For international Miami buyers, income-tax residence and estate-tax domicile require separate reviews. Travel patterns, personal ties and ownership structure each matter, while directly owned U.S. real estate can create estate-tax exposure even for an owner who lives abroad.
For an international buyer, choosing a Miami residence involves more than deciding how much of the year to spend there. Two distinct federal tax questions frame the purchase: Where are you resident for income tax, and where are you domiciled for estate tax? The answers need not match.
That distinction matters whether the search centers on The Residences at 1428 Brickell or a home elsewhere in South Florida. A seasonal calendar does not, by itself, establish the owner's estate-tax position. Nor does remaining domiciled abroad eliminate potential estate-tax exposure from directly owned U.S. real estate.
The sound approach is to document both analyses before selecting an ownership structure, then revisit them as travel, family circumstances and intended use evolve. The residence should serve the family's life, with its tax consequences understood rather than assumed.
The substantial presence test generally requires at least 31 days in the United States during the current year and 183 weighted days across three years. The calculation includes:
All U.S. presence days in the current year.
One-third of U.S. presence days in the preceding year.
One-sixth of U.S. presence days in the second preceding year.
Any part of a day generally counts, subject to specified exceptions and exclusions. Travel records therefore require more precision than a broad estimate of months spent in Miami.
The central misconception is that spending fewer than 183 actual days in the United States in the current year provides a complete safe harbor. It does not. Prior-year visits contribute to the weighted total, so a recurring seasonal pattern can produce a different result from a single-year count.
The consequences extend beyond the property itself. U.S. income-tax residents generally face taxation on worldwide income and may have foreign-account or foreign-asset reporting obligations. For a buyer with business interests and investments abroad, the residence analysis should encompass the broader financial picture, not merely the home's operating costs.
A buyer who meets the substantial presence test may qualify for the closer-connection exception, but eligibility is conditional. Generally, the individual must spend fewer than 183 actual days in the United States during the current year, maintain a foreign tax home throughout that year and demonstrate a closer connection to a foreign country.
The supporting facts extend well beyond a foreign mailing address. They include the location of the permanent home, family, personal belongings, business activities, social affiliations, driver's license and voting jurisdiction. Claiming the exception generally requires timely filing of Form 8840, even when no income-tax return is otherwise required. The exception is unavailable when an individual has applied, or taken specified steps to apply, for lawful permanent resident status.
For someone considering The Perigon Miami Beach as a seasonal home, the useful exercise is to compare intended use with the family's actual connections abroad. Miami Beach ownership alone does not resolve that question.
An applicable income-tax treaty may offer a separate route for resolving dual residence through treaty-specific tie-breakers. These commonly examine permanent home, center of vital interests, habitual abode and nationality. Treaty availability and terms require individual review.
For federal estate-tax purposes, a noncitizen's residence generally depends on domicile rather than the substantial-presence formula. Domicile turns on living in a place with no definite present intention of leaving. Intent matters, as do the surrounding circumstances that support or contradict it.
Relevant evidence can include homes, family and business relationships, immigration status, community ties and declarations about residence or intended permanence. A day-count spreadsheet is useful for income-tax planning, but it cannot substitute for this broader inquiry.
A family evaluating Four Seasons Residences Coconut Grove should therefore distinguish the purchase itself from the home's intended role. Is Coconut Grove a seasonal destination or a place the family intends to remain indefinitely? That question belongs in the estate-planning discussion, alongside the facts of everyday life.
Meeting or failing the substantial presence test does not, by itself, settle estate-tax domicile. Each conclusion needs its own documented rationale.
Even when a buyer remains a nonresident, noncitizen for estate-tax purposes, directly owned U.S. real estate is U.S.-situated property. A Miami home can therefore create estate-tax exposure despite its owner's continuing life abroad.
For a nonresident, noncitizen decedent, Form 706-NA is generally required when U.S.-situated assets at death, plus adjusted taxable gifts and any applicable gift-tax specific exemption, exceed $60,000.
That figure requires careful interpretation. It is an estate-tax return filing threshold, not the much larger exclusion potentially available to U.S. citizens or U.S.-domiciled residents. It should not be read as a universal calculation of the estate's eventual liability.
Nonresident, noncitizen estates generally receive a limited estate-tax credit, although an applicable estate-tax treaty may provide more favorable treatment. Income-tax treaty residence relief and estate-tax treaty relief are separate inquiries. A favorable answer under one framework should never be assumed to resolve the other.
An entity should not be treated as an automatic estate-tax shield. Shares of corporations organized under U.S. law are generally U.S.-situated assets, so placing a Miami property in a U.S. corporation does not necessarily remove exposure.
Lifetime transfers also require a separate analysis. A gift of U.S. real estate by a nonresident, noncitizen can be subject to U.S. gift tax. Transferring the home to family members is therefore not a simple substitute for estate planning.
Intended rental use adds another layer. A nonresident's Miami rental property can generate U.S. income-tax and withholding obligations. Whether rental income is treated as effectively connected income requires a separate review; that treatment should not be assumed from the existence of a lease alone.
Before committing to an ownership structure, bring tax counsel, estate-planning counsel and cross-border accounting advisers into the same discussion. Ask for separate conclusions on income-tax residence and estate-tax domicile, together with an assessment of U.S.-situated assets and any applicable treaty provisions.
Maintain a travel calendar and records supporting the family's actual connections: foreign homes, family arrangements, business activity and community ties. Review those records annually and whenever the intended use of the Miami residence changes. A longer stay, a shift in family life or steps toward permanent resident status may require renewed advice.
The objective is not simply fewer days or a different name on title. It is a coherent plan that considers the family's intentions, documented circumstances and ownership decisions together.

Begin a quiet conversationNo. They are separate tests, and a person can qualify as a U.S. resident under one framework but not the other.
It generally requires at least 31 current-year days and 183 weighted days. The total includes all current-year days, one-third of preceding-year days and one-sixth of second-preceding-year days.
Not necessarily. Days from the two preceding years contribute to the weighted substantial-presence calculation, so fewer than 183 actual current-year days is not a complete safe harbor.
It generally requires fewer than 183 actual current-year U.S. days, a foreign tax home throughout the year and a closer connection to a foreign country. Timely filing Form 8840 is generally required, and specified permanent-residency application steps can make the exception unavailable.
It generally turns on living in a place with no definite present intention of leaving. Homes, family and business relationships, immigration status, community ties and declarations can inform the analysis.
Yes. Directly owned U.S. real estate is U.S.-situated property for estate-tax purposes, even when its owner remains domiciled abroad.
It is generally the Form 706-NA filing threshold for a nonresident, noncitizen estate when U.S.-situated assets, adjusted taxable gifts and any applicable gift-tax specific exemption exceed that amount. It is not the larger exclusion potentially available to U.S. citizens or U.S.-domiciled residents.
No. Shares of corporations organized under U.S. law are generally U.S.-situated assets, so corporate ownership does not automatically remove exposure.
Yes. Gifts of U.S. real estate by a nonresident, noncitizen can be subject to U.S. gift tax and require a separate transfer-tax analysis.
No. Income-tax residence relief and estate-tax treaty relief are separate inquiries, each dependent on the applicable treaty and the individual's circumstances.
