How do you actually close a US LLC?
Not by ignoring it. An abandoned LLC keeps accruing annual fees and penalties until the state administratively dissolves it, and the federal filing obligations do not stop on their own either. Closing properly is a sequence, and skipping steps is what creates the bills people complain about years later.
The essentials
Verified July 28, 2026
- Abandoning it works?
- NoFees and penalties continue to accrue until the state acts, and administrative dissolution is not the same as a clean closure.
- State step
- Articles of DissolutionFiled with the state of formation; name, fee and process vary by state.
- Federal step
- Final return and account closureFiling obligations including Form 5472 for a foreign-owned LLC continue until properly ended.
- Order matters
- Settle, then fileDebts, taxes and final filings are generally dealt with before or alongside dissolution, not after.
What's included
- Filing the Articles of Dissolution with your state of formation
- Confirming outstanding annual reports are current, since most states will not dissolve a delinquent entity cleanly
- A clear record of the closure date for your accountant's final return
What's not included
- Final tax returns, including Form 5472 and the pro-forma Form 1120, which are an accountant's work
- Settling debts, distributing assets or resolving disputes between members
- Closing your bank accounts and payment processor accounts, which you do directly with each provider
Walking away and assuming it lapses harmlessly
This is by far the most common ending for a US LLC and it is the expensive one. Stop filing and the annual report obligation does not stop — Illinois adds a $100 penalty past 60 days and starts administrative dissolution at 120, California keeps assessing the $800 minimum tax, and Florida's late fee is $400. Meanwhile the federal side does not notice you have lost interest: a foreign-owned single-member LLC generally must file Form 5472 with a pro-forma Form 1120 until the obligation properly ends, and the penalty for not filing starts at $25,000. Founders discover this when they try to form a new company and find an unresolved entity behind them. Closing properly costs a filing fee and an accountant's time; not closing properly costs considerably more.
The order of operations
Broadly: wind up the business and settle what it owes, bring state filings current, file the Articles of Dissolution with the state, file a final federal return and close the EIN account, then close bank and processor accounts. The sequence matters because most states will not process a clean dissolution for a delinquent entity, and because your accountant needs the closure date to file correctly.
Administrative dissolution is not the same as closing
If you simply stop paying, the state will eventually dissolve the entity administratively. That is not equivalent to a voluntary dissolution: it typically follows a period of accruing penalties, it leaves a delinquency on the record, and in many states the entity can be reinstated — which means the obligations can come back rather than being finished with. It is the difference between closing an account and having it sent to collections.
The federal side is the part people forget
State dissolution ends the entity's existence under state law. It does not by itself resolve federal filing obligations. For a foreign-owned single-member LLC, Form 5472 with a pro-forma Form 1120 is the obligation that matters, and it is triggered by reportable transactions rather than by profit — so even the year in which you wind down is likely a filing year. Speak to your accountant before you file the state paperwork, not after.
Worth knowing
RazorFile can file the state dissolution and make sure your reports are current. We cannot file your final tax returns, resolve debts, or advise on the order in which creditors and members should be paid — all of which are matters for an accountant or lawyer. If the LLC has debts, contracts still running, or members who disagree, take advice before filing anything.
Common questions
Can I just stop paying and let the LLC lapse?
You can, and it is usually the more expensive route. Penalties accrue until the state acts — $400 in Florida, $100 in Illinois past 60 days, and California's $800 minimum tax continues — and federal filing obligations do not stop on their own. Administrative dissolution leaves a delinquency behind rather than a clean closure.
Do I need to file a final US tax return?
Generally yes, and for a foreign-owned single-member LLC that usually includes Form 5472 with a pro-forma Form 1120 for the final year. Because the obligation is triggered by reportable transactions rather than profit, a wind-down year is normally still a filing year. This is work for an accountant.
What if I have already stopped filing for a few years?
It is fixable, and it is better to fix it than to leave it. Typically you bring the delinquent reports current, pay the accumulated fees and penalties, then dissolve. It costs more than closing on time but far less than an unresolved entity you discover again in three years.
How long does dissolution take?
The state filing follows that state's normal processing queue, which ranges from same-session in Colorado to 15 to 20 business days in North Carolina. The longer part is usually getting filings current and the final return prepared beforehand.
