This is a complicated tax situation. Taxes on salary tend to be based on place of employment. So if you’re working for a US company you’ll need to look into what tax treaties your country of residence has with the US, because your US employer will likely have to withhold taxes and provide a W2. Your host country will ask that you report your income. If the treaty allows, you can claim tax paid in the US as a credit. The reverse is often true in these treaties.

This will often have consequences with things like pensions, Holiday pay, etc… For example, if your country has a lot of mandated vacation you may either not have that benefit, or your company will have to conform to the country’s rules which could cause friction, especially with American companies.
