What Goes Wrong When Owners Move Assets Between Their Own Corporations?

Where rollovers fail: four stages, one pattern

Rollover mistakes cluster at four stages, and knowing the stage tells you how fixable the error is. Mistakes made before the deal, in the eligibility check and the valuation, poison every number that follows. Mistakes made in the design, the consideration and the elected amounts, create tax that the law then locks in. Mistakes at filing are the most mechanical and the most forgiving, because late elections have a defined, if expensive, cure. Mistakes after closing are the slow ones: nothing hurts for years, and then a sale, a reassessment or a new accountant finds a paper trail that cannot support what everyone believes happened.

The pattern behind all four stages is the same: the transfer happened in a hurry, the tax numbers were assumed rather than computed, and no single advisor owned the whole file. Here is the map, and the sections that follow walk through each stage:

Before the deal: eligibility and valuation errors

The first error is assuming everything in the company qualifies for the rollover. Most business property does, but the exceptions are exactly the assets owners forget to check: real estate held for resale cannot roll under section 85 at all, accounts receivable usually belong under a separate election that preserves bad-debt deductions inside the corporation, and cash needs no election because it carries no gain. Sweep the wrong asset into the T2057 and that line of the election simply does not do what everyone thinks it does; the transfer becomes a taxable disposition hiding inside a tax-deferred one.

The second error is the guessed valuation. Every limit in section 85 is measured against fair market value, and in an owner-managed business the hardest value is goodwill, the worth above the identifiable assets. Round numbers with no working papers behind them invite the CRA to substitute its own figure years later, and by then the evidence is stale. The protection is boring and effective: a documented valuation prepared at the time of the transfer, plus a price adjustment clause in the agreements so that if the value is later revised, the share consideration adjusts instead of the difference becoming a taxable benefit. A clause only protects a genuine attempt at fair value; it does not launder a guess.

A close cousin of both errors is sequencing: the transfer closes first and the accountant hears about it afterward. By then the consideration is fixed, the debt is assumed, and the elected amounts have to be reverse-engineered around decisions already made, which is how avoidable gains become unavoidable ones. The valuation, the eligibility check and the elected-amount schedule are pre-closing work by nature; a rollover reviewed after signing can only be graded, not improved.

The third error is transferring property whose tax cost nobody can prove. The elected amount floors run off adjusted cost base and undepreciated capital cost, and those numbers live in old returns, purchase documents and depreciation schedules. If the records are missing, the floor is a guess, and every downstream number, the gain, the safe note size, the cost base carried into the corporation, inherits the uncertainty. Rebuilding the cost file is the first task on every rollover we run, precisely because it cannot be rebuilt credibly after a reassessment starts.

In the design: consideration, boot and paid-up capital errors

Design errors are the expensive ones, because the Act converts them directly into tax. The most common by far is treating assumed debt as invisible. When the corporation takes over the mortgage or line of credit attached to transferred property, that assumption is non-share consideration, boot, whether or not any document says so, and the elected amount can never sit below the boot. Debt above the tax cost of the property forces a gain in the year of transfer; we see this so often that it has its own page on whether liabilities can be transferred in a section 85 rollover.

The rest of the design errors form a short, repeating list:

• A promissory note above tax cost. Boot up to cost comes out tax-free over time; boot beyond it triggers gain dollar for dollar. Owners who size the note by what they want, rather than by the boot room the numbers allow, buy an immediate tax bill.
• No share taken back. The election requires at least one share of the transferee. A transfer papered entirely as a sale for a note is not a rollover, no matter what the T2057 says.
• Holdco insertions done as if section 84.1 did not exist. Moving shares of one company into another company you control, and taking back notes or high paid-up capital supported by value never taxed in your hands, invites the Act to recharacterize the excess as a taxable dividend. This single rule turns more DIY rollovers into tax bills than any other.
• Value quietly shifted to family shareholders. Elect low while a spouse or children already hold shares of the transferee and a benefit rule can push the elected amount up and tax the difference. Share terms and shareholdings have to be checked before the elected amounts are set.
• Stated capital set at full value. Lawyers sometimes record the shares at fair market value in the corporate records while the tax rules grind paid-up capital down to roughly the elected amount minus the boot. The grind wins for tax, and an owner who later relies on the legal number and pulls out capital can trigger a deemed dividend nobody budgeted for.

None of these are exotic; they are the standard failure modes of the standard transaction. The machinery that prevents them, elected-amount schedules, boot budgets and share terms designed together, is laid out in our full guide to section 85 rollovers for business owners.

At filing: the T2057 errors

Filing errors all descend from one misunderstood sentence: the joint election is due on the earliest date either party has to file a return for the year of the transfer. If the corporation's year-end comes first, the corporate deadline governs your election too, and a transfer made late in a corporate year leaves a short window that has nothing to do with April. Treating the T2057 as personal-tax-season paperwork is how careful people file late. Whether a given transfer needs the election at all is its own threshold question, covered in when a section 85 election is required.

The form itself generates a second family of errors. One T2057 covers one transferor and one corporation, so two spouses transferring together each file their own; both parties must sign; each property needs its own elected amount within its own limits; and the consideration disclosed must match the legal documents exactly. When the election and the purchase agreement tell different stories, the CRA is entitled to rely on whichever version produces more tax, so the schedule of elected amounts should exist before the lawyer drafts, not after.

Retention is the quiet half of filing. The CRA's questions about a rollover tend to arrive years later, when a reassessment window opens or a subsequent transaction draws attention, and by then the only defence is the file: the signed election, the valuation working papers, the cost base support and the agreements, kept together and findable. An election that was filed perfectly but cannot be reconstructed defends nothing.

A missed deadline is repairable, at a price that grows monthly. The CRA accepts an election filed up to three years late as of right, with a penalty for every month of lateness; beyond three years, or to amend an election already filed, you need the CRA to agree the request is just and equitable, which is discretionary. The practical rule: put the T2057 into the closing checklist beside the transfer agreement, and never let a rollover close without a named person owning the filing date.

After closing: the follow-through errors

The rollover is not finished when the agreements are signed, and the quiet months afterward are where the last family of mistakes lives. The transaction exists in three places, the legal records, the tax filings and the accounting records, and all three have to agree. In the files we inherit, they usually do not:

• The books were never adjusted. The corporation records the property at a value that matches neither the elected amounts nor the legal consideration, and five years of financial statements compound the mismatch.
• The note was never documented. The shareholder draws against a promissory note that exists only in the accountant's memory, with no terms, no paper and no support if the CRA asks why the withdrawals are not income.
• The share register and minute book were never updated, so the shares the election says were issued cannot be proven to exist.
• The other taxes were ignored. A section 85 election does nothing for HST or Ontario land transfer tax. Asset transfers between entities can attract HST unless a relieving election is filed on time, and real property moving between even related companies can trigger land transfer tax. Each needs its own analysis and its own filing.

These errors surface at the worst moments: a purchaser's due diligence, a bank's security review, a CRA audit, or the eventual sale where nobody can establish the cost base of anything. The fix at that point is reconstruction, which costs multiples of what posting the entries in the month after closing would have cost.

What raises the risk, and how mistakes get fixed

Five facts predict how much can go wrong on a given transfer:

• Debt on the property. Leverage near or above tax cost is the single biggest error generator.
• Shares versus hard assets. Share transfers to a related corporation bring section 84.1 and its deemed dividends into play.
• Who else holds shares of the transferee, because family shareholdings trigger the benefit rules.
• The quality of the cost records, which set every floor and every safe note.
• The calendar: the year-ends of both parties set the T2057 deadline, and the HST and land transfer tax filings run on their own clocks.

Discovered errors sort into three bins. Late or missing elections have the statutory cure described above. Valuation shortfalls can sometimes be absorbed by a price adjustment clause, if one was drafted and the original attempt at value was genuine. Design errors, boot over cost, section 84.1, benefits conferred, usually cannot be undone; they can only be managed going forward, which is why prevention is the whole game. We run rollovers as defined-scope engagements under Strategic Projects: one schedule that the valuation, the legal documents, the election and the bookkeeping entries all follow, with a written fee agreed before work starts. If you are choosing a corporate reorganization and tax planning CPA in Ontario, ask one diagnostic question: who, by name, owns the T2057 deadline and the post-closing entries? If the answer is vague, this list is your future. Our restructuring practice exists so it is not.
