A share-for-share exchange is a swap, and tax law gives it two doors
A share-for-share exchange is exactly what it sounds like: you give up shares of one corporation and are paid in shares of another corporation instead of cash. Left alone, that is a disposition at fair market value, so the gain built up in the shares you handed over is taxable in the year of the swap even though nothing spendable came back. Two provisions can switch that result off, and which one applies turns on a single question: are you and the corporation issuing the new shares dealing at arm's length?
If you are, section 85.1 of the Act can carry the exchange automatically. There is no form, no deadline and no elected amount to choose. This is the door that covers an owner accepting shares of a purchaser as payment for their company, or a shareholder swept into a takeover of a company they hold shares in.
If you are not, because the corporation on the other side is yours, your holding company or a company your family controls, section 85.1 is unavailable and the swap has to be built rather than assumed. That means a joint election under section 85, an elected amount inside the legal limits, and a T2057 filed on time. Those mechanics are set out in what a section 85 rollover is, and they apply to a share swap exactly as they apply to a transfer of equipment or land.
One transaction that gets the same name belongs to neither door. Swapping one class of your own corporation's shares for another class of that same corporation, the usual first step in an estate freeze, does not move anything to a second company at all; it is a reorganization of the corporation's own capital and runs under its own rules. Owners use the phrase share-for-share exchange for both situations, which is why the first thing we establish is whose shares you are receiving.
The arm's-length route is automatic, and easy to switch off by accident
Section 85.1 defers the gain by default when a Canadian corporation issues its own shares to acquire shares of a taxable Canadian corporation from a vendor who deals at arm's length with it. Broadly, five conditions have to hold:
- The shares you give up are capital property to you, shares of a taxable Canadian corporation held as an investment rather than as trading stock.
- The purchaser is a Canadian corporation paying you with newly issued shares of a class of its own capital stock.
- You deal at arm's length with that purchaser immediately before the exchange, which rules out your own companies and, in substance, companies controlled by people close to you.
- You receive nothing but those shares. Any cash, note or other property in the same exchange takes it outside the provision completely, not partly.
- You do not end up controlling the purchaser or holding more than half the value of its shares once the dust settles, counting shares held by people you do not deal with at arm's length.
Two features make this provision unusual among the rollovers. It works without an election or a filing, so there is no deadline to miss and no penalty regime waiting. And it is a default rather than an obligation: if you would rather realize the gain, you report it on your return for the year of the exchange and the provision steps aside. That opt-out is not a technicality. It is a planning lever, and it is the subject of the second-last section of this page.
The failure mode is the consideration rule. An offer of shares with a modest cash sweetener looks generous and quietly disqualifies the exchange, leaving a fully taxable disposition paid for mostly in paper. Where a purchaser wants to pay part cash and part shares, the fix is structural and belongs in the deal documents before closing, not in a conversation with your accountant the following spring.
Which route your exchange falls into
Most swaps sort themselves quickly once you name the corporation on the other side and the payment it is offering.
| The swap in front of you | How the deferral usually works | What to check first |
|---|---|---|
| A purchaser pays for your company entirely in its own shares | Automatically under section 85.1, with nothing to file | That the purchaser is a Canadian corporation and that you will not control it afterwards |
| A purchaser offers part cash, part shares | Section 85.1 is unavailable; a joint section 85 election with the purchaser can still defer the share portion | Whether the purchaser will co-operate on a T2057, and whether the cash and share pieces can be documented as separate dispositions |
| You exchange operating company shares for shares of your own new holding company | Section 85, jointly elected on form T2057 | Arm's length fails, so the anti-stripping rules test anything you take back besides shares |
| A corporation your family controls acquires your shares | Section 85 again, on a valuation that can be defended | Value shifting to related shareholders, and the shareholder benefit rules that follow it |
| You swap one class of your own corporation's shares for another class of the same corporation | Neither provision; this is a reorganization of that corporation's capital | Whether the new shares genuinely carry the full value of the old ones |
The honest summary of that table is short. Arm's length plus shares only means there is nothing to file and the deferral takes care of itself. Everything else needs design, and usually an election with a deadline attached. If your swap is one step inside a larger cleanup of the group, the sequencing matters more than any single step, which is the point of our guide to corporate reorganizations for owner-managed businesses.
What you hold afterwards, and what travelled with you
You hold new shares carrying the tax cost of the old ones, which means the entire deferred gain came along for the ride. That is the deal the rollover offers: no tax today, and a set of shares whose cost base sits far below their value, so the gain is waiting for whatever disposition happens next. If the new shares are later sold, redeemed or held at death, the postponed gain shows up then.
Paid-up capital travels the same way. The amount that can be returned to you free of tax on the new shares is generally held to the level the old shares carried, so a swap does not create new room to pull value out of a corporation without tax. That matters most when the corporation on the other side is your own holding company, because owners often assume the exchange resets something. It does not. How value actually comes back out of a corporate group, and on what tax rules, is a separate exercise covered in moving excess cash out of an operating company.
The commercial side deserves as much attention as the tax side, and gets less. After an arm's-length swap you are a minority shareholder in somebody else's company. Whether you are paid depends on their dividend policy. Whether you can get out depends on their shareholder agreement, any drag-along or tag-along terms, and whether a market exists for the shares at all. If the purchaser is private, you may be holding an asset you cannot sell, cannot value easily and cannot influence, and no amount of tax deferral compensates for that.
Three practical questions settle it before signing. What are the new shares worth, and who says so. What rights do they carry on dividends, votes and a future sale of the purchaser. And what would it take to turn them into money in three years, or in ten.
When paying the tax now is the better trade
Sometimes the rollover is the wrong answer, and the automatic route can be turned off precisely because Parliament expected that. The most important reason is the lifetime capital gains exemption. Shares of a qualifying small business corporation can shelter a substantial capital gain per person, currently up to $1.25 million on qualifying shares, and that exemption applies to a gain you actually realize. Defer the gain and there is nothing to shelter this year; worse, once you are holding shares of a large or publicly traded purchaser, those new shares will usually never qualify, so an exemption you could have used may be gone for good. Reporting the gain and claiming the exemption is often cheaper than deferring it.
Other reasons to opt out are more arithmetic than strategy:
- Capital losses on hand, carried forward or realized this year, which can absorb a gain you choose to trigger.
- An intention to sell the new shares soon anyway, which turns the deferral into a short delay in exchange for lost flexibility.
- A gain small enough that the tax is not worth planning around, where a clean taxable disposition beats a structure to maintain.
- A purchaser offering a mix of cash and shares, where a deliberate split between a taxable sale and a deferred exchange can produce a better overall result than forcing everything into one box.
The decision is not reversible and it is not obvious from the offer letter, so it belongs in the analysis before the deal is signed rather than in the return that reports it. Where the exemption is in play, the qualification tests have their own holding periods and their own conditions about what the corporation owns, and those are checked well ahead of a closing rather than assumed.
What changes the answer, and how we run it
Six facts decide how a share-for-share exchange should be treated:
- Who is issuing the shares. Arm's length or not is the first fork, and it determines whether anything has to be filed at all.
- Whether any cash is in the deal. A single dollar of non-share consideration in the same exchange closes the automatic route.
- Whether your current shares qualify for the exemption today. If they do, deferring may cost you more than the tax you avoid.
- How much of the purchaser you will own afterwards. Ending up in control, or close to it, can put you outside the automatic rollover.
- Losses and other attributes on your return, which can make a deliberate gain nearly free this year.
- What the new shares let you do. Dividend rights, exit rights and the shareholder agreement decide whether the deferred gain is ever realizable on your terms.
Where the exchange is part of tidying up a structure you already own, rather than a sale to an outsider, the timing question comes first: our view on when a group is worth restructuring at all is in when a corporation should be reorganized. Where the exchange is part of a transaction with a purchaser, the tax analysis has to sit beside the deal terms while they are still negotiable.
We run both as defined-scope work: the qualification review, the valuation position, the election if one is needed, and an instruction memo your corporate lawyer can draft from, so the agreements and the tax filings tell one story. That is a Strategic Projects engagement, and it starts with a free 15-minute discovery call and a written scope and fee before anything begins. If you are choosing a corporate reorganization and tax planning CPA in Ontario for a swap already on the table, the useful test is whether they can tell you, in one meeting, which of the two doors your exchange goes through and what would close it.
