Quick Reference table
| Field | Value | |---|---| | Country | Republic of Costa Rica | | Currency | CRC (colón, ₡) | | Headline levers | **Territorial system** (only CR-source income taxed); Régimen Simplificado for small business; exempt minimum | | ISR (self-employed/individual) | Progressive; **exempt up to ~₡10,104,000/yr** (~USD 19,800) | | Dividends / passive income | 15% | | Anti-avoidance | Régimen Simplificado eligibility; substance |
Territorial taxation scope
Only Costa-Rica-source income is subject to ISR; genuinely foreign-source income is generally not taxed. Important for residents with international income — but the source rules are fact-specific and increasingly scrutinised (passive-income / shell rules).
RTS feature table
| Feature | Detail | |---|---| | Who | Small taxpayers meeting the limits | | Limits (2026) | Annual purchases up to ~₡85,969,200; **max 5 employees**; single establishment; fixed assets ≤ 350 base salaries | | VAT | RTS taxpayers **do not charge VAT** on sales | | ISR | Computed by applying a "rent factor" to the quarterly purchase base (form D-105-2) |
Exempt minimum usage
Self-employed/individual ISR is progressive with an exempt minimum (~₡10.1m) — ensure it's used.
Dividends / passive income rate
15%
Source rules red line
Foreign-source exemption only applies to genuinely foreign income — don't relabel Costa-Rican-source income.
RTS eligibility red line
RTS eligibility (purchases, employees, single establishment, asset cap) — confirm before electing.

Costa Rica is TERRITORIAL — only Costa-Rica-source income is taxed. Genuinely foreign-source income is outside scope. Plus a Régimen de Tributación Simplificada for qualifying small businesses and a sizeable exempt minimum.
AUDIT FLASH POINT — confirm the income is genuinely foreign-source; "Costa Rican economic structure" can drag income into scope.
