Illinois has the second highest property taxes in the nation. As a homeowner in the Land of Lincoln, you are undoubtedly aware of the burdens of those taxes. But what you may not realize is that there are ways to lower your property tax bills and ensure that you are not overpaying. So how can you reduce your property tax burden? There are two primary methods. The first is available to all homeowners. The second depends on whether you meet certain qualifications under the Illinois tax code. If you do, you can seek tax relief using both methods.

Method #1: Appeal the Taxable Value of Your Home

You may know that the Illinois authorities compute your property tax by multiplying your home's taxable value by the tax rate. The taxable value is essentially the fair market value of your home, taking into account its condition, location, and size.

For example, imagine that the state tax assessor has placed a taxable value of $200,000 on the Samsons' home. If the tax rate is 1%, they will owe $2,000 in property tax.

If you can reduce the taxable value of your home, your property tax bill will be lowered. Imagine that the Samsons decide to appeal the $200,000 taxable value of their home, insisting that the value is actually lower. The appeals board reduces that value to $150,000. Now, the Samsons owe only $1,500 in property tax.

You may check the appraisal value of your home with your county clerk's office. Be sure that it properly describes your home's size, and does not overestimate its condition.

If you believe that the Illinois tax assessor has misjudged the value of your home, or if the taxable value is higher than that of similar homes, you might want to pursue an appeal.

Method #2: Obtain All Tax Breaks to Which You're Entitled

Beyond trying to lower the appraised value of your home in the eyes of the assessor, Illinois also allows for reduced property taxes if you meet certain requirements. The chief statewide programs in Illinois are summarized here. For the law itself, see Illinois's Property Tax Code at 35 ILCS Section 200.

Contact your local tax assessor for complete details on these and other Illinois property tax exemptions, including any required forms you need to complete and the deadline for filing those forms. Contact information for the assessor's office is available from this online list of Illinois assessors.
