Over the years, Canada has bolstered its tax code, writes Heather Scoffield, but the wealthy are often a step ahead, especially those who can navigate increasingly murky financial transactions.

Canadian parliamentarians are taking a crack at squeezing out more government revenue from tax havens, and we wish them all the luck and stamina.

Tucked away from the Conservative-to-Liberal floor-crossings and the nail-biting confidence-vote drama that have dominated this Parliament, MPs on the House of Commons finance committee were contemplating all the places where corporations put their profits.

What initially started as an Opposition “gotcha” strategy meant to tie Prime Minister Mark Carney to the tax practices of Brookfield Asset Management has turned into a fairly serious exercise to tackle one of the thorniest issues in fiscal policy.

Political soap opera this ain’t, but the implications are in the billions of dollars every single year — and Canada is missing out.

That’s anything but new, and Canada is far from alone. Tax avoidance and its more nefarious cousin, tax evasion, have bedevilled policymakers for time immemorial.

Over the years, Canada has thickened its tax code, added auditing resources and investigative powers to the Canada Revenue Agency and law enforcement, joined complex international agreements and is always adopting more advanced technology in the hopes of gaining the upper hand.

But companies and wealthy individuals often seem to be a step ahead, especially those that are well-resourced enough to navigate increasingly complex rules and murky financial transactions.

It’s worth taking another run at it.

Taxing corporations and high net-worth families fairly is more important than ever. Canada needs the economic activity, governments need the tax revenue, and Canadians need to know that the tax system that they pay into — year in, year out — is equitable.

“There’s a constant balancing act between competitiveness — we want our businesses and our multinationals to succeed when they’re competing in foreign markets — and a desire to not facilitate inappropriate tax avoidance and erode the Canadian tax base,” Trevor McGowan, associate assistant deputy minister at the Department of Finance, told the committee.

Canada, like many other countries, is thirstier than ever for business investment, especially now that the global economy is in an uproar and the United States is no longer a dependable source of mutual benefit. And with trust in public institutions in a fragile state, the federal government can’t afford to be lenient.

Parliamentarians find it hard to determine the scope of the problem. CRA has measured the “tax gap” — the difference between what corporations should be paying and what they actually pay — in the past and says that in 2018 it amounted to between $1 billion and $3 billion a year, lower than previous years.

But CRA’s efforts focus on tax evasion (actually breaking the law) rather than tax avoidance, which is just playing footsie with the rules. And they admit up front that their estimate is uncertain.

Independent analysts who try anyway to measure the cost of tax avoidance come up with far higher numbers. Canadians for Tax Fairness figures Canada misses out on $15 billion a year because of tax haven abuse.

But as the prime minister himself said when he was faced with tough questions about Brookfield during the election campaign last spring, setting up corporate shop in a low-tax jurisdiction is legal and a legitimate business strategy.

Even trickier than counting up the missing tax revenue is figuring out what to do about it.

Canada has tax treaties and agreements with a growing number of key low-tax or no-tax jurisdictions — agreements backed up by domestic law that actually allows for Canadian firms to repatriate some types of income back to Canada without paying tax.

In the past few years, the federal government has tightened the screws.

• Like many other developed countries, Canada now imposes a global minimum tax of 15 per cent, mainly touching large companies with foreign subsidiaries. The Department of Finance sees collecting an extra $2.1 billion a year this way.
• Ottawa has now curtailed the deduction of excessive interest and expenses, expecting to raise between $1.6 billion and $1.8 billion a year.
• The government has significantly boosted CRA’s budget for audits and has also updated its anti-avoidance rules that apply to corporations.
• In the last budget, the federal government bolstered its authority over transfer pricing that companies use to account for in-house international trade.

Officials believe their measures are chipping away successfully at the tax avoidance problem, delivering results.

Critics and parliamentarians of all stripes want more though — with good reason. But there are no magic solutions.

The approach of the past has often been to add more rules and complexities, but there’s a chance that amounts to a road map for dodgy activity. The same issues apply to multilateral agreements and tax treaties.

If the entities you’re trying to stymie specialize in hiding behind complexity, adding even more complexity may make things worse. Simpler rules, on the other hand, could help.

The other main approach is transparency. Europe and Australia are legislating public country-by-country reporting (PCBCR), which requires multinational corporations to make public key financial data in every country they operate.

Canada has some requirements along these lines but the information is not public.

The hope is that transparency will dampen tax avoidance.

“PCBCR really is sunlight as the best disinfectant. It would allow academics and researchers outside of the tax authorities to engage in the kind of research that we need to deal with this whack-a-mole problem,” D.T. Cochrane, senior economist at the Canadian Labour Congress, told the committee.

“There will always be incentive to create these schemes. We need more methods of confronting them.”

A balancing act indeed.
