Santiago is the engine of Chile's tech economy, and a growing share of its founders, agencies, and freelancers now invoice US clients in dollars. Since the Chile-US tax treaty entered into force, a Wyoming LLC has become the cleanest way for a Santiago founder to run that US-facing business: $397 all-in, formed in about 24 hours, with treaty-backed tax relief built in.
Why Santiago founders form a Wyoming LLC
Santiago concentrates most of Chile's startup, SaaS, and freelance talent. The ecosystem that Start-Up Chile seeded in 2010 from the capital has matured into a dense network of software studios, fintech teams, design agencies, and independent developers, many of whom now earn more from US and European clients than from the domestic market. The constraint these founders hit is not talent or product. It is the plumbing between a Chilean person and a US-paying customer.
A US client paying a Chilean freelancer or agency usually wants to pay a US business, not wire pesos to a personal Banco de Chile or Santander account. Stripe, US-based SaaS billing, US marketplaces, and most US procurement systems expect a US entity with an EIN and a US bank account. Without one, Santiago founders get pushed onto slower, costlier rails: international wires that take days, PayPal with its conversion spread, or Global66 and Wise personal accounts that work but signal "individual contractor" rather than "company." A Wyoming LLC flips that perception. You become a US vendor that can be paid by ACH, issue clean USD invoices, and onboard to platforms that quietly exclude individuals.
Wyoming specifically is the default for non-residents for three reasons. There is no state income tax, so the LLC adds no Wyoming-level tax on top of your federal obligations. There is no state-level public member registry, so your name is not splashed across a searchable database. And the annual cost is among the lowest in the US. For a single-member, foreign-owned LLC that is taxed as a disregarded entity, this means the entity itself usually owes no US federal income tax on non-US-sourced services income, while still giving you the US footprint clients want.
The timing matters too. Chile is now one of a small group of Latin American countries with a comprehensive US income tax treaty in force, which changes the math on US-source dividends and royalties in a way that did not exist for Chilean founders a few years ago. For a Santiago founder weighing whether the US structure is worth it, the treaty removes a major downside that still applies to founders in most neighboring countries. A Bogota or Lima founder cannot claim reduced US withholding because Colombia and Peru have no comprehensive treaty with the US; a Santiago founder can. That single difference makes Chile one of the more attractive LATAM bases for a US-facing online business right now.
There is also a practical, currency-level reason. The Chilean peso is volatile, and a founder earning in dollars but holding everything in pesos absorbs that swing every month. With a US LLC and a USD account, you can hold a dollar balance, pay your US software and contractor costs directly in dollars, and convert to pesos only when you actually need local liquidity or when the rate is favorable. For a Santiago agency or SaaS team with meaningful USD revenue, that control over conversion timing is worth real money over a year.
Cost from Santiago
The package is $397 and the Wyoming state filing fee is already included. There is no separate government charge to budget for at formation. After year one, your recurring cost is the registered agent renewal plus the Wyoming annual report, which together land around $160 per year.
| Item | When | Cost (USD) |
|---|---|---|
| Wyoming LLC formation (state fee included) | One-time | $397 |
| Registered agent, year 1 | Included | $0 |
| EIN (Form SS-4) and banking introductions | Included | $0 |
| Wyoming annual report + registered agent renewal | Each year | ~$160 |
| ITIN application (optional add-on) | If needed | $297 |
The $397 covers the Wyoming Secretary of State formation filing, registered agent service for the first year, your EIN obtained via IRS Form SS-4, and introductions to banking partners. The ITIN is a separate $297 add-on and most Santiago founders running a services business through a disregarded LLC do not need one. You typically only need an ITIN if you have a US tax filing obligation in your own name, which is uncommon for a single-member LLC earning foreign-source services income. The Wyoming annual report fee is set by the Wyoming Secretary of State and is based on assets located in Wyoming, so for a typical online business it stays at the minimum.
Banking from Santiago
Realistically, your two strongest options from Santiago are Mercury and Wise Business, with Relay as a backup. Chile is not on the restricted-country lists for these providers, and Chilean documentation, a clean passport, a verifiable Santiago address, and a coherent business description, tends to clear review without the extended back-and-forth that founders from higher-risk jurisdictions face. In our experience Chilean profiles see Mercury approval that varies by profile and is not guaranteed, though it is strong for a non-resident market.
That said, 2025 brought real tightening across the fintech-banking space, and Santiago founders should apply prepared rather than assume automatic approval. Mercury no longer accepts a registered agent address as your principal business address, so use your real Santiago address. Mercury and similar providers now want to see a genuine business: a clear description of what you sell, who your US-facing customers are, and ideally some evidence of planned or existing operations. Brand-new entities with zero revenue and a vague description are the ones that get stuck in additional document requests or declined. Have your passport, proof of your Santiago address (a utility bill or bank statement works), your EIN confirmation, and your Wyoming formation documents ready before you start the application.
Wise Business is the pragmatic complement, not just a fallback. It gives your LLC USD account and routing details plus local details in several currencies, and its conversion into Chilean pesos is transparent and cheap relative to traditional bank wires. A common Santiago setup is Mercury as the primary operating account for receiving US client ACH payments and Stripe payouts, with Wise used to move funds home to a Chilean account at a fair rate. This pairing is what makes the LLC genuinely useful day to day.
How this complements local rails matters. Domestically you already use the Chilean banking system, instant transfers between Chilean banks, and tools like Khipu for bank-to-bank payments or Global66 for cross-border movement. The LLC does not replace any of that. It sits in front of it. Dollars land in the US account from US clients, you keep a USD buffer there for US software and contractor costs, and you repatriate the rest to Chile on your schedule using Wise or Global66 when the peso rate is favorable. You stop bleeding margin on forced conversions every time a client pays, and you decide when to convert.
Relay is worth keeping in mind as a third option. It allows multiple sub-accounts under one login, which some Santiago founders use to separate operating cash, tax reserves, and a dollar savings buffer. Its non-resident onboarding is comparable to Mercury's and it can be a useful backup if a Mercury application stalls. Whichever provider you land, the goal is the same: a real US operating account in the LLC's name, fed by US clients and Stripe, with a clean, low-cost path back to your Chilean account. None of these are full Chilean banks and none replace your SII obligations; they are the US-side layer that makes getting paid in dollars frictionless.
Tax: US and your home country
The headline fact for Santiago founders is verified and favorable. The US-Chile income tax treaty entered into force on December 19, 2023, and its withholding provisions took effect for amounts paid or credited on or after February 1, 2024, per the U.S. Department of the Treasury and the IRS Chile tax treaty documents. Under the treaty, US withholding on dividends is capped at 15%, dropping to 5% for qualifying corporate shareholders, and royalties are limited to 2% for industrial, commercial, or scientific equipment and 10% for copyrights, patents, trademarks, and similar intangibles. Before this treaty, a Chilean recipient faced the default 30% US withholding on US-source FDAP income with no relief. To claim the reduced treaty rates, your LLC or you file Form W-8BEN-E (for the entity) or W-8BEN (for an individual) with the US payer.
For the typical Santiago services business, though, the treaty rates rarely come into play day to day. A single-member, foreign-owned Wyoming LLC is by default a disregarded entity. If your income is services performed by you outside the US for US clients, that income is generally foreign-source and not subject to US federal income tax at the LLC level. The treaty matters most when you have genuinely US-source passive income such as US dividends or royalties.
What every foreign-owned single-member LLC must do, regardless of whether it owes tax, is file. A foreign-owned disregarded LLC must file Form 5472 attached to a pro-forma Form 1120 each year, reporting reportable transactions between the LLC and its foreign owner. This is an information return, not a tax bill, but the IRS penalty for failing to file, filing late, or filing incomplete is $25,000 per the IRS Form 5472 instructions. Do not skip it. On the FinCEN side, there is good news: under the March 2025 interim final rule, US-formed entities, including foreign-owned US LLCs, are exempt from Beneficial Ownership Information reporting, per FinCEN. Your Wyoming LLC does not file a BOI report.
On the Chilean side, your worldwide income as a Chilean tax resident is still reportable to the Servicio de Impuestos Internos (SII). The LLC does not hide income from Chile, and how the LLC's profits are characterized for Chilean purposes depends on your situation. Confirm your specific treatment with a Chilean CPA familiar with foreign entities and the new treaty.
Popular use cases for Santiago founders
Santiago's startup scene, accelerated by Start-Up Chile and a deep pool of engineering and design talent, has produced a recognizable set of business types that pair well with a US LLC. The Wyoming LLC fits several patterns common in the city's economy:
- Software and SaaS studios building products for US and global users who need to bill in USD, run Stripe, and look like a US company to enterprise buyers.
- Development and design agencies serving US clients who prefer to contract with and pay a US vendor by ACH rather than wire pesos abroad.
- Independent developers and freelancers moving up-market from Upwork or Fiverr toward direct US clients and retainer relationships, where a US LLC raises perceived credibility and unlocks cleaner payment terms.
- Fintech and data founders who emerged from Chile's strong fintech scene and need a US entity to access US partners, APIs, and banking rails.
- E-commerce and digital product sellers using US payment processors and marketplaces that expect a US business and a US bank account.
- Consultants and B2B service providers invoicing US firms who want one US vendor record, one EIN, and predictable USD billing.
The common thread is a Santiago founder whose customers, platforms, or payment processors are US-based, and for whom a US entity removes friction that a Chilean personal account cannot. One LLC can carry several of these activities at once; you do not need a separate entity per product line, so a founder running both an agency and a small SaaS can invoice both through the same Wyoming LLC and EIN.
Step-by-step from Santiago
Santiago runs on Chile time, which is UTC-3 in summer and UTC-4 in winter, putting you only one to two hours ahead of US Eastern. That overlap is convenient: most US support hours fall within your working day, so banking follow-ups and verification calls do not require odd hours.
- Confirm your business basics. Decide your LLC name, your business activity description, and that you will be the single member. Have a clear one-line description of what you sell and who your US customers are, because banks will ask.
- Place the order ($397). This kicks off the Wyoming LLC formation. The Wyoming state fee is already included, so there is nothing extra to pay the Secretary of State.
- Formation files with Wyoming. The Articles of Organization are filed with the Wyoming Secretary of State, typically completing in about 24 hours. You receive your formation documents.
- EIN is obtained. Your EIN is requested from the IRS via Form SS-4. As a non-resident without an SSN, this is filed for you; the EIN confirmation is what banks and Stripe will require.
- Open your bank account. Apply to Mercury first (approval varies, not guaranteed) with your passport, Santiago address proof, EIN, and formation docs ready. Open Wise Business in parallel so you have a fallback and a cheap peso repatriation rail from day one.
- Connect Stripe and your payment stack. Register Stripe under the US LLC and EIN to accept US card payments and ACH. Wire your invoicing and SaaS billing to the US account.
- File W-8BEN-E where needed. If any US payer must withhold on US-source income, give them a W-8BEN-E to claim the Chile treaty rates instead of the default 30%.
- Calendar your compliance. Mark the annual Form 5472 plus pro-forma 1120 deadline and the Wyoming annual report. Set a reminder for the registered agent renewal so the LLC stays in good standing.
Because Santiago's time zone overlaps US business hours so well, most founders complete formation, banking, and Stripe within a week or two of starting.
Common mistakes
Skipping Form 5472. The single most expensive error. The information return is mandatory for foreign-owned single-member LLCs even with zero US tax due, and the penalty is $25,000. Treat it as non-negotiable and file every year.
Using a registered agent address for banking. Mercury and others rejected this in 2025. Use your real Santiago address as your principal business address on bank applications, and expect to prove it with a utility bill or statement.
Applying to a bank with a vague business description. "Consulting" with no detail and no revenue is what gets non-resident applications stuck or declined. Describe exactly what you sell and to whom before you apply.
Assuming the treaty erases all US tax automatically. The treaty reduces withholding on US-source dividends and royalties; it does not by itself make every payment tax-free, and you still must file W-8BEN-E to claim the rates. Most services income is foreign-source and outside US tax regardless, but do not conflate the two.
Ignoring the SII. A US LLC does not remove your Chilean reporting obligations on worldwide income. Engage a Chilean CPA who understands the new treaty so your Chile-side filings match your US structure.
Forgetting the annual report and agent renewal. Letting the ~$160/year lapse can put your LLC out of good standing, which jeopardizes your banking and your ability to contract. Calendar it.
