How does my assessment relate to market value?
State of Illinois law requires that all property be assessed at one-third (33.33%) of market value for property tax purposes; thus, to determine what market value your home has been assessed at, simply multiply your assessment by three. For more information, see Understanding Your Assessment.

Will my assessment increase because I recently purchased my home?
Not necessarily. Typically, your assessment will not be increased simply because it has just had a sale. Our concern is always accuracy and uniformity of assessment.
However, keep in mind that a sale above your assessed value may compel us to re-examine your assessment; if we find that the discrepancy is due to error, we may have to adjust the assessment to the level it should have been at in the first place.
Note that a sale that is above your assessment may also indicate a trend or change in an area's market value, possibly requiring us to re-examine all assessments in a neighborhood for correct and equitable levels of assessment.

What can I do if I feel I am being over-assessed?
The first step is to decide whether or not your assessment is out of line with market value. You can investigate this in a number of ways:
  • Drop by the Hampshire Township Assessor's Office and review the assessments records for homes comparable to yours
  • Obtain an appraisal of your home and compare it to your assessment
  • Get an opinion from a realtor (Note: a realtor's opinion should only be used as a guideline when investigating market value)
  • Check our Online Database for assessments of homes you believe are comparable to yours

What will happen to my assessment if I add an addition or amenity to my home?
Any new construction you do on your home that increases its market value must be reflected in your assessment. This can include (but is not limited to) additions, decks, porches, et al. Upon receiving a copy of your construction permit, a member of our staff will flag your property for and inspection for the following year. Since your home is assessed based on its status as of January 1st of each year, our inspections are always performed during the calendar year following the permit date; see Understanding Your Assessment for more information. After inspection, we will add your new construction to your assessment. However, if you own and occupy your home as your principal residence, you will qualify for the Home Improvement Exemption. The HIE exempts you from being taxed on that portion of your assessment that is attributable to your new construction.; the maximum amount that will be exempted is $25,000 and the Home Improvement Exemption expires after four years.

For more information, contact our office or the Kane County Supervisor of Assessments.
