U.S. taxes for Americans in Chile: what to file, and how to catch up.
Santiago draws Americans working in mining, tech and education, and families with Chilean roots, and all of them still file a U.S. return every year. A U.S.-Chile tax treaty has applied since 2024, and Chilean tax usually covers the U.S. bill on wages. The details to get right are the AFP, voluntary pension savings and Chilean funds. Most people who fell behind can catch up under the Streamlined procedures, with no penalty if they qualify.
Sound familiar?
- You moved to Santiago for work and stayed.
- Part of your salary goes into an AFP every month.
- You save in APV for the Chilean tax break.
- Your Chilean bank asked about your U.S. citizenship.
How does the IRS treat the AFP and other Chilean accounts?
Every one of these goes on your FBAR. What differs is how the IRS taxes them.
| Account | U.S. treatment | |
|---|---|---|
| AFP pension payments | Under the new treaty, payments from the AFP system are taxable only in Chile, even for U.S. citizens. | Usually fine |
| AFP account while you work | How the U.S. treats the growth before you retire isn’t settled. The treaty covers the payments, not the years before. | Check first |
| APV (voluntary pension savings) | Tax-favored in Chile only. Growth may be taxable for the U.S., and some plans hold PFICs. | Check first |
| Chilean mutual funds | Usually PFICs (Form 8621), with complex reporting and tax rules. | Watch out |
| Bank accounts and depósitos a plazo | Interest is taxable for the U.S., and the accounts count toward your FBAR total. | Taxable |
| UF-indexed savings and mortgages | Inflation adjustments on UF savings can be taxable interest for the U.S., and paying off a peso or UF mortgage can create a currency gain. | Plan ahead |
Which Chilean investments are PFICs?
Chilean mutual funds (fondos mutuos) and investment funds, and the funds inside many APV plans. For U.S. tax they’re passive foreign investment companies, or PFICs, with their own reporting and harsh default tax rules.
- Each fund needs its own Form 8621 in most years, and gains can be taxed at the top U.S. rate plus an interest charge, unless an election was made in time.
- The AFP’s own funds, the A to E funds, are a separate question that depends on how the AFP account is treated, which isn’t settled.
- Not PFICs: shares of individual companies on the Santiago exchange, Chilean government bonds, and bank deposits.
What does the U.S.–Chile tax treaty actually say?
The treaty was signed in 2010 and finally took effect in 2024. For Americans living in Chile, these parts matter most:
- The saving clause. The U.S. can tax its citizens as if the treaty didn’t exist, except for the provisions the treaty lists.
- AFP pensions. Payments from Chile’s pension system are taxable only in Chile, even for U.S. citizens.
- U.S. Social Security. The U.S. taxes it as usual, and Chile can’t.
- Relief from double tax. The U.S. gives a credit for Chilean income tax on the same income, as it did before the treaty.
Social security contributions are covered by a separate U.S.–Chile agreement, which generally means you pay into one system, not both. Read the U.S.–Chile tax treaty on IRS.gov.
When are Chilean and U.S. taxes due?
Both tax years run January to December, so each Chilean year lines up with one U.S. return.
| Chile | United States | |
|---|---|---|
| Tax year | January to December | January to December |
| Annual return | The Operación Renta in April, by April 30, often pre-filled by the SII | April 15, moved to June 15 automatically when you live abroad, or October 15 with an extension |
| Paying the tax | Withheld from your salary, with any balance due with the return | April 15, even if you file later |
| Foreign accounts | Foreign income goes on the Chilean return | The FBAR, due October 15, filed online |
Foreign tax credit or exclusion: which wins in Chile?
It depends on your salary. Chilean rates climb to 40%:
- Higher earners usually do best with the foreign tax credit, which covers the U.S. tax on the salary.
- At moderate salaries, Chilean tax can be less than the U.S. tax, so the foreign earned income exclusion, up to $130,000 for 2025, may do more.
- Families with children often keep the credit, because it allows the refundable part of the U.S. child tax credit, up to $1,700 per child for 2025.
We run your returns both ways before choosing. How we compare the exclusion and the credit.
A worked example: an engineer in Santiago
Diego was born in Houston to Chilean parents and moved to Santiago for a mining company in 2016. He pays into an AFP, saves in an APV invested in a mutual fund, and holds another Chilean fund at his bank. He has never filed a U.S. return.
| Item | How it’s handled |
|---|---|
| Salary | We compare the exclusion and the credit; either way his U.S. tax on it is usually little or nothing. |
| AFP | On the FBAR. Its payments will be taxable only in Chile; how its growth is treated before then is unsettled, so we explain the options. |
| APV and bank fund | PFICs: a Form 8621 for each, in each year filed. |
| Years before 2024 | Filed without the treaty, with Chilean tax still credited. |
| Catching up | Three years of returns and six FBARs under the Streamlined procedures, with no penalty if he qualifies. |
Catching up from Chile
Most Americans in Chile who fell behind without meaning to can catch up under the Streamlined Foreign Offshore Procedures: three years of returns, six years of FBARs and, if you qualify, no penalties. If only FBARs are missing, or you’ve moved back to the U.S., another route may fit better. See every IRS catch-up option for expats, compared.
Common questions
Do I pay U.S. Social Security tax in Chile?
Generally not if you pay into the Chilean system. The U.S.-Chile totalization agreement prevents paying into both systems for the same work in most cases.
Will the U.S. tax my U.S. Social Security in Chile?
The U.S. taxes it as usual. Under the treaty, Chile can’t.
Did the new treaty change my past years?
No. It applies from 2024, so catch-up years before that are handled without it. Chilean tax still counts toward your U.S. foreign tax credit for those years.
Is my AFP taxed by the U.S.?
The payments, once you retire, are taxable only in Chile under the treaty. Before then, how the U.S. treats the account’s growth isn’t settled, and we explain the options before you file.
Is my APV tax-deferred for the U.S.?
Not necessarily. It’s tax-favored in Chile only, so growth may be taxable for the U.S., and funds inside are often PFICs.
How do you handle pesos and UF amounts?
We convert using the correct IRS exchange rates for each year and account, and treat UF inflation adjustments the way the U.S. rules require. It’s routine for us.
