How to dissolve an Illinois LLC

Step 1: Decide, and put the decision in writing

For a single-member LLC the decision is yours alone, but write it down anyway. A short written consent or a note in your operating agreement records that the member voted to dissolve, and on what date. If your operating agreement sets a dissolution procedure, follow it. This document looks trivial and is not. Banks, tax authorities, and anyone you owed money to may ask when the business decided to close, and a dated record answers cleanly. Pick the date deliberately. Many owners close at the end of a tax year so the final returns are the last returns, with no short extra year to file.

Step 2: Wind up the business

Dissolving is the legal event. Winding up is the work around it, and it comes first in practice. Finish or hand off open client work. Collect what customers owe you, and pay what the business owes: vendors, contractors, taxes, and the final payroll if you have employees. Cancel subscriptions, insurance you no longer need, and recurring charges in the LLC's name. Keep the business bank account open through this stage. You need it to receive final payments and pay final bills. Closing the account early strands money in both directions.

Step 3: File the Statement of Termination

The state filing is Form LLC-35.15, the Statement of Termination, and the fee is $5. File it with the Secretary of State once the decision is made and the winding up is underway. Before you file, make sure the LLC is in good standing. An LLC that is behind on annual reports may need to settle those first, since the state expects the record to be current before it closes the file. Once the termination is accepted, the LLC no longer exists as an entity. Contracts, accounts, and registrations that still reference it need the closing steps below to match.

Step 4: Close the tax accounts

File final tax returns for the LLC's last year, and mark them final. For a disregarded single-member LLC, the business income appears on your personal return one last time, including any income collected during the wind-up. Close your Illinois Department of Revenue business registration so sales tax and withholding accounts stop expecting filings. An open account that receives no returns generates notices, and notices generate penalties for a business that no longer exists. If the LLC had employees, close the Illinois Department of Employment Security account as well and file the final payroll reports. If the LLC had its own EIN, the IRS does not cancel EINs, but you can close the business account with the IRS by letter so the number stops expecting returns.

Step 5: Cancel licenses, permits, and registrations

Every license the LLC held needs its own goodbye. Local business licenses, professional licenses, and permits do not cancel themselves when the state dissolves the entity. Neither do assumed name filings, local registrations, or accounts with marketplaces and payment processors. Work from a list. Check the city or county where you registered, any agency that licensed the work, and any platform that paid you. Cancel the business insurance last, once operations have truly stopped, and ask whether a tail policy makes sense if clients could bring claims about completed work.

What not to do

Do not just stop filing annual reports. Administrative dissolution follows, and it is the same destination reached the costly way: penalties accrue, the LLC loses good standing and possibly its name, and the owner still has to do most of the wind-up work with less control over the timing. Do not empty the bank account before final taxes are estimated. A tax bill that arrives after the account is closed is a personal errand. And do not assume dissolution erases debts. The LLC's obligations survive the filing until they are paid or otherwise resolved, and debts you personally guaranteed were always yours.

After it is closed

Keep the records: formation documents, the termination filing, final returns, and bank statements. Illinois owners generally keep business tax records for years after the last return, and a closed LLC generates questions at odd times, from a client's accountant to your own. Store the file and move on. Closing a business cleanly is a skill, and the next one starts faster for it.
