The plan was announced by Barry Pennett, Intuit ProConnect general manager this week. But it added little to what the company said last month and named no additional integrations. The company has said it will integrate Karbon with ProSeries and Lacerte and possible with other practice management products

"We believe that meaningful relationships are at the heart of every interaction between clients and tax professionals, and reducing the compliance work will free up time so that professionals can focus more of their time giving valuable advice to their clients, helping them reach their goals," Pennett said in a prepared statement.

The usual step for opening up a product to development is to make a software developments kit available to third parties. An SDK has been available for years for QuickBooks, but Intuit has not announced one for the tax packages.
