Well, sure, Monday is Columbus Day and a federal holiday. That doesn’t bother me. However, the problem is that with just nine days left before the extension deadline, the IRS shuts off all of its computer systems for a scheduled power shut-off in Martinsburg, West Virginia. I could ask why this isn’t scheduled for, say, Thanksgiving weekend or the end of October. No matter, if you are an authorized IRS e-services provider (like I am), you can’t do anything until Tuesday.
