Cuba Cross-Border Tax Guide 2026

Overview — Cross-Border Taxation in Cuba

Cuba's cross-border tax environment is unique due to the interaction of domestic tax law, limited treaty coverage, and the impact of US economic sanctions under the embargo (Helms-Burton Act). Foreign investors typically access the Cuban market through joint ventures with state enterprises, international economic associations, or operations in the Mariel Special Development Zone. The ONAT administers cross-border tax rules under Law 113/2012. Cuba is not a member of the OECD BEPS Inclusive Framework but has adopted some transfer pricing concepts. The country has a limited network of double tax treaties that primarily benefit investors from treaty partner countries.

Withholding Taxes to Non-Residents

Payments to non-residents from Cuban sources are subject to withholding tax at the following standard rates (treaty rates may reduce these):

• Dividends — 15% on gross dividends paid to non-resident shareholders
• Interest — 10% on interest paid to non-residents (reduced to 5–7.5% under applicable treaties)
• Royalties — 10% on royalties and technical service fees paid to non-residents
• Management fees — 10% on management and administrative service fees
• Branch profits — 15% on profits remitted by a Cuban branch to its foreign head office
• Rental income — 10% on rental payments to non-resident property owners

The payer must withhold the tax and remit it to ONAT within 15 days of payment. Treaty relief requires the non-resident to provide a Certificate of Tax Residency from their home country and submit a treaty relief application to ONAT.

Double Tax Treaties

Cuba has a limited double tax treaty network. As of 2026, comprehensive DTTs are in force with:

• Spain — most important treaty for European investors; 7.5% dividend rate, 5% interest, reduced royalty rates
• China — covers business profits, dividends (7.5%), interest (5%), royalties (7.5%)
• Russia — comprehensive treaty covering all income types
• Vietnam — comprehensive coverage including capital gains
• Venezuela — limited treaty provisions

Treaties generally follow the OECD Model Convention. For investors from non-treaty countries, the full statutory withholding tax rates apply. Cuba has expressed interest in expanding its treaty network but progress has been slow.

Mariel Special Development Zone (ZED Mariel)

The Mariel SEZ offers the most attractive cross-border tax regime in Cuba. Key incentives for foreign investors establishing operations in the zone include:

• CIT rate — 10% standard (5% for high-tech/strategic projects) vs 35% outside the zone
• Exemption from profit distribution tax — 0% withholding on dividends/profit distributions
• Exemption from Sales and Services Tax — for goods and services within the zone
• Customs duty exemption — on imports of machinery, equipment, raw materials, and intermediate goods
• Labour tax incentives — reduced payroll tax rates
• Tax stability guarantee — benefits locked in for the duration of the investment contract (10–15 years)
• Accelerated depreciation — for fixed assets used within the zone

The Mariel Zone is administered by the ZED Mariel Office (OZD) and includes port, industrial, and logistics facilities. Over 50 foreign enterprises from 20 countries have established operations in the zone.

US Sanctions Considerations

US economic sanctions under the Cuban embargo (Trading with the Enemy Act, Helms-Burton Act) significantly impact cross-border transactions involving Cuba. Key considerations include:

• US persons and companies are generally prohibited from engaging in transactions with Cuba unless specifically licenced by OFAC
• Non-US companies with US operations or US-dollar transactions may be affected by sanctions
• US sanctions do not generally prohibit non-US companies from trading with Cuba, but compliance with US sanctions regimes is advised
• Banking transactions involving Cuba face enhanced due diligence and may be subject to US jurisdiction
• OFAC licences are available for certain categories (e.g., telecommunications, agricultural sales, remittances)
• The Helms-Burton Act Title III claims may affect investors using property nationalised by the Cuban government

FAQs

Do I need to register for tax in Cuba as a non-resident investor?

Non-residents earning Cuban-source income generally do not need to register if the income is subject to final withholding tax. However, a non-resident with a permanent establishment in Cuba must register and file corporate tax returns.

Can foreign companies claim reduced withholding tax rates?

Yes, if the foreign company is a tax resident of a country that has a double tax treaty with Cuba. The company must provide a Certificate of Tax Residency and submit a treaty relief application to ONAT.

Does Cuba have any tax information exchange agreements?

Cuba has limited TIEAs. It is not a member of the Global Forum on Transparency and Exchange of Information for Tax Purposes. Information exchange is primarily through bilateral treaties.
