Banking when you live in one country and earn in another

The structure most residents end up with

Almost everyone converges on the same arrangement after a year: the home-country account stays open for income and investments, a local account handles rent and utilities, and a multi-currency account sits between them doing the conversion.

Trying to run everything from a home-country card works for a holiday and fails for a life — foreign transaction fees and rate margins compound quietly.

Opening the local account

Local banks generally require a tax number and proof of address, which puts the account after residency in the sequence. Some countries allow a limited-function account earlier; ask at a branch rather than online, where the answer is usually a flat no.

The transfer margin is the real cost

A retail bank commonly takes two to four per cent on the exchange rate in addition to a wire fee. On regular transfers that is the largest recurring cost of living abroad that nobody budgets for.

A word about tax

Residency for immigration purposes and residency for tax purposes are different tests with different thresholds, and holding accounts in two countries can create reporting obligations in both. This is the one area where paying a professional early is unambiguously cheaper than not.
