Turkey is selling tax holidays. The question is whether anyone will believe them

TÜRKİYE IS NOT selling sunshine and a lower cost of living. It is selling something more unusual in the 21st century: a long tax holiday, a wealth amnesty and an invitation to park foreign income without a bill for two decades. On June 4th the law entered into force, published in the Official Gazette. What had been President Erdoğan's ambitious April proposal is now statute.

The headline mechanism is a 20-year exemption from Turkish income tax on foreign-sourced earnings for people who relocate and have not been domiciled or tax-liable in Turkey for the preceding three years. It is paired with a flat 1% inheritance and gift tax, down from the standard rate that can reach 30%. A separate asset-repatriation amnesty lets individuals and companies declare money, gold, foreign currency and securities held abroad, bringing them into Turkish banks by July 2027. The declared assets are taxed at 5% - or 0%, if the money stays in eligible Turkish financial instruments for five years.

To be sure, this is not unprecedented. Panama has taxed only domestic income for decades. Portugal once offered a 10-year non-habitual resident scheme. Dubai charges no personal income tax at all. What distinguishes Turkey's package is its duration, its breadth and the fact that it comes from a country of 85 million people that is still managing an inflation rate above 30%. The timing, moreover, is not accidental.

The incentive points in one direction. The UK abolished its non-domiciled tax regime on April 6th 2025, removing a long-standing magnet for globally mobile wealth. UBS, a bank, projects Britain will lose approximately 500,000 millionaires by 2028, falling from 3.06m to 2.54m. An estimated 16,500 high-net-worth individuals departed the UK last year, taking with them roughly $92 billion in investable assets. Those numbers are the largest annual outflow from any country. Dubai, unsurprisingly, is the primary beneficiary: it is forecast to welcome around 9,800 inbound millionaires this year. Record numbers - 165,000 millionaires globally - are projected to relocate in 2026, up from 142,000 last year, says Janus Hermes, a research outfit.

Turkey is positioning itself as an alternative for those who do not want to end up in the desert, or who want a foot on two continents. The citizenship-by-investment programme, which has existed since 2016, already allows a passport for a property purchase of at least $400,000. The new tax regime makes that passport more useful. Together they form a coherent package: buy property, establish residency, keep your foreign income tax-free for two decades, bring your offshore savings into Turkey at a discount.

The trouble is that this is a bargain with strings. Turkish-source income is taxed at the usual progressive rates of 15% to 40%. Costs linked to exempt foreign income cannot be deducted against taxable domestic income. And the residency test, though its exact threshold awaits secondary regulations, will almost certainly require a real commitment to living in Turkey, not merely a bank account. For Americans, the offer is largely illusory: the United States taxes citizens on worldwide income regardless of where they live, and a zero-tax destination provides no foreign tax credit to offset the IRS's claim. For everyone else, the arithmetic is straightforward.

Yet the deeper problem is not who qualifies. It is why Turkey is making this offer. The answer is a combination of genuine reform and fiscal desperation. Inflation, though it has eased from its 49.4% peak in September 2024 to around 32% today, is still punishing. The lira has spent most of the past decade losing ground against the dollar. Foreign investment has been scarce and fickle. The IMF noted in its February 2026 Article IV consultation that lira demand has strengthened, but the country remains vulnerable. Turkey needs foreign capital urgently. It is prepared to pay for it with tax receipts it will not collect for a very long time.

That raises two structural risks. The first is one of credibility. A 20-year horizon is extraordinarily long for a developing economy with a political system that is increasingly concentrated. The ruling Justice and Development Party dominates parliament and the executive; the president can extend the asset amnesty's declaration window by six-month increments. For the wealthy investor, the question is not merely whether the tax break exists today but whether the same government - or its successor - will honour it in year 14. Portugal's non-habitual resident regime was curtailed earlier than many expected. Italy's flat-tax programme for new residents is already being tightened. Long tax holidays have a habit of ending when they are inconvenient.

The second risk is more political. The Financial Times reported in late July that fears of a catastrophic post-non-dom exodus from the UK have been somewhat exaggerated. The replacement regime - a four-year "foreign income and gains" window - still benefits roughly 14,800 former non-doms, down from 73,700. The wealthy do not always vote with their feet; they often vote with their accountants. Turkey's amnesty, by contrast, is designed precisely for people whose wealth has been hidden. Opposition lawmakers have already warned that repeated asset amnesties weaken tax compliance and risk letting money of unclear origin enter the financial system with limited scrutiny. A think-tank article from the Middle East Institute, published shortly after the proposal, argued that the scheme could deepen Turkey's exposure to money laundering and sanctions evasion. The law says anti-money-laundering obligations are not suspended, but in practice the burden falls on banks and the Financial Crimes Investigation Board to apply source-of-funds controls rigorously. Whether they will is an open question.

This is not to say the package is a scam. It contains genuine incentives for legitimate foreign investors and entrepreneurs. The corporate tax rate for manufacturing has been cut from 25% to 12.5%. The Istanbul Finance Centre - Turkey's answer to London and Dubai's financial districts - gets a 100% corporate tax deduction on financial-services exports extended until 2047. Venture-capital funds are now eligible instruments for the asset amnesty, suggesting an attempt to channel some of the repatriated capital into innovation rather than term deposits. For a founder or entrepreneur from Russia, the Middle East, or Asia, the offer is not unattractive.

The real question is what Turkey gets in return for the deal it has struck. The immediate answer is foreign currency flowing into banks, some property purchases and a modest boost to Istanbul's real-estate market. The longer-term answer depends on whether the people who move also bring productive activity - jobs, technology, consumption - or merely a tax-optimised bank balance. If the latter, Turkey will have traded two decades of foreign-income tax for a temporary injection of capital that could leave just as quickly.

For the UK, the lesson is uncomfortable. Abolishing the non-dom regime was politically popular; the Chancellor faced a Tory backbench that wanted to see wealthy foreigners pay their fair share. But the decision contributed to a climate of punitive taxation that pushed capital elsewhere. The replacement four-year FIG regime is narrower and less generous. Britain cannot compete on raw tax rates with the UAE or, now, Turkey. Its advantage - legal predictability, deep financial infrastructure, global connectivity - matters less when the marginal rate of taxation looks confiscatory and the political signal looks hostile. The damage to Britain's brand as a financial centre may be slower than the headlines suggested, but it is real.

A wiser approach for both Britain and Turkey would be different. Britain should restore some predictability and avoid the temptation to introduce wealth taxes, which are historically the most distortionary form of taxation. Turkey should make its amnesty work for its own economy, not just for expatriates. That means ensuring the repatriated assets flow into productive investment, not passive holdings. It means building a financial-services ecosystem in Istanbul that can actually compete, not just offer tax breaks. And it means maintaining the political stability that makes a 20-year promise look like more than a gamble.

The scramble for mobile wealth is not new. What is new is its speed. Governments that raise taxes in one corner of the world create opportunities in another. Turkey has seized them. Whether the country can convert a tax holiday into lasting prosperity, rather than a brief accounting illusion, is the question the rest of the system will answer.
