Table shows the contribution (tax) rates used to determine total amounts received by the trust funds. Occasional temporary tax credits and rate reductions affect the rates paid by employers, employees, or self-employed persons, and are summarized in footnotes as applicable.
a. Based on automatic adjustment, under legislation in 1972 (as modified by legislation in 1973), in proportion to increases in average wage level.
b. In 1984, the 5.7 percent OASDI tax on taxable wages of employees was offset by a tax credit of 0.3 percent, resulting in an effective employee tax rate of 5.4 percent. However, the OASDI trust funds received the full 5.7 percent because of a general revenue transfer equivalent to 0.3 percent of taxable wages. Similar credits of 2.7 percent, 2.3 percent, and 2.0 percent were allowed against the combined OASDI and HI taxes on net earnings from self-employment in 1984, 1985, and from 1986 to 1989, respectively.
c. Based on automatic adjustment, under legislation in 1972 (as modified by legislation in 1973), using a transitional rule, specified by the Omnibus Budget Reconciliation Act (OBRA) of 1989, for computing a "deemed" average annual wage for 1988, 1989, and 1990.
d. Based on legislation in 1990.
e. Upper limit on earnings subject to HI taxes was repealed by OBRA 1993.
f. For 2010, most employers were exempt from paying the employer share of OASDI tax on wages paid to certain qualified individuals hired after February 3. Amounts equal to the revenue forgone were transferred from the general fund of the Treasury to the OASI and DI Trust Funds.
g. For 2011 and 2012, the combined OASDI payroll tax rate was reduced by 2.0 percent for employees and for self-employed workers, resulting in a 4.2 percent effective tax rate for employees and a 10.4 percent effective tax rate for self-employed workers. The authorizing legislation does not specify percentage reductions attributable to the separate OASI and DI Trust Funds. Amounts equal to the revenue forgone were transferred from the general fund of the Treasury to the trust funds.
h. Beginning in 2013, an additional HI tax of 0.9 percent is assessed on earned income exceeding $200,000 for individuals and $250,000 for married couples filing jointly. This additional HI tax rate is not reflected in the contribution rates shown in the table.
i. Public Law 114-74, the Bipartisan Budget Act of 2015, temporarily re-allocated a portion of the OASI tax rate to DI for calendar years 2016 through 2018.

Table shows the maximum contributions (taxes) received by the trust funds from an individual worker. Occasional temporary tax credits and rate reductions affect the amounts paid by workers, and are summarized in footnotes as applicable.
a. In 1984, the 5.7 percent OASDI tax on taxable wages of employees was offset by a tax credit of 0.3 percent, resulting in an effective employee tax rate of 5.4 percent. However, the OASDI trust funds received the full 5.7 percent because of a general revenue transfer equivalent to 0.3 percent of taxable wages. Similar credits of 2.7 percent, 2.3 percent, and 2.0 percent were allowed against the combined OASDI and HI taxes on net earnings from self-employment in 1984, 1985, and from 1986 to 1989, respectively.
b. Upper limit on earnings subject to HI taxes was repealed by the Omnibus Budget Reconciliation Act (OBRA) of 1993.
c. For 2011 and 2012, the combined OASDI payroll tax rate was reduced by 2.0 percent for employees and for self-employed workers. Thus, for 2011, the maximum OASDI contribution for employees was $4,485.60 and for self-employed workers was $11,107.20; and for 2012, the maximum OASDI contribution for employees was $4,624.20 and for self-employed workers was $11,450.40. The authorizing legislation does not specify percentage reductions attributable to the separate OASI and DI Trust Funds. Amounts equal to the revenue forgone were transferred from the general fund of the Treasury to the trust funds.
d. Beginning in 2013, an additional HI tax of 0.9 percent is assessed on earned income exceeding $200,000 for individuals and $250,000 for married couples filing jointly. This additional HI tax amount is not reflected in the contribution amounts shown in the table.
e. Public Law 114-74, the Bipartisan Budget Act of 2015, temporarily re-allocated a portion of the OASI tax rate to DI for calendar years 2016 through 2018.

Tables 2.A3 and 2.A4 show the tax rate and tax amount paid by employers and received by the OASDI trust funds.
