Actively employed Thrift Savings Plan investors who are 50 or older this year still may make “catch-up” contributions for the calendar year, although time is growing short for them to do so. Catch-up contributions, which can be up to $2,000 this year, are over and above the dollar amount or percentage of salary investment limits, but like regular investments must be made from payroll withholding. Taking into account processing time, there would be only a few pay periods remaining in the year for employees to make those contributions. The entire amount of a catch-up contribution can be taken from only a few-or even just one-pay, assuming the employee’s pay is high enough and the individual can get by with such a large reduction. Catch-ups are made by filing form TSP-1-C.
