Passport? Good.

Compared across countries

Can you get a tax refund on shopping?

For a trip that crosses borders — the same question, answered country by country.

The pattern

Three of the four refund the tax; the United States does not. Korea can take it off at the counter, Taiwan and Thailand make you claim at the airport before the bags are checked. In the US the tax is a state one and there is no federal scheme to claim against — Louisiana runs the only visitor refund in the country.

Sort the practical stuff before you fly.

eSIMs, rail passes, and airport transfers — the things worth booking before you land.
