With a new online system, tax appeals for Cook County can now be filed online.

Cook County has just launched a new online system that allows owners of the 1.83 million real estate parcels in the area to appeal their tax bills electronically, an evolution that greatly simplifies the process.

Previously, owners had to submit paper appeals at county offices or approved outreach centers. No online system exists for commercial properties, though, so those forms must still be submitted in-person.

Accessible at cookcountyboardofreview.com, the new system is expected to increase the number of appeals, which stood at 380,000 in 2010. But at least there won’t be any more paper.

“That’s really my goal, to have a completely paperless system,” said Michael Cabonargi, one of the three board commissioners. “We have thousands of file cabinets here and offsite with all the appeals for the last five years.”
