What do we do?

taxProper helps homeowners save money on their property taxes. We do this by accurately valuing real estate and filing an appeal when your home is overassessed. You can get an appeal filed in two minutes or less with taxProper, and be assured that it is accompanied by the best possible evidence. We currently serve Cook County, IL.

Appealing in four easy steps

Your home is overassessed

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

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.

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.

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.

Keep your savings in your pocket

Law firms can take up to 50% of your tax savings, which often ends up costing homeowners several hundred dollars. We offer a simple, flat fee to keep the savings where they belong: in your own pocket.


taxProper charges a flat $79 refundable, risk-free appeal fee.


You keep 100% of the tax savings.


If your appeal doesn't win, we immediately refund you in whole and you pay $0.
