Foreign Earned Income Simulator
U.S. taxpayers living abroad must report their worldwide income. Simulate whether the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit (FTC) is more advantageous for you.
FEIE vs. FTC: Strategy Calculator
The chart visually compares your U.S. 'taxable' income under each strategy.
FEIE vs. FTC: Key Comparison
| Criteria | Foreign Earned Income Exclusion (FEIE) | Foreign Tax Credit (FTC) |
|---|---|---|
| Best Use Case | Low/no-tax countries (e.g., UAE) | High-tax countries (e.g., Western Europe) |
| Applicable Income | Earned income only | Earned + Passive income (investments, etc.) |
| Self-Employment Tax Impact | No reduction | Can offset self-employment tax liability |
| Flexibility | Lost if not used in the current year | Unused credits can be carried forward 10 years |
Revoking an FEIE election may restrict re-election for 5 years, requiring a careful decision.

Health Account (HSA/FSA) Tax Savings Analysis
HSAs and FSAs are powerful tax-saving tools that can reduce both income tax and FICA taxes. Find the optimal strategy for you.
Is an HSA the Best Retirement Account?
Compare an HSA to a 401(k) directly from a retirement savings perspective.
An HSA offers tax benefits at all three stages: contribution, growth, and withdrawal (for medical expenses). The exemption from FICA taxes on payroll contributions gives it a stronger start than a 401(k).
