How do I arrange to make TSP retroactive contributions?
This is done directly between you and DFAS-Charleston. If you were on a full-time temporary position and are being converted to a full-time permanent position, DFAS-Charleston will send you a letter with a form to elect a repayment plan. If you were not employed or were part time or intermittent and are being converted to a full time permanent position, the retro payments will automatically be deducted from any back pay due you. All retroactive contributions to TSP must come from future, pretaxed earnings.
