With January past and the W-2s out, tax season is upon us. If you’re like me, you can appreciate being able to file online and save yourself some time and, hopefully, some frustration. Don Reisinger, who blogs at The Digital Home, reviews four different online tax preparation software packages in an article for C-NET — H&R Block TaxCut Online, TaxAct Online, TaxSlayer.com and  TurboTax Online.  I’ve used TaxAct for a few years now and have been very satisfied with it, but Reisinger’s article is good because it points out the strengths and weaknesses of each site and who may or may not be in interested in using each one.
