LLC vs C-Corp for Costa Rican Founders: The Honest Breakdown
Costa Rica has one of the most stable business environments in Central America, a growing tech sector, and a significant number of founders building U.S. companies from San José. The entity choice — LLC or C-Corp — carries specific implications given Costa Rica's tax treaty status with the United States.
The U.S.–Costa Rica Tax Treaty: Does One Exist?
No. The United States and Costa Rica do not have a bilateral income tax treaty. The U.S. Senate has not ratified a treaty with Costa Rica, which means the default U.S. withholding tax rate applies.
| WHT category | Rate (no treaty) |
|---|---|
| Dividends from C-Corp | 30% |
| Interest | 30% |
| Royalties | 30% |
| LLC distributions (pass-through) | 0% (no entity-level WHT) |
The 30% withholding tax on C-Corp dividends is the most important number for Costa Rican founders to understand.
The Double-Taxation Math
If you form a Delaware C-Corp and eventually pay yourself dividends as a Costa Rican resident:
- The C-Corp pays U.S. corporate income tax (21%) on its profits
- The dividend is then subject to 30% U.S. WHT (no treaty reduction)
- Costa Rica's Dirección General de Tributación (DGT) may also tax the dividend as foreign income
The combined tax burden on a $100 profit can exceed 50% before you see the money.
The LLC Advantage for Costa Rican Founders
A U.S. LLC owned by a non-U.S. person (a Costa Rican resident with no U.S. ties) is a pass-through entity. The LLC itself pays no U.S. tax. Distributions to a foreign owner are not subject to the 30% WHT that applies to C-Corp dividends.
Costa Rica taxes residents on worldwide income. LLC income attributed to a Costa Rican resident is potentially taxable in Costa Rica — but at Costa Rican rates (typically 15–25% for business income), not the punishing 30% U.S. WHT layer.
C-Corp vs LLC: The Decision Table
| Factor | C-Corp | LLC |
|---|---|---|
| U.S. WHT on distributions | 30% (no treaty) | 0% (pass-through) |
| Costa Rica income tax | Potentially on net | On attributed income |
| VC/institutional fundraising | Required | Incompatible |
| Delaware Franchise Tax | Yes (~$400–$1,600/yr) | Yes (~$300/yr) |
| Complexity | Higher | Lower |
| Best for | VC-track only | Bootstrapped, consulting, SaaS |
Practical Recommendation
Bootstrapped or consulting founders: The LLC is the clear choice for Costa Rican founders. The absence of a U.S.–Costa Rica tax treaty makes the C-Corp dividend tax extremely punishing. An LLC avoids the 30% WHT entirely.
VC-track founders: You will need a Delaware C-Corp to raise institutional capital. Accept the 30% WHT as a cost of the VC path, and structure your compensation as salary (which has different withholding rules) rather than dividends where possible.
Important: Costa Rica's DGT has been expanding its international tax enforcement. Ensure your LLC is properly reported on your Costa Rican tax return as foreign-source income.
