Short-term tax cut for service members must be repaid in early 2021

"Tens of thousands of people will receive bigger paychecks for the last few months of the year, as the U.S. marches toward the November election.

Then, the government will begin to collect the tax again and simultaneously collect all the deferred tax by withholding it from paychecks from Jan. 1 to April 30, 2021, meaning these same individuals will receive smaller paychecks than before the tax deferral."
