US-Nicaragua tax obligations

If you’re a Nicaraguan citizen living in the US or US citizen with assets in Nicaragua, you have cross-border tax obligations with two systems: US IRS and Nicaragua tax authority. This guide covers main points.

Official IRS tax treaty status — verified data

Official source: IRS — US Income Tax Treaties A-Z

Verified on: 2026-05-25

❌ Nicaragua does NOT have a tax treaty with the US (verified against IRS on 2026-05-25).

NOT on IRS treaty list

Latin American countries with US tax treaty

Only 3 Latin American countries have a tax treaty with the US (IRS data 2026):

  • Chile (signed 2010; entered into force December 19, 2023 — US Treasury; effective for withholding at source from February 1, 2024)
  • Mexico (signed 1992, amended 2002)
  • Venezuela (signed 1999)

Without treaty: what happens

If Nicaragua has NO tax treaty:

  • Nicaragua income is subject to US tax if you’re a US tax resident
  • NO reduced withholding rates on dividends/interest
  • Can claim Foreign Tax Credit (Form 1116) to avoid double taxation

Your Nicaragua tax ID

In Nicaragua, the tax ID is called Nicaragua RUC. If you worked or had income in Nicaragua, you should have one.

Your US tax ID

  • If you have SSN: use it
  • If you don’t have SSN: you need ITIN from IRS — see ITIN complete guide
  • ITIN allows fulfilling US tax obligations without work authorization

⚠️ NO US-Nicaragua tax treaty

The US and Nicaragua do NOT have a bilateral tax treaty. This means:

  • 30% withholding on most US passive income paid to Nicaraguan non-residents (dividends, royalties, rents, and interest — though interest on US bank deposits is generally exempt)
  • NO automatic treaty reduction
  • Possible double taxation: paying Nicaraguan tax authority on US-source income + IRS on same income
  • US Tax Credit (Form 1116) available for credits for taxes paid to Nicaragua (mitigates but doesn’t eliminate)

FBAR (FinCEN 114) — accounts in Nicaragua

If you’re a “US Person” (US citizen, permanent resident, or tax resident via Substantial Presence) and have bank accounts in Nicaragua whose combined balances exceeded $10,000 USD at any point in the year, you MUST file FBAR (FinCEN Form 114) annually.

  • Deadline: April 15 (automatic extension to October 15)
  • Cost: FREE (electronic via bsaefiling.fincen.gov)
  • Penalties: $10,000-$100,000+ for non-filing

See: FBAR complete guide

FATCA (Form 8938) — assets in Nicaragua

If your Nicaragua financial assets (bank accounts, stocks, funds) exceed FATCA thresholds, you must file Form 8938 with your federal IRS return.

Thresholds (US Persons living in the US) — each has TWO prongs, and hitting either one triggers the form (IRS, Summary of FATCA reporting for U.S. taxpayers):

  • Single / married filing separately: more than $50,000 on the last day of the tax year, OR more than $75,000 at any time during the year
  • Married filing jointly: more than $100,000 on the last day of the tax year, OR more than $150,000 at any time during the year
  • If you live abroad, the thresholds are much higher: $200,000 / $300,000 single, $400,000 / $600,000 married filing jointly

The any-time-during-the-year prong is the one people miss: a balance that peaked at $80,000 in July and sat at $40,000 on December 31 still requires Form 8938.

US + Nicaragua dual nationality

Since January 16, 2026, Article 25 of Nicaragua’s Constitution, as reformed by Law No. 1268 (La Gaceta No. 09, January 16, 2026), reads: «La nacionalidad nicaragüense se perderá al momento de adquirir otra nacionalidad» (Nicaraguan nationality shall be lost upon acquiring another nationality). The previous text said nationality was not lost by acquiring another. The official texts do not say how the rule is applied in practice, or how it applies to people who acquired another nationality before 2026 or hold one from birth. Full text and open questions: Nicaragua dual nationality: what Law 1268 says.

Dual nationality tax implications:

  • You still owe US tax on worldwide income (the US taxes its citizens on worldwide income)
  • You may also owe tax in Nicaragua on income generated in Nicaragua
  • The US foreign tax credit (Form 1116) can reduce double taxation on income that Nicaragua also taxes

Currency and conversion

Nicaragua: NIO (Córdoba). When reporting Nicaraguan income to the IRS, convert it to US dollars, generally at the exchange rate prevailing when you receive, pay or accrue the item; the IRS has no official exchange rate and generally accepts any posted exchange rate used consistently.

If you have a business (Self-Employment / Independent Contractor)

If you live in US with ITIN and have freelance/business income:

  • Schedule C (business profit/loss)
  • Schedule SE (Self-Employment Tax 15.3%)
  • 1099-NEC from your US clients
  • FEIE does NOT apply (you’re IN the US, not abroad)
