Preferential Tax Regimes for Expats and Global Investors

Many countries offer preferential tax regimes to attract foreign investment, wealthy individuals, and skilled professionals.

These regimes provide reduced tax rates or exemptions for certain types of income, such as pensions, foreign dividends, or passive investment earnings.

For globally mobile individuals, expats, retirees, digital nomads, and business owners, these tax benefits can significantly reduce their total tax burden.

However, preferential tax regimes are complex. They are legal in many jurisdictions but must comply with international standards to avoid being labeled as harmful or abusive.

Understanding how these regimes work, which countries offer them, and what qualifies as eligible income is essential before considering a move or restructuring your financial affairs.

What is a preferential tax regime?

A preferential tax regime refers to a tax framework within a country that offers lower tax rates or special tax benefits to certain types of taxpayers, income, or activities, typically to attract foreign investment, high-net-worth individuals, or specialized workers.

These regimes differ from the country’s general tax system and are often limited to specific income sources or groups.

Preferential tax regimes are not the same as tax havens. While tax havens generally impose little to no taxes on all residents or companies and often lack transparency, preferential tax regimes operate within countries that otherwise have normal or high tax rates.

These regimes apply selective tax advantages under structured programs and are usually part of a broader economic strategy.

For example:

• Italy used to offer a flat €100,000 annual tax (€200,000 now) on foreign income for qualifying high-net-worth individuals, but applies normal tax rates to others.
• Portugal’s former NHR (Non-Habitual Resident) regime taxed most foreign-source income at 0–10%, while domestic income remained taxed at progressive rates.

These regimes are often compliant with international standards but may still face scrutiny depending on how they are structured and monitored.

How Preferential Tax Treatment Works

What are preferential tax rates?

Preferential tax rates are reduced income tax rates applied to specific types of income, individuals, or economic activities. They may take the form of:

• Flat-rate taxes (e.g. 15% on certain foreign income)
• Full or partial tax exemptions (e.g. zero tax on dividends or pensions)
• Time-limited benefits (e.g. reduced rates for 5–10 years after relocating)

These rates are generally lower than the country’s standard progressive rates, which can exceed 40% in many developed nations.

What income receives preferential tax rates?

Common types of income that may receive preferential treatment include:

• Foreign-source income (e.g. overseas dividends, capital gains, or rental income)
• Pensions and retirement income
• Royalties or intellectual property income
• Passive investment income such as dividends and interest
• Income from designated professions (e.g. tech, finance, academia)

In many cases, only income earned outside the host country qualifies for reduced tax rates. Domestic income usually remains fully taxable.

What qualifies for preferential tax treatment?

Eligibility typically depends on:

• Tax residency status (you must meet residency criteria)
• Nationality or previous residence (some regimes exclude citizens or recent residents)
• Economic contribution (e.g. property investment, job creation, or minimum income)
• Time limits (some benefits are only available for a set number of years)

Each country sets its own requirements, and qualifying often requires formal registration or application with local tax authorities.

Are preferential tax regimes legal under international law?

Yes. Preferential tax regimes are legal as long as they comply with international standards on transparency, information exchange, and anti-avoidance rules.

Many developed countries, including members of the OECD and EU, operate such regimes within legal frameworks designed to attract certain types of residents or economic activity.

What becomes problematic is when a regime is deemed harmful, i.e., when it:

• Offers benefits without requiring substantial economic activity or residency
• Lacks transparency
• Prevents effective exchange of information with other tax authorities
• Encourages profit shifting or erosion of other countries’ tax bases

To remain legal and internationally accepted, countries must ensure their regimes are not designed for secrecy or tax evasion and that they allow for automatic exchange of information, such as through the OECD’s Common Reporting Standard (CRS).

How does the OECD monitor preferential tax regimes?

The OECD Forum on Harmful Tax Practices (FHTP) evaluates preferential regimes using a framework agreed upon by member countries and participants in the Inclusive Framework on BEPS (Base Erosion and Profit Shifting).

The key assessment criteria include:

• Substantial Activity Requirement: Does the regime require real economic activity in the jurisdiction?
• Transparency: Are the rules clear, and can other countries access relevant tax information?
• No Ring-Fencing: Is the regime only available to foreigners or offshore income while excluding local residents or businesses?
• Effective Exchange of Information: Does the country share tax data with other jurisdictions?

If a regime fails these tests, the OECD may label it as “harmful”, triggering pressure for reform and possible inclusion on blacklists by the EU or other bodies. Countries often revise or eliminate these regimes to avoid reputational damage and regulatory consequences.

Preferential Tax Regime Countries

Here are notable examples of countries with preferential tax regimes:

• Portugal (formerly NHR program): Offered a 10-year tax exemption on most foreign-source income. As of 2024, the program has been replaced with more limited benefits for specific professions.
• Italy: As of August 2024, the annual flat tax for new applicants has been increased from €100,000 to €200,000. Existing participants in the program are still subject to the original €100,000 rate.
• Greece: Greece’s tax regime for foreign retirees offers a 7% flat tax rate on all foreign-sourced income, including pensions, for up to 15 years.
• Cyprus: Allows tax exemptions for foreign pensions and investment income, and has a non-domicile rule that exempts many forms of passive income from tax.
• Malta: Provides favorable tax treatment under its Global Residence and Retirement Programmes, including exemptions for certain foreign income.
• United Arab Emirates: Has no personal income tax. Recent treaty networks and residency visa reforms have made it more accessible to long-term residents seeking tax neutrality.
• Thailand: Its Long-Term Resident (LTR) visa offers tax benefits to retirees, professionals, and investors under specific conditions.
• Panama: Uses a territorial tax system only local income is taxed. Foreign-source income is exempt regardless of residency.

These regimes are typically limited in scope and duration, and may focus on foreign-source income, pensions, or specific professions.

While these regimes vary, they generally require:

• Proof of residency or long-term stay
• Minimum income or asset levels
• Application to the tax authority or relevant government program

Each regime has specific eligibility rules, reporting requirements, and limitations. It’s essential to assess whether the scope of tax benefits aligns with your income sources and long-term plans.

Should I move to a preferential tax regime country?

Relocating for tax benefits can be financially advantageous, but it involves significant trade-offs and legal considerations. You should only consider moving if:

• You understand how your income will be taxed globally
• You can legally sever tax residency from your home country (if needed)
• You meet all eligibility and compliance requirements in the destination country
• The lifestyle, healthcare, and visa conditions meet your long-term needs

It is not a guaranteed path to lower taxes, especially if your income structure is complex or your home country retains taxing rights.

Before making a decision, it is advised to consult an international tax advisor with knowledge of both countries, a relocation or immigration expert, or your trusted financial planner, if applicable.

In short, preferential tax regimes can be useful tools, but only within a well-structured, legally compliant plan.
