The General Rate Income Pool, or GRIP, is a running balance that a Canadian-controlled private corporation (CCPC) keeps to track how much of its after-tax income was taxed at the full corporate rate rather than the reduced small business rate. That balance sets the ceiling on how much the corporation can pay out as eligible dividends, which carry a larger dividend tax credit on the shareholder’s personal return. GRIP is calculated at the end of each taxation year on Schedule 53 and filed with the T2 return.1Canada Revenue Agency. General Rate Income Pool (GRIP)
Why the Pool Exists
A CCPC pays federal tax at two very different rates. Active business income up to the $500,000 small business limit is taxed at 9 percent federally, while income above the limit is taxed at the general federal rate of 15 percent.2Canada Revenue Agency. Corporation Tax Rates When those earnings are paid out to a shareholder, the personal dividend tax credit has to match the rate the corporation already paid. Otherwise the same dollar gets taxed twice.
GRIP is the ledger that keeps this straight. Earnings taxed at the general rate go into the pool. When the corporation later pays an eligible dividend out of that pool, the shareholder claims the larger, enhanced dividend tax credit. Earnings taxed at the small business rate stay out of the pool and can only be paid out as ordinary (non-eligible) dividends, which carry a smaller credit. Without this tracking, there would be no way to tell which dollars leaving the corporation had already borne which level of tax.
What Goes Into the Calculation
Section 89(1) of the Income Tax Act defines GRIP using an A minus B formula that runs cumulatively year over year.3Department of Justice. Income Tax Act – Section: Definitions The A side pulls together five inputs:
- The prior year’s closing GRIP balance, carried forward as the opening balance.
- The corporation’s adjusted taxable income for the current year multiplied by the general rate factor of 0.72. This captures the portion of current-year income taxed at the full rate.
- Eligible dividends received from other corporations, plus amounts deductible under Section 113 for certain foreign affiliate income.
- Adjustments arising from amalgamations, wind-ups, and other reorganizations under subsections 89(4) through 89(6).
- Eligible dividends paid in the preceding year, subtracted. This drains the pool as the corporation distributes its high-taxed earnings.
The B side is a clawback that adjusts for changes in the corporation’s full-rate taxable income over the preceding three years. For most CCPCs with stable income, B is zero. Corporations that go through reassessments or reclassifications of income need to watch it, because the adjustment is meant to prevent retroactive manipulation of the balance.
What Feeds Into GRIP and What Does Not
Only income taxed at the general corporate rate feeds the pool. The clearest example is active business income above the $500,000 small business deduction limit.4Canada Revenue Agency. Small Business Deduction Rules Eligible dividends received from connected or other corporations also increase the balance, because those amounts already imply full-rate taxation at the paying corporation.
Income eligible for the small business deduction stays out. Investment income earned inside a CCPC follows separate refundable tax rules and generally does not flow through GRIP the same way. Getting this separation wrong is where most GRIP errors start: a corporation that claims the small business deduction on income and then treats it as general-rate income in the calculation will end up over-designating eligible dividends.
Filing Schedule 53
The CRA requires the calculation to be reported on Schedule 53 (General Rate Income Pool Calculation), filed with the T2 Corporation Income Tax Return. The T2 is due within six months of the corporation’s fiscal year-end.5Canada Revenue Agency. When to File Your Corporation Income Tax Return The CRA asks corporations to file Schedule 53 in any year the corporation paid an eligible dividend or the GRIP balance changed, so its records stay aligned with the corporation’s.
Because the balance is cumulative, the closing figure from one year becomes the opening figure for the next. An error in any single year compounds forward. The balance itself is calculated at year-end, but eligible dividends can be paid throughout the year as long as the year-end pool supports the total paid, which means some estimation is unavoidable during the year and Schedule 53 acts as the true-up.
Designating Eligible Dividends
A positive GRIP balance is not enough on its own. To pay an eligible dividend, the corporation has to designate it as such before or at the time the dividend is paid, and it has to notify shareholders in writing.6Canada Revenue Agency. Designation of Eligible Dividends Without a proper designation and written notice, the dividend defaults to a non-eligible dividend and shareholders lose the enhanced credit.
The CRA accepts several forms of written notice: letters to shareholders confirming eligible status, dividend cheque stubs stating that the dividend is eligible, and a notation in the corporate minutes where all shareholders are also directors. Public corporations have wider options, including a standing notice on the corporate website or a statement in quarterly and annual reports. For a private corporation, the safer route is a statement on the cheque stub or a separate letter at the time of payment. Corporate minutes work only in the narrow case where every shareholder sits on the board.
What Shareholders Actually Get
The reason for all this bookkeeping shows up on the personal return. An eligible dividend is grossed up by 38 percent, so a $1,000 eligible dividend is reported as $1,380 of taxable income. The shareholder then claims a federal dividend tax credit of 15.0198 percent of the grossed-up amount, roughly $207 on that $1,000 dividend. A non-eligible dividend, by contrast, is grossed up by 15 percent and carries a federal credit of 9.0301 percent of the grossed-up amount.
The larger credit on eligible dividends is not a bonus. It reflects the higher corporate tax already paid on the underlying earnings. In a fully integrated system, the combined corporate and personal tax on a dollar of corporate profit equals the personal tax the shareholder would have paid if they had earned that dollar directly. GRIP keeps that integration honest by tying the enhanced credit to earnings that genuinely bore the full corporate rate.
Penalty for Paying Out More Than the Pool Supports
If a corporation designates more eligible dividends than its GRIP balance can support, the excess is an excessive eligible dividend designation and triggers Part III.1 tax under Section 185.1 of the Income Tax Act. The tax is 20 percent of the excess.7Canada Revenue Agency. Part III.1 Tax An additional 10 percent applies where the excessive designation falls within paragraph (c) of the definition, bringing the potential total on that portion to 30 percent.8Department of Justice. Income Tax Act – Section 185.1 The tax is due on or before the corporation’s balance-due day for the year the over-designation occurred, and it often surfaces only when the CRA reassesses, by which point interest has been running.
Correcting an Over-Designation
Section 185.1(2) provides a relief election. The corporation can elect to treat the excessive portion as an ordinary (non-eligible) dividend from the outset.8Department of Justice. Income Tax Act – Section 185.1 If the election is accepted, the Part III.1 tax goes away, but shareholders have to refile their personal returns to reflect a smaller eligible dividend and a larger ordinary dividend.
The election has to be filed within 90 days of the notice of assessment for the Part III.1 tax. It also requires the concurrence of all shareholders who received the original dividend and whose addresses are known to the corporation. Concurrence has to be obtained within 30 months of the date the dividend became payable, unless every affected shareholder explicitly agrees, in which case the CRA can reassess them outside the normal time limits.9Department of Justice. Income Tax Act – Section 184 For a closely held CCPC with a few shareholder-directors, this is manageable. For a corporation with many arm’s-length shareholders, it can be enough of a logistical problem to make the election impractical.
Associated Corporations Each Keep Their Own Pool
Associated CCPCs share the $500,000 business limit for the small business deduction, and that sharing feeds directly into each corporation’s GRIP. A corporation that receives a larger slice of the shared limit has more income taxed at the low rate and less flowing into its pool. The others in the group, with less of the limit, see more income taxed at the general rate and their pools grow faster. Each associated corporation keeps its own separate GRIP account. There is no consolidated group balance, so the allocation of the business limit directly determines which entity can pay eligible dividends and how much.
When CCPC Status Changes
GRIP only matters while the corporation is a CCPC or a deposit insurance corporation. If a CCPC loses its Canadian-controlled status, it moves from the GRIP regime to the Low Rate Income Pool (LRIP) regime, which tracks low-rate income and penalizes excess non-eligible dividends instead.
A CCPC can also elect voluntarily under Section 89(11) to be treated as a non-CCPC for eligible dividend purposes by filing Form T2002, which moves it from GRIP rules to LRIP rules.3Department of Justice. Income Tax Act – Section: Definitions The election tends to make sense only for corporations whose income is essentially all taxed at the general rate, since any future small-business-rate income would create LRIP problems.
Common Mistakes That Distort the Balance
Corporations often skip filing Schedule 53 in years when no eligible dividends were paid. The schedule is meant to be filed whenever the balance changed, not only when dividends went out. Skipping years lets the CRA’s records drift from the corporation’s, and the mismatch typically shows up as a discrepancy the next time an eligible dividend is designated.
Misapplying the 0.72 general rate factor is another recurring problem. The factor applies to adjusted taxable income, not to gross revenue or unadjusted net income. Using the wrong figure inflates or deflates the annual addition, and over several years the compounded error can be material.
The third common slip is forgetting that the formula subtracts prior-year eligible dividends, not current-year ones. A corporation that paid large eligible dividends last year but does not carry that reduction through to this year’s opening balance will overstate the pool. A year-over-year reconciliation is the only reliable way to catch these errors before a reassessment finds them.
