Expat Tax Residency in Chile

Foreign nationals who move to Chile encounter a tax system that is generous in its opening years but transitions to full worldwide-income taxation once a multi-year exemption window expires. Understanding when residency begins, how the exemption works, and what brackets apply after it closes is essential groundwork before a cross-border move.

When does Chile tax residency begin?

Chile's Servicio de Impuestos Internos (SII) applies two overlapping concepts: residence and domicile. Under the 2020 regulatory update confirmed by the International Tax Review [ITR-2020], residency attaches when an individual spends 183 days within any 12-month period on Chilean soil -- consecutive or not. The earlier statutory language referencing six months in one calendar year or across two consecutive years still appears in the Income Tax Law as an alternative trigger (PwC Worldwide Tax Summaries [PWC-CHL]), but the 183-day rolling test is the operative SII standard post-2020. Domicile is established the moment an individual arrives with clear intent to remain permanently or for a substantial period; where domicile precedes the 183-day count, normal resident taxation applies from the date of entry.

What is the 3-year foreign-income exemption?

Article 3 of Chile's Income Tax Law grants a transitional benefit to new foreign residents: during the first three years of residence or domicile in Chile, the individual is taxed only on Chilean-source income. Foreign-source income -- wages from a foreign employer, dividends from overseas holdings, rental income from property abroad -- falls outside Chilean taxable income entirely during this window (SII, The Chilean Income Tax System [SII-ENG]; PwC [PWC-CHL]). After three years the resident may apply to the SII for a further three-year extension; if granted, the exemption stretches to a maximum of six years in total. Once the window closes, Chile taxes the resident on worldwide income at the full progressive rates. The extension is not automatic -- the SII evaluates the application -- so residents who wish to preserve the exemption should file before the initial three years expire.

How does the Global Complementary Tax work?

Residents who have exited the exemption window -- or who earn Chilean-source income at any point -- face the Impuesto Global Complementario (Global Complementary Tax). This is an annual progressive tax assessed on total annual income, distinct from the monthly Second-Category Tax withheld on employment wages throughout the year. The brackets below use annual thresholds derived from the Unidad Tributaria Mensual (UTM) index. The UTM is adjusted monthly by the SII; the figures below correspond to a UTM of CLP 70,588 as of May 2026 (Country Tax Calc, Chile Tax Calculator 2026 [CTC-2026]).

The SII's Circular No. 09 of January 2025 set the inflation-adjusted brackets for tax year 2025 using a Unidad Tributaria Anual (UTA) value of CLP 807,528 as of December 2024 (Orbitax, Chilean Tax Authority Issues Circular on Inflation Adjustments [ORBITAX-2025]). Thresholds shift each year as the UTM moves; always confirm the current UTM at sii.cl before computing liability.

Non-residents who earn Chilean-source income face a flat Additional Withholding Tax -- generally 35 percent on most income types, or 15 percent on payments for technical, engineering, and professional services rendered from abroad (PwC [PWC-CHL]). The flat rate applies without the progressive bracket structure until the individual crosses into residency.

How do foreigners register with the SII?

All foreign individuals who generate or may generate taxable income in Chile must obtain a Rol Unico Tributario (RUT), the national taxpayer identification number administered by the SII. The RUT doubles as the civil Rol Unico Nacional (RUN) for immigration and identification purposes. Registration is completed online through the SII portal using an identity document -- the foreigner's identity card issued in Chile, or a valid passport if the card has not yet been issued (SII, Inscripcion al RUT para Extranjeros [SII-RUT]). A residence visa that permits income-generating activity is required for individuals who also intend to begin commercial activities. The SII's January 2025 Circular N 26 and Resolution N 42 of April 3, 2025 updated certain procedures for foreign contributors. The annual income tax return is filed on Form 22, due April 30 of the year following the tax year. For the Chile country overview see the country page, which covers corporate tax, VAT at 19 percent, and the overall business environment.

The diagram above illustrates the three phases of Chilean taxation for new foreign residents: Chilean-source only through year three, the same treatment through year six if the SII grants an extension, and full worldwide-income exposure thereafter. For a detailed look at capital gains, dividends, and corporate structures, see the Chile country overview.

The rules above describe the general legal framework published by the SII and cross-referenced against PwC Worldwide Tax Summaries. Individual circumstances -- domicile timing, source-of-income classification, applicable double-tax conventions -- can alter outcomes significantly. A qualified tax professional with Chilean and cross-border experience is the appropriate contact for situation-specific guidance.
