Two Genuinely Useful Tools
Taiwan's progressive resident rates (5-40%) mean both the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC) do real work here, unlike a zero-tax Gulf posting where the FTC has nothing to offset. Which one wins depends primarily on where your income sits relative to Taiwan's brackets.
Qualifying for the FEIE: Two Tests
Physical Presence Test: 330 full days outside the US in any 12-month period.
Bona Fide Residence Test: An uninterrupted full tax year of Taiwanese residency, easier to satisfy once settled on an ARC (including via a Gold Card) with a lease and ongoing presence.
Where the Crossover Happens
Taiwan's brackets climb to 20% relatively early (above roughly NT$1,380,000, about $45,000 USD), then to 30% and 40% at higher levels. Once your effective Taiwan tax rate approaches or exceeds comparable US rates, typically for salaries well above $100,000, the Foreign Tax Credit starts producing a better result: it has no dollar cap, unlike the FEIE's $132,900 limit, and carries forward unused credits for up to ten years.
The Gold Card's 50% Deduction Complicates the Math
Qualifying Gold Card holders receive a 50% local tax deduction for three years, meaningfully lowering their effective Taiwan rate during that window. This can shift the FEIE-vs-FTC crossover point higher during the deduction period, and shift it back down once the three years expire, worth modeling both scenarios if you're on a Gold Card.
