Why You Need a Quarterly Contribution and Wage Report
The Quarterly Contribution and Wage Report in Aurora, Illinois, is mandated by the Illinois Unemployment Insurance Act (820 ILCS 405/). This is a state-level requirement enforced by the Illinois Department of Employment Security (IDES), which administers the unemployment insurance program. As a restaurant owner in Aurora, you are required to register as an employer with IDES and file these reports to fulfill your obligations under the Act, specifically Sections 1400 through 1500, which detail contribution rates, wage reporting, and payment schedules.
Failure to file this report accurately and on time triggers a series of escalating penalties and practical consequences. This is not just a paperwork formality; it directly affects your business's financial standing and legal compliance. Key consequences include:
- Monetary penalties: IDES assesses penalty fees for late filing or payment. These are separate from the owed contributions and interest.
- Interest on unpaid contributions: Unpaid unemployment insurance contributions accrue interest from the due date until paid in full.
- Fraud penalties: Willful misrepresentation, such as underreporting wages, can result in severe civil and criminal penalties.
- Cease-and-desist risk: While rare for reporting lapses, persistent non-compliance can lead to legal action, liens against business assets, and suspension of business operations.
- Insurance and lease implications: Outstanding state tax liens can invalidate surety bonds, complicate insurance renewals, and breach financial covenants in commercial leases, potentially jeopardizing your location.
Legal code: State unemployment insurance act, employer registration requirements
Recent update: In 2026, IDES continues to emphasize its online portal, MyTax Illinois, as the primary and mandated method for filing the Quarterly Contribution and Wage Report for all employers, including those in Aurora.

71 of 85 auto-filledLegal Business Name
textEnter the exact, full legal business name as it is registered with the Illinois Secretary of State and appears on your IRS paperwork.
COMMON MISTAKE: Using a DBA or trade name instead of the registered legal entity name, which will cause a mismatch with state records.
Street Address
textEnter the official street address for the business, including the building number and street name.
COMMON MISTAKE: Leaving the field blank or entering a PO Box here—this should be the physical street address for correspondence.
City, State, and ZIP Code
textEnter the city, state abbreviation (IL), and ZIP+4 code that correspond to the street address above.
COMMON MISTAKE: Entering the wrong ZIP code or forgetting the state abbreviation can cause mail delays and processing issues.
Additional Employer Information
textEnter any additional reporting location or department information as required by your internal payroll system.
COMMON MISTAKE: Entering information that belongs in the 'Employer Name' or 'Address' fields, which clutters the form and can cause confusion.
Line 6B: Late Filing Penalty
textIf filing late, enter the calculated late-filing penalty amount as specified by the Illinois Department of Employment Security (IDES).
COMMON MISTAKE: Entering the penalty amount in the 'Interest' field, or leaving it blank when a penalty is actually due, which leads to an underpayment notice.
Line 6A: Interest on Late Payment
textIf your contribution payment is late, enter the calculated interest on the overdue amount as determined by IDES.
COMMON MISTAKE: Confusing this with the penalty field or entering an incorrect interest amount that doesn't match IDES calculations, triggering a correction notice.
Federal Employer Identification Number (9 digits)
textEnter your 9-digit Federal Employer Identification Number (FEIN) issued by the IRS, without dashes or spaces.
COMMON MISTAKE: Entering a Social Security Number, transposing digits, or adding hyphens, which causes an immediate match failure with state and federal databases.
Change in Status - No IL Workers

Top 5 Quarterly Contribution and Wage Report Mistakes
1. Reporting Total Wages Instead of Taxable Wages
Entering the full gross payroll amount for the quarter instead of the amount subject to Aurora's employer's occupation tax (EOT). This triggers a discrepancy notice, adds 2-3 weeks for reconciliation, and can lead to an incorrect tax bill. To avoid, calculate taxable wages by subtracting any non-taxable compensation (like certain fringe benefits) as defined by Aurora code. Example: If you paid $50,000 in total wages but $2,000 was for non-taxable health insurance premiums, your reportable wage total should be $48,000.
2. Incorrect Quarter or Year Selection
Selecting Q1 2026 on the form when reporting for Q4 2025, or entering the wrong report year entirely. This causes the payment to be misapplied, leading to penalties for a late Q4 filing and a confusing credit on your Q1 account. Always double-check the report period dropdowns and the year field against your payroll records before submitting. This simple error typically adds 3-4 weeks to resolve with the City Finance Department.
3. Mismatched EIN or Business Account Number
Using a federal Employer Identification Number (EIN) that doesn't match the one on file with the City of Aurora, or entering an incorrect local business license number. This prevents the system from properly crediting your payment, flagging it as 'unapplied' and risking a late-filing penalty. Verify the exact EIN and Aurora business account number from your prior quarter's filing confirmation or your city business license certificate.

Aurora Quarterly Contribution and Wage Report Timeline
Gather Quarter-End Payroll Records (Step 1)
Compile all payroll documents for the reporting quarter (January–March, April–June, July–September, or October–December). You need total gross wages paid to all employees, the total number of covered workers for each month, and a detailed breakdown by employee showing wages and hours worked. This data is typically pulled directly from your payroll software or service. Inaccurate wage totals are the most common cause of filing errors and subsequent penalties from the city.
Complete the Aurora Form R-1 (Step 2)
Fill out the City of Aurora's official Form R-1, 'Quarterly Employer's Return of Contributions and Wage Report.' You must enter your 7-digit Aurora Business Tax (ABT) number, your Federal Employer Identification Number (FEIN), and the precise quarterly totals from your payroll records. The form requires separate reporting for each month within the quarter. Most filers complete the 20+ data fields on the R-1 in under 30 minutes if their payroll summary is accurate and organized.
Submit Report & Payment Online (Step 3)
File the completed Form R-1 and remit any owed unemployment contributions via the City of Aurora's online payment portal. You must submit by the deadline: the last day of the month following the end of the quarter (e.g., April 30 for Q1). The portal accepts ACH payments and electronic forms. Missing the strict deadline triggers automatic penalties and interest, even if no tax is due for the quarter.

See All RequirementsProcessing timelines for payroll reports are not publicly standardized and vary based on the state agency's caseload and submission volume. Contact the Illinois Department of Employment Security (IDES) directly for the most current estimate, as processing is tied to your tax account and reporting accuracy. Submitting complete reports on time avoids penalties, unlike missing your City Business License/Registration renewal, which has a fixed annual deadline.
There are $0–$0 in government filing fees to submit the quarterly report itself, per the Illinois Department of Employment Security (IDES). You must, however, pay your calculated unemployment insurance contributions and any wages subject to withholding. Not legal advice — verify payment amounts with IDES.
No, the report is tied to your state employer account, not a physical address. If you move your business within Aurora or Illinois, you must update your business address with IDES using their specific change form. This is distinct from transferring a Building Permit or Certificate of Occupancy, which are location-specific approvals from the City of Aurora.
You do not 'renew' this report; you are required to file it four times per year, by the last day of the month following each calendar quarter (April 30, July 31, October 31, January 31). Failure to file by these deadlines triggers automatic penalties from IDES. Your underlying employer account remains active unless you formally close it with the state.
There is typically no physical inspection for filing the quarterly wage report. IDES conducts audits based on the data you submit, which may involve a records review. Ensuring your reported wages match your payroll records is critical, as discrepancies can trigger an audit, similar to issues that might arise from not having proper Application for Employer Identification Number documentation.
