when does irs mail checks
What day of the week does the IRS mail out refund checks? Best Answer: False. The IRS has two computer systems. System #1 mails checks only on Fridays. It handles most tax returns and all amended returns. System #2 (CADE) can generate checks any day of the week. The checks are dated 2-3 days after they are mailed. That is the checks mailed today, July 31st, are dated Monday, August 3rd.
