Understanding the difference

The Safety Net Divide

US taxes fund Social Security, Medicare, and disability insurance; you're buying a social safety net that covers healthcare and retirement. Vietnam's contributions are lower but narrower, funding only insurance basics without the broader welfare cushion Americans expect.

California's Hidden Cost

The US number gets inflated by California's aggressive state income tax, which climbs to 13.3% at high earns. Vietnam has no regional taxes at all, making the total burden more predictable and geographically uniform.

Who Actually Wins

Lower earners win in Vietnam, period. The 5% base rate and high personal allowance mean modest incomes stay mostly untouched. Higher earners in the US get squeezed harder by California and Medicare surcharges, but they're also buying decades of documented social benefits.

The Expat Reality Check

If you're earning US wages in Vietnam, you're potentially liable in both countries. Vietnam taxes residents on worldwide income; the US does too. Careful tax planning matters here, and it's rarely reflected in raw numbers.
