Sec. 1600.22  Maximum contributions.

    (a) Regular employee contributions. A participant's regular TSP 
contributions are subject the following limitations:
    (1) FERS percentage limit. The maximum employee contribution from 
basic pay for a FERS participant for 2005 is 15 percent. After 2005 the 
percentage of basic pay limit will not apply and the maximum 
contribution will be limited only by the provisions of the Internal 
Revenue Code (26 U.S.C.).
    (2) CSRS and uniformed services percentage limit. The maximum 
employee contribution from basic pay for a CSRS or uniformed services 
participant for 2005 is 10 percent. After 2005 the percentage of basic 
pay limit will not apply and the maximum contribution will be limited 
only by the provisions of the Internal Revenue Code.
    (b) Catch-up contributions. (1) A participant may make tax-deferred 
catch-up contributions from basic pay at any time during the calendar 
year if he or she:
    (i) Is at least age 50 by the end of the calendar year;
    (ii) Is making regular TSP contributions at a rate that will result 
in the participant making the maximum regular contributions permitted 
under paragraph (a) of this section; and
    (iii) Does not exceed the annual limit on catch-up contributions 
contained in the Internal Revenue Code.
    (2) Elections to make catch-up contributions will be separate from 
the participant's regular contribution election.
    (3) A participant who has both a civilian and a uniformed services 
account can make catch-up contributions to both accounts, but the total 
amount of the catch-up contributions to both accounts cannot exceed the 
Internal Revenue Code catch-up contribution limit for the year.
    (4) Catch-up contributions are not eligible for matching 
contributions.
