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 are obsolete and most forms are originated online within TSP.

Starting in 2026 you will be able to convert traditional TSP to Roth TSP in the plan, but you will need to pay the income tax for the conversion from other sources, not from the TSP.
