For U.S. citizens and residents in Cuba, U.S. tax compliance is complicated by the absence of both a bilateral income tax treaty and a social security agreement. Double taxation is primarily managed through U.S. domestic provisions like the Foreign Tax Credit and the Foreign Earned Income Exclusion. This page provides neutral, informational content on U.S. tax obligations and does not constitute tax advice or an offer of service.
US filing basics every American abroad must know
US citizens and green-card holders are taxed on worldwide income wherever they live, and usually must file Form 1040 once gross income exceeds the IRS threshold ($15,750 for single filers, $31,500 for married filing jointly, and $23,625 for head of household for 2025), even when no tax is ultimately due. The tools that reduce double taxation are the Foreign Earned Income Exclusion (FEIE, up to $130,000 for 2025 under IRC §911) and the Foreign Tax Credit. Neither is automatic. The FEIE requires a tax home in a foreign country plus either the bona fide residence test or 330 full days abroad in a 12-month period, and it reaches earned income only. The Foreign Tax Credit is figured separately for each income category under IRC §904 and is capped at the US tax on the foreign income in that category, so it reduces double taxation without guaranteeing that none remains.
Two reporting rules catch most filers in Cuba: the FBAR (FinCEN Form 114), required when foreign financial accounts exceed $10,000 in aggregate at any point in the year, and Form 8938 (FATCA) for specified foreign assets above the applicable threshold. Both can carry penalties even when no tax is owed. If you are behind, the Streamlined Filing Compliance Procedures are the usual path back for non-willful taxpayers. They run on two tracks: the foreign track carries no offshore penalty but requires meeting the program's non-residency test, and the domestic track carries a 5% offshore penalty but works through amended returns, so it does not fit someone who never filed at all. Tax and interest on the catch-up years are owed whichever route applies.
US tax treaty with Cuba
There is no income tax treaty between the United States and Cuba. Consequently, there are no treaty-based reductions in withholding tax rates, and no special rules for resolving dual residency or reallocating taxing rights. U.S. taxpayers in Cuba must rely on the Foreign Tax Credit (FTC) to offset Cuban income taxes against their U.S. tax liability, or the Foreign Earned Income Exclusion (FEIE) to exclude wages and self-employment income from U.S. tax, subject to statutory limits.
Cuban Social Security and US Tax
Cuba's main retirement system is the Régimen General de Seguridad Social, a state-run social security program funded by employer and employee contributions. Self-employed individuals, known as cuentapropistas, are required to contribute to a parallel special regime.
For U.S. tax purposes, the treatment is as follows:
- Contributions: Payments made by a U.S. person into the Cuban social security system are generally not deductible on a U.S. tax return.
- Benefits: In the absence of a tax treaty, social security benefits received from the Cuban system are generally considered taxable income by the IRS and must be reported on Form 1040. It is also important to note that U.S. Treasury Department regulations prohibit the Social Security Administration from sending U.S. social security payments to individuals residing in Cuba.
- U.S. Reporting: State-run social security systems do not trigger foreign trust or PFIC reporting, though private foreign pensions might.
Investments, property, and capital gains in Cuba
U.S. persons with investments or property in Cuba face several complex U.S. tax reporting requirements. Any investment in a Cuban pooled fund, similar to a foreign mutual fund, is likely a Passive Foreign Investment Company (PFIC). This requires the U.S. investor to file Form 8621 annually for each PFIC, and without specific elections, income and gains from the fund are subject to a punitive default tax and interest charge regime.
Regarding capital gains, Cuba does not have a separate capital gains tax; gains are often taxed as ordinary income. The U.S., however, taxes the worldwide capital gains of its citizens. The sale of an asset in Cuba, such as real estate, will produce a capital gain or loss reportable on the U.S. return, calculated under U.S. rules. A transfer tax is not creditable against U.S. tax, but it reduces the capital gain realized on the sale.
Ownership in a Cuban business entity, such as a joint venture (empresa mixta) or a private small or medium-sized enterprise (MIPYME), often structured as a limited liability company (Sociedad de Responsabilidad Limitada), triggers significant U.S. reporting. The entity is a Controlled Foreign Corporation (CFC) when U.S. shareholders who each own 10% or more hold, in the aggregate, more than 50% of it by vote or by value. This requires the U.S. shareholder to file Form 5471 annually. Furthermore, as a CFC shareholder, the U.S. person may have to pay U.S. tax on their share of the company's earnings under the Global Intangible Low-Taxed Income (GILTI) and Subpart F regimes, even if no profits are distributed. An entity classification election on Form 8832 (a 'check-the-box' election) may be available to treat the entity as a partnership or disregarded entity, which changes the U.S. tax and reporting consequences.
Finally, all foreign financial assets must be disclosed. This includes filing a FinCEN Form 114, FBAR, if the total value of all foreign financial accounts exceeds $10,000, and potentially Form 8938 if asset value thresholds are met.
Self-employment and companies in Cuba
A critical point for self-employed U.S. citizens in Cuba (often known as cuentapropistas) is the complete absence of a U.S.-Cuba social security agreement, also known as a totalization agreement. This has a significant financial consequence: the U.S. person is subject to U.S. self-employment tax on their net earnings from self-employment once those earnings are $400 or more.
For the 2025 tax year, this tax is 15.3% on 92.35% of net earnings from self-employment. The 12.4% Social Security portion stops at the annual wage base ($176,100 for 2025), but the 2.9% Medicare portion applies to all of the base amount, plus a further 0.9% Additional Medicare Tax on combined Medicare-taxed wages and self-employment income above $200,000 for a single, head-of-household or qualifying-surviving-spouse filer, $250,000 for a joint return, and $125,000 for married filing separately. The Foreign Earned Income Exclusion (FEIE) cannot be used to reduce income subject to self-employment tax. A U.S. person cannot obtain a Certificate of Coverage from either country to claim an exemption. As Cuba also requires self-employed individuals to contribute to its own social security system, this results in mandatory payments into both systems on the same income, a situation of true double social security taxation.
Worked examples
Manager for a foreign-owned joint venture in Havana (2025)
An American manager for a foreign joint venture in Havana earns a salary of $60,000. Because there is no tax treaty, double taxation is managed through U.S. law. If the manager's tax home is in Cuba, they are present in Cuba without violating U.S. travel restrictions, and they meet either the 330-day physical presence test or the bona fide residence test, the Foreign Earned Income Exclusion (FEIE) can exclude this salary from U.S. income tax up to the 2025 limit of $130,000, which would leave no U.S. income tax on the salary. Alternatively, they could use the Foreign Tax Credit (FTC) to credit Cuban income taxes paid against their U.S. tax liability. Regardless of which method is used, the individual must still file a U.S. tax return. They must also report their Cuban bank accounts on an FBAR if the aggregate balance exceeds $10,000 at any point during the year and may need to file Form 8938.
Self-employed photographer and tour guide in Trinidad (2025)
A U.S. citizen works as a self-employed photographer (cuentapropista) and has net earnings of $45,000 for the year. While the Foreign Earned Income Exclusion can remove U.S. income tax on this amount, assuming they qualify for it (see the travel-restriction rule below), the FEIE does not affect U.S. self-employment tax. Because there is no U.S.-Cuba totalization agreement, they owe full U.S. self-employment tax. The calculation is on 92.35% of their net earnings: $45,000 * 0.9235 = $41,557.50. The tax is 15.3% of this amount, resulting in a U.S. self-employment tax liability of $6,358.30. This is owed to the IRS in addition to any mandatory social security contributions they must make in Cuba.
U.S. resident partner in a Cuban private enterprise (MIPYME) (2025)
A U.S. resident owns 60% of a Cuban MIPYME, which is a limited liability company. A company is a Controlled Foreign Corporation (CFC) when U.S. shareholders who each own 10% or more hold, in the aggregate, more than 50% by vote or by value, and a single 60% U.S. owner meets that test here. The U.S. owner must file Form 5471, an extensive information return. Even if the company retains all its profits and pays no dividends, the U.S. owner may have a current U.S. tax liability on their share of the company’s earnings under the GILTI (Global Intangible Low-Taxed Income) rules. For example, if the company earned $50,000 and the owner’s pro-rata share is $30,000, a portion of that $30,000 could be immediately taxable as ordinary income on their U.S. return. This reporting and tax liability exists regardless of U.S. sanctions on Cuba.
Common mistakes for Americans in Cuba
- Assuming a U.S.-Cuba tax treaty exists to reduce taxes or provide relief.
- Believing that a totalization agreement is in place and that U.S. self-employment tax can be avoided by paying into the Cuban system.
- Using the Foreign Earned Income Exclusion to try to reduce or eliminate U.S. self-employment tax, which it does not do.
- Failing to file Form 5471 for an ownership interest in a Cuban company (like a MIPYME), which can lead to significant penalties.
- Ignoring the potential for current U.S. taxation on undistributed profits from a Cuban company under the GILTI and Subpart F rules.
- Forgetting to file an FBAR (FinCEN Form 114) for Cuban bank or financial accounts, mistakenly believing sanctions remove this requirement.
- Treating Cuban social security benefits as non-taxable in the U.S., when they are generally reportable income.
- Overlooking the complex PFIC rules (Form 8621) for any investments in Cuban pooled funds.
Cuba tax FAQ
Is there a U.S.-Cuba tax treaty?
No. There is no income tax treaty in force between the United States and Cuba. U.S. taxpayers cannot claim any treaty benefits, such as reduced withholding rates or specific rules for pension taxation. Double tax relief relies on U.S. domestic law, like the Foreign Tax Credit and Foreign Earned Income Exclusion.
Do I have to pay U.S. Social Security and Medicare taxes if I'm self-employed in Cuba?
Yes. There is no social security totalization agreement between the U.S. and Cuba. A self-employed U.S. citizen in Cuba with net earnings from self-employment of $400 or more is required to pay U.S. self-employment tax at 15.3% on 92.35% of those net earnings, with the 12.4% Social Security portion stopping at the annual wage base ($176,100 for 2025) and the 2.9% Medicare portion uncapped, in addition to any mandatory social security contributions required by Cuba. The Foreign Earned Income Exclusion does not reduce this tax.
Are my Cuban bank accounts reportable to the U.S. government?
Yes. U.S. citizens and residents are required to report their worldwide financial accounts. If the combined value of your foreign accounts, including those in Cuba, exceeds $10,000 at any time during the year, you must file a FinCEN Form 114 (FBAR). Depending on the total value of your foreign assets, you may also need to file IRS Form 8938.
How are benefits from Cuba's social security system taxed in the U.S.?
Absent a tax treaty providing an exemption, foreign social security benefits are generally taxable in the United States. Payments received from the Cuban Régimen General de Seguridad Social should be reported as income on your U.S. tax return, Form 1040.
What are the U.S. tax implications of owning a share in a Cuban private business (MIPYME)?
If you are a U.S. person and your ownership stake in a Cuban company (like a MIPYME) is 10% or more, and U.S. shareholders each owning 10% or more together hold more than 50% of the company by vote or by value, the company is a Controlled Foreign Corporation (CFC). This requires you to file Form 5471 annually. You may also be taxed currently in the U.S. on your share of the company's profits under the GILTI rules, even if you receive no distributions.
Can I use the Foreign Earned Income Exclusion (FEIE) while living in Cuba?
Only if three conditions are met. Your tax home must be in a foreign country, you must meet either the bona fide residence test or the 330-day physical presence test, and you must not have been in Cuba in violation of U.S. travel restrictions. The Form 2555 instructions single Cuba out: if you were there in violation of the travel restrictions, that time cannot be counted toward either test, income earned in Cuba is not treated as foreign earned income, and Cuban housing costs are not qualified housing expenses. It is also important to remember that the FEIE only applies to earned income (wages and self-employment income) and does not exclude passive income like interest, dividends, or capital gains. It also does not reduce U.S. self-employment tax.
Do U.S. sanctions against Cuba change my U.S. tax filing obligations?
No. U.S. sanctions administered by the Office of Foreign Assets Control (OFAC) restrict many transactions and activities with Cuba, but they do not alter a U.S. person's obligation to file U.S. tax returns and report their worldwide income. The requirement to file tax returns, FBARs, and other international information forms remains fully in effect.
What is a PFIC and how does it relate to Cuba?
A PFIC is a Passive Foreign Investment Company, which is a foreign corporation with significant passive income or assets. An investment in a Cuban pooled investment fund would likely be considered a PFIC. Owning a PFIC requires filing Form 8621 and can lead to very high U.S. tax rates on distributions and gains unless you make timely elections.
