Im still working out a tax snafu with my employer (employer messed up by not entering my W-4 details correctly and significantly under-withheld) and I am going to owe $xx,xxx. I realize I am likely to have to pay it myself, but I haven't resolved the issue and don't want to file a return until I have it all sorted out.
Do I need to go ahead and send a check for the estimated amount due to avoid interest and other penalties on the underpayment from the last year even if I file an extension?
