Property tax payments arrived months late for a whole bunch of thousands of Cook County householders final 12 months, inflicting headaches and confusion for property homeowners and the native governments they fund.
Five months later, thousands are still waiting for payments and tens of thousands are waiting for refunds, the newest growth within the know-how improve debacle that has roiled the county’s tax system for greater than 4 years with no clear end in sight.
“I don’t know what happened — I just never got the bill,” stated Melvin Brooks, a 72-year-old retired pastor.
Brooks stated he referred to as the Cook County treasurer’s workplace to ask why he by no means realized what he owes on his residence in west suburban Bellwood.
He worries he’ll get a double invoice suddenly, a whopping unplanned value for the house the place his kids and grandchildren now reside, he stated.
“I tried online, but I can’t get through,” Brooks stated. “There’s some kind of glitch or something.”
The “glitch” is definitely dozens of points which have bedeviled county officers and the know-how contractor, Tyler Technologies. As of final week, practically 2,900 second installment payments that had been purported to exit final November had been still unsent — together with the bungalow Brooks has owned since 1982. Another 8,560 first installment payments from this spring had been additionally in limbo till Friday, when 3,897 had been mailed.
That may imply a subset of taxpayers get three property tax payments in speedy succession this 12 months: ones that ought to have been due final December, this April, and the following spherical slated for the late summer season or early fall.
At the identical time, officers say they’re working by means of a backlog of roughly 91,000 tax refunds totaling some $200 million in overpayments that still must be returned.
It’s the newest black eye for the county within the property tax mess that has set off a yearslong round blame sport amongst elected officers over who ought to be held accountable. Tyler’s multimillion-dollar improve of the county’s property tax methods has hit numerous roadblocks and blown a number of deadlines because it kicked off greater than a decade in the past.
When full, it guarantees to streamline operations throughout the county’s property tax workplaces by changing 20 years of knowledge from disparate methods and eventually retire the county’s growing old mainframe computer systems.
In addition to the opposite issues, taxing districts like faculties and libraries have struggled to grasp how a lot property tax income they will depend on.
“We’re doing the best we can with a bad vendor,” stated Cook County Treasurer Maria Pappas, Tyler’s chief critic, including that the corporate’s lack of urgency to repair ongoing points quantities to “technical incompetence and insanity.”
Extra necessities and performance requests are a given with a venture as massive as Cook County’s conversion, a Tyler Technologies spokesperson stated in an electronic mail, including the corporate at all times responded rapidly with fixes.
Pappas is barred from partaking with Tyler officers engaged on the venture after its CEO stated she subjected employees to months of verbal abuse and threats to officers’ reputations. Pappas didn’t dispute utilizing harsh language and stated she was attempting to carry the corporate to process on taxpayers’ behalf. Tyler stated her ongoing criticism has detracted from discovering options when new issues emerge.
In November, 8,560 payments had been excluded when the county mailed out second installment payments for all the county’s greater than 1.8 million parcels. It wasn’t till March {that a} first batch of these, about 4,200 payments, went out. Another 1,000 or so had been mailed at first of April, and slightly below 500 extra had been despatched April 17, per the treasurer’s workplace.
Officials couldn’t estimate the entire quantity of taxes due within the unsent payments. But the greater than 2,800 properties that had not acquired payments as of final week totaled practically $1.14 billion in taxable market worth, in line with the newest figures from the Cook County assessor’s workplace.
Cook County Board President Toni Preckwinkle downplayed the problem, noting at a mid-April media availability that the payments signify a “relatively small fraction” of the county’s tax base. The unresolved ones will “be out as soon as we can get them out.”
No taxpayers might be assessed late charges or penalties in the event that they pay their invoice inside 30 days of receiving it, Pappas stated.
“All remaining PINS are being processed in collaboration with the treasurer’s office,” Tyler’s spokesperson stated in an electronic mail, referring to the property index numbers related to every parcel and property tax invoice.
Records requested by Illinois Answers Project and the Tribune famous thousands of properties throughout the county with unsent payments — every accompanied with an related “reason” for the problem.
“PAY Message AMT <> MIS” was listed as the explanation for greater than a thousand unsent payments. That refers to a mismatch between the county’s previous mainframe and the portion of the invoice that lists what the property proprietor paid for its first installment, a treasurer’s workplace official stated. Either the quantity was incorrect, or that fee wasn’t factored into the due steadiness for the second installment.
If a full 12 months’s cost was $2,500, for instance, and a house owner paid $1,000 for the primary installment, the invoice below the brand new system may need incorrectly recorded the fee as $980. So the proprietor was — on paper — on the hook for $1,520 as a substitute of the correct remaining quantity of $1,500.
About one other 800 faulty payments had been blamed on “1597 Missed Payments from Logan email on 11/3,” referring to a database administrator within the treasurer’s workplace. That defect entails funds that weren’t correctly factored into ultimate calculations throughout a system blackout that occurred whereas switching to the brand new Tyler platform, officers stated. Nearly 300 payments merely listed the explanation for the error as “unknown.”
“Those notations amount to identifying possible explanations for a defect and a possible pathway to resolution,” treasurer’s workplace spokesman Michael Puccinelli stated in an electronic mail. “We say ‘possible’ because in a proprietary system it’s impossible for CCTO employees to know exactly which proposed solutions will work to eliminate defects in Tyler’s system.”
The listing of excellent payments supplied on April 14 held Tyler chargeable for about 2,700 of them, with the treasurer’s workplace on the hook for about 600.
Affected properties seem scattered throughout the county and by kind of parcel. They included greater than 2,600 residential buildings, 67 condominium buildings and 380 industrial properties. Just over half had been situated in Chicago, with the remainder unfold throughout 121 suburbs.
Sheila Sales, 82, has been calling the treasurer’s workplace each few weeks since final fall to ask when she’ll obtain her invoice.
“I spend an hour on the phone, and then they just tell me there’s something wrong with the computer and they don’t know what’s going on,” stated Sales, who stated she by no means encountered an identical problem within the 40-plus years she’s owned her residence in Chicago’s Washington Heights neighborhood.
“I need my bill,” Sales stated. “I don’t want them to give me a big 2- or 3-year bill where I can’t hardly pay for it.”
South and West Side householders are already reeling from sharply greater property fees when final 12 months’s spherical of payments got here out.
Brooks is equally frightened for the safety of his children and grandkids in his Bellwood residence. The space has been experiencing gentrification pressures, he stated.
“If anything were to happen, it would fall on me,” Brooks stated. “I would be concerned about it for anybody who this shoe is fitting … if you can’t pay it, your house will go on the auction block.”
Taxing our bodies out of the loop on revenues
Meanwhile, smaller taxing our bodies stung by late property tax distributions after fall payments had been paid are still at midnight about how a lot cash they need to anticipate, when it’d drop and the right way to account for it.
Su Reynders, govt director of the Mount Prospect Public Library, informed her board earlier this month that the library acquired $4.6 million from the 2024 tax 12 months. Unfortunately, it landed in the course of the library’s 2026 fiscal 12 months and was still about $670,000 in need of what they anticipated.
Trust within the county is low after months of complaints about communications and explanations for delays. Some districts had been overpaid or underpaid final 12 months, an issue that wasn’t obvious to county officers till the Tribune requested about it.
The irregular circulation of money will distort their monetary experiences and will deepen distrust that the county has satisfactory guardrails to correctly account for the place taxpayers’ cash is ending up.

Reynders and Amy Franco from the Hillside Public Library have been surveying different libraries in latest months and realized a number of are still waiting for 2024 tax 12 months distributions. The 16 districts Franco just lately surveyed estimate they’re still lacking a mixed $4.2 million from the 2024 tax 12 months.
While districts obtain emails when new cash is deposited, it’s tough for these leaders to substantiate how a lot they’re still owed as a result of the county’s extranet for all of its taxing companies just isn’t working, both. The extranet helps leaders observe how a lot property tax income has been collected, which tax 12 months the cash comes from and which sub-funds — for issues like constructing upkeep, employees’ compensation, paying again bonds, pensions or insurance coverage — these funds belong to.
A treasurer’s workplace official stated earlier this month their precedence was getting cash out the door earlier than making the extranet totally purposeful and that they “continue to work through defects with that distribution data.”
Tyler’s spokesperson stated the sub-fund breakout was a latest request and was a brand new requirement, “not an issue with the software. We responded quickly to this request and have provided the information to them for validation.”
One of the issues, the treasurer’s workplace stated, is that Tyler can not say how a lot cash ought to be distributed to every sub-fund. Without full accounting, required monetary statements, annual audits, funds monitoring and forecasting are thrown off and libraries threat spending cash that’s purported to be devoted to pensions on constructing upkeep, Franco stated.
For Reynders, that excellent $670,000 is vital to creating the mathematics work on an ongoing renovation that can drain the library’s capital reserves. She stated it’s been practically 21 years since her library was renovated. “I’ve been careful and fiscally responsible planning for this, but if the money doesn’t come, then what?”
“My No. 1 question right now is, where is the remainder of the tax year ’24 payments? Is it sitting in an account and they’re trying to figure out how to distribute it? Or is that money gone and they don’t know how to rectify? Does the money exist?” Reynders stated. “I will not let this go. I am absolutely committed to seeing that $670,000 accounted for.”
“There’s constant audits in here,” Pappas stated. “There’s no skimming in here.”
Preckwinkle has additionally pledged that this 12 months’s usually scheduled audit of county funds will embrace a give attention to data know-how.
‘Back and forth’ on refunds
Meanwhile, tens of thousands are waiting for the sluggish trickle of refunds to make their means into the mail.
The treasurer’s workplace has not been capable of problem bulk refunds for near a 12 months “due to the large number of underlying data issues that require them to check each refund individually before issuing,” in line with the county’s property tax tracker.
“You get a batch of 300 refunds, and 60% of them are wrong, so they have to go back,” Pappas stated in an interview Thursday. “So it goes back and forth and back and forth.”
Duplicate and overpayment refunds must be cut up into the unique tax, the penalty calculation, and curiosity. Some of these refunds are attributed to the flawed tax 12 months, too.
The drawback stems from “data details that were not provided to us” earlier than the system blackout, Tyler’s spokesperson stated. The knowledge is now in Pappas’ arms for testing and validation, they stated.
Glenn Guttman, a property tax legal professional whose enterprise runs on receiving a share of profitable property tax enchantment refunds, stated business colleagues thought of taking the treasurer to court docket however finally determined towards it. No matter what a choose dominated, the treasurer’s workplace merely can’t lower the examine.
“We can’t chase anything down. Everything is done from our end, a lot of people are waiting for these refund checks. There’s nothing we can do to implore the treasurer to write a check.”
While he understands there are few whose hearts would bleed for appeals attorneys, he notes behind each stalled refund is an individual or a enterprise who probably wants that cash to get by.
Various county workplaces “always say one or two months,” Guttman stated. “April was the first time we had — in one year — any refund come through from the treasurer’s office.”
