What is a totalization agreement and how does it help me qualify?

A totalization agreement is a treaty between the U.S. and another country that lets you combine your work credits from both countries to qualify for benefits, and prevents you from paying Social Security taxes to both systems on the same earnings. If you split a career between, say, the U.S. and Germany and fall short of the 40 credits needed in either country alone, the agreement lets each country count the other's coverage to determine eligibility — though each country pays only for the portion of work done under its own system. The U.S. has agreements with around 30 countries, mostly in Europe plus Canada, Japan, South Korea, and Australia; notably, the U.S. does not yet have one with India. If you have worked abroad, request your foreign coverage record and check whether an agreement applies before assuming you fall short of qualifying.
