US tax for Americans in Ecuador
Ecuador has no US income tax treaty and no totalization agreement. It taxes residents on worldwide income once they are present for more than 183 days, but a temporary tax residency regime in place since January 2024 can limit new arrivals to Ecuadorian-source income for five years, on conditions. It also uses the US dollar, so there is no exchange rate to apply on the return.
Counting the 183 days
Ecuadorian tax residence follows presence: more than 183 days in Ecuador, including occasional absences, within one fiscal year or within a 12-month period that straddles two fiscal years. Other conditions can also apply, because the rules look at economic and personal ties as well as the count.
A five-year regime for new arrivals
Since January 2024, people with no previous Ecuadorian tax residence who meet further conditions can use a temporary tax residency regime. For up to five years they are taxed on Ecuadorian-source income only. While it applies, income from outside Ecuador faces no Ecuadorian tax, so there is nothing to credit and the exclusion does the work.
The conditions are what decide it, and they should be confirmed against your own facts before you rely on the regime. After the five years, residents are taxed on worldwide income.
Worldwide income, with a credit
Outside that regime, residents are taxed on income generated abroad on a progressive scale reaching 37%, with a credit for tax paid there up to the Ecuadorian tax attributable to that income. Ecuadorian income tax actually paid is creditable on Form 1116.
A dollar economy
Ecuador uses the US dollar, so income and tax are already in dollars. The return needs no exchange-rate translation, which removes one common source of disagreement between the two sets of figures. It does not change what you owe or what you file.
No treaty, no tie-breaker
With no treaty there is no tie-breaker if both countries claim you as a resident, and no pension article. With no totalization agreement, self-employment tax runs at 15.3%, and Ecuadorian social security (IESS) contributions are not income tax and are not creditable.
A worked example, tax year 2025
A single American consulting from Quito, $$110,000 of net self-employment earnings, with the 330-day test met. The US figures are computed.

| US income tax after the exclusion | $0 |
| Self-employment tax, no totalization agreement | $15,543 |
| Treaty relief available | None — there is no treaty |
| Exchange-rate translation needed | None — Ecuador uses the US dollar |

Questions Americans in Ecuador ask
Is there a US–Ecuador tax treaty?
No. The IRS list of treaties in force does not include Ecuador, and there is no totalization agreement either, so US self-employment tax applies at 15.3%.
Does Ecuador tax my income from outside Ecuador?
Once you are a tax resident, yes: resident individuals are taxed on income generated abroad, with a credit for tax paid there. Under the temporary tax residency regime available since January 2024, eligible people are taxed on Ecuadorian-source income only for five years.
Do I credit Ecuadorian tax on my US return?
Yes. Ecuadorian income tax actually paid is creditable on Form 1116 under the statutory rules. Tax on income you exclude under the foreign earned income exclusion cannot also be credited.
Does Ecuador's use of the dollar change my US filing?
It removes the exchange-rate translation, nothing more. A US citizen files a US return wherever they live, and the FBAR applies once foreign accounts together exceed $10,000.
I have not filed for several years while in Ecuador. What now?
If the failure was non-willful — which describes most people in this position — the Streamlined Foreign Offshore Procedures waive the failure-to-file, failure-to-pay and FBAR penalties: three years of returns, six years of FBARs, and Form 14653.
Filing from Ecuador?
Fifteen minutes settles whether the temporary regime applies to you and what the exclusion leaves.
