An agreement between countries that says an expatriate only pays social taxes to the country in which he or she is working is called what?

• A. totalization agreement
• B. double taxation agreement
• C. social security treaty
• D. tax equalization

Answer: (A)

This concept focuses on how countries coordinate social security when someone works abroad. An agreement that makes an expatriate pay social security taxes to only the country where they’re employed is designed to avoid double contributions and to ensure the worker’s benefit credits count toward a single system. This is precisely what a totalization agreement does: it designates which country’s social security system applies and prevents paying into both, which can otherwise happen when someone is posted internationally. Double taxation agreements deal with income taxes, not social security taxes, so they’re addressing a different kind of tax burden. A social security treaty is another way people describe these arrangements, but the term most commonly used for this specific setup—where social security contributions are confined to the host country—is totalization. Tax equalization is a policy tool employers use to manage overall tax liability for international assignments and isn’t about which country collects social security taxes.
