Chile, Uruguay or Paraguay: Where to Open a Company
We compare taxes, timelines, and treaty networks in Chile, Uruguay, and Paraguay for anyone weighing where to open a company in South America in 2026.
The most common comparison a foreign entrepreneur finds when searching “where to open a company in South America” is a table of rates: Paraguay at 10% corporate income tax, Uruguay at 25%, Chile at up to 27%. But deciding based on that single line is like choosing a bank by a credit line’s interest rate without looking at the rest of the contract — the nominal rate is real, but it’s far from the variable that weighs most in the final tally.
This guide compares Chile, Uruguay, and Paraguay on the four factors that actually determine whether a company opened abroad works in practice: effective tax burden, time and cost of formation, treaty network for avoiding double taxation, and what tends to be the real bottleneck — access to a bank account.
Tax landscape compared
| Criterion | Chile | Uruguay | Paraguay |
|---|---|---|---|
| Corporate tax (general regime) | 27% (semi-integrated regime, Art. 14 A) | 25% (IRAE) | 10% (IRE) |
| Reduced regime for small businesses | 12.5% under the Pro Pyme regime, temporary reduction in force through 2027 | No equivalent general regime; depends on the corporate structure | Already 10% for practically all sizes |
| VAT / consumption tax | 19% | 22% | 10% |
| Fully digital formation | Yes — “Company in a Day” (Law 20,659) | Yes — SAS (Law 19,820) | Partial, with in-person steps before a notary and the SET (tax authority) |
| Legal formation timeline | Up to 2 business days through the online portal, once documentation is ready | 24 to 72 hours to register the SAS | Generally weeks, between notary and Tax Administration Office |
| Double taxation treaty network | More than 33 countries, including Brazil | A broad network, also including a treaty in force with Chile and Brazil | A considerably more limited network |
What the table doesn’t show: real time until you can invoice
A recurring mistake is confusing “forming the company” with “being operational.” In Chile and Uruguay, the company’s legal registration can come through in under three days — but that doesn’t include opening the corporate bank account, which tends to be the slowest step in any of the three countries when the shareholder is a foreign national without local residency. Market reports put bank account opening at 1 to 3 weeks in Uruguay alone, with a similar or longer timeline in Chile when the account holder doesn’t have a RUT linked to residency.
In other words: the “one day” timeline advertised on formation portals is real for legal registration, but rarely reflects the total time until the company can actually issue its first invoice.
What the tax figures don’t capture: legal certainty and international network
A 10% rate in Paraguay looks unbeatable in isolation, but three factors deserve consideration before deciding:
- Tax treaty network. Chile maintains double taxation treaties with more than 33 countries, including Brazil — which reduces withholding at source on dividends, interest, and royalties remitted between the two countries. Paraguay’s network is considerably more limited, which can raise the effective tax burden on international remittances, even with the lower nominal rate.
- Institutional stability and international banking access. International correspondent banks and institutional investors tend to require more documentation and due diligence for structures in jurisdictions with a less established tax track record — which can translate into more banking bureaucracy, not less.
- Recent regime changes. Uruguay approved, in its 2025-2029 Budget Law, changes that begin treating certain passive foreign-source income as Uruguayan-source starting January 1, 2026 — a reminder that “territorial regime” isn’t synonymous with “unchanging rule” in any of the three countries.
Disclaimer: the rates and timelines cited reflect the regulations in force as of publication. Tax systems in the region have been undergoing frequent changes — Uruguay itself amended its rules on taxing passive foreign-source income for 2026. Before structuring an operation, confirm the current regulations directly with the tax authority of the chosen country.
When Paraguay or Uruguay make more sense than Chile
Being honest about this is part of what separates serious analysis from a sales pitch:
- Paraguay tends to make sense for low-volume operations with little need for international financing access or double taxation treaties — for example, simple regional trade or straightforward wealth-holding structures, where the low nominal tax burden outweighs the treaty network.
- Uruguay competes directly with Chile on agility and reputation, and can be preferable for those who already have operations or clients in the Río de la Plata region (Argentina, southern Brazil), given the logistical and cultural proximity, in addition to maintaining a double taxation treaty with Brazil.
When Chile makes more sense
- Operations that depend on a broad double taxation treaty network — not just with Brazil, but with third countries (Europe, Asia, North America), where Chile’s network of more than 33 treaties offers more predictability.
- Businesses looking to combine forming the company with a migration project — anyone already considering relocating to Chile as a rentier, investor, or for work has, within the same jurisdiction, an integrated corporate and immigration path.
- Sectors that depend on access to capital markets, international bank financing, or institutional partners, who tend to value Chile’s track record of regulatory stability and its OECD membership.
Step-by-step summary: opening a company in Chile with Company in a Day
- Choose the corporate type. The SpA (Sociedad por Acciones) is the most commonly used option because it allows a single shareholder and a flexible structure.
- Access the registrodeempresasysociedades.cl portal, run by the Ministry of Economy, using a digital ID or an authorized representative.
- Complete the standard bylaws offered by the system itself — automatic drafting is what makes this process free.
- Obtain the company’s RUT automatically, generated in the same filing.
- File the commencement of activities with the SII, defining the tax regime (Pro Pyme or general regime, depending on size and projected income type).
- Publish the extract in the Official Gazette, free for companies with capital under UF 5,000.
- Obtain the municipal business license before beginning formal operations.
- Open the corporate bank account — the step that, in practice, tends to determine the real timeline until the company can start invoicing.
Most common mistakes in this decision
- Comparing only the nominal rate, ignoring the treaty network and the effective tax burden on international remittances.
- Assuming “formation in a day” means “operational in a day” — opening a bank account tends to be the real bottleneck in any of the three countries.
- Choosing a jurisdiction without considering future migration plans, missing the chance to integrate the corporate strategy with an eventual change of residency.
- Ignoring recent tax regime changes, like Uruguay’s new rule on passive foreign-source income starting in 2026.
Frequently asked questions
Which country has the lowest corporate tax among the three?
Paraguay, with a 10% Business Income Tax (IRE), the lowest nominal rate of the three. But the nominal rate doesn’t equal the effective tax burden of an operation with frequent international remittances.
Does Chile have a double taxation treaty with Brazil?
Yes. Chile and Brazil maintain a double taxation treaty in force, part of a Chilean network of more than 33 such agreements.
Is forming a company in Chile really free?
Registration through the Company in a Day platform doesn’t charge for the formation itself when using the standard bylaws. However, there are associated costs — digital certificate, accounting, an eventual municipal license — that should factor into the real first-month budget.
Does opening a company in another country automatically give me the right to live there?
No. Forming a company and obtaining immigration residency are separate, though related, processes. In Chile, for example, being a company shareholder doesn’t replace the need to assess the appropriate residency subcategory (investor, work, among others).
Conclusion
There’s no universal answer to “where to open a company in South America” — there’s the right answer for each operation’s profile, its volume of international remittances, and each family’s or entrepreneur’s migration plans. Paraguay wins on nominal rate; Uruguay competes closely with Chile on agility and cultural proximity; Chile stands out when the operation depends on a broad treaty network, institutional stability, or an immigration strategy integrated with the corporate one.
