Panama Makes Foreign-Source Income Tax Exemption Conditional on Genuine Economic Substance in the Country

Mario Arias · Founding Partner

FOR DECADES, Panama's tax system has rested on a simple principle: income generated outside the country is not subject to taxation in Panama. This principle, known as territorial taxation, underpins many of the investment, wealth-holding, and financing structures established in Panama to operate internationally.

Law 526 of May 28, 2026, does not eliminate this principle. It makes it conditional. Beginning with the 2027 tax year, certain Panamanian entities will retain the exemption on their foreign-source income only if they can demonstrate that genuine economic activity supports their structures in Panama. Those that cannot will be subject to a 15% tax on the net amount of such income.

Who Is Affected

The regime does not apply to every Panamanian entity, a distinction worth emphasizing given the considerable confusion surrounding the legislation in recent months.

Three conditions must be met simultaneously: the entity must be incorporated or domiciled in Panama, it must belong to a multinational group, and it must receive foreign-source passive income, namely dividends, interest, royalties, capital gains, or income from real estate located abroad. If any one of these conditions is absent, the regime does not apply.

The second condition is particularly significant, and its scope may come as a surprise.

For purposes of the law, a multinational group consists of two or more entities connected through ownership or control that are tax residents in different jurisdictions. There is no minimum threshold for size or revenue.

If your structure includes a Panamanian entity and at least one related entity abroad, this condition is satisfied, regardless of scale. A private interest foundation that controls a foreign company meets the definition. So does a Panamanian holding company with interests in operating businesses in Colombia or Spain.

What Constitutes Genuine Economic Substance

Where the regime applies, an entity must demonstrate three elements within Panama: qualified and remunerated personnel responsible for managing the income-generating assets, together with adequate premises; strategic decisions concerning those activities being made in Panama; and the incurrence of local operating expenses.

The law does not prescribe a minimum number of employees or a minimum level of expenditure. Instead, adequacy is assessed proportionately, taking into account the nature, scale, and complexity of the operations, as well as the amount of income generated.

Activities may be outsourced to a local service provider, provided they are physically performed in Panama. Outsourcing activities abroad does not count toward meeting the substance requirements.

There is an important concession for some of the most common structures.

Entities whose principal activity consists of holding equity interests in other entities or owning real estate are subject to a simplified substance test. They need only satisfy the first requirement — adequate personnel and premises — together with the annual reporting obligation.

The obligation to file a tax return does not depend on the issuance of implementing regulations and applies even to entities that satisfy the substance requirements. Every entity belonging to a multinational group that receives foreign-source passive income must file an income tax return, even if that is its only income and even if it has never previously filed a tax return in Panama.

The Pending Implementing Regulations

Much of the regime's framework is already established in the legislation itself: its scope, the categories of income covered, the 15% tax rate on net income, the simplified substance test, the exclusions for regulated financial and insurance entities and the merchant marine sector, and the foreign tax credit.

What remains outstanding are the operational parameters.

The law granted the Executive Branch ninety days to issue its implementing regulations. That deadline expired on August 26, and the corresponding decree has yet to be published.

Its absence does not suspend the regime. The new rules take effect beginning with the 2027 tax year, and the first tax return will be due in March 2028.

What the delay does is shorten the time available to prepare. Hiring personnel, entering into lease agreements, or effectively relocating strategic decision-making to Panama are measures that can take months to implement.

Among Panamanian legal and tax practitioners, the debate has centered on an issue with significant implications for estate and wealth planning: whether private interest foundations and other succession-planning vehicles fall within the definition of a multinational group.

Those advocating for their exclusion argue that these vehicles are fundamentally different in nature from companies forming part of multinational business groups.

The argument has merit, but the statutory language does not expressly support that distinction. The law defines the relevant relationship by reference to ownership or control and tax residency, without differentiating entities according to their legal nature or purpose.

If an exclusion is ultimately introduced, it will have to come through the implementing regulations.

And those regulations must reconcile two objectives that pull in different directions: avoiding the unintended inclusion of structures the legislation was not designed to capture, while preserving the underlying purpose of the reform, which responds to commitments made to the OECD and the European Union. The latter is scheduled to review its list of non-cooperative tax jurisdictions in October.

Planning today on the assumption that such an exclusion will be adopted is a gamble.

What Should Be Done Now

Two important steps can be taken without waiting for the implementing regulations.

The first is to determine whether the regime applies.

Establishing whether a second related entity exists outside Panama is a binary determination that shapes the entire analysis.

If no such entity exists, the regime does not apply, and the analysis ends there.

If one does exist, the next step is to identify the types of income received by the Panamanian entity, because economic substance is assessed by income category and tax year, rather than simply at the entity level.

The second is to organize existing supporting documentation.

Many structures have more genuine economic activity than their records demonstrate: decisions actually made in Panama without minutes documenting them, or local expenditures lacking adequate accounting records.

Compiling this evidence does not require knowing the final parameters of the implementing decree and can significantly reduce the work required later.

What should be avoided is creating artificial economic substance.

The law authorizes Panama's Ministry of Economy and Finance to disregard arrangements whose principal purpose is to obtain a tax advantage without valid commercial reasons.

A rushed compliance exercise unsupported by genuine economic activity is precisely the type of arrangement this provision is intended to address.
