In tax year 2024 the Cook County Board of Review issued 490,231 decisions on residential property. 294,585 of them, or 60.1%, were "No Change." No change was the most common residential result in every tax year from 2018 through 2025.
So the question every appeal service has to answer is not rare: what happens to your money when the Board says no? Censum's answer is a credit toward next year, not a refund. Here is how it works, what it excludes, and who it fits.
Quick Answer
If you buy a paid Censum appeal packet, file it with the Board of Review within the window, and the Board grants no reduction, your packet fee is credited toward next year's packet for the same property. The credit cannot be transferred and expires 24 months after it is issued. The Contingent Plan and the reduced-price screen do not include it. For scale: the Board gave no change on 60.1% of residential decisions in tax year 2024.
No change is the most common result
Cook County residential Board of Review decisions with no change, by tax year:
| Tax year | Residential decisions | No change | Share |
|---|---|---|---|
| 2019 | 382,266 | 240,240 | 62.8% |
| 2020 | 299,936 | 221,452 | 73.8% |
| 2021 | 432,787 | 317,806 | 73.4% |
| 2022 | 392,855 | 280,546 | 71.4% |
| 2023 | 330,844 | 217,939 | 65.9% |
| 2024 | 490,231 | 294,585 | 60.1% |
| 2025 | 447,784 | 258,201 | 57.7% |
Homeowners who filed on their own did better as a group, but not by enough to ignore the downside. In tax year 2024, 45.1% of self-filed residential decisions were no change (30,678 of 67,981). For attorney-filed residential decisions it was 62.5%.
What to do with this: whatever service you use, find out in writing what you pay, and what you get back, on a no-change decision. It is not an edge case.
Why self-filers lost
The Board records a reason for every no-change decision. For the 30,678 self-filed residential no-change decisions in tax year 2024:
- 27,879 (90.9%): "Analysis of comparable properties, a recent sale, and/or an update of property characteristics."
- 1,985: the Board's condominium and cooperative analysis.
- 336: failure to comply with Board rules or requests, or to provide evidence supporting a decrease.
Nine in ten self-filed losses were decided on the evidence, not on paperwork. The Board looked at the comparables and was not persuaded. That is the case for a second try with a better file, built on newer sales.
The terms in plain English
Step 1: You buy a paid packet. That registers the property for credit tracking. All paid packet tiers include the credit.
Step 2: You file with the Board of Review. You submit the appeal using the packet Censum provides, inside your township's open window.
Step 3: The Board decides. If the final decision is a $0 reduction in assessed value, your packet fee becomes a credit toward the next year's packet for the same property.
What counts as "no reduction"
The trigger is narrow and checkable: the Cook County Board of Review issues a final decision with no reduction in your assessed value. A decision letter that says "no change" is the document that matters.
The credit does not cover:
- An appeal that was never filed, or was filed after the window closed
- An appeal filed without using the Censum packet
- A different property
- The reduced-price screen, which is a separate, lower-cost option for homes below a 50% historical win rate
- The Contingent Plan, because no fee is paid upfront
Censum does not refund delivered packets. Billing errors and duplicate charges go to support for correction.
Why a credit and not a refund
Board decisions take months. By the time a final no-change decision arrives, the next assessment cycle is often close. A credit lines up with that timing.
The next packet is a different packet. It uses the newest public records, newer comparable sales and the latest township evidence. When nine in ten self-filed losses turn on comparables, newer comparables are the point of a second try.
It keeps the price fixed and low. Censum's view is that refund promises carry a cost that ends up in the price. A credit lets Censum keep the upfront packet at $99 while still protecting the homeowner who keeps checking.
How it compares with other offers
"No savings, no fee." Usually a percentage of your first-year savings, often 25% to 50%, charged only if you win. The downside is protected. The upside is shared, and the share grows with the result.
A refund promise. You get money back after a loss, but the price can build that in. Read whether the refund covers the full fee and what you must do to claim it.
Censum's credit. You pay a fixed fee. If the Board gives nothing, you get another try next year without paying again. You keep 100% of any savings.
Who it fits, and who it doesn't
It fits owners who plan to stay in the home and check their assessment again. For them, a credit is close to a refund, and it comes with a fresh packet.
It does not fit owners who expect to sell before the next window. The credit is tied to the property and is not transferable. If you are selling soon, the Contingent Plan is likely the better choice.
A short example
A homeowner buys the $99 packet in the fall, files with the Board inside the township window, and receives a no-change decision months later. The $99 is credited toward a packet for the same home in the next cycle. If the homeowner does not use it within 24 months of the credit being issued, it expires.

FAQ
Do I get money back if I lose?
No. You get a credit for the same amount toward next year's packet for the same property.
How often does the Board give no change on a home?
Often. In tax year 2024 it gave no change on 60.1% of residential decisions, and 57.7% in 2025. For self-filed residential decisions the 2024 figure was 45.1%.
Can an appeal raise my assessment instead?
It is rare. Of 490,231 residential decisions in tax year 2024, 90 were increases.
Does the credit apply if I missed the deadline?
No. The appeal must be filed within the open window using the packet.
Does an Assessor denial trigger the credit?
The credit is tied to a final Board of Review decision. If the Assessor denies your appeal, the Board stage is usually still ahead. See your property has two appeal windows.
Can I use the credit on another home?
No. It applies only to the same property.
