Passing the Bona Fide Residency Test: The IRS Three-Part Rule Explained

Act 60 gives you the tax rate. Bona fide residency gives you the legal right to use it. The distinction is critical: you can hold an Act 60 decree and still owe full US federal taxes if you fail the IRS residency test. The decree is necessary but not sufficient.

The IRS applies a three-part test under IRC Section 937 to determine whether you are a bona fide resident of Puerto Rico. All three parts must be satisfied simultaneously. Fail any one, and your Act 60 benefits are worthless for that tax year.

Test 1: Physical Presence — The 183-Day Rule

The simplest test to understand, and the easiest to track: you must be physically present in Puerto Rico for at least 183 days during the calendar year.

The corollary that trips people up: you cannot be present in the mainland United States for more than 182 days. These two limits work together — every day you spend in Puerto Rico is a day you are not spending in the mainland, and vice versa.

Strategic implication: plan your travel calendar before you move. Most successful decree holders treat Puerto Rico as their genuine home base and spend the majority of their time there. If your business or family obligations require frequent mainland travel, you need to track every day carefully and build in margin.

Test 2: Tax Home — Your Principal Place of Business

Your tax home must be in Puerto Rico. The IRS defines tax home as your regular or principal place of business, regardless of where you maintain your family residence.

For Chapter 3 Export Services decree holders, this is usually straightforward — your business serves non-PR clients, but you operate it from Puerto Rico. Your office, your employees (if any), and your business registration are all PR-based.

For Chapter 2 Individual Resident Investors, the tax home test can be more nuanced. If you are retired or living off investment income, your "tax home" is Puerto Rico because that is where you live and conduct your financial affairs. If you maintain a mainland business, you must restructure so that Puerto Rico is genuinely your principal place of business.

Test 3: Closer Connection — The 11 Factors

This is the most subjective and most heavily scrutinized test. The IRS evaluates whether you have a "closer connection" to Puerto Rico than to the United States or any other jurisdiction. They assess 11 factors, and no single factor is decisive — the totality of your circumstances matters.

The 11 Closer-Connection Factors

1. Location of permanent home: Where do you own or rent your primary residence? A owned home in Puerto Rico carries more weight than a rented apartment.
2. Location of family: Where does your spouse live? Where do your children attend school? Family location is one of the most heavily weighted factors.
3. Personal belongings: Where are your cars, furniture, art, and valuable personal property? Moving your household goods to Puerto Rico demonstrates commitment.
4. Driver's license and vehicle registration: A Puerto Rico driver's license and PR-registered vehicles are essential. Surrender your mainland license.
5. Voter registration: You should be registered to vote in Puerto Rico, not in a mainland state. (Note: US citizens can vote in federal elections only in their state of domicile — if PR is your domicile, you vote there.)
6. Banking relationships: Your primary checking, savings, and brokerage accounts should be at PR-based institutions or clearly PR-domiciled. Maintain PR utility accounts in your name.
7. Social and religious affiliations: Church membership, club memberships, professional associations, and social organizations in Puerto Rico strengthen your case.
8. Professional advisors: Your CPA, attorney, financial advisor, and insurance agent should be based in or clearly serving Puerto Rico.
9. Business activities: Where is your business headquartered? Where are your business bank accounts? Where are your professional licenses?
10. Political ties: Community involvement, charitable involvement, and civic engagement in Puerto Rico.
11. Time spent: Beyond the 183-day physical presence test, how do you spend your time? A person who is in Puerto Rico for 183 days but spends the other 182 days actively engaged in mainland business and social life will struggle with the closer-connection test.

The pattern across all 11 factors is the same: does your life actually center on Puerto Rico? The IRS is not looking for a checklist of technical compliance. They are looking for genuine relocation. A person who has moved their family, their belongings, their banking, their professional life, and their social network to Puerto Rico passes easily. A person who has maintained their mainland life and added a Puerto Rico address does not.

Documentation Checklist: Building an Audit-Proof Record

Keep this documentation organized and current. If you are audited — and Act 60 decree holders are audited more frequently than the average taxpayer — you will need to produce this evidence quickly. We help clients build this record from day one, not retroactively.

Common Mistakes That Fail the Test

• Splitting the year: Moving mid-year without understanding the partial-year residency rules. The first year requires special attention — see below.
• Keeping a mainland driver's license: This is the single most common failure point. If you are pulled over in Puerto Rico with a mainland license after claiming PR residency, your position is undermined.
• Mainland voter registration: Still registered to vote in New York or California? The IRS treats this as evidence of closer connection to that state.
• Family stays on the mainland: If your spouse and children remain in a mainland home while you live in Puerto Rico, the closer-connection test becomes very difficult to pass.
• Insufficient days: Counting travel days, partial days, or days spent in transit incorrectly. One miscounted month can fail the 183-day test.
• Mainland business operations: Running your business from a mainland office with occasional Puerto Rico visits. The tax home test fails.

The First-Year Partial Residency Exception

You do not have to move on January 1st. You can establish bona fide residency mid-year, and the IRS applies a special computation for your first partial year. Under this method:

• You must be present in Puerto Rico for at least 183 days during the portion of the year beginning with your move date and ending December 31.
• You cannot be present in the mainland for more than 182 days during that same period.
• You must satisfy the tax home and closer connection tests from your move date forward.

The benefit: your Act 60 decree benefits begin from your official residency date, not January 1 of the following year. Income earned after your residency date qualifies for Act 60 rates. Income earned before is taxed at mainland rates.

The risk: the first-year computation is more complex, and errors here are common. We strongly recommend professional guidance for the transition year — this is not the place to self-manage.

Key Takeaways

• All three tests must pass simultaneously: 183+ days in PR, tax home in PR, closer connection to PR.
• The 11 closer-connection factors examine whether your life genuinely centers on Puerto Rico.
• Surrender your mainland driver's license, voter registration, and shift your banking and professional life to PR.
• Maintain documentation from day one — not retroactively when audited.
• The first-year partial residency exception allows mid-year moves with special computation.
