I was wondering how to go about figuring out how much money I should send Uncle Sam. I was W-2 for the first 6 months of the yr and have just started on as k-1. How should I go about in figuring out how much I should pay for the quarter? I was thinking of looking at my last pay stub and just looking to see how much was withheld from my check for the year to date....and then just taking half that amount and sending it to Uncle Sam. Also, how are state taxes figured into all this?
