Close your US LLC the right way.
No IRS surprises two years later.
Closing a US LLC is a sequence, not a single filing: Articles of Dissolution at state, final Form 5472/1120 marked FINAL, EIN cancellation to IRS, state tax closure, bank and vendor notices. Miss any and penalty notices keep arriving. Monezzi runs the sequence in order.
Focus on your customers, we will handle the bureaucracy.

Why formal dissolution is the only safe close
A US LLC does not stop costing you money the day you stop using it. Annual reports, franchise tax, IRS notices and Form 5472 penalties all keep accruing until every layer — state, IRS, FinCEN, vendors — has been formally closed.
Legal closure at the state
Articles of Dissolution remove the entity from Secretary of State records. Without them, the state keeps billing annual report and franchise fees and can administratively dissolve you with penalties attached.
No drifting tax obligations
A federal final return — Form 5472 and 1120 marked FINAL — tells the IRS to stop expecting filings. The $25,000 Form 5472 penalty for non-filing accrues silently if you walk away without it.
Personal liability limited
Once the entity is dissolved on record and final returns are filed, future claims against the LLC have no live counterparty. Walking away informally leaves the door open for years.
Clean bank and vendor closure
A formal dissolution letter is what Mercury, Relay, Stripe, your registered agent and your address provider need to close your accounts cleanly — without it they keep auto-renewing.
Dissolution is a sequence across three agencies. The forgotten parts are where penalty drift starts.
Form 5472 and Pro-Forma 1120 both have a FINAL RETURN checkbox. Founders who file state dissolution and walk away leave that box unchecked — and the IRS keeps expecting a return next year. The $25,000 Form 5472 penalty for non-filing accrues per year.
State dissolution does not touch the IRS. The EIN stays open until you send a written cancellation letter per the Form 966 procedure. If a stray 1099 arrives in your LLC name two years later, the IRS still has a live EIN to chase.
FinCEN expects a final BOI report when the company ceases to exist. Missing it puts you in the same civil-penalty bucket as never filing the initial BOI in the first place. Penalty drift starts the day after the deadline.
"We have seen founders dissolve at the state level and walk away — then receive an IRS notice two years later because their EIN stayed open and a 1099 came in their LLC name. Dissolution is a sequence, not a single filing. We run all five steps because skipping any one of them is what creates the penalty drift founders come to us to clean up."
Dissolution Overview & Key Details
A US LLC dissolution touches three independent agencies — the Secretary of State of the formation state, the IRS, and FinCEN — plus your bank, registered agent and any vendors who hold your EIN. Each one has its own form and its own deadline. We coordinate the sequence so nothing is forgotten.
Who needs it
Any US LLC owner who is winding down the business — voluntary closure, project ended, restructuring under a new entity, or moving operations out of the US. Foreign-owned single-member LLCs especially, because the Form 5472 penalty makes silent abandonment expensive.
How dissolution works
Articles of Dissolution at the state, final Form 5472 and 1120 with the FINAL box checked, EIN cancellation letter to the IRS per Form 966 procedure, state tax account closure, and BOI final report at FinCEN. We file each of these in the correct order.
Processing time
State acknowledgment of Articles of Dissolution typically lands in about 30 days, depending on the state. IRS and FinCEN have their own queues. We do not promise a fixed close date — the agencies control that.
EIN is permanent
The IRS never reuses an EIN. Once dissolved and the cancellation letter is processed, that EIN stays in IRS records tied to the legal entity that owned it. If you form a new LLC later it gets a new EIN, even if the new entity uses the same trade name.
How we assist — five steps, in order
Each step has a dependency. Skipping one is what creates the penalty drift founders come to us to clean up later.
Articles of Dissolution — filed with the Secretary of State
We confirm any outstanding annual report or franchise tax is settled first (the state will not process dissolution until they are), prepare the Articles of Dissolution in the format your formation state requires, and file with the Secretary of State. You receive the state acknowledgment as the official proof of closure.
Final federal tax returns — Form 5472 and 1120 marked FINAL
For foreign-owned SMLLCs we file the final Form 5472 attached to a Pro-Forma 1120 with the FINAL RETURN box checked. Multi-member LLCs, S-Corps and C-Corps get their correct final return. This is what tells the IRS to stop expecting future filings.
EIN cancellation letter — sent to the IRS
We send the written cancellation letter per the Form 966 procedure, including the EIN, the legal name, the original SS-4 address and the reason for closure. The IRS closes the EIN business account — the EIN itself is permanent and is not reused.
State tax account closure — sales, payroll, franchise
If your LLC was registered for state sales tax, payroll withholding or franchise tax, each of those accounts is closed separately at the state revenue department. Otherwise they keep generating notices long after the LLC is dissolved.
Final notices — BOI at FinCEN, bank, registered agent, vendors
We file the BOI final report at FinCEN, then notify your bank, registered agent, US address provider and any vendor holding your EIN (Stripe, Mercury, Relay, Amazon, Etsy, Shopify) that the entity is dissolved. Auto-renewals stop, the entity is fully closed across every record.
Frequently Asked Questions
Answers to common questions about closing a US LLC cleanly across state, IRS and FinCEN.
A clean dissolution is a sequence, not a single filing. (1) File Articles of Dissolution with the Secretary of State of the formation state. (2) File final federal returns: Form 5472 and Pro-Forma 1120 for foreign-owned SMLLCs, each marked FINAL. (3) Send EIN cancellation letter to the IRS. (4) Close state tax accounts (sales tax, payroll, franchise). (5) Notify your bank, registered agent and vendors.
For a foreign-owned single-member LLC, the final return is Form 5472 attached to a Pro-Forma 1120, both with the FINAL RETURN box checked. The IRS treats unchecked or unfiled final returns as an active business, and a $25,000 Form 5472 penalty can accrue silently. Multi-member LLCs, S-Corps and C-Corps each have their own final return rules — Monezzi files the correct one for your entity.
Yes — and most founders skip it. The state dissolves the legal entity. The IRS keeps the EIN open until you send a written cancellation letter (per IRS Form 966 procedure) that includes the EIN, the legal name, the address from the original SS-4 and the reason for closure. Until that letter is processed, the EIN stays active and a stray 1099 in your LLC name can pull the IRS back to you.
Yes, and it depends on the state — Wyoming charges $60, Delaware charges $204 plus settlement of any outstanding franchise tax, New Mexico is $25. The state will not process the Articles of Dissolution until any outstanding annual report or franchise tax is settled first. For Monezzi subscribers our dissolution service is free; you only pay the state filing fee itself.
A mid-year dissolution creates a short tax year. The final return covers the period from January 1 (or your fiscal year start) to the dissolution date, and is due by the normal deadline that follows the short year close. The FINAL RETURN box on Form 5472 and 1120 prevents the IRS from expecting another return next year.
Most states allow reinstatement of an administratively dissolved company within a window (typically two to five years), but a voluntary dissolution by Articles of Dissolution is generally final. The legal entity ceases to exist. If you want to operate again, the practical path is to form a new LLC — which can use the same name in most states if the dissolution is fully on record. The original EIN is permanent and cannot be reused.
Yes. If you are an active Monezzi subscriber on any plan, our dissolution service — Articles of Dissolution, final 5472 and 1120, EIN cancellation letter, state tax account closure, BOI final report at FinCEN — is included at no additional service charge. You only pay the state filing fee itself, because that money goes to the state, not to us.
