US Company Formation from Ecuador (2026): US LLC or C-Corp, the 5% Currency Outflow Tax (ISD), Worldwide Tax and Exporters' Miami Subsidiaries

Ecuador and the USA are bound together by trade. Ecuador exports roses, shrimp, bananas, cacao, tuna and coffee to the USA, and much of it lands in Miami. Ecuador also uses the US dollar as its currency. A growing number of Ecuadorian professionals and agencies in Quito, Guayaquil and Cuenca sell services to US clients. For exporters, a US company is often a distribution arm. For professionals, it is a way to contract and get paid like a US vendor. It can be formed from Ecuador entirely remotely.

Ecuador is not a territorial country like Panama: it taxes its residents on worldwide income. It also has a tax most countries do not, the Impuesto a la Salida de Divisas (ISD), a tax on money leaving Ecuador. Its general rate is 5%. ISD affects how you fund a US company, how you pay it, and even what happens when export proceeds stay abroad. This guide puts ISD at the centre, then compares US LLC formation and US C-Corp formation.

In short: Ecuadorians and residents of Ecuador can own 100% of a US LLC or C-Corporation, formed remotely. Ecuador taxes residents on worldwide income, at progressive rates for individuals and 25% for companies, with a credit for foreign tax. Transfers of money abroad generally pay ISD at 5%, subject to exemptions and the differentiated rates set for 2026 by Executive Decree 272. Proceeds from Ecuadorian exports that are not brought back to Ecuador can be presumed to have left the country and charged ISD, which matters for exporters selling through a US subsidiary. There is no US–Ecuador income tax treaty, so US corporate dividends to Ecuador carry 30% withholding. Low-taxed foreign entities can fall under Ecuador's preferential-regime rules. With UCB, a Wyoming LLC with EIN is $249, a Florida LLC with EIN is $299 and a Delaware corporation with EIN is $358, all-in.

Who can form a US company from Ecuador

US states set no nationality or residence requirement for owners, managers or directors. An Ecuadorian citizen, a foreigner living in Ecuador, or an Ecuadorian company (a compañía limitada or sociedad anónima, or an S.A.S.) can own a US company outright, with an individual owner as sole manager or director. No US visa, SSN or US address is needed, and no trip. The company needs a registered agent in its state, which is included for the first year in every UCB formation (see registered agent explained), and an EIN from the IRS, which needs no SSN or ITIN (see EIN for non-residents).

For identity, use a passport. The cédula alone is not accepted by US banks. For proof of address, a recent electricity or internet bill, or a bank statement, translated. If an Ecuadorian company will own the US company, have the following ready:

• its RUC (Registro Único de Contribuyentes);
• its certificate from the Superintendencia de Compañías;
• its shareholder list.

The ISD: Ecuador's tax on money leaving the country

ISD applies to transfers, payments and withdrawals of money from Ecuador to abroad, whether by bank transfer, cheque or card. The general rate has been 5% since April 2024. For 2026, Executive Decree 272 of 30 December 2025 set differentiated rates for certain transactions. Check the rate that applies to yours with your bank or accountant, along with the exemptions:

• some imports of capital goods and raw materials;
• certain payments of dividends and loans under specific conditions;
• a small annual exempt amount for individuals' card spending abroad.

For a founder or exporter with a US company, ISD comes up in four places.

Funding the company. Capital you transfer from Ecuador to the new US company's bank account is money leaving Ecuador, so expect ISD at the applicable rate. For a small company the amount is modest: 5% of US$2,000 is US$100. But build it into the plan.

Paying the US company. An Ecuadorian company that buys services or goods from its own US company pays ISD on the payments abroad, unless an exemption applies.

Export proceeds kept abroad. Ecuador presumes that money from exports of Ecuadorian goods and services has left the country, and charges ISD on it, if the export payments are not brought back into Ecuador within the legal period. This is aimed squarely at structures where an Ecuadorian exporter sells to its own US subsidiary and leaves the profit in the USA. Credits and exemptions can reduce the effect, but the presumption must be planned for.

Money coming back. ISD does not apply to money entering Ecuador. Distributions from a US company to an Ecuadorian owner do not pay ISD on arrival.

How Ecuador taxes a US company and its owner

Ecuador taxes resident individuals and companies on their worldwide income. Individuals pay progressive rates on taxable income. Companies pay 25%, with different rates in specific cases. Tax paid abroad on foreign income can be credited, up to the Ecuadorian tax on that income.

For an Ecuadorian resident who owns a US company:

• Dividends and distributions from the US company are foreign income, taxed in Ecuador with a credit for any US withholding.
• Work you perform in Ecuador is Ecuadorian income, whichever company invoices it.
• Preferential regimes. Ecuador's tax rules single out tax havens and "regímenes fiscales preferentes", meaning jurisdictions or regimes where the effective tax is well below Ecuador's. Payments to entities in such regimes can face higher withholding and closer transfer pricing review. Shareholdings in them must be reported carefully, including in the shareholder annex (anexo de accionistas) that Ecuadorian companies file. A disregarded US LLC that pays no US tax can be viewed this way, while a US C-Corporation paying 21% federal tax is less likely to be.

Your Ecuadorian accountant should review your structure against the SRI's current rules before you start invoicing through it.

US LLC formation from Ecuador

The US side

A single-member LLC owned by a non-resident is disregarded for US federal income tax. With no US office, US employees or US agents who conclude contracts, its income is generally not effectively connected with a US trade or business, so no federal income tax is due (see effectively connected income explained). Distributions to the owner are not US dividends, so no 30% withholding applies. The LLC files Form 5472 with a pro forma Form 1120 every year, and missing it carries a $25,000 penalty (see Form 5472 explained).

A Quito example

This is an illustrative example, not a client case. Ecuador uses the dollar, so there is no conversion.

Andrés is a data engineer in Quito whose clients are US health-tech companies. He forms a Wyoming LLC, funds it with US$1,500 from his Ecuadorian account (paying ISD at the applicable rate), and opens a US business account. The LLC invoices US$110,000 a year. After software costs, its profit is US$100,000.

In the USA, the LLC files Form 5472 and a pro forma 1120 and owes no federal income tax.

In Ecuador, his accountant reports the income as his own. The work is performed in Ecuador, and the LLC is a transparent conduit for his professional services. The income is taxed at Ecuador's progressive rates. Moving money from the LLC's US account to his Ecuadorian account is an inflow, so no ISD applies.

What the LLC changed for him was practical: his US clients now pay a US vendor, by ACH, on time.

US C-Corp formation from Ecuador

The US side

A C-Corporation pays 21% federal tax on its profits, plus state income tax where it does business (5.5% in Florida). It files Form 1120 and Form 5472 every year (see the 21% corporate tax explained and the C-Corp guide for non-residents). With no treaty, dividends, royalties and related-party interest paid to Ecuador are withheld at 30%.

Exporters' Miami subsidiaries

The most important C-Corporation use for Ecuador is the US import and distribution subsidiary of an Ecuadorian exporter. Take an illustrative case: a rose farm in Cayambe forms a Florida corporation. The subsidiary imports its flowers through Miami International Airport and sells to wholesalers, supermarkets and florists across the USA, especially before Valentine's Day and Mother's Day. It is the importer of record, meets US agricultural inspection rules, employs a sales team in Doral, and pays US tax on its own margin.

Three Ecuadorian rules then shape the pricing and cash flows between farm and subsidiary:

• Transfer pricing. The farm's sales to its US subsidiary must be at arm's length, documented under Ecuadorian and US rules. The farm earns the farming margin in Ecuador. The subsidiary earns a distribution margin in the USA.
• The ISD presumption. The farm's export proceeds, meaning what the subsidiary pays it for the flowers, must return to Ecuador within the legal period, or ISD is presumed. Paying the farm promptly, into its Ecuadorian account, keeps this clean.
• Dividends. Profits the subsidiary pays to the Ecuadorian parent are withheld at 30% in the USA, so most such subsidiaries reinvest in US distribution rather than paying dividends.

The same structure works for shrimp, cacao, coffee and tuna exporters. A disregarded LLC would be the wrong choice here, because it would make the Ecuadorian exporter itself the US taxpayer on the distribution business. See US subsidiary for a foreign company.

A corporation is also right for start-ups raising US investment (see raising US investment as a foreign founder).

Which state

• Wyoming or New Mexico for a service business run from Ecuador.
• Florida for anything with a Miami presence. That covers most Ecuadorian exporters and importers (see Florida LLC for non-residents).
• New York or New Jersey for businesses serving the large Ecuadorian community in Queens and northern New Jersey.
• Delaware for a corporation raising money.

See best state for non-residents and the state selector.

What it costs

State fees and the first-year registered agent are included. A US business address with your own suite number is $60 a year. ISD on transfers from Ecuador is separate. See what a US LLC costs every year.

Banking and payments

Residents of Ecuador are generally accepted by US banks and fintechs for remote business accounts. What gets applications through:

• A specific business description.
• An English website.
• Clear ownership documents for any Ecuadorian company in the chain.
• A US business address with your own suite number.

Because both countries use the dollar, there is no exchange risk. The practical cost is ISD on money going out, so plan transfers to Ecuador as inflows, which pay no ISD, and keep outflows to what the US company really needs. See US business bank accounts for non-residents, why banks reject non-resident applications and Stripe for non-residents.

Common mistakes

• Forgetting ISD when funding or paying the US company.
• Leaving export proceeds in a US subsidiary without planning for the ISD presumption.
• Assuming foreign income is not taxed in Ecuador. Ecuador taxes residents on worldwide income.
• Ignoring Ecuador's preferential-regime rules for a low-taxed LLC.
• Using a disregarded LLC for an exporter's US distribution business, which makes the exporter the US taxpayer.
• Skipping Form 5472 because the LLC owed no US tax.

Frequently asked questions

Can an Ecuadorian citizen own 100% of a US company? Yes, without visiting the USA or holding a US visa.

Do I pay ISD to fund my US company? Generally yes. Transfers abroad pay ISD at the applicable rate (5% general rate, with differentiated rates set for 2026), unless an exemption applies.

Is there a US–Ecuador tax treaty? No income tax treaty. US dividends, royalties and related-party interest paid to Ecuador are withheld at 30%.

Does Ecuador tax income from my US LLC? Yes. Ecuador taxes residents on worldwide income, with a credit for foreign tax. Income for work you do in Ecuador is Ecuadorian income in any case.

Will my US LLC pay US tax? Usually not, with no US office, staff or agents. It files Form 5472 and a pro forma 1120 every year.

Do I need an ITIN? Not to form the company or obtain its EIN. See what is an ITIN and who needs one.
