Filing Illinois State W-2s Electronically Through QuickBooks Desktop
QuickBooks Desktop users preparing Illinois state W-2 filings can use the built-in e-filing worksheet to verify and submit wage and withholding data for each employee.
QuickBooks Desktop includes a dedicated worksheet for electronically reporting Illinois state W-2 information, but the prefilled data still requires a careful review pass before submission. The worksheet pulls wage and tax details directly from the company file, yet several fields depend on manual confirmation — and skipping that review can result in inaccurate filings with the Illinois Department of Revenue.
What the Worksheet Prefills
When you open the Illinois W-2 e-filing worksheet, QuickBooks automatically populates the Employer section, the Employee section, and boxes 15 through 17 with data already stored in the company file. For QuickBooks 2011 and later versions, federal data for boxes 1 through 13 is also prefilled automatically. Users running QuickBooks 2010 or earlier must manually copy the figures from their federal W-2s into those boxes.
Boxes 8, 14, and 18 through 20 do not apply to Illinois filers and should be left as-is. Every prefilled value should be cross-checked against the federal W-2s you have already filed to confirm the numbers match.
Third-Party Sick Pay
The worksheet allows you to enter applicable third-party sick pay and any associated taxes withheld. If an employee received third-party sick pay during the year, that amount is added to their total wages and included in the data transmitted to Illinois. Without this manual entry, the state filing would underreport that employee’s compensation.
Step-by-Step: Completing the Worksheet
The worksheet walks through a structured interview process. Each step narrows down the filing details for your company.
Step 1 — Select Your Kind of Payer
Choose the single payer category that applies to your business. QuickBooks defaults to 941, which covers most employers. The available options are:
- 941 — the most common category, covering standard quarterly filers
- 943 — agricultural employers
- 944 — annual filers
- Military
- Household employer
- Medicare government employer
- CT-1 (Railroad employer) — not supported by QuickBooks for this filing
If you are unsure which category applies, refer to the IRS instructions for Forms W-2 and W-3.
Step 2 — Select Your Kind of Employer
This step, introduced for the 2011 filing year, asks you to identify your employer type. QuickBooks defaults to None apply, which is correct for the majority of businesses. The options are:
- None apply — most common
- State/local non-501c — state or local government entities that are not tax-exempt under section 501(c)
- 501c non-government — nongovernmental organizations with tax-exempt status under section 501(c)
- State/local 501c — government entities that also hold 501(c) tax-exempt status
- Federal government — federal entities or instrumentalities
Step 3 — Answer the Special Situations Question
The worksheet asks whether any special situations listed on the interview screen apply to your employees. Select Yes if any of the listed situations apply, or No if none do. The specific situations presented depend on your earlier selections, so review each item carefully before proceeding.
Verifying Employee Data
After completing the interview steps, review each employee’s wage and tax information line by line. Confirm that state wages and Illinois tax withholding figures are accurate. Any discrepancy between the worksheet and your federal filing should be resolved before you submit — once the data is transmitted, corrections require a separate amended filing process.
Getting Help Within the Worksheet
The worksheet window includes a Help button that opens context-specific guidance for navigating the form and troubleshooting issues you encounter while working through it. If a particular field or prompt is unclear, that built-in help is the first resource to check.
A Note on Older Versions
Users on QuickBooks 2010 or earlier face additional manual work because federal box data is not prefilled. If you are still running an older version of QuickBooks Desktop and encounter issues with the worksheet or filing process, the extra manual entry step is the most likely source of errors. Double-check every transferred figure against the federal return before submitting to Illinois.
