Most people are familiar with tax treaties – like the one that exists between the U.S. and Canada. But did you know the U.S. and Canada also has a social security treaty? It’s called a Totalization Agreement. It protects the benefit rights of workers that divide their career between Canada and the U.S. It also helps to avoid situations where workers and their employers are required to pay social tax in two countries on the same earnings. In short, this agreement helps to eliminate dual social security coverage and taxation. Plus, the worker usually gets to maintain coverage in the country they will have the greatest attachment.
So, if heading to the U.S., but only for a short time, consider getting a Certificate of Coverage. This may allow you to be exempt from U.S. Social Security Tax (FICA), if covered by the Canada-U.S. Social Security Agreement.
