U.S. issued certificate 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 online.

You may access the online Certificate of Coverage service at opts.ssa.gov. If you would like instructions or require assistance with the use of the online forms, please contact the Social Security Administration's Office of Earnings and International Operations by phone at (410) 965-7306, Monday through Friday, from 8 a.m. to 3 p.m. Eastern U.S. time.
