  • Your name cannot include words that could confuse your LLC with a government agency such as using the words FBI, Treasure, State of Department, etc.

FAQ [Naming an Illinois LLC]

What is an LLC?

LLC is short for Limited Liability Company. LLC is a simple business structure that offers business owners more flexibility compared to a traditional corporation while still providing many of the same benefits. An LLC is one of several different types of business structures, such as sole proprietorship, partnership, and corporation (C corp and S corp).

Do I need to get a DBA or Trade Name for my business?

Most LLCs do not need a DBA since the name of the LLC can already serve as your company’s brand name and you can even accept checks and other payments under that name as well. However, you may also wish to register a DBA if you would like to conduct business under another name.

Step 2: Choose an Illinois Registered Agent

To start an LLC, the Secretary of State requires you to nominate a registered agent for your LLC. A registered agent is also known as resident agents or agents for service of process in other states.

A registered agent can be an individual or business entity that’s responsible for receiving important tax forms, legal documents, a notice of lawsuits, and official government correspondence on behalf of your business. You can think of them as a point of contact for your business with the state.

To nominate a registered agent, you need to make sure that they’re a resident of Illinois, or a corporation, such as a registered agent service, that’s authorized to transact business in Illinois. You may even elect an individual within the company, including yourself as your LLC’s registered agent.

Step 3: File the Illinois LLC Articles of Organization

As mentioned earlier, to register your Illinois LLC, you will need to file the Articles of Organization with the Secretary of State Department either online, by mail, or in person. Now is also a good time for you to determine whether your LLC will be member-managed or manager-managed.

The articles must include:

  • Name and address of LLC’s organizer
  • The LLC’s name and address
  • The name, address, and signature of the LLC’s registered agent
  • The name and address of at least one manager or member

This is important as a comprehensive operating agreement will help ensure that all business owners are on the same page and thus reduces the risk of future conflict.

Important Steps After Forming a Limited Liability Company (LLC)

Separate Your Personal and Business Assets

Your personal assets like your home, car, and other valuables are at risk in the event your Illinois LLC gets sued if your personal and business accounts are mixed. In business law, this is often referred to as piercing the corporate veil. Here are a few steps you can take to protect your Illinois LLC.

1. Opening a business bank account

This is a critical step as it will separate your personal assets from your company’s assets, which is necessary for personal asset protection. It will also make your business accounting and tax filing easier.

2. Getting a business credit card

Though it’s not a must, this is a good habit to practice to help business owners separate their personal and business expenses. This step can also be used to build your company’s credit history, which will prove useful when you want to raise capital or apply for small business loans later on.

3. Hiring a business accountant

Though you certainly can handle your business books yourself, it may often be a good idea to consider hiring a business accountant as they are experts in this field. Business accountants are equipped with the right experience and expertise to help prevent your business from overpaying taxes and to avoid penalties, fines, and other costly tax errors that you might miss out on.

Getting an accountant also makes bookkeeping and payroll much easier, leaving you with plenty more time to focus on plans and strategies that will grow and expand your business. Business accountants can also help you manage your business funding more effectively such as discovering areas of unforeseen loss or extra profit.

Get Business Insurance for your LLC

Getting business insurance is just as important as getting personal insurance. Business insurance helps you manage company risk and focus on growing your LLC in Illinois. The most common types of business insurance available include:

General Liability Insurance – This is a pretty broad insurance policy that protects your Illinois LLC from lawsuits. Most small businesses will get general liability insurance to protect their business.

Professional Liability Insurance – This is an insurance that’s catered for professional service providers such as consultants, accountants, etc. The insurance covers claims of malpractice and other business errors that they may be exposed to.

Workers’ Compensation Insurance – This is a type of insurance that provides coverage for employees’ job-related illnesses, injuries, or deaths. If your LLC has employees, then this is a good insurance to consider.

Create Your Website

In a world of digitalization, creating a website is a big step in legitimizing your LLC in Illinois. Almost every business today will have its own website. Even if you think that your Illinois LLC is too small or you’re focused on an offline industry, you could still be potentially missing out on a large percentage of customers and revenue simply because you don’t have a website or online presence.

Some business owners may fear that creating a business website is out of their reach since they do not have any website-building experience. While this may have been a reasonable fear back in 2015, web technology has seen huge advancements in the past few years that make the life of small business owners much simpler!

Here are a few main reasons why you should seriously consider building your own business website:

  • All legitimate businesses have websites. The size or industry of your business does not matter when it comes to setting up your business online.
  • Social media accounts like Facebook pages or LinkedIn business profiles are simply not enough and do not act as a replacement for a complete business website that you own and control.
  • There are many website builder tools online like GoDaddy Website Builder that have made it their mission to create a website extremely simple. With this, you don’t even need to worry about hiring a web developer or designer just to create a website you can be proud of.

Send Out a Press Release

Though it’s not a requirement in the Illinois Secretary of State to form your LLC, press releases are among the easiest and best methods to promote your business. They’re also one of the most cost-effective strategies that provide plenty of great benefits like:

  • Excellent publicity
  • Establish your brand presence on the web
  • Improves your website’s SEO to drive more customers to your website
  • A one-time cost in terms of effort and money
  • Have long-lasting benefits
