Tax equalization is a policy applied by some international companies under which employees who are hired in one country and later accept a (temporary) assignment in another country do not have their total after-tax ("take-home") compensation changed depending on the tax regimes of the country they move to.
Some multinational corporations implement a policy called "tax equalization" that ensures employees' total take-home pay remains consistent regardless of where they are assigned for temporary work. This policy applies when an employee is hired in one country and then moves to another country for a short-term assignment.
