April 15th is always tight for me because I get a few late K-1s every year.
My accountant of many years retired, and I’ve been passed off to someone else at his firm. We’ve made contact, and I was hoping to work with him personally... but that’s not likely, now.
FedEx, email, and phone. The practice is going non-contact, and I don’t blame them a bit.
I usually dont get my k-1 until almost the deadline...but I extend my taxes to October every year. I just overpay my estimates and then roll it to the next year.
