How to Properly Close (Dissolve) a US LLC
The idea that you can simply stop paying and let a US company fade away is one of the most expensive assumptions a non-resident founder makes. An LLC doesn't quietly disappear — it keeps generating bills and filing obligations until you formally close it, and the penalties for ignoring that can outlast the business by years. Here is how to dissolve a US LLC the right way, in the right order, so it ends clean.
Why "just walking away" is the expensive option
An inactive LLC is not necessarily a free LLC. A registered-agent contract, state annual-report or franchise-tax rules, and federal filing requirements must each be closed deliberately. For a foreign-owned US disregarded entity, Form 5472 applicability depends on ownership and reportable transactions—not whether the EIN remains active or whether the company had revenue. A quiet final year can still contain reportable owner-company transactions. The initial penalty for a required Form 5472 that is late, incomplete, or missed is generally $25,000. See the IRS instructions and our plain-English guide.
Eventually the state may administratively dissolve a company that stops filing — but that is not a clean exit. It can leave unpaid fees, penalties, unresolved returns, contracts, debts, and creditor claims. Reinstating later may require curing those defaults. A deliberate wind-down and state dissolution can stop avoidable future state and registered-agent costs, but it does not erase liabilities or filing duties that already exist.
The order of operations
Sequence matters, but the state cancellation date and the due dates for final federal returns are not always the same. This is a planning sequence; the facts and filing calendars determine which submissions happen first:
- 1. Wind the business down. Settle outstanding debts, collect what's owed to you, and distribute any remaining assets to the owners. Keep the bank account open for now — you'll need it to pay final costs and receive any last funds.
- 2. Determine the final-period filings and dates. Review the short final period, tax classification, payroll, sales tax, reportable owner-company transactions, and other returns. If Form 5472 applies, it is attached to a pro-forma Form 1120 and marked final. If the LLC elected corporate treatment, a full final corporate return may apply instead.
- 3. Coordinate the state dissolution. Bring required state reports or tax current and submit Articles of Dissolution or a Certificate of Cancellation (fees below) at the time that stops avoidable future state charges. Do not delay automatically until a later federal filing date unless the applicable rules require it.
- 4. File every required final return when due. A final federal or state return may be filed after the state has processed the dissolution because its filing date follows the final tax period. Preserve the records and mark each applicable return final.
- 5. Close the EIN account with the IRS. After all required returns are filed and taxes are paid, send the IRS the information it requests to close the business account tied to the EIN.
- 6. End services only when notices can still reach you. Coordinate the registered agent and mailbox with the state cancellation and keep a reliable mailing channel long enough to receive final state, IRS, bank, or provider notices.
State dissolution filings and fees
The formal step in each state is a short filing — Articles of Dissolution in most states, a Certificate of Cancellation in Delaware. The fees are modest and are the smallest part of the total cost; the real expense of a late close is the accumulated reports, franchise tax, and penalties you have to clear first. Here are four states non-resident founders commonly consider, with 2026 dissolution details:
| State | Dissolution filing | State fee | Clear first |
|---|---|---|---|
| Wyoming | Articles of Dissolution | ~$60 | Current annual report |
| New Mexico | Articles of Dissolution | ~$25 | No annual report to clear |
| Florida | Articles of Dissolution | $25 | Any overdue annual report |
| Delaware | Certificate of Cancellation | ~$220 | $400/yr LLC tax paid in full |
Delaware is the outlier in both directions: the highest filing fee and the strictest precondition, since the state won't cancel the LLC until the $400 annual LLC tax is fully paid. New Mexico is the gentlest — no annual report to bring current and a small fee — which is one reason it's a popular home state. For the recurring costs that build up while a company sits open, our guide to annual LLC costs by state shows what you're really on the hook for, and Delaware vs Wyoming vs New Mexico compares them side by side.
Closing the EIN account
People often ask how to "cancel" an EIN. You can't — the IRS never reuses a number or truly deletes it — but you can and should close the business account attached to it once all required final returns are in. The mechanism is a letter to the IRS stating the company's full legal name, the EIN, the business address, and the reason you're closing the account, ideally with a copy of the original EIN assignment notice (the CP 575). It goes to the IRS in Cincinnati, Ohio. Send it after the required final federal filings, not as a substitute for determining what the final period requires.
A realistic timeline
Closing a company cleanly spans more than a single afternoon, mostly because the state and federal calendars are different. The state dissolution itself may be processed well before the filing date for the final federal period. If Form 5472 or another return is required, that work can fall in the following filing season. The practical shape is: wind down, determine final-period transactions and tax treatment, coordinate the state cancellation, preserve the records and reliable mailing channel needed for notices, file each required final return when due, close the EIN account, and then let the last services lapse. If a missed prior-year filing is part of why you're closing, our guide to the $25,000 Form 5472 penalty and our penalty-response service explain how reasonable-cause relief works.
Frequently asked questions
What happens if I just stop paying and walk away?
The company can keep generating obligations. The registered agent may keep billing, and the state can add report fees, tax, and penalties. An active EIN does not by itself create a Form 5472 filing; review the final period's classification and reportable transactions. Administrative dissolution leaves unresolved fees and filing history rather than a clean close.
Do I still have to file a final tax return?
A final federal filing may be required. A foreign-owned single-member LLC treated as a US disregarded entity should review its final short period for reportable owner-company transactions. When Form 5472 applies, attach it to a pro-forma Form 1120, mark the filing final, and file it on the applicable schedule. Missing a required form can trigger the $25,000 initial penalty.
How much does it cost to dissolve an LLC by state?
The filing fee is small and varies — roughly $60 in Wyoming, $25 in New Mexico, $25 in Florida, and about $220 in Delaware, where you must also be current on the $400 annual LLC tax first. The larger cost of a late close is the accumulated fees and penalties, not the filing.
Can I cancel my EIN with the IRS?
An EIN is never reassigned or truly cancelled, but you can close the business account. Send the IRS a letter with the legal name, EIN, address, and reason — ideally with the original EIN assignment notice — to the IRS in Cincinnati, Ohio, after your final returns are filed.
