How to Hire Your First Employee as an IL Sole Proprietor
40 hours of paid leave, mandatory workers comp, and vacation payout rules — what Illinois sole proprietors face from hire number one.
Hiring employees as a sole proprietor in Illinois puts you in a regulatory environment that sits between the extremes of California and Texas. Illinois isn’t as heavily regulated as the coasts, but it has meaningful state-level requirements that go beyond the federal baseline — including the relatively new Paid Leave for All Workers Act, mandatory workers’ compensation from day one, and vacation payout rules that can surprise new employers.
For sole proprietors in Chicago, the suburbs, or downstate, understanding these requirements before your first hire prevents the scramble of retroactive compliance.
Illinois Sole Proprietor Employer Requirements: Key State Laws
Illinois adds several state-specific requirements on top of federal law:
| Requirement | What it means for your business |
|---|---|
| Paid Leave for All Workers Act | Since January 2024, every Illinois employer must provide 40 hours of paid leave per year that employees can use for any reason. No documentation required. No minimum employer size. |
| Workers’ compensation from employee one | No small employer exemption. Mandatory the moment you hire. |
| Mandatory vacation payout | All accrued vacation must be paid at termination. Use-it-or-lose-it policies are prohibited. |
| State income tax withholding | Illinois has a flat 4.95% income tax rate, requiring state payroll tax registration and quarterly filings. |
| One Day Rest in Seven Act | Employees must get 24 consecutive hours of rest per week, plus meal periods for shifts over 7.5 hours. |
| Specific new-hire reporting | 20-day deadline to report all new hires to the Illinois Department of Employment Security. |
Does the Illinois Paid Leave for All Workers Act Apply to Sole Proprietors?
The Paid Leave for All Workers Act is Illinois’s broadest leave mandate and applies to sole proprietors from their first employee:
How Much Paid Leave Must Illinois Employers Provide?
| Rule | Details |
|---|---|
| Accrual | 1 hour of paid leave for every 40 hours worked |
| Annual cap | 40 hours of paid leave per year |
| Usage | Employees can begin using accrued leave after 90 days of employment |
| Any reason | The leave can be used for any purpose — personal, medical, family, religious, or anything else. The employer cannot ask why. |
| No documentation required | The employer cannot require a doctor’s note, death certificate, or any other justification |
| Carryover | Unused leave carries over year to year, but the employer can cap usage at 40 hours per year |
| Frontloading option | Instead of tracking accrual, the employer can grant 40 hours at the start of each year |
How Illinois Sole Proprietors Must Track and Manage Paid Leave
You must track leave accrual from day one. If your employee works 30 hours per week, they earn roughly 0.75 hours of paid leave per week. After 90 days, they can begin using it.
The “any reason” provision is important: you can require reasonable notice (up to 7 days for foreseeable leave), but you cannot deny leave based on the reason or require proof. If the employee says they’re taking paid leave tomorrow, and they have the balance, you approve it.
Set up your time tracking system to automatically calculate leave accrual based on hours worked.
Chicago Paid Leave Rules: 80 Hours for Employers in the City
If your business is in Chicago, the Chicago Paid Leave and Paid Sick and Safe Leave Ordinance provides additional protections beyond the state law. Chicago employers must provide both 40 hours of paid leave (any reason) and 40 hours of paid sick leave — a total of 80 hours. The two types of leave accrue separately and have different rules for carryover and usage. Review the Chicago ordinance carefully if you operate within city limits.
How to Track Chicago’s Two-Bucket Leave System
Chicago requires separate tracking of paid leave (any reason) and paid sick leave:
| Paid leave (any reason) | Paid sick leave | |
|---|---|---|
| Annual accrual | 40 hours (1 hr per 35 hrs worked) | 40 hours (1 hr per 35 hrs worked) |
| Carryover | Up to 16 hours | Up to 80 hours |
| Payout at termination | Not required | Not required |
| Can employer require documentation? | No | Only after 3+ consecutive days |
If you use a single PTO bucket instead of separating the two, you risk the entire balance being treated as vacation — which Illinois requires you to pay out at termination.
Does a Sole Proprietor Need Workers Comp in Illinois?
Illinois requires workers’ compensation insurance for every employer with one or more employees:
| Requirement | Details |
|---|---|
| No exemption for small employers | One employee triggers the requirement |
| Sole proprietor coverage | Generally not required to carry personal coverage but can elect it |
| Coverage source | Must be obtained through a licensed private insurer or the Illinois assigned risk pool if no private insurer will cover you |
| Criminal penalties | Up to $500 per day for operating without coverage, plus personal liability for any injuries |
How Much Does Workers Comp Cost in Illinois?
Workers’ comp premiums in Illinois vary by industry classification:
| Industry type | Approximate rate per $100 of payroll |
|---|---|
| Office/clerical | $0.20–$0.50 |
| Restaurant/food service | $1.50–$3.00 |
| Retail | $0.50–$1.50 |
| Construction | $5.00–$15.00+ |
| Landscaping | $4.00–$8.00 |
For a sole proprietor with one employee earning $35,000/year in a restaurant, workers’ comp might cost $525–$1,050/year. It’s a real cost, but it’s required.
Illinois Sole Proprietor Payroll Tax Requirements
Illinois’s flat income tax rate simplifies withholding calculations, but you still need to register and file:
What Payroll Taxes Does an Illinois Sole Proprietor Withhold?
| Tax | Employee portion | Employer portion |
|---|---|---|
| Federal income tax | Based on W-4 | — |
| Illinois state income tax | 4.95% (flat rate) | — |
| Social Security | 6.2% | 6.2% |
| Medicare | 1.45% | 1.45% |
| Additional Medicare (>$200K) | 0.9% | — |
| Federal unemployment (FUTA) | — | 0.6% on first $7,000 |
| Illinois unemployment (SUI) | — | Varies by experience rating |
How to Register as an Employer in Illinois
- Federal: Obtain an EIN from the IRS
- Illinois Department of Revenue: Register for state income tax withholding (Form REG-1)
- Illinois Department of Employment Security (IDES): Register for unemployment insurance
- Workers’ compensation: Obtain coverage through a licensed insurer
Illinois uses a flat tax rate (4.95%), so withholding calculation is straightforward: multiply taxable wages by 4.95%. No brackets, no locality variations (though Chicago has some additional considerations for employer taxes).
Illinois One Day Rest in Seven Act: Meal Breaks and Day Off Requirements
The ODRISA applies to sole proprietors with any number of employees:
| Rule | Details |
|---|---|
| 24-hour rest requirement | Required every consecutive seven-day period |
| 20-minute meal period | Required for shifts of 7.5 or more continuous hours (must begin no later than 5 hours after the start of work) |
| Voluntary waiver | Employees can voluntarily waive the rest day with a written request, but the employer cannot require it |
| Penalties | Up to $500–$1,000 per offense (depending on employer size) |
For sole proprietors running a small operation with limited staff, scheduling around the rest day requirement is important. You cannot simply have your one employee work 7 days every week — they must have at least one full day off.
Use your scheduling system to enforce this automatically.
Does Illinois Require Vacation Payout at Termination?
Under the Illinois Wage Payment and Collection Act (820 ILCS 115/5):
- All accrued, unused vacation must be paid out at termination
- Use-it-or-lose-it vacation policies are prohibited in Illinois
- The payout is calculated at the employee’s final regular rate
- This applies regardless of whether the employee quits or is terminated
Is Paid Leave Under the Illinois PLAWA Subject to Payout at Termination?
The mandatory 40 hours of paid leave under the Paid Leave for All Workers Act does not automatically require payout at termination — unless the employer structures the leave as vacation or PTO. If you keep paid leave separate from vacation (and label it as such), the payout obligation may not apply to the paid leave balance.
Consult with an employment attorney on how to structure your leave policy to manage payout exposure.
Illinois New-Hire Reporting Requirements for Sole Proprietors
Illinois requires every new hire and rehire to be reported to IDES within 20 days:
What Information Do You Report for a New Hire in Illinois?
- Employee: name, address, Social Security number, date of hire
- Employer: name, address, federal EIN
How to File a New-Hire Report in Illinois
- Online: Through the Illinois New Hire Reporting system
- Fax or mail: Using Form IL-W-4 or a substitute format containing all required fields
This is a federal requirement (under the Personal Responsibility and Work Opportunity Reconciliation Act), but Illinois administers it through IDES. The data is used for child support enforcement and fraud detection.

Illinois costs are higher than Texas and Florida due to workers’ comp from day one, state income tax administration, and mandatory paid leave. But they’re generally lower than California and New York.
Sole proprietor rules vary by state. See our guides for California, Florida, New York, and Texas, or read the complete sole proprietorship guide.

Frequently Asked Questions
Should Illinois sole proprietors form an LLC?
Strongly recommended. Illinois sole proprietors have no personal liability protection. An LLC separates business liabilities from personal assets, which is critical once you have employees and face potential workers’ comp claims, wage disputes, and general liability exposure. Illinois LLC formation costs $150 (filing fee). Given the state’s active enforcement environment, the protection is worth the cost.
What if my Illinois sole proprietorship is in Chicago — are there extra requirements?
Yes. Chicago employers must provide 40 hours of paid leave (any reason) plus 40 hours of paid sick leave — 80 hours total. The Chicago Paid Leave and Paid Sick and Safe Leave Ordinance has different accrual, carryover, and usage rules than the state law. Chicago also has a higher minimum wage than the state level. Review the Chicago Business Affairs and Consumer Protection website for current requirements.
