Accounting Implications of Sole Proprietorship to Corp

When you move from a sole proprietorship to a corporation, the most immediate accounting shift is the way you report income: the T1 personal return with Schedule T2125 is replaced by a T2 corporate return. This is not just a new form; it changes how you track revenue, deduct expenses, and plan for tax.

A Section 85 rollover allows you to transfer business assets to the new corporation at their tax cost, deferring the capital gain that would otherwise be triggered at fair market value. Getting the valuation and documentation right is the foundation of a clean transition.

Transitioning Tax Filing: From Personal to Corporate Returns

As a sole proprietor, you reported business income on your personal T1 return using the statement of business or professional activities. Once the corporation is formed, all business income and expenses move to a T2 corporate income tax return. The corporation is a separate legal entity and must file its own return, even if you are the sole shareholder.

Key Changes in Reporting Business Income

Sole proprietorship income is taxed at personal marginal rates; corporate income is taxed at corporate rates, often lower for active business income eligible for the small business deduction.
The corporation must maintain separate books, bank accounts, and financial records from day one; commingling personal and corporate funds can create tax problems.
You will now have two tax filings: the corporate T2 and your personal T1 reporting any salary or dividends you draw from the corporation.

Using Section 85 Rollover for Tax-Deferred Asset Transfer

The Section 85 rollover is the standard mechanism to move assets from your sole proprietorship into the corporation without triggering immediate tax on accrued gains. You and the corporation jointly elect an agreed amount that is at least the tax cost of the asset but not more than its fair market value. In exchange, the corporation issues shares back to you.

We typically prepare the election form and a detailed asset schedule that lists each eligible asset, its tax cost, and the agreed amount. This is not a simple checklist—errors in the election can invalidate the rollover and create unexpected tax.

Eligible assets usually include capital property, such as equipment, vehicles, and goodwill; inventory requires special treatment under the Income Tax Act.
The agreed amount becomes the corporation’s tax cost for the asset, preserving your deferred gain for a future sale.
The election must be filed with the corporation’s first tax return; late filing may be possible but can attract penalties.

Establishing Fair Market Value for Assets

Fair market value (FMV) is what a willing buyer would pay a willing seller in an open market. For most tangible assets, FMV can be supported by purchase records, appraisals, or comparable market prices. For intangibles like goodwill, valuation is more subjective and often requires a professional estimate.

We help clients build a supportable valuation file, because the CRA may review the FMV used in a rollover. If the agreed amount exceeds FMV, the excess may be taxed as a shareholder benefit or dividend. Keep invoices, listings, and written valuation notes.

We have helped many small business owners in construction, restaurants, and professional services complete this transition smoothly. We review your asset list against current market data so the Section 85 rollover stands up to CRA scrutiny.

Corporate Tax Rates and Planning Opportunities

Once incorporated, your business income is subject to corporate tax rates rather than personal marginal rates. For active business income under the annual business limit, a Canadian-controlled private corporation can access the small business deduction, which significantly lowers the tax rate on the first portion of active income.

Accessing the Small Business Deduction

The small business deduction reduces the federal and provincial corporate tax on active business income up to the business limit. To qualify, the corporation must be a Canadian-controlled private corporation and carry on an active business in Canada. Investment income does not qualify.

The business limit is reduced if the corporation’s taxable capital exceeds certain thresholds, or if the corporation earns passive investment income above a set amount.
Active business income means income from a business other than a specified investment business or a personal services business.
We review whether your revenue streams qualify as active business income before relying on the deduction.

Tax Deferral and Income Splitting Benefits

Because corporate tax rates are lower than the top personal marginal rates, you can leave after-tax profits inside the corporation and defer the additional personal tax that would arise if you withdrew all earnings immediately. This deferral is most valuable when you do not need all corporate profits for personal living expenses.

Income splitting through dividends to family members may be possible, but the tax on split income rules limit the benefit for certain family members. We help you model salary and dividend mixes to ensure any splitting remains compliant.

Indirect Tax and Administrative Updates

Incorporation also changes your GST/HST obligations and your business number registrations. The new corporation is a separate person for tax purposes and must register for its own GST/HST account, payroll account, and corporate income tax account.

GST/HST Implications of Incorporation

Your sole proprietorship’s GST/HST account does not automatically transfer to the corporation. You must close the old account (or keep it if you continue some activity) and register the corporation for GST/HST if it makes taxable supplies above the small supplier threshold or if you choose to register voluntarily.

If you transfer business assets to the corporation, the transfer may be treated as a taxable supply for GST/HST purposes in some cases, though certain rollover elections can apply. We assess whether GST/HST is payable on the asset transfer and whether an input tax credit can be claimed by the corporation.

Updating Business Numbers and CRA Accounts

Apply for a new business number for the corporation; the corporation cannot use the sole proprietorship’s number.
Register for a corporate income tax account, GST/HST account, payroll account if you have employees, and possibly an import/export account.
Cancel or update the sole proprietorship’s accounts as needed, and ensure any final returns for the sole proprietorship are filed for the period up to the transfer date.
Notify your bank, suppliers, and customers of the new legal entity and the corporation’s business number for invoicing.

Expense Deductions and Owner Compensation

A corporation can deduct many of the same business expenses as a sole proprietorship, but there are additional deductions available, particularly for employee benefits and certain compensation packages.

Expanded Deductible Expenses and Employee Benefits

A corporation can provide a health and dental plan for employees, including shareholder-employees, and deduct the premiums as a business expense; the benefit may be tax-free to the employee under certain conditions.
The corporation may deduct contributions to a registered pension plan or a deferred profit sharing plan for employees.
Meals and entertainment remain 50% deductible, similar to a sole proprietorship, but the corporation can also deduct certain staff events more generously.
Home office expenses can be reimbursed by the corporation to the shareholder-employee based on actual usage, and the corporation deducts the reimbursement.

Choosing Between Salary and Dividends

As the owner, you will withdraw funds from the corporation either as salary (employment income) or dividends. Salary is a deductible expense for the corporation and creates RRSP contribution room for you; dividends are paid from after-tax corporate income and are taxed at a lower personal rate but do not create RRSP room.

We typically run a side-by-side comparison using current tax rates to determine which mix minimizes the total tax for you and the corporation. The choice also affects Canada Pension Plan contributions if you take salary.

Provincial Tax and Financial Reporting

Corporate income tax has both federal and provincial components, and the combined rate varies depending on where the corporation earns its income. The small business deduction applies at both levels, but the exact rates differ from one jurisdiction to another.

Provincial Tax Rate Differences

While the federal corporate tax rate is uniform across the country, provincial corporate tax rates are set by each province and territory. The small business deduction reduces both federal and provincial tax, but the amount and rate can differ, so the total corporate tax rate on active business income varies by location. Because we work with clients across many regions, we confirm the applicable provincial rate for your corporation each year.

The location of the corporation’s permanent establishment determines which province’s tax rates apply.
Some provinces have a single corporate tax rate for all corporations, while others have a lower small business rate and a higher general rate.
Provincial tax credits and incentives may also differ, affecting the effective tax rate.

Enhanced Financial Record-Keeping and Reporting

A corporation must maintain proper books and records, and may be required to produce financial statements for banks, investors, or regulatory purposes. Unlike a sole proprietorship, which generally does not require formal financial statements, a corporation often needs a balance sheet and income statement prepared in accordance with accounting standards.

The corporation must also keep a minute book containing articles of incorporation, share registers, and director and shareholder resolutions. Annual resolutions are needed to approve dividends, bonuses, or other corporate actions.

Corporate tax returns require a General Index of Financial Information (GIFI) or similar detailed schedules.
Financial statements may need to be audited or reviewed if the corporation exceeds certain thresholds or if required by lenders.
We help set up a cloud-based bookkeeping system so the corporation’s records are always CRA-ready.

Conclusion: Navigating the Accounting Shift

The transition from a sole proprietorship to a corporation changes how you report income, transfer assets, pay indirect taxes, deduct expenses, and maintain records. Each of these areas has specific rules that, when handled correctly, can reduce tax and protect your business.
