After You Form the LLC: Non-Resident Annual Compliance — Form 5472, Pro-Forma 1120, EIN & State Filings

Forming the LLC was the easy part. What formation agents mention too quietly is the annual filing that follows every foreign-owned single-member LLC: Form 5472, attached to a pro-forma Form 1120, with a $25,000 penalty for getting it wrong or not filing at all. This is the compliance guide non-residents actually need — October 2026 edition.

The Filing Everyone Misses: Form 5472 + Pro-Forma 1120

Here is the rule in one paragraph. A US LLC with a single foreign owner is usually a disregarded entity for federal income tax — but since 2017 it is treated as a corporation for reporting purposes, which means every year it must file Form 5472 (information return of a 25% foreign-owned US corporation) attached to a pro-forma Form 1120. The pro-forma return is mostly identification pages — name, address, EIN, a few lines — with the 5472 carrying the substance: the foreign owner’s details and the year’s reportable transactions between the LLC and its owner or related parties.

“Reportable” is broader than new founders expect. It includes money you put in (formation funding, capital contributions), money you took out (distributions, paying personal expenses), loans either way, rent or services between you and the company, and the formation-year costs themselves. A company that “did nothing” still typically has formation transactions to report. The filing is due with the corporate calendar — normally April 15 for calendar-year filers, with an automatic extension available to October 15 by filing Form 7004 — and, unusually for the IRS, this specific return is generally filed by mail or fax to a designated IRS processing address rather than through standard e-file when it is the company’s only filing. Confirm the current filing address in the Form 5472 instructions for your filing year; the IRS updates these details and this area is actively enforced.

And the penalty, because it is the reason this page exists: failure to file Form 5472 when due carries an IRS-stated penalty of $25,000, with additional penalties accruing if the failure continues after IRS notice. That figure — cited in the IRS’s own instructions — is per year, and it applies even when the LLC owes no tax and made no profit. If you formed through our guide to forming an LLC as a non-resident, this filing is the annual obligation that comes with the structure. It is not optional, and “my agent never mentioned it” has never been a defence.

This guide is general information as of October 2026, not tax advice. US tax rules for foreign owners are individual — verify your position with the current IRS instructions for Forms 5472 and 1120, or a qualified US CPA, before filing.

Step by Step: EIN First, Then the Annual Return

The annual cycle has a dependency chain, and the first link is the EIN. You need an Employer Identification Number to file anything, open banking properly, and identify the company on the 5472. Non-residents without an SSN or ITIN obtain one by filing Form SS-4 through the international route — historically by fax or mail to the IRS’s designated international processing, with the “foreign” entries completed per the SS-4 instructions (there is no online EIN application without a US taxpayer ID for the responsible party). Processing takes weeks, not days, so the EIN belongs in your formation month, not your filing month.

With the EIN in hand, the annual work itself follows a rhythm:

• Collect the year’s transactions. Every transfer between you (and related parties) and the LLC: dates, amounts, purpose. A dedicated company bank account makes this an export instead of an excavation — another reason the banking step below matters.
• Prepare the pro-forma 1120. Identification and the limited lines the instructions require for this filing posture, signed and dated as instructed.
• Complete Form 5472. Owner information, the reporting company’s details, and the transaction totals by category in Part V (and any other parts your situation triggers).
• File to the designated address by the deadline (or file Form 7004 first if you need the extension — the extension extends filing, never any payment obligation, and this posture usually has none).
• Keep proof. Retain the filed copies and mailing/fax confirmation with your company records; if the IRS ever asks, the burden of showing you filed is yours.

Most non-resident founders reasonably hand this to a US CPA or a filing service — the form is short, but the definitions (related party, reportable transaction) are where errors live. Whether you DIY or delegate, calendar it: the penalty regime does not distinguish between “forgot” and “refused”.

The State Layer: Annual Reports, Franchise Taxes and Your Registered Agent

Federal compliance is only half the calendar. Your state of formation imposes its own annual obligations, and they differ enough that “LLCs need an annual report” is dangerously vague. Orientation for the popular formation states — confirm your state’s current requirement and fee on its official site before relying on any line:

• Wyoming — an annual report tied to a license tax based on assets located in Wyoming (with a modest minimum), due on the first day of the formation anniversary month. Famously light, but not nothing.
• Delaware — LLCs pay a flat annual franchise tax (long set at $300), due June 1, regardless of activity or income. No annual report for LLCs, but the tax is unconditional.
• New Mexico — no annual report and no annual state fee for LLCs, one reason it appears in low-maintenance comparisons; the federal 5472 obligation applies in full regardless.
• Florida — an annual report due between January 1 and May 1, with a steep late fee after the deadline and administrative dissolution for companies that ignore it into the autumn.

Across all states sit two constants. Your registered agent must be maintained and renewed — let it lapse and you can miss lawfully-served notices and state reminders, sometimes until the company is dissolved. And good standing is a practical asset: banks, marketplaces and payment processors increasingly ask for a certificate of good standing or status check when you open or renew accounts, and a dissolved LLC behind your Amazon or Stripe account is a five-alarm operational fire. Amazon’s Brand Registry, for example, is far easier to build on a company whose paperwork is boringly perfect — see how the pieces connect in our Amazon Brand Registry guide.

Banking and Payments After Formation: What Providers Actually Ask For

Compliance and banking are the same project seen from two sides. When a non-resident founder applies for US business banking or payment processing — traditional banks, or the fintech routes (Mercury, Wise, Relay and similar) that most overseas founders realistically use — the document pack is predictable: articles of organization, EIN confirmation letter, operating agreement, passport for the owner, and increasingly proof of the company’s good standing and a US address story that makes sense (registered agent address alone is sometimes not enough for a trading address). Stripe and similar processors ask for the same spine: EIN, formation state, owner identity verification.

Two practical consequences follow. First, sequence formation correctly: LLC → EIN → bank account → marketplace and payment accounts, all in the company’s name and EIN, so your Form 5472 transaction records and your marketplace payouts reconcile without explanation. Running the business through a personal account is what turns a one-hour annual filing into a forensic reconstruction. Second, expect periodic re-verification: fintechs and marketplaces re-check identity and company status on cycles and on triggers (volume changes, address changes). A company that is dissolved, or an owner who cannot produce an EIN letter, fails those checks at the worst possible moment. Treat renewals and filings as account insurance, priced accordingly — and if you are adding brand protection to the structure, our US trademark registration service pairs naturally with the same paperwork discipline.

The Compliance Calendar: Every Deadline in One Place

Pin this sequence (calendar-year company; your state dates may add to it — verify each against the current official source for your filing year):

• January–March — close the prior year’s books; gather owner↔LLC transaction records; Florida annual report window open (Jan 1–May 1).
• April 15 — federal deadline: pro-forma Form 1120 + Form 5472 due (or Form 7004 filed for the automatic extension to October 15).
• June 1 — Delaware LLC franchise tax due.
• Anniversary month (Wyoming) — annual report/license tax due the first day of the formation month.
• October 15 — extended federal deadline: the 5472 filing must be in. There is no second extension.
• All year — registered agent active; address changes reported to state and IRS (Form 8822-B for responsible-party/address changes); good standing checked before banking or marketplace reviews.

One calendar habit separates calm founders from penalised ones: a single recurring reminder 60 days before each date, owned by a named human or a service — because every deadline above is fixed, published and unforgiving. The cost of the whole annual cycle, handled properly, is a rounding error next to the $25,000 it protects against.

Zero-Income Years, BOI and Multiple LLCs: The Edge Cases

Zero-income years. The 5472 obligation follows ownership and transactions, not profit. A dormant LLC with no sales but an owner who paid its registered-agent renewal from a personal card has reportable transactions. If a company truly had no reportable transactions and meets the narrow conditions in the instructions, confirm that position with a professional rather than assuming silence is safe — penalties attach to missing filings, and the IRS discovers foreign-owned LLCs through banking and marketplace data, not luck.

Beneficial ownership (BOI). The Corporate Transparency Act’s reporting regime changed significantly during 2025: FinCEN’s interim rule-making removed the BOI reporting requirement for US-formed (domestic) companies, leaving it focused on foreign reporting companies. As of October 2026, a domestic US LLC formed by a non-resident generally sits on the exempt side of that interim position — but this is precisely the kind of rule that is still moving through courts and rulemaking, so check FinCEN’s current guidance each year rather than relying on any guide, including this one.

Multiple LLCs. Each foreign-owned disregarded LLC files its own 5472 package; there is no consolidated shortcut. If you hold several companies (one per brand is a common pattern), the calendar above multiplies — one more argument for professional handling once the count passes one. And when a company is genuinely finished, dissolve it properly at the state and file the final-year return: an abandoned LLC keeps accruing obligations and penalties in the dark.

If this page just described your situation in the past tense — filings already missed — do not wait for an IRS notice to act; late-filed 5472s with reasonable-cause statements are a known remediation path and professionals handle them routinely. Our US LLC formation and compliance team can assess where your company stands, and a free audit is a reasonable first conversation.
