US LLC Annual Compliance for Foreign Owners: Full 2026 Checklist

Foreign founders often assume a US LLC with no employees and no US office has nothing to do each year. That is wrong, and the gap is expensive. The list below is the full set of recurring obligations for a typical single-member, foreign-owned US LLC, ranked by consequence. Master the first item and you have handled 90% of the risk.

The rest of this page works through each item — what it is, when it is due, and what happens if you skip it.

Of everything on the checklist, Form 5472 is the filing that can genuinely cost you tens of thousands of dollars. The IRS treats a foreign-owned single-member LLC as a corporation for this one reporting purpose under IRC §6038A (since 2017), and requires it to disclose every transaction with its foreign owner. The penalty for failing to file — or filing late or incomplete — is $25,000 per form, per year, under §6038A(d). The /form-5472-penalty/ guide covers exactly how that penalty works and compounds.

The trap is that the trigger is a transaction, not income. When you wired money to fund the LLC or paid its state fee from your own pocket, you created a reportable transaction. That is why a dormant, zero-revenue LLC still has to file. The filing itself is a pro forma Form 1120(a shell return) with Form 5472 attached, mailed to P.O. Box 149342, Austin, TX 78714-9342 or faxed to 855-887-7737 — it cannot be e-filed.

The April 15 deadline and the extension

Form 5472 is due April 15 for the prior calendar year. If you need more time, file Form 7004 by April 15 to extend the filing deadline to October 15. The extension moves only the filing date — for a disregarded entity there is no tax to pay, so there is nothing else to extend.

A registered agent is the person or company designated to receive legal and state mail on the LLC’s behalf at a physical in-state address. Because a non-resident founder has no US address, a commercial registered agent is mandatory. The service is inexpensive — typically $50–$150 per year — but it is not optional, and it renews every year on the anniversary of when the LLC was formed.

If the registered agent lapses, the state can mark the LLC as not in good standing and, after a grace period, administratively dissolveit. A dissolved LLC loses liability protection and can lose its name. Reinstating it costs more than simply keeping the agent current. Set a calendar reminder for the renewal, and keep the agent’s contact information current so you actually receive forwarded state notices.

State-level obligations vary widely, which is one reason founders pick states like Wyoming or New Mexico for low ongoing cost. There is no federal annual report for an LLC — this layer is purely a state matter, and the rules differ by where you formed.

These state fees are small and the penalties are mostly late fees, but ignoring them long enough leads to administrative dissolution. Keep them on the same annual calendar as your registered agent renewal, since both are state-level and often fall near the formation anniversary.

For most of 2024, a BOI report to FinCEN sat near the top of every LLC compliance checklist. That changed in 2025. FinCEN’s interim final rule, effective March 21, 2025, narrowed the definition of a “reporting company” to foreign-formed entities only. A US LLC is a domestic entity — defined by where it was created, not who owns it — so a foreign-owned Wyoming or Delaware LLC is now exempt from BOI. The /beneficial-ownership-information/ guide explains the rule and the rare exceptions in full.

One warning: the BOI exemption does not reduce your Form 5472 obligation by one cent. They are separate filings to separate agencies. Several founders stopped filing everything after hearing “US LLCs no longer file with FinCEN” — and walked straight into the $25,000 Form 5472 penalty. See /boi-vs-form-5472/ for a side-by-side comparison of the two.

This is the most fact-specific item on the checklist, and it is separate from the LLC’s Form 5472 obligation. A foreign-owned single-member LLC is a disregarded entity, so its activity flows up to the owner. Whether the owner owes US income tax — and therefore must file Form 1040-NR — depends on whether they have income that is effectively connected with a US trade or business (ECI) or other US-source taxable income.

Many non-resident e-commerce and service founders, with no US office, employees, or dependent agents, conclude they have no ECI and therefore no 1040-NR filing requirement. But this is a genuine tax-law judgment that turns on your specific activities, and it is the one item on this page where you should confirm with a qualified tax professional rather than assume. Note that form5472.tax does not represent clients before the IRS and does not provide personal income-tax advice — our service is the Form 5472 information return and its pro forma 1120.

Putting it all on one calendar removes the guesswork. For a calendar-year, foreign-owned US LLC, the year looks like this:

The single date you cannot miss is April 15 (or October 15 with an extension). Everything else carries modest late fees; Form 5472 carries $25,000. The /form-7004/ extension is the safety valve if April 15 is approaching and your records are not ready — file it on time and you buy six more months without penalty.

A foreign-owned single-member LLC is a disregarded entity, which normally files no corporate return at all. But Form 5472 has to ride on a Form 1120, so the IRS asks disregarded entities to submit a stripped-down or “pro forma” 1120 purely as a cover page. You are not electing corporate taxation and you are not reporting profit — you are providing the IRS with the envelope that Form 5472 lives inside. The /pro-forma-1120/ guide walks through every box.

What you actually fill in

Only the entity-identifying portion at the top of page 1 gets completed: the LLC’s name, address, EIN, and date of formation. Per the IRS instructions you write “Foreign-owned U.S. DE” across the top margin so the agency knows it is a disregarded-entity filing and not a real corporate return. Every income, deduction, and tax line below is left empty, because a disregarded entity computes no corporate tax. Form 5472 is then physically attached behind it.

Because there is no tax, there is nothing to e-file and nothing to pay. The whole package is mailed to P.O. Box 149342, Austin, TX 78714-9342, or faxed to 855-887-7737 — a foreign-owned disregarded entity cannot e-file this return.

Every Form 5472 and pro forma 1120 needs an Employer Identification Number (EIN) in the entity-identifying block, so getting one is the prerequisite to the entire annual filing. The good news for foreign founders is that you do notneed a US Social Security Number or ITIN to obtain an EIN for your LLC. On line 7b of Form SS-4 you write “Foreign” where it asks for the responsible party’s SSN/ITIN.

Why fax or mail, not online

The IRS online EIN assistant requires the responsible party to have an SSN or ITIN, so most non-residents cannot use it. Instead you complete Form SS-4 and submit it by fax or mail. Faxed applications are the fastest route for foreigners, normally producing an EIN in roughly four business days; mailed applications can take several weeks. Keep the CP575 EIN confirmation letter — you will reference that EIN on every annual filing for the life of the LLC.

Once the EIN is issued, the annual cycle begins: you use it on Form 5472, the pro forma 1120, your registered agent records, and any state report. You only apply for the EIN once.

Nothing in IRC §6038A or the Form 5472 instructions forces a foreign-owned LLC to open a US bank account. You can run an LLC through a payment processor, a foreign account, or a fintech business account and still file Form 5472 correctly. So strictly speaking, a bank account is a business convenience, not a compliance obligation.

Where it matters is evidence. Form 5472 reports the dollar value of every reportable transaction between the LLC and its foreign owner — capital contributions in, distributions out, loans, reimbursements, and intercompany payments. A dedicated US business account produces a clean ledger of exactly those flows, separated from your personal finances. When you fund the LLC by wire into its own account, that single line on a bank statement substantiates the contribution that triggers the filing in the first place.

Mixing personal and business money

The opposite scenario — paying the LLC’s state fee from your personal card, then taking money out informally — still creates reportable transactions, but it leaves you reconstructing amounts from scattered sources at filing time. That is slower, more error-prone, and weaker if the IRS ever asks for support. A separate account is the simplest way to keep the records that §6038A expects you to maintain (covered in the records section below). It also reinforces the liability separation that is the whole point of forming an LLC.

Form 5472 is built on a recordkeeping duty, not just a filing duty. Under IRC §6038A(a), a reporting corporation — which includes a foreign-owned disregarded LLC — must maintain recordssufficient to establish the accuracy of every reportable transaction it discloses. The penalty for failing to keep those records is a separate $25,000 under §6038A(d), independent of the $25,000 for failing to file the form itself. So a single year of total non-compliance can carry $50,000 in exposure.

The records to keep

You do not need a formal accounting system, but you do need a defensible paper trail. At minimum, keep the documents below for each tax year, and retain them as long as they may be relevant to the IRS — which, because the limitations period never starts while Form 5472 is unfiled, effectively means indefinitely until a return is on file.

Keeping these in one folder per year turns the annual Form 5472 into a 20-minute data-entry job rather than a forensic reconstruction. It is also your protection if the IRS ever questions a figure.

Founders frequently conflate “filing my LLC taxes” into one task, but a US LLC answers to two completely different authorities. Confusing them is how compliance gaps form — paying the $300 Delaware franchise tax does nothing for your Form 5472, and vice versa.

Why both matter

The federal layer is where the catastrophic money is: the $25,000 Form 5472 penalty has no cap and no statute of limitations, so it is the line you guard first. The state layer is cheaper to miss in dollar terms, but missing it long enough triggers administrative dissolution, which collapses your liability protection and can cost more to reverse than the original fee. A complete annual routine touches both: file Form 5472 by April 15, then renew the agent and file the state report around the formation anniversary.

Because Form 5472 has no statute of limitations until it is filed, an unfiled year never ages out — the IRS can assess the $25,000 penalty for a year you skipped a decade ago. And the penalty is per form, per year, with no cap, so the exposure scales linearly with the number of years missed.

How catch-up filing works

You cannot fix missed years by e-filing — disregarded entities never could. You prepare a separate Form 5472 + pro forma 1120 for each delinquent year and mail them to P.O. Box 149342, Austin, TX 78714-9342, or fax to 855-887-7737, ideally with a reasonable-cause statementexplaining why the filings were late. Reasonable cause can reduce or remove the penalty, but form5472.tax does not represent clients before the IRS; we prepare the delinquent returns and you submit them. The full procedure, including how to frame reasonable cause, is in the /form-5472-catch-up-filing/ guide.
