Appeal in four easy steps

Your home is overassessed

Since property tax assessments are done en masse, the county assessor often gets it wrong. That's why everyone should appeal.

Step 1

Look up your property here

All we need is your address. Our algorithm analyzes every single property in your neighborhood to estimate how much you can save.

Step 2

We manage your paperwork

We'll assemble the appeal forms, keep track of the deadlines, and submit your paperwork and evidence to the county assessor.

Step 3

Save money!

You'll be notified within 6-8 weeks of the county's decision. The majority of appeals win, and an assessment reduction can potentially lower your tax bill by thousands.

Step 4

  • How much does it cost?

    We offer two pricing options to suit your needs. You can either pay a risk-free $149 flat fee up front, which we refund if the appeal doesn't win, or instead elect to pay 30% of your savings when the appeal is successful. Either way, it's a 100% risk-free proposition. If you don't save, we don't get paid.

  • How much can I save?

    Our research shows that the majority of people that appeal successfully reduce their property tax bill. Our success rate is 37% better than the Cook County average. A successful appeal results in an average savings of $650.

  • Can my assessment increase as a result of filing an appeal?

    In almost all counties, your assessment will never increase because you filed an appeal. In some, while it is technically allowed, it is extremely rare—less than 0.1% of appeals result in an increase.

  • Is TaxProper a law firm?

    No, we are not a law firm and we do not provide legal advice. We are a technology company working to make property tax appeals easy and affordable for everyone.

  • How quickly will my appeal be processed?

    We can promise that you can get your appeal filed in 5 minutes or less through TaxProper. The county typically will take several weeks to months to process the appeal.

  • My tax bill is due soon and my appeal isn't resolved yet. Should I still pay or do I wait until I get my assessment results?

    TaxProper always recommends paying your property tax bill on time. If your bill is not paid on time, you risk facing delinquency fees. If your appeal is deemed successful and your tax bill is lowered but you've already paid, your county's assessor's office and tax collector will coordinate a refund for the amount you have overpaid.
