Holding company tax in Canada: Opco dividends go up free under s.112

What tax applies to each dollar that moves through a holding company?

A holding company doesn't get a special rate. It's an ordinary corporation, and the tax depends on what kind of income it receives. Dividends from a taxable Canadian corporation, or from a resident corporation it controls, are deductible in computing its taxable income under s.112(1) laws-lois.justice.gc.ca. Part IV tax then decides whether any of that dividend is taxed for now laws-lois.justice.gc.ca.

Connected means Holdco controls the payer, or owns more than 10% of its voting shares and shares worth more than 10% of the value of all its issued shares laws-lois.justice.gc.ca. For that control test, s.186(2) counts shares held by persons who don't deal at arm's length with Holdco. The deduction and its exceptions are on the intercorporate dividends page, and the Part IV arithmetic is on the Part IV tax page.

Part IV and the refundable tax on investment income aren't permanent. Holdco gets a dividend refund of 38 1/3% of the taxable dividends it pays, capped by its RDTOH pools, as long as it files the T2 within 3 years after the year end laws-lois.justice.gc.ca. The 10 2/3% addition comes from s.123.3 laws-lois.justice.gc.ca. The pools are explained on the RDTOH page.

What tax is due when Opco pays Holdco a $300,000 dividend?

Your client owns all the shares of Holdco, and Holdco owns all the shares of Opco, a CCPC. Opco earns $500,000 of active business income and has no investment income, so its RDTOH is nil. Opco pays Holdco a $300,000 non eligible dividend. Federal figures only.

The 9% is the CRA's net federal rate for a CCPC on income eligible for the small business deduction canada.ca. Change one fact: Opco also earned interest and had $20,000 of non eligible RDTOH. Its refund becomes the lesser of $115,000 and $20,000, so $20,000, and Holdco owes $20,000 of Part IV tax (its whole share, because it received the whole dividend) laws-lois.justice.gc.ca. Holdco gets that back at 38 1/3% of the dividends it later pays from that pool: $52,173.91 of dividends ($20,000 ÷ 38 1/3%) releases all of it laws-lois.justice.gc.ca.

The step that still needs checking is s.55(2). It reaches a dividend received by a Canadian resident corporation and deductible under s.112, where one purpose is a significant reduction in the capital gain on a share, and only to the extent the dividend exceeds the income earned or realized after 1971 that could reasonably contribute to that gain laws-lois.justice.gc.ca. If Opco's safe income on hand covers the $300,000, nothing is recharacterized. If it doesn't and the purpose test is met, the excess becomes a capital gain for Holdco. The calculation is on the section 55(2) safe income page.

How does a holding company keep Opco shares eligible for the LCGE?

Selling qualified small business corporation shares lets your client use the lifetime capital gains exemption. At the sale, Opco has to be a small business corporation: a CCPC with 90% or more of the fair market value of its assets used mainly in an active business carried on primarily in Canada, or in shares or debt of connected small business corporations canada.ca. Throughout the 24 months before the sale, more than 50% of the value has to pass the same asset test laws-lois.justice.gc.ca.

Surplus cash and portfolio investments sitting in Opco fail those tests. Paying them up to Holdco as a dividend (purifying) removes them from Opco, and the dividend itself is covered by the table above. Do it early: the 50% test looks back over the full 24 months, so a purification dividend the week before a sale fixes only the 90% test.

Two traps in a Holdco structure. First, if your client sells the Holdco shares rather than the Opco shares, Holdco has to pass the tests itself, and the cash you moved into Holdco now counts against its 90%. Second, paragraph (d) of the definition tightens the 50% test for a chain: for any period in the 24 months when a corporation doesn't have all or substantially all of its value in qualifying assets, "more than 50%" is read as "all or substantially all" for each connected corporation in that period laws-lois.justice.gc.ca.

The exemption is $1.25 million of gains for dispositions after June 24, 2024 and before 2026, and indexation resumes in 2026 canada.ca. The indexed 2026 figure and how to claim it are on the lifetime capital gains exemption 2026 page.

Holdco and Opco share one $500,000 limit, and Holdco's investments shrink it

Holdco controls Opco, so the two are associated under s.256(1)(a) laws-lois.justice.gc.ca. Associated CCPCs get one $500,000 business limit between them, allocated by an agreement under s.125(3); without one, each corporation's limit is nil laws-lois.justice.gc.ca. Shares a holding company owns are also deemed owned by its shareholders in proportion to value under s.256(1.2)(d), which is how a Holdco can associate Opco with your client's other companies. The full tests are on the associated corporations page.

The passive income grind follows the group. Section 125(5.1)(b) reduces the business limit by 5 × (adjusted aggregate investment income − $50,000), scaled by the limit over $500,000, using the investment income of the corporation and every associated corporation for taxation years that ended in the preceding calendar year laws-lois.justice.gc.ca. Only the greater of this and the taxable capital grind applies.

The table assumes Opco earns at least $500,000 of active business income and has under $10 million of taxable capital. The 15% and 9% are the CRA's net federal general and small business rates canada.ca. Taxable capital gains on active assets are left out of adjusted aggregate investment income laws-lois.justice.gc.ca. The rest of the definition is on the passive income grind page, and the provincial rates are on the small business deduction 2026 page.

Can Holdco claim GST/HST input tax credits on costs for its subsidiary?

Yes, under s.186 of the Excise Tax Act, if Holdco is a GST/HST registrant resident in Canada and the subsidiary is its operating corporation laws-lois.justice.gc.ca. An operating corporation is one related to Holdco where all or substantially all of its property was last acquired, made or imported for use exclusively in its commercial activities (s.186(0.2)).

When that holds, s.186(1) treats Holdco's costs as used in its commercial activities to the extent they relate to buying, holding or selling the operating corporation's shares or debt, or to raising money that Holdco passes down to the operating corporation for its commercial activities laws-lois.justice.gc.ca. Section 186(2) gives the same result for costs of acquiring all or substantially all of a target's voting shares, where the target's property is substantially all used in commercial activities. A Holdco over a subsidiary whose property is used mainly to make exempt supplies fails the operating corporation test and loses those credits.
