Why a UAE Tax-Residency Certificate Means Nothing Without Emirati Citizenship

Moving to Dubai Won’t Save You from Warsaw:

Polish entrepreneurs and workers relocating to Dubai assume that a residence visa and physical presence in the Emirates automatically shield them from the Polish tax authorities. Recent rulings from Warsaw suggest otherwise—and the bill can amount to full taxation on worldwide income.

The Trap Buried in Article 4

The tax treaty between Poland and the United Arab Emirates—signed in Abu Dhabi in 1993 and amended by a protocol that entered into force on May 1, 2015—contains a provision whose consequences most people moving to the Gulf never pause to consider. Under the revised Article 4(1)(b)(i), a natural person qualifies as a resident of the UAE for treaty purposes only if that person both resides in the Emirates and holds Emirati citizenship.

That second requirement is the one that does the damage. The original 1993 text referred simply to a person “liable to tax” in the UAE on the basis of domicile, permanent residence, or similar criteria—boilerplate language drawn from the OECD Model Convention. The 2013 protocol replaced it with an explicit citizenship test, and Emirati citizenship is, to put it mildly, not easily come by. Roughly eighty per cent of the UAE’s population consists of foreign nationals who have no realistic path to naturalization, regardless of how long they live and work in the country. A 2015 ruling by the Director of the Tax Chamber in Katowice put it plainly: citizenship “is granted only to persons born in the UAE of Arab descent and is held by approximately 20% of the population.”

Two Rulings, Two Outcomes

The practical consequences of this rule emerge most vividly in a pair of individual tax interpretations issued by Poland’s Director of National Tax Information within two months of each other, both involving Polish citizens working in the UAE.

When the Family Stays Behind

In a ruling dated February 21, 2024 (case number 0114-KDIP3-2.4011.957.2023.3.JK2), a Polish national had left for the Emirates in January 2023. He took a permanent position with a UAE-based employer, rented an apartment in Dubai, obtained a residence visa and an Emirates Resident ID, bought a car, opened a local bank account. He spent more than a hundred and eighty-three days in the UAE; his professional, social, and cultural life was centered there.

His wife and two young children, however, remained in Poland.

The tax authority’s conclusion was swift and unforgiving. The applicant’s center of economic interests was, without question, in the UAE. But his center of personal interests—defined by family ties, the domestic hearth—remained in Poland. Under Article 3(1a) of the Polish Personal Income Tax Act, a person is deemed a Polish tax resident if they maintain in Poland their center of personal interests or economic interests. The disjunctive “or” is the operative word: satisfying either prong is sufficient.

The authority went further. It noted that holding a UAE residence visa is not the same as being recognized as a UAE tax resident under the treaty. Without Emirati citizenship, the applicant did not meet the definition in Article 4(1)(b)(i), which meant that the treaty’s tie-breaker rules—permanent home, center of vital interests, habitual abode, nationality—never came into play. There was no dual residency to break.

The result: full Polish tax liability on worldwide income for 2023, with the obligation to report UAE earnings in his Polish return and apply the proportional-credit method under Article 27(9) of the PIT Act. Since the Emirates levy no personal income tax, the credit is zero. The effective rate is Poland’s.

When the Family Comes Along

The ruling of December 27, 2023 (case number 0114-KDIP3-2.4011.938.2023.1.JK3) tells a different story—or, more precisely, the same story with a different second act. This applicant left Poland in March 2023. By mid-April, his wife and young son had joined him in the UAE. He, too, lacked Emirati citizenship. He, too, had no tax-identification number in the Emirates and no certificate of tax residency issued by a UAE authority. Under UAE law, he was not subject to income tax—because there was no income tax to be subject to.

Yet the tax authority reached the opposite conclusion. From the moment the family arrived, both the applicant’s personal and economic centers of interest were in the Emirates. He no longer met either prong of Article 3(1a). From mid-April 2023 onward, he was a Polish non-resident, liable to tax in Poland only on income sourced within its borders.

Between January and mid-April—when he was already physically in the UAE but his wife and child had not yet left Poland—he remained a full Polish tax resident. The authority drew the line not at his departure, but at his family’s.

The Asymmetry the Treaty Creates

Placing the two rulings side by side reveals a mechanism that is both elegant in its logic and brutal in its consequences.

The Poland-UAE treaty’s tie-breaker provisions apply only when the same individual qualifies as a tax resident of both countries. A Polish citizen without an Emirati passport cannot satisfy the treaty’s definition of a UAE resident. The result is a structural asymmetry: Poland claims the taxpayer as its own (because he maintains personal ties there), and the treaty offers no countervailing claim from the Emirates’ side. The cascading tests of Article 4(3)—permanent home, vital interests, habitual abode, nationality—are designed to resolve conflicts between two competing residency claims. Where only one claim exists, there is nothing to resolve.

This means that the only path to losing Polish tax residency runs through Polish domestic law alone. The treaty is irrelevant. The certificate is irrelevant. Emirati citizenship is irrelevant. What matters is whether the conditions of Article 3(1a) of the PIT Act continue to be met.

Four Conditions for a Clean Break

The two rulings, read together, yield a practical checklist—a set of conditions that, if satisfied, will persuade the Polish tax authorities that residency has been genuinely relinquished.

First, move the family. Leaving a spouse and children in Poland almost automatically preserves the center of personal interests in the country, regardless of how thoroughly the taxpayer has established economic life abroad.

Second, sever economic ties with Poland. No active business, no employment, no board seats in Polish entities, no significant real property or vehicles. Portfolio investments—brokerage accounts, retirement savings, shares in limited-liability companies—do not necessarily prevent a change of residency, but they should be managed remotely, and the taxpayer’s obligations in the UAE should significantly outweigh those in Poland.

Third, build genuine substance in the UAE. A rental agreement, local bank accounts, health insurance, a life-insurance policy, a driver’s license, vehicle registration, social and cultural engagement—these elements, taken together, construct the picture of a life transplanted rather than merely duplicated.

Fourth, limit time in Poland. While this is a separate, independent basis for residency—more than a hundred and eighty-three days triggers it on its own—avoiding extended stays in Poland eliminates the second statutory ground.

The Third-Country Alternative

The fact that the Poland-UAE treaty fails to protect individuals without Emirati citizenship does not mean that treaty protection is unavailable altogether.

If a Polish citizen establishes tax residency in a third country—one that has concluded a double-taxation agreement with Poland based on the standard OECD model, without a citizenship requirement—then the taxpayer loses Polish residency under domestic law (by relocating the center of vital interests), gains treaty protection under the agreement with the third country, and can subsequently relocate physically to the UAE while maintaining formal residency in the third jurisdiction.

This requires careful planning and analysis of specific treaty networks, but it addresses the structural gap that the citizenship requirement in the Poland-UAE treaty creates.

The Bottom Line

A move to Dubai does not automatically protect against Polish taxation. The Poland-UAE tax treaty requires Emirati citizenship for a natural person to be recognized as a UAE resident—a residence visa and physical presence are insufficient. Without treaty-resident status, the tie-breaker rules do not apply, and protection can be achieved only through the effective elimination of both statutory grounds for Polish residency under domestic law. Leaving a family behind in Poland is, in the eyes of the tax authorities, dispositive.

Every relocation to the Emirates should be preceded by an analysis of the individual’s circumstances under both Polish domestic law and the treaty framework—ideally before the departure, not after it.
