this was my first year to report and be taxed on IRA distributions, and some of the reporting and the variety of documents from financial institutions were confusing. Also, I owed taxes, and was surprised after selecting the pay by credit card option, having irrevocably submitted my Fed return, that I owed an additional 'convenience fee'. this should have been noted at the selection process, not after I could not recall my return and make another choice.
Tennessee has changed their payment web site and will not take payments on it until May 29th according to the page the SOFTWARE LINKED TO! But, you've already dinged my credit card for an epay charge!
