Step 1: Choose a Name for Your LLC

Timeframe: Filing the Articles of Organization typically takes around one to two weeks. However, if you choose to file online, you may receive confirmation of your LLC’s approval within a few days.

Timeframe: Obtaining an EIN can usually be done quickly online, and you will receive your number immediately.

Step 4: Apply for Business Licenses and Permits

Depending on the type of business you plan to operate, you may need to apply for additional licenses and permits from the state or local government. This can include things like a business license, sales tax permit, or professional license.

If you are in a hurry to get your LLC up and running, you may want to consider using an online formation service, which can expedite the process significantly.

However, if you have a more complex business structure or need to apply for multiple licenses and permits, it may take longer to complete the process.

Do I Need to Get a Business License for My Illinois LLC?

In Illinois, businesses are not required to obtain a state-level business license or operating license. However, it is important to note that local municipalities may mandate at least one type of business permit or license before starting operations in the state.

Although a statewide business license is not mandatory, businesses are required to obtain a Certificate of Registration or License, commonly known as a seller’s permit, if they intend to sell or lease taxable goods or services within Illinois. This permit is essential for compliance with the state’s sales tax laws and regulations.

Therefore, it is crucial to check with the local municipality and obtain a seller’s permit before beginning operations in Illinois.

Should I Hire an LLC Filing Service in Illinois?

Whether or not to hire an LLC filing service in Illinois depends on your specific needs and circumstances.

An LLC filing service can be helpful if you’re unfamiliar with the formation process, need assistance with paperwork and filing, or simply want to save time and hassle. LLC filing services can take care of the paperwork and filing process for you, so you can focus on running your business. Additionally, some LLC filing services may offer additional services, such as registered agent services or tax advice.

However, if you’re comfortable with the formation process and have the time and resources to handle the paperwork and filing yourself, hiring an LLC filing service may not be necessary.

You can file the Articles of Organization yourself by mail or online, and the process is generally straightforward. Additionally, hiring an attorney or accountant to review your documents and provide guidance can be a more cost-effective option than hiring an LLC filing service.

Ultimately, the decision to hire an LLC filing service in Illinois is a personal one and depends on your specific needs and circumstances. It’s always recommended to do your research, compare costs and services, and consult with professionals before making a decision.


In summary, while the process of obtaining an LLC in Illinois can take a bit of time, it is a relatively straightforward process that can be completed with a little bit of effort and attention to detail.

By following the steps outlined above, you can get your LLC up and running and start pursuing your entrepreneurial dreams in no time.
