Owners end up with extra corporations for many reasons: an acquisition, a reorganized practice, or a structure that has outlived its purpose. Each extra corporation means another return every year for no benefit. The two standard ways to reduce the count, an amalgamation and a wind-up, are not interchangeable. ## Amalgamation: two become one An amalgamation merges two or more taxable Canadian corporations into one new corporation. Section 87 treatment requires, among other conditions, that all property of the predecessors (other than amounts receivable from, or shares of, another predecessor) and all liabilities pass to the new corporation, and that the shareholders of the predecessors receive its shares. The predecessors do not survive. In a Canadian amalgamation, that is the trade-off: the tax attributes carry over, but the predecessor corporations themselves are gone. **Two or more corporations to simplify?** We handle the final returns, the deemed year-ends and the T2s on both sides of an amalgamation or wind-up, with the whole job quoted in writing first.

A subsidiary distributes its property to its parent and is dissolved; the parent carries on. There is no new entity. The T2 return asks about this directly — per the CRA’s [T2 guide](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4012/t2-corporation-income-tax-guide-chapter-1-page-1-t2-return.html), line 072 asks whether there has been a wind-up of a subsidiary under section 88 during the tax year. **A wind-up is not the same as a dissolution.** Collapsing a subsidiary into a parent under section 88 is a reorganization. Shutting a corporation down entirely is a different transaction with different filings. See our guide to [dissolving a corporation](https://www.everstonecpa.com/blog/dissolving-a-corporation-canada). ## The filing differences that catch people out The compliance consequences are where the two routes diverge most visibly: - **Predecessor returns.** On an amalgamation, each predecessor must file a return for the period ending *immediately before* the effective date of amalgamation, and answers “yes” at line 076. The CRA states it cannot accept returns filed for a period ending just before a date that is not the effective date, so the corporate paperwork and the tax filings have to agree. - **The new corporation’s first year.** The tax year of the new corporation cannot be longer than 53 weeks from the date of amalgamation. Line 071 flags the first filing after an amalgamation. - **Schedule 24.** Both a first filing after amalgamation and a wind-up of a subsidiary require Schedule 24 to be filed, and the CRA warns that omitting it may delay processing. - **Effective date.** The effective date of an amalgamation is governed by corporate law, generally the date on the certificate of amalgamation. You do not get to pick it after the fact. ## How to think about choosing The choice usually turns on the shape of the group, not a tax rate. A wind-up works only where one corporation owns the other, so it suits collapsing a redundant subsidiary or unwinding part of a [holding company](https://www.everstonecpa.com/blog/holding-company-canada-when-it-makes-sense) structure. Amalgamation suits sibling corporations owned by the same people. Beyond that, the analysis is about attributes. Loss carryforwards, capital dividend account balances, refundable tax balances, cost bases, [capital cost allowance](https://www.everstonecpa.com/blog/capital-cost-allowance-cca-classes-canada) pools and reserve positions all follow rules that depend on which route is used and on the timing of the year-ends created. Two corporations with clean balance sheets and no losses are a straightforward decision. Add accumulated losses, differing fiscal year-ends, or debt between the companies, and the route changes the outcome by real amounts. ## The costs that are easy to forget Both routes carry non-tax work: corporate filings with the incorporating jurisdiction, updated minute books, notifying the CRA, moving payroll and GST/HST accounts, re-papering bank facilities and contracts that name a specific entity, and dealing with a short tax year and its [year-end implications](https://www.everstonecpa.com/blog/corporate-fiscal-year-end-canada-how-to-choose). Simplifying a group is worth doing, but the year you do it is the year with more compliance, not less. The amalgamation CRA filings that catch people out are set out in the filing differences section above. ## The bottom line Both routes combine corporations without an immediate tax cost, but they produce different entities, year-ends and filing obligations, and they interact differently with each corporation’s tax attributes. The right one depends on your balance sheets and ownership chain, so take the actual numbers to a CPA and a corporate lawyer before the corporate steps are filed.

A wind-up under section 88 collapses a subsidiary into its parent: the subsidiary’s property goes to the parent, the subsidiary is dissolved, and no new entity is created. **Do the old corporations still have to file returns after an amalgamation?** Yes. Each predecessor corporation has to file a return for the period ending immediately before the effective date of amalgamation and answer yes at line 076 of the T2. The CRA states it cannot accept returns filed for a period ending just before a date that is not the effective date. **How long can the first tax year after an amalgamation be?** The CRA’s T2 guide states that the tax year of a new corporation cannot be longer than 53 weeks from the date it was amalgamated. The first filing after an amalgamation is flagged at line 071 of the [T2 return](https://www.everstonecpa.com/corporate-tax-return-t2) and requires Schedule 24 to be filed with it. **Is a wind-up the same as dissolving a corporation?** No. A wind-up of a subsidiary into its parent under section 88 is a reorganization within a corporate group. Dissolving a corporation is shutting it down entirely, which involves a final return to the date of dissolution and normally a clearance certificate before assets are distributed. **Which route keeps my loss carryforwards?** Both routes have rules for the tax attributes of the corporations, including losses, but timing and available amounts differ with the facts, so model the choice rather than assume it. **Do I need advice before combining my corporations?** Yes. The route affects year-ends, filing obligations, loss timing, account balances and the corporate-law steps, and the effective date is fixed by corporate law rather than chosen afterwards. A CPA and a corporate lawyer should review your actual balance sheets and ownership chain first. **How do I answer “Is this the first year of filing after amalgamation?” on the T2?** Answer yes on the first return of the new corporation. An amalgamation creates a new corporation for tax purposes: the predecessors’ tax years end immediately before it, and the amalgamated corporation’s first tax year starts on the amalgamation date. Every return after that first one answers no. ## Combining or closing a corporation? Tell us what each corporation holds and what you want left at the end.
