The Republican-controlled Senate Budget Committee is expected to reject President Reagan's proposals to raise the earliest federal retirement age from 55 to 62, increase employe pension contributions from 7 percent to 9 percent and deny federal retirees a cost-of-living adjustment next January.

Administration attempts to raise the minimum retirement age have frightened and angered federal employes, who consider the mid-career rules change a breach of contract. Under current law, civil servants may retire at age 55 after 30 years and receive pensions equal to 56 1/4 percent of the average salary over their three highest-paid years. To get the maximum benefit -- 80 percent of salary -- they must work about 42 years.

Although the average government worker retires at age 61, most employes want to keep the option of quitting earlier.

The administration originally proposed raising the retirement age to 65, the age at which people may collect full Social Security benefits. But this year the White House asked that it be made 62, the age when people can begin drawing reduced Social Security benefits.

Under the president's plan, which will probably die if the Budget Committee rejects it, employes could still retire "early," but with a penalty of 2 percent of the pension for each year they are under age 62.

The committee is still working on tax and defense items, but insiders say that most of the major civil service issues have tentatively been approved.

Committee sources believe that many of the savings that will be assigned to the civil service can be made in the new supplemental retirement system. Congress is due to establish the system in May for workers hired since 1984.

Earlier this month the House Post Office-Civil Service Committee voted overwhelmingly to reject all of the president's civil service budget requests. Meetings
