The TSP Modernization Act was finally implemented on September 15th, 2019. Now employees over 59.5 years of age and retirees can have more than one partial withdrawal in a lifetime, can opt for monthly, quarterly and or annual payments, can change payment amount for monthly payments more frequemtly than once a year, and can specify the percentage of Roth or traditional TSP that comes out in a withdrawal or series of payments.

All withdrawal forms dated before September 2019 are obsolete and most forms are originated online within TSP.
