I've been a fan of Taxcut for several years, and appreciate the ability to use it offline and for multiple returns and multiple states (with purchase after the first free one). It is in general easy to use and simplifies the tax process.
Straightforward and fairly easy to use. Would benefit from better help. If you buy the state add-on, you have to pay a hefty filing fee in addition to initial cost.
Purckase, install, data entry, updates and on line filing were smooth as goat lips. H R Block allowed me to focus on my taxes and not be distracted with technical difficulties.
