Intuit's Turbo Tax software program long has been the king of do-it-yourself tax preparation, with nearly 30-million customers and a market share of 60-65%.

That's because Intuit quietly made changes in Turbo Tax this year that has its customers screaming bloody murder and its rivals--H&R Block and Tax Act--rubbing their palms together in glee.

H&R Block is even offering irate Turbo Tax customers a free download of its own software program.

Intuit says it's aware of the complaints, it's "sorry for the anger and frustration we have caused many longtime customers," and pledges to resolve the complaints "to their satisfaction" if they'll just call. The uproar over Turbo Tax started almost immediately after New Year's Day, and has been spread by personal finance experts and by word of mouth ever since.

Intuit, however, now has given many of these customers a reason to change.

The task of getting them back once they've become used to, say, H&R Block will be Herculean.

This change enables us to innovate faster and make improvements that benefit all customers at the same time, regardless of whether they use our online or desktop software."When I asked Miller why resolving "customer confusion" required removing functions from Deluxe in a way that confusion, she replied that the goal was to ensure that the desktop version of Deluxe was the same as the online or mobile version.

Of course, Intuit could have added the schedules to the online and mobile versions, instead of removing them from the desktop version--then it would have won plaudits and customer loyalty by .

Nobody buys more than one program per year so they might compare, say, Turbo Tax to H&R Block--who wants to do their taxes twice?

Most people will stick with the same program year after year as long as they're reasonably satisfied with it and don't have a reason to change; since learning the ins and outs of a whole new program is the very definition of a pain in the rear.

Turbo Tax then informs them they have to upgrade to the "Premier" edition, which costs another -, or even to the "Home & Business" version, which is priced above Premier.
