Part One
The Capital Dividend Account (CDA)
When your Canadian private corporation sells an investment for a capital gain, Canada's tax system only taxes a portion of that gain as income. The rest — the non-taxable portion — doesn't just disappear. It accumulates in a special notional account called the Capital Dividend Account (CDA).
The remarkable thing about the CDA: when you pay a capital dividend to shareholders from this balance, those shareholders receive it completely tax-free. No personal income tax. No dividend tax. Nothing.
The CDA exists because of a principle called tax integration — Canada's tax system tries to ensure that income earned through a corporation ends up taxed at roughly the same overall rate as income earned personally. Since only part of a capital gain is ever taxed, that untaxed part should flow through to you untaxed as well.
Plain language summary: Think of the CDA as a tax-free piggy bank inside your corporation. Every time your corp sells something at a profit — shares, ETFs, real estate — a portion of that gain fills the piggy bank. You can crack it open at any time and take the money out completely tax-free, as long as your accountant files the right election with CRA.
How It Works
What adds to your CDA balance
The CDA is a cumulative account — it builds up over time from multiple sources, with no expiry date on the balance.
- Capital gains: The non-taxable portion of capital gains realized by the corporation. This is the primary source for most investors.
- Life insurance proceeds: The death benefit received on a corporate-owned life insurance policy, minus the policy's Adjusted Cost Basis (ACB). This can create very large CDA balances.
- Capital dividends received: If your corp receives a capital dividend from another private corporation, that amount flows into your CDA.
- Trust distributions: Certain tax-free amounts from trusts in which the corporation holds units.
Inclusion rate confirmed at 50% — capital gains hike cancelled: The capital gains inclusion rate for corporations is 50%. This means 50% of any capital gain goes into your CDA — tax-free to shareholders.
The 2024 budget proposed raising the corporate inclusion rate to 66.7% (which would have reduced the CDA credit to 33.3%). That proposal was cancelled by PM Carney on March 21, 2025 and never became law.
Transitional period caveat: If your corporation realized capital gains between June 25, 2024 and early 2025, those may have been filed at the 66.7% rate while the proposal was being administered by CRA. Ask your accountant to confirm how those gains were treated and whether any CDA adjustment is warranted.
Example
How CDA works — a worked example
Your corporation sells an equity ETF position for a $100,000 capital gain. Here's exactly what happens at the confirmed 50% inclusion rate:
Capital gain realized
$100,000
Taxable in corp (50% inclusion)
$50,000
Flows into CDA (non-taxable 50%)
$50,000
CDA dividend paid to shareholder
$50,000
Personal tax on that dividend

A clean 50/50 split — half goes to the taxman inside the corp, half flows to your CDA to be paid out tax-free whenever you choose. Your accountant maintains a running CDA ledger from your corporate returns; ask for the current balance if you don't already know it.
Accumulation over time: The CDA is cumulative. If your corporation has been investing for years and selling positions periodically, your CDA balance may be much larger than you realize. Each sale that resulted in a capital gain added to the balance. Ask your accountant for the current CDA balance — it's one of your most valuable tax-free resources.
Rules
Important CDA rules and process
- Tax-free to Canadian-resident shareholders. Capital dividends are received completely free of personal income tax by shareholders resident in Canada.
- No expiry. CDA balances carry forward indefinitely. A gain realized in 2015 can still be paid out tax-free in 2035.
- Can be paid to any share class. If your corporation has multiple share classes, review your articles of incorporation to confirm which classes are eligible for capital dividends.
- Must file Form T2054 with CRA. The election must be filed at or before the time the dividend becomes payable. Miss this and it becomes a taxable dividend.
- Cannot exceed the CDA balance. If you pay a capital dividend exceeding your actual CDA balance, CRA assesses Part III tax at 60% of the excess amount — a severe penalty.
- Non-residents face withholding tax. Capital dividends paid to non-resident shareholders are subject to 25% withholding tax (reduced by tax treaty in some cases).
- Accountant must track CDA carefully. The CDA is a notional account — CRA doesn't send you a statement. Your accountant calculates and maintains it from corporate tax returns.
Part Two
Refundable Dividend Tax on Hand (RDTOH)
Canadian private corporations pay a very high tax rate on passive investment income — interest, foreign dividends, and certain other income. Federally, the rate is approximately 38.7%. Combined with provincial tax, effective rates can approach 50%.
Without any corrective mechanism, this creates double taxation: the corporation pays ~50% tax on its passive income, and then when it pays out dividends, shareholders pay personal tax on top of that.
RDTOH prevents this. It works as a prepaid tax refund system: the corporation pays the high tax upfront, but CRA credits a portion of that tax to the RDTOH account. When the corporation pays taxable dividends to shareholders, CRA refunds that prepaid tax back to the corporation — because the income is now being taxed in the shareholder's hands instead.
The refund rate: 38.33 cents for every dollar of taxable dividends paid, up to the RDTOH balance. Think of RDTOH as a CRA IOU to your corporation — collected when you pay yourself dividends.
Structure
Two types of RDTOH (since 2019)
Since 2019, RDTOH is split into two separate accounts. The distinction matters because each type is only refunded when a specific kind of dividend is paid.
| Type |
What generates it |
Refunded when corp pays |
Typical sources |
| Eligible RDTOH |
Eligible dividends received from non-connected Canadian corporations |
Eligible dividends |
Canadian stocks and ETFs (TD, ENB, XIU, etc.) |
| Non-eligible RDTOH |
Interest income, foreign dividends, and other passive investment income |
Non-eligible dividends first |
GICs, bonds, US ETFs, foreign stocks |
Critical ordering rule: When you pay dividends, non-eligible RDTOH must be exhausted first before eligible RDTOH can be accessed. This affects which type of dividend is most tax-efficient to pay in any given year. Your accountant needs to model this based on your actual RDTOH balances before deciding on dividend type and amount.
Example
How RDTOH works — a worked example
Your corporation earns $10,000 in interest from a GIC. Here's how RDTOH works on that income:
Interest income earned
$10,000
Corp tax paid (~50.17% in ON)
~$5,017
Added to Non-eligible RDTOH
$3,067
Corp pays non-eligible dividend
$8,000 paid
CRA refunds to corp (38.33% × $8,000)
$3,067 back
You pay personal tax on $8,000 dividend
~$2,400 (est.)
The end result: the income has been taxed once — at your personal marginal rate — not twice. The corporate tax was a prepayment that got refunded when the money moved to your hands.
Part Three
How they work together at retirement
CDA and RDTOH don't work in isolation — at retirement, your accountant will coordinate all the levers together to maximize after-tax income. Here's how a typical retirement extraction year works when all three pools are in play.
Strategy
The retirement extraction sequence
Here's the recommended order for drawing down corporate accounts at retirement to minimize tax:
Step 1: Capital dividend from CDA
Pay from CDA balance. File Form T2054 election with CRA before declaring. Received completely tax-free.
Step 2: Non-eligible dividends (drain Non-eligible RDTOH first)
Pay non-eligible dividends to exhaust $RDTOH. Corp receives refund from CRA. You pay ~30% personal tax on dividends received.
Step 3: Eligible dividends (drain Eligible RDTOH)
Pay eligible dividends to trigger RDTOH refund to corp. You pay ~25% personal tax on eligible dividends — the most tax-efficient taxable dividend.
Step 4: Additional eligible dividends from retained earnings
Remaining funds drawn as eligible dividends from general retained earnings. Personal tax applies with no further RDTOH refund available.
Net result of coordinated extraction: Of $120,000 extracted: $80,000 came out tax-free via CDA. The remaining $40,000 was taxed at personal rates on eligible dividends (~25%), with RDTOH refunds flowing back into the corporation. Effective blended tax rate on the full $120,000: approximately 8–10% vs. 25%+ without the CDA.
This is the power of building corporate investment wealth over time — and why the CDA balance deserves careful attention from both you and your accountant, every year.
Legislation
Current tax rules and legislative status
Capital gains inclusion rate — confirmed at 50%: The proposed increase to 66.7% was cancelled by PM Carney on March 21, 2025. The corporate inclusion rate is 50% going forward. CDA credits continue to equal 50% of capital gains. If you had gains filed at 66.7% during the transitional period (June–Dec 2024), verify with your accountant how those were treated.
Bill C-15 received Royal Assent — March 26, 2026: Budget 2025 legislation is now law. This implements SR&E enhancements, accelerated CCA measures, and various clean economy tax credits. The RDTOH dividend suspension rules were not included in Bill C-15 — they were released separately as draft legislation on January 29, 2026.
RDTOH dividend suspension rules — still draft as of April 2026: As of March 31, 2026, the dividend suspension rules have not been tabled as a bill in the House of Commons and are not yet law. They remain draft proposals effective for tax years beginning after November 4, 2025.
These rules primarily affect tiered corporate structures where dividends flow between affiliated private corporations with misaligned year-ends before reaching individual shareholders. If your corp pays dividends directly to yourself as an individual, you are likely not affected. If you have a holding company structure, speak with your accountant before acting.
No spring 2026 federal budget has been tabled as of this update (April 2026).
