The IRS-imposed dollar limit on allowable individual contributions the TSP
will stay in 2008 at the $15,500 limit applying in 2007. Those under the FERS
system should make sure to structure their investments so that they can keep contributing throughout the calendar year; when they hit the limit, government matching contributions on their behalf will cut off. That isn't a concern for CSRS investors, who get no employer contributions. Also, investors age 50 and older during 2008 can make special "catch-up" investments over and above the dollar limit of $5,000, again the same limit that applied in 2007.
