This seems like a startup opportunity. Take photos of your standardized forms, upload them to a server, server calculates your taxes, only asking questions when the pertinent data is missing from the forms.
IMHO this service should be offered by the government(s) themselves (and if it was, it would mean even less data needed to be entered; after all, they have copies of all your forms already), but fat chance on that.
This is exactly what HRBlock and Intuit currently do. They have hooks into all the payroll processors and investment companies and will download your W2s and any 1099s from the relevant company. Then you just answer a bunch of questions.
The problem is that a private company shouldn't have to offer this service. The government should do it for you for free because it helps them get their money faster and easier. However, as the article and others noted, those private companies realize this would be very bad for their business and have lobbied to stop it.
Intuit TurboTax (http://www.turbotax.com) has been doing this for years, but charges ~$50 for federal and ~$30 for state (and a little more if you have a business.)
