Suppose a worker born on January 2, 1951 applied for an old-age pension in January 2017. The worker worked in the United States for 8 years – from 1980 to 1987 – and earned the maximum amount of taxes subject to Social Security each year. As a result, the worker has accumulated 32 QCs, which is not enough to qualify for a superannuation only with U.S. coverage. However, this worker also covered in Switzerland. Since the United States and Switzerland have a totalization agreement and the worker has at least 6 QCs, it can be attributed to the worker`s Swiss coverage that he or she can benefit from a fully beneficiary benefit. The U.S. worker`s benefit is calculated in the steps described below. The overall average of reports (in this example an 8-year average) is called the relative position of merit, which corresponds to 2.2871073 for our hypothetical worker. This amount is then multiplied by the national average salary for each year over an entire career. This period begins from the year in which the worker has reached the age of 22 (in this case 1973) and ends in the year in which the worker has reached the age of 61 (2012).
The result is called the theoretical yield balance sheet; This corresponds to the U.S. Social Security salary that the worker would have accumulated if he had worked for a 40-year career in the United States with a constant relative pay position of 2.2871073. 5 A QC is a salary, not a period. The amount is adjusted annually. In 2018, profits of $1,320 represent a QC. A worker cannot earn more than 4 QCs in a calendar year, but the worker can reach this threshold by earning USD 5,280 (1,320 × 4) over each period of that year. Tax treaties and totalization agreements were saved in 1935, Congress passed the Social Security Act. The law introduced a taxpayer-funded old-age pension.
 In the 1960s, Congress founded Medicare, which provides seniors with tax-funded health insurance.   To fund Social Security and Medicare, Congress passed the Federal Insurance Contributions Act, also known as the FICA.  As part of the FICA`s December 2017 tax policy, Law 3 imposes different types of payroll tax, workers have withheld their wages: a social security tax of 6.2%, a Medicare tax of 1.45% and, from 2013, a Medicare tax of 0.9% for workers who earn more than $200,000 per year.  In addition, employers must comply with all social security and social security taxes paid by their employees.  This corresponds to a social security tax of about 12% and a Medicare tax of 3% as a percentage of a worker`s base salary.  Although many countries have multilateral totalization agreements (particularly among members of the European Union), US agreements are imposed only as bilateral provisions.
