed bankruptcy protection. Tax lien sales are not conducted in Seneca County.

Example: If a property is worth $100,000.00 and there are taxes due for $5,000.00, we cannot sell the property for $5,000.00.

There are two amounts listed on the bill. Which one do I pay?

In February, you may choose to pay only the first half or the whole year. If you pay the whole year, you will not receive another bill until January of the next year.

Tax Calculation

The steps outlined below show how a real estate tax bill is calculated. The calculations used in the example are for a $100,000 home in Allen Township for tax year 2005; Full tax rates and reduction factors can be found on the tax rate sheet above.

Note: 10% rollback does not apply to commercial property.

Determine the assessed value:

Formula: (Appraised Value) x 35% = Assessed Value

Example: $100,000 x .35 = $35,000

Divide (Assessed Value) in half to Calculate Half-Year Tax Bill Amount:

Formula: (Appraised Value) / 2 = Assessed Value (For Half-Year Tax Bill Calculation)

Example: $35,000 / 2 = $17,500

Calculate the gross tax [See the tax rates above for full rates.]:

Formula: (Assessed Value) x (Full Rate) = Gross Tax (for Half-Year) / 1,000

Example: $17,500 x 83.60 / 1,000 = $1,463.00

Calculate the reduction factor credit amount [See the tax rates above for reduction factors.]:

Formula: (Gross Tax) x (Reduction Factor) = Reduction Factor Credit

Example: $1,463.00 x .452516 = $662.03

Reduce the gross tax by the reduction factor credit amount:

Formula: (Gross Tax) - (Reduction Factor Credit) = Adjusted Tax

Example: $1,463.00 - $662.03 = $800.97

Calculate the rollback credit amount:

Formula: (Adjusted Tax) x (Rollback) = 10% Rollback Reduction

Example: $800.97 x .10 = $80.10

For "Owner-Occupied" Residential Properties, there is an additional 2.5% Rollback:

Formula: (Adjusted Tax) x (Rollback) = 2.5% Rollback Reduction

Example: $800.97 x .025 = $20.02

Reduce Adjusted Tax by Total Rollback for Half-Year Tax Amount:

Formula: (10% Rollback) + (2.5% Rollback) = Total Rollback Reduction (Adjusted Tax Amount) - (Total Rollback Reduction) = Total Half-Year Tax Amount.

Example: $80.10 + $20.02 = $100.12

$800.97 - $100.12 = $700.85

Half Year Tax Amount: $700.85 Billed Semi-Annually

Tax Language

Real Estate Tax

Real Property tax is one of the oldest taxes in the State of Ohio and is also one of the most stable tax bases, the taxable value of land and buildings. Tax rates vary between tax districts depending on all levies approved either by legislative authority or by the voters in the district. Ohio law limits local government authority to assess property taxes by creating the 10 mill limitation.

Tangible Personal Property

Personal property tax originated as a tax on farm inventories and equipment and until 1931 personal property and real property were taxed together. The tax base is the inventory, equipment and machinery used in business in Ohio. Personal property is taxed at full rates as no reduction factors are applied to personal property.

Manufactured Home Tax

Similar to the above property taxes, MFG Home Taxes were instituted in 1925 with the development of Manufactured Homes. The tax base is 40% of the depreciated value of the home and the rate is the total of all taxes levied in the district. New law passed by the Ohio General Assembly in December of 1998 significantly changes Manufactured Home taxation by assessing the value of the home similar to Real Estate, at market values.

Estate Tax

The State of Ohio is the administrative agent for Ohio's Estate Tax, however, depending on the county of residence of the decedent, the County Treasurer collects the tax locally, distributing twice a year 30% of the collection to the state, less fees, and the remaining balance distributed to the local tax districts allocated on a percentage of where the estate assets were held.
