Before continuing with our article, let’s establish the role of a registered agent is.

What Is a Registered Agent?

A registered agent is an individual or a company whose job is to keep you compliant with all the laws and regulations of your state and receive your correspondence on your behalf. 

What Are the Benefits of Getting a Registered Agent?

There are various benefits to appointing a registered agent.

For starters, registered agents allow for more privacy. You won’t need to share your home address in public; instead, you can use your registered agent’s physical address.

Registered agents can protect you from awkward encounters with your customers and clients. If you’re to personally receive a lawsuit or a claim, you risk getting served in front of your customers. Registered agents allow for that to be done in a private manner.

Last but not least, registered agents help you be more at ease since you won’t have to worry about missing any deadlines or getting fined.

Does Illinois Require a Registered Agent?

First things first, let’s start by answering the question of whether or not getting a registered agent is a requirement in Illinois.

Both domestic and foreign businesses are required to appoint and maintain a registered agent. There are no limitations in terms of who you can choose – the registered agent can be both a domestic and a foreign entity. If you want, you can appoint yourself as your own registered agent, but you need to be wary of all the potential drawbacks, such as a lack of privacy.

How to Register a Business in Illinois

Find a Name for Your Business

One of the first steps to opening a business is choosing what to name it. Every state has different regulations in terms of what your name can and can’t contain. In every state, you’re required to choose a name that’s available and not taken by any other business. To help you in this regard, you can do a name search online.

If you’re starting an LLC, you have to use the phrase “limited liability company” or some of its abbreviations, such as LLC.

 If you’re starting a corporation, the name has to contain “corporation”, “incorporated”, “limited” or any abbreviation of the above.

There are certain words that are off limits, typically those that imply an association with a government agency such as FBI or State Department.

Choose the Right Business Structure

Now that you have a name for your business, it’s time to choose a business structure.

There are four main types of business structures in Illinois:

  • Sole proprietorship
  • Partnership
  • LLC (Limited Liability Company)
  • Corporation

The main difference between a sole proprietorship/partnership and an LLC/corporation is that the latter provide limited liability to their members, which means that in case of a lawsuit or a claim, the personal assets of the members will remain protected. With that said, sole proprietorships and partnerships are much easier and cheaper to from, making them a great starting point for those who are starting with a lower budget.

File Articles of Organization

If you decide to start an LLC in Illinois, you need to file articles of organization with the state. In short, articles of organization is a document that entails basic information regarding your business, such as its name, location, and the name of the owners.

This document is imperative to separate your LLC from its owners. You can file articles of organization online on the Government of Illinois website.

File Articles of Incorporation

If, on the other hand, you decided to start a corporation in Illinois, you will need to file articles of incorporation with the state. Articles of incorporation is a document that has a similar purpose to articles of organization – it’s essential for the incorporation process of your business and for separating the owners from the business.

The application process is also conducted online and the application fee is $150.

Get an EIN (Employee Identification Number)

If you want to hire employees for your business, or if you want your business to be taxed separately from you, then you’ll also need to apply for an EIN.

An EIN is like a Social Security Number for your business. It’s issued by the IRS and the entire application is online, free of charge.

In addition to getting an EIN for taxation purposes, many business owners choose to obtain one because it makes it easier to open a bank account in certain states.

Obtain Business Licenses and Permits

Last but not least, you’ll need to ensure that you have all the necessary licenses and permits for your business to function legally. Licenses and permits are given on three different levels: federal, local, and state.

Luckily, there is an easy way to check what kind of licenses and permits you’ll need – by doing a business license search. This will show you all the documents you’ll need depending on what industry you’re in.

Many states require businesses to have a general business license, but Illinois is not one of them. However, you’ll need to obtain a Certificate of Registration/License, also known as a seller’s permit, if you intend on selling goods or services in the state.
