1. Name Your Illinois LLC

A good number of business owners can brainstorm with their friends or colleagues that they can rely on, whereas others can use online business name generators to get ideas. Such tools may be useful, but they cannot substitute the consideration of decisions as they might overlook industry peculiarities or branding issues.

After creating a list of shortlist of names, do a business name search via the Illinois Secretary of State site. This will prevent the use of a name that is already used or too close to an existing business. A general internet search and domain availability is also to be carried out to ensure that you do not confuse with other companies.

Illinois requires that your LLC name be followed by the words Limited Liability Company or any acceptable abbreviation (LLC or L.L.C.) and shall not consist of words that may lead to confusion with a governmental agency.


Also, business name should not be similar to any other business names registered in the state and should not use forbidden term like bank, insurances, and university unless the state permits it and also should not make it appear that the LLC is a company or partnership.

Once the availability has been established at the state level, it is prudent to go to the US Patent and Trademark Office (USPTO) database to see whether the name is a federal trademark. This assists in safeguarding your brand and this avoids litigation in the future.

Name Reservation Illinois LLC

The department of business services is the name of the third department
Limited Liability Division
501 S. Second St., Room 351
Springfield, IL 62756

The name is held during a period of 90 days after approval and this gives you time to finish the other formation process.

What is the name of the business? Doing Business As (DBA) in Illinois

In some cases, an LLC is obliged to work under a different name other than its legal name. This is where a DBA or as it is called in Illinois an assumed name comes in handy. To illustrate, when your LLC is named JJ Waffles, LLC and you wish to conduct the sale of baked goods by the name JJ Muffins, you could post that name as an assumed name. An LLC is allowed to have a number of DBAs under the same legal entity.

By registering an assumed name, you are able to open bank accounts, accept payments and promote your business using the DBA. In Illinois, the assumed names are registered at the office of the Secretary of State and you will require the file number of your LLC in order to fill the application.

The rights under assumed names are valid until the first day of the LLC anniversary month in the following calendar year which is divisible by five. They are then renewed after every five years. The prices are as follows: fees depend on the year and are between 30 and 150, and other payment processor fees. Illinois has both regular and fast processing with expedited processing being handled within 24 hours.

2. Select a Registered Agent

The Illinois LLC requires a registered agent. The registered agent will also take care of accepting official papers like legal notices, state correspondence and tax forms on behalf of your business. This is to make sure that your LLC does not miss crucial deadlines or legal correspondence.

They should be 18 years, have a physical street address in Illinois (no P.O. Boxes), and must be available during regular business hours. In case of a business agent it should be licensed to conduct business in Illinois.

The reason is that many owners of LLCs prefer to outsource the services of a professional registered agent. Although this increases the yearly expenditure marginally, it offers privacy, reliability, and flexibility, particularly among the business owners who work at home, do a lot of traveling or do not want their personal address published in public documents.

3. Decide Your Management Organization

A manager can be a member of the organization, but he or she must have at least one manager who is not a member. This is the most suitable type of LLC that has many owners that do not want to be involved with daily operations of the company.

In case you fail to specify a management structure in your Articles of Organization, the state of Illinois will consider your LLC member-managed. The reason why selecting the right structure is also relevant is that it influences authority, liability and decision making.

This individual is known by the IRS as the responsible party. The person who is in control, manages, or directs the entity and its masses and assets is the responsible party. Other than the government, the party in question is required to be an individual, and not another business or entity.

7. Acquire Business Licenses and Permits

Depending on the nature of your business and a place you are located, you might require federal, state, or local licenses and permits.

The inability to receive the appropriate licenses may lead to fines or penalties, and that is why it is crucial to check the requirements with state and local authorities or address a business attorney.

8. Determine Your Tax Status

The Illinois LLCs are taxed by default as a pass-through entity, this is, the LLC does not pay income tax. Profits and losses are instead transferred on to the personal tax returns of the owners.

C-corporation or S-corporation tax status is also available with LLCs. C-corporations are subject to the double taxation and might be beneficial to businesses that hold earnings.
