There is no exact information to be had :
Here is the plan Treasury Secretary Mnuchin announced last week … anticipated dates:
Direct Deposit - figure between April 9 - 14; if you did not file but receive Social Security, figure direct deposit by the end of April
Checks - they will begin the week of April 24 processing in 'income order'. So those with incomes under $10,000 will be processed the week of April 24, those with incomes under $20,000 the week of May 1, etc.
