For the United States, the agreement applies to the Retirement, Survivors, Disability (RSDI) program, Federal Insurance Contributions Act (FICA) taxes for employment, and Self-Employment Contributions Act (SECA) taxes for self-employment, including the Medicare portion. Thus, if an employee is exempt from U.S. Social Security coverage under this agreement, neither the employee nor the employer has to pay his or her share of the FICA tax as long as the exemption is effective. A self-employed person is also exempt from paying the SECA taxes (equivalent to the employee and employer share of the FICA tax) for any period the exemption is effective.

For Brazil, the agreement applies to the laws governing old-age, survivors, and disability benefits insurance programs of two branches of the social security system: the General Regime of Social Security (RGPS) and the Regime of Social Security of Public Servants (RPPS). Consequently, if a worker is exempt from Brazilian coverage because of the agreement, no contributions are due for these programs.
