Should I Buy Assets Personally or Through My Corporation?

Cheap Dollars, Expensive Mistakes

The instinct behind this question is sound arithmetic. A corporation paying the small business rate keeps roughly 87.8 cents of each active dollar it earns; an owner in Ontario's top brackets keeps less than 47 cents of a dollar drawn out. The corporation's pile is nearly twice as tall, so buying from the corporation's pile feels obviously right. The tax system knows this instinct well, and three sets of rules stand between it and a free lunch: the shareholder benefit provisions, which tax personal enjoyment of corporate property at full personal rates; the passive investment rules, which grind the small business limit when the corporation's money sits in portfolios instead of the business; and the capital gains exemption tests, which quietly fail when the operating company fills up with assets that are not the business. The cheap-dollars advantage is real, but it is conditional, and the condition is always the same: the asset must genuinely serve the business. Everything on this page follows from that one condition.

The Asset-by-Asset Map

Where each asset belongs, and the rule that puts it there.

Vehicles: The One That Is Actually a Calculation

Vehicles get their own section because they are the one major asset where the answer legitimately flips with the facts. A corporately owned vehicle produces deductions and input tax credits, and it also produces a standby charge on your T4 for personal availability, plus an operating benefit for personal kilometres the corporation funded, both calculated whether the savings materialized or not. Against that stands the simple alternative: own the vehicle personally and have the corporation pay the CRA's per-kilometre allowance for business driving, 72 cents for the first 5,000 kilometres and 66 cents beyond for 2026, tax-free to you and deductible to the corporation, with nothing required but a log.

The House Is Not a Discussion

Every few months an owner asks whether the corporation should buy the family home, because the money is sitting there and drawing it out costs tax. The answer is no, and it is one of the few unqualified answers in tax. A corporately owned home surrenders the principal residence exemption, which shelters what is for most Canadians the largest tax-free gain of their lives, and replaces it with a corporation paying tax on any future gain. Living in the corporation's house rent-free creates a shareholder benefit, taxed to you annually at the value of that housing, while the corporation deducts essentially nothing. The correct route to a home purchase runs through planned remuneration: a salary and dividend design that moves the down payment out at the lowest combined cost, ideally starting a year or more before the purchase so the drawdown does not spike a single tax year and the lender sees the income history they need. The corporation's role in your home is to fund it through your remuneration, never to own it.

Investments: The Deferral and Its Two Prices

Retained earnings invested inside the corporation are the legitimate reward of incorporating: money that would have shrunk past 53% on the way out instead compounds from a base taxed near 12.2%. Two prices attach, and both are asset-purchase decisions in disguise. First, passive investment income above $50,000 in a year grinds the small business limit by $5 for every excess dollar, eliminating it at $150,000, applied with a one-year lag, so this year's portfolio yield sets next year's tax rate on the business itself. Second, the lifetime capital gains exemption, now sheltering up to $1,250,000 of gain per person on qualifying shares, demands a corporation substantially devoted to active business at sale and majority-active for the two prior years; a corporation that spent a decade accumulating portfolios, surplus cash and personal-use assets can fail those tests entirely. The planning answer is usually structural, separating investments from the operating business and purifying well before any sale, and it is covered properly in our active vs passive income guide. The purchase-decision answer is simpler: every passive asset bought inside the operating company should be bought knowing these two meters are running.

The Questions to Answer Before Any Major Purchase

The checklist we run for clients, in the order that settles most cases fastest.

• Who actually uses it, and in what proportion? Business use points corporate; personal use points personal; mixed use demands the calculation.
• Does the corporation recover the HST? A registrant buying business assets claims input tax credits a personal purchase never sees.
• What taxable benefit does personal access create? If the honest answer is a standby charge or a housing benefit, price it before buying.
• What does it do to the exemption tests? Passive and personal-use assets inside the operating company erode qualification for the $1,250,000 exemption.
• How is it financed, and does the interest deduct? Interest follows use; keep corporate borrowing on corporate assets and never blend accounts.
• What does the exit look like? Recapture, capital gains and getting proceeds out are decided at purchase, discovered at sale.
• Does a lender need to see personal income first? A mortgage application next year changes this year's remuneration plan.

Seven questions, one afternoon, and the decision stops being instinct. The modelling matters most for anything costing more than a modest vehicle, because at that size the gap between the right and wrong structure is measured in five figures, and the friction of reversing a corporate purchase later, taxed out at fair market value, means the first decision is usually the only inexpensive one.
