The United States stands virtually alone in the world with its unique approach to taxation, and dual income taxes in the USA apply to residents regardless of where they live or earn their money. While most countries only tax residents on income earned within their borders, America taxes its citizens on worldwide income, creating complex scenarios for digital nomads who earn money across multiple jurisdictions. This distinctive system means that US citizens working remotely from Thailand, freelancing in Portugal, or running businesses in Mexico must still file US tax returns and potentially pay US taxes on their global earnings.
Understanding dual income taxes in the USA becomes crucial for digital nomads who face potential taxation in both their country of residence and the United States. This comprehensive guide explores how America’s citizenship-based taxation system works, the tools available to minimize double taxation, and the strategic planning required to remain compliant while maximizing your financial efficiency as a location-independent professional.
Understanding America’s unique taxation system
The United States operates on a citizenship-based taxation model, making dual income taxes in the USA a reality for American digital nomads worldwide. Unlike territorial tax systems used by most countries, the US requires citizens to report and potentially pay taxes on all income, regardless of geographic source or residence location.
Most countries employ territorial taxation, taxing only income earned within their borders. However, the US and Eritrea are the only two nations that tax citizens based on citizenship rather than residence. This creates unique challenges for location-independent professionals who must file US tax returns and potentially owe US taxes even when living permanently abroad.
💡 Did you know? The US citizenship-based tax system dates back to the Civil War era, when the government needed to ensure tax revenue from citizens living abroad. Unlike most wartime measures, this system remained in place and expanded over time.
While citizenship determines tax obligations for Americans, non-citizens can also face dual income taxes in the USA through residency tests. The Substantial Presence Test considers individuals to be US tax residents if they spend 31+ days in the current year and 183+ weighted days over three years in the United States.
🌟 Pro tip: track your US presence carefully using the weighted formula: current year days count as full days, prior year days count as 1/3, and second prior year days count as 1/6. This calculation determines your US tax residency status.
The foreign earned income exclusion: primary relief for dual taxation
The Foreign Earned Income Exclusion (FEIE) provides the most significant relief from dual income taxes in the USA for qualifying digital nomads. This provision allows eligible taxpayers to exclude up to $112,000 (2022 amount, adjusted annually) of foreign-earned income from US taxation.
To claim the FEIE, taxpayers must meet either the bona fide residence test or the physical presence test. The physical presence test demands 330+ days outside the US during any 12-month period, while bona fide residence requires establishing genuine residence in a foreign country for an uninterrupted tax year.
While the FEIE significantly reduces dual income taxes in the USA, it comes with important limitations. The exclusion only applies to earned income and doesn’t cover passive income like investments or rental income. Additionally, excluded income cannot be contributed to US retirement accounts.
💡 Did you know? Choosing to use the FEIE is actually an election that binds you for future years. Revoking the election requires IRS approval and prevents you from claiming it again for five years without permission.
The Foreign Housing Exclusion provides additional relief for qualifying taxpayers, allowing exclusion of certain housing expenses above a base amount. High-cost locations like London or Tokyo offer substantial housing exclusions, while lower-cost areas provide minimal benefits.
🌟 Pro tip: maintain reliable internet connectivity while managing complex international tax obligations. A robust US data connection ensures you stay connected with tax professionals and can access necessary financial platforms from anywhere in the world.
Foreign tax credits and tax treaty benefits
Foreign Tax Credits (FTC) provide an alternative approach to managing dual income taxes in the USA, allowing taxpayers to credit foreign taxes paid against US tax liability. Unlike the FEIE, which excludes income from taxation, the FTC reduces US taxes dollar-for-dollar for qualifying foreign taxes paid.
The choice between FTC and FEIE significantly impacts tax planning. FTC generally benefits taxpayers in high-tax foreign countries, while FEIE suits those in low-tax jurisdictions. FTC allows contributions to US retirement accounts since income isn’t excluded, making it attractive for long-term financial planning.
Foreign tax credits cannot exceed US tax liability on foreign income, and excess credits can be carried back one year or forward ten years. Different types of foreign taxes qualify for credit, including income taxes and similar levies.
💡 Did you know? Some countries have “tax sparing” provisions in their treaties with the US, allowing credits for taxes that would have been paid in the foreign country if not for special incentives or exemptions.
US tax treaties provide additional mechanisms for managing dual income taxes in the USA, though they rarely override citizenship-based taxation entirely. The “saving clause” in most US treaties preserves the US right to tax its citizens on worldwide income, limiting treaty benefits for Americans.
For individuals who meet residency tests in multiple countries, tax treaties provide tie-breaker rules to determine primary tax residence. These rules examine factors like permanent home location and center of vital interests to resolve dual residency conflicts.
Compliance requirements and strategic planning
Dual income taxes in the USA create extensive reporting requirements beyond standard tax returns. American digital nomads face additional forms, including the Foreign Bank Account Report (FBAR) for accounts exceeding $10,000 and Form 8938 for foreign financial assets above certain thresholds.
FBAR violations carry severe penalties, including criminal charges for willful non-compliance. Form 8938 files with tax returns and has higher reporting thresholds for foreign residents. The Foreign Account Tax Compliance Act (FATCA) requires foreign financial institutions to report US account holders, making compliance increasingly important.
💡 Did you know? The IRS offers penalty relief programs for taxpayers who voluntarily come forward to correct past non-compliance with foreign account reporting requirements, though the terms vary based on circumstances.
Effective management requires proactive planning and professional guidance. Strategic income timing can optimize exclusions and credits, while business structure decisions significantly impact tax implications. Digital nomads can sometimes shift income between tax years to maximize FEIE benefits or coordinate with foreign tax obligations.
Traditional retirement account contributions become complex under dual taxation rules. FEIE users cannot contribute excluded income to US retirement accounts, while FTC users maintain contribution eligibility. Some foreign pension plans receive favorable US tax treatment under treaties.
🌟 Pro tip: maintain detailed records of travel dates, income sources, foreign taxes paid, and housing expenses. This documentation proves essential for substantiating claims and surviving potential IRS scrutiny.
Final thoughts
Navigating dual income taxes in the USA represents one of the most complex aspects of American digital nomadism, but understanding the system and available relief mechanisms makes compliance manageable and optimization possible. The combination of the Foreign Earned Income Exclusion, Foreign Tax Credits, and strategic planning can significantly reduce the burden of citizenship-based taxation while maintaining full compliance with US tax law.
Success requires staying informed about changing regulations, maintaining meticulous records, and working with qualified tax professionals who understand both US international tax law and the realities of nomadic life. While the complexity may seem daunting, proper planning and professional guidance can help you minimize dual taxation while maximizing the freedom and opportunities that come with location-independent work.

Frequently asked questions about dual income taxes in the USA
Yes, US citizens must file tax returns regardless of where they live or how long they’ve been abroad. The US taxes citizens on worldwide income, though exclusions and credits may eliminate actual tax liability. This obligation continues until you renounce citizenship or meet very specific expatriation requirements.
No, you cannot claim both FEIE and Foreign Tax Credits on the same income. However, you can use FEIE on some income and FTC on other income within the same tax year. Many high earners use FEIE up to the exclusion limit and FTC for excess income to optimize their overall tax burden.
Failing the physical presence test by even one day disqualifies you from claiming FEIE for that entire year. There are limited exceptions for certain circumstances beyond your control, such as war or civil unrest, but these are narrowly applied and require substantial documentation to qualify.
State tax obligations depend on your state of legal residence, not your physical location while traveling. Some states like Florida and Texas have no income tax, while others like California, may continue taxing former residents on certain income types. Establishing residency in a no-tax state before going nomadic can provide significant savings.
FBAR penalties can reach $12,921 per account per year for non-willful violations, with much higher penalties for willful violations that can exceed the account balance. Form 8938 penalties start at $10,000 and can reach $60,000 for continued failures to file after IRS notices.
