IRA Contributions for U.S. Expats: How FEIE and FTC Really Work (And Why It Matters for Your Retirement)
For U.S. citizens living abroad, managing taxes and saving for retirement often go hand in hand. While Individual Retirement Accounts (IRAs) remain one of the most effective tools for long-term wealth building, many expats are surprised to learn that certain expat tax benefits can limit their ability to contribute. Two provisions of the U.S. tax code — the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC) — play a central role in determining whether foreign income can be used for IRA contributions.
Although both FEIE and FTC are designed to prevent double taxation, they operate very differently. The choice between them can influence not only your current tax bill, but also your long-term retirement outcomes. Understanding how these rules interact is essential for U.S. expats who want to balance tax efficiency today with financial security tomorrow.
Why IRA Contributions Are Different for Americans Living Abroad
IRAs are popular because they allow investments to grow either tax-deferred or tax-free, depending on whether you use a Traditional or Roth IRA. For expats who may not have access to U.S.-based employer retirement plans, IRAs often become the foundation of retirement savings. However, the IRS imposes a key requirement that can complicate matters for Americans overseas: you must have taxable earned income to make an IRA contribution.
Earned income generally includes wages, salaries, bonuses, commissions, and self-employment income. Passive income such as interest, dividends, capital gains, rental income, pensions, and Social Security benefits does not qualify. More importantly for expats, income that is excluded from U.S. taxation is not considered taxable earned income for IRA purposes. This is where FEIE and FTC begin to matter.
How the Foreign Earned Income Exclusion Works
The Foreign Earned Income Exclusion allows qualifying U.S. expats to exclude a portion of their foreign earned income from U.S. income tax. To qualify, you must have a tax home outside the United States and meet either the Physical Presence Test or the Bona Fide Residence Test. For 2026, the exclusion allows up to $132,900 of foreign earned income to be removed from U.S. taxation, with the amount adjusted annually for inflation.
FEIE can be especially attractive for Americans living in low-tax or no-tax countries, as it often eliminates U.S. federal income tax entirely. From a short-term cash-flow perspective, FEIE can feel like an obvious choice. However, excluded income is treated by the IRS as if it never existed for tax purposes. While that reduces your tax bill, it also removes that income from consideration as compensation for retirement contributions.
When all of your earned income is excluded under FEIE, your U.S. tax return may show zero taxable earned income. In that case, you are not eligible to contribute to a Traditional or Roth IRA, even though you may have earned a substantial salary abroad. This outcome often catches expats by surprise and can quietly derail long-term retirement planning.
The Foreign Tax Credit as an Alternative
The Foreign Tax Credit takes a fundamentally different approach. Instead of excluding income from U.S. taxation, the FTC allows you to offset U.S. tax liability with income taxes paid to a foreign government. Your foreign income remains fully reported on your U.S. tax return, and U.S. tax is calculated as usual. You then apply credits for qualifying foreign taxes, often reducing your U.S. tax liability to zero.
Because income claimed under the FTC is still included in taxable income, it continues to qualify as earned income for IRA purposes. This distinction is critical. Many expats living in higher-tax countries find that the FTC not only eliminates double taxation, but also preserves their ability to save for retirement through IRAs.
From a planning perspective, FTC is often more aligned with long-term wealth building, even if it requires more detailed reporting and coordination with foreign tax systems.
The Retirement Trade-Off Between FEIE and FTC
Choosing between FEIE and FTC is not simply a matter of minimizing taxes in the current year. It is a strategic decision that can influence retirement savings, Roth IRA eligibility, and future flexibility. FEIE tends to favor immediate tax reduction, particularly in low-tax jurisdictions. FTC tends to favor long-term planning by preserving taxable income that can be used for retirement contributions.
For some expats, a hybrid approach may be available. If your foreign earned income exceeds the FEIE limit, you may be able to exclude part of your income under FEIE while using FTC on the remainder. This can create a portion of taxable earned income, potentially allowing limited IRA contributions. However, these calculations can be complex, and mistakes may lead to excess contributions and IRS penalties.
Roth IRA Considerations for U.S. Expats
Roth IRAs are especially appealing to expats because qualified withdrawals are tax-free in America, there are no required minimum distributions, and they can be advantageous for estate planning. However, Roth IRA contribution eligibility depends on Modified Adjusted Gross Income (MAGI), and FEIE complicates this calculation.
Although FEIE reduces taxable income, the IRS adds excluded income back when calculating MAGI for Roth IRA eligibility. This means that an expat may appear to earn too much to qualify for a Roth IRA even if their U.S. taxable income is very low. In contrast, using the FTC often produces a clearer picture for Roth planning, since income is fully reported and credits are applied afterward.
The Five-Year FEIE Rule and Long-Term Planning
Another important technical consideration is the five-year rule associated with FEIE. If you choose to revoke FEIE, the IRS generally prevents you from claiming it again for five years unless you receive special permission. This rule makes switching between FEIE and FTC a decision that should be evaluated carefully. What looks like a small tax optimization today can limit flexibility for years to come.
Because expat careers, residency, and tax environments change over time, planning decisions should account for future scenarios, and your lifetime tax plan, rather than focusing solely on the current tax year.
Foreign Tax Treatment of IRAs
U.S. tax rules are only one side of the equation. Many countries do not recognize IRAs as tax-deferred retirement accounts. Some tax IRA growth annually, while others tax distributions in ways that differ significantly from U.S. treatment. Many countries also won’t recognise the tax-free treatment of the Roth IRA, and will tax expats on any gains above their cost basis, something most Americans don’t track with their Roth IRA accounts, unfortunately. Without proper planning, this can lead to double taxation and reduced retirement outcomes.
Understanding how your country of residence treats IRAs is just as important as understanding U.S. tax rules. In some cases, alternative investment structures may be more efficient depending on your long-term residency plans.
Common Pitfalls for U.S. Expats
Many expats assume that FEIE is always the best option, contribute to IRAs without qualifying earned income, or fail to coordinate tax strategy with retirement planning. Others focus only on reducing taxes today without considering how those decisions affect retirement savings over decades. These mistakes are rarely intentional, but they can be costly over time.
Aligning Tax Strategy With Retirement Goals
Effective expat financial planning requires coordination between tax strategy, retirement planning, and cross-border considerations. The optimal approach depends on income level, country of residence, tax rates, expected length of time abroad, and long-term retirement goals. There is no universal solution, but informed decisions can significantly improve outcomes.
For many U.S. expats, taxes are temporary, but retirement is permanent. Choosing between FEIE and FTC should not be based solely on which option produces the lowest tax bill this year. Instead, it should be evaluated in the context of long-term wealth accumulation, retirement flexibility, and financial security.
Final Thoughts
The Foreign Earned Income Exclusion and the Foreign Tax Credit are powerful tools for U.S. citizens living abroad, but they come with trade-offs that are often overlooked. While FEIE can dramatically reduce current taxes, it may also limit your ability to save in tax-advantaged retirement accounts. FTC, although more complex, often supports stronger long-term retirement planning.
Understanding these interactions is essential for expats who want to make informed decisions about their financial future.
