Tax Planning for Selling Your Canadian Business
Plan the sale before the paperwork locks in your choices
Selling a Canadian corporation starts with understanding what is being sold, who receives the proceeds and what cash remains after tax, debt and transaction costs. Bhundhoo Tax helps owner-managed businesses in London, Ontario and across Canada organize the financial information and compare the tax implications with their legal advisers.
For incorporated e-commerce founders and other small-business owners, a useful plan connects the proposed deal with your next goal: retirement, another venture or a gradual transition. Start the conversation before signing terms that could limit your options.
Asset sale or share sale: what changes?
Asset sale: the corporation sells specified business assets. The agreement may allocate value to inventory, equipment and goodwill. Review the tax consequences within the corporation and the separate implications of paying proceeds to shareholders.
Share sale: shareholders sell their ownership shares. The corporation continues to own its assets. The seller's tax position, share history and eligibility for available deductions need their own review.
The headline price alone does not tell you which proposal leaves you better off. Compare taxes, debt, professional fees, payment timing, holdbacks and the buyer's proposed conditions. Your lawyer should review contractual risks alongside the tax analysis.
See the CRA's selling a business guidance.
A practical three-stage planning process
1. Review your records and objectives
We start with ownership, financial statements, tax filings, shareholder balances and your intended timeline. Identify missing records and outstanding CRA correspondence early. For an online business, reconcile marketplace and payment-processor activity with the books, including refunds, fees and inventory.
2. Compare the proposed structures
Review the asset or share-sale proposal, document assumptions and estimate after-tax cash flow. Consider whether qualified small business corporation share rules are relevant, without assuming every corporation qualifies. Coordinate the tax questions with your lawyer before the agreement is finalized.
3. Prepare for closing and what follows
Build a calendar for payments, filings and follow-up work. Allow for costs and amounts that may remain tied up after closing. Plan how proceeds will support your personal and business needs rather than treating the full purchase price as immediately spendable.
What should you bring to the first meeting?
- Recent financial statements, corporate tax returns and CRA notices.
- Shareholder and ownership records, including acquisition dates and costs where available.
- Asset, inventory, loan and shareholder-loan schedules.
- The offer, letter of intent or draft purchase agreement, if one exists.
- Your expected timeline, proposed payment terms and plans after the sale.
For e-commerce businesses, also identify the platforms, payment processors, inventory locations and any cross-border activity. Share confidential records through an agreed secure process.
Business-sale tax planning: common questions
When should I involve a CPA?
As early as possible, ideally before negotiating or signing the principal terms. Early review gives your advisers time to examine records, identify eligibility questions and compare alternatives. If an offer is already on the table, bring it to the first meeting.
Can I claim the lifetime capital gains exemption?
Potential eligibility depends on the property sold and your circumstances. A sale of qualified small business corporation shares may qualify for the capital gains deduction; incorporation alone is not enough. Ownership and asset-use conditions require review. Read the CRA's qualified small business corporation share guidance.
Will GST/HST apply to the sale?
It depends on the transaction. A qualifying sale of a business or part of a business may allow the buyer and seller to make an election. Do not assume a sale automatically qualifies or omit tax without checking the conditions and filing requirements. See the CRA's GST/HST guidance on selling a business.
Does reinvesting the proceeds automatically defer tax?
No. Buying another investment or starting a new business is not, by itself, a general tax deferral. Any proposed rollover or deferral must meet the requirements of the specific provision. Ask for the eligibility conditions and deadlines before committing funds.
Can you guarantee a particular tax saving?
No. The outcome depends on the facts, applicable law and the agreed transaction. A useful comparison shows its assumptions and limitations rather than promising a fixed percentage saving.
