Have used tax software to do our taxes for many years. Used TurboTax in the past, but switched to H&R block several years ago I believe when they offered some sort of special. I find it helps to stick with the same product each year since various information automatically carries over to the current return. Unless you own a business or have some sort of very unusual income/expense situations, these tax software products are great. No more trying to figure out what goes where, how to input things or do the various calculations. They step you through a series of questions and automatically fill out all of the relevant forms. I also prefer using the software on my home PC compared to inputting something into an online website, just seems more secure to me.
Allows you to file the Federal forms electronically which also works great. The state charges an extra fee to file electronically which makes no sense to me, so I still mail them the completed forms.
