Change LLC maintenance provider without losing history or continuity

7 to 14 days and never touches the original formation date. How to migrate from your current Registered Agent, tax preparer or bookkeeper without creating compliance gaps, losing history or breaking your banking relationships. Orderly procedure in 7 steps.

Switching the maintenance provider of an LLC typically takes 7 to 14 days and never touches the original formation date, which stays untouched on the Secretary of State record.

Switching your LLC maintenance provider is one of the decisions that scares people most and has the fewest consequences when done right. The vast majority of LLC owners who come to Exentax wanting to switch share the same fear: "am I going to lose seniority?", "does anything reset?", "will the IRS notice?".

Short answer: no, no and almost no. Long answer is this guide.

What does NOT change when you switch providers

Before explaining how, let us pin down what stays intact. Switching maintenance providers does not touch:

The LLC itself. It is still the same legal entity registered in the same state, with the same name and same formation date. Your seniority is intact.
The EIN. The IRS-assigned tax number does not change except in very specific transformations.
The Articles of Organization. The founding document stays exactly as is.
The banking history. Mercury, Wise, Relay and similar require no action unless your Registered Agent or address shows up in the profile.
The tax history. Filings made with the IRS and FinCEN remain valid and credited to you.

What DOES change

Three things, all operational:

The Registered Agent, if your new provider offers a different RA than your current one.
The mailing address, if the previous provider's address was on file with the state or IRS.
The party responsible for filing forms in the next cycle: 5472, BOI, Annual Report, etc.

None of this affects the entity itself: these are service-provider changes, not changes in legal nature.

Step-by-step procedure

Step 1. Diagnose what is tied to the current provider

Before touching anything, identify what is in the current provider's hands:

Is it the Registered Agent on file with the state?
Is its address listed as mailing address on the EIN Confirmation Letter or IRS profile?
Does it hold credentials to the Secretary of State, FinCEN or IRS portals?
Does it have copies of your Operating Agreement, Articles, EIN letter and BOI confirmation?

Documenting this on a sheet before initiating the switch avoids surprises.

Step 2. Recover your documents

Before announcing the switch, make sure you hold:

Articles of Organization
EIN Confirmation Letter (CP 575) or 147C
Signed Operating Agreement
BOI Report confirmation
Most recent Annual Report or Franchise Tax filed
Copies of the most recent Forms 5472 + 1120 pro-forma

If the current provider refuses to hand them over, you have the legal right to obtain them. Push. There are administrative routes if needed (147C from IRS, certificate of good standing from the state, BOI confirmation from FinCEN).

Step 3. Designate the new Registered Agent

The RA change is filed via a Statement of Change of Registered Agent (or state equivalent) with the Secretary of State. Standard fee: 10-50 USD, processed in days. The new RA must have accepted you as a client before filing. Effective date is filing date; from that point, legal mail goes to the new RA.

Step 4. Update IRS mailing address if needed

If the previous provider's address is the LLC's IRS address, file Form 8822-B to update it. Simple one-page form.

Step 5. Update the BOI Report if anything changes

If the provider switch implies a change in LLC mailing address or any reported beneficiary information, you have 30 days to update BOI with FinCEN. Online and free.

Step 6. Inform banking and platforms (only if needed)

Mercury, Wise, Relay and similar do not need to know about the RA change unless your registered LLC address has changed. If it has, update each platform to avoid mismatches in their KYC reviews.

Step 7. Clean exit with the prior provider

Confirm in writing the service end date, request prorated refund if applicable, and save the email. This closes the cycle and prevents "automatic charges" for the next year.

How long it takes and how much it costs

A well-executed switch completes in 2-4 weeks and costs:

Statement of Change of RA: 10-50 USD per state
Form 8822-B: free
BOI update: free
New provider fees: per package contracted

No penalty, no reset, nothing "lost". The only thing lost is the inertia with the provider that no longer served you. Relax: at Exentax this is what we do every week, we close it before the letter ever lands in your inbox.

When NOT to switch (yet)

Two moments to wait:

Weeks before fiscal close, if the current provider is preparing your 5472 for the period. Finish that cycle and switch after.
With BOI or 5472 in remediation, if the current provider is handling it. Finish that file first.

In any other scenario, waiting "just in case" costs money and adds no security.

How we do it at Exentax

At Exentax we onboard switching clients every month. The process is exactly the one above. We handle the RA change, the 8822-B, the BOI update if needed, and start the next cycle without you losing a day of coverage.

If you have been thinking your current provider is not delivering and want to see if we fit, book a free initial session through our booking page. We tell you honestly whether to switch now, wait until close, or stay where you are.

Next steps

Now that you have the full context, the natural next step is to map it against your own situation: what fits, what doesn't, and where the nuances depend on your residency, your activity and your volume. A quick review of your specific case usually saves a lot of noise before taking any structural decision.

Banking and tax facts worth clarifying

Fintech and CRS information evolves; here is the current state:

How to read changing the LLC maintenance provider as a stable transition mapping rather than as a rupture

Changing the LLC maintenance provider reads more usefully when it's treated as a stable transition mapping between three handovers — Registered Agent, mailing address, document custody — than as a rupture with the previous setup. Each of the three handovers follows a documentable pattern that doesn't depend on the new provider chosen.

A short note in the LLC folder that records the date of each handover and the confirmation reference returns the transition into something the member can revisit in a few minutes whenever a tax adviser, a bank or a future provider asks for the timeline.

Before going further, put numbers on your case: the Exentax calculator compares, in under 2 minutes, your current tax bill with what you would carry running a US LLC properly declared in your country of residence.

Notes by provider

Mercury operates with several federally chartered partner banks and FDIC coverage via sweep network: mainly Choice Financial Group and Evolve Bank & Trust, with Column N.A. still in some legacy accounts. Mercury is not itself a bank; it is a fintech platform backed by those partner banks. If Mercury closes an account, the balance is typically returned by paper check mailed to the account holder's registered address, which can be a serious operational problem for non-residents; keep a secondary account (Relay, Wise Business, etc.) as contingency.
Wise ships two clearly different products: Wise Personal and Wise Business. For an LLC you must open Wise Business, not the personal account. Important CRS nuance: a Wise Business held by a US LLC sits outside CRS because the account holder is a US entity and the US is not a CRS participant; the USD side operates via Wise US Inc. (FATCA perimeter, not CRS). In contrast, a Wise Personal opened by an individual tax-resident in Spain or another CRS jurisdiction does trigger CRS reporting via Wise Europe SA (Belgium) on that individual. Opening Wise for your LLC does not bring you into CRS through the LLC; a separate Wise Personal in your own name as a CRS-resident individual does report.
Wallester (Estonia) is a European financial entity with an EMI/issuing-bank licence. Its European IBAN accounts are within the Common Reporting Standard (CRS) and therefore trigger automatic reporting to the tax administration of the holder's country of residence.
Payoneer operates through European entities (Payoneer Europe Ltd, Ireland) that are also in scope for CRS for clients resident in participating jurisdictions.
Revolut Business: when paired with a US LLC, it operates under Revolut Technologies Inc. with Lead Bank as its US banking partner. The account delivered is a US account (routing + account number); no European IBAN is issued to a US LLC. The European IBANs (Lithuanian, Belgian) belong to Revolut Bank UAB and are issued to European clients of the group. If you are offered a European IBAN tied to your LLC, confirm exactly which legal entity holds that account and which regime it reports under.
Zero tax: no LLC structure delivers "zero tax" if you live in a country with CFC/tax transparency or income attribution rules. What you achieve is no double taxation and correct reporting at residence, not elimination.

Legal & procedural facts

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

BOI / Corporate Transparency Act: your LLC is NOT required to file (a competitive advantage). After FinCEN's March 2025 interim final rule, the BOI Report obligation was narrowed to "foreign reporting companies" (entities formed OUTSIDE the US and registered to do business in a state). A US-formed LLC owned by a non-resident does NOT file the BOI Report: one fewer filing on your calendar, less paperwork, and a cleaner structure than ever. If your LLC was formed before March 2025 and you already filed BOI, keep the acknowledgement. The regulatory status can change again: we monitor FinCEN.gov on every filing and, if the obligation comes back, we handle it at no extra cost. Current status verifiable at fincen.gov/boi.
Form 5472 + pro-forma 1120. For a Single-Member LLC owned by a non-resident, the final regulations of Treas. Reg. §1.6038A-1 (in force since 2017) treat the LLC as a corporation for 5472 purposes. Procedure: pro-forma Form 1120 (header only: name, address, EIN, tax year) with Form 5472 attached. It is filed by certified mail or fax to the IRS Service Center in Ogden, Utah, not e-filed via standard MeF. Due date: April 15; extension via Form 7004 to October 15. Penalty: $25,000 per form per year, plus $25,000 per additional 30 days of non-filing after IRS notice.
Substantive Form 1120. Only applies if the LLC has filed a check-the-box election to C-Corp (Form 8832): it then pays 21 % federal corporate tax and files a substantive 1120. A standard disregarded LLC does not file a substantive 1120 and does not pay federal corporate tax.
EIN and notice. Without an EIN you cannot file 5472 or BOI. The IRS does not warn before imposing penalties; you find out when an EIN is flagged or a later filing is rejected. This is where Exentax steps in: we file the form, archive the receipt and, if the authority asks, your answer is already on the desk.

The operational truth about changing your LLC maintenance provider

Your LLC's seniority lives at the formation state and in IRS records, not in your current provider's dashboard. Switching providers is an administrative formality, not a refoundation. The confusion exists because some providers frame the change as traumatic to retain the client. These are the five pieces that matter, in order.

Registered agent. The only legally binding element at state level. Changed with a short form at the Secretary of State (Wyoming, New Mexico or Delaware: around USD 10-25). The change is immediate and the formation date is untouched.
Annual report and franchise tax. Deadlines are set by the state, not the provider. If your previous provider missed dates, the problem was operational, not structural. After the change, the new provider (or you directly) handles the next annual report on the same due date.
EIN and IRS records. The EIN is permanent and tied to the LLC, not the provider. The only thing that changes is the "responsible party" if you take that role; reported via Form 8822-B, no fee, no reset.
Bank account and business address. If the provider's address appeared on Mercury, update it to the new commercial address (or personal address if you decide so). Mercury applies this in 24-48 hours with a simple proof.
5472 and BOI. A provider change creates no extra Form 5472 obligation, but it is wise to include the address/responsible-party change in the next BOI report to FinCEN within the 30-day window provided by the rule.

What we are asked the most

Do I lose banking or credit history with the change? No. Mercury does not see the change except for the address part. Transactional history remains intact and account seniority stays.

Does the IRS flag the LLC as suspicious for an agent change? No. Registered agent changes are routine and thousands are processed weekly in each state. What does flag an LLC is failing to file 5472 or carrying years of unpaid annual reports - both unrelated to the provider change.

At Exentax we receive LLCs every week migrating providers and we leave agent, address, calendar and BOI notice in motion without the client writing a single email.

What does NOT change when you switch provider

Read this section as a checklist with teeth: each point flags a real failure mode we have seen in cross-border LLC files. Skip none of them - most reassessments and account closures we clean up later trace back to one of these items.

Step 3. Appoint the new Registered Agent

If it is not clean here, every downstream assumption becomes negotiable in front of the authority.

Step 4. Update the IRS mailing address if applicable

Most of the avoidable damage we see in this exact point comes from skipping the documentation step, not from the underlying tax logic.

Step 5. Update the BOI Report if anything changes

On the same topic

What if HMRC, the IRS or my local tax authority asks about my LLC?

It's the question every client raises in the first consultation, and the short answer is: your LLC isn't opaque, and a properly declared structure closes any inquiry in standard forms. Your tax authority can request the state Certificate of Formation (Wyoming, Delaware or New Mexico), the EIN issued by the IRS, the signed Operating Agreement, the Mercury or Wise statements for the year, the Form 5472 plus pro-forma 1120 you filed, and the bookkeeping that reconciles income, expenses and movements. If all of that exists and is delivered in order, the inquiry doesn't escalate.

What tax authorities do pursue, and rightly, is sham ownership (nominees, paper residency) and undeclared foreign accounts. A well-structured LLC is the opposite: you appear as beneficial owner in the BOI Report when applicable (verifiable at fincen.gov/boi), you sign the bank accounts and you declare the income where you actually live. The structure is registered with the state Secretary of State, with the IRS and, when European banks are involved, inside the CRS perimeter of the OECD standard.

The mistake that really sinks an inquiry isn't having an LLC; it's not attributing the income correctly in your domestic return, not declaring foreign accounts when the year-end balance exceeds the local threshold (€50,000 in Spain via Modelo 720; the equivalent FBAR / Form 8938 in the US for residents; T1135 in Canada), and not documenting related-party transactions between the member and the LLC. Those three fronts are worth closing before any request arrives, not after.

## What an LLC does NOT do

- It does not exempt you from tax in your country of residence. If you live in Spain, France, Germany or Portugal, you are taxed there on worldwide income. The LLC organises your US side (zero federal tax for non-resident SMLLC pass-through, absent Effectively Connected Income); it does not switch off your domestic taxation. The income tax is computed on the attributed profit, not on the dividends actually paid.

- It is not an offshore vehicle or a BEPS scheme. It is a US entity recognised by the IRS, registered in a specific state with physical address, registered agent and annual informational filings. Classic offshore jurisdictions (BVI, Belize, Seychelles) leave no public trace; an LLC leaves a trace in five different places.

- It does not protect you if you commingle funds. The pierce the corporate veil doctrine kicks in as soon as a judge sees the LLC and the member behaving as the same wallet: mixed accounts, personal expenses paid from the LLC, no signed Operating Agreement, no bookkeeping. Three suspicious transactions are enough.

- It does not save you social security contributions at home. If you are self-employed in Spain, France or Germany, your monthly social contribution remains identical. The LLC handles the trading side with international clients; your personal contribution is independent.

- It does not exempt you from declaring foreign accounts. Spain residents file Modelo 720 / 721; UK residents, the SA106; Portugal residents, the Anexo J of Modelo 3 IRS; Germany residents, the Anlage AUS. Those obligations belong to the individual, not to the LLC.

At Exentax we cover those five fronts every year alongside the US federal calendar (Form 5472, pro-forma 1120, FBAR, state Annual Report and BOI Report when applicable). The goal is that no inquiry finds a loose end and that the structure withstands a 5-to-7-year retroactive review.
