We hope these FAQ give you a better idea of the work we do and how it relates to the overall property tax structure. We believe the public has the right to know what we do and how we do it. Please feel free to contact our office if you would like further clarification on any point or if you have any other questions.

Both seller and buyer owe property taxes for the period of time they own the property. 35 ILCS 200/9‑180 explains that owners of property shall be liable, on a proportionate basis, for the increased taxes occasioned by the construction of new or added buildings, structures or other improvements on the property from the date when the improvement was substantially completed or initially used to December 31st of that year. This allows for the owners and occupant of new construction to pay taxes for the value of their property for the part of the year that it was owned, completed, and occupied. The Supervisor of Assessments Office can answer any further questions on this subject by calling (815) 319-4460.
The assessor has no control over the tax rate. The County Clerk’s office is responsible for calculating real estate tax rates for all taxing districts within Winnebago County. There more than 100 taxing districts, which receive property tax revenue. Additionally, local citizens can influence spending by voicing their views to the proper officials. The tax rate is dependent upon 1) school and local governmental levies [the amount of money a taxing body certifies to be raised from the property tax], 2) the statutory limits and 3) voter's response to referenda issues.Back to Top
Our database cannot accommodate the size of most commercial, industrial, and multi-family buildings. Therefore, sketches are on record in hardcopy and not electronic format. If you need a sketch, please contact us and we will assist you. We can fax or email you a sketch.
Commercial properties include multi-family dwellings that are at least 4 units or more, and any commercial or industrial buildings. Agricultural is listed under residential.
Each habitable structure is listed as a separate record or card. For example, if a property contains two houses that property will have two cards.
You can call or visit the Office of the Assessor. We can print, email, or fax you a copy.
Value information is subject to change, either caused by changes in a property's description or by the action of the Board of Review. To avoid confusion we do not display it. For the latest known assessment data, you can visit www.wingis.org. When viewing the Property Details page, click Assessment Details.
Commercial & industrial property is currently being re-listed. When all of it is deemed accurate it will be shown.
Our database does not allow for site area aerials. You can visit www.wingis.org and view the site area by clicking the binoculars in your search results page.
The Rockford Township Assessor's Office receives this information from Winnebago County. The ultimate sources are recorded documents such as deeds, plats, surveys and so on.
For structures built in the past 50 years or so the source is the building permit. Generally, the Year Built for older houses is an educated guess.
Our Database system does not have the capability to store years before 1900. Therefore "1900" means 1900 or before.
In both cases the amount of finish space must be sufficient to qualify as useful space that contributes to value and is shown in square feet. The difference between the two is that Finished Basement Living Area is found in basements that are partially or fully exposed.
This classification is used when a building has some brick veneer, but not enough to qualify to list the Exterior Walls as Brick and Frame. Shown in square feet, it typically used for cases of brick trim, half wall brick fronts, etc.
This is that part of a building that is not habitable due to destruction (fire, storm damage, etc.), demolition or incomplete construction.
Dimensions are rounded to the nearest foot. Therefore, areas may not be absolutely accurate. Use the dimensions and areas shown on this site with caution!
We record only sale month and year.
Three types of sales are possible: 1) land only, 2) improvements only and 3) land with improvements. NOTE: Vacant land will be listed as Land & Bldg if it contains any improvement that generates a value, no matter how small a value that may be.
The sale prices listed are NET amounts after any declared personal property is deducted from the total sale price. We do not keep track of the value of personal property claimed, if any.
Internally, this is how we delineate sales that qualify as good, market sales from those that may not qualify as arms length transactions.
This designator is applied to a sale if more than one property was sold or if the property was not exposed to the open market.
We receive notifications from the City of Rockford, City of Loves Park, and from Winnebago County.
We list the month and year in which each building permit is issued. If an inspection reveals that an improvement was added without a building permit it is designated by listing the month as "00".
This is the figure, often rounded, that the permit applicant estimated as the cost of the work being done. Our best advice is to use this figure with a good deal of caution. The Purpose column shows the work being done in summary form.
Every effort is made to draw the Sketch to scale. Small or crowded dimensions are not shown in the interest of legibility.
It is always at the bottom, as if facing it from the street.
For descriptive purposes each building has a main section, labeled as "A" in the attachments table. The main section (A) includes the total above grade living area plus, if applicable, finished attic space & finished basement living area. Any attached structure(s) such as more living space, garage, porch, deck, etc. are additions and each has its own value.
Detached buildings such as sheds, garages and agricultural buildings. In addition detached decks, patios and porches plus such things as swimming pools and tennis courts. Driveways are listed, but not valued (the items with no size and a year built of 1900).
Sidewalks, fences, landscaping plus any improvement not permanently affixed to the land are not listed.
Close to two dozen attributes are considered when valuing property. Attributes include, but are not limited to, square footage, number of stories, type of construction, foundation type, heating type, plumbing fixtures, garage style, central air, finished space, stoops/decks/patios, porches, quality or grade of construction, masonry trim, fireplaces, cost factors, neighborhood or design factors, condition of property, and/or depreciation. When considering your own comparables to support a complaint, you are best advised to consider the same attributes as well.
Your township assessor may have revalued your property or, as required by law, an equalization factor was applied by the Winnebago County Supervisor of Assessments to adjust the level of assessments in each township to 33 1/3%. For specific reasons, please contact our office at (815) 965-0300 for an explanation.
Fair Market Value (FMV) is what an informed buyer would pay to a seller for a piece property on the open market. Often times, due to assessments being compared on a mass appraisal basis, our FMV may be lower, higher, or right at the true FMV. If you feel that your assessment in incorrect, please call our office at (815) 965-0300 to discuss your assessment.
Assessed Value is considered to be 1/3 of the Fair Market Value.
It can. But only at the Board of Review level and only if it is an arm’s length sale. The Office of the Assessor statutorily does not have the authority to reduce assessments based on sales price. However, if the Office of the Assessor determines just cause, it can lower a condition, design or neighborhood factor. If that does not satisfy the owner, it is best to file a complaint with the Board of Review.
The Supervisor of Assessments or the Board of Review applies the Township Equalization Factor. Each of the 14 townships in Winnebago County can have a different equalization factor. Its purpose is to equalize all townships within a county to the same level of assessments. The Illinois Department of Revenue applies the County Multiplier to equalize all counties in the state to the same level of assessments. The level of assessments trying to be attained is 1/3 of fair market value at the township, county, and state levels.
A sale is considered valid when the transaction is an arm’s length transaction and conveyance is via a warranty deed. This includes all parties being knowledgeable of the market, making informed decisions without undue influence, having the property exposed to the open market, and/or not involving a financial or governmental agency as the principal buyer or seller.
A sale is considered invalid if it meets one or many of the following: it involves a financial or government agency; multiple parcels are included in a sale price; when one parcel is being divided into multiple parcels; parties are related individuals or corporations; the sale is mandated by the court; when only a portion of the parcel or interest is transferred; when parcels are traded; if a deed other than a warranty deed is used to convey the parcel(s); or if the property was not exposed to the open market.
You may find your assessment history by calling our office or visiting WinGIS, (click Assessment Details, then Assessment History).
WinGIS provides current FEMA Flood Data to the public. To view this data, search your parcel, click its PIN on the search results page, click Flood Zone, Voting District, Zoning and More located just under the Available Parcel Sales History, then click the Flood Zones link. In bold red letters, it will read whether you are in or out of a FEMA flood zone. For accuracy, you are advised to verify all data.
Land is a supply that is naturally fixed and considered indestructible. Therefore, its value generally does not decrease. However, improvements or buildings can frequently change in value based on condition, design, and other attributes or events.
An assessment change notice is a notice mailed by the Supervisor of Assessments office to notify an owner that the Assessor has changed the property’s value. It is important to note that these notices are published and the period to file a complaint is 30 days from publication. Please remember, your tax bills will be based on the assessed value on the notice.Back to Top
