Property Taxes
Determining Entities
The property tax rate for residents in Sioux Center is determined by four entities:
- City of Sioux Center - Receives approximately 32.8% of the total property tax bill
- Northwest Iowa Community College - 3.2%
- Sioux Center Community School District - 52.2%
- Sioux County - 11.8%
The governing boards and councils of each of these entities determine their own tax rate each year. The four rates are then consolidated to determine the property tax owed by each property owner within the Sioux Center city limits. This consolidated rate is then multiplied by the assessed property valuation of each parcel of property. The assessed valuation of each parcel is determined by the Sioux County assessor's office.
Residential Property Owners
For residential property owners, the state legislature has instated a rollback in tax bill calculation. This reduces the actual valuation of residential property to approximately 52% before being multiplied by the consolidated tax rate.
Below is an example of the property tax bill calculation for a Sioux Center home valued at $150,000.
| Residential Home Value | Rollback Percentage | Taxable Valuation | Tax Rates (per $1000 Valuation) | Property Taxes Paid to each Entity | |
|---|---|---|---|---|---|
| $150,000 | x 54.13% | = $81,195 | x 17.70016 (School) | = $1,437 | To School |
| $150,000 | x 54.13% | = $81,195 | x 11.13499 (City) | = $904 | To City |
| $150,000 | x 54.13% | = $81,195 | x 3.99606 (County) | = $324 | To County |
| $150,000 | x 54.13% | = $81,195 | x 1.07258 (Comm. College) | = $87 | To Community College |
| Total Tax Rate | 34.90379 | $2,752 | Total Property Taxes Owed | ||
Commercial / Industrial Property Owners
The Iowa state legislature does not give the rollback to commercial and industrial property owners.
Below is an example of the property tax bill calculation for a commercial property valued at $150,000.
| Property Value | Rollback Percentage | Assessed Valuation | Tax Rates (per $1000 Valuation) | Property Taxes Paid to each Entity | |
|---|---|---|---|---|---|
| $150,000 | x 90% | = $135,000 | x 17.70016 (School) | = $2,390 | To School |
| $150,000 | x 90% | = $135,000 | x 11.13499 (City) | = $1,503 | To City |
| $150,000 | x 90% | = $135,000 | x 3.99606 (County) | = $539 | To County |
| $150,000 | x 90% | = $135,000 | x 1.07258 (Comm. College) | = $145 | To Community College |
| Total Tax Rate | 34.90379 | $4,577 | Total Property Taxes Owed | ||
