That 9% MIC Yield Becomes 4.5% After Tax, Unless You Know This One Move
A $50,000 MIC investment in a taxable account loses $2,250 every year to tax you weren't planning for. Not to poor returns. To tax treatment the marketing materials never explained.
Mortgage Investment Corporations pool private capital to fund residential mortgages, often bridge loans or borrowers who didn't qualify at the big banks. The pitch is straightforward: 9-10% annualized yield, monthly distributions, exposure to real estate without landlord duties. For investors frustrated with 4% GIC rates, the math looks clean.
What the offering memorandum buries in Section 7.2 is that every dollar a MIC distributes is classified as interest income under Section 130.1 of the Income Tax Act. Not dividends. Not capital gains. Interest. Which means you pay tax at your full marginal rate.
The 9% That Isn't
If you're earning $150,000 in Ontario, your marginal rate on the next dollar is roughly 43.5%. In Nova Scotia or Quebec, it pushes past 50%. That 9% headline yield? You keep 4.8% after provincial and federal tax. In British Columbia at the top bracket, you're looking at 4.2%.
A 4.2% net return isn't terrible in isolation. But it's suddenly competing with a Government of Canada 5-year bond yielding 3.1% with zero credit risk, or a high-interest savings account at 4.5% that you can pull out of tomorrow. The MIC's entire premium, the extra yield you're getting paid for taking on private mortgage risk, illiquidity, and no CDIC coverage, has been eaten by the tax structure.
Most investors don't run this math before they write the cheque. The comparison they're making is 9% versus 5%. The comparison they should be making is 4.2% versus 3.1%, and then asking whether the risk spread is worth it.
Why MICs Get Taxed This Way
MICs avoid corporate tax by distributing 100% of net income to shareholders, which keeps the structure efficient for the corporation. The cost of that efficiency lands on you. The distribution is legally interest, and interest is the most expensive type of income in the Canadian tax system, no splitting, no preferential rate, no inclusion-rate discount the way capital gains get taxed on only 50% of the gain (or 66.67% above $250,000, per the 2024 rules).
Private equity funds distribute capital gains. REITs blend return of capital with income. Dividend-paying stocks benefit from the gross-up and credit. MICs give you the one distribution type with zero tax shelter.
The One Account That Fixes It
Inside a TFSA or RRSP, the 9% stays 9%. No withholding, no tax slip, no marginal-rate haircut. The MIC's structure, which punishes you in a taxable account, becomes irrelevant when the account itself is tax-sheltered.
This is the move. If you're holding a MIC, it should be inside registered space. If your TFSA is holding a low-cost equity ETF earning mostly capital gains, and your taxable account is holding the MIC, you've built the portfolio backwards.
The priority rule for tax-efficient portfolio construction is simple: put your highest-taxed assets in the highest-shelter accounts first. Interest income and MICs go in the TFSA and RRSP. Capital-gains-oriented equities go in taxable. Swap them and you're voluntarily paying tax you didn't need to pay.
What This Means for Allocation
Most investors treat their TFSA as "fun money", a place to hold individual stocks, speculative plays, or whatever they're most excited about. That's a $3,500-per-year mistake if the alternative is sheltering a 9% fully-taxable yield.
The TFSA contribution limit for 2025 is $7,000. A 9% yield on $7,000 is $630 annually. In a taxable account at a 47% marginal rate, you keep $334. In the TFSA, you keep $630. The difference, $296 per year, is the tax you pay for holding the wrong asset in the wrong account.
Multiply that across a $50,000 MIC position and the gap is $2,250 per year. Over a decade, that's $22,500 you transferred to CRA because you didn't think about tax treatment when you built the account structure.
The MIC yield isn't the problem. Where you held it is.
