## What Is Territorial Residency Under U.S. Tax Law?
For U.S. citizens or resident aliens living in a U.S. territory like Puerto Rico, the U.S. Virgin Islands (USVI), Guam, CNMI, or American Samoa, **becoming a bona fide resident** has critical implications. Publication 570 from IRS (2025) sets out three tests:
- Physically present for at least **183 days** during the tax year in the territory. ([irs.gov](https://www.irs.gov/individuals/international-taxpayers/individuals-living-or-working-in-a-us-territory?utm_source=openai))
- Tax home is **inside** that territory. ([irs.gov](https://www.irs.gov/individuals/international-taxpayers/individuals-living-or-working-in-a-us-territory?utm_source=openai))
- Do not have a closer connection to the U.S. mainland or another foreign country. ([irs.gov](https://www.irs.gov/individuals/international-taxpayers/individuals-living-or-working-in-a-us-territory?utm_source=openai))
Meeting these means you may only owe tax on income from outside the territory, or exclude territory-source income from U.S. filings — depending on your situation.
## Why This Matters: Tax Implications for Gain, Credits, and Filing
Here are key implications:
| Scenario | Outcome if Bona Fide Resident | What If Not Resident? |
|---|---|---|
| Income from Puerto Rico | Taxed by Puerto Rico, excluded or partially excluded from U.S. return | Fully subject to U.S. federal tax |
| Accessing credits like the Additional Child Tax Credit (ACTC) in Puerto Rico | May be eligible with **one or more** qualifying child — threshold reduced ([irs.gov](https://www.irs.gov/publications/p570?utm_source=openai)) | Must meet standard U.S. credit rules |
| Net Investment Income Tax (NIIT) | May apply only to non-territorial income for bona fide residents ([irs.gov](https://www.irs.gov/publications/p570?utm_source=openai)) | Applies based on entire U.S. modified adjusted gross income |
| Filing Form 8898 | Required when becoming or ceasing bona fide residence if income > US$75,000 ([irs.gov](https://www.irs.gov/businesses/moving-to-or-from-a-united-states-us-territorypossession?utm_source=openai)) | Not needed if you remain resident consistently |
## Example: Moving to Puerto Rico Mid-Year
Imagine Maria, a U.S. citizen, moves to San Juan on May 1, 2025. She sells U.S. stock and earns U.S.-source dividends of US$30,000. She intends to live through the rest of the year in Puerto Rico, has her home there, and severs outside U.S. connections.
If she meets the bona fide residence tests:
- Her **Puerto Rico source income** is taxed locally.
- Her **U.S. dividend income** could be excluded from her U.S. return or taxed differently.
- She can claim ACTC if she has at least one qualifying child.
- She’d file **Form 8898** for 2025, since her worldwide income likely exceeds US$75,000 when adding other income.
If she fails one test — e.g., doesn’t stay 183 days — she remains treated as a regular U.S. taxpayer, liable on worldwide income.
## Practical Tips to Ensure Bona Fide Status
- Keep detailed **travel logs** to prove presence
- Move your **tax home** (banking, housing, employment) to the territory
- Sever connections (voting, driver license, family ties) with the U.S. mainland
- Ensure both U.S. and territory tax filings comply, especially with **Form 8898**
- Consult a local tax advisor: rules differ in Puerto Rico, USVI, CNMI etc.
## Key Takeaways
- Bona fide residence in a U.S. territory brings valuable benefits and exclusions under U.S. tax law.
- The rules are strict, so planning and documentation matter.
- Filing requirements like Form 8898 are essential when you change status.
**By following these steps and maintaining clarity**, U.S.-based taxpayers living in Caribbean territories can maximize tax efficiency and compliance. This discipline is especially important for digital nomads, retirees, investment income earners, or anyone straddling jurisdictions.
