Schedule ICR reduces your Illinois income tax by claiming specific nonrefundable credits that flow to Form IL-1040. For 2026, the focus is on three credits: the Property Tax Credit, the K-12 Education Expense Credit, and the Volunteer Emergency Worker Credit. These credits do not increase your refund beyond payments—they lower tax after it is computed on IL-1040.
Who Should Use Schedule ICR
File Schedule ICR if you paid qualifying Illinois residence property tax, incurred eligible K-12 education expenses for a dependent, or served as a qualifying volunteer emergency worker. Most filers complete ICR alongside Schedule M (for additions/subtractions) and, where applicable, Schedule CR (credit for tax paid to other states).
Eligibility + Income Limits (AGI)
Two ICR credits are subject to income limits: the property tax credit and K-12 education expense credit are unavailable when AGI exceeds $0 (married filing jointly) or $0 (all other filing statuses). The volunteer emergency worker credit generally is not AGI-limited. Always align your filing status with your IL-1040 selection and ensure Schedule ICR totals reconcile on IL-1040.
Credit Definitions
- Property Tax Credit: Tax you paid on your principal Illinois residence (you owned and occupied it during the tax year). Not for rentals/vacation homes. Keep county bill and proof of payment.
- K-12 Education Expense Credit: Qualifying expenses for an eligible student (tuition, mandatory fees, certain instructional costs). Keep receipts; ensure the student is your dependent on IL-1040.
- Volunteer Emergency Worker Credit: For qualifying service (e.g., fire/EMS/search & rescue as defined by current rules). Retain your eligibility certificate or equivalent proof.

Scenarios
Property Tax + K-12 within AGI limits: A married couple (MFJ) with AGI below $0 pays $4,000 in primary-residence property tax and $1,200 in eligible school expenses. They enter both on ICR. The combined amount reduces tax on IL-1040 (subject to each credit’s specific cap/percentage as implemented in the calculator).
Above AGI limit: A single filer with AGI above $0 cannot claim the property tax or K-12 credits but may still claim the volunteer emergency worker credit if eligible.
Partial-year move: If you moved mid-year but owned and occupied an Illinois home while paying tax on it, the property tax portion for the period you qualified can be claimed; education expenses follow the student’s enrollment and your dependency claim. Cross-check with Schedule NR if you were part-year resident.
Documentation Tips
- Property tax: Keep the bill showing parcel ID, address, and amount paid; retain bank/treasurer proof of payment.
- K-12 expenses: Keep itemized receipts and school statements; match the student to your dependent list on IL-1040.
- Volunteer credit: Maintain service records/certification for the year; ensure your role meets current eligibility.

Filing Flow + Related Forms
Enter each ICR line amount, confirm AGI thresholds, then carry the Schedule ICR total to the credit line on IL-1040. If you also have additions/subtractions, complete Schedule M. Multi-state earners should review Schedule CR. Families claiming dependents often pair ICR with Schedule IL-E/EITC and may need depreciation adjustments via Form IL-4562 or credit recapture via Schedule 1299-C.
Accuracy checklist: confirm AGI vs. limits, verify your filing status, attach proof for each claimed amount, and ensure ICR totals reconcile to IL-1040. This prevents refund delays and amended returns.

Frequently Asked Questions
Do I need to file IL-1040-X if the IRS changes my income?
Yes. If the IRS adjusts your federal return and it affects Illinois tax, you must file IL-1040-X within 120 days of receiving the federal notice.
Are donations made through Schedule G-L tax-deductible?
Yes. Your Schedule G-L donations are eligible for a federal charitable deduction if you itemize on your federal Form 1040 Schedule A. Keep a copy of the filed schedule and any Lottery confirmation of your gift. The contribution will increase your Illinois payment or reduce your refund, but may lower your federal taxable income in the following year.
Changing jobs mid-year in IL
Update income/withholding and frequency; brackets are flat but credits/exemptions still matter.
Who must file Schedule FD?
You must file Schedule FD if you are a former Illinois resident who receives income (such as installment sale gains or deferred bonuses) sourced from Illinois that became taxable for federal purposes during 2026.
What documentation must accompany Schedule 1299-DA?
Attach copies of the other states’ filed tax returns, W-2s, or K-1s showing withholding and payments. Failure to attach proof can lead to denial of the credit. For convenience, you can track and upload copies directly through the MyTax Illinois portal.
