Federal finance minister, Bill Morneau recently released a long and nervously awaited discussion paper which was met with near apoplexy in some corners. The paper aimed at closing a number of loopholes where mainly rich taxpayers use private companies (Canadian controlled private corporations or CCPCs) to reduce their taxes compared to most Canadians whose incomes come through pay cheques or self-employment.

The proposals would fulfil a Liberal campaign promise to address unfair uses of some arcane provisions of Canada’s income tax act.  In response, one tax practitioner said in a popular newsletter, “Finance Minister Bill Morneau just announced the Trudeau government’s plan to destroy tax planning as we know it.”  The Minister has given the public 75 days to respond.

So far, most of the comments have been rather general.  One is that these provisions will hurt the middle class much more than the rich.  This is clearly false, as shown in a study I published with my colleagues last year.  For the bottom 50 per cent of income tax filers in 2011, those with incomes under $51,600, well under 10 per cent had a non-trivial interest in a private company.  But for the top 1 per cent with incomes over $163,300, more than 50 per cent had a significant interest in a private company — and for the top 0.01 per cent with incomes over $2.3 million, this figure jumps to almost 80 per cent.

Further, as I showed in a study published just before the 2015 election and cited in debates at the time between (then) candidate Justin Trudeau and Prime Minister Stephen Harper, federal and provincial governments were foregoing at least half a billion dollars each and every year in income tax revenues from the use of these private companies for income splitting.

Among those likely to be affected by the Minister’s proposals are higher income doctors, some of whom have even threatened to flee the country if these loopholes are tightened.

Before the Ontario budget in 2005, doctors’ spouses could not be shareholders in a private company set up to receive the doctor’s income.  But as part of the fee negotiations at that time, the government of Ontario made a very obscure change to their corporate law allowing these spouses to become shareholders.  This change was clearly a backdoor way to increase the incomes of doctors and their families without most of the public noticing.  Even though the public remained unaware, the number of private doctor companies in Ontario, which had been rising slowly up to 2004 at under 1,500, climbed steeply after this budget in 2005 to over 16,000 in 2011 — more than a ten-fold increase — and, according to the OMA, to over 20,000 today.

Obviously, this obscure legal change must have provided substantial benefits for so many doctors to incur the costs of setting up their own private companies.  And if the Province of Ontario wants to help doctors maintain their after-tax incomes, they could always support the federal government in closing these loopholes and then use their own resulting increased tax revenues to increase their payments explicitly, through the front door, rather than hiding these very real benefits via obscure back door tax breaks.

More broadly, many in the business community and some leading economists tout the major benefits of cutting corporate income taxes to improve economic growth.

But there’s a very revealing graph in the Minister’s discussion paper.  It shows that the taxable incomes of mainly larger public companies, even with all the major corporate income tax cuts since 2000, were quite stable as a percentage of GDP from 2002 to 2014.  Over this same period, the percentage shares of GDP for the incomes of the self-employed fell by about one quarter.  In contrast, the most dramatic growth was for small private corporations, the ones able to exploit the income splitting loopholes, whose incomes more than doubled as a share of GDP.

Was the decline in incomes of the self-employed, while the incomes in private companies nearly doubled, nothing more than an increasing number of well-advised higher income individuals learning to exploit tax loopholes?  We cannot tell with the available data.  But we could know if the government followed the Auditor General’s Spring 2015 recommendations to be much more open and fulsome in their public reporting on these kinds of tax provisions.

So no, the sky is not falling on Canada’s small businesses.  The Minister’s proposals would clearly increase tax fairness.  Indeed, the extra revenues collected from mainly higher income individuals, by bringing their effective income tax rates more in line with their salaried counterparts, could be used to benefit the poor and those in the middle class.
