Form 5472 for Costa Rica Residents with a US LLC

A Costa Rica resident who owns a US single-member LLC files Form 5472 with a pro forma Form 1120 for every year the LLC had a reportable transaction with them. No US-Costa Rica income tax treaty is in force. Costa Rica's territorial tax system changes nothing: the FTIN box takes your DIMEX or NITE, or "None".

Costa Rica draws remote founders for reasons unrelated to tax paperwork, and many work through a US LLC in Wyoming, Delaware or New Mexico. The LLC is there for the plumbing: Stripe, a US bank account, and clients who prefer a US entity.

Two features of the Costa Rican position change the mechanics of this filing compared with a UK or Indian owner. The first is territorial taxation, which leads owners to assume income earned through a foreign LLC is invisible everywhere, including to the IRS. The second is identification: Costa Rica issues foreigners two numbers, a DIMEX and a NITE, and which you hold — if either — decides the FTIN entry. Neither removes the obligation.

Do Costa Rica residents have to file Form 5472?

Yes, on the same terms as any non-US owner. Three conditions:

1. The LLC is a US disregarded entity — a single-member LLC that has not elected corporate treatment.
2. Its sole member is a foreign person: not a US citizen, green card holder or US tax resident.
3. During the tax year there was at least one reportable transaction between the LLC and its owner or another foreign related party.

Treasury Regulation § 1.6038A-1 catches you: for tax years beginning on or after 1 January 2017 and ending on or after 13 December 2017, a foreign-owned US disregarded entity is treated as a corporation separate from its owner solely for the § 6038A reporting rules.

A reportable transaction is value moving between you and your own LLC — contributions in, distributions out, loans either way, payments for goods or services. Customer revenue is not reportable: a Texas client's Stripe payment stays off the form, while moving USD 4,000 from the LLC's balance to your Banco Nacional account goes on it.

The IRS Instructions for Form 5472 state that a $25,000 penalty may apply for failure to file when due and in the prescribed manner, for a substantially incomplete form, or for failure to keep the required records — and that a substantially incomplete Form 5472 constitutes a failure to file. Not every small error triggers it, but "substantially incomplete" is the phrase that catches self-prepared packages.

Does the US-Costa Rica tax treaty change anything?

There is no treaty to do any changing. Costa Rica does not appear on the IRS list of United States income tax treaties, whose C section runs Canada, Chile, China, Cyprus and the Czech Republic — no Costa Rica entry there or anywhere else on the page.

Be precise about what that absence proves. That page points readers to Table 3 of the tax treaty tables for each treaty's general effective date, and the US Treasury publishes its own list of treaties in force; neither shows Costa Rica. So the silence establishes only that no treaty is in force between the two countries, not that a convention was never signed. We found no official US or Costa Rican source showing a signed US-Costa Rica convention awaiting ratification, so treat any such claim as unverified unless it points to an official text. Either way, a signed treaty never in force gives a taxpayer nothing.

The consequences are narrow. There is no permanent establishment article to lean on, so whether your income is effectively connected with a US trade or business is decided under US domestic law alone — usually a comfortable answer for work performed entirely in Costa Rica, but one standing on its own facts. There is no treaty-reduced rate on US-source passive income and no residence tie-breaker. Form 5472 is untouched either way: treaties allocate taxing rights over income, while this is an information return under IRC § 6038A.

What goes in the FTIN box with a DIMEX, a NITE or neither?

Whichever Costa Rican number your tax record shows — and "None" if you hold no tax number anywhere. If line 4b(1) carries no US identifying number, line 4b(2) needs a self-assigned reference ID that you reuse every year.

Costa Rica identifies taxpayers by the document they hold, not by one tax-only number for everybody. The Ministry of Hacienda's questions-and-answers document for TRIBU-CR, its tax platform, states that the identifier in its Oficina Virtual is the identification number: the cédula de identidad, the DIMEX (Documento de Identidad Migratorio para Extranjeros), the NITE (Número de Identificación Tributario Especial) or, for diplomats, the DIDI. It adds that a foreign individual registering in the Registro Tributario does so with a DIMEX or a NITE — ten digits for a NITE, eleven or twelve for a DIMEX. The DIMEX follows an approved immigration status; the NITE is what Hacienda assigns so someone without one can still meet tax obligations. Many short-stay owners hold neither.

The right-hand column is identical in every row on purpose: your immigration category and Costa Rican registration change two entries, not whether the form is due.

Do not invent a number, do not enter a company's identifier as your personal FTIN, and do not apply for a US ITIN merely to fill the box. Our FTIN and reference ID guide covers the format. For the Part II address, use your real Costa Rican address, not the registered agent's.

Does Costa Rican tax affect the US filing?

No. They are two systems with no switch between them. In outline, and only as context:

Costa Rica taxes on a territorial basis. Article 1 of the Ley del Impuesto sobre la Renta, Ley 7092 charges tax on income from Costa Rican sources, and leaves it to regulation to decide who is domiciled in the country. Hacienda's published legal basis for fiscal-residency certificates points to article 10 of the Reglamento a la Ley del Impuesto sobre la Renta, Decreto 43198-H, with resolution DGT-R-065-2018 as amended in 2023; Hacienda's requirements sheet for that certificate, updated May 2023, states that a natural person must have stayed in the country, continuously or discontinuously, more than 183 days in the fiscal period certified. The law has been amended repeatedly, so read the consolidated text or ask a Costa Rican contador.

How Costa Rica treats profits you take out of a US LLC is a Costa Rican question we do not answer. The US side is narrower: crossing 183 days creates no US filing obligation, staying under it removes none, and a sociedad anónima or S.R.L. you own that transacts with your LLC is a second related party with its own form.

The digital-nomad law. Costa Rica legislated for remote workers in Law 10008, which the Instituto Costarricense de Turismo calls the "Ley de Nómadas Digitales" in its July 2022 announcement of an information microsite for that audience. The stay's duration, renewal terms, income floor and insurance conditions sit in the law and its regulation, published by the Dirección General de Migración y Extranjería; that site returned a 403 error on every attempt we made to load it, so we treat those requirements as unverified here — read migracion.go.cr directly or ask a Costa Rican immigration lawyer. The category is an immigration permission: it does not create, remove or alter a Form 5472 obligation.

How does a Costa Rica-based owner actually file?

You cannot e-file this package, and consumer tax software will not prepare it.

1. Prepare the pro forma Form 1120 with "Foreign-owned U.S. DE" across the top of page 1. Only the LLC's name and address and items B and E are needed.
2. Prepare Form 5472 — Part I for the LLC, Part II for you with your Costa Rican address and your DIMEX, NITE or "None" plus a reference ID, Part III for the related party, Part IV for the monetary transactions.
3. Attach a Part V statement itemizing contributions, owner-paid expenses and distributions. Convert colón amounts at a reasonable rate for each transaction date, consistently applied, and state your basis.
4. Sign, then fax to 855-887-7737, or mail to Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.
5. Keep the timestamped fax receipt. It is transmission evidence, not IRS acceptance of the return.

For a calendar-year LLC the due date is generally April 15; Form 7004 extends it under the special instructions for a foreign-owned DE. Dates are in our deadline guide; customer receipts stay off the form — see customer payments and Form 5472.

Getting it filed from Costa Rica

No treaty, a DIMEX or a NITE or neither, colón conversion, sometimes a Costa Rican company as a second related party: routine once seen, and exactly what makes a package substantially incomplete. We prepare the pro forma Form 1120, Form 5472 and the Part V statement, have a qualified tax accountant review the package, fax it to the IRS Ogden PIN Unit and send you the receipt. Late years include a reasonable cause cover letter.

$149 Standard, 5 to 7 business days. $199 Express, within 3 business days. +$99 per additional past tax year. IRS fax delivery included, so you never hunt for a fax machine in San José.

We are not a CPA firm and do not give tax advice, US or Costa Rican. We prepare and submit the US information return.

Frequently asked questions

Do I have to file if Costa Rica does not tax my foreign income?

Yes. Form 5472 is an information return, not a tax return, and does not depend on tax being due anywhere. If your US single-member LLC had a reportable transaction with you, it is required and the $25,000 exposure applies.

Is there a US-Costa Rica tax treaty?

No income tax treaty is in force: Costa Rica is absent from the IRS treaty A-to-Z list, which covers treaties in force. We found no official source confirming a convention was ever signed, and one not in force gives you nothing to claim.

Can I use my DIMEX as my FTIN?

If your Registro Tributario record identifies you by your DIMEX, that is what your tax record shows, so it belongs in the box. With no Costa Rican registration, write "None" and add a reference ID.

Does the digital-nomad stay under Law 10008 change my US filing?

No. It is an immigration permission from the Dirección General de Migración y Extranjería. It does not create, remove or change a Form 5472 obligation, nor affect the FTIN box.

Are my Stripe payouts reportable transactions?

No. Payments from unrelated clients are customer revenue and stay off the form. Reported items are value moving between you and the LLC: contributions, distributions, loans either way, and LLC expenses you pay personally.

I split the year between Costa Rica and other countries. Which address goes in Part II?

Use the address where you actually are, not the LLC's US agent address. Our guide for digital nomads covers Part II with no single tax residence.

I have never filed and the LLC is four years old. What now?

File every outstanding year with a reasonable cause statement, ideally before the IRS writes to you. Each year is a separate filing with its own exposure; our late filing guide sets out the sequence.

Territorial taxation and a missing treaty are real features of life in Costa Rica, and neither reaches this filing. If value moved between you and your US LLC last year, the return is due. Start your filing — about 15 minutes — or read the FTIN and reference ID guide first.
