Asset Purchase vs. Share Purchase in Canada: Tax Implications for Buyers

In an asset purchase, the buyer purchases specific assets from the selling corporation and selects which liabilities to assume. The legal entity — the corporation — remains with the seller, along with all undisclosed or unassumed liabilities. The buyer and seller agree on which assets are included in the transaction (equipment, inventory, customer contracts, intellectual property, goodwill, leasehold improvements) and which are excluded (typically the cash balance, accounts receivable unless specifically included, and any legacy liabilities).

The buyer in an asset deal starts with a fresh legal entity — either a new corporation or an existing holding company. This means no historical liability exposure: no legacy CRA disputes, no undisclosed lawsuits, no employment standards violations from before closing, no environmental contamination liability inherited through share ownership. The buyer must negotiate and obtain new contracts with the landlord (for lease assignment), key suppliers, and key customers where the original contract is not freely assignable.

From a tax perspective, the buyer can allocate the purchase price across asset classes and establish a new, higher cost basis for each asset category. This step-up in cost basis allows the buyer to claim larger Capital Cost Allowance (CCA) deductions going forward, reducing taxable income in early ownership years.

In a share purchase, the buyer purchases the shares of the selling corporation from the shareholder(s). The corporation — with all its assets and all its liabilities, known and unknown — transfers intact to the new owner. You become the new shareholder of the same legal entity that ran the business before closing.

Share purchases provide continuity of contracts: the commercial lease, supplier agreements, customer contracts, and licences all remain in the corporation's name. There is no need to negotiate assignments or new agreements with third parties, which simplifies and accelerates closing. Regulated businesses (dental practices, insurance brokerages, liquor stores) where licence transfers are administratively complex often benefit from share purchase structure for this reason.

However, the buyer inherits all of the corporation's historical risk: any undisclosed CRA liability (including payroll deductions, GST/HST remittances, or prior-year reassessment exposure), any pending or undisclosed litigation, any environmental contamination from historical operations, and any employment standards obligations. The representations and warranties section of the Purchase and Sale Agreement and the indemnification and holdback provisions become critically important in share purchases because they are the buyer's only protection against inherited liabilities.

For a Canadian buyer, the asset purchase structure offers two principal tax advantages. First, the cost basis step-up allows the buyer to establish the cost of each acquired asset at its current fair market value rather than its historical depreciated tax value. If you purchase manufacturing equipment that has a net book value of $80,000 in the seller's corporation but a fair market value of $200,000, you can record it at $200,000 in your new entity and claim CCA deductions on the full $200,000 going forward. Over a five-year period, this can generate significant tax savings through accelerated deductions.

Second, in an asset purchase, goodwill is recorded at the allocated fair market value and is eligible for Class 14.1 CCA at a 5% declining balance rate (10% in the year of acquisition under the half-year rule). While this is slower than equipment CCA, it is still a significant benefit compared to a share purchase where no new goodwill cost basis is established.

Additionally, by selecting which liabilities to assume, the buyer effectively acquires a cleaned-up version of the business without the need for extensive indemnification holdbacks. The reduced legal and administrative complexity of a clean-slate asset transaction often translates to lower legal costs, faster closing, and greater certainty of outcome.

From the seller's perspective, a share purchase is almost always preferable for a single, powerful tax reason: the Lifetime Capital Gains Exemption (LCGE). For the 2025 tax year, the LCGE allows a Canadian individual to exempt $1,250,000 in capital gains on the disposition of Qualified Small Business Corporation (QSBC) shares from personal income tax. For a couple who both hold shares and both qualify, that is $2,500,000 of tax-free capital gain.

For a seller with a low adjusted cost base in their shares, the difference between a share sale and an asset sale — which typically triggers income at the corporate level, then dividend or capital distribution tax at the personal level, resulting in a higher effective tax rate — can be hundreds of thousands of dollars. This is why sellers push hard for share purchases, sometimes including it as a non-negotiable term in their initial listing.

To qualify as QSBC shares, the corporation must be a Canadian-Controlled Private Corporation (CCPC), substantially all (90%+) of its fair market value must be attributable to active business assets at the time of sale, and the shares must have been held by the seller for at least 24 months. Businesses that hold significant passive investments (real estate, investment portfolios) inside the operating company may partially lose QSBC status.

In most BC small business acquisitions, deal structure is negotiable. A buyer who insists on an asset purchase needs to compensate the seller for the tax cost of losing the LCGE. The standard approach is to model the after-tax proceeds for the seller under both structures, calculate the tax cost of the asset sale to the seller, and offer a price premium (or alternative consideration) that makes the seller whole after tax while still leaving the buyer ahead due to the asset step-up benefits.

Alternatively, the parties may agree to a share purchase with enhanced representations and warranties and a meaningful indemnification holdback — typically 10–20% of the purchase price held in escrow for 12–24 months — to protect the buyer against post-close liability claims. In this structure, the seller's LCGE benefit is preserved and the buyer's liability risk is mitigated through contractual protections rather than structural clean-up.

A third approach is a hybrid structure: part of the consideration is structured as an asset purchase for high-value equipment and real estate, and the operating business is acquired via share purchase. These structures require experienced M&A legal counsel on both sides and careful attention to tax consequences.

At BizBuy.ca, we model the economics of all three approaches for every deal and present both sides with transparent after-tax analysis so that negotiations are based on real numbers rather than structural preferences divorced from the financial reality.

GST/HST treatment differs significantly between asset and share purchases in Canada. A share purchase is generally not subject to GST/HST — the sale of shares is an exempt supply under the Excise Tax Act. This can simplify the transaction significantly for businesses operating in complex GST/HST reporting environments.

An asset purchase is generally subject to GST/HST on taxable assets (equipment, inventory, leaseholds), unless the transaction qualifies as the sale of a business as a going concern. Section 167 of the Excise Tax Act provides that if both parties are GST/HST registrants and jointly elect Section 167 treatment, the sale of a business as a going concern is deemed to be a supply at nil consideration for GST/HST purposes. This election eliminates the cash flow burden of paying GST/HST at closing and claiming it back as an input tax credit. Most asset purchases in BC where the buyer is a registered business use this election, but it must be filed in the correct form and timeframe.

Provincial Property Transfer Tax (PTT) applies to any real property included in a transaction, regardless of asset or share structure. Buyers should factor PTT into their closing cost budget for any acquisition involving real estate.
