Key Takeaways
- 1.After June 25, 2024, the first $250,000 in annual net capital gains for individuals is still included at 1/2 (50%). Gains above $250K are included at 2/3 (66.67%).
- 2.Gains realized before June 25, 2024 are fully grandfathered at the 1/2 rate — the disposition date (trade date), not the settlement date, determines the rate.
- 3.A Manitoba investor with $500K total gains in a single year pays tax on $291,667 of taxable income instead of $250,000 under the old flat 1/2 rate — an extra $41,667 in taxable income.
- 4.Splitting $500K across two tax years (realizing $250K in each year) keeps the entire amount at the 1/2 rate, saving roughly $9,000 in Manitoba tax.
- 5.Corporations have no $250K threshold — all gains after June 25, 2024 are included at 2/3, making personal realization more tax-efficient for gains under the threshold.
The June 25, 2024 Inclusion Rate Change: What Actually Happened
On June 10, 2024, the federal government confirmed the capital gains inclusion rate increase, effective for dispositions on or after June 25, 2024. The change introduced a two-tier system for individuals:
- First $250,000 in annual net capital gains: included at 1/2 (50%) — unchanged
- Above $250,000: included at 2/3 (66.67%)
For corporations and trusts, there is no $250,000 threshold. All capital gains realized on or after June 25, 2024 are included at 2/3. This is a critical distinction for investors who hold assets inside a holding company — the math is fundamentally different. For how corporate income structuring works more broadly, see our corporation salary vs. dividend calculator.
Which Gains Are Grandfathered at 1/2?
Any capital gain with a disposition date before June 25, 2024 is permanently locked at the 1/2 inclusion rate. The key rules:
- Publicly traded securities: the trade date (T) is the disposition date, not the settlement date (T+1). A sale executed on June 24, 2024 is grandfathered even though settlement occurred on June 25.
- Real property: the disposition date is generally the date the purchase and sale agreement becomes binding (not the closing date), unless the agreement specifies otherwise.
- Private company shares: the disposition date is when the sale agreement is executed and all conditions precedent are met.
For our Manitoba investor with $500K in total gains, the first question is: how much was disposed of before June 25, 2024? This determines the grandfathered portion.
Worked Example: $500K Gains, Manitoba Investor
Here is the scenario. A Manitoba individual has a diversified portfolio and realized $500,000 in total capital gains during the 2024–2025 period. Assume the following split:
- $150,000 realized before June 25, 2024 (grandfathered at 1/2)
- $350,000 realized on or after June 25, 2024 (subject to the new tiered rate)
Step 1: Grandfathered Gains (Pre-June 25, 2024)
The $150,000 in pre-June 25 gains is included at 1/2 regardless of the annual threshold. Taxable capital gain = $150,000 × 50% = $75,000.
Step 2: Post-June 25 Gains and the $250K Threshold
The $350,000 in post-June 25 gains is subject to the tiered system. The $250,000 threshold applies to the full tax year's net capital gains (including the grandfathered portion). Since the investor already has $150,000 in gains for the year, only $100,000 of the post-June 25 gains falls under the $250K threshold.
| Component | Gains | Inclusion Rate | Taxable Amount |
|---|---|---|---|
| Pre-June 25 gains (grandfathered) | $150,000 | 1/2 (50%) | $75,000 |
| Post-June 25 — within $250K threshold | $100,000 | 1/2 (50%) | $50,000 |
| Post-June 25 — above $250K threshold | $250,000 | 2/3 (66.67%) | $166,667 |
| Total taxable capital gains | $291,667 | ||
Under the old uniform 1/2 rate, the same $500,000 in gains would produce $250,000 in taxable income. The new system adds $41,667 to the taxable amount — a 16.7% increase in inclusion.
Manitoba Combined Marginal Rates at Each Inclusion Tier
Manitoba's provincial tax rates interact with the federal brackets to produce the combined marginal rate on the included portion of capital gains. Here are the effective capital gains rates at key Manitoba income levels for 2025:
| Taxable Income Bracket | Combined Marginal Rate | Effective CG Rate (1/2) | Effective CG Rate (2/3) |
|---|---|---|---|
| $0–$47,000 | 25.80% | 12.90% | 17.20% |
| $47,001–$57,375 | 27.75% | 13.88% | 18.50% |
| $57,376–$100,000 | 33.25% | 16.63% | 22.17% |
| $100,001–$106,730 | 37.90% | 18.95% | 25.27% |
| $106,731–$165,430 | 43.40% | 21.70% | 28.93% |
| $165,431–$235,675 | 46.40% | 23.20% | 30.93% |
| $235,676–$355,845 | 49.40% | 24.70% | 32.93% |
| $355,846+ | 50.40% | 25.20% | 33.60% |
Combined federal + Manitoba provincial rates for 2025. The jump from the 1/2 column to the 2/3 column is roughly 4–8 percentage points depending on the bracket — a material difference on six-figure gains.

Tax Bill on the $500K Gain: Single-Year vs. Split-Year
Let's calculate the actual Manitoba tax difference between realizing all $500,000 in a single year versus splitting it across two tax years. Assume no other income for simplicity (the investor lives on capital gains and has no employment income).
| Scenario | Taxable CG Income | Approx. Tax (Fed + MB) | Tax Savings vs. Single Year |
|---|---|---|---|
| All $500K in one year | $291,667 | ~$89,500 | — |
| $250K in Year 1, $250K in Year 2 | $125,000 × 2 | ~$80,200 | ~$9,300 |
| $200K in Year 1, $300K in Year 2 | $100K + $166,667 | ~$84,100 | ~$5,400 |
Estimates use 2025 federal and Manitoba brackets. The even $250K/$250K split is optimal because it maximizes use of the 1/2 inclusion threshold in both years. Any uneven split wastes threshold room in one year and overflows into the 2/3 rate in the other.
The $9,300 tax saving from splitting evenly is real money — it comes entirely from keeping the full $500,000 at the 1/2 inclusion rate instead of pushing $250,000 into the 2/3 tier. This is the single most valuable planning opportunity created by the June 25, 2024 change for investors with large unrealized gains.
Sequencing Dispositions to Maximize the Lower-Rate Bucket
The order in which you sell assets does not change the inclusion rate (the CRA does not apply gains on a first-in-first-out basis against the $250K threshold). What matters is the total net capital gains for the tax year. However, sequencing still matters for two reasons:
- Tax-year boundary: Dispositions in December vs. January fall into different tax years, allowing you to use the $250K threshold twice.
- Loss offsets: Realizing capital losses in the same year as gains reduces net gains, potentially keeping you under the $250K threshold. For a detailed walkthrough of tax-loss harvesting mechanics, see our tax-loss harvesting calculator.
For the Manitoba investor with $500K in unrealized gains across multiple holdings, the optimal strategy is:
- Realize up to $250,000 in net gains before December 31 of the current tax year.
- Harvest any available capital losses in the same year to offset gains and free up threshold room.
- Realize the remaining gains in January of the following year, resetting the $250K threshold.
- If gains exceed $500K total, continue spreading across additional tax years at $250K per year.
Corporate vs. Personal: Which Is Better for $500K in Gains?
The elimination of the $250K threshold for corporations is the most significant structural difference in the new rules. Here is a direct comparison for the same $500,000 gain:
| Factor | Personal | Corporate (Manitoba CCPC) |
|---|---|---|
| $250K threshold | Yes — first $250K at 1/2 | No — all at 2/3 |
| Taxable capital gain on $500K | $291,667 | $333,333 |
| Corporate tax rate (investment income) | n/a | ~50.67% (refundable) |
| Immediate tax on $500K gain | ~$89,500 | ~$168,900 (before RDTOH refund) |
| After dividend extraction | $89,500 (final) | ~$90,800 (after RDTOH refund + dividend tax) |
| Deferral advantage | None | Yes — if you don't extract immediately |
Corporate rates assume a Manitoba CCPC with passive investment income. The refundable dividend tax on hand (RDTOH) mechanism refunds roughly 30.67% of the corporate tax when eligible dividends are paid. The total after-all-tax cost is designed to be roughly equivalent (integration), but imperfect integration means the corporate route is slightly more expensive on a fully-extracted basis.
The corporate route only wins if you leave the money inside the corporation for extended periods, deferring the personal dividend tax. For a Manitoba investor who needs the $500K in cash within a year or two, personal realization is almost certainly cheaper — the $250K threshold alone saves roughly $18,000 in taxable income compared to the corporate all-at-2/3 treatment. For investors considering the lifetime capital gains exemption on a business sale, the personal route also provides access to the enhanced LCGE.
Optimal Timing: A Complete Worked Example
Here is the full sequence for our Manitoba investor to minimize tax on the $500,000 portfolio gain, assuming all dispositions occur after June 25, 2024 and the investor has no other income:
| Action | Timing | Gains Realized | Taxable CG |
|---|---|---|---|
| Sell holdings with $250K gains | Before Dec 31, 2025 | $250,000 | $125,000 (at 1/2) |
| Harvest $30K in losses (if available) | Before Dec 31, 2025 | −$30,000 | −$15,000 |
| Sell additional $30K in gains (replaces loss offset) | Before Dec 31, 2025 | $30,000 | $15,000 (at 1/2) |
| Sell remaining $250K in gains | After Jan 1, 2026 | $250,000 | $125,000 (at 1/2) |
| Total taxable capital gains (over two years) | $250,000 | ||
By splitting $500K across two years at $250K each, the entire amount stays at the 1/2 inclusion rate. The loss-harvesting step creates room to realize an additional $30K in gains within the $250K threshold, effectively “squeezing” more gains into the lower tier. Net gains in Year 1: $250K ($280K gains minus $30K losses). Net gains in Year 2: $250K. For cottage or real estate dispositions that involve larger single-asset gains, see our cottage capital gains calculator.
The LCGE Interaction: Why Business Owners Get Extra Room
The lifetime capital gains exemption (LCGE) for qualified small business corporation shares was increased to $1,250,000 effective June 25, 2024 (from $1,016,836). LCGE-eligible gains are fully exempt from tax and do not count against the $250,000 threshold. This means a Manitoba business owner selling a qualified business for $1.5 million could shelter $1.25 million under the LCGE and only $250,000 would be subject to capital gains inclusion — all within the 1/2 rate threshold.
For portfolio investors without LCGE-eligible shares, this does not apply. But if you hold shares in an active business alongside your investment portfolio, coordinate the business sale with your portfolio disposition plan to avoid exceeding the $250K threshold on the non-exempt portion.
Common Mistakes to Avoid
- Assuming the $250K threshold is per-asset: It is per-taxpayer, per-year. Five separate $60K gains in one year total $300K, and $50K is included at 2/3.
- Forgetting that the threshold includes all gains: Real estate, securities, and other capital property all count toward the same $250K annual limit.
- Ignoring superficial loss rules when harvesting: If you repurchase the same or identical security within 30 days (before or after the sale), the loss is denied. Use a substitute security or wait 31 days.
- Using the corporate route for gains under $250K: Without the threshold, corporations include every dollar at 2/3. For sub-$250K gains, personal realization is almost always cheaper.
- Missing the December 31 trade-date cutoff: For year-end splitting, the trade must execute on or before December 31. Orders placed after market close on December 31 execute on January 2 and fall into the next tax year.
