After you start an Illinois LLC, there are two main types of ongoing filings. The first is the Annual Report with the state, and the other is taxes.
Paying taxes is an important part of running a business, but figuring out which taxes you need to pay can be a pain.
This lesson will provide you with general resources and the basics of Illinois LLC tax filing requirements.
What taxes does a Limited Liability Company pay in Illinois?
Each LLC has a different tax situation, so the taxes paid for an Illinois LLC varies.
The amount of taxes owed for your LLC depends on rules like:
- how your LLC is taxed
- state and local tax rules
- any sales and use tax requirements, or
- whether you have employees
Additionally, some business types are required to register for industry-specific taxes.
Pro Tip: We recommend hiring an accountant to ensure your LLC meets all of its tax obligations.
We also recommend getting an EIN Number for your LLC. An EIN is also called a Federal Tax Identification Number. They mean the same thing.
Not only will an EIN number be used to open an LLC bank account, but it will also be used for filing taxes with the local, state, and federal governments.
LLC pass-through taxation (Who pays the taxes?)
By default, LLCs don’t pay taxes.
Instead, the LLC Members are responsible for reporting the income (or losses) on their personal 1040 tax return. The Members pay taxes on any LLC profits. This is because of LLC pass-through taxation.
Simply put, pass-through taxation means the responsibility for reporting tax information from an LLC “passes through” the LLC to the LLC Members.
How are LLCs taxed in Illinois?
By default, an Illinois LLC is taxed by the Internal Revenue Service (IRS) based on the number of Members the LLC has. Then the Illinois Department of Revenue honors this and taxes your LLC the same way at the state level.
An LLC with 1 owner (Single-Member LLC) is taxed like a Sole Proprietorship.
An LLC with 2 or more owners (Multi-Member LLC) is taxed like a Partnership.
The above are referred to as the “default status“. Meaning, they are automatically applied based on the number of LLC Members.
Alternatively, you have the option of requesting an “elective status” for your LLC. This is done by filing an extra form with the IRS. Once granted, this elective status means the IRS will treat your LLC as a Corporation (either an S-Corporation or C-Corporation) for tax purposes.
Note: Your Illinois LLC Operating Agreement should also include information about how your LLC is taxed.
Federal Income Taxes
There are several different options for how the IRS can treat your LLC for tax purposes.
Single-Member LLC taxes (default status)
The IRS treats all Single-Member LLCs as Disregarded Entities for tax purposes. This just means that the IRS doesn’t expect the LLC to file its own federal income tax return.
Instead, the owner of the Single-Member LLC files the return (and pays the federal income taxes).
How the LLC pays federal income tax is determined by who owns the LLC:
- If the LLC is owned by an individual, the LLC is taxed like a Sole Proprietorship.
- If the LLC is owned by another company, the LLC is taxed as a branch/division of the parent company.
Multi-Member LLC taxes (default status)
If an LLC has two or more owners, the LLC is taxed like a Partnership.
The LLC needs to file a 1065 Partnership Return and issue a Schedule K-1 to the LLC owners.
The K-1s report each owner’s distributive share of profits. And the K-1 income “flows through” to the owners. The income taxes are then paid by each owner on their personal income tax return (Form 1040).
Husband and Wife LLC taxes
You may have heard that in some states, a husband and wife LLC has the option to file taxes as a Single-Member LLC (aka Qualified Joint Venture) instead of a Multi-Member LLC.
This is true for community property states (like Texas). That said, Illinois isn’t a community property state, which means Qualified Joint Ventures are not available in this state.
Electing to have your LLC taxed as a Corporation
Instead of the default statuses above, a Limited Liability Company (LLC) can be taxed like a Corporation.
Note: We recommend speaking with an accountant before making a corporate election.
There are two types of corporate elections:
LLC taxed as an S-Corporation (elective status)
By filing Form 2553 with the IRS, your LLC can request to be taxed like an S-Corporation.
Being taxed as an S-Corp can help businesses (with established profits) save money on self-employment taxes.
Tip: There are additional expenses to having your LLC taxed as an S-Corporation Most new business owners shouldn’t make this tax election until their business is established and revenue is consistent. Once there is at least $70,000 in annual net income per LLC Member, we recommend speaking to your accountant about this option.
LLC taxed as an C-Corporation (elective status)
By filing Form 8832 with the IRS, your LLC can request to be taxed like a C-Corporation.
Being taxed as a C-Corp can help large employers save money on healthcare fringe benefits.
Note: This election is not common. Most of our readers don’t choose to have their LLC taxed as a C-Corporation.
Illinois State Income Tax for Illinois LLCs
Single-Member LLCs in Illinois: The LLC itself usually doesn’t file a state-level return. However, the owner files a personal state-level return that includes the LLC’s profits or losses.
Multi-Member LLCs in Illinois: The LLC itself may need to file a Partnership return at the state-level. And the owners file a personal state-level return that include the LLC’s profits or losses.
There are other types of Illinois business tax that apply to certain industries and types of businesses.
We recommend hiring an accountant to prepare and file your state income taxes.
Personal Property Replacement Tax
Illinois LLCs are also required to pay 1.5% of their net income to the Illinois Department of Revenue. This is called the Personal Property Replacement Tax.
Illinois Tax ID Number
All businesses in Illinois should get an Illinois state-level Tax ID number.
You can register your LLC for an Illinois Tax ID number and business taxes online through MyTax Illinois.

Local Income Tax for Illinois LLCs
You and/or your LLC may need to file and pay income taxes with your local municipality (town, city, county, etc.).
We recommend hiring an accountant to prepare and file your local income taxes.
You can also contact your municipality to check on their requirements.
Illinois Sales Tax
If you sell products to consumers in Illinois, you are required to collect sales and use tax and get a Sales & Use Tax license. You can get a Sales & Use Tax license from the Illinois Department of Revenue (IDOR).
A Sales & Use Tax license is the license that allows you to collect sales tax on retail sales in the state where you do business. It’s sometimes also called a:
- seller’s permit
- resale license
- wholesale license
- sales tax permit/license
- reseller permit
They all mean the same thing and we may use these terms interchangeably.
You can register for Sales & Use Tax online through MyTax Illinois.
And you can read more information about Illinois sales and use tax from these IDOR resources:

Illinois LLC Payroll Taxes
If your Illinois LLC will have employees, you must submit payroll taxes. Payroll taxes are essentially a group of taxes and filings, including:
- Federal income tax withholding
- State income tax withholding
- Social Security tax
- Medicare tax
- Federal unemployment taxes (FUTA)
- State unemployment taxes (SUTA)
- Local/county deductions
- Employee deductions
As an employer in Illinois, you need to set up payroll, withhold payroll taxes from employees’ paychecks, and then submit those filings and taxes to various state and government agencies.
Although you can file payroll taxes yourself, the calculations can be burdensome and very complex. And if done improperly can lead to penalties and fines. Most people hire a payroll company or ask their accountant for help.

Illinois LLC Taxes FAQs
Do I have to pay an annual fee for my LLC in Illinois?
Yes, all Illinois LLCs have to pay an annual fee by filing a Illinois LLC Annual Report every year. This is separate from the federal, state, and local taxes that you pay.
The LLC Annual Report is filed with the Illinois Secretary of State. It is not a tax paid to the Illinois Department of Revenue.
The Annual Report for Illinois LLCs costs $75 per year. This is paid every year for the life of your LLC.
How much is an LLC in Illinois?
Illinois LLC Costs include:
$150 to form your Illinois LLC (to file your LLC Articles of Organization).
$75 in annual fees (to file your LLC Annual Report) for an Illinois LLC.
Do I need to file an Illinois state tax return for my LLC?
Maybe – it depends on what type of LLC you have.
Single-Member LLC taxed as a Sole Proprietorship: No. You only need to file your personal tax return (Federal Form 1040 and Illinois Form IL-1040) and include your LLC profits on the return.
Multi-Member LLC taxed as a Partnership: Yes. Your LLC must file a IRS Form 1065 and an Illinois Partnership Return (Form IL-1065).
LLC taxed as a Corporation: Yes. Your LLC must file tax returns with the IRS and the Illinois Department of Revenue to pay your Illinois income tax. Check with your accountant to make sure you file all the correct documents.
How do I know my LLC tax classification?
You can tell your LLC’s tax classification by looking at how many Members are in your LLC.
This is because LLCs receive their tax classification from the IRS based on the number of Members (owners) your LLC has.
If you have one Member, your LLC is taxed as a Sole Proprietorship.
If your LLC has more than one Member, your LLC is taxed as a Partnership.
This is called being taxed in your default status. Meaning, you don’t have to file any paperwork to let the IRS know that’s how your LLC will be taxed because they tax LLCs that way by default.
However, in order for your LLC to be taxed as a Corporation, you or your accountant would have to file paperwork with the IRS letting them know you’ve chosen to be taxed as a Corporation.
And then the IRS would mail you an Approval Letter to confirm you’ve chosen the Corporate tax election for your LLC.
Note: Being taxed as a Corporation is rare for LLCs, so most people don’t need to worry about this.
And if you’re still unsure about how your LLC is taxed, we recommend calling your accountant or the IRS (1-800-829-4933). To speak to a live person at the IRS, press option 1, option 1 again, and then option 3.
