What are the tax implications of buying assets vs. shares in Canada?
In an asset purchase, the buyer allocates the purchase price across Capital Cost Allowance (CCA) classes and claims depreciation from day one on stepped-up values; in a share purchase, the buyer inherits the corporation's existing tax pools at their historical cost — no step-up, which is the primary tax disadvantage of the share structure for buyers.
Asset purchases and share purchases have fundamentally different tax consequences in Canada. In an asset purchase, the buyer acquires individual assets and can allocate the purchase price across CCA classes, creating immediate tax depreciation deductions. In a share purchase, the buyer acquires the shares of the corporation and inherits the corporation's existing tax attributes, including undepreciated capital cost (UCC) balances, which cannot be stepped up to reflect the purchase price paid.
Buyers typically prefer asset purchases because they allow for a step-up in tax basis, immediate CCA deductions, and avoidance of corporate liabilities. Understanding the specific tax mechanics of each structure determines the after-tax value of an acquisition.
Asset Purchase: How the Tax Treatment Works
In an asset purchase, the buyer purchases individual assets — equipment, inventory, receivables, goodwill, real property — rather than the shares of the selling corporation. The buyer allocates the total purchase price across these assets and claims tax depreciation through the CCA system on depreciable property.
Under the Income Tax Regulations, CCA rates in Canada vary by asset class: Class 8 (furniture, equipment) at 20% declining balance, Class 10 (vehicles) at 30%, Class 10.1 (passenger vehicles over threshold) at 30%, Class 12 (tools under $500) at 100%, and Class 14.1 (goodwill and eligible capital property) at 5%. The half-year rule applies to CCA in the year of acquisition, limiting first-year depreciation to 50% of the normal rate for most asset classes.
Under the Income Tax Act, Accelerated Investment Incentive (AII) rules introduced in 2018 allow enhanced first-year CCA deductions of up to 150% of the normal rate for eligible property acquired after November 20, 2018, phasing down through 2027. This enhancement significantly increases the present value of tax depreciation for buyers acquiring depreciable assets.
Terminal loss can be claimed by the buyer in an asset purchase if the last asset in a CCA class is disposed of for less than the remaining UCC balance in that class. Conversely, recapture of CCA occurs when proceeds from disposal of a depreciable asset exceed the undepreciated capital cost (UCC) of the class, and the recaptured amount is taxed as ordinary income, not capital gain.
In an asset purchase, the buyer does not assume the seller's corporate liabilities unless explicitly agreed in the purchase agreement, limiting exposure to unknown tax liabilities and historical claims.
Share Purchase: How the Tax Treatment Works
In a share purchase, the buyer acquires ownership of the corporation itself. The corporation continues to exist as a legal entity with all its historical tax attributes intact. The buyer cannot step up the tax basis of the underlying assets to reflect the purchase price paid for the shares.
The acquired corporation retains its existing UCC balances in each CCA class. If the seller's corporation had fully depreciated assets with low or zero UCC, the buyer receives no additional depreciation deductions despite paying full market value for the shares. This is the primary tax disadvantage of share purchases for buyers.
However, a share purchase may be advantageous for buyers when the target corporation holds valuable tax attributes such as non-capital loss carryforwards, investment tax credits, or favourable historical CCA pools that can offset future income. These attributes can provide meaningful value if the buyer can utilize them post-acquisition under the subsection 111(5) restrictions on loss utilization following a change of control.
In a share purchase, the buyer assumes all liabilities of the corporation, including contingent and unknown tax liabilities, which increases risk and typically requires extensive due diligence and indemnification provisions. According to Deloitte Canada's M&A Tax Due Diligence Checklist, buyers commonly conduct detailed tax due diligence in share purchases, including review of prior-year tax filings, outstanding assessments, and contingent liabilities such as unremitted payroll taxes or sales tax audits.
Capital Cost Allowance (CCA) and Depreciation
The ability to claim CCA deductions is the central tax advantage of asset purchases over share purchases. When a buyer purchases assets, the purchase price is allocated to specific CCA classes, establishing a new depreciable base.
In share purchases, cumulative eligible capital (CEC) balances were replaced by Class 14.1 in 2017, and existing CEC pools were transitioned into the new class for corporations holding goodwill or customer lists prior to that date. Buyers acquiring shares inherit these Class 14.1 balances at their historical UCC values, not at stepped-up fair market value.
Change-of-control rules under subsection 111(5) of the Income Tax Act restrict the buyer's ability to utilize the target corporation's non-capital loss carryforwards unless the same business is carried on with a reasonable expectation of profit. This constraint limits the value of inherited tax attributes in share purchases where the buyer intends to materially change the business operations.
Goodwill and Eligible Capital Property
Goodwill acquired in an asset purchase is included in Class 14.1 and depreciable at 5% declining balance annually. This provides a long-term tax deduction stream, though the slow amortization rate means goodwill provides less immediate tax benefit than other depreciable assets.
In share purchases, goodwill remains on the corporation's books at its historical value. If the seller's corporation had no recorded goodwill or minimal Class 14.1 balances, the buyer receives no depreciation benefit despite paying a premium for the business's intangible value embedded in the share price.
GST/HST Implications by Structure
Asset purchases are generally subject to GST/HST on the transfer of individual assets. Share purchases are not subject to GST/HST because the sale of shares is an exempt financial service under the Excise Tax Act.
The going concern exemption under section 167 of the Excise Tax Act applies to asset purchases where all or substantially all (90% or more) of the assets used in a commercial activity are transferred to a purchaser who intends to continue the business, eliminating GST/HST on the transaction. Under the Excise Tax Act, buyers in asset purchases must file form GST44 (Election Concerning the Acquisition of a Business or Part of a Business) jointly with the seller to claim the going concern exemption.
If the going concern exemption does not apply, the buyer in an asset purchase must pay GST/HST on taxable supplies at closing and may recover this amount as an input tax credit if the buyer is GST/HST-registered and uses the assets in commercial activities. The cash flow impact can be significant even if the net tax cost is zero.
Liability Assumption and Tax Risk Transfer
In asset purchases involving real property, provincial land transfer taxes apply in most provinces, with rates and exemptions varying by jurisdiction. Ontario land transfer tax uses marginal brackets with rates from 0.5% to 2.5% depending on property value and type. Share purchases generally avoid provincial land transfer taxes because the ownership of the real property remains with the corporation and does not change hands directly.
In Alberta, there is no provincial land transfer tax, making asset purchases involving real property less costly compared to provinces like Ontario or British Columbia.
In an asset purchase, the purchase price allocation agreed upon between buyer and seller governs each party's tax reporting — the seller calculates gains on each asset class based on the allocated amounts, and the buyer records the initial cost base or UCC in the appropriate CCA class. The allocation must be negotiated carefully in the asset purchase agreement because it determines how the sale proceeds are taxed for the seller and what CCA deductions are available to the buyer going forward.
Section 22 of the Income Tax Act allows a seller to deduct accounts receivable write-offs as a business expense and allows the buyer to include the receivables in income at their actual value, making this election tax-efficient for both parties in asset sales.
When Each Structure Makes Tax Sense for Buyers
Buyers typically prefer asset purchases because they allow for a step-up in tax basis, immediate CCA deductions, and avoidance of corporate liabilities. Asset purchases deliver immediate cash tax savings through accelerated depreciation and eliminate exposure to unknown historical liabilities.
Share purchases make tax sense for buyers when:
- The target corporation holds significant non-capital loss carryforwards that the buyer can utilize under subsection 111(5) restrictions
- The seller insists on share sale to access the Lifetime Capital Gains Exemption (LCGE) and the buyer negotiates a price reduction reflecting the inferior tax position
- The business holds licenses, contracts, or regulatory approvals that are non-transferable and would be lost in an asset sale
- The target corporation has favourable tax elections or historical structures (e.g., beneficial tax treaties, grandfathered tax positions) that would be forfeited in an asset sale
Buyers should model the after-tax cash flows of both structures before agreeing to a share purchase. The difference in tax depreciation value over 5–10 years can be material relative to the purchase price.
Cross-Border Considerations for Non-Resident Sellers
When a non-resident sells shares of a Canadian corporation, the buyer may be required to withhold 25% of the purchase price under section 116 of the Income Tax Act unless the seller provides a clearance certificate from CRA. Buyers who fail to withhold when required become personally liable for the seller's Canadian tax liability.
The section 116 withholding requirement applies to share sales where the shares derive their value principally from Canadian real property. Buyers must confirm the seller's residency status and obtain legal advice on withholding obligations before closing.
In asset purchases involving non-resident sellers, similar withholding rules apply to the disposition of taxable Canadian property. Buyers must ensure the seller obtains a section 116 certificate or withhold the required amount and remit it to CRA within the prescribed timelines.
