underpayment rates drop dramatically

Federal underpayment rates will drop for Q4 of 2011 to 3%.  Not bad.  If you can manage not to incur the failure-to-file or failure-to-pay penalties, say in an amended return situation, your loan from the United States is now really quite reasonable, considering that rates for a typical mortgage rate are still over 4%.  The duty to file an amended return … is an interesting legal area.
