In short
- You become tax resident in Chile after more than 183 days within any 12-month period, or sooner if you move here with the intention to stay.
- For the first three years of residence, foreigners are taxed in Chile only on Chilean-source income. U.S. citizens keep filing with the IRS every year regardless.
- The U.S.–Chile income tax treaty has been in force since December 2023, and a social security agreement since 2001 prevents paying into both systems on the same work.
- Get your RUT early. It is your tax number in Chile and you need it for a bank account, a lease, a phone plan and healthcare.

Everyday life
Chile runs on a long, narrow map. Most people live in the central valley around Santiago, but the country stretches 4,300 kilometers from the Atacama Desert to Patagonia, and the change of scene is part of the appeal. Life is orderly by regional standards: public services work online, contracts are formal, and banks and utilities are reliable.
Spanish matters. Chilean Spanish is fast and full of local words (al tiro, cachai, pololo), and even fluent speakers take a few months to tune in. People are reserved at first and warm once they know you, and family runs through social life: the Sunday almuerzo, the September Fiestas Patrias, long summer holidays in January and February.
Visas and residence
Visitors from the U.S. can enter as tourists without a visa in advance. To live in Chile you apply for temporary residence under the 2021 migration law, through the Servicio Nacional de Migraciones online platform. There are several subcategories, including work with a Chilean employer, family ties to a Chilean or a resident, retirees and people with their own income, investors, and students. Most first applications must be filed from abroad.
Temporary residence can be renewed and, after the required time, leads to definitive (permanent) residence. Start collecting apostilled documents (birth and marriage certificates, police records) before you move; they are the usual cause of delays.
Where people settle
- Santiago: jobs, schools, the international airport and most services. Providencia, Ñuñoa, Las Condes and Vitacura are the usual starting points, with the Andes on the skyline and ski areas an hour away.
- Valparaíso and Viña del Mar: the coast 90 minutes from Santiago. Valparaíso is bohemian and hilly; Viña is calmer, with beaches and apartments by the sea.
- La Serena and the north: sun most of the year, a slower pace, and the Elqui Valley's clear night skies.
- The Lakes District (Los Lagos and La Araucanía): Puerto Varas, Frutillar, Osorno and Pucón, with volcanoes, lakes and German-Chilean heritage. Popular with families and retirees who want space and nature, and a gateway to Chiloé and Patagonia.
Healthcare
Chile has a public and a private system, and residents choose. Employees pay 7% of taxable salary for health, which goes either to Fonasa, the public insurer, or to an Isapre, a private plan that may cost more on top. Fonasa gives access to public hospitals and, at higher tiers, to private clinics at set prices. Isapres offer wider private networks. Santiago and the large southern cities have well-equipped private clinics; rural areas rely more on regional hospitals.
Medicare does not cover care in Chile, so people retiring here usually combine Fonasa or an Isapre with international insurance.
Money, the RUT and banking
- RUT: your Chilean tax ID. Residents get it with their identity card (cédula de identidad); others can request one from the SII. Almost every contract asks for it.
- Bank accounts: BancoEstado's CuentaRUT is the simplest first account. Full current accounts at private banks usually require residence and income history.
- UF: the Unidad de Fomento rises daily with inflation. Rent quoted in UF keeps its real value, so budgets in pesos drift upward over a lease.
- U.S. accounts: most people keep them. Some U.S. brokers restrict accounts for clients living abroad, so check before you move.
Every Chilean account counts toward the FBAR. See AFP, APV and the FBAR.
Housing
Rentals are listed on Portal Inmobiliario and similar sites, often in UF. Expect a month's deposit, a guarantor (aval) or proof of income, and a notarized lease. Foreigners can buy property in Chile with a RUT, without residence. Buying is handled through a notary and registered at the Conservador de Bienes Raíces; owners pay contribuciones, the property tax, in four installments a year. Chile's 2026 reform exempts the first sale of qualifying new homes from VAT until November 2027.
How your taxes work in both countries
In Chile
You become tax resident after more than 183 days in any 12-month period, or earlier if you move with your family, set up home and arrive with an employment contract. Residents are taxed on worldwide income, but foreigners are taxed only on Chilean-source income for their first three years, and the period can be extended. Salaries are taxed monthly through withholding at progressive rates up to 40%; other income is declared once a year on Formulario 22 in April.
In the U.S.
U.S. citizens and green card holders file every year wherever they live. Most people in Chile end up owing little or no U.S. tax by using the foreign tax credit or the exclusion, but the filings still matter: Form 1040, the FBAR for Chilean accounts, and depending on your situation Form 8938, Form 8621 for Chilean funds and Form 5471 for a Chilean company.
Where they meet
- The income tax treaty (in force since December 2023) decides which country taxes pensions, dividends and other items first and lowers withholding.
- The social security agreement generally means you contribute to only one system for the same work, and lets periods in both countries count toward benefits.
- April is the crunch month: Chile's Operación Renta and the nominal U.S. due date land together. Your Chilean figures feed the U.S. foreign tax credit, so the two returns should be prepared from the same numbers.
Frequently asked questions
Do I still file U.S. taxes if I live in Chile?
Yes, if you are a U.S. citizen or green card holder above the filing thresholds. Living abroad gives you until June 15 automatically, and most people owe little or nothing after credits.
Will Chile tax my U.S. income?
Not during your first three years of Chilean residence, unless it is Chilean-source. After that, Chile taxes worldwide income and credits foreign tax under the treaty.
Can I keep contributing to U.S. Social Security?
If you work for a U.S. employer temporarily sent to Chile, the agreement can keep you in the U.S. system. If you work for a Chilean employer, you usually contribute in Chile, to an AFP and health.
Is my AFP reportable to the IRS?
Most preparers report it on the FBAR, and it counts for Form 8938 above the thresholds. See our AFP guide.
