Eight exemption errors worth ten minutes of your time
A checklist to run against your tax bill before you consider anything harder.
Eight things to check on your bill. Most take under a minute, and any one of them can be worth more than a successful appeal.
1. No homestead exemption at all
Look for "Owner Occupied" or "General Homestead". If you own and live in the property and it is not there, this is the finding. Worth around $750 a year in Cook County.
2. An exemption that vanished this year
Compare this bill against last year's, line by line. A missing line is a lapsed renewal, an ownership or title change, or an administrative error — all of which are fixable.
3. Turned 65 and never applied
The senior homestead exemption is additional to the general one, has no income test, and requires an application. You qualify if you reach 65 at any point during the tax year, not only by 1 January.
4. Eligible for the freeze and not claiming it
Separate from the senior exemption, income tested, and requires an annual application. Worth little in year one and a great deal after a decade. Missing a renewal resets the frozen base permanently.
5. A disability rating that has changed
Veterans' relief is tiered by service-connected rating, and at 70% or above the property may be fully exempt. A rating increased on review does not update the exemption automatically. Check the tier on your bill against your current rating.
6. A surviving spouse benefit nobody mentioned
Several exemptions can continue for a surviving spouse. This is among the most missed benefits anywhere, because it must be claimed at the worst possible moment and nobody raises it. Ask the assessor's office directly what continues.
7. Improved the property and never got the home improvement exemption
Four years of relief on the added value, running from completion. Check the year after any permitted work whether the increase appeared and whether the exemption was applied.
8. Prior years never claimed
The one people never ask about. If you were entitled and did not receive an exemption, several Illinois counties allow correction for prior years by certificate of error, with a refund of tax overpaid. It is not advertised, it is not governed by the appeal deadline, and it is granted more often than people expect.
Why this list beats an appeal
Every item above is an entitlement rather than an argument. You do not have to persuade anyone, assemble comparables, or beat a 23% success rate. You have to find the form and complete it — and in several cases, recover money you have already paid.
