Online Certificate of Coverage Service
Are you a U.S. employer with operations in other foreign countries? Do you send employees to work temporarily overseas? If so, you and your employees may benefit from the bilateral Social Security agreements the United States has concluded with certain foreign countries.
These agreements, often called "Totalization" agreements, eliminate dual Social Security taxation, the situation that occurs when an employee from one country works in another country and is required to pay Social Security taxes to both countries on the same earnings. The agreements assign coverage to just one country and exempt the employer and employee from the payment of Social Security taxes in the other country.
What are certificates of coverage?
If a Social Security agreement assigns coverage of the employee's work to the United States, the Social Security Administration issues a U.S. Certificate of Coverage. The certificate serves as proof that the employee and employer are exempt from the payment of Social Security taxes to the foreign country.
U.S. employers have traditionally used regular mail and fax to request certificates of coverage for their expatriate employees. Now, employers and self-employed individuals can request certificates on line.
