The most recent pay adjustment for Members of Congress was in January 2009. Selected CRS Products

This report provides historical tables on the rate of pay for Members of Congress since 1789; details on enacted legislation with language prohibiting the automatic annual pay adjustment since the most recent adjustment; the adjustments projected by the Ethics Reform Act as compared with actual adjustments in Member pay; and Member pay in constant and current dollars since 1992. It has been used periodically since, most recently affecting pay for 1991. Prior to 1990, the pay of Members, and other top-level federal officials, was tied to the annual comparability increases provided to General Schedule (GS) federal employees. This procedure was established in 1975 ( P.L. January 2020 Potential Pay Adjustment

The maximum potential January 2020 Member pay adjustment of 2.6%, or $4,500, was known when the Bureau of Labor Statistics (BLS) released data for the change in the Employment Cost Index (ECI) during the 12-month period from December 2017 to December 2018 on January 31, 2019. The 2019 GS base pay adjustment was 1.4%, automatically limiting any Member pay adjustment to $2,400. 115-244 , enacted September 21, 2018, included the pay freeze provision. The 2018 GS base pay adjustment was 1.4%, automatically limiting any Member pay adjustment to $2,400. 115-56 , through December 8, 2017; P.L. P.L. 115-56 contained a provision, extended in the subsequent CRs, continuing "section 175 of P.L. 114-254 ." 114-113 ). Absent the statutory prohibition on a Member pay adjustment, Members of Congress would have automatically been limited to a 1.0% ($1,700) salary increase to match the increase in base salaries for GS employees. The scheduled January 2014 across-the-board increase in the base pay of GS employees under the annual adjustment formula was 1.3%. Had the Member pay adjustment not been prohibited by law, the GS base pay adjustment would have automatically limited a salary adjustment for Members of Congress to 1.0% ($1,700). The adjustment takes effect automatically unless (1) denied statutorily by Congress or (2) limited by the GS base pay adjustment, since the percentage increase in Member pay is limited by law to the GS base pay percentage increase. 111-322 through the duration of this continuing resolution. 112-175 . 112-240 ), froze Member pay at the 2009 level for 2013. Pay adjustments in both years were further frozen pursuant to subsequent laws. 5146 ( P.L. 111-165 ) on May 14, 2010. Other legislation was also introduced to prevent the scheduled 2011 pay adjustment. Additionally, P.L. 111-322 , which was enacted on December 22, 2010, prevents any adjustment in GS base pay before December 31, 2012. Since the percentage adjustment in Member pay may not exceed the percentage adjustment in the base pay of GS employees, Member pay is also frozen during this period. If not limited by GS pay, Members could have received a salary adjustment of 1.3% in January 2012 under the ECI formula. Pay for Members of Congress remained $174,000. January 2010 Member Pay Adjustment Denied

Under the formula established in the Ethics Reform Act, Members were originally scheduled to receive a pay adjustment in January 2010 of 2.1%. Had this provision not been enacted, the 2.1% projected adjustment would have been automatically reduced to 1.5% to match the 2010 GS base pay adjustment. 113-3 ). The differences between the projected and actual Member pay adjustments resulted from
the enactment of legislation preventing the increase (adjustments for 1994, 1995, 1996, 1997, 1999, 2007, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, and 2019); limits on the percentage increase of Member pay because of the percentage increase in GS base pay (adjustments for 1994, 1995, 1996, 1998, 1999, 2001, 2003, 2007, 2008, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, and 2019); and a combination of the above. If Members of Congress had received every adjustment prescribed by the ECI formula since 1992, and the 2 U.S.C. §4501 limitation regarding the percentage base pay increase for GS employees remained unchanged, the 2019 salary would be $210,900. While many of the bills in this list are appropriations bills, a prohibition on Member pay adjustments could be included in any bill, or be introduced as a separate bill. It shows that Member salaries, when adjusted for inflation, decreased 15% from 2009 until 2019.
Congress is required by Article I, Section 6, of the Constitution to determine its own pay. In the past, Congress periodically enacted specific legislation to alter its pay; the last time this occurred affected pay in 1991. More recently, pay has been determined pursuant to laws establishing formulas for automatic adjustments.
The Ethics Reform Act of 1989 established the current automatic annual adjustment formula, which is based on changes in private sector wages as measured by the Employment Cost Index (ECI). The adjustment is automatic unless denied statutorily, although the percentage may not exceed the percentage base pay increase for General Schedule (GS) employees. Member pay has since been frozen in two ways: (1) directly, through legislation that freezes salaries for Members but not for other federal employees, and (2) indirectly, through broader pay freeze legislation that covers Members and other specified categories of federal employees.
Members of Congress last received a pay adjustment in January 2009. At that time, their salary was increased 2.8%, to $174,000. A provision in P.L. 111-8 prohibited any pay adjustment for 2010. Under the pay adjustment formula, Members were originally scheduled to receive an adjustment in January 2010 of 2.1%, although this would have been revised downward automatically to 1.5% to match the GS base pay adjustment. Members next were scheduled to receive a 0.9% pay adjustment in 2011. The pay adjustment was prohibited by P.L. 111-165. Additionally, P.L. 111-322 prevented any adjustment in GS base pay before December 31, 2012. Since the percentage adjustment in Member pay may not exceed the percentage adjustment in the base pay of GS employees, Member pay was also frozen during this period. If not limited by GS pay, Member pay could have been adjusted by 1.3% in 2012. The ECI formula established a maximum potential pay adjustment in January 2013 of 1.1%. P.L. 112-175 extended the freeze on GS pay rates for the duration of this continuing resolution, which also extended the Member freeze since the percentage adjustment in Member pay may not exceed the percentage adjustment in GS base pay. Subsequently, Member pay for 2013 was further frozen in P.L. 112-240. The maximum potential 2014 pay adjustment of 1.2%, or $2,100, was denied by P.L. 113-46. The maximum potential January 2015 Member pay adjustment was 1.6%, or $2,800. President Obama proposed a 1.0% increase in the base pay of GS employees, which would automatically have limited any Member pay adjustment to 1.0%. P.L. 113-235 contained a provision prohibiting any Member pay adjustment. The maximum potential January 2016 pay adjustment of 1.7%, or $3,000, would have been limited to 1.0%, or $1,700, due to the GS base pay increase. Member pay for 2016 was frozen by P.L. 114-113. The maximum potential January 2017 pay adjustment of 1.6%, or $2,800, would have been limited to 1.0%, or $1,700, due to the GS base pay increase. Member pay for 2017 was frozen by P.L. 114-254. The maximum potential January 2018 pay adjustment of 1.8%, or $3,100, was automatically limited to 1.4%, or $2,400, before being frozen by P.L. 115-141. The maximum potential January 2019 pay adjustment of 2.3%, or $4,000, was automatically limited to 1.4%, or $2,400, before being frozen at the 2009 level by P.L. 115-244. The maximum potential January 2020 pay adjustment is 2.6%, or $4,500.
If Members of Congress had received every adjustment prescribed by the ECI formula since 1992, and the 2 U.S.C. §4501 limitation regarding the percentage base pay increase for GS employees remained unchanged, the 2019 salary would be $210,900. When adjusted for inflation, Member salaries have decreased 15% since the last pay adjustment in 2009.
Both the automatic annual adjustments and funding for Members' salaries are provided pursuant to other laws (2 U.S.C. §4501)—not the annual appropriations bills—and a provision prohibiting a scheduled adjustment could be included in any bill, or introduced as a separate bill.
