Peru has no US tax treaty and no totalization agreement — and taxes anyone domiciled there on worldwide income.
There is no US–Peru income tax treaty and no totalization agreement. Peru taxes on domicile: a foreign national who is in the country for more than 183 days in a 12-month period is domiciled there and taxed on worldwide income, while someone who is not is taxed only on Peruvian-source income. The consequence for the US return is a Peruvian tax that is creditable but has no treaty to resolve disagreements, with self-employment tax running at 15.3%.

What that means on your return
The 183-day test is counted over any 12-month period, not the calendar year, and short absences do not interrupt it. Status is fixed at the start of the fiscal year, so a change takes effect from 1 January of the following year. A first partial year can sit on the non-domiciled side even after the 183rd day.
The two sides are taxed very differently. A domiciled individual is taxed on worldwide income on a five-bracket scale from 8% to 30%, counted in tax units (the 2026 unit is 5,500 soles), with the first seven units exempt. A non-domiciled employee pays a flat 30% on gross Peruvian-source income, with no deductions and no credits.
Peruvian income tax is creditable on Form 1116 under the ordinary statutory rules. What a treaty would add is missing: a residency tie-breaker, a pension article and a way to resolve a disagreement between the two systems.
Tax paid on income you exclude under the foreign earned income exclusion cannot also be credited, so the choice between exclusion and credit is made on the numbers and can change from year to year as Peruvian tax changes.
Peru taxes income from leases and gains on shares at an effective 5% for domiciled individuals. The US taxes the same income at its own rates and limits the credit to the US tax on that income, so a low Peruvian rate leaves US tax to pay.

Questions I get about Peru
Is there a US–Peru tax treaty?
No. The IRS list of treaties in force does not include Peru, and there is no totalization agreement either, so US self-employment tax applies at 15.3%.
Can I still credit Peruvian tax without a treaty?
Yes. The foreign tax credit comes from the Internal Revenue Code, so Peruvian income tax actually paid is creditable on Form 1116. What you lose is the treaty machinery.
When do I become domiciled in Peru for tax?
When you have been in Peru for more than 183 calendar days within a 12-month period. The status is set at the start of the fiscal year, so a change takes effect from 1 January of the next year.
What does Peru tax if I am not domiciled?
Only Peruvian-source income. An employee pays a flat 30% on gross Peruvian-source income, with no deductions or credits, which is why the date domicile starts is worth getting right.
When is my return due?
15 June, under the automatic extension for filers living abroad. Form 4868 moves it to 15 October, and I file the extension free.
Do I have to file an FBAR for my Peruvian bank account?
If your foreign accounts together passed $10,000 at any point in the year, yes. You can file it free through FinCEN's own system. The non-willful penalty for not filing is $16,536.
I have not filed for several years. What now?
The Streamlined Foreign Offshore Procedures: three returns, six FBARs and Form 14653 certifying non-willfulness. Penalties are waived. Note that the IRS terminated the separate Delinquent FBAR Submission Procedures around 1 July 2026.
Filing from Peru this year?
Fifteen minutes with the Enrolled Agent who will prepare and sign it. Complete return, $599.
An IRS Enrolled Agent working only on US tax for Americans living abroad. I prepare and sign every return myself — 14 years in practice, 11 of them as an Enrolled Agent.
