Thanks. A followup question on the rules posted. it says that I may still owe a penalty if estimated payment for one period is less than 25% of the amended estimated tax. I am not even sure what that means. If my K1 is coming next year, how can I count that in my estimation? And if I make huge money in December (say huge bonus) then the best I can do is to up my Estimated Taxes in Jan. But looks like that can also cause penalty for me?
