How to Dissolve an LLC in Illinois (Complete Guide)

To dissolve an LLC in Illinois, you need to settle all outstanding state taxes with the Illinois Department of Revenue, then file Articles of Dissolution with the Illinois Secretary of State. The state filing fee is just $5, one of the cheapest in the country, and standard processing takes 4 to 8 weeks. Before filing, LLC members must vote to dissolve, and all business debts and obligations must be wound up.

Illinois has one of the lowest dissolution filing fees in the United States, but the tax side of the process is where most people get tripped up. Prodezk, the company behind DissolveMyLLC, has served over 15,000 businesses across 193 countries. Here is the exact process for dissolving an Illinois LLC, including the steps people commonly miss.

What Does It Mean to Dissolve an LLC in Illinois?

Dissolving an Illinois LLC is the legal process of formally ending its existence with the state under the Illinois Limited Liability Company Act (805 ILCS 180/). This is different from simply closing your bank account or stopping operations. Until you file Articles of Dissolution with the Illinois Secretary of State, your LLC stays active and keeps accruing obligations.

An active Illinois LLC owes a $75 annual report fee to the Illinois Secretary of State every year, even with zero revenue. Dissolution is the only way to permanently end this obligation.

Illinois requires every LLC to file an annual report and pay a $75 fee by the first day of the LLC's anniversary month of formation. LLCs with more than $10,000 in paid-in capital also owe a franchise tax. Skipping these filings does not make the LLC disappear. It triggers penalties and eventually administrative dissolution. Formally dissolving the LLC eliminates both the annual report fee and the franchise tax obligation for good.

The dissolution process has four main phases: voting to dissolve, settling state tax obligations with the Illinois Department of Revenue, filing Articles of Dissolution with the Secretary of State, and closing out federal accounts. Skip a step and you risk a rejected filing or lingering liability.

Step 1: How Do You Vote to Dissolve Your Illinois LLC?

The Illinois Limited Liability Company Act requires LLC members to formally approve the decision to dissolve. The voting threshold depends on your operating agreement. If your operating agreement does not address dissolution, Illinois law requires the consent of all members.

For a single-member LLC, this is simple. You sign a written resolution stating your intent to dissolve the LLC, date it, and keep it with your business records.

Illinois law requires written documentation of the dissolution decision. A signed resolution with the date, member names, and vote outcome protects you if the dissolution is ever questioned.

For multi-member LLCs, check your operating agreement first. Most agreements specify a majority or two-thirds vote for dissolution. If there is no operating agreement, unanimous member consent is required under Illinois law. Document the vote in meeting minutes or a written consent resolution signed by all voting members.

After the vote, the LLC enters a winding up period. During this time the LLC should stop taking on new business and focus on settling debts, collecting receivables, and distributing remaining assets to members.

Step 2: How Do You Settle Taxes with the Illinois Department of Revenue?

Illinois expects your LLC to be current with the Illinois Department of Revenue before you wrap up the entity. This means filing a final tax return and clearing any outstanding state tax liabilities, including sales tax, withholding tax, and any franchise tax owed.

If your LLC had more than $10,000 in paid-in capital, you owe Illinois franchise tax, and a final franchise tax return must be filed. If your LLC collected sales tax or had employees, you must file final returns for those accounts through MyTax Illinois at mytax.illinois.gov.

The Illinois Department of Revenue requires all state tax returns to be filed and all balances paid before an LLC is considered fully wound up. Unresolved tax liabilities can follow members personally after dissolution.

In our experience working with Illinois clients, the tax step is where most delays happen. If your LLC has fallen behind on annual reports or state tax filings, you need to catch up before the dissolution is clean. Filing Articles of Dissolution while you still owe back taxes or unfiled returns leaves the door open to collection actions against members during the lookback period.

Step 3: How Do You File Articles of Dissolution with the Illinois Secretary of State?

Once your tax obligations are settled, file Articles of Dissolution (Form LLC-35-15) with the Illinois Secretary of State. The filing fee is just $5, which is one of the lowest dissolution fees of any state.

You can file online through the Illinois Secretary of State website at ilsos.gov, or you can submit by mail to the Department of Business Services, Limited Liability Division, 501 S. Second St., Rm. 351, Springfield, IL 62756. Online filing is faster and gives you immediate confirmation of receipt.

The Articles of Dissolution require the LLC's exact legal name, its Illinois file number, the reason for dissolution, the effective date, and confirmation that the dissolution was properly authorized by the members. Make sure the name matches your formation records exactly. A mismatch is one of the most common reasons filings get rejected.

The Illinois Secretary of State charges a $5 filing fee for Articles of Dissolution (Form LLC-35-15). Standard processing takes 4 to 8 weeks, and can run longer during peak filing periods.

Standard processing takes 4 to 8 weeks. Peak periods, typically early in the year, can stretch the timeline further. After the Secretary of State approves the filing, the LLC is officially dissolved and your annual report obligation ends.

Step 4: How Do You Handle Federal and Bank Closures After Dissolving Your Illinois LLC?

Filing with the state is not the last step. You also need to close your LLC's federal obligations and shut down any remaining financial accounts.

To close your EIN with the IRS, send a letter to the IRS that includes the LLC's legal name, EIN, mailing address, and a statement that you want to close the business account, along with the reason. The IRS has no specific form for this. A written letter is the accepted method.

If your LLC was a multi-member LLC taxed as a partnership, file a final Form 1065 with the IRS, check the "final return" box, and issue final K-1s to all members. For a single-member LLC, file a final Schedule C with your personal return and mark it as the final filing for the business.

The IRS does not automatically close your EIN when Illinois approves your dissolution. You must notify the IRS in writing separately. Skipping this can trigger notices for unfiled federal returns in future years.

Close your business bank accounts, cancel any business licenses or permits at the city, county, or state level, and cancel insurance policies tied to the LLC. If the LLC had employees, file final payroll tax returns (Form 941 for quarterly, Form 940 for annual FUTA) and issue final W-2s.

How Long Does It Take to Dissolve an LLC in Illinois?

The total timeline for dissolving an Illinois LLC is typically 6 to 12 weeks from start to finish. This breaks down as follows: settling tax obligations with the Illinois Department of Revenue takes 1 to 4 weeks depending on how current your filings are, filing Articles of Dissolution takes 4 to 8 weeks for standard processing, and closing federal accounts adds another 1 to 2 weeks.

The biggest variable is the tax side. If your LLC is current on annual reports and state tax filings, the process moves smoothly. If you need to file back annual reports or pay overdue franchise tax, add several weeks to resolve those before the dissolution is clean.

In our experience, most Illinois LLC dissolutions that are current on taxes take 6 to 10 weeks total. Delinquent LLCs can take 10 to 16 weeks once back filings and penalties are resolved.

What If Your Illinois LLC Was Administratively Dissolved?

If your Illinois LLC failed to file its annual report or pay the $75 annual fee, the Illinois Secretary of State can administratively dissolve it. This is not the same as a voluntary dissolution you control. The state ends the entity for noncompliance, but unresolved tax and debt obligations can still follow the members.

An administratively dissolved LLC can be reinstated within a set window by filing for reinstatement, paying all back annual reports, and clearing penalties. Whether you reinstate then voluntarily dissolve, or simply resolve the outstanding obligations, depends on your situation. In many cases, settling back filings and confirming the administrative dissolution is the cleanest path to a final close.

Illinois can administratively dissolve an LLC for failure to file annual reports. The entity may still carry tax and debt obligations, and Illinois applies a 5-year lookback period for LLC liabilities after dissolution.

To resolve an administratively dissolved Illinois LLC, the key is closing out all outstanding annual reports and state tax balances so nothing lingers against the members during the 5-year lookback. The exact filings depend on how many years of reports are missing and whether franchise tax is owed.

What Are the Most Common Mistakes When Dissolving an Illinois LLC?

After handling thousands of dissolution cases, these are the mistakes we see most often with Illinois LLCs.

Ignoring the final tax return. Illinois expects a final tax return with the Department of Revenue and, where applicable, a final franchise tax return. Skipping this leaves a balance that can follow members personally for years.

Leaving annual reports unfiled before dissolving. Outstanding $75 annual reports do not vanish when you stop operating. They accumulate penalties and can block a clean wind-up until resolved.

Filing with the wrong LLC name. The Articles of Dissolution must match your formation records exactly. A small mismatch in the legal name is one of the top reasons Illinois rejects a filing.

Forgetting to close the EIN with the IRS. State dissolution does not touch your federal tax account. If you do not notify the IRS, they may keep expecting annual returns, which leads to automated penalty notices.

Assuming administrative dissolution ends everything. Being administratively dissolved by the state stops the entity, but tax and debt obligations can still follow members during the 5-year lookback period. You still need to resolve the outstanding items.
