The Global Minimum Tax and Your XEQT Portfolio: What It Means for the Companies You Own

A friend of mine texted me out of nowhere last week. No greeting, no small talk – just a screenshot of a Financial Post headline about the global minimum tax and a single line: “Does this affect my XEQT?”

I stared at the message for a second and laughed, because I had been down the exact same rabbit hole a few months earlier. I’d seen the phrase “global minimum tax” pop up in a Budget 2024 summary, then again in an OECD press release, and then a third time in a Reddit thread where someone was panicking about their portfolio. Three different sources, three different levels of alarm, and none of them told me what I actually wanted to know: as someone who just buys XEQT every month, should I care?

So I did what I always do. I dug into the details, read more policy documents than any normal person should, and came away with a clear answer. The short version: yes, the global minimum tax is a real structural change to how multinational corporations are taxed around the world. And yes, it affects some of the biggest companies inside your XEQT portfolio. But no, it is not a reason to change your strategy. Not even close.

Let me walk you through all of it.

1. What Is the Global Minimum Tax? (In Plain English)

Let’s start with the basics, because the phrase “OECD Pillar Two Global Anti-Base Erosion Rules” is not exactly designed for casual conversation.

Here is the simple version: over 140 countries have agreed that large multinational companies should pay a minimum corporate tax rate of 15%, no matter where they book their profits. That is the global minimum tax. It is part of a broader international agreement coordinated by the OECD (the Organisation for Economic Co-operation and Development), and it specifically targets companies with annual revenues above 750 million euros – roughly $1.1 billion CAD.

To understand why this matters, you need to understand what was happening before.

For decades, large multinational corporations have used sophisticated tax planning to shift their profits to low-tax jurisdictions. You have probably heard the stories. A tech company earns billions in revenue from customers around the world, but its intellectual property is held by a subsidiary in Ireland, where the corporate tax rate was as low as 12.5%. The profits get funneled through the Irish entity, and the company pays far less tax than it would in the US or Canada.

This was not illegal. It was just how the system worked. Countries like Ireland, Luxembourg, Singapore, the Netherlands, Bermuda, and the Cayman Islands attracted corporate headquarters and subsidiaries by offering low or zero tax rates. The result was a global “race to the bottom” where countries competed to offer the most favorable tax treatment.

Pillar Two changes that. Under the new rules, if a multinational company’s effective tax rate in any country falls below 15%, the company’s home country can impose a “top-up tax” to bring the rate up to the minimum. So even if Apple routes profits through Ireland, the US (Apple’s home country) can collect the difference between Ireland’s actual rate and the 15% floor.

The key concepts to know:

• IIR (Income Inclusion Rule): The home country of the parent company charges a top-up tax on undertaxed foreign profits
• UTPR (Undertaxed Profits Rule): If the home country does not apply the IIR, other countries can deny deductions or impose additional taxes
• QDMTT (Qualified Domestic Minimum Top-up Tax): A country can choose to impose the top-up tax itself, keeping the revenue domestically rather than letting another country collect it

If those acronyms made your eyes glaze over, don’t worry. The bottom line is straightforward: the days of massive multinational companies paying single-digit tax rates by shifting profits to tax havens are coming to an end. The 15% floor does not eliminate tax planning entirely, but it puts a meaningful limit on how low effective tax rates can go.

2. Which Companies Inside XEQT Are Affected?

Now let’s connect this to what you actually own.

If you hold XEQT, you own more than 9,000 individual stocks across 49 countries. Some of the biggest names in your portfolio are precisely the companies that benefited most from aggressive international tax planning – and they are the ones most affected by Pillar Two.

Here is a look at some of the most impacted sectors and companies inside XEQT:

The pattern is clear: the companies most affected are large, US- and Europe-headquartered tech and pharma multinationals that have historically used intellectual property structures to minimize taxes. These are real, well-known companies that make up a significant chunk of XEQT’s holdings.

But here is the critical nuance. Even for the most affected companies, we are not talking about a dramatic overnight hit to earnings. We are talking about gradual, incremental increases in effective tax rates – in most cases, from somewhere in the low-to-mid teens to at least 15%. Some of these companies were already paying rates close to or above the minimum in many jurisdictions.

3. How This Changes Corporate Earnings (and How Much)

Alright, let’s talk numbers. Because the question everyone really wants answered is: how much does this actually cost the companies I own?

The honest answer is: less than you might think.

Multiple analyses from major investment banks and tax advisory firms have estimated the aggregate impact of Pillar Two on global corporate earnings. Here is a summary of what the research says:

• For the most affected companies (those with effective tax rates well below 15% in key jurisdictions), earnings per share could decline by roughly 2-5% as top-up taxes take effect.
• For the average large multinational, the impact is closer to 1-2%.
• For XEQT as a whole, the impact is significantly diluted because the portfolio holds thousands of companies, the vast majority of which were already paying effective rates at or above 15%.

To put this in perspective, let’s say the global minimum tax reduces aggregate XEQT earnings by 1%. If XEQT was expected to return 8% in a given year based on historical averages, the global minimum tax might shave that down to roughly 7.9%. Over a 25-year investing horizon, that difference is almost impossible to distinguish from normal market noise.

Here is another way to think about it. XEQT’s underlying companies collectively earn hundreds of billions of dollars annually. The global minimum tax is estimated to raise approximately $220 billion USD globally per year once fully implemented. That sounds enormous – and it is, from a government revenue perspective. But spread across the thousands of multinational companies affected, and then diluted further by the fact that XEQT holds thousands more companies that are barely affected at all, the per-share impact on your portfolio is remarkably small.

And here is the part that matters most: markets are forward-looking. Pillar Two has been discussed publicly since 2021. The OECD framework was agreed to in late 2021 and early 2022. Countries began enacting legislation in 2023 and 2024. By now, in mid-2026, the market has had years to price in the impact of the global minimum tax. If you are buying XEQT today, you are buying at a price that already reflects this reality. The tax change is not a surprise that will suddenly crater your portfolio – it is old news that has already been digested by the market.

4. What This Means for Your XEQT Returns

Let’s zoom out even further. I think one of the most valuable things about holding a broadly diversified fund like XEQT is that it forces you to think about your portfolio the right way – as a massive, self-correcting system rather than a collection of individual bets.

When the global minimum tax increases the tax burden on, say, Apple’s Irish subsidiary, a few things happen:

1. Apple’s after-tax earnings decrease slightly. This is the direct, first-order effect.
2. Apple adjusts. The company may restructure operations, adjust pricing, or find other (legal) ways to optimize its tax situation within the new framework. Companies are incredibly adaptive.
3. Governments collect more revenue. That revenue gets spent on infrastructure, services, and programs that can stimulate economic activity – some of which benefits the very companies in your portfolio.
4. The competitive landscape shifts. Companies that were paying their fair share all along are now on a more level playing field with companies that were aggressively minimizing taxes. This can actually improve market efficiency.

When you own 9,000+ stocks, these effects compound and offset each other in ways that make the net impact on your portfolio minimal. Some companies pay a bit more in tax. Some benefit from the fairer competitive environment. Government spending funded by the new revenue flows back into the economy. The system adjusts.

This is exactly what diversification does for you. It does not eliminate every risk – nothing can do that. But it ensures that no single policy change, in any single country, aimed at any single type of company, can materially derail your long-term investment plan.

And here is some historical context that should make you feel better. Corporate tax changes are not new. The world has been raising and lowering corporate tax rates for over a century, and markets have adapted every single time:

• The US Tax Cuts and Jobs Act of 2017 slashed the US corporate rate from 35% to 21%. Markets cheered. Earnings jumped. But long-term returns were driven far more by economic fundamentals than by the one-time tax change.
• Canada raised its GST, then lowered it, then changed corporate tax rates multiple times. Each change generated headlines. None of them were a reason to sell your portfolio.
• The European Union has been tightening tax rules on multinationals for years, including landmark cases against Apple and Amazon. Markets absorbed each change and moved on.

The pattern is always the same: short-term noise, long-term irrelevance for diversified investors.

5. Why Canada Specifically Matters Here

If you are a Canadian investor – and if you are reading this site, you probably are – there is a specific Canadian angle to this story that is worth understanding.

Canada was one of the early adopters of Pillar Two. The federal government passed the Global Minimum Tax Act as part of its 2024 budget implementation, making Canada one of the first countries to formally enact the OECD’s model rules into domestic law. The legislation took effect for fiscal years beginning on or after December 31, 2023.

What this means practically:

• Canadian-headquartered multinationals with revenues above the 750 million euro threshold are now subject to the top-up tax rules. If their foreign subsidiaries pay effective tax rates below 15% in any jurisdiction, Canada can collect the difference.
• Canada also adopted the QDMTT (Qualified Domestic Minimum Top-up Tax), which means Canada itself collects the top-up tax on undertaxed profits earned within Canada, rather than leaving that revenue for another country to claim.
• The Canada Revenue Agency (CRA) is building out the administrative infrastructure to enforce these rules, including new reporting requirements for affected companies.

For XEQT holders, the Canadian angle matters for a couple of reasons.

First, your Canadian holdings within XEQT (roughly 24% of the portfolio through the XIC component) include some large multinationals that are subject to these rules. Companies like Shopify, Brookfield Asset Management, and Manulife have international operations that could be affected. However, most major Canadian companies already pay effective tax rates at or near the 15% minimum, so the practical impact is limited.

Second, and more interestingly, Canada as a country stands to benefit from the global minimum tax. Canada has a relatively high corporate tax rate by global standards (roughly 26.5% combined federal and provincial). For years, Canadian companies have been at a competitive disadvantage compared to rivals in low-tax jurisdictions. By raising the global floor to 15%, the playing field becomes more level.

There is a broader economic argument here too. Canada’s federal and provincial budgets depend heavily on corporate tax revenue. When multinationals shift profits to tax havens, it reduces the tax base in countries like Canada, putting more pressure on individual taxpayers and small businesses to make up the difference. A global minimum tax helps close that gap.

This is one of those rare policy changes where the long-term economic effects could actually be positive for countries like Canada, even if the short-term headlines feel alarming.

6. Should You Change Your XEQT Strategy?

I have been building up to this question throughout the entire post, and I suspect you already know my answer: no.

But let me explain exactly why, because “no” is not very satisfying on its own.

Here is how I think about whether any news event, policy change, or macroeconomic development should change your investment strategy. I use a simple three-question filter (inspired by the approach I outlined in the financial noise filter):

Question 1: Is this change already priced into the market?

Yes. Pillar Two has been publicly discussed since 2021, agreed to by 140+ countries, and legislated in dozens of jurisdictions including Canada. Every major investment bank, hedge fund, and institutional investor has modeled the impact. When you buy XEQT today, you are buying at a price that reflects this reality. There is no hidden risk here.

Question 2: Does this change affect a concentrated part of my portfolio in a way that creates unacceptable risk?

No. The companies most affected by the global minimum tax represent a subset of XEQT’s technology and pharmaceutical holdings. Even within those sectors, the impact is a modest reduction in after-tax earnings. And those sectors are themselves just a portion of XEQT’s total sector allocation. The diversification across 9,000 stocks, 49 countries, and 11 sectors means no single tax change can create a concentration risk.

Question 3: Does this change alter the fundamental case for owning equities long-term?

Absolutely not. The global minimum tax does not change the fact that owning a diversified basket of the world’s best companies is the most reliable way to build wealth over decades. Companies will continue to innovate, grow revenue, expand into new markets, and generate returns for shareholders. A modest increase in tax rates does not change that fundamental equation.

If you are currently buying XEQT on a regular schedule – whether monthly, biweekly, or whenever you have spare cash – keep doing exactly that. The global minimum tax is interesting. It is worth understanding. But it is not actionable for a passive, long-term investor.

Here is what I told my friend when he texted me that screenshot: “It affects some of the companies you own, but not in a way that matters for your plan. Keep buying. Keep holding. The tax stuff will sort itself out.”

He replied with a thumbs up and, knowing him, went right back to not thinking about his portfolio. Which is exactly the right response.

7. The Bottom Line

Let me pull everything together.

The OECD global minimum tax is a real, meaningful change to the international corporate tax landscape. Over 140 countries, including Canada, have agreed to a 15% minimum corporate tax rate for large multinationals. This closes loopholes that allowed some of the world’s biggest companies – many of which you own through XEQT – to pay effective tax rates in the single digits.

Here is what it means for you as an XEQT investor:

• Some companies in XEQT will pay slightly more in taxes. Primarily large tech and pharma multinationals that relied on low-tax jurisdictions like Ireland, Luxembourg, and Singapore.
• The earnings impact is modest. Estimates suggest a 1-2% reduction in earnings for the most affected companies, diluted further by XEQT’s massive diversification.
• Markets have already priced this in. The global minimum tax has been publicly discussed and legislated for years. There is no surprise impact waiting to hit your portfolio.
• Canada’s adoption of Pillar Two means Canadian multinationals are subject to the same rules. But most large Canadian companies were already paying effective rates at or above 15%.
• Historical precedent is clear. Corporate tax changes happen regularly. Markets adapt. Diversified investors are barely affected.
• The long-term case for XEQT is unchanged. Broad global diversification, low fees, automatic rebalancing, and exposure to the world’s best companies. A 15% tax floor does not change any of that.

If anything, the global minimum tax is a reason to feel more confident in your XEQT strategy, not less. A more level global tax playing field reduces the kind of distortions that can create hidden risks in the system. When every large company is paying at least 15%, the competitive landscape is fairer, government revenues are more stable, and the global economy is arguably on firmer footing.

The world will keep evolving. Tax policies will keep changing. New headlines will keep generating anxiety. But the beauty of XEQT is that you do not need to react to any of it. You own the whole world. The whole world adjusts. And over the long term, it grows.

Keep buying. Keep holding. Let the tax lawyers worry about Pillar Two. You have better things to do with your time.
