Having given this a lot of thought, but still may be wrong about this, I think most of the changes are good.
Income sprinkling, paying dividends to family that didn't buy equity is wrong and should rightfully be stopped. However, salaries paid to family is likely more legit and the tax savings is very small as only the first $30k paid to a family member in income is tax efficient, so making a huge burden for corps to prove income is 'fair' may be overdoing it.
Lifetime capital gains and converting dividends to capital gains are also loopholes that shouldn't exist, so I am happy to see these closed.
Finally, taxing passive income is where I have issues and think these measures are overreaching. Small businesses have higher risk and no pensions, they should not be treated like employees at bigger corps. Also, large corporations get the benefit of lower taxes on retained earnings, why is it fair that small corp can't get the same benefit? I am very against these proposed changes.
One other thing, rich people I know use the above measures but mostly through family trusts. By not extending these rules to family trusts, then I don't think you are really achieving much. You are penalizing small businesses, likely causing too much paperworks, and you aren't getting at the real schemes that actually do dodge taxes.
I would love to hear if I have any of this wrong, so please let me know. I want to be sure I completely understand this.
