Proposals to Increase the Retirement
Age
The 1983 provision that increased the FRA from 65 to 67 is
fully phased in for those who turn age 62 in 2022 or later.
The increase in the FRA essentially reduces monthly
benefits at all claiming ages, thus reducing the program cost
on average. Research also shows that increasing the FRA
encourages many people to work longer and delay benefit
claiming, thereby increasing payroll tax contributions for
the Social Security program and the average claiming age
for Social Security benefits.
Over the years, many proposals have been put forth to
increase the FRA, increase the EEA, or both. Supporters of
increasing the retirement age contend that the average life
expectancy is increasing, health conditions of older workers
are improving, and job characteristics are more suitable for
older workers. Opponents of increasing the retirement age

often argue that gains in life expectancy and health status,
