Disapproval for the federal government's proposed tax changes crosses party lines in Saskatchewan legislature.

The governing Saskatchewan Party has been very vocal against the proposal and Saskatchewan NDP Finance Critic Cathy Sproule isn't a fan either.

"Based on conversations I've had with mostly farmers here in Saskatchewan, but also some of our constituents who are doctors, is what appears to me is a complete lack of thinking through the impact of the changes," the Saskatoon Nutana MLA said. "I don't think the consultation period was adequate at all - starting in the summer and then winding it up now. It takes a while for the accounting community, the legal community, and the taxpayers themselves to sort of work through all these changes."

Sproule said it's a horrible approach that would hurt small businesses and farmers and it could undo decades of "careful tax planning."

There are three so-called loopholes targeted by the proposal: income sprinkling, passive investments, and capital gains. Of the three, Sproule said she doesn't mind the government targetting passive income.

"It depends on what the passive money is being used for - the intentions - but I think passive income is kind of an easy target and maybe it should be targeted a little bit - stocks and bonds - because it means it's income that you're not putting in your blood, sweat, and tears to make a business," she said. "Businesses, and especially a start up, and you think of medical practitioners starting their university and the investment it takes to get to that point, plus creating jobs and all that, that's important income. The passive income maybe is one area where there could be tax reform."

Overall Sproule thinks the government ought to work with the international community at targeting offshore tax havens, though it can be hard to orchestrate things on the international level.

"Obviously tax fairness is an important concept, and I think it has to be done fairly. I'm not sure that it is right now - and maybe there are some changes that need to be implemented - but I think tax havens is the number-one most-egregious, outrageous space that I think the entire international community and governments have allowed to happen. That is where the real problem is - it's where money isn't being taxed at all. I'd like to see more resources put into that."

The federal Liberal government hasn't responded to interview requests, though Canada Finance Minister Bill Morneau did say recently that they are open to change. The consultation period ends October 2.
