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.
I used do that every year. But the guy I worked with usually wanted to git ‘er done and relax after the deadline, so I was fine working with him on his schedule. When he hit 70, he decided he didn’t want to live like that in tax season, and didn’t have to.
A long, happy professional relationship.
Last summer I was driving and he called me. I asked if he was calling because I was being audited or because he was retiring.
