Two years before you sell: the runway that saves the exemption

The runway on a share sale is at least two years, and it runs out backwards. One of the tests deciding whether your shares qualify for the lifetime capital gains exemption — up to C$1,275,000 of sheltered gain for 2026 dispositions — measures a period that ends on the day you close and runs backwards from there. So the balance sheet you are carrying this month is already inside the window for any deal that closes two years from now. Clean the corporation up after a buyer appears and you generally fix what it looks like on closing day while leaving the history behind it exactly as it was.

The tests themselves are set out in the exemption primer. This piece is the calendar: when the clock starts, what order the cleanup runs in, and what a buyer’s accountant asks for once there is a deal on the table.

The clock ends on a date you don’t control

Most tax deadlines start from a date you already know — a year-end, a filing, a purchase. This one ends on a date that does not exist yet. The backward-looking test measures the twenty-four months ending on the closing date, which means the window for a deal closing in April 2029 opens in April 2027, and the window for a deal closing next autumn opened last autumn and is beyond reach.

That asymmetry decides the whole plan. A closing that slips is good news: the window slides forward with it, and months you had already cleaned stay clean. A closing that arrives early is the expensive case, because the window reaches further back into years you were not managing. Owners plan to the date they intend and get tested against the date that happens.

The second thing to price is that the cleanup itself takes time. If moving surplus out sensibly takes two tax years, and the window needs to be clean before it opens, then the honest planning horizon is the look-back period plus the cleanup — closer to four years than two. Two years is the point at which the options narrow, not the point at which you start.

Cleaning the balance sheet is a sequence, not a transaction

The routes out — dividends up to a holding company, dividends paid personally, shareholder loans repaid, cash spent on operating assets, business debt retired — are listed in the primer. What the primer does not do, deliberately, is put them in order. Four things set the order:

• Some routes create tax in the year you use them. A dividend paid personally is taxed on your return that year, and a large one generally brings personal instalments with it the year after. Moving the whole surplus in a single year converts a purification into a personal tax bill payable long before any sale proceeds exist.
• Some routes have to exist before they can be used. A dividend to a holding company needs the holding company incorporated, the shares issued, and a directors’ resolution dated before the money moves — not reconstructed afterwards.
• Repaying a shareholder-loan receivable is a conversion, not a removal. The money you owe the corporation stops being a receivable and becomes cash, and cash has no operating job either. It is step one of two, and owners who stop there believe they have purified.
• The business still has to run. Working capital the business genuinely needs is generally treated as used in the business; strip past that line and you create a covenant or bonding problem in exactly the year you need the corporation to look ordinary to a buyer.

A holding company is a lead-time item

Where the surplus is heading upstairs, the structure is not a same-week decision. Standing a holding company over a company that already has value means a share exchange and legal work, generally a valuation to support it, a second year-end, a second set of books and a second T2 — the corporation’s income tax return, due six months after its year-end, June 30 for a December 31 year-end, with the balance of tax generally due sooner than that. The deadline table has the rest.

Whether a holdco belongs in the picture at all is its own five-question test, and a near sale is only one of the five. What matters to the calendar is that the answer has to be reached, and the entity built, before the first dividend can move — and that the running record of how much income has already been taxed behind each of those dividends gets built as they happen rather than assembled two years later.

An illustrative calendar: a sale targeted for April 2029

Round numbers, December 31 year-end, and today is the middle of 2026.

Your operating company holds C$1,200,000 of assets. C$800,000 of it works — receivables, equipment, the fit-out. C$300,000 sits in a term deposit and a portfolio. C$100,000 is owed to the corporation by you personally. Roughly a third of the balance sheet has no operating job.

Target the closing at April 2029 and the window for it opens in April 2027 — about nine months of room in which changes leave no trace inside the measured period. So the sequence has a deadline that is not the sale date. During 2026 the shareholder loan is repaid, which turns C$100,000 of receivable into C$100,000 of cash and leaves C$400,000 of non-operating assets rather than removing anything. C$250,000 goes out as a dividend before the end of 2026. The remaining C$150,000 goes out in January 2027, still ahead of the window — two personal tax years rather than one, with the instalments that follow spread the same way. From April 2027 forward, the corporation carries operating assets only, and the whole of the period behind an April 2029 closing sits on a clean balance sheet.

Now move the date. If the deal slips to October 2029, the window slides with it and you are strictly better off. If an unsolicited offer lands in November 2027 and closes in March 2028, the window reaches back to March 2026 — which contains the term deposit, the portfolio and the receivable for most of a year. Same cleanup, same discipline, wrong deal date, and what that costs is arithmetic rather than judgement.

Diligence reads the file you already kept

A buyer’s accountant works to the buyer’s calendar, and it is short. What gets requested is ordinary and is either sitting there or is not: the minute book current, with the share register and every dividend declared by resolution before it was paid · returns filed and assessed with nothing outstanding — T2s, GST/HST, payroll, T5018s where they apply · intercompany and shareholder-loan balances that agree on both sides · GST/HST and payroll accounts reconciled to the ledger rather than to the last remittance · closed year-end packs with the financial statements tied to the returns as filed. What has to be kept, and for how long, is a separate question with its own rules; diligence just tests whether you did.

Gaps rarely kill a deal. They get priced. An unresolved CRA matter becomes a holdback against the purchase price, a shareholder-loan balance nobody can explain becomes an adjustment, and both are settled by the party with less information about their own company — which is you, in the month you are least able to go looking.

What Cadence does

We work the calendar back from the earliest date a deal could plausibly close rather than the date you have in mind, because that is the one the tests will use. That means naming which route each piece of surplus takes, which tax year each tranche lands in, and what the instalments do afterwards — and saying when the honest answer is that the window is already open and the plan has to change shape. That multi-year sequencing is tax planning work and sits in the year-round packages; the C$3,000 Compliance tier covers the annual returns, not a plan that spans them. When diligence starts, we produce the corporate and personal filing history from the file we already keep and deal with the buyer’s accountant directly. Where a buyer wants reviewed or audited statements, that is assurance work — we are not a CPA firm, so we prepare the underlying reporting and work alongside the firm that signs it. For software companies and managed service providers, where a first offer often arrives before anyone has decided to sell, that earliest-date calendar is the only version worth running.
