Alternative	549 days / 3 years, minimal US ties
Additional requirements	Tax home, closer connection tests

Bona fide residence turns on 3 tests, and all of them have to hold together for the same tax year:

• Presence — time in the territory, or time away from the mainland. 5 routes satisfy it, listed below.
• Tax home — your main place of business or employment must be in the territory rather than outside it.
• Closer connection — your ties must not point more strongly to the mainland United States or to a foreign country than to the Virgin Islands.

Failing any one of the 3 breaks bona fide residence, however comfortably the others are met. That is the part people underestimate: a full year of presence achieves nothing if your work base and your family remain on the mainland.

The presence test is the one with options. Meeting any single route satisfies it:

• 183 days in the territory during the tax year — the ordinary route.
• 549 days across the tax year and the 2 before it, with at least 60 days in every one of those 3 years.
• 90 days or fewer in the mainland US during the tax year.
• Capped US-source earned income, alongside more days in the territory than in the mainland.
• No significant connection to the mainland US — no home, no voter registration, no spouse or minor child there.

The last 3 routes measure what you did away from the territory rather than inside it. That is why someone with a modest local day count can still pass presence, and why the test is far wider than the 183-day figure suggests.

The status matters because it decides where you file. A bona fide resident generally settles their liability with the territory's own revenue bureau rather than filing with both. It is also the gateway to the Virgin Islands economic development incentives, which are applied for separately and carry their own conditions.

• Presence without a tax home achieves nothing. Spending the full year in the territory while your main place of business stays on the mainland fails the second test and breaks bona fide residence.
• The 3-year alternative has a floor in every year. 549 days spread unevenly still fails if any of the 3 years falls below 60 days of presence.
• A capped-income route exists but is narrow. The US-source earned income limit is a low fixed figure, so it rarely helps anyone with meaningful mainland earnings, whatever their day counts look like.
• Moving mid-year has special treatment. The year you take up or give up residence is handled under rules for partial-year cases rather than the ordinary tests.
• Bona fide residence is not the same as the incentive programmes. The economic development benefits require a separate application with their own conditions, and residence alone does not grant them.
• US citizenship still reaches you. Being a bona fide resident changes where and how you file, but it does not remove US citizenship-based obligations.

Bona fide residence decides which authority you file with, so an error usually surfaces as a return filed in the wrong place and a dual-filing obligation you never met. The ordinary federal regime for late or understated returns then applies, with penalties on the tax owed and interest running from the original due date. Professional tax advice is strongly recommended in situations like this.

A clean year on all three tests

You move to St Thomas, work from an office there all year, and spend around 300 days in the territory with your family and home alongside you. Presence, tax home and closer connection all hold, so you are a bona fide resident.

Enough days, wrong tax home

You spend 250 days in the Virgin Islands but continue running your business from an office in Florida, flying back regularly. The presence test is met and the tax home test is not, so bona fide residence fails.

The three-year route with a thin year

Across 3 years you spend 549 days in the territory, but one of those years holds only 45. The aggregate is met and the 60-day floor in every year is not, so the alternative presence route is unavailable.
