Every country earns its place in the model.

Retiring abroad is not a spreadsheet row with a cheaper rent number. Each country has its own income tax, its own tax-treaty rules, its own inheritance law, health system, and currency. So here is the build sheet. It shows what we model, what does not apply, and what is still open.

A check mark only appears when the engine does the work.

Modeled

This tax is computed in your projection. The number is real.

Does not apply

The tax does not exist or does not reach a US retiree there. Not a gap.

What is modeled, country by country.

Not a gap. Genuinely does not apply.

A dash means the tax does not reach a US retiree in that country. It shows for one of three reasons:

  • The country only taxes locally earned income (a territorial system), so your US-source income is not taxed there.
  • The tax does not exist.
  • The exemption threshold clears virtually every retirement plan.
