That would mean that the combined impact of rate increases and scaling back capital cost allowances results in a total loss of $3.2 billion in investment and 93,200 potential or existing jobs.
to account for the impact of investment and tax planning losses that can result from a corporate income tax hike., I estimate that a three-point increase in the corporate income tax rate will cause the corporate tax base to shrink by 15 per cent. This would imply that the NDP estimates of the corporate tax hikes are off by close to $1 billion over three years. This does not include the loss in personal and excise taxes that would result from people becoming unemployed.
