Illinois payroll
Payroll that keeps you compliant in Illinois
Running payroll in Illinois means more than cutting a check. Employers must withhold Illinois income tax, file and pay through the Illinois Department of Revenue, report and pay unemployment insurance to the Illinois Department of Employment Security, register every new hire, and meet a growing list of state and local employment rules — including higher minimum wages in Chicago and Cook County and the statewide Paid Leave for All Workers Act. Numerawise Solutions handles all of it as a managed service, so your filings are accurate and on time.
We are an Atlanta-based practice serving businesses across the United States, including Illinois, led by an Intuit ProAdvisor (Gold tier). We work in your existing platform — QuickBooks Online Payroll, Gusto, ADP, or Paychex — or set up the right one for your size and the locations you operate in.
What's covered
Full-service Illinois payroll
Illinois income tax withholding
Illinois applies a flat individual income tax rate. We calculate withholding on every pay run and file Form IL-941 with payments scheduled on your IL-501 deposit frequency through MyTax Illinois.
IDES unemployment insurance
We register your account with the Illinois Department of Employment Security, apply your assigned UI rate, and file the quarterly UI-3/40 contribution and wage report.
New-hire reporting
Every new and rehired employee is reported to the Illinois New Hire Directory within the required window, alongside W-4 and IL-W-4 setup.
Direct deposit & pay stubs
Same-day or next-day direct deposit depending on your bank, electronic pay stubs, and a self-service employee portal.
Federal filings & year-end
Federal 941, 940, W-2, and 1099-NEC handled alongside the Illinois returns, with year-end distribution and reconciliation included.

State & local rules
Illinois compliance, handled
Illinois has added several employer obligations in recent years. We track and apply the current rules so you do not have to:
- Illinois income tax withholding, filed on Form IL-941 with IL-501 deposits via MyTax Illinois
- IDES unemployment insurance, including the quarterly UI-3/40 report at your assigned rate
- Chicago and Cook County minimum-wage rates, which are higher than the Illinois state minimum
- Paid Leave for All Workers Act accrual and tracking for eligible employees
- Illinois Secure Choice retirement program facilitation for employers without their own plan
- New-hire reporting to the Illinois New Hire Directory
- Chicago Fair Workweek and paid-leave considerations for covered employers
- Multi-state withholding where employees live or work outside Illinois
Rates, thresholds, and minimum wages change from year to year and by locality. We apply the figures in effect for your pay date and confirm the specifics for your business during onboarding.

Illinois payroll FAQs
What Illinois payroll taxes do employers have to withhold and pay?
Illinois employers withhold Illinois individual income tax (a flat state rate) and pay it to the Illinois Department of Revenue, and they pay state unemployment insurance to the Illinois Department of Employment Security (IDES). These sit on top of federal income tax, Social Security, and Medicare. We calculate, file, and pay each of them on schedule.
How and when do I file Illinois withholding?
Illinois withholding is reported quarterly on Form IL-941, with tax deposited on your assigned IL-501 schedule (semi-weekly or monthly) through MyTax Illinois. We manage both the deposits and the quarterly return so nothing is missed.
Do you handle Illinois unemployment insurance filings?
Yes. We register your IDES account, apply your assigned contribution rate, and file the quarterly UI-3/40 wage and contribution report. New employers are assigned a standard rate until an experience rate is established.
Do you handle Chicago and Cook County minimum wage and ordinances?
Yes. Chicago and Cook County set minimum wages above the Illinois state minimum, and Chicago has additional ordinances such as Fair Workweek and paid leave. We apply the correct local rates and rules for employees who work in those jurisdictions.
What about the Illinois Paid Leave for All Workers Act?
The Act entitles most Illinois employees to earn paid leave. We set up accrual and tracking within your payroll so balances are recorded correctly and you stay compliant.
Do I need to offer a retirement plan under Illinois Secure Choice?
Illinois requires covered employers that do not offer their own qualified retirement plan to facilitate the state's Secure Choice program. We help you set up payroll deductions and remittance if the mandate applies to you.
Can you run payroll if I have employees in Illinois and other states?
Yes. We handle multi-state withholding and unemployment for employees who live or work outside Illinois, including registering in the relevant states and applying reciprocity where it exists.
I received a notice from IDOR or IDES. Can you help?
Yes. Send it to us. We respond to Illinois Department of Revenue and Department of Employment Security correspondence on payroll matters, and most notices are resolved within one cycle once we have the underlying detail.
How much does Illinois payroll service cost?
Pricing starts at $50 per month plus a per-employee fee, scaled to your headcount, the states you operate in, and the deliverables you need. You receive a fixed quote within 24 hours of a free discovery call.
Can you migrate us from our current payroll provider?
Yes. We carry over year-to-date totals, employee records, and Illinois and federal account details, and most migrations happen mid-quarter without a gap in service.
