US-Dominican Republic tax obligations

If you’re a Dominican citizen living in the US or US citizen with assets in Dominican Republic, you have cross-border tax obligations with two systems: US IRS and Dominican Republic 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

❌ Dominican Republic 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 Dominican Republic has NO tax treaty:

  • Dominican Republic 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 Dominican Republic tax ID

In Dominican Republic, the tax ID is called RNC (National Taxpayer Registry). If you worked or had income in Dominican Republic, 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-Dominican Republic tax treaty

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

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

FBAR (FinCEN 114) — accounts in Dominican Republic

If you’re a “US Person” (US citizen, permanent resident, or tax resident via Substantial Presence) and have bank accounts in Dominican Republic 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 Dominican Republic

If your Dominican Republic 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.

See: FATCA complete guide

US + Dominican Republic dual nationality

Dominican Republic allows dual nationality with US. If you naturalize as US citizen, you keep Dominican nationality (verify Dominican Republic’s current rules).

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 Dominican Republic on income generated in Dominican Republic
  • The US foreign tax credit (Form 1116) can reduce double taxation on income that Dominican Republic also taxes

Currency and conversion

Dominican Republic: DOP (Peso dominicano). When reporting Dominican 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)
