To start a cleaning business in Illinois, you form a legal entity with the Secretary of State, get a federal Employer Identification Number, register for state taxes, and — if you plan to hire anyone — carry workers’ compensation insurance before that first employee starts. From there, you’ll need the right business insurance, any local permits your city requires, correct worker classification, and OSHA-compliant chemical safety practices. The LLC filing fee is $150, most of the paperwork is handled online, and the sequence below keeps the requirements in the order they actually need to happen.
Pick a Structure and Clear a Name
Most cleaning business owners form a limited liability company. An LLC shields personal assets from business debts without the formal shareholder requirements a corporation carries. Sole proprietorships are simpler, but they offer no liability protection, and that matters in a business where employees enter other people’s homes and offices every day.
Before you file anything, run your name against the Illinois Secretary of State’s database of registered business names.1Illinois.gov. Locate Registered Business Names Your name must be distinguishable from every active entity on file. An LLC name has to include “LLC” or “Limited Liability Company.” The state will reject a filing with a name that’s already in use, so search first.
Appoint a Registered Agent
Every Illinois LLC and corporation must designate a registered agent with a physical Illinois address. The agent receives legal notices and government correspondence for the business. For an LLC, the agent must be an Illinois resident or a business entity authorized to operate in the state.2Illinois General Assembly. Illinois Code 805 ILCS 180/1-35 – Registered Office and Registered Agent Corporations face the same requirement under a parallel statute.3FindLaw. Illinois Code 805 ILCS 5/5.05 – Registered Office and Registered Agent You can serve as your own agent if you have an Illinois address, or hire a commercial service.
File Formation Documents With the Secretary of State
LLCs file Articles of Organization on Form LLC-5.5. It asks for the business name, principal office address, registered agent, a brief purpose statement (janitorial and cleaning services works fine), and whether the LLC is member-managed or manager-managed.4Illinois Secretary of State. Form LLC-5.5 Articles of Organization Corporations file Articles of Incorporation on Form BCA 2.10.5Illinois Secretary of State. Form BCA 2.10 Articles of Incorporation
The LLC filing fee is $150. Corporations pay $150 at minimum plus any applicable franchise tax. Online filings through the business services portal typically process in two to ten business days.6Illinois Secretary of State. Department of Business Services Paper filings go by mail to the Department of Business Services in Springfield. Once approved, the state returns a stamped Acknowledgment of Filing with your file number. Banks, landlords, and licensing offices will ask for it, so keep it somewhere you can find it.
Get an Employer Identification Number
An EIN is your business’s federal tax ID. You need one to open a business bank account, file tax returns, and run payroll.7Internal Revenue Service. Employer Identification Number The online application is free and takes about ten minutes. Provide the entity name, the responsible party’s Social Security number, and the business address. The IRS issues the number immediately on completion of the digital application.8Internal Revenue Service. Get an Employer Identification Number
Register for Illinois and Federal Taxes
Illinois Department of Revenue
File Form REG-1 through the MyTax Illinois portal.9Illinois Department of Revenue. REG-1 Illinois Business Registration Application This sets up your account for withholding state income tax from employee paychecks, and a sales tax account if you need one.
Here’s the detail that trips up new cleaning owners: Illinois does not tax sales of services.10Illinois Department of Revenue. Does Illinois Tax Sales of Service? Your labor charges for cleaning a home or office aren’t subject to sales tax. If you sell tangible products alongside the service — supply kits, air fresheners — sales tax applies to those items. A cleaning business that only provides services and supplies its own materials usually won’t collect sales tax, but you still complete REG-1 for the withholding account.
State Unemployment Insurance
Any business with employees must register with the Illinois Department of Employment Security and contribute to the state unemployment fund.11Illinois General Assembly. Illinois Code 820 ILCS 405 – Unemployment Insurance Act This can be done through the MyTax Illinois portal. New employers generally pay 3.35% of taxable wages. Cleaning businesses fall under NAICS sector 56, which carries a slightly higher entry rate of 3.45% for 2026.12Illinois Department of Employment Security. 2026 State Experience Factor and Employers UI Contribution Rates Contributions are due quarterly.
Federal Unemployment Tax
FUTA charges employers 6.0% on the first $7,000 of each employee’s annual wages. If your state unemployment account is in good standing and Illinois is not a credit reduction state, you receive a 5.4% credit, bringing the effective rate to 0.6%.13Internal Revenue Service. FUTA Credit Reduction FUTA is reported annually on IRS Form 940.
Carry Workers’ Compensation Insurance Before You Hire
Illinois is strict on this. Every employer with at least one employee must carry workers’ compensation insurance. There is no small-business exemption. The coverage pays for medical treatment and lost wages when an employee is injured on the job, and in a cleaning business slips, chemical exposure, and repetitive-motion strain are common.
An employer who knowingly operates without coverage faces fines of up to $500 for every day without insurance, with a minimum penalty of $10,000.14Illinois Workers’ Compensation Commission. Insurance Get a policy in place before your first employee’s first day.
Add the Other Insurance a Cleaning Business Needs
Workers’ comp is legally required. The rest of the coverage below is not required by statute, but operating without it is a gamble most owners can’t absorb.
- General liability insurance covers claims when your work damages a client’s property or someone is hurt because of your operations — a broken vase, a wet floor, chemical damage to a countertop. Policies typically start at $1 million per occurrence, which is also the threshold most commercial clients require before they’ll sign a contract.
- A janitorial bond, also called a surety bond, reimburses clients if an employee steals property while on a job site. It’s a guarantee to your clients rather than insurance for you. Many residential and commercial clients expect it before granting building access.
- Commercial auto insurance is required if you or your employees drive company-owned vehicles to jobs. A personal auto policy won’t cover accidents during business use. If employees drive their own cars for work, look into hired and non-owned auto coverage instead.
Check Local Permits and Business Licenses
Illinois does not issue a statewide cleaning license, but cities and counties often require a general business license before you can operate in their jurisdiction. Requirements and fees vary widely. Chicago runs its own business licensing system with periodic renewals.15City of Chicago. Renewing a Business License Suburban and downstate municipalities each have their own rules.
Before you book a job in any jurisdiction, contact the local clerk’s office or check the municipality’s website. Some areas also enforce home-occupation permits if you run the business from your residence, and zoning may limit where you can park commercial vehicles or store supplies.
Classify and Pay Your Workers Correctly
This is where cleaning businesses run into the most trouble. Bringing on cleaners as independent contractors looks attractive because it avoids payroll taxes and insurance obligations, but the IRS looks at the actual working relationship, not what the contract calls it. Three categories drive the classification:16Internal Revenue Service. Independent Contractor (Self-Employed) or Employee?
- Behavioral control. Do you decide what tasks the worker performs, what hours they work, and what methods they use? That points to employee status.
- Financial control. Do you provide the supplies and equipment, set the pay rate, and reimburse expenses? The more financial control you exercise, the more the worker looks like an employee.
- Relationship type. Is the work ongoing? Is cleaning a core part of your business? A permanent role performing your company’s primary service almost always qualifies as employment.
No single factor is decisive; the IRS weighs them together. Realistically, if you schedule a cleaner’s shifts, hand them your supplies, and send them to job sites you chose, that person is an employee regardless of any independent contractor agreement you both signed. Misclassification triggers back taxes, penalties, and potential liability for unpaid workers’ comp premiums.
Wage and Hour Requirements
Illinois employees must be paid at least $15.00 per hour as of 2026, which applies to employers with four or more workers.17U.S. Department of Labor. State Minimum Wage Laws Federal law requires overtime at one and a half times the regular rate for any hours worked beyond 40 in a single workweek.18eCFR. Title 29 Part 778 – Overtime Compensation You can’t average hours across two weeks to avoid overtime. Each workweek stands on its own, so if you staff evening or weekend shifts, your payroll system needs to track hours accurately by week.
Handle Cleaning Chemicals the Way OSHA Requires
Cleaning companies use hazardous chemicals daily, and OSHA’s Hazard Communication Standard applies to every one of them. If your employees handle any product with a hazard warning on the label, you need a written hazard communication program covering container labeling, safety data sheets, and employee training.19OSHA. Hazard Communication Standard 1910.1200
In practice, that comes down to three things:
- Keep a Safety Data Sheet on file for every hazardous chemical your employees use, and make the sheets accessible during work hours. A binder in the supply closet or a phone app both work, as long as employees can reach the information without leaving the work area.20OSHA. Hazard Communication Standard – Safety Data Sheets
- Train every worker on the hazards of the chemicals they’ll use before they start using them. Training covers how to detect a hazardous release, what protective measures to take, and where the SDS information lives.
- Assess what personal protective equipment each job requires — gloves, eye protection, respirators — and provide it at no cost to employees. Train them on how to use it properly before they’re on a job site.21OSHA. General PPE Requirements 1910.132
Skipping any of this isn’t just a regulatory risk. An employee who mixes bleach and ammonia in a client’s bathroom because nobody trained them on chemical incompatibility is a lawsuit, a workers’ comp claim, and an OSHA citation in one.
Use Written Service Contracts
A handshake agreement works right up until a client claims you damaged their hardwood floors. A written service contract should cover the scope of work (which rooms, which tasks, how often), pricing and payment terms, cancellation policies, and who provides supplies.
One federal rule catches cleaning businesses off guard. Under the FTC’s Cooling-Off Rule, if you sign a customer up for a recurring cleaning contract at their home rather than at your office or online, the customer has three business days to cancel without penalty.22eCFR. Title 16 Part 429 – Cooling-Off Period for Sales Made at Homes or at Certain Other Locations The rule applies to sales of $25 or more made somewhere other than your regular place of business. You must provide a written Notice of Right to Cancel and tell the customer verbally about the cancellation right. Failing to do so is treated as an unfair or deceptive practice under federal law.
Keep Up With Annual and Quarterly Filings
Forming your business isn’t a one-time event. Illinois LLCs file an annual report with the Secretary of State and pay a $75 fee each year, due during the anniversary month of formation. Corporations file an annual report as well. Missing the deadline can lead to administrative dissolution, which strips your liability protection until you reinstate.
You’ll also have quarterly payroll tax filings with both the Illinois Department of Revenue (income tax withholding) and the Department of Employment Security (unemployment contributions). Federal payroll taxes are reported quarterly on IRS Form 941, and FUTA annually on Form 940. Set calendar reminders for every due date. Payroll tax penalties accumulate quickly, and the IRS treats payroll tax delinquency more seriously than almost any other compliance failure.
