How to close a US LLC properly: IRS, EIN, bank and state

Close the state file, final IRS returns, EIN, bank accounts and records in the right order, with or without debts, so the LLC is genuinely clean.

A clean LLC dissolution runs 30 to 60 days and requires filing a final Form 1120 + 5472 marked as final return; skipping that step turns the LLC into a 25,000-dollar-per-year penalty accumulator.

Closing an LLC properly is as important as opening it. Most LLC content out there talks about how to form one, how to choose the state, how to open Mercury or Wise Business... but almost no one explains how to shut it down correctly. And yet a poorly dissolved LLC keeps generating obligations, penalties, fees and, in the worst case, a US tax shadow that can chase you for years. Exentax reviews the case before money, signatures or provider replies move forward.

This guide tells the real, complete process to dissolve and close your US LLC: when it makes sense, how to sequence the closure state by state, which final returns the <a href="https://www.irs.gov" target="_blank" rel="noopener">IRS</a> expects, what happens to your EIN, how to review BOI/FinCEN scope, how to cancel your bank accounts and why there is a strict order that should not be altered. If you are no longer operating your LLC and want to forget about it without surprises three years from now, this is the path.

Why formally close an LLC instead of "letting it die"

The classic fantasy of the LLC owner who has had enough is: "if I don't use it, I'll just leave it and the obligations will fade by themselves". It does not work that way. An LLC, while active or "delinquent" in its state register, keeps generating:

State annual report fees (USD 50 to 800 depending on state).
Franchise tax in Delaware (USD 300/year) and California (USD 800/year), among others.
Registered Agent fees annually (USD 50-150).
Form 5472 + 1120 pro forma before the IRS if the LLC has a single foreign owner, with the USD 25,000 penalty per unfiled form (Internal Revenue Code §6038A(d)).
BOI Report (<a href="https://www.fincen.gov" target="_blank" rel="noopener">FinCEN</a>) if your LLC remains within scope under the rules in force.
Possible bank account fees on Mercury, Wise Business, Relay or Slash.

If the LLC drifts into delinquent or administratively dissolved status due to unpaid annual reports, that does not exempt you from IRS obligations or accrued penalties. It only complicates your life when you eventually try to close properly or, worse, when you want to form another LLC years later and discover that you appear as the owner of an entity with accumulated penalties. The best strategy by far is a clean, formal closure in the right order. With Exentax, the deadline is tied to a responsible person, a record and a practical action.

Before you start: closure only happens when you are sure

Not every "I want to close" is real. Before starting, check that closure makes sense against the alternatives:

Pause operations temporarily, keeping the LLC alive but with zero activity, filing 5472 + 1120 with zeros and the BOI report when applicable. This is reasonable if you think you might use it again within two years.
Change structure (single-member to multi-member, or form a new entity and transfer contracts) if what changes is the business model, not the will to continue.
Move state through domestication or conversion if what weighs on you are taxes or reporting in your current state.

If after reviewing these options you still want to close, this is the procedure. Each case is individual, so review yours with an advisor before executing.

Overview: order matters

Closing an LLC is made up of seven blocks to be executed in this order. Skipping one or inverting the order usually leads to unnecessary costs or windows in which the LLC keeps generating obligations while you are no longer managing it:

Formal decision to dissolve (internal).
Operational wind-down (clients, contracts, debts, assets).
Closing of bank accounts and payment gateways.
Filing of final returns with the IRS (Form 1120 + 5472 marked Final return).
State dissolution (Articles of Dissolution or Certificate of Cancellation).
EIN closure with the IRS and final BOI/FinCEN scope review where applicable.
Cancellation of the Registered Agent and personal document archive.

Let us walk through each block with the detail that actually matters.

The closure sequence that prevents loose ends

1. Internal decision and Operating Agreement

Even if your LLC is single-member and you are the sole owner, the formal decision to dissolve must be documented. A well-drafted operating agreement requires it explicitly:

Resolution to dissolve: an internal document where the sole member decides to dissolve the LLC, with an effective date.
If the LLC is multi-member, a vote according to the percentage required by the operating agreement is needed (typically unanimity or qualified majority).

This document is not filed with the IRS or with the state, but it is the internal proof that the decision exists and that the closure is being executed in good faith. If anyone later asks when you stopped operating the LLC, that date is the one that counts.

2. Operational wind-down: clients, debts and assets

Before touching anything with the IRS or the state, the LLC must be emptied:

Closing of contracts with clients and vendors. Notify the cessation of activity. Issue final invoices. Collect what is pending.
Cancellation of subscriptions (Stripe, PayPal, SaaS tools, domains billed to the LLC, hosting).
Payment of pending debts (state taxes, Registered Agent, invoices, royalties, fees).
Distribution of remaining assets to the member (transfer the cash from the LLC account to your personal account). In a single-member LLC taxed as a disregarded entity, this distribution is not a taxable event for the IRS, but it must be documented as a member draw.
Bookkeeping retention (issued and received invoices, bank statements, vouchers) for at least seven years. This is the reasonable horizon for audits, interest and possible information requests.

Once the LLC is empty and free of live contracts, we can move on to the bank closure.

3. Closing bank accounts and payment gateways

Bank closure is where most mistakes happen. The practical rule:

Move all cash to a personal account of the member before requesting closure.
Wait for confirmed closure before filing the state dissolution. If you file the state dissolution and the bank discovers the entity no longer exists legally, it usually freezes pending movements.
Download every statement (at least seven years back) before closing. Once closed, recovering them can be impossible or expensive.
Cancel Stripe, PayPal and gateways linked to the LLC and download the transaction history.

4. Final returns with the IRS

This is where many closures break. The LLC, before dying, has to file its final IRS season, marking the forms as Final return:

Form 1120 + Form 5472 (Final) if your LLC is single-member with a foreign owner. The "Final return" box on Form 1120 must be ticked and the Form 5472 reportable information must include the final cash distribution to the member.
Form 1065 (Final) if your LLC was multi-member taxed as a partnership.
Form 1120 or 1120-S (Final) if you elected C-corp or S-corp taxation.
Form 966 (Corporate Dissolution or Liquidation) within the 30 days following the dissolution resolution, if the LLC was taxed as a corporation.
Form 941 / 940 final if you had employees.
Any pending information returns (1099, W-2, 8804/8805 if applicable).

The key date is: file the final returns before requesting the EIN closure. If you ask for EIN closure without having filed the final returns, the IRS will not close the EIN and may, even worse, generate a non-filer notice the following year.

If you have been carrying the LLC for years and have accumulated 5472 backlogs, the right move is to clean up before closing, not close to bury the issue. The detail of the specific risk is in the <a href="/en/blog/not-filing-form-5472-irs-penalties-and-how-to-fix-it">Form 5472 penalty guide</a>. Closing an LLC with pending 5472s does not extinguish accrued penalties; it only freezes them and the IRS keeps them against you as the individual associated with the EIN. The Exentax file stays aligned: facts first, documents second, response after that.

5. State dissolution:

Articles of Dissolution or Certificate of Cancellation

With cash distributed, accounts closed and final returns filed, we move on to the state closure. The exact name of the document depends on the state:

Wyoming: Articles of Dissolution with the Wyoming Secretary of State. Before filing them you must be current on the annual report and the license tax. Typical cost: USD 60.
New Mexico: Articles of Dissolution with the New Mexico Secretary of State. The LLC must be up to date with any applicable state tax. Typical cost: USD 25.
Delaware: Certificate of Cancellation with the Delaware Division of Corporations. You must pay the outstanding franchise tax and the franchise tax for the closure year before cancelling. Cancellation cost: USD 200; the franchise tax (USD 300/year) is added on top.
Florida: Articles of Dissolution with the Florida Division of Corporations.
California: if there was nexus in California, you must pay the USD 800 minimum franchise tax for the closure year plus file final Form 568.
Other states: each has its own form and fees; the logic is the same.

An important detail: if your LLC is registered as a foreign LLC in other states (because you did foreign qualification to sell in California, New York, Washington, etc.), before closing in the home state you must cancel each foreign registration. Otherwise, those states will keep charging annual reports and franchise taxes for years.

6. EIN closure and final BOI/FinCEN scope review

Once the LLC no longer exists legally (state dissolved + final returns filed), the last step with the IRS is to close the EIN. Technically, the IRS does not "delete" an EIN: it marks it as inactive. To do so, a signed letter to the Internal Revenue Service is sent identifying the entity by legal name, EIN, address and reason for closure, attaching a copy of the original Notice CP-575 or, failing that, the EIN assignment data.

In parallel, the BOI/FinCEN scope must be reviewed. After FinCEN's March 2025 interim final rule, a US-formed LLC is generally out of BOI reporting, while certain foreign entities registered to do business in a US state may remain in scope. If your entity is in scope, update the report according to FinCEN's current deadlines; if it is out of scope, archive a dated memo explaining why no BOI filing is due at closure.

If you have your own ITIN, or if there are partners with ITINs associated with the LLC, those ITINs are not "closed" with the LLC: they remain valid for your personal US activity as long as you use them periodically (see <a href="/en/blog/itin-for-non-residents-w-7-caa-and-real-uses">ITIN guide</a>).

7. Registered Agent, domains and personal archive

To close the loop:

Cancel the Registered Agent: notify in writing and ask for cancellation confirmation. If your Registered Agent renews by default each year, this is what avoids a surprise invoice next year.
Cancel domains and services billed to the LLC name.
Archive the final documentation in a safe place: original operating agreement, articles of organization, sealed articles of dissolution, EIN confirmation, copy of the final returns (1120, 5472, 1065, 966), bank statements, closed contracts. Minimum seven years.

That is when the LLC is clinically closed.

Typical mistakes we see when closing an LLC

At Exentax we have seen closures executed backwards dozens of times. The six most expensive mistakes:

Closing the bank before filing the final 5472. Documenting the last distribution becomes hard afterwards.
Filing state dissolution without paying the pending franchise tax (Delaware and California are the strictest).
Forgetting to cancel foreign qualifications in other states.
Not ticking Final return on the 1120 / 1065. The IRS keeps expecting a return next year.
Not reviewing BOI/FinCEN scope when regulations or ownership facts change.
Not retaining bank statements downloaded before closure.

Each of these mistakes translates into invoices, penalties or notices months or years later.

Coordinate state, tax and banking closure

Our LLC closure process follows exactly the seven steps in this guide. You give us the context (state, formation year, banking situation, returns filed, possible delays), we design the closure order, execute the final returns, coordinate with your Registered Agent and your banks, file the state dissolution, close the EIN and, where applicable, complete the BOI/FinCEN scope review or update. If you have been carrying late 5472s for years and need to clean up before closing, we do it as a prior phase of the closure to avoid dragging exposure forward.

Closing an LLC well is an act of tax hygiene: it tidies up your past and frees your future. It is worth doing in the right order and with someone who has done it hundreds of times.

Closing an LLC properly is part of compliance, not an afterthought. The file should show final state filings, bank wind-down, tax obligations, distributions, document retention and who remains responsible after operations stop.

Close state, tax and banking obligations in order

Closing the LLC reads more usefully when it's treated as a documented sequence — final filings, dissolution with the State, archiving of records — than as a sudden ending. The sequence doesn't change with the size of the LLC.

FinCEN and IRS reporting requirements moved recently; the current state is:

EIN and notice. Without an EIN you cannot file Form 5472. The IRS does not warn before imposing penalties; you find out when an EIN is flagged or a later filing is rejected. Exentax keeps the case readable for the client, the bank and the adviser at the same time.
